Comparison of muscle amino acid and fatty acid composition of castrated and uncastrated male pigs at different slaughter ages
 
M. Bianchi, M. Petracci, C. Cavani
 
 

The purpose of this study was to investigate the effects of castration and slaughter age on amino acid and fatty acid compositions in Longissimus dorsi (LD) muscle of pigs, as well as growth rates and meat quality.

 

The total amino acid, essential amino acid and nonessential amino acid contents of barrows were significantly higher than the ones of boars. Additionally, the content of several saturated fatty acids and total mono-unsaturated fatty acids was significantly higher, and total polyunsaturated fatty acids was significantly lower in the LD muscle of barrows than in boars.

 

The results suggest that the amino acid and fatty acid compositions of LD muscle from male pigs, as well as growth rates and meat quality, were influenced by castration, and, to a lesser degree, by slaughter age.
