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

Estrus synchronization and artificial insemination are commonly used as a pair of matching technologies in sheep breeding. In view of the uneven estrus synchronization rate and conception rate in practical production, the estrus synchronization method of "CIDR+PMSG+PG" is introduced and the...

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

The use of artificial insemination in cows makes possible breeding of superior animals, which are known as enhancer individuals. However, the major limitation for its expansion has been the necessity for estrus detection. Thus, programs of fixed time artificial insemination (FTAI), without the...

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

Brazil has a large flock of sheep, with about 18.41 million heads. Genetic improvement is a way to increase farm productivity, with fixed-time artificial insemination (TAI) being used for this purpose. Therefore, the objective of this study was to evaluate the interval between estrus manifestation...
