Deterioration of Frozen Semen of Bali Cattle after Cooling at 5°C
نویسندگان
چکیده
Frozen semen is produced through several stages, which deteriorate spermatozoa. This research aimed to evaluate the deterioration degree of frozen after 5 °C cooling and freezing Bali cattle. The samples included 10 male cattle with a body weight 542-668 kg, from was collected once week for five weeks. each individual’s sperm determined by observing two distinct straws. parameters observed viability, abnormalities, intact plasma membrane, acrosome cap. Initial observations were conducted following addition diluent A1 (AD) as much volume fresh semen. in AD group not cooled frozen. then divided into two, namely, those at 4 hours (PT1) 5°C 22 (PT2). results showed that individual variations caused significant differences viability membrane PT1 groups, while PT2 did differ Abnormalities significantly different between however abnormalities Intact acrosomal cap AD, PT1, groups. In conclusion, variations, including spermatozoa, better compared hours. A Cooling time can be recommended processing.

Effect of cooling on sperm motility before and after frozen-thawed stallion semen
The aim of this study was to assess the effect of cooling on sperm motility before and after frozenthawed stallion semen. Fifteen ejaculates of three stallions were collected with artificial vagina. The progressive motility was determined under microscope immediately after collection, cooling (5°C for 0, 2, 7 or 24 h) before frozen-thawed and cooling (5°C for 0, 2, 7 or 24 h) after the semen wa...
متن کاملMicrobiological deterioration of frozen parfried potatoes upon holding after thawing.
Frozen parfried potatoes were thawed and stored at 55, 45, and 34 F (12.8, 7.2, 1.1 C). Significant changes in flavor and texture did not occur at these temperatures until the total bacterial count exceeded 100 million per gram. These sensory changes were produced after 4, 8, and 20 days of storage at 55, 45, and 34 F, respectively. Detectable color change appeared sooner and probably was not o...

Infectious pustular balanoposthitis (IPB) is one of the reproductive disorders caused by bovine herpesvirus 1 (BoHV1) that can be transmitted through artificial insemination. A herd of 63 breeding bulls at a frozen semen bank in Odisha state in India experienced a suspected outbreak of IPB, with 11 bulls showing clinical signs of the infection. Clinical signs were noticed in two bulls initially...
