24 h storage

Free amino acids are found in spermatozoa and seminal plasma. Their qualitative and quantitative presence have been affected by many factors. Under in vitro storage conditions, their effects on spermatozoa in animal species and also human have been concerned over the last decades. In this study, the effects of tryptophan, phenylalanine and cysteine on DNA integrity, lipid peroxidation, viability and motility parameters in spermatozoa of the common carp (Cyprinuscarpio) were assessed during short-term storage.

The present study was conducted to compare the quality of vacuum packed superchilled (- 1.5 to -2.5ºC) chicken breast with the chilled and frozen chicken breast at 24 h of storage. The result showed improvement in moisture content of superchilled meat with reduction in protein content as compared to fresh meat. There were no significant difference (P>0.05) in fat content of treated samples. The pH and WHC % showed no significant effect of cooling treatments. The ERV was good in treated samples except in chilled samples wherein it was decreased significantly.

The aim of this study was to evaluate the effect of Tris-based extenders containing glycerol and egg yolk on the motility and viability of chilled ram semen collected during non-breeding season. Nine ejaculates from three healthy rams in non-breeding season were collected by artificial vagina method. The semen was diluted with Steridyl (ST), Triladyl (TRY) or Tris-based extender containing 5 % glycerol and 5% egg-yolk (TGGY) to a final concentration 200x109 spermper ml. Semen samples (n=9) for each extender were stored at 5 0C for 72 hours.
