Maryland Sheep & Goat Directory

We are continuing to collect data for the new Maryland Sheep & Goat Directory, which will facilitate communication between sheep/goat producers and buyers of sheep and goat products. The survey for the directory can be submitted in person, by fax, mail, or e-mail. The survey can be downloaded from the web at http://www. sheepandgoat.com/directory.html. The directory will be accessible on the Internet in several months.


New Small Ruminant Research Program in Maryland

A new research program is being established at the Western Maryland Research & Education Center (WMREC) in Keedysville (Washington County), Maryland. Ten acres of pasture, previously used to graze dairy heifers, is being developed for sheep and goat grazing. The fencing has been modified to contain small ruminants and control predators. It is a six strand, high-tensile electric fence with all wires carrying a charge. The first wire is approximately six inches off the ground. Movable metal shelters (port-a-huts) will be used to provide protection from the elements. Animals will only be maintained during the spring to fall growing season.

The goal of the research program at WMREC is to conduct applied research and demonstration projects. The initial project will involve the grazing of up to 90 Boer cross meat goat kids, obtained from the University of Maryland Eastern Shore. Two systems of grazing will be compared: continuous vs. rotational (~2 week rotation). The goats will be monitored for growth rates and parasite levels. At the conclusion of the study, the goats will be used for a marketing study to compare marketing goats at local vs. regional livestock auction markets.

In addition, hair sheep lambs will be used to graze a 4 acre field that contains several plantings of walnut trees. This will be a demonstration project to show how livestock grazing can be incorporated with tree production. This practice is called agroforestry or silvopasture.

Editor’s note: If you have opinions as to the type of small ruminant research that you would like to see conducted in Maryland in the future, do not hesitate to contact Susan, Niki, or Willie.

Maryland Receives Small Ruminant IPM Grant

The Western Maryland Research & Education Center in Keedysville recently received a Northeast SARE grant to conduct a three year research and education project related to Integrated Parasite Management (IPM) in sheep and goats.

The primary goal of the grant project will be to teach producers how to perform their own fecal egg counts and to apply the FAMACHA1 technique to their animals to determine the need for anthelmintic treatment. IPM workshops will be held at various locations in Maryland and possibly neighboring states. The project will also involve on-farm studies to test for anthelmintic resistance and to determine the effectiveness of various treatments and management practices.

1 FAMACHA is a technique whereby you look for signs of anemia (barber pole infection) by examining the sheep/goat’s lower eyelid. A bright, reddish pink color is indicative of good health and no need for deworming.

Editor’s note: If you would like to have a Fecal Egg Counting/FAMACHA workshop in your county or region, please contact Susan, Niki, or Willie. Also, let us know if you would like to do a field study on your farm.


What is the Potential for Milking Sheep?

Sheep have been raised for milk for hundreds of years. Milk production from sheep is an important agricultural enterprise in the countries near the Mediterranean Sea. In the United States, there are few sheep dairies, but it is a growing enterprise in many parts of the country, such as the New England states and the Midwest.
Most sheep’s milk is processed into cheese, with smaller amounts going into yogurt, ice cream, and fluid milk. Some famous world cheeses made from sheep’s milk are Roquefort (from France) and Feta (from Greece).

The U.S. imports about 38 thousand tons of sheep-milk cheese annually, representing half of the world trade in the cheese. This amount has more than doubled in the past 15 years, according to Michael Thonney from Cornell University. Less than 100 tons of sheep-milk cheese are produced in the U.S. each year, and Thonney believes there is a large potential market for this product.

According to researchers at the University of Wisconsin Spooner Research Station, with a small investment in milking facilities and equipment, a sheep producer can increase his/her gross income by approximately 75% by milking sheep (compared to producing just meat and wool). Sheep milk can be made into cheese on the farm or sold to cheese plants which make specialty sheep cheeses or blend sheep’s milk with cow and/or goat’s milk. Sheep milk can be frozen without harming its cheese-making capabilities. This allows producers to stockpile their milk until they have enough to ship.

