Ec97-274 Management Of Replacement Gilts For Efficient Reproduction, Donald G. Levis
Ec97-274 Management Of Replacement Gilts For Efficient Reproduction, Donald G. Levis
University of Nebraska-Lincoln Extension: Historical Materials
Successfully introducing replacement gilts into the breeding herd is an important aspect of breeding herd efficiency. To attain herd efficiency, females must ovulate adequate numbers of viable ova, express estrus, show willingness to mate and conceive in a regular manner. If these qualities are properly developed, pregnancy rate and litter size will be maximized. A gilt development and management program needs to be designed for gilts from birth to farrowing their first litter.

G97-1324 Beef Cattle Implant Update, Dicky D. Griffin, Terry L. Mader
University of Nebraska-Lincoln Extension: Historical Materials
This NebGuide discusses the mechanism of action and use strategies for growth promoting implants, including expected responses and cost analysis.
Introduction
Growth promoting implants have been used extensively in beef production for over 30 years. Significant changes in implants and implanting strategies have occurred. Prior to 1987, available implants were estrogenic agents which metabolically enhanced nutrient use to enhance growth. These products improved feed efficiency 5-10 percent and daily gains from 5-15 percent. In 1987, the androgenic (tissue building) agent, trenbolone acetate, was approved for use in growth promoting implants. This compound had an additive effect with existing estrogenic implants. …
