Abstract

The aim of this clinical trial was to quantify the results of pregnancy after treating trypanotolerant N'Dama female cattle (n=168) with a progesterone-releasing intravaginal device (CIDR; 1.38 g of progesterone) inserted for seven days. An intramuscular (IM) prostaglandin injection (500 µg of...

Abstract

Introduction D-cloprostenol is a synthetic PGF, commonly used in bovine reproduction, that increases myometral contractility. However, little is known regarding its contractile behaviour and how it depends on the reproductive state and uterine topography (regions and muscular layers). Hypothesis...

This study proved that previously manipulated hormonal mares with different schemes for synchronization of oestrus cycle - using prostaglandins and combined use of progestins and prostaglandins, fecundity remains at insemination with cryopreserved semen. Furthermore it was found preserving...

AbstractFull Text

The present study was carried out to evaluate the efficacy of certain hormonal treatment protocols for augmenting the conception rate. Following artificial insemination during spontaneous estrus of repeat breeding cows yielded a conception rate of only 33.33% and this could not be improved if they...

Abstract

The objectives were to evaluate the pattern of re-insemination, pregnancy outcomes to re-insemination in estrus and at fixed time, and economic outcomes of lactating Holstein cows submitted to three resynchronization protocols. Cows were enrolled in the Experiment at 32±3 d after pre-enrollment ...

Abstract

Pregnancy per artificial insemination (P/AI) following Ovsynch is optimized when cows ovulate to the first GnRH of Ovsynch. Fertility programs are designed to presynchronize cows to d 6 or 7 of the estrous cycle to increase the chances of ovulation of a first-wave dominant follicle to the first...

Abstract

A total of sixteen Holstein dairy cows (35±1.1 kg/d of milk yield) were randomly assigned to consider the effects of feeding omega-3 sources on endometrial endocannabinoids system (ECS) genes expression to understand the effect mechanism of omega-3 on reproductive performances during the early...

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

Our hypothesis was that increasing the length of an estradiol and progesterone (P4) timed artificial insemination (TAI) protocol would improve pregnancy per artificial insemination (P/AI). Lactating Holstein cows (n=759) yielding 31±0.30 kg of milk/d with a detectable corpus luteum (CL) at d -11...