Domestic sheep breeds which have not been selected for milk production can be expected to produce 100 to 150 lb. of milk over a 90 to 100-day lactation period, whereas dairy ewes can average three pounds of milk per day over a 150-day lactation period. The “Holstein” of the sheep world is a German breed called East Friesian. At the University of Wisconsin, Friesian-cross (¼ blood) ewes are producing a little over twice the milk per day as the Dorset crosses that serve as controls.
In a sheep dairy, milking generally starts after lambs are weaned at about 30 days of age. Yield can be increased substantially if lambs are raised on milk replacer and milking is initiated 24 to 36 hours after parturition. Wisconsin researchers determined the most profitable management system is to leave lambs with the ewe for half of the day and milk the ewe once per day.

Dairy sheep can be milked by hand or machine, at stands or in a milking parlor with a pit. They are milked from behind. A separate milking area and milk room are needed. Dairy ewes need to be calm and well-mannered and have well-set udders. It goes without saying that they should be prolific ewes that produce lambs with good weaning weights.

Sheep’s milk is higher in fat, protein, and total solids than goat’s or cow’s milk and yields more cheese. Four to five pounds of sheep milk produces a pound of cheese, whereas it takes eight to nine pounds of cow milk or goat milk to produce a pound of cheese.

Maryland Wool Pool: One Day Only for Delivery of Wool

The 46th Annual Maryland Wool Pool will be held July 2 and 3 at the Maryland State Fairgrounds in Timonium. Wednesday, July 2 will be the only day for delivery of wool to the pool. Wool will be accepted between 7:30 a.m. and 3:00 p.m. There will be three lines to accept wool. Two of the lines will accept loose wool. The third will handle wool baled in square bags. Any producer bringing wool to the pool in nylon square bags weighing 250 pounds or more will receive a 5 cent per pound bonus, plus a new bag. Smaller lots of wool can be delivered in plastic trash bags or loose in vehicles. Wool delivered in polypropylene bags will be refused. Wool delivered in burlap bags will be discounted 3 cents per pound. Wet wool will not be accepted. “Wool” from hair sheep or hair sheep crosses will not be accepted.

This year’s Maryland Wool Pool was purchased by Chargeurs, Inc. of Jamestown, South Carolina, at the following prices:

Grade
Price per lb.
Choice white-face
0.42
Medium white-face
0.32
Coarse white-face
0.31
Non white-face
0.30

0.15

Checks will be mailed to consigners within several weeks of the pool. The price received for wool will be the price listed above minus a deduction for wool pool expenses (usually around 6 cents per pound). Maryland Sheep Breeders Association dues of $15 will be deducted on wool sales over $30. The MSBA Board of Directors has made a policy that no refunds will be made. MSBA members receive the quarterly, “Maryland Sheep News.” If membership dues are not deducted, MSBA annual dues can be sent to Kris Thorne, 2367 Carrollton Road, Westminster, MD 21157.

Questions or concerns regarding the Maryland Wool Pool should be directed to pool manager Rich Barczewski at (302) 857-6410 during the day and at (302) 659-1211 in the evenings prior to 9 p.m. Rich can also be reached via e-mail at rbarczew@dsc.edu.

Apply for LDP’s Before Losing Beneficial Interest in Wool

Producers planning to apply for loan deficiency payments (LDP’s) or marketing assistance loans must make application with their local FSA office before losing beneficial interest in their wool. Beneficial interest is lost when wool is delivered to a wool pool or sold. Each Tuesday, the USDA posts rates to calculate the loan deficiency payments at http://www.fsa.usda.gov/dafp/psd/ MKTPRICLEAN1.htm.

A Comparison of three Sire Breeds for Low-Input Lamb Production

by Niki Whitley
University of Maryland Eastern Shore
nwhitley@mail.umes.edu; (410) 651-6194

Northeast SARE (Sustainable Agriculture Research and Education) has funded a grant in which UMES and Maryland Cooperative Extension (Niki Whitley and Susan Schoenian) will be looking at utilizing low- input Katahdin hair sheep females with three different sire breeds to determine which sires will economically increase carcass quality on a pasture production system. The second phase of the study will consist of producers being able to use one of the three sire breeds on their own farms to determine if any of the three will help to increase their individual farm profits (to help sustain the small farm lifestyle).

