病毒抗体含量的水平,同时提高阳性率(P<)。
(四)与对照组相比较,在血清中IgA含量方面,在母猪的基础日粮中添加一定量的CpG产品基本上不会影响母猪血清中IgA含量(P>);但是在断奶仔猪的基础日粮中添加CpG产品,会提升断奶仔猪血清中IgA的含量(P<)。
综上所述,在母猪和断奶仔猪的基础日粮中添加一定量的CpG 产品后,在不影响它们的肝、功能的情况下,可以能够提高母猪和断奶仔猪的生产性能和免疫效果。

The paper studied the effect of CpG on growth performance,physical and chemical indicators and immunization of SOWS and weaned piglets by adding certain amounts of CpG product(SOWS:%and %;weaned piglets:1%and %)into pig basic impacts on pig farm production benefits were also evaluation.
The results showed:
pared with the control group,change of total litter size,alive litter size,litter size at weaning,weaning weight or weaned piglet survival rate was non significant(P>).However, significantly positive impacts on feed intakes of SOWS were observed,as well as the piglet’S weight gain(P<).Non of weaned piglet illness(cough, asthma,diarrhea,weakness or death)occurred by CpG addition in basic diets(P>),neither the feed conversion ratio(FCR,P>).While the feed intakes and the body weight gains of weaned piglets shown
