粗甘油对生长猪生长性能、胴体性状及肉品的影响

通过一个为期138d的饲养试验来测定日粮中粗甘油对生长猪的生长性能,胴体性状,肉质指标和组织结构的影响。本试验使用的粗甘油包含84．51％甘油、11．95％水、2．91％氯化钠和0．32％甲醇。试验选用断奶8天后的仔猪共96头（48头公猪和48头母猪,平均体重为7．9±0．4kg）,按试验开始时的性别和体重分配到24个栏中（4头／栏）。日粮处理为玉米-豆粕型,     

Effect of cutting and vacuum cleaning on the digestibility of oats by horses

Three mature Quarter Horse geldings were used in 2 Latin square experiments to measure the effect of cutting and vacuum cleaning of oats on digestibility. The horses were fed at the maintenance level of digestible energy (DE) as recommended by the NRC.¹²The data were analyzed by Latin square analysis of variance, and Tukey's t test was used to determine any differences between specific means.No significant differences among treatments were observed during either experiment, indicating that the digestibility of nutrients from oats was not affected by cutting and vacuum cleaning. Differences in the digestibility of the ether extract (EE) fraction between periods of experiment 1 were noted.
