The heifer enterprise of a modern dairy operation plays a crucial role in health and productivity performance, cost of production and future potential. The variables that determine heifer inventory are nearly innumerable, but at minimum, reproductive performance in the cow and heifer herd, semen selection, morbidity and mortality in the heifers ...

Heifer disposition and bonding of lambs to heifers
Applied Animal Behaviour Science, 1987Abstract Abusive and non-abusive (tolerant) heifers were individually identified during pen confinement with young sheep. Physical aggression by abusive heifers toward lambs included butting and kicking. Two groups of three 75-day-old lambs confined with tolerant heifers developed a bond after 20 days and a strong bond after 55 days.

Replacement heifer development is a critically important area for veterinarians to offer production medicine advice to their beef-producing clients. Productivity for beef cattle herds has been shown to increase when a high percentage of heifers become pregnant early in the first breeding season.55 A producer's heifer development program should result ...

The purpose of this paper is to provide practicing veterinarians a recommended procedure for determining their clients' cost of raising replacement heifers. With these costs in mind, practicing veterinarians can play a major role in helping beef cow operators make profitable replacement heifer decisions.

Developing replacement beef heifers
Theriogenology, 2008The replacement heifer represents the next generation of genetic progress for the cow herd. Producers invest a substantial amount of capital in these females, even if they fail to become pregnant. In order to get a return on this investment, it is imperative that these heifers become pregnant early in the first breeding season, calve with a minimum of ...
