STUDY ON THE EFFECT ON PIG-REARING WITH FERMENTATION BEDS OF DIFFERENT PADDING
摘要
Abstract
(Purpose) In order to that ascertain the effect on immune function and growth performance of pigs was studied fermentation beds of different padding. (Methods) 40 pigs were randomly divided into 4 groups, each group included 10 pigs. The first group is the feeding group with the fermentation beds of using crushed corn stalks mainly ( corn stalks group) ; Group 2 is the feeding group with fermentation beds of using peanut - shell mainly (peanut - shell group); Group 3 is the feeding group with fermentation beds of using sawdust mainly (sawdust group); The forth group is the feeding group with conventional concrete floor (control group). Eachgroup was injected with swine fever vaccine, PRRSV vaccine and swine pseudo -rabies vaccine, and was fed with according to conventional breeding methods. The experiment lasted 60 days. Rate of weight gain of each pig, serum antibody positive rate, γ - IFN and IL - 4 levels, hemoglobin in the blood and the total number of lymphocytes and erythrocytes were determined at the end of experiment. ( Results) The results indicate that when fed to the 60 days, the rate of weight gain of pigs in the group 1, group2 and group 3 were higher than the controlgroup. The higher rates were separately 4.66% , 7.16% and 3.56%. And the difference was significant (P < 0.05). The antibody positive rate of pigs in group 1, group 2 and group 3 were higher than control group. The difference of group 1 was not significant, and the difference of group 2 and group 3 was significantly different (P <0.0001). The blood hemoglobin content, red blood cell volume and the total number of lymphocytes in group 1 were lower than the control group, and these of group 2 and 3 were both higher than the control group. And there was no significant difference. The levels of γ - IFN and IL -4 in pig serum of group 1, group 2 and group 3 were higher than the control group. But there was no significant difference. (Conclusion) Compared with thefeeding group with the conventional concrete floor, the feeding groups with fermentation beds of using different padding all can improve pig growth performance and immune effects. And the fermentation beds of using com stalks and peanut shells can significantly improve pigs'rate of weight gain growth and feed utilization. A theoretical basis and technical support of extension and application with the technology of rearing pigs with fermentation beds was provided by the results of the study.关键词
