Some effects of nutrition and castration on meat production from male Suffolk cross (Border Leicester-Romney cross) lambs

摘要: Abstract Meat quality of Suffolk cross (Border Leicester-Romney cross) lamb carcasses was assefsecl by taste panels and objective measures shear force sarcomere length. In one experiment the meat from lambs raised on pasture at least as good that receiving either barley-based pellets or a diet containing high levels protected polyunsaturated fatty acids (PPF A) for an ex:ended period (mean 112 days). The PPFA-fed group produced significantly tougher less juicy than did pasture-fed lambs; its acceptable characteristic flavour. Some sets measurements indicated barley feeding slightly decreased tenderness, flavour, juiciness relative to feeding. Carcass fat contained average 22.9% linoleic acid; non-carcass depots had higher levels. ratio oleic: stearic acid in fed those pasture. A second showed little difference between quali...