The three sires being tested include a “traditional” lamb breed – the Suffolk and two “import” types – the Texel, a wool sheep bred extensively for and excelling in muscling and carcass traits and the White Dorper, a hair sheep also bred for and excelling in muscling and growth. Right now, the sires we have are a yearling Suffolk with outstanding growth EPDs, a 3-year old proven White Dorper sire and a 6-year old Texel with proven carcass contest sire winners in his bloodline.
The plans are to breed 20 to 40 ewes to each sire and produce the lambs in as low-input a management system (as much on pasture) as possible. Producers will be involved in the research through workshops on ultrasound and parasite resistance studies between the breeds and again, through the potential use of the sire breeds in their own flock.

If you are interested in learning about the use of ultrasound to look at carcass traits (to select better sires, etc.) and/or how to use fecal egg counts to determine internal parasite loads, please do not hesitate to contact me or Susan.

Use of Prostaglandin (Lutalyse) to Synchronize Breeding in Meat goats

by Dr. Niki Whitley

When I first began working at the Ruminant Farm at UMES, the goats were bred in the fall using natural breeding for a 45-day breeding period (to accommodate two 21-day cycles). That meant kidding (and labor) was spread out over at least 45 days. Being a reproductive physiologist, the first and second things I wanted to do with the animals was to synchronize breeding and organize out-of-season (summer) breeding in the goats (and sheep). Being new to goat production, I did not know what to use to synchronize goats. Using my knowledge of cattle reproduction and realizing that during the breeding season goats estrous (heat) cycles are a lot like cattle cycles, I decided to conduct an informal, “on-farm” experiment in order to get the goats bred within a 2-week period. Our farm manager organized all the labor and I was mostly just the “idea” person. We only had 20-something animals. A few were Nubian, so I left them out of the study and used only our 19 Boer and Boer-crossbred animals (because breed does make a difference).

It is known that drugs that work like prostaglandins (hormones found naturally in animals and people) have been used in dairy goats to synchronize estrus (heat) during the breeding season, but little is known about use of prostaglandin in meat goats. In mid-October, we took the 19 cycling does (that had seen, heard and smelled bucks but had no fence-line contact yet) and put them into two groups. We gave one group of 8 does 1.5cc Lutalyse (from Pharmacia & Upjohn) intramuscularly the day we put in mature bucks wearing a marking harness. The other 11 did not get any treatment yet.

We checked for marks on all does 4 days after putting the bucks in, and any of the 19 does that were not marked were given 1.5cc Lutalyse IM (some for a second time) and checked for marks again another 4 days later (8 days after bucks were put in with does). The plan was to continue in that pattern until all does were bred. As mentioned above, the plan was to have them all bred within two weeks. I knew that the goats should come into heat within 2-3 days after getting the treatment if they were going to come into heat because of the treatment.

We recorded the does marked each time we checked and followed them through kidding to measure number kidding and number and birth weight of kids. In the group of 11 does that was not treated when the bucks were put in, one doe recycled 28 days after the first breeding, and one doe aborted just prior to kidding due to stress). We measured the cost of treatment by calculating the total cost of each dose ($.80) multiplied by the number of doses given, not counting labor costs.

All does were mated by day 8, indicating that both treatment methods were effective. In addition, treatment timing did not impact the number mated by day 4 (around 15/19 does), number that kidded due to the treatment (18/19 counting the one that aborted), number of kids born (around 1.8 kids per doe), or kid birth weights (around 7.5 lb each). The cost per doe bred was, of course, statistically higher for the does treated when bucks were put in compared to the group that were only given the treatment if they did not cycle within 4 days after the bucks were put in. The overall cost averaged $.90 per doe for group given treatment at the beginning compared to only $.22 per doe for the group that was only given treatment if not bred. However, labor costs were not included and there was not a totally “untreated” group. The extra cost of $.22/doe to get all animals bred within 8 days may not have been needed, though in my mind, it did give more of a “guarantee”.

