Effect of energy supplementation on the carcass and meat quality of cull cows of different ages and finished on cultivated winter pasture under temporary grazing

Effect of energy supplementation on the carcass and meat quality of cull cows of different ages and finished on cultivated winter pasture under temporary grazing

Revista Brasileira de Zootecnia 31(1): 173-182

The objective of this experiment was to study the effect of the different levels of energy supplementation on the carcass and meat qualitative characteristics of beef cull cows of different ages, under temporary grazing on cultivated pasture of ryegrass, (Lolium multiflorum), plus triticale, (Triticum). 40 Charolais cows were divided into four age classes: four, five or six, seven or eight and nine or more years, and randomly alloted to four levels of supplementation (SL): 0, 0.3, 0.6 and 0.9% liveweight. The supplement used was ground sorghum grain. No significant interaction was observed between supplementation level and cow age. SL did not affect meat colour, texture and marbling, neither carcass physical composition, meat sensory characteristics and thawing and cooking losses. With increasing age, there was a decrease in the muscle percentage at 68.5, 66.7, 65.1 and 64.3%, respectively. Young cows showed lower fat percentage (14.4%) than older animals, and showed a 17.9, 19.2 and 18.7% fat, respectively, for five or six, seven or eight, and nine or more years of age. Young cows had lower muscle+fat/bone relation than the animals slaughtered at an intermediate age. Cows slaughtered at four years showed a more tender meat (5.92 points) than cows slaughtered at seven or eight (4.69 points) years of age.
