Reproduction

Reproductive efficiency is one of the most important factors affecting profitability in sheep and goat enterprises, though optimal reproductive level varies by production environment and resource availability. On this page, links are arranged alphabetically by subject category: accelerated lambing/kidding, artificial insemination, breeding ewe lambs and doelings, breeding soundness, estrus synchronization, ewe/doe management, flushing, heat detection, libido, management, out-of-season lambing/kidding, parturition, pregnancy diagnosis, ram and buck effect, ram/buck management, reproduction in the female, reproduction in the male, and reproductive technologies.

The Maryland Small Ruminant Page [sheepandgoat.com] was created in 1998 as an information portal for sheep and goat producers and anyone else interested in sheep and goat production and marketing. The web site includes original documents and images as well as a comprehensive list of links pertaining to small ruminants and related topics. The web site was developed and is maintained by Susan Schoenian, Sheep & Goat Specialist at the University of Maryland's Western Maryland Research & Education Center. Susan has been with University of Maryland Extension since 1988. She holds B.S. and M.S. degrees in Animal Science from Virginia Tech and Montana State University, respectively, and also attended The Ohio State University. Susan conducts the Western Maryland Pasture-Based Meat Goat Performance Test at her research facility in Keedysville. She raises Katahdin sheep on her small farm called The Baalands in Clear Spring, Maryland. Please direct all questions, comments, or suggestions to Susan at sschoen@umd.edu.
