Mensuration of spermatozoa from different levels of the reproductive tract of the buffalo - bull ( Bubalus bubalis )
نویسنده
چکیده
The dimensions of spermatozoa from different levels of the reproductive tract were measured in 6 buffalo-bulls castrated under local anesthesia ; the same measurements were taken in the semen of 6 breeding buffalo-bulls. During transit from caput to cauda epididymis the sperm showed a significant increase in the length of head and main piece. However, a significant decrease was observed in middle piece length. In ejaculated sperm there was a significant decrease in total length and in head and main piece length.

P-70: Effect of Xylose on Epididymal Sperm Motility in Water Buffalo (Bubalus bubalis)
Background: In mammalian spermatozoa, motility is one of the most important parameters for evaluating the quality of the semen. From a functional point of view, motility is strongly related to the spermatozoa’s ability to manage its energy status, Thus, modulation of energy status could be translated into significant changes in motility patterns. The aim of the present study was to evaluate xyl...

The aim of the present study was to investigate the effect of in vitro supplementation of selenium on fresh and frozen spermatozoa quality of buffalo (Bubalus bubalis) bulls. Five healthy buffalo bulls (5 ejaculates from each bull) were used. Each ejaculate was diluted at 37 ˚C with tris-based extender containing 0 (control), 0.5, 1, 2, 4 and 8 μg mL-1 sodium selenite and the sperm motility and...