An interesting note for those of you who don’t think you would like breeding in that short of a time period: after finishing with “synchronized” kidding within a 10-day period because of our 8-day breeding, our farm manager is now a fan of synchronized breeding. This allows for all of the kidding chores, vaccinations, and weaning to be done all at one time, making daily work chores much lighter the other days of the year.

Anthelmintic (Drug) Resistance

Anthelmintic (dewormer/anti-parasitic drug) resistance is a major problem in the small ruminant industry, especially among goat producers. Last summer (2002), studies to determine the extent of anthelmintic resistance were carried out in Maryland, Virginia, and Oklahoma.

Maryland
Two studies were carried out at the University of Maryland Eastern Shore to determine resistance to anthelmintics. Boer crossbred kids (n=27) and Katahdin hair sheep lambs (n=18) were orally treated with 2X the sheep dose of Ivomec, Tramisol, or Valbazen. Fecal egg counts were determined prior to treatment and 7 days after treatment. Ivermectin, Tramisol, and Valbazen treatments reduced fecal egg counts by 95% in only 33.3%, 13.3%, and 40% of the treated animals, respectively. Fecal egg count reduction was not different between species, averaging 66.6% egg reduction. Pre-treatment fecal egg counts were higher for goats than sheep 3,532 epg vs. 190 epg.

In the second study, mature does (n=69, primarily Boer) and ewes (n=47, primarily Katahdin) were orally administered Cydectin or Levasol or 2X the labeled dosage of SafeGuard. Fecal egg counts were determined prior to treatment and 10 days after treatment. Animals with beginning FEC of <50 were excluded from the study. Overall, Cydectin, Levasol, and Safeguard worked effectively (reduced FEC by >95%) in 71.2%, 29.8% and 30.2% of the animals, respectively indicating reduced drug efficacy for all treatments. However, overall percentage egg count reduce was greater for Cydectin (92.7%) than for Levasol (44.5%) or SafeGuard ( 38.3%). Fecal egg count reduction was less for meat goats (23.5%) than hair sheep (63.9%).

For more information about the Maryland studies, contact Dr. Niki Whitley at (410) 651-6194 or nwhitley@mail.umd.edu.

Virginia
Researchers at Virginia State University surveyed sheep and goat producers regarding their management practices and parasite control strategies. As part of their survey, they visited a number of farms (mostly meat goat) and tested for anthelmintic resistance. The products that were tested were fenbendazole (SafeGuard/Panacur), albendazole (Valbazen), levamisole (Levasol/Tramisol), ivermectin (Ivomec), and moxidectin (Cydectin).

All products were administered orally to goats at 1.5 to 3 times the oral dosage for sheep or to sheep at 1 to 1.5 X the labeled dosage. All animals were weighed prior to treatment, so that an accurate dose could be administered. Fecal egg counts were done prior to treatment and 7 to 14 days after treatment. Products which reduced fecal egg counts by 90 percent or more were deemed effective. Products which reduced egg counts from 60 to 90 percent were considered to be moderately effective. At less than 60 percent fecal egg reduction, severe resistance was reported.

Based on these criteria, severe resistance to fenbendazole (at 2X the dose) was found on six of nine Virginia farms. Moderate resistance was found on three additional farms (at 3X the dose). Similarly, albendazole (at 2X the dose) showed only a 40 and 78 percent fecal egg reduction on two Virginia farms. There was severe resistance to ivermectin on 9 of 11 farms (at 2X the dose) and moderate resistance on the two other farms and two additional farms (at 3X the dose). In contrast, levamisole was over 90 percent effective on five of six farms (at 1.5X the dose). Moxidectin was over 90 percent effective on 8 of 11 farms (at 2.5X the dose) and between 73 and 83 percent effective on the other three farms.

