BMY牛肩峰肉产量及肉质特性研究

目的]测定BMY牛肩峰的产肉量及分析其肉质特性.方法]对经过短期育肥至15月龄左右(平均15.0±0.52月龄)的24头BMY公牛进行屠宰,测定了其肩峰肉的重量和肉质特性,并从肌肉的肌纤维特征(肌纤维直径和肌纤维密度)、肉质(嫩度、pH值、失水率和系水力,以及熟肉率)、养分(初水分、肌内脂肪、粗蛋白和粗灰分)含量和...

Preliminary Report on the Beef Yield and Characteristic from BMY Cattle's Hump

【Objective】 Determined hump meat production of BMY cattle and analyzed meat quality.【Method】BMY bulls at the age of about 15 months(at the average age of 12.5±0.30 months) were slaughtered after short period of finishing determining the weight and characteristic of meat from their humps.And the meat quality of hump block was evaluated by comparing with high cuttings,Striploin and Outside plat which came from the same carcass,in aspects of myofiber characteristic(the diameter and the density of muscle fiber),meat quality(tenderness,value of pH,water loss and holding water capacity,cooking loss),nutrient composition(humidity,intermuscular fat,crude protein and crude ash) and scores from the taste panel evaluation of these cuttings’ muscle.【Result】Results of the rudimentary study indicated that BMY feeder stocks’ meat yield from the hump block was about four kilograms,with the ratio of about two percent of carcass weight,which was considerably appreciable due to the reason that BMY cattle had fifty percent of gene of Bos indicus.The meat quality of the hump block was good,and its taste and flavor were also good,which indicated that the hump block might be evaluated as high cutting of BMY cattle.【Conclusion】BMY hump meat was the better roast materials.
