  Journal of Dairy & Veterinary Sciences - Juniper Publishers Abstract Evaluation of the concentrations of the sperm macromolecule called proAKAP4, has been successfully introduced as a pertinent sperm parameter to assess sperm quality and high concentrations of proAKAP4 was shown to be highly correlated with sperm motility and fertility in large mammals. The sandwich ELISA kits known as Pig 4MID® Kits allowed the artificial insemination stations to monitor sperm quality more accurately with threshold values qualifying each ejaculate and animal. Introducing new methods and procedures are always challenging and sperm frozen collections have been suggested to standardize sperm assessment in daily routine. We thus have designed an experimental study to assess proAKAP4 stability and integrity in neat frozen ejaculates. Following baseline measurements, fresh ejaculates were aliquoted and stored at -20 °C for stability experiments up to 6 months and following up to 10 freeze-thawing ...

  Journal of Dairy & Veterinary Sciences - Juniper Publishers Abstract The study was conducted from August 2017 to December 2017 at the Kumasi Abattoir Company Limited to investigate the causes of carcass condemnation in slaughtered pigs and their associated financial losses. Out of the 1221 pigs examined, 212(17.4%) were affected with pathological conditions. The five most frequent pathological conditions were: Lung congestion (7.9%), Ascariasis (2.7%), Cysticercosis (2.4%), Liver congestion (1.1%) and Liver abscess (0. 9%). Pathological conditions were more prevalent (57%) in female pigs than in males (43%). Cross bred pigs were more (81%) affected by pathological conditions than the local Ashanti black pig (19%). The overall carcass condemnation rate was 1.7% with Cysticercosis being the major cause. The average condemnation rate of visceral organs was 1.8 %. Annually, a total of One hundred thousand, six hundred and twenty-eight cedis, seventy-two Pesewas (GHc100, 628.72) w...

  Journal of Dairy & Veterinary Sciences - Juniper Publishers Abstract The temperature in a liquid nitrogen storage tank is critical to maintain the viability of bovine semen stored within the tank. The objective was to determine the relationship of the temperature gradient in the neck of a tank to the level of liquid nitrogen in the tank. Using an electronic thermometer, temperature was measured at three locations: a) 2 cm below the top of the neck, b) 7 cm below the top of the neck (and below the frost line), and c) 2 cm above the level of liquid nitrogen. Liquid nitrogen volume in the tank was incrementally decreased from 18 L to 6 L. The experiment was repeated twice, and temperatures at each location and nitrogen level were recorded four times. Data on the effect of liquid nitrogen level, location, and two-way interaction on the temperature gradient in the neck of the tank were analyzed using a general linear mixed model procedure. There was an effect of location and volum...
