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…
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…
Gestation in sheep varies from 142 to 152 days with the average being 147 days. Just like people, individual pregnancies can vary, gestation periods of 138 to 159 days are not unheard of.

The form above calculates the lambing date based on a 147 day gestation period.
