Project Information

Abstract:

The first buck test in Mississippi was developed in Greene County, under real commercial farm conditions. In the 2023 test, 45 farmers from 14 states took part, consigning a total of 89 in the test. For current goat farmers in the southeast and for those wanting to come into the goat business, buck tests give them the possibility of buying animals that adapt and perform better in their conditions, which makes their business more sustainable for the southeast. The objectives of the test are:

  1. Identify meat goat genetics with resistance/resilience to the stresses present in the Southeast, including internal parasites, high temperatures, and the utilization of native vegetation and commonly planted forages.
  2. Identify meat goat genetics that most efficiently convert pasture to a salable carcass.
  3. Based upon polling of producers and input from industry experts, incorporate additional studies in future tests that will provide meaningful data for producers to improve their production efficiency and profitability.

By applying to this grant, we want to ensure funds for developing 2 more years of Buck tests in MS to increase the sustainability of the business, and revenue of farmers, and improve their quality of life.

Project Objectives:

The test will consist of 100 to 200 bucks in year 1, dependent on forage conditions, with adjustment in later tests based upon test site conditions.  The test site will be White Sands Research Center in MS.  Bucks for year 1 will be limited to purebred or 100% Kiko, born between December 15 and March 1 of the test year.  Beginning in year 2, the age range of consignments may be adjusted to lessen the variable of age differences during the test or to include an additional opportunity to consign.  The kidding window will be determined by polling so that as many producers as possible can participate in the test.  Two bucks per farmer unless all slots are not filled, in which case additional bucks can be added per farmer at the discretion of MSSTATE.  MSSTATE will determine the order in which to increase the number of consignments.  Bucks must be a minimum of 40 pounds with a 2% allowance for bucks traveling in from out of State.  The animals must have a Scrapie tag and a certificate of health from their veterinarian. The bucks must be weaned at least 2 weeks prior to the test, vaccinated for CDT, and pneumonia (Pasteurella multocida), and have one hoof trim.  Bucks will be required to have identified sire and dam, birth date, birth weight, and weaning weight.  Nominations will be open from April 15 – May 15. Funds will be used to cover farm labor, feed, hay and any necessary treatments.  Upon check-in, the bucks will be given an exam by a veterinarian, with any buck showing signs of communicable diseases being disqualified. The bucks will receive a tag with their test id, an initial health check-up, and a deworming with 3 classes of dewormer (Valbazen, Ivermectin, and Levamisole). They will also be orally drenched with a coccidiostat, given a shot of oxytetracycline for shipping fever prevention, and given a zinc sulfate solution hoof bath.  A blood sample of 0.5 cc will be drawn at check-in to determine PVC and preserved for future genome projects.  A fecal sample will be collected prior to deworming.  The use of copper bolus and hormone implants is strictly prohibited.  A two-week warm-up period will take place in the quarantine lot beginning June 25.  During this warm-up period, the animals will be fed a diet consisting of quality hay and commercial 16% goat pellets.  Bucks that show signs of having anthelmintic-resistant parasites (as determined by the FEC reduction test 10-14 days following initial deworming) will be disqualified. Isolation to the dry lot areas during warmup will allow the identification of anthelmintic-resistant parasites prior to the forage test, thus preventing the spread of those parasites to the forage test plots.  Animals with external abscesses will be isolated and disqualified from the test.  The forage test will be 84 days beginning July 9.  The forage test will be conducted on approximately 30 acres consisting of 3 forage plots and a handling facility.  The forage plots in year 1 will consist of warm-weather grasses commonly grown in the Southeast, including Bahia, Bermuda, and other forages as determined by the University Forage Specialist. The animals will have access to Sweetlix Meatmaker 16:8 Mineral or equivalent for the duration of the test. Prior to the forage test, samples will be tested from forage plots to determine parasite load for informational purposes.  During the forage test, the rotation will be approximately every 14 days, or as deemed necessary.  The bucks will be checked approximately every two weeks during the forage test and adjustment period.  Checkups will include Weight, ADG, FEC, FAMACHA, and BCS.  The animals will have an SC measurement, REA, and USDA Grading taken at the start and finish of the test.

Bucks that have a BCS of 1.5 AND an FEC of >2500 epg will be dewormed.

Bucks with a FAMACHA of 4 AND an FEC of >2500 epg will be dewormed.

Any animal that is dewormed will be disqualified from ranking in the final ranking. At the conclusion of the test, bucks will be dewormed if the farmer chooses, which will avoid withdrawal time complications for those bucks destined for slaughter.  Animals that are disqualified after drop off, for any reason, will be held for a two-week period to allow producers the opportunity to pick the animal up. After two weeks, any disqualified animals being held will be liquidated to a local livestock market unless other arrangements have been made with MSSTATE.

