摘要
本试验采用食道瘘管法和植物显微技术镜检法对放牧绵羊采食的植物成分进行了测定,结果表明,绵羊对牧草的偏嗜性在不同类型的草场和不同生长期表现为不同,但对某些牧草的偏嗜是比较确定的。绵羊对柔嫩的阔叶草和小禾草表现为极偏嗜,而对某些优势种表现为不乐意采食。
The methods of esophagus fistula method and microscopic examination technique were adopted to determine the botanical composition of forage samples selected by grazing sheep. Results show that partiality for a particular kinds of forage grasses of sheep varies in different types pasture and different season,but the partiality of sheep to grasses is relatively definite. Sheep to relatively tender broadleaf grasses and small grasses show strong partiality for what they graze,and they dislike to graze some dominant species.
