Stimulating Reproductive Functions at Acyclic Cows by Ovsynch and Select Synch Protocols

open access: yesScientific Papers Animal Science and Biotechnologies, 2023
The purpose of our work was to compare the efficiency of two programs for the induction and synchronization of estrous and ovulation in acyclic cows (Ovsynch and Select Synch).

Estrous Synchronization in Lactating Cows

open access: yes, 1993
The objective of any successful synchronization program is to manipulate the estrous cycle of normally cycling females so that a large percentage will exhibit estrus with normal fertility at a pre-determined time.

A Subovulatory Dose of Human Chorionic Gonadotropin (hCG) May Sustain Terminal Follicle Development and Reproductive Efficiency during Anestrus in Sheep

open access: yesAnimals
The study tested the hypothesis that a single administration of hCG supports the LH-dependent phase of terminal follicular development in synchronized sheep during anestrus, using eCG as a functional reference. Using a clinical approach, four experiments

The ovarian function and endocrine phenotypes of lactating dairy cows during the estrous cycle were associated with genomic-enhanced predictions of fertility potential.

open access: yesJournal of Dairy Science
The objectives of this prospective cohort study were to characterize associations among genomic merit for fertility with ovarian and endocrine function and the estrous behavior of dairy cows during an entire, non-hormonally manipulated estrous cycle ...

Estrous Synchronization Programs for Lactating Cows

open access: yes, 2002
Two estrous synchronization experiments were conducted on lactating cows to compare the Select Synch program with the one injection PGF- 10-day program and the CO-Synch mass AI program.

Letrozole: A Steroid-Free Estrous Synchronization Method

open access: yes, 2018
Most bovine estrous synchronization protocols utilize progesterone plus estrogen to control ovulation timing. A drug that inhibits estrogen production (Letrozole) may be an alternative, steroid-free synchronization method (not yet commercially available).
