Abstract

Four controlled experiments designed to examine aspects of reproductive response in Broad-Breasted males were conducted. 24 males and 168 females were used to evaluate the use of low sperm concentration (30.6 X 106 spermatozoa/AI dose) and examine the relationship of semen characters to fertilising ...

Abstract

Biweekly determinations were made of semen volume, semen concentration and sperm motility for each of 47 individually caged Peel's Cornish male fowls from 39 to 63 wk of age. Young birds of 3 strains (1 White Rock and 2 dwarf) and force-moulted birds of 3 strains (2 White Rock and 1 dwarf) were...

Abstract

The genetic breeding improvement plan carried out in the past decade, put emphasis on the selection characteristics such as weight gain, rapid growth in broiler breeders as cause of reduced fertility rate. This occurred due to the negative correlation between reproductive and productive trials....

Abstract

Semen was collected from 10 roosters, after which they were divided into 2 groups of 5 birds each. In Group I, semen was collected after 24 h, followed by second and third collections after 48 h and 72 h until ejaculate volume decreased significantly. Semen collection was then conducted once every...

Abstract

This review focuses on natural and assisted prevention against lipid peroxidation in avian spermatozoa. The presence of high levels of n-6 polyunsaturated fatty acids (PUFAs) in the plasma membrane creates favorable conditions for the formation of peroxidative products, a major cause of membrane...

Abstract

Birds, reptiles and insects (e.g. Hymenoptera) share fundamental similarities in their reproductive strategies due to the presence, in the female tract, of specialized sites in which spermatozoa may reside for prolonged periods upon a single mating. In avian species, two distinct storage sites are...