It is important to note that the data in Virginia are preliminary and represent a limited number of farms. It was also a drought year in which fecal egg counts were generally lower than average. For more information about the Virginia study or to participate in the study, contact Dr. Joe Tritschler at (804) 524-5957 or jtritsch@vsu.edu.

Oklahoma
In Oklahoma, producers were similarly asked to participate in a survey conducted by researchers at Langston University. As part of the study, 15 goats at each participating farm were treated orally with levamisole, (Tramisol /Levasol), albendazole (Valbazen), or iver-mectin (Ivomec). The animals (mostly Boer and Boer crosses) were weighed at the time of treatment, and individual fecal samples were collected prior to treatment, then one to two weeks later. As compared to the Virginia study, EPG’s were generally higher (>500 EPG), making for a more effective comparison.

As in Virginia, ivermectin and the benzimidazoles were shown to be ineffective in sufficiently reducing fecal egg counts, even at higher doses. Only Moxidectin and Levamisole showed any promise as effective anthelmintics. For more information about the Oklahoma study, contact Dr. Terry Gipson at (405) 466-3836 or tgipson@luresext.edu.

How to Reduce Anthelmintic Resistance

  1. Don’t bring resistance to your farm. Always quarantine new animals, and immediately deworm them with at least two drug classes. Keep them separated, preferably away from any pasture for a few days until no further eggs would be passed in the manure from imported drug resistant parasites.
  2. Do not underdose. Dose for the heaviest animals in your flock or divide them into groups (lambs/kids and adults, for example) and dose for the heaviest weight within each group.
  3. Administer the drugs effectively. Put the drug in the back of the mouth to prevent closure of the esophageal groove and rumen by-pass; drugs are more effective when they go into the rumen.
  4. When giving benzimidazoles, it is better to hold the animals off feed for 12 to 24 hours before treatment. If you suspect that you have resistance to the benzimidazoles, give two doses of the drug separated by 12 hours.
  5. Use combinations of drugs.
  6. Do not use any single drug group for too long. Rotate anthelmintics annually.
  7. Focus treatments on the most susceptible animals: e.g. young stock, first-time mothers, high producers. Leave some animals untreated.

Featured Breed

Kiko: An “All-Around” Meat Goat

The Kiko is one of the newest breeds of goats in the U.S. They are a meat breed that originated in New Zealand when a corporation of large breeders (Goatex Group LCC) began capturing and farming an unselected population of native, feral goats. These goats were subjected to stringent selection criteria. The two main criteria for selection were survivability and weight gain. No shelter was provided to these goats. No assistance was given during kidding. No supplemental feeding was provided. No hooves were trimmed. Minimal parasite control was administered. The animals that performed exceptional were retained, and in 1986, the herd was closed to outside bucks.

The Kiko is a large framed, early maturing goat. They are not as heavy boned as some breeds. Though Kikos may be any color, in the U.S. they are mostly white, because white goats were originally imported. Their coat ranges from slick in summer to flowing hair in winter. The primary characteristic of the Kiko is its hardiness and ability to produce under natural conditions without supplemental feeding. They are best utilized in a crossbreeding program to produce kids for the meat market.

Kiko is a word used by the indigenous people of New Zealand to describe substantial meat producing animals. Prior to leaving New Zealand, all purebred Kikos are fitted with a microchip to safeguard the integrity of the breed.

Texel Lamb Wins Carcass Contest . . . Again!

The Live Animal and Carcass Contest at the Maryland Sheep & Wool Festival recognizes producers of superior meat-type lambs and helps producers correlate live traits (subjective) with carcass traits (objective). The lambs are evaluated on the hoof, prior to processing at Mt. Airy Locker, where actual carcass measurements are obtained.

