摘要: 为探讨C3和C4植物在日粮中的含量对牛肉品质和主要化学成分的影响,本试验选用大豆粕、小麦麸、小麦、棉籽饼、苜蓿干草作为C3植物试验材料,选用黄贮玉米秸、玉米酒精糟、玉米作为C4植物试验材料,选用36头西门塔尔杂种公牛作为试验动物开展了肥育和屠宰试验。结果表明,日粮中C4植物含量对肥育牛增重、牛肉的脂肪酸、氨基酸(其中甘氨酸不确定除外)、水分含量以及牛肉的剪切力、蒸煮损失率、滴水损失率、大理石花纹评分和眼肌面积均没有显著的影响。日粮中C3植物含量对肥育牛增重、牛肉的脂肪酸(其中十七烷酸不确定除外)、氨基酸(其中丝氨酸和苏氨酸不确定除外)、水分含量以及牛肉的剪切力、蒸煮损失率、大理石花纹评分和眼肌面积也均没有显著的影响。

Abstract: In a fattening trial and a slaughter test of 36 Simmental crossbred bulls, C3 plant components (soybean meal, wheat bran, Triticum aestivum, cotton seed meal and alfalfa hay) and C4 plant components (corn stalk silage, maize alcohol lees and Zea mays) were compared to evaluate their effects on the quality and main chemical components of beef. There were no significant effects of dietary C4 plants on the growth rate of beef cattle, the contents of fatty acids, amino acids, moisture, the shear force value, cooking loss, drip loss, marbling score and eye muscle area of beef. Similar results were obtained with dietary C3 plants.
