AbstractFull Text

The objective of the present work was to evaluate the effect of treatment of estrus cycle control (Co-Synch 5 days; J-Synch or Device by 7 days), reproductive status (cyclic or anestrus) and equine chorionic gonadotropin (eCG) on pregnancy rate after fixed time artificial insemination (FTAI). Angus ...

Abstract

The objective was to determine associations between behavior during head-lock restraint and reproductive performance in dairy heifers. Behavior of 817 Holstein heifers from four farms was evaluated at feeding (Days 0 and 7) while restrained in a self-locking stanchion. All heifers were assigned a...

Abstract

The usefulness of a radiotelemetric pedometer for estrus detection in standing (ST) heat, or in silent heat without ST events, but in which ovulation is observed, in Japanese Black cattle was investigated. The duration of an increase in steps in ST heat was 11.8±1.3 hr, and it was similar to that...
