摘要
将２４头盘江黄牛和１２头西本杂牛分为１２个组，采用不同的日粮配方，进行两次肥育试验，得到不同的增重水平和实际营养物质摄入量。用各组实际采食的干物质（ＤＭ）、粗蛋白（ＣＰ）、综合净能（ＮＥｍｆ）与我国试行的《肉牛饲养标准》进行比较。结果表明，除干物质与标准相差较多（－６．３％）外，粗蛋白和综合净能与标准相当接近（仅相差－１．５％和＋２．８％），说明盘江黄牛及其杂交牛在肥育中的营养需要与标准基本相符，在配制日粮时，可以参考我国的《肉牛饲养标准》。
Panjiang cattles and 12 Xiben cross cattles divided into 12 groups were fattened with different diet formula to be tested for two times and then the different gain levels and actural nutrient absorption were known. Compared the national trial implementation standard of beef cattle feed with the actural DM, CP, NEmf for Banjiang cattle snf its cross, CP and NEmf is close to the standard (only difference -1.5% , 2.8% ), except for DM (Difference -6.3%). The results showed that the national standard could be referred to fattening Banjiang cattle and its cross.
