Abstract

Semen quality assessment requires accurate, reliable and objective methods for examination of sperm variables including sperm motility. For preparation of semen samples for artificial insemination, as a genetic resource, samples that are used for insemination need to have the capacity to result in...

Abstract

To increase the efficiency of equine semen, it could be useful to split the artificial insemination dose and refreeze the redundant spermatozoa. In experiment I, semen of 10 sires of the Hanoverian breed, with poor and good semen freezability, was collected by artificial vagina, centrifuged,...

Abstract

The number of doses per pregnancy gives an indication of the fertility of the cow, the quality of semen and insemination. Therefore, the goal of this study was to investigate the relationship between the physical and morphological assessment of semen cryopreserved in Central with the number of...

Abstract

This study was conducted to investigate the effect of D-Aspartic acid (D-Asp) on post-thawed sperm quality, fertility and hatchability outcomes in male broiler breeders. Twenty 55-week-old roosters were selected and equally split into four groups (n=5 rooster/group). Different daily D-Asp doses...

Abstract

Many attempts have been made to identify laboratory tests that are predictive of sperm fertility, both to improve the quality of stallion semen doses for artificial insemination (AI) and to identify potential breeding sires if no fertility data are available. Sperm quality at the stud is mostly...

Abstract

The turkey industry relies totally on artificial insemination to continue and improve production. If something compromises the insemination process, such as contaminated semen, it becomes a detrimental loss to the industry. Bacteria have been found in broiler breeder males to reduce sperm motility. ...

Abstract

Artificial insemination with cooled semen is routine in equids because of its good fertility rates and relatively low costs. In several donkey breeds, especially in restricted populations, the use of cooled semen could be seen as the best way of improving reproductive performance and avoiding...

Abstract

Frozen-thawed boar sperm (FTS) has reduced motility and viability compared to cooled semen. Motility of FTS is related to in vitro and in vivo fertility, but this effect has not been determined in relation to the timing of ovulation. To test the effect of variable FTS motility in a multiple-AI...

Abstract

The good results obtained in the improvement of livestock in the U.S.S.R. by selection and inbreeding are briefly discussed. The possible danger of such a policy is pointed out and illustrated by the case of the Mazoev breed of sheep, which was noted for length of wool. Over concentration on this...
