Quality of meat from sheep fed diets containing spineless cactus (Nopalea cochenillifera Salm Dyck)

It was aimed to evaluate the effects of replacement of wheat bran in lambs' diets with spineless cactus (0, 33, 66, and 100%) in a lamb's diet on the physicochemical parameters, fatty acids and sensory analyasis of meat. The evaluation utilized 36 loins and legs from F1 1/2 Dorper x 1/2 Santa Ines lambs, with an average initial body weight of 19.5 +/- 1.6 kg, were slaughtered after 70 days of confinement. Were found average values of 5.70, 11.27 N, 55.44 mg/100 g, of meat pH, shear force, and cholesterol, respectively. However, stearic acid, linoleic, linolenic, eicosatrienoic and eicosapentaenoic which linearly decreased. The color, aroma, texture, flavor, juiciness and global acceptance of meat were acceptable by the evaluators, additionally, they said they would buy meat coming of animals fed with 100% replacement. It is recommended that wheat bran is replaced by spineless cactus in the diet of lambs when this shows to be an ingredient with better cost-benefit ratio compared to wheat bran.
