Abstract: ＂Zhangzagu＂ is a dominant hybrid foxtail millet species with advantages of high yield, water saving and impoverishment tolerance. Its straw can be developed as a source of forage and feed for animal feeding. The crude protein content of the straw of ＂Zhangzagu＂ is approximate 6.22%-7.35%. It is even higher in dough stage and reaches about 11.99%-13.34%, which is higher than that of other forage grasses. While the nutritive value of the straw of ＂Zhangzagu＂ is similar with alfalfa, its yield is higher than alfalfa. Foxtail millet contains abundant and balanced nutrition. A total of 8 essential amino acids are found in foxtail millet,except for lysine, the content of the other essential amino acids is all similar with that of egg. It is demonstrated by an amount of feeding experiments that the straw of foxtail millet can partially replace the foreign and native forage and straw as feed for breeding of sheep, bovine and rabbit. The application of ＂Zhangzagu＂ as a source of forage and feed is recommended to be widely extended in the regions where other forage is not suitable to cultivate due to drought, which may contribute to the grain production,development of animal husbandry and ecological protection in the new period.
