D.2008年,每头奶牛年产奶约3吨

答案

参考答案:D

解析:
A项,按2008年的增长率,10年后,肉类总产量将达到111.52×(1+16.1%)10=496.22万吨,奶类总产量将达到197.65×(1+9.6%)10=494.31万吨,A正确;
B项,2007年蚕茧产量为3.35÷(1+11.0%)=3.02万吨,绵羊毛产量为0.37÷(1+8.2%)=0.34万吨,则蚕茧产量是绵羊毛产量的3.02÷0.34≈9倍,B正确:
C项,2007年家禽年末存栏量为5502.13÷(1+8.6%)=5066.42万,与牲畜年末存栏之比为5066.42:1712.85(由119题得)=2.96:1,C正确;
D项,2008年奶牛年末存栏数已知,但不能用牛奶产量除以该数来计算每头奶牛的年产奶量,D项错误。应选择D。