For the fifth consecutive year, the Live Animal and Carcass Contest was won by Beverly and Sherman Pearsall from Thurmont, Maryland. Their champion lamb was a crossbred Texel ram lamb weighing champion lamb carcass80 pounds. The lamb dressed out an impressive 58 percent, producing a 46 lb. carcass and a a 3.2 square inch loin eye (lamb chop), the largest in the class. The lamb had only 0.17 inches of back fat. The Texel breed is known for its extreme muscling in the leg and loin regions.

The reserve champion carcass lamb was a 107-pound Dorset ram lamb exhibited by Bill and Katie Powers from Townsend, Delaware. This lamb had the highest scoring leg in the class (15/high prime) and only 0.18 of back fat. Its loin eye was 2.8 square inches, the second largest in the class. It is not unusual for Dorset lambs to do well in a carcass contest. Besides being excellent mother sheep, Dorset-sired lambs are thickly muscled. They are the preferred type of lamb in the hothouse lamb trade.

Goat Meat Added to COOL Law

A bill was recently introduced by Congressman Mac Thornberry (R-Texas) to add poultry and goat meat to the new country-of-original labeling (COOL) law. Last year’s Farm Bill included a voluntary provision asking retailers to label certain agricultural commodities with a country of origin. This voluntary provision becomes mandatory Sept. 30, 2004. Under the new country -of-origin law, meat may not be labeled as having a U.S. country-of-origin, unless it is born, raised, fed, slaughtered, and processed in the United States.

The intent of COOL is to provide consumers with information regarding meat origin, which supporters suggest will boost U.S. meat sales. There are two exemptions to COOL. First, COOL doesn’t include covered commodities that are ingredients in processed food products. For example, hamburger on frozen pizzas would be exempted. Second, COOL excludes food service establishments from informing consumers of country-of-origin.


Urinary Calculi (Urolithiasis)

Urinary calculi or “water belly” is a common metabolic disease of male sheep and goats. The disease occurs when calculi (stones), usually comprised of phosphate salts, lodge in the urinary tract and prevent urination. The culprit is diets which are excessive in phosphorus and magnesium and/or have an imbalance of calcium and phosphorus. Lack of water and water sources that are high in minerals also contribute. Animals being fed high concentrate diets are most prone. Wethers are at greatest risk since castration of young males removes the hormonal influence necessary for the penis and urethra to reach full size. In females, calculi are formed, but excreted due to anatomic differences in the male and female urinary tract.

Clinical signs start with restlessness and anxiety. Affected animals may experience abdominal pain, distention and rupture of the urethra, loss of appetite, a humped-up appearance, edema under the belly, urine dribbling, kicking at the belly, straining, and attempts to urinate. In goats, there may be increased vocalization and tail twitching. If left untreated, affected animals will die when the bladder bursts and urine fills the peritoneal cavity.
Treatment of urinary calculi depends upon the location of the obstruction and may be as simple as snipping off the urethral process to allow calculi at the end of the penis to dislodge. Tranquilizers and antispasmodics may help to naturally dislodge calculi. In more advanced cases, surgical intervention may be necessary to save valuable animals or pets. Veterinary advice should be sought when urinary calculi is suspected.

Like most disease conditions, it is better to prevent urinary calculi than to treat it. It can be prevented by feeding rations which contain a calcium-to-phosphorus ratio of at least 2:1. Cereal grains (corn, barley, etc.) have an abnormal calcium-to-phosphorus ratio of 1:4 to 1:6 and need to be balanced with other feeds or mineral sources to form a complete ration. In contrast, legumes (e.g.. alfalfa, clover) have much more calcium than phosphorus.

Adequate water intake is also necessary to prevent urinary calculi. The use of salt (up to 4% of the ration) will help to increase water intake. The use of ammonium chloride at a level of 0.5 percent of the total diet will help to acidify the urine and prevent the formation of calculi. Most commercial lamb and meat goat diets contain ammonium chloride, as well as the proper ratio of Ca:P.

When formulating your own feed rations, you need to include minerals in the ration or a source of calcium (such as legume hay). Free choice minerals may not be adequate to prevent urinary calculi in male goats and sheep, since you do not know if they are consuming sufficient quantities of the mineral.