BIOSECURITY MEASURES

A clean needle will be used for each animal when giving shots.  The herd will be checked daily by trained personnel for early detection of illness including internal parasites.  Visitor access to barns and pastures will be restricted for the duration of the test.  Farmers who wish to visit the site during the test may contact MSSTATE to request an appointment and will be issued disposable shoe covers and escorted to the site.  Vehicle traffic at test sites is prohibited during tests.  Animals that display signs of sore mouth or pink eye will be removed from the test site and placed in a quarantine pen for treatment and fed individually, returning to the test site after the condition is cured.  Feed, hay, and minerals will be provided in troughs or racks.  Animals with signs of CL abscesses will be withdrawn from the test.  Pens, working facilities, tools and utensils, waterers, and service vehicles will be disinfected with potent disinfectant.  In case of death, the farmer will be given the option to have a necropsy conducted at their expense.

Research

Materials and methods:

Kikos are a meat goat breed that is growing in popularity in the Southeast because of their hardiness and resistance to parasites. The objective of this test was to collect data on weaned Kiko bucks grazing a mixture of warm season forages (Crabgrass (Digitaria sanguinalis), Switchgrass (Panicum virgatum), Bahia grass (Paspalum notatum), Carpet grass (Axonopus affinis), Dallisgrass (Paspalum dilatatum), under commercial farm conditions in Mississippi (MS), from June 2024 to August 2024 (IACUC-24-232). Thirty-five (35) farmers consigned 66 bucks from 13 different states (TX, OK, AR, MO, IL, IN, KY, TN, MS, AL, GA, NC, and WV). Measurements including body weight for calculating the average daily gain (ADG), body condition scoring (BCS), FAMACHA©, and fecal egg count of nematodes (FEC expressed in eggs per gram of feces-EPG), and coccidias (OPG, oocysts per gram of feces) were taken every two weeks. Loin eye area (LA) and loin depth were measured via ultrasound at the beginning and end of the grazing period. USDA grading was also performed by observation of the animals at the same time points. The LA was used to calculate the ratio of LA/BW (REA). The herd was rotated between three paddocks every two weeks, and forage samples were obtained from each paddock for analysis prior to the test. The average crude protein and fiber (acid detergent fiber) of the grasses were 10.55% and 41.23%, respectively. The bucks were dewormed with three classes of anthelmintics upon arrival at the testing site. The 10-week grazing period started after a two-week quarantine period was completed after deworming.

Research results and discussion:

The data was analyzed using a Proc Mixed Analysis (SAS, 9.4) to check the effect of the variable (FAMACHA©, BCS, FEC) on BW for a total of 183 observations. The overall averages for the variables resulted: BW 24.7± 4.6 kg; ADG 19.4 g/d; FAMACHA© 2.5; BCS 2.4; and nematodes 1291.2 EPG. FAMACHA© did not affect BW (P=0.5651); BCS affected BW (P<0.0001), and higher BCS values were associated with higher BW of the bucks. FEC did not affect BW (P=0.8974). Winning bucks had ADG (g/day) of 58.3 (KY), 51.8 (MS), and 51.8 (GA). Winners for FEC (EPG) had 233.3 (KY), 250 (TN), and 283.3 (KY). The average REA/BW ratio was 1.542 (KY), 1.539 (MS), and 1.506 (IN) for the winning bucks. The overall winning buck was from MS. In 2024, MS experienced a very harsh summer with little rain and low grass availability, restricting the animals' normal growth. In the future, a small commercial concentrate supplementation (approx. 250 g/animal/day) will be used to help the animal express its growth potential.

Most goat meat sold in the U.S. is imported, but a group of Mississippi meat goat producers wants to see that change.

The Southeastern Buck Performance Test aims to improve the profitability of the meat goat industry in the region by improving meat goat genetics.

The Aim is to help current and prospective Mississippi producers improve their herds and, as a result, create a strong market for their products.

 

Most of the goat meat we eat in the U.S. comes from abroad with this test, we will hopefully be able to one day help meet the demand for goat meat in the U.S. with a domestic product.

More people coming into this business will have a place for whatever product they produce -- meat, special cuts, patties, sausages, jerky, etc.”

The test has three primary goals: to help identify genetics that produce a salable carcass by feeding forages commonly available in the region; to help improve resistance to internal parasites, which is the number one challenge for goat producers in Mississippi; and to determine what studies should be included in future tests that can help producers improve production efficiency and profitability.

Studying the performance of bucks in real farming conditions is the only way to improve the breed in local conditions and stop depending on imported semen to improve performance.

“These are the four factors that drive profit for producers:

  1. Having a healthy animal and parasite resistance is one of the most important issues
  2. An animal that can reach the proper weight and muscle to get a USDA prime grading.
  3. An animal that is able to graze and grow under MS conditions.
  4. Be able to make meat goats a more feasible livestock animal for small farmers.
