Feeding a grower / finisher diet ad libitum from arrival in the breeding herd to puberty but delay mating until live weight and P2 targets are reached. 在进入种畜群后自由采食生长肥育猪日粮至初情期,但是要在活重(LW)或P2背膘厚达标后再配种。
Effects of Cellulase Additive on the Live Weight(LW) Gain and Feed Efficiency in Geese 日粮中添加纤维素酶曲对鹅增重及饲料利用率的影响
In order to find the key problems that have to be solved before slaughter in high quality beef production, the effects of breed, age and live weight on beef performance were investigated on the same feed plane. 为了确定在优质牛肉生产中所需解决的宰前关键问题,本文在相同饲养条件下,对品种、年龄及体重等因素对牛产肉性能的影响做了研究。
The body size and live weight of the F_1 crossbred of native yellow cattle with Limousin at the age of 6 and 12 month-old were determined to investigate the improving effects on native yellow cattle by Limousin. 为了研究利木赞牛对互助黄牛的改良效果,本试验测定了初生、6月龄和1岁利本F1代的体尺、体重,并与本地黄牛进行了比较。
The result indicated that the feeding level had significant effect on both quality and yield of beef, the live weight had significant effect on beef yield and effect of age on the both aspects of beef were neither significant. 结果表明,日粮水平对牛肉的品质和产量都有显著影响,活重(LW)对牛肉产量也有较显著影响,而年龄对肉质和产量均无显著影响。
