Thirty-three barrows, aged between 14 16 months with an average slaughter body approximately 140 160 kg, were randomly selected among 80 pigs reared two different systems, indoor or plein air. Carcase was recorded dressing percentage calculated. Longissimus thoracis (LT) muscles sampled grouped into: air low weight; high weight. Proximate composition, cholesterol, vitamin E fatty...

Over the years, efforts have been made to establish a reference protocol for first Italian rabbit semen bank. Here, we will provide an overview of our group’s key discoveries, which led us identify effective freezing semen. However, drawback involves diluting with media at fixed dilution ratios, resulting in significant variability sperm number per straw. Addressing this limitation underscores need standardise by investigating effect concentrations within straws on reproductive performances...
