The pilot through three different types of diets five different hybrid cattle feeding trial,in hybrid cattle weight gain, feed consumption,NEmf,CP ntake,the results showed: Hybrid Beef types of diets and weight-related, When Feeding Concentrate+straw Diets(no diet Green materials) for ADG 1027.83g,Feeding Concentrate+weeds+straw diet(Dietary weeds) ADG of 1135.0g.Feeding Concentrate+Artificial grass+Alcohol ryegrass biological materials+straw diet (artificial grass diet) for the 1268.33g,ADG (P<0.05);FCR,Energy Eonversion Efficiency and PER to feeding the weeds+Concentrate Diets highest, respectively5.84, 29.13,1.66 than artificial feeding forage+Concentrate Diets high 12.74% respectively (5.84:5.18,P<0.01),64.36%(1.66:1.01,P<0.01) and 18.85% (29.1324.51,P<0.01);Fed rice straw+Concentrate diets were high 12.52%(5.84:5.19,P<0.01),2.47%(1.66:1.62,P<0.05) and 18.70%(29.13:24.54,P<0.01);Initial body weight, ADG associated with DMI, the regression formula is Y=-0.82+0.0128Xl+0.0034X2(R=0.7976,P<0.01);Initial weight,ADG NEmfI associated with the reunification formula:Y=-6.24+0.0429Xl+0.0228X2 (R=0.7450,P<0.05); nitial weight,ADG associated with the CPI,the regression formula:Y=-111.27+1.4099X1+1.4579X2 (R=0.7668.P<0.05);NEmfI,CPI accociated with ADG,the regression formula: =580.843+10.90Xl+0.271X2,R=0.8078,P<0.01);nergy conversion efficiency and NEmfI positively correlated (R=0.6781,P<0.05);Energy Eonversion Efficiency with little correlation between the CPI(R=-0.0407,P>0.05),PER with NEmfI,the CPI was negatively conelated.The regression equation: Y=2.6288-0.0114Xl-0.0010X2.So that the hybrid cattle fattening ration should be given the green fodder will be a good output, the weight gain of Hybrid beef with the DM,NEmf and CP intake related,In actual production should pay attention to the appropriate energy,protein supply for guarantee the growth of beef cattle, This test has been the regression formula to provide information that projection of Guizhou hybrid cattle fattening DM,NEmf,CP requirement of a day.
