Composite Fecal Sampling

One of the methods for determining anthelmintic (dewormer) resistance is the Fecal Egg Count Reduction Test (FECRT). Fecal samples from individual animals are compared before or after treatment or to a control group after treatment. It is recommended that at least 15 animals be sampled.

As an alternative to individual fecal samples, researchers at the University of Georgia compared using pooled composite samples with individual samples. The results of their research were recently published in the Journal of Veterinary Parasitology, "Using composite fecal samples when testing for anthelmintic resistance in gastrointestinal nematodes of cattle."

Their research showed the mean fecal egg counts from the composite and individual fecal samples to be 98.9% in agreement. The fecal egg count reduction of the composite and individual samples was 95.9% in agreement.

The researchers concluded that composite sampling is a practical tool for producers to assess resistance and that is should improve parasitological testing among producers. Methods of composite sampling are discussed in the article.

Worms Kill 87,000 goats in 2015

According to a recent USDA report, "Goat and Kid Predator and Nonpredator Death Loss inthe United States," about 500,000 adult and kid goats were lost to all causes (nonpredator and predator) in the United States (in 2015), which represented 9.8 percent of U.S. adult goat inventory and 19.4 percent of kids born in 2015.

Nonpredator causes accounted for about three-fourths of all adult goat and kid death losses in the United States in 2015. Undetermined causes (found dead or unknown) accounted for the highest number of nonpredator losses in both goats and kids. Of known losses due to nonpredator causes, internal parasites were the primary cause of loss, resulting in almost 87,000 goat and kid deaths in 2015.

Internal parasites accounted for 22.7 percent of all known death losses:  24.8% of goats, 15.6% of pre-weaned kids, 37.7% of post-weaned kids, and 21.5% of all kids. Some of the unknown (found dead) death losses may also have been the result of internal parasites.

Reducing Worm Larvae With Liquid N

As it is well-known, barber pole larvae show increased resistance to commercial anthelmintics drenched to small ruminant livestock, and producers are looking for other alternatives. What about bypassing the livestock entirely and applying a larvicidal product directly on the pasture itself?  Laboratory studies we conducted at North Carolina State University showed that 96.6% L3 barber pole larvae were not moving or dead when immersed in solutions of liquid nitrogen fertilizer.  

So, could we pop two balloons with one dart by fertilizing pastures with liquid nitrogen fertilizer to promote forage growth and at the same time reducing pasture nematode larvae population, their subsequent ingestion by grazing animals and ultimately reducing gastrointestinal parasite loads? North Carolina State University conducted three experiments to test this hypothesis on predominantly tall fescue pastures.

Kiko and Spanish Does Should be Preferred

Researchers at Tennessee State University evaluated health and reproductive traits of Boer, Kiko, Spanish, and Myotonic  does. The Myotonic, a heritage breed, was previously lacking in comparative assessment.

Kiko doe with twins
In the study, Boer (n=73), Kiko (n=115), Myotonic (n=80), and Spanish (n=114) meat goat does were compared for traits associated with health and reproduction. The herd was semi-intensively managed on humid subtropical pasture for 6 years. The study included 838 matings and over 2,000 records for body weight (BW), fecal egg count (FEC), and packed cell volume (PCV).

Boer and Kiko does had heavier BW than Spanish does, which were heavier than Mytonic does.  Myotonic does had lower FEC than Boer does; Kiko and Spanish were intermediate. Kiko, Myotonic, and Spanish does had higher PVC than Boer does. Annual kidding rates, weaning rates, doe retention rates, and kid crop weaned were greater for Kiko and Spanish does than for Boer does, whereas Myotonic does were intermediate.

The results suggest that Kiko and Spanish does should be preferred over Boer and Myotonic does for sustainable meat goat doe performance under limited-input management conditions. Myotonic does maintained the lowest FEC among all doe breeds and warrant further evaluation as a genetic resource for controlling gastrointestinal parasitism.

DUP has no effect during periparturient period

Ewes experience a temporary decline in resistance to gastrointestinal nematodes (GIN) during the periparturient period, characterized by a rise in fecal egg count (FEC) that represents a major source of pasture contamination for naïve progeny. The aim of an Irish study was to assess the effect of level of supplementation with digestible undegraded protein (DUP) during the last 6 weeks of pregnancy on periparturient FEC and the performance of ewes with a naturally acquired parasite infection.

