Effect of immunocast ration in combination with addition of fat to diet on quantitative oxidation of nutrients and fat retention in male pigs

摘要

Immunocastration (IC) has been studied as one of the possible replacements for surgical castration of male pigs to block reproductive function and eliminate boar taint. It has a positive effect on performance (Batoreketal, 2012) but after IC, increased feed intake (FI) and fat deposition indicate changes at the metabolic level. The objective of the study was to determine the effects of IC and increase of dietary fat on energy (E) metabolism and relationships between digested nutrients and their final outputs for catabolic and metabolic process in fattening pigs.
