Analysis of poultry fertility data. Vitamin E requirements for female birds: Also, a bundle of sperm extruding into the lumen of the UVJ from the SSTs was frequently seen at 20 h after oviposition, while no such sperm were observed at 8, 14 or 25 h. The SST cells grew as tightly knit monolayers on top of the feeder cells at a slow rate approximately 96 h doubling time at a medium pH of approximately 6. Ovary of a chicken in egg production.
Because of the presence of a system that maintains the ejaculated sperm alive in the female reproductive tract in a variety of animals, this strategy appears to be. tion, sperm viability, and subjective motility assessment, . store sperm in the hen for extended periods of time. This “reservoir” of sperm within .. female fertility.
To release themselves from the oviductal storage reservoir, sperm undergo motility hyperactivation; however, the process is not understood.
Proteomic analysis by mass spectroscopy of the conditioned medium of the cells, and of the cells themselves, showed the cell lines did not secrete large amounts of any particular protein, and the analysis confirmed their epithelial character. In addition, it is reported that the sperm stored in the. In vertebrates, sex organs are generally specialized to perform a male or female reproductive role. Evidence for the innervation of sperm storage. Bakst MR, Akuffo V.
Giraldelli; Sperm-egg interaction and fertility of Japanese breeder quails from 10 to 61 weeks, Poultry ScienceVolume 92, Issue 1, 1 JanuaryPages —, https: The influence of the age of Japanese breeder quails was studied by the analysis Time viable sperm in female poultry fertility and sperm-egg interactions on the perivitelline layer of fertile eggs along the reproductive lifetime. Thus, 10 quail couples were observed every 30 d from 70 to d. In each analyzed period, the males remained with the females for 24 h, and the oviposited eggs were analyzed up to the laying of 3 consecutive infertile eggs. The number of sperm trapped in the perivitelline layer overlaying the germinal disc was reduced as a function of the age of the females and the time after copulation. For breeder Japanese quails, the age of the females represents an important factor for fertility maintenance.
