Abstract

The aim of the experiment was to evaluate the reproductive performance of ewes synchronized with two doses of prostaglandin F (PG) at different intervals and inseminated at a fixed time. During the breeding season (April to June), 370 multiparous Corriedale ewes were assigned to five groups...

Abstract

The aim of this study was to evaluate the reproductive impact of a short-term protein supplementation on a long interval prostaglandin-based protocol (two PG injections 15 d apart; PG15) for timed artificial insemination in sheep. During the breeding season, 437 multiparous Merino ewes grazing...

Abstract

Fixed-time artificial insemination (FTAI) is the most effective method to increase the number of females inseminated in a single day, eliminating the necessity of estrus detection. Usually the treatments for FTAI in sheep are based on the use of progesterone-releasing devices and equine chorionic...

Abstract

This study aimed to determine whether reproductive performance of ewes submitted to laparoscopic timed artificial insemination (TAI) would be similar to ante meridiem (AM)/post meridiem (PM) rule and assisted natural mating (NM), and whether GnRH may enhance the pregnancy rate in TAI. In experiment ...

Abstract

The objective of the present study was to determine the ovarian response induced with the prostaglandin-based protocol Synchrovine (two doses of PGF given 7 d apart), as well as the fertility after FTAI. In Experiment 1, 15 females received the Synchrovine protocol using two different PGF...

Abstract

The objective of this study was to evaluate the ovarian response to equine chorionic gonadotropin (eCG) administrated during the luteal phase after insemination in sheep. Thirty cyclic multiparous ewes received a fixed-time intrauterine insemination (Day 0) and were assigned to three experimental...

Abstract

It was recently demonstrated that equine chorionic gonadotropin (eCG) treatment 10 days after ovulation increases serum progesterone concentrations in sheep. The objective of the present study was to evaluate pregnancy outcomes induced with the administration of eCG and gonadotropin-releasing...

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

Female reproductive technologies such as multiple ovulation and embryo transfer (MOET) and juvenile in vitro fertilization and embryo transfer (JIVET) have been shown to accelerate genetic gain by increasing selection intensity and decreasing generation interval. Genomic selection (GS) increases...

Abstract

Benefits of genomic selection (GS) in livestock breeding operations are well known particularly where traits are sex-limited, hard to measure, have a low heritability and/or measured later in life. Sheep and beef breeders have a higher cost:benefit ratio for GS compared to dairy. Therefore,...
