Re: Forum: Achieving and Maintaining Fertility in Broiler Breeders

Hi,
It was very interesting to read your article where you mentioned all the key points related to semen and insemination. The success of
artificial insemination is directly dependent on the semen quality and its fertilizing capacity. For the decades, the sperm quality analysis like per cent motility, live-dead, morphological examinations of spermatozoa and dye reduction test were the commonly used techniques to assess the potential fertility of spermatozoa. However, there exists limitation in application of these sperm quality techniques due to the poor correlation between the test parameters and resultant fertility status of the laid eggs by inseminated birds. Methods employed for measuring fertility in samples of
egg from commercial turkey flocks are time consuming and are of limited quantitative value. A faster and more reliable quantitative analysis of flock breeding efficiency can be achieved by estimating the number of spermatozoa, which interact with the egg in the infundibulum.
Because, therea linear relationship between parameters of sperm quality and inner perivitelline layer (IPVL) holes.
So, we should tyake all the measures to have better sperm-egg interaction. This can be achieved if the breeders birds both males and females are good reserve of selenium in their body which will help to get more number of sperms penetrating the IVPL and hence better fertility and hatchability.
