Abstract

Artificial insemination (AI) with cooled stallion semen has increased markedly during the last decades in all countries, but fertility is often lower than when fresh semen or natural mating is used. The objective of this study was to examine field data (1634, cycles 523 Standardbred (SB) mares, 575 ...

Abstract

Our objective was to compare the AI submission rate and pregnancies per artificial insemination (P/AI) at first service of lactating Holstein cows submitted to a Double-Ovsynch protocol and timed artificial insemination (TAI) versus artificial insemination (AI) to a detected estrus after...

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

Artificial insemination has been a landmark procedure in improving animal agriculture over the past 150 years. The utility of artificial insemination has facilitated a rapid improvement in animal genetics across agricultural species, leading to improvements of growth, health and productivity in...

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 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

Background: Artificial insemination is a preferred breeding method for beef heifers as it advances the genetic background, produces a predictive and profitable calving season, and extends the heifer's reproductive life span. As reproductive efficiency in heifers is key for the success of beef...

Abstract

Artificial insemination (AI) is widely used in farm animals for efficient utilization of superior males. However, AI is not being used in camels due to various difficulties involved in the process. In an attempt to develop the technology in camels, the present study was carried out to assess the...

Abstract

In cattle artificial insemination plays not only a vital role in the successful establishment of pregnancy, which is a prerequisite for initiation of the subsequent lactation, but also in accelerating genetic improvement and facilitating the distribution of semen from genetically elite sires. The...
