秦川牛生长趋势分析

A Brief Introduction to the Growth Trend of Qinchuan Cattle

[目的]为了了解秦川牛的生长发育状况,[方法]通过对4~22月龄的秦川牛体重增重数据进行统计分析,并与其他品种牛的生长趋势进行对比。[结果]秦川牛在16月龄前生长速度较快,整体呈上升趋势,随着月龄的增长日增重呈下降趋势,其中9~16月齡日增重呈较快上升速度。与其他品种牛的生长趋势对比证明了秦川牛的生长速度及增重期更快、更长。[结论]针对秦川牛的不同生长阶段,精料喂量要与体重的增长成正比例增加,使其能够满足此阶段生长发育所需的营养需要,同时可以针对秦川牛优良的生长特性进行杂交选育,充分发挥其遗传资源的优越性。

[Objective] Understand the growth and development of Qinchuan cattle. [Method] A statistical analysis on the weight gain data of Qinchuan cattle from 4 months to 22 months was conducted and the growth trend was compared with other cattle breeds. [Result] The growth rate of Qinchuan cattle was fast up to 16 months of age, with an overall upward trend. Daily weight gain showed a decreasing trend with increasing monthly age, while daily weight gain from September to 16 months of age showed a rapid increase. Comparison with the growth trend of other breeds proves that the growth rate and weight gain period of Qinchuan cattle is faster and longer. [Conclusion] According to the different growth stages of Qinchuan cattle, the amount of concentrate in feed should be increased in direct proportion to the increase in body weight, so that it can meet the nutritional needs for growth and development at this stage. At the same time, crossbreeding can be carried out to obtain excellent growth characteristics of Qinchuan cattle to take a full advantage of their superior genetic resources.
