摘要 | Forage supply of native grassland in Qinghai-Tibet Plateau reaches the greatest point in August and the lowest in the beginning of May. Feed intake of yak reached the greatest point in spring, followed by winter, and the lowest in autumn. Digestible CP (DCP) requirement (g/d) for maintenance in growing yak is 6.09 W(0.52), and that for gain is (1.1548/DG + 0.0509 W(0.52))(-1). There is a sever shortage of forage and CP supply in winter and spring. Grazing yak should be supplemented with 67.4 g/d DCP in the first cold season and 58.4 g/d DCP in the second cold season for normal growth. |
