Sperm mobility is defined as sperm movement against resistance at body temperature. Although all mobile sperm are motile, not all motile sperm are mobile. Sperm mobility is a primary determinant of male fertility in the chicken. Previous work explained phenotypic variation at the level of the sperm cell and the mitochondrion. The present work was conducted to determine if phenotypic variation c...
For the trajectory optimization of time–jerk robotic arms with a chicken swarm algorithm, using five-order B-spline interpolation can ensure smooth and continuous acceleration, but, due to performance problems low solution accuracy slow convergence speed, ideal curve cannot be obtained. To address these problems, an improved algorithm based on parallel strategy dynamic constraints (PDCSO) is pr...
We show that mouse sperm die spontaneously within 1-2 days in culture and that treatment with either staurosporine (STS) and cycloheximide (CHX) or a peptide caspase inhibitor does not accelerate or delay the cell death. Chicken erythrocytes, by contrast, are induced to die by either serum deprivation or treatment with STS and CHX, and embryonic erythrocytes are more sensitive than adult erythr...
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...
Ex situ preservation is an important method in the of chickens, and cryopreservation semen only for gamete at present. During last two decades, many studies have been performed to develop standard chicken technology achieve great progress. Many attempts methods were investigated adapt subspecies or different breeds. In this paper, we firstly reviewed main factors affecting sperm, including uniq...
