Effects of dietary protease supplementation on behaviour, slaughter performance, meat quality and immune organ indices of broilers

This study was conducted to investigate the effects of protease supplementation on behaviour, slaughter performance, meat quality, and immune organ indices broilers. A total 240 one-day-old Arbor Acres broiler chickens were randomly allocated four treatments, with six replicates per treatment 10 broilers replicate. Chickens fed corn-soybean meal basal diets supplemented 0, 4, 8, 12 IU/g protease. Compared 0 supplementation, increased average minimum time feeding drinking behaviour (P < 0.05); average, maximum, preening decreased feeding, walking, stretching frequency 0.05). pH24h breast thigh muscles had improved The shear force the muscle cooking loss protease, 4 lying 0.05) stretching, scratching, aggressive < spleen index enhanced Protease can be used as an additive in a diet for production.
