Synchronization of Estrus in Dairy Heifers: A Field Demonstration

open access: yesJournal of Dairy Science, 1986
Use of prostaglandin F2 alpha to synchronize estrus was demonstrated over 3 yr with 2966 dairy heifers in 45 herds. Reproductive status of all heifers was determined before any injections occurred. Anovulatory heifers (8.3%) were not injected or inseminated. Ovulatory heifers received one intramuscular injection and most heifers received two injections

Estrus Synchronization in Pigs

open access: yes
Estrus synchronization is a technique that involves managing the reproductive cycles of sows to bring them into estrus (heat) at the same time and making it easier to the fixed time insemination and increase the efficiency of breeding programmes. This practice is especially beneficial in the tropical regions where the environmental stress factors such ...
