Abstract

Artificial insemination of cattle became a commercial reality in 1936, and in 1952 the first calves were born as a result of freeze-thawed semen insemination. The long-held aspiration for pre determination of sex became a reality with the development of sperm sorting technology with the first...

Abstract

Little is known of the genetic variability in semen quality traits in cattle and their inter-relationships. The objective of the present study was to estimate genetic parameters for a range of semen quality measures. The data consisted of 35,573 ejaculates from 787 artificial insemination bulls of...

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

The technology available to assess sperm population characteristics has advanced greatly in recent years. Large artificial insemination (AI) organizations that sell bovine semen utilize many of these technologies not only for novel research purposes, but also to make decisions regarding whether to...

Abstract

There is a growing need for sexed semen of cattle in India. Farmers prefer female calves of cows or buffalos than male calves as they can produce milk in the future which is economically more beneficial. Very few bulls are required for breeding in herds and they are no more required in agricultural ...

Abstract

The aim of this study was to identify the effects of adding quercetin (Q) to Tris extender in order to identify levels of oxidative stress in bull sperm after freeze thawing. Ejaculates were collected via artificial vagina from Holstein bulls. Semen was divided into five tools and diluted to a...

Abstract

Commercial doses of frozen bull semen for artificial insemination may have a certain percentage of morphological defects, despite being subject to prior selection. The aims of this study were to determine the prevalence of morphological abnormalities in commercial doses (n=55, r=2) of dairy and...

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

Five hundred and ninety five frozen semen samples of crossbred Jersey bulls were subjected to frozen semen evaluation tests such as postthaw motility, post-thaw incubation survival, hypo-osmotic swelling and acrosome integrity to study the effects of non-genetic factors namely farms, ejaculate...
