适用肉牛不同育肥阶段全价日粮的研制

以肉牛在不同生长阶段的营养需求,利用甘蔗副产物为主要原料研究配制肉牛不同育肥阶段的全价日粮:以甘蔗梢叶和碱液处理的蔗渣作粗饲料;以糖蜜和玉米粉等作能量饲料;以花生麸或豆粕、菜籽粕等作蛋白饲料,以尿素、磷酸氢钙、石粉、菌种和预混料等为其它添加料,然后经生物发酵而制成。实验结果表明:与饲喂普通饲料相比,全价日粮不但营养搭配更科学合理,而且从饲喂效果看,肉料比更高,生产1 kg肉可减少23.8%~34.3%的成本。

Development of Adequate Diet at Different Fattening Stage of Beef Cattle

In this paper, sugarcane by-products was used as the main raw material for deployment of adequate diet at different fattening stage of beef cattle based on the nutritional needs of different growth stages: sugarcane leaves and bagasse with alkali treatment for roughage; molasses and corn flour for the energy feed; peanut bran or soybean meal, rapeseed meal for protein feed; urea, calcium hydrogen phosphate, stone dust, bacteria and premixes for other additives, and then the mixture was fermented to adequate diet. Compared with the general diet, the nutrition of adequate diet was not only more scientific and reasonable, but also the meat ratio was higher, and the cost of per kilogram meat production could be reduced by 23.8%~34.3%.
