Chinese Abstract

隨著季節的變化,牧草生產改變著家畜食料及轉化攝取食料的能力,在春、夏、秋季綿羊食物的粗蛋白質含量分別高於草地牧草的15.99%、0.43%和2.71%。在冬季兩者的含量幾乎相等。但粗蛋白質食入量在春季比夏、秋、冬季分別多21.98%、40.40%和352%。幹物質食入量在秋季比夏、冬、春季分別多17.64%、38.33%和72.23%,從而導致冬、春兩季綿羊因食物不足而體重下降。

English Abstract

Dynamics of grazing ecosystem was about the interaction with plant and animal production, herbage output that changed with the season had effect on the animal feed and the capacity of transforming the food to animal nutrition. During the spring summer and autumn, the content of the herbage was separately more 15.99%、0.43% and 2.7% than of the grass lived on the land. However the protein content was lower in the winter. The protein intake in spring was more 22.3% of that during the summer. The protein content of herbage was the highest during the spring, but the DM intake of the sheep was fewer, which resulted in the loss of weight during the winter and spring.
