Abstract：
The current study examined the growth rates, carcase characteristics, meat quality, and consumer sensory evaluation of the longissimus lumborum muscle (striploin) from steers that were supplemented with either canola meal or grain-based pellets. Forty Angus and Hereford × Angus steers received one of these two supplements with ad libitum lucerne hay for 60 d prior to slaughter. Average daily weight gain was not affected by dietary treatment; however, hot standard carcase weight was significantly lower for steers offered canola meal compared with steers on the grain-based pellets. Dietary treatment did not affect the carcase characteristics, meat quality traits, and consumer sensory evaluation, irrespective of ageing periods. Therefore, canola meal can be used as an approved Pasturefed Cattle Assurance System (PCAS) supplement on moderate dry quality forages without negatively affecting carcase and meat quality traits.
摘要：
当前的研究检查了增长率，carcase特性，肉质,和消费者对补充了低芥酸菜籽粉或谷物颗粒的牛背肌（striploin）的感官评估。40名安格斯和赫里福德×安格斯牛在屠宰前60天接受了这两种补品中的一种，并随意服用了卢塞恩干草。平均日增重不受饮食处理的影响；然而，与以谷物为基础的颗粒上的牛相比，提供油菜粉的牛的热标准牛壳重量显着降低。饮食治疗不影响carcase特征，肉质性状，和消费者感官评价，不论老化时期。因此,油菜籽粉可用作中等干质量牧草的经批准的糊状牛保证系统（PCAS）补充剂，而不会对carcase和肉质性状产生负面影响。
