【摘要】 通过对山羊在灌丛草地春、秋季放牧的日采食量、采食率、牧草消化率及消化能的研究,表明春季山羊的日采食量、采食率高于秋季;随着牧草的粗纤维含量的增加,山羊对各种营养物质和能量的消化率及消化能呈有规律下降的趋势.更多还原

【Abstract】 This paper reported the goat’s daily-consumption uptake rate、forage digestion rate and digestable energy (DE) in spring and autumn. The results show that the goat’s dailyconsumption and uptake rate in spring are higher than those in autumn. As the crude fiber content of forage increases, goat’s digestion rate and DE of nutritive materials and energy show reduction tenddncies.更多还原
