| 摘 要： | 以雏鸡对锌的利用率、沉积率和组织中的锌浓度为指标,评定了不同来源的锌(硫酸锌、氧化锌、氯化锌、乙酸锌、硝酸锌、葡萄糖酸锌、小麦麸、米糠、玉米糠、谷糠)的生物效价。结果表明,锌的生物效价不仅与锌的来源、形态有关,而且受饲粮锌水平的影响。无机化合物锌的生物效价均高于植物饲料锌。

| Abstract: | Bioavailabilities of various zinc sources (sulfate, oxide, chloride, nitrate, acetate, gluconate, wheat bran, rice bran, corn bran, millet bran) in broilers were studied by means of zinc utilization , Zinc retention, Zinc concentrations in some tissues. The results showed that significant differences were found in bioavailabili- ties among various zinc sources and also zinc levels had much effect on it,Bioavailability of zinc in inorganic compounds were higher than ones from plant sources. |
