Zactran® Eliminates Footrot

Gamithromycin (Zactran®) is macrolide antibiotic licensed for cattle in the treatment and control of bovine respiratory disease. It is not approved for sheep (or goats); however, it may be prescribed by a veterinary for extra-label use.

Foot rot is caused by the anaerobic bacterium Dichelobacter nodosus. D. nodosus does not survive for long in the environment, so the main reservoir of infection is in the animals. In theory, foot rot can be eliminated from a flock, through a combination of vaccination and/or antibacterial treatment (parenteral or topical) and/or culling of infected animals, coupled with good biosecurity.

In a German flock with a high prevalence of foot rot, 184 sheep were given the standard dose of Zactran® (6 mg/kg). The injection was given subcutaneously in the axilla. On day 23, 19 sheep were re-treated with Zactran®. On day 45, no lame sheep or positive lesion scores were observed.

In a Danish study, 48 flocks comprising around 9000 sheep were given the standard dose of Zactran®, subcutaneously on the side of the neck. Of the 48 participating flocks, 44 remained free of foot rot and D. nodosus more than one year later

The results from both studies showed that whole-flock, systemic antibiotic treatment can eliminate foot rot and D.  nodosus. In the Danish study, a single treatment with gamithromycin was sufficient. In the German flock, two treatments at an interval of 22 days were required to eliminate foot rot in some sheep.

A Wise Man's Alfalfa

by Dr. Tom Terrill
Fort Valley State University


Because of its ability to tolerate infertile, acidic soils and grow well on sloping land with minimal lime and fertilizer inputs, the perennial warm-season legume sericea lespedeza (SL; Lespedeza cuneata) has earned the nickname "Poor man’s alfalfa." With recent research on the potential health and environmental benefits of including SL in the diet of ruminant animals, it may be time for a new nickname:  "wise man's alfalfa."

Dr. Tom Terrill
Like other forages that contain condensed tannins (CT), a compound that binds to protein when the plant is chewed and digested, SL is non-bloating. It also lowers the production of methane from the animal’s rumen, reducing the contribution of this powerful greenhouse gas to global warming.

However, for farmers trying to keep their livestock healthy during a period when anthelmintic drugs are rapidly losing their effectiveness, the excellent anti-parasitic properties of SL in fresh (grazed) or dried (hay, leaf meal, pellets) forms in the diet of sheep, goats, and other ruminants may be most important.

2015 Maryland Buck Test

Several changes will be implemented for the 2015 Western Maryland Pasture-Based Meat Goat Performance Test. The purpose of the changes is to get better growth rates (ADG) and produce a bigger (heavier) buck at the end of the test, while still being able to effectively evaluate the bucks for parasite resistance and resilience.

The test will start and end later. Bucks should be delivered to the test site on Friday, June 26. The goats will have a 13-day adjustment period. Starting weights will be recorded on July 9 and 10. The later starting date will allow the goats to graze the warm season annual grasses and legumes upon arrival. The test will last for 84 days. Midway through the test, the goats will be switched to the cool season grass paddocks. Final data will be collected on October 1.

The test bucks will be supplemented with soybean hulls throughout the test. Supplementation will begin during the adjustment period and will be gradually increased until it reaches 0.75 lbs. per day or approximately 1.5 percent of  body weight. Data from last year's test showed that the goats' pasture diet was deficient in energy.

You can use the test data to select a parasite-resistant buck.
















The 10 top-performing bucks will be recognized.  As in previous years, the primary performance criteria will be growth (ADG), parasite resistance (fecal egg counts), and parasite resilience (FAMACHA© scores and anthelmintic treatments).  Other criteria will include WDA, ultrasound data, scrotal circumference, teat structure, and hoof structure.

The nomination period for the 2015 test will be April 15 through June 1. Eligible bucks must be born between January 1 and March 15, 2015, and weigh a minimum of 40 lbs. Any breed or breed cross is eligible, with our without registration eligibility. A farm may consign up to five goats to the test.  A maximum of 80 goats will be accepted for the 2015 test.

The total fee for testing a buck will be $120, which includes a $20/head nomination fee. Discounted fees will be offered to Maryland residents and consignors who consign five half-sibs (bucks with same sire) or whose herds are enrolled in the National Sheep Improvement Program (NSIP), a quantitative genetic evaluation program that calculates EBVs (estimated breeding values) for and meat goats (and sheep)..

2015 will be the 10th year of the Western Maryland Pasture-Based Meat Goat Performance Test, which is conducted at the University of Maryland's Western Maryland Research & Education Center in Keedysville. Please direct any questions about the 2015 test to Susan Schoenian at (301) 432-2767 x343 or sschoen@umd.edu.