Periparturient ewes
Eighty-five Belclare and Belclare x Scottish Blackface twin/triplet-bearing ewes were allocated to 1 of 4 dietary groups representing the combination of 2 concentrates (DUP concentration 29 and 94 g/kg dry matter) with 2 levels of concentrate during the final 6 weeks of gestation. All ewes were housed during the pre-partum feeding period and offered grass silage ad libitum.  After lambing, ewes and lambs grazed on permanent sheep pasture, without concentrate supplementation, until weaning (14 weeks post lambing).

The effect of week (relative to lambing date) on FEC was highly significant. However, diet did not influence FEC at any stage either pre- or post-partum.  The changes in BW and BCS from 6 weeks before lambing to weaning were not affected by the concentration of DUP in the supplement, but ewes on treatments involving the higher level of supplementation lost less BW and BCS.

The results of this study indicate that the level of DUP supplementation during the last 6 weeks of pregnancy does not affect FEC, BW or BCS of housed ewes with a naturally acquired GIN infection.

2017 Junior Sheep & Goat Skillathon

The 2017 Junior Sheep & Goat Skillathon will be held Sunday, May 7 at the Maryland Sheep & Wool Festival. The festival is always held the first full weekend in May at the Howard County  Fairgrounds in West Friendship. For the first time, there will be an admission fee for adults ($5).  Everyone under 18 enters for free. Parking remains free.

A skillathon provides youth with the opportunity to blend knowledge and skills acquired in livestock judging, demonstrations, and care and exhibition of animals into a single activity. It consists of a series of stations where youth are tested on their knowledge and abilities related to livestock. In the Sheep & Goat Skillathon, all stations pertain to sheep and goats (meat, milk, and fiber).

Fleece judging is always one of the stations.

The Junior Sheep & Goat Skillathon is open to any youth between the ages of 8 and 18. Individuals and teams (of 3 or 4) from any county, state, or province may compete. Youth compete according to their age as of January 1st of the current year. Youth ages 8 to 10 compete as juniors; youth ages 11 to 13 compete as intermediates; and youth 14 to 18 compete as seniors.

Questions pertaining to this year's skillathon should be directed to Christopher Anderson, 4-H Youth Development Specialist, Animal Science, University of Maryland Extension, Maryland 4-H Center, 8020 Greenmead Drive, College Park, MD 20740, phone: (301) 314-7187, fax: (301) 314-7146 or canders2@umd.edu.

No Maryland Wool Pool in 2017

After 59 years of operation, there will be no Maryland Wool Pool in 2017.  For many years, the wool pool has provided a market outlet for fleeces. The pool has been especially beneficial for small producers.

There have been many managers of the Maryland Wool Pool. Prices always seemed to be higher than other pools, with similar types of wool. The Maryland pool was always innovative in its approaches to marketing wool, instituting classing and baling. In fact, the Maryland Wool Pool hosted many ASI classing schools.


In its next newsletter, the Maryland Sheep Producers Association will offer alternatives for marketing wool. There are still wool pools in neighboring states:  Virginia, West Virginia, and Pennsylvania. Some shearers will purchase wool.

Many producers direct market their wool to hand spinners. Others add value to their wool and sell roving, top, yarn, or finished products. You can take wool to landfills. Many producers have switched to hair sheep, so they don't have to worry about shearing and marketing wool.

Upcoming Webinar: Dairy Sheep

"Is Sheep Milk Production in Your Future" is the title of an upcoming webinar on March 14, 2017, at 8 p.m. EST. The presenter is Dr. Dave Thomas, Professor of Sheep Management and Genetics from the University of Wisconsin (retired). The host is Jay Parsons from Optimal Ag. The sponsor is ASI's Let's Grow Program.

Milking sheep in Maryland
The U.S. is the leading importing of sheep milk cheeses in the world with over half of all world trade in sheep milk cheeses coming to the U.S. Some common imported 100% sheep milk cheeses are Manchego from Spain, Pecorino-Romano from Italy, and Roquefort from France.

Therefore, it would seem that there is ample opportunity for the development of a dairy sheep industry in the U.S. for the production of domestic cheeses to compete with this large influx of imported sheep milk cheeses.

However, nothing is ever as simple as it looks. This webinar will discuss the things that are necessary to produce sheep milk efficiently .
