INFLUENCE OF ESTRUS PRE-SYNCHRONIZATION ON REPRODUCTIVE VARIABLES IN KATAHDIN EWES CARRIERS OF THE GDF9 GENE

open access: yesTropical and Subtropical Agroecosystems, 2023
Background: Genetic improvement in the sheep species focuses on increasing the number of offspring per sheep. Heritable characteristics such as ovulation rate, fertility, and prolificacy are desirable.

APPLICATION OF ESTRUS SYNCHRONIZATION USING PGF2α AND OVULATION SYNCHRONIZATION USING hCG FOR ARTIFICIAL INSEMINATION OPTIMIZATION ON ONGOLE (PO) BREED CATTLE [PDF]

open access: yesJurnal Kedokteran Hewan, 2018
This study aimed to determine the pregnancy percentage of Ongole (PO) breed cattle by estrus synchronization and ovulation synchronization. This study used 22 cattle that were divided into three groups: Estrus synchronized cattle (K1, n= 5); ovulation ...

Status of On-Farm Artificial Insemination Services and Effectiveness of Oestrus Synchronization in Dairy Cattle Under Small-Scale Dairy Farming System. [PDF]

open access: yesVet Med Sci
Cross‐sectional survey and retrospective data on the oestrus synchronization were collected and analysed. The predominant mating system practiced by dairy farmers was AI (55.6%), and 73.5% of farmers apply controlled mating. The highest response rate and pregnancy rate were 89.5% and 45.2%, respectively, whereas a birth rate of 9.6%–18.5% was obtained.

The CIDR-GPG Protocol Improves Reproductive Efficiency in Yaks and Lowers the Body Condition Requirements for Success [PDF]

open access: yesAnimals
Yaks are a critical livestock species for plateau regions; however, their poor reproductive efficiency—characterized by low estrus and pregnancy rates—significantly hampers genetic improvement and industry sustainability.

Estrus synchronization in cattle

open access: yes, 2014
The purpose of estrus synchronization is to manipulate the bovine estrus cycle and achieve a result were the majority of animals on a farm exhibits standing heat in a short period of time. It is a very effective method to increase the proportion of animals that are bred at the beginning of the breeding season.
