Campylobacter is one of the most commonly reported bacterial causes of human foodborne infections in the United States. Recent evidence has demonstrated that Campylobacter is present in poultry semen and may contribute to the vertical transmission between the breeder hen and offspring. As Campylobacter is considered sensitive to oxygen and cold temperature, the objective of this study was to de...

objective: the aim of the present study was to evaluate three thawing rates on the post thaw motility, viability and chromatin structure of buffalo semen frozen in 0.5-ml straws. materials and methods: in this experimental study semen was collected with artificial vagina (42˚c) from four buffalo bulls.split pooled ejaculates (n=4) were extended at 37˚c with a bioxcell® extender. semen was coole...

Background: Semen cryopreservation is the most important section of artificial insemination programs; it allows preservation of semen fertility for a long time. Materials and Methods: The aim of the present study was to detect the effect of in vitro supplementation of 4-hydroxy Tempo on fresh and frozen spermatozoa quality of buffalo bulls. Five healthy buffalo bulls (5 ejaculates from each bul...

semen from six adult male black bengal goats (capra hircus) was collected to compare the fresh and frozen-thawed semen quality and investigate its relationship with the fertility. each collected samples was divided into two parts: one part of semen was used as fresh and another part was filled into 0.50 ml straws, sealed, cooled (5 ˚c) and equilibrated for freezing.in both cases, semen was dilu...

The current study was performed to test the of quality as well as the DNA integrity of preserved liquid and frozen buffalo spermatozoa due to addition of different concentrations of glutathione (0.50, 1.00, 2.00 and 3.00 mM). Liquid semen was preserved for 120 hour with or without addition of glutathione and examined for progressive motility, viability, plasma and acrosomal membranes integrity ...
