Avaliação das características físico-químicas em carcaças e carne de suíno macho imunocastrado

Abstract

The consumption of pork has great economic importance in several countries. But in Brazil, although the pork chain is highly competitive, the meat consumption is still low when compared to chicken or beef. An investigation was carried out to evaluate the carcass characteristics and meat quality of male pigs immunocastrates compared to females. The pigs had around 110 kg, being differentiated by males immunocast and females with three replicates of five animals each. Carcasses were evaluated for hot and cold carcass yield and fat thickness (bacon) at two points. Samples were extracted for analysis of color, pH, shear force and odor, where analyzes were performed in triplicate 24 hours after slaughter. The results of this research showed that for the pH, color and thickness of the bacon there was a significant difference (p≥0.05), for texture and weight loss there was no significant difference (p <0.05). Regarding the cooking test, both treatments did not present a nasty odor characteristic of male. In this experiment it can be verified that some characteristics comparing immunoassays and females are perceptible but nothing that directly affects the final quality of the meat to the consumer.
