Feeding Iberian × Duroc cross pigs with crude glycerine: Effects of diet and gender on carcass and meat quality

Meat Science
M EgeaF Hernández

Abstract

Ninety (45 castrated males and 45 gilts) Iberian × Duroc pigs were used in this study. During the finishing period (95-160 kg body weight, 74 days) animals received conventional feed (control G0) or the same feed plus 5% (G5) or 10% (G10) of crude glycerine to partially replace wheat. In general, neither the diet nor gender affected ultrasound, carcass or meat quality parameters. The G10 had lower values of cooking loss and a* than the G5 and G0 groups. The fatty acids, C10:0, C12:0 and C18:3, in intramuscular fat were lower in both glycerine groups. Polyunsaturated fatty acids and 18:2 decreased and C20:0 increased at the subcutaneous fat of G10 animals. Castrated males produced carcasses with higher backfat thickness and fat content. Castrated males had a higher SFA content in subcutaneous fat than females (P<0.001). In conclusion, up to 10% crude glycerine could be used in the Iberian × Duroc diet.
