Effect of dietary net energy content on voluntary feed intake and growing performances of immunologically castrated males

The study indicates that a reduction of dietary NE up to 10 % with higher fiber content ingredients does not affect energy efficiency and provides an advantage in terms of reduced lipid deposition. This is particularly important when pigs are fattened to higher weights, i.e. when longer delays between immunocastration and slaughter are practiced.

Testes weight is not reliable tool for discriminating immunocastrates from entire males

The study evaluates the possibility of rapid discriminaiton between the carcasses of entire males and immunocastrates on the slaughter line or the possibility to assess effectiveness of immunocastration, based on the size of testes, vesicular gland and bulbourethral gland. The results show better discrimination in the case of immunocastrates than entire males. For the most efficient discrimination, measurements on all three sexual glands should be considered.

Hydrolisable tannin fed to entire male pigs affects intestinal production, tissue deposition and hepatic clearance of skatole

Study demonstrated an effect of tannin supplementation on intestinal skatole production, tissue deposition and hepatic clearance of skatole (activities of specific CYP P450 enzymes) in entire male pigs.
