Abstract

This experiment was designed to compare pregnancy rates in postpartum beef cows following split-time (STAI) or fixed-time (FTAI) artificial insemination. Estrus was synchronized for 671 cows at seven locations following administration of the 7-d CO-Synch + CIDR protocol (100 µg GnRH+CIDR insert...

Abstract

Donkey farming is expanding because of the rediscovery of nutritional properties of jennies' milk for human consumption. In livestock, timed artificial insemination (TAI) allows to manage big herds without estrus detection, but there are very few studies on estrus synchronization in jennies. The...

Abstract

Objective: In this study, the transcriptome profile of cow experiencing miscarriage during peri-implantation was investigated. Methods: Total transcriptomes were checked by RNA sequencing, and the analyzed by bioinformatics methods, the differentially expressed genes (DEGs) were analysed with...

Abstract

There has been no report of equine embryo transfer in Japan for the last 24 years. Our objective was to establish an effective protocol for embryo transfer in domestic horse. A Hokkaido native pony was bred by deep-horn artificial insemination with frozen semen from a Connemara pony. Embryo...

AbstractFull Text

The aim of the present investigation was to evaluate the effect of the exogenous contribution of progesterone (P4) during 35 d post insemination in primiparous ewes on the percentage of gestation and embryonic mortality. Forty ewes were synchronized with the CIDR device, for a period of 9 d. Two d...

Abstract

Semen deposition through the cervix into the uterus is a difficult technique in ewes and represents the main limiting factor for insemination in this species. The objective of this study was to evaluate the pregnancy rate achieved with a new transcervical insemination method in comparison with...

Abstract

The objective of this study was to determine if there are differences in luteal size (LS), progesterone (P4), and luteal blood flow (LBF) between pregnant and non-pregnant Bos indicus dairy cows during the first three weeks after insemination, and whether these parameters are related to each other. ...

Abstract

The aim was to compare temporarily together the changes occurred along the early pregnant and nonpregnant mares on the ovarian, adrenocortical, thyroid, and hematochemical profiles (total protein, glucose, albumin, complete blood count). Sixteen mares were randomly divided into two groups: the...

Abstract

Using a 5-d controlled internal drug-release (CIDR)-Cosynch resynchronization protocol, the objective of this study was to determine the effect of the initial GnRH injection on pregnancy per artificial insemination (P/AI) to the second artificial insemination in lactating Holstein dairy cows. On...

Abstract

Our objective was to compare the insemination dynamics and time to pregnancy for up to 100 d after the beginning of the artificial insemination period (AIP) for heifers managed with first artificial insemination (AI) service programs that relied primarily on insemination at detected estrus (AIE)...
