【摘要】：飼料桑蛋白質(zhì)含量高、氨基酸種類豐富、纖維素含量低,富含多種生理活性物質(zhì),是一種優(yōu)良的多年生飼料資源,對牛、羊、豬、兔、雞、魚等多種畜禽都具有很好的適口性。蛋禽日糧中添加桑飼料,可以顯著改善蛋黃顏色,提高蛋黃磷脂和不飽和脂肪酸含量,增加蛋清濃稠蛋白含量,改善蛋的風(fēng)味和品質(zhì)。肉類畜禽日糧中添加桑飼料,可以顯著改善肉品色澤,提高肌肉中肌苷酸和不飽和脂肪酸含量、減少膽固醇含量,降低肌肉滴水損失、延緩pH值下降及脂質(zhì)氧化變質(zhì),提高肉品質(zhì)量。牛、豬等大型肉類動物采食桑飼料后可減少皮下脂肪沉積,增加肌肉間脂肪含量,有效改善肉的品質(zhì)風(fēng)味。綜述了飼料桑中主要生理活性物質(zhì)的種類、含量、結(jié)構(gòu)特征、生理功能及其在畜禽養(yǎng)殖中的飼用價值;從生產(chǎn)性能和改善品質(zhì)方面分析總結(jié)了飼料桑在多種畜禽養(yǎng)殖中的應(yīng)用效果;提出了減輕抗營養(yǎng)因子不利影響、改善栽培利用效果的技術(shù)措施;展望了飼料桑開發(fā)應(yīng)用前景。
[Abstract]:Fodder mulberry has high protein content, rich amino acid, low cellulose content and rich in many physiological active substances. It is an excellent perennial feed resource and has good palatability for cattle, sheep, pig, rabbit, chicken, fish and so on. Adding mulberry feed to the diet of egg poultry could significantly improve the color of egg yolk, increase the content of egg yolk phospholipid and unsaturated fatty acid, increase the content of thick protein of egg white, and improve the flavor and quality of egg. The addition of mulberry feed to the diet of meat and poultry could significantly improve the color of meat, increase the content of inosine and unsaturated fatty acids in muscle, reduce cholesterol content, reduce the loss of drip, delay the decrease of pH value and the oxidative deterioration of lipid. Improve meat quality. After feeding mulberry feed to large meat animals such as cattle and pig, it can reduce subcutaneous fat deposition, increase intermuscular fat content, and improve meat quality and flavor effectively. The species, content, structure, physiological function and feeding value of main physiological active substances in feed mulberry were reviewed. The application effect of fodder mulberry in many kinds of livestock and poultry breeding was analyzed and summarized from the aspects of production performance and improving quality. The technical measures to reduce the adverse effects of anti-nutrition factors and to improve the effect of cultivation and utilization were put forward, and the prospect of development and application of fodder mulberry was prospected.
