| Probiotic is a kind of active microbial agents, it as a new type of feed additives, is non-toxic, no sideeffects, and promote animal growth, improve the feed conversion rate, enhance animal immune function etc,at present has been widely used in livestock and poultry breeding industry. This paper first chaptersummarizes the research progress of probiotics, action mechanism and application status in pig production,in order to provide the reference for the research and production. Test in xinjiang turpan city fengyuanjia-min breeding pig co.LTD. The experiment was condueted to study the effect of the same dietaryEcological composite probiotic supplementation on growth and hog Performance. Select physical, age,health degree similar weaning piglets DuLuoKe, Yorkshire and white110head and136head growthgrowing and fattening pigs, randomly divided into experimental group and the control group; In the sameraising the management level, the two groups of basic ration is consistent, pig experimental group in thebasic food, adding more than0.35%ecological composite probiotic, fattening experimental group add morethan0.32%ecological composite probiotic. Weaning piglets test results show that the experimental groupand the control group in the middle of test (1-16d) body weight, body length difference was significant (P <0.01), The daily body weight gain was increased by52.17%on average; body weight and body length wasPromote in the end（17-33d）(P <0.01), average daily weight increased by20.93%. The results showed thatIn experimen0f hot was Promote in the middle of test (1-48d) body weight and body length between withexperiment group and compare group (P <0.01); It’s the same as usual as the end (49-98d).The daily bodyweight gain was increased by14.7%on average. Explain many ecological composite probiotic can reducethe incidence of piglets, improve the growth rate; And improve education growing pig weight, reduce feedweight ratio, improve pig environment. |
