Knowing the pregnancy status of females allows producers to make more informed and precise management decisions which increase efficiency and profitability.
Once a heifer has reached puberty, reproductive cyclicity begins.
Estrous synchronization is a reproductive management tool in which the estrous cycle is manipulated so that breeding females enter into estrus simultaneously.
Standing estrus, also referred to as heat, is a brief period within a female’s reproductive (estrous) cycle during which she will allow herself to be mounted.
Performing breeding soundness evaluations on herd bulls is a sound investment for beef cow-calf operations. A bull breeding soundness evaluation (BSE) is a uniform method of assessing a bull’s likelihood of accomplishing pregnancy in an appropriate number of open, healthy, cycling cows or heifers in a defined breeding season.
Research indicates that successful visual estrus detection and subsequent pregnancyrates are directly related to the frequency and duration of each heat check. The objective of this report is to describe a new heat detection system and to demonstrate its potential effectiveness for use with artificial insemination (AI) and embryo transfer (ET) procedures.
