Abstract

The research work was carried out to evaluate the effects of age and breed on semen quality of beef bull sires. The experimental site was located at Singosari National Artificial Insemination Center, Malang, Indonesia. A total of 180 ejaculate semen which were collected from 9 beef bull sires (3...

Abstract

In the current era of genomic selection, there is an increased demand to collect semen from genomically selected sires at a young age. The objective of this study was to assess the effect of bull age, ejaculate number, and season of collection on semen production (ejaculate volume, sperm...

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...

Abstract

The embryo production results after use of sex-sorted sperm to inseminate superovulated cows (SOV) have not been very encouraging so far, due to the low quantity of sperms used as well as their short half-life. In a previous study conducted in Brazil in Holstein cows, it was shown that using the...

Abstract

This study aimed to assess characteristics of bovine cryopreserved sperm and evaluate its relation to field fertility in fixed-time artificial insemination (FTAI). Semen samples of 16 bulls were used to inseminate 811 Nellore cows, and four of these bulls were also used to inseminate 101 Nellore...

Abstract

This study evaluated the effects of rainy and dry seasons on semen quality of bulls at Ungaran artificial insemination center. The semen was collected twice a week from one Ongole crossbred and one Simmental bulls, both at 5 years old, totaling 198 semen collections (99 of each bull). The results...

Abstract

Fertility is one of the most economically important traits in both beef and dairy cattle production; however, only female fertility is typically subjected to selection. Male and female fertility have only a small positive genetic correlation which is likely due to the existence of a relatively...

Abstract

Mammalian sperm are exposed to a natural hypoosmotic environment during male-to-female reproductive tract transition; although this activates sperm motility in vivo, excessive swelling can harm sperm structure and function. Aquaporins (AQPs) is a family of membrane-channel proteins implicated in...

Abstract

The use of artificial insemination in cattle breeding has evolved to global extent, and insemination doses are often shipped via air transport which requires strict radiation-based examinations. For the determination of effect of non-ionizing radiation (NIR), to which are beings frequently exposed...

Abstract

This study investigates the effects of iodixanol supplementation in varied concentrations to Tris egg yolk (TEY) extender on the quality and fertilization ability of frozen-thawed sperm of Thai native bulls. Each ejaculate was divided into four different groups, as follows: sperm were treated with...