"Silver Bullet" of Worm Control

by Paul Casey
Heifer Project International

I manage a 60 ewe sheep flock at Heifer Project International’s Ranch in Perryville, Arkansas. About 10 years ago, we started looking at alternative methods of controlling gastrointestinal parasites in sheep. We tried garlic juice, papaya seeds, pumpkin seeds, an herbal dewormer, grazing chicory, grazing sun hemp, and intensive rotational grazing. In the end, rotational grazing was the only practice we kept.

Sheep flock at Heifer Project International
We implemented stringent culling and rotational grazing at the same time and within a few years parasite problems in the ewes were nearly non-existent. While I know that our strict ewe culling and ewe lamb selection helped reduce our worm problems, I believe the grazing is what made it successful.

By controlling what the sheep eat, when they eat it, and how long they are on a given section of pasture, the manager controls forage intake, forage quality, plant regrowth, and relative ingestion of parasite larvae. Grazing management is the most powerful tool we have for maintaining animal health and performance.

Dock Length Has No Effect on Rectal Prolapse

At Texas Tech, researchers investigated the effects of sex, breed, docked tail length, and the expression of the callipyge phenotype on the incidence of rectal prolapse in lambs.

To test whether these factors influence rectal prolapse in a controlled feedlot environment, lambs (n = 382) representing both sexes and four breed types were assigned randomly to one of three docking treatments. In short-docked lambs, the tail was removed as close to the body as possible. In medium-docked lambs, the tail was removed midway between the attachment of the tail to the body and the caudal folds to the tail. Long-docked lambs had their tails removed at the attachment of the caudal folds to the tail.

Incorporating the callipyge phenotype into the study design assessed the effect of enhanced muscle development on rectal prolapse. The overall incidence of rectal prolapse in the study was 2.1 percent. Ewe lambs were no more likely to experience prolapses than male lambs. Seven of the eight (87 percent) lambs that prolapsed were hair sheep. No lambs expressing the callipyge phenotype prolapsed. There was no difference in rectal prolapse occurrence among the three docking treatments.

In the study, sex, tail dock length, and muscling did not appear to contribute to rectal prolapse in lambs. However, there may be an over-looked genetic component that influences the occurrence of prolapses in response to the practice of docking.

Effects of Preslaughter Diet Management

Researchers at Fort Valley State University (in Georgia) used 16 crossbred goats and wether sheep to investigate the effect of preslaughter diet management on physiological responses and microbial loads on skin and carcass.

Experimental animals were fed either a hay or concentrate diet for 4 days and then deprived of feed for either 12 or 24 hours prior to slaughter. Blood samples were collected to measure physiological responses. pH was measured in the Longisimuss dorsi muscle. Skin and carcass swabs were obtained to access microbial loads.

Skin swab samples collected from the sheep showed higher bacterial counts than goats. Behavior observations may have accounted for the difference, as sheep tended to spend more time lying down. Sheep fleece may also be responsible for picking up more fecal material in the holding pen. However, diet and feed deprivation did not influence skin contamination. Diet, species, and feed-deprivation also had no effect on E. coli and total coliform counts in carcass swabs.

Access full article from J. of Animal Science and Biotechnology

Other research regarding the effect of diet on bacterial loads has been contradictory. A 1998 Cornell University study demonstrated that cattle fed grain had much higher coliform and E. coli counts than cattle fed forage diets. The reverse was observed in a 1997 study at the University of Idaho, as artificially-innoculated sheep fed grass hay shed more E. coli and for a longer period of time than sheep fed a concentrate diet.

Maryland's Beginning Farmer Program

University of Maryland Extension is proud to provide the Beginning Farmer Success program across the state. The Beginning Farmer Success program is targeted towards those who have been involved in agriculture for ten years or less. Special focus is paid to helping potential and new farmers establish business plans, scaling up their operations, and making smart production decisions for both crops and livestock.

Hannah Shear
These important topics are taught through workshops, conferences, and hands-on mentorships supported by the University of Maryland Extension, the Southern Maryland Agriculture Development Commission (SMADC), University of Maryland Eastern Shores (UMES), and Future Harvest.

In August, the Beginning Farmer Success Team welcomed Hannah Shear to the group to serve as program coordinator. Hannah was born and raised in Kentucky on a family farm that focused primarily on beef cattle and burley tobacco.Throughout her childhood she was surrounded by the rolling bluegrass pastures of central-eastern Kentucky. This access to plentiful pasture and a love for all things livestock led to Hannah’s desire to raise sheep.

If you have been farming for ten years or less and are interested in being a part of the Beginning Farmer Success Program you should sign-up and check out their website: http://extension.umd.edu/newfarmer.
