Katahdins are raised in diverse environments using a wide range of management styles and for a variety of reasons. However, there should be a few common goals in any flock. In addition to being a shedding hair breed, Katahdins have always been viewed as an easy keeping maternal breed. In recent years, many breeders have also begun selecting for parasite resistance to make the breed even more easy keeping. We know that the number one predictor of profitability in a ewe flock is the "Pounds of Lamb Weaned per Ewe Exposed." This metric combines several maternal traits. This article will…

Selecting for Parasite Resistant Katahdins

People frequently ask us for suggestions on improving the parasite resistance of their flocks and how to identify resistant animals, and with good reason. Intestinal worms, or parasites, are one of the most limiting factors to profitable production for shepherds raising sheep on pasture. Lambs and late gestation and lactating ewes are the most susceptible. The main parasite of concern in much of the U.S. is Haemonchus contortus or barber pole worm. The most obvious cost to producers is through deaths of lambs and ewes. But probably more loss occurs in lambs because of anemia, reduced appetite, slower growth, delays…

Drug Withdrawal Times for Sheep

Whenever we sell animals, be it at auction, privately as feeder lambs, breeding stock or even just pets and lawnmowers it is our responsibility to make sure that the animals we are selling will not enter the food chain with illegal drug residues in their tissue. Animals that are sold at auction need to be ready to slaughter as many enter the food chain within hours or days after being sold. Private sale feeder lambs, pets and breeding stock animals can be sold before their drug withdrawal times are over as long as you tell the buyer and they are…

Data collection is the cornerstone of obtaining Estimated Breeding Values (EBVs) through the National Sheep Improvement Program (NSIP). But the need for good records and accurate data is not limited to producers submitting data to NSIP. All flocks can benefit from good data collection since selection and culling decisions should be based on measured production criteria. Those considering joining NSIP at some point, will find collecting accurate data from the start will be helpful. There are many excellent resources (see Resources below) that describe the individual traits and/or give detailed instructions for entering the data into Pedigree Master. This document…

To best express their genetic potential, sheep must be in optimal body condition. Both overly fat sheep and sheep that are too thin are not as productive as they can potentially be. Body condition scoring (BCS) enables you to identify the animals that fall outside of a preferred range. You can use this information to evaluate feeding strategies and to identify animals that are not doing well in your management system. This article will cover the use of BCS as a management tool. Links to information on how to perform BCS can be found in the reference section at the…

NSIP – What Is in It for Me?

For most of us, raising sheep is a business. All successful businesses continually and objectively evaluate their products for performance, accuracy, and predictability. Estimated Breeding Values (EBVs) as provided by the National Sheep Improvement Program (NSIP), allow shepherds to convert performance records for economically important traits into information about an animal's genetic merit while increasing accuracy and predictability for those traits. EBVs provide a science-based selection tool to improve or enhance preferred traits but do not take the place of direct evaluation of an animal's physical appearance, health, or structural correctness. There are multiple ways to use the power of…
