Abstract

This study aimed to compare the reproductive efficiency of dairy buffaloes subjected to TAI protocols based on progesterone, estrogen, and equine chorionic gonadotrophin (P4/E2+eCG) during the fall/winter (n=168) and spring/summer (n=183). Buffaloes received an intravaginal P4 device (1.0 g) plus...

Abstract

The objective was to compare the fertility of dairy cows using a presynchronization protocol by induction of a largest follicle using a progesterone intravaginal device prior to an Ovsynch protocol (P4synch) with the Double-Ovsynch in lactating dairy cows. Lactating Bos indicus × Bos taurus...

Abstract

Egg yolk is used as a cryoprotectant in semen preservation. However, its composition varies according to the species which may influence its effectiveness during the freeze-thaw process. Therefore, study was conducted to identify the optimum level of pigeon egg yolk (PEY) in Tris citric acid (TCA)...

Abstract

The Amur leopard cat (Prionailurus bengalensis euptilurus) is a globally endangered species, and there is thus an urgent need to increase its population. The objectives of this study were to: (1) confirm the utility of urethral catheterization (UC) for semen collection from Amur leopard cats; (2)...

Abstract

The aim of the present study was to evaluate the effect of serum progesterone concentrations during the superstimulatory treatment of the first follicular wave on fertilization rate and embryo development in sheep. A total of 71 Merino ewes received a superstimulatory FSH treatment during Wave 1 of ...

Abstract

Two experiments were conducted to investigate the role of relatively lesser and greater progesterone (P4) concentrations during early follicular development on ovulatory follicle growth and pregnancy rate in beef cattle. In Experiment 1, time of ovulation was synchronized with the 5 d CO-Synch +...

Abstract

The ewe's cervix structure is highly variable among females, which may limit the application of transcervical artificial insemination (TCAI). This work aimed to study the variation in cervix anatomy in two different prolificacy breeds (D'man a prolific and Boujaâd a non-prolific sheep)....
