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

The objective of the present study was to evaluate the effects of clinical mastitis at the beginning of lactation on reproductive performance of dairy cows in Algeria. Calving to first insemination and calving to conception intervals, number of insemination per conception and conception rate at the ...

Abstract

Artificial insemination is beginning to find its place in Algerian dairy cattle farms. The bovine artificial insemination (AI) assessments for a three-year period in the semi-arid wilaya of Sétif on 4 855 insemination acts carried out by 5 inseminators in 3 664 cows of 5 different breeds belonging...

Abstract

To assess the effect of the angiotensin-converting enzyme (ACE) inhibition on the efficiency of the fixed-time artificial insemination (TAI), 69 goats were divided randomly into two groups: enalapril (n=35) and control (n=34). In the experiment, all animals underwent the protocol of fixed-time ...

Abstract

The quality of extenders and the synchronization of heat are key factors in the success of artificial insemination in rabbit breeding. The aim of the study is to set up local extender for artificial insemination and evaluate the effect of heat synchronization on the success of artificial ...

Abstract

The aim of this study was to quantify the effects of progesterone profile features and other cow-level factors on insemination success to provide a real-time predictor equation of probability of insemination success. Progesterone profiles from 26 dairy herds were analyzed and the effects of profile ...

Abstract

The principle of ovsynch-timed artificial insemination and the methods and reproductive application of estrus synchronization and ovsynch-timed artificial insemination in dairy cattle were summarized. Accurate and timely estrus detection of dairy cattle in their estrus cycle was the foundation for ...

Abstract

This study compared the effects of natural mating and artificial insemination using frozen buck semen on reproductive performance in Alpine goats. Sixty reproductive Alpine goats were grouped according to natural mating (n=30) and artificial insemination (n=30) breeding methods. Oestrus was...

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...
