Abstract

In sheep industry, genetic progress rate achieved by artificial insemination (AI) is limited by the convoluted anatomy of the cervix, which does not allow the passage of an insemination catheter for uterine semen deposition. The aim of this study was to test, in 98 pregnant at term Sarda ewes, the...

Abstract

On commercial farms, rabbit does are subjected to a reproductive rhythm that does not account for their welfare or physiology, leading to reduced longevity and consequently high annual replacement. The European Food Safety Authority (EFSA) recommends limited and infrequent use of hormone...

Abstract

Current bovine pregnancy detection methods are not reliable until at least day 28 post artificial insemination (AI). The bovine estrous cycle is approximately 21 days; consequently, producers miss an opportunity to rebreed at the next estrous event. Therefore, commercial interest exists for the...

Abstract

Numerous treatments and protocols have been used to control the reproductive cycle in cattle, with varying effectiveness and many involving the administration of steroid hormones. Steroid hormones, such as estradiol, are perceived as having a negative impact on consumer health. This internationally ...

Abstract

Background: The aim of the study is to evaluate the effectiveness of thermographic monitoring, using the temperature changes of perianal and perivulvar areas for the determination of estrus in Anatolian Shepherd bitches. Fifteen bitches were used in the study. Blood and vaginal smear samples were...

AbstractFull Text

The goal of this study is to estimate the effects of low-level laser irradiation (LLLI) on the superovulatory response according to the number of corpora lutea (CL), follicles (F) and the embryo yield. In recent years, while searching for new, more efficient and organic methods to improve...

Abstract

Two long-term, CIDR-based estrus synchronization protocols were evaluated among Bos indicus-influenced and Bos taurus beef heifers. Treatments were evaluated on the basis of estrous response and pregnancy rate resulting from fixed-time artificial insemination (FTAI), and these outcomes were...

Abstract

Endoscopy enables a rapid and non-traumatic examination of the vaginal cavity of female dogs. Its implementation requires specific equipment as well as knowledge about the species-specific vaginal anatomy and the procedure. Vaginoscopy is the diagnostic tool of choice for several vaginal conditions ...

Abstract

Intrauterine plant oil infusion, including fractionated coconut oil, has been previously found to be a safe, inexpensive, and reversible method of prolonging the luteal phase in mares when administered on Day 10 of the estrous cycle. Our objective was to understand the uteroovarian response to the...
