Effects of Age and/or Weight at Slaughter on longissimus dorsi Muscle: Biochemical Traits and Sensory quality in Pigs

摘要

The effect of increasing either age alone through feed restriction, or both age and weight at slaughter, on the quality of the longissimus dorsi muscle (LM) was investigated. Starting at 83 days of age and 32 kg, 80 pigs were allotted within liter to four experimental groups. All pigs were free of RYRl mutated gene. Pigs were fed either ad libitum (A100, A130) Or restricted 30/100 (R100, R130) and slaughtered at either 100 kg (A100, R100) or 130 kg (A130, R130) body weight.
