Abstract

Reducing the number of sperm needed to produce a litter with artificial insemination (AI) allows greater use of higher genetic merit boars. Induced ovulation with single fixed-time artificial insemination (SFTAI), combined with intrauterine (IUI) or deep uterine insemination (DUI), could improve...

Abstract

The breeding of giant pandas Ailuropoda melanoleuca in captivity can be a challenge, especially if natural mating is unsuccessful and artificial insemination is the only way to achieve fertilisation. The best chance of successful artificial insemination is when the female is inseminated within 24...

Abstract

Until recently, labor required to detect estrus for individual cows or heifers in a herd was the primary reason beef producers viewed artificial insemination as impractical. However, improvements in methods to control estrus and ovulation in beef heifers and cows are now expanding the use of ...

Abstract

The beef industry is increasingly taking advantage of effective methods available to synchronize ovulation in beef females. In addition to wide genetic choices possible with artificial insemination, estrus synchronization consolidates calving, increases calf age at weaning and with each season,...

Abstract

Successful cryopreservation of bison semen is fundamental for restoration of genetic diversity in Canada's wood bison. Conventional bovine semen extenders contain animal products, such as egg yolk and milk, which are undesirable because of biosecurity risks and undefined composition. In this study, ...

Abstract

This study was conducted to determine effects of pre-synchronization of ovulation timing among heifers and delayed fixed-time artificial insemination (TAI) with sex-sorted semen on proportion of heifers pregnant after TAI (PR/AI). Heifers were assigned to one of eight treatments: (1 and 2), 7-d...

Abstract

Artificial insemination protocols depend on efficient behavioral estrus detection and insemination time in Angora goat. Therefore, we aim to determine the accuracy of an estrus scoring system in Angora goats with different PMSG doses during the breeding season. Does (n: 260) were randomly divided...

Abstract

The effects of standard uterine body and hysteroscopic insemination on endometrial health were investigated. For this purpose, 33 mares were assigned to five different protocols: control (no insemination; n = 7), sham AI (sham uterine body insemination; n = 6), sham HysAI (sham hysteroscopic ...

Abstract

This study was conducted to evaluate various factors affecting fertility following insemination of dromedary camels. In experiment 1, camels were either bred by natural mating (NM) or inseminated in the body of uterus with whole, split (50:50) or 1 mL of undiluted ejaculate. In experiment 2, camels ...

Abstract

Objective: There exist differences in the reproductive behavior of stallions and mares under free-running and domestic in-hand breeding conditions. Contrary to artificial insemination programs, a stallion mates a mare multiple times per estrus under natural conditions. The objective of this study...
