This paper discusses the chicken plasma protein powder weaning growth performance, cellular immunity and energy metabolism in the impact of regulation, including two tests. Test: Different Sources of plasma protein powder on the performance of weaned pigs. 48 28 d weaning DLY piglets were randomly divided into three groups, each group of four repeats, each repeated four pigs. Dealing with a control group (basal diet), processing and handling 3 respectively in the control group on the basal diet with 7.5% chicken plasma protein powder and 5% of swine plasma protein powder instead of part of the protein by nitrogen, such as the principle of proportional mode the preparation of the experimental diets. Test 1-14 d were fed the experimental diets, 14 days after the change to feed the same post-diet until the end of the 28-day trial, a trial period of four weeks. Digestion test in the first 7 - 14 days, feces collection 3 d, according to conventional feeding and management. Test: The chicken plasma protein powder on early weaned piglets immune function and energy regulation; piglets each test 0, 14, 28 the test a basal diet group and 7.5% chicken plasma protein powder group with similar weight 8, venous blood by centrifugation, the serum for determination of immune-related indicators; at the end of the test, each selected from the test group similar body weight piglets piglets each 4, slaughter test the liver Determination of energy metabolism related indicators. The results show that: (1) the test 1-14 d Add chicken plasma protein powder can improve the performance of weaned piglets for the various phases of production. In the pre-test (1-14 d), compared with the control group, the chicken plasma protein powder group ADG was significantly increased by 37.11% (P <0.01), ADFI significantly increased by 65.07% (P <0.01), F / G significantly reduced 16.42% (P <0.01). Chicken plasma protein powder group compared with the porcine plasma protein powder group ADG, ADFI, improve 9.09%, 16.79%, F / G decreased by 5.62%; test late (14-28 d), chicken plasma protein powder group piglet. the control group was significantly improve 27.27%, F / G (feed conversion ratio) 7.88% (P <0.01) significantly reduced, swine plasma protein powder group ADG than the control group increased by 17.92%, feed conversion ratio decreased 4.92% (P <0.01). Chicken plasma protein group, the average daily gain, respectively, than pig plasma protein group increased by 4.4% (P> 0.05) in the test period (1-28 d) compared with the control group was significantly increased by 22.47% (P <0.01) ; chicken plasma protein powder group F / G, compared to the porcine plasma protein powder group reduced by 4.26% (P> 0.05), compared with the control group was significantly reduced by 11.33% (P <0.01). (2) test the first 14 days, chicken plasma protein powder group piglets blood IL-1 (white referral prime -1) concentration compared to the control group significantly reduced 8.80% (P <0.05), than the control levels of IL-4 (White mediated prime -4) of group was significantly improve 21.70% (P <0.01), IL-1ra (White mediated prime -1 receptor inhibition of protein) of the levels compared with the control group a very significant 23.73% (P <0.01); test the first 28 d, IL-1 concentration were decreased by 17.90% (P> 0.05), the level of IL-4's than in the control group increased by 16.96% (P> 0.05), IL-1ra levels than the control group increased by 6.78% (P> 0.05). Add chicken plasma protein powder improved humoral immune function of weaned piglets. Chicken plasma protein powder piglet serum IgM compared with the control group increased by 14.44% in the test the first 14 days, the first 28 days of the test, serum IgG compared with the control group increased by 20.45%. (3) Add the chicken plasma protein powder to improve the the piglets energy digestibility. Wherein the liver Na to K to-ATP enzyme has significantly improved (P <0.05) compared with the control group; compared with the control group, the liver of chicken plasma protein powder group F-1 ,6-BP-1 (fructose-1, 6 - bisphosphatase) and 6-PF-1K (6 - phosphofructokinase) were significantly increased (P <0.05). Chicken plasma protein powder group energy apparent digestibility improve the 4.48% compared with the control group. In summary, the results of this study show that: Add chicken plasma protein powder and promote growth performance is superior to porcine plasma protein powder, this may reduce the plasma protein powder and add chicken weaned piglets degree of immune activation, regulation of energy metabolism.
