The present study investigated the existing relationship between computer assisted semen motility parameters and gametes motility duration, known to express semen quality and fertilizing capacity in fish. The objective was particularly to identify computer aided semen analysis (CASA) parameters that could be used as potential fertility predictors. Semen samples were collected from the beginning...
Among internal fertilizers, typically fewer than 1% sperm survive the journey through the oviduct. Several studies suggest that the sperm reaching the ovum-the 'fertilizing set'-comprise a non-random sub-population, but the characteristics of this group remain unclear. We tested whether oviductal selection in birds results in a morphologically distinct subset of sperm, by exploiting the fact th...
Understanding of biology of the avian male gamete is essential to improve the conservation of genetic resources and performances in farming. In this study, the semen proteome of the main domestic avian species (Gallus gallus) and evaluation of the molecular phenotype related to sperm quality were investigated using GeLC-MS/MS approach and label-free quantitative proteomic based on Spectral Coun...
Sperm with reduced motility has reduced fertilizing capacity. If low-motile Duroc sperm is mixed with high-motile sperm, the fertilizing capacity of that dose is equal to semen doses exclusively containing high-motile Duroc sperm. With doses that only contained low-motile sperm, the number of total born piglets per litter dropped by minimum 0.5. Duroc boars were selected on the basis of the per...
