Top performing bucks in 2009 test

The top-performing buck in the 2009 Western Maryland Pasture-Based Meat Goat Performance Test was a purebred Kiko buck consigned by Craig Adams from Litchfield, Illinois.  A first-time consigner to the Maryland test, Adams had four of the top bucks in the test.  He was the test's top consigner.

John Smith from Petersburg, Virginia, the consigner of last year’s top buck, had three of the top bucks in the 2009 test. He was in close contention for top consignment (top 3 buck) honors.

Sixty bucks participated in the 2009 Test. They were consigned by 17 breeders from 11 states. Breed breakdown was 46 New Zealand, purebred, or percentage Kikos, 5 Kiko x Boer crosses, 6 fullblood and percentage Boers, 2 Composite Tennessee Mountain Meat Goats  (Boer x Kiko x Spanish), and 1 Myotonic.

The Western Maryland Pasture-Based Meat Goat Performance Test was initated in 2006 at the University of Maryland's Western Maryland Research & Education Center in Keedysville, MD. The purpose of the test is to evaluate the performance of meat goats consuming a pasture-only diet, with natural exposure to internal parasites. While on test, the bucks are evaluated for growth, parasite resistance, parasite resilience, and carcass merit.  This was the first year that any bucks were harvested to collect actual carcass data.


Performance

The 2009 test lasted 100 days, from June 18 until September 26. There was a 12-day adjustment period. Starting weights ranged from 25 to 69 lbs. and averaged 48.1 lbs. Ending weights ranged from 38 to 83 lbs. and averaged 61.9 lbs. Average daily gains ranged from -0.03 to 0.28 lbs. per day and averaged 0.14 lbs. per day. The buck with the highest average daily gain was a crossbred Kiko buck consigned by Merritt Burke from Nassau, Delaware.

Internal parasites (worms) were not a significant problem in this year's test.   Fecal egg counts did not get high until towards the end of the test in late-September. The buck with the lowest average fecal egg counts was a percentage Boer consigned by Aaron and Levi Lantz from Oakland, Maryland. During the duration of the test, Hamonchus contortus (the barber pole worm) comprised more than 80 percent of the worm infection, almost 100 percent of the infection in August and September.

Only 11 anthelmintic treatments were administered to the bucks after the initial double deworming at the start of the test. The buck with the lowest average FAMACHA© scores was a Kiko buck consigned by Kendell and Dana Barnes from  Winchester, Kentucky. It has a FAMACHA© score of 1 each time it was checked. The Barneses were the top consigner in last year's test.

Bucks meeting gold, silver, and bronze standards of performance for growth, parasite resistance, and parasite resilience and minimum standards for structural correctness and reproductive soundness were deemed the top-performing bucks in the test eligible to sell via auction. Eleven bucks qualified.

Western Maryland Field Day & Sale

Nine
bucks sold via silent auction on October 3rd at the 2nd annual Western Maryland Goat Sale & Field Day. Prices ranged from $200 to $1050 and averaged $514. The bucks meeting the Gold standards of performance sold for $750 and $825, respectively.

The sale also included an invitation doe sale. Consigners to the buck test were eligible to consign does to the sale. Nineteen Kiko and Boer does sold for an average price of $269.  The high-selling doe was a Kiko consigned by John Smith.  It brought $575. A silent auction proved to be a good method to sell the goats. It put more emphasis on performance and allowed buyers to make more thoughtful purchases.

Dr. Richard Browning, a Research Animal Scientist from Tennessee State University, was the featured speaker at the field day. Dr. Browning discussed his multi-year meat goat breed comparision study and on-farm performance testing. The event hosted the first Goat Skillathon for youth. Twenty-eight youth competed for top honors.


Carcass evaluation

Nine bucks were chosen for harvest.  They were processed on October 15 by LambCo, LLC in New Windsor, Maryland.  Live weights (LW) ranged from 62 to 86 lbs. and averaged 72 lbs. Dressing percentages (DP) were in the expected range for pasture-raised goats. They varied from 38.8 to 49.2 percent and averaged 43.1 percent.

Rib eye area (REA) ranged from 1.45 to 2.2 square inches and averaged 1.79 square inches. The goat with the biggest rib eye was a 79-lb. crossbred Kiko buck consigned by Merritt Burke of Nassau, Delaware. It was also the top-gaining buck in the test.

The carcasses were completely deboned to determine yields. As a percentage of carcass weight, lean yield ranged from 57.2 to 65.5 percent and averaged 60.9 percent.  As a percentage of live weight, lean yield ranged from 21.5 to 30.7 percent and averaged  25.4 percent. The highest yielding goat was a purebred Kiko consigned by Craig Adams.

Next year, we would like to harvest more goats from the test and perhaps incorporate a carcass contest into the performance testing program. Additional funding will be required for the carcass evaluation, especially if more goats are evaluated.

The Western Maryland Pasture-Based Meat Goat Performance Testing Program Committee consists of Susan Schoenian, Jeff Semler, David Gordon, Mary Beth Bennett, Willie Lantz, E. Nelson Escobar, M. Scott Updike, and Shannon Uzelac. Dr. Kevin Pelzer from the Virginia-Maryland Regional College of Veterinary Medicine serves as the consulting veterinarian.
