Effect Of Soluble Fish Protein Concentrates Substitute Blood Plasmatic Protein Powder To Weaning Piglets On Performance, Nutrition Digestibility And Serum Biochemical Parameters

The experiment was conducted to investigate the effects of fish protein concentrates substitute blood plasmatic protein powder on performance, diarrhea frequency, apparent digestibility, feces density of various bacterial populations and the physiological and biochemical parameters in blood in the diets of young weaned piglets.In this experiment we choose 26~28 days old, 96 weaned piglets(Duroc X Landrance× Large) which were divided into four groups and every groups had three pens which had eight piglets. Group I was contrast group, II , III, IV was experiment group, group I adds to 3% plasmatic protein powder, group II adds to 2% plasmatic protein powder+1% soluble fish protein concentrates, group III adds to 1% plasmatic protein powder+2% soluble fish protein concentrates, group IV adds to 3% soluble fish protein concentrates.the experiment was 28 days,the first 14 days was the first phase,after 14 days was the second phase.The results showed:1.Soluble fish protein concentrates substitute blood plasmatic protein powder. The intake,experiment group increased 0.29%, decreased 0.38%, 1.94% respectively. The difference among all the experimental group was not significant. The average daily growing, the experiment group reduced 0.91%, increased 0.84 % , reduced 0.79 % respectively. The difference among all the experimental group was not significant.2.Nutrition digestibility. Nutrition digestibility was decreaced,the experimeng II group decreaced, but III, IVgroup increased. The difference among all the experimental group was not significant.3.The total counts of coliform bacteria of feces decreased. The experiment group reduced 2.71%, 4.19%, 7.15%respectively. The difference among all the experimental group was not significant. And the counts of ? Lactobacterium increased. The experiment group increased 3.21%, 5.83%, 7.74%respectively. The difference among all the experimental group was not significant.4.The diarrhea frequency was decreaced, The experiment group decreaced 17.95%, 25.64%, 33.33% respectively. The difference among all the experimental group was not significant.5.The count of RBC increased, The experiment group increased 5.31 %, 6.48%, 11.30 % respectively.The" difference among all the experimental group was not significant. The count of HGB increased, The experiment group increased 1.99%? 5.17% , 9.99%respectively. The difference among all the experimental group was not significant. The count of WBC decreaced 4.25 %, 8.44%, 14.85% respectively. The count of lymph cell increased, The experiment group increased 1.78%, 5.30%, 6.79 % respectively. The difference among all the experimental group was not significant.6.T3, the experiment group decreased 2.22%. increased 2.22%, decreasedl.il % respectively. T^ the experiment group decreased 2.18%, decreased 1.17%, increased 1.30% respectively. The difference among all the experimental group was not significant.7.TP of the plasma increased, the experiment group increased 8.77%, 10.53%, 12.28% respectively. ALB of the plasma increased, the experiment group increased 13.97%, 15.66%, 19.27% respectively.Globin of the plasma increased, the experiment group increased 29.72%(P<0.01). 36.58%(P<0.01). 42.60%(P<0.01) respectively. IgA of the plasma increased, the experiment group increased 29.41 %(P>0.05), 35.29%(P>0.05), 47.06%(P<0.01)respectively. IgG of the plasma increased, the experiment group increased 23.26%(P>0.05) , 32.56% , 40.00%(P < 0.01 = respectiveLy.IgM of the plasma increased, the experiment group increased 52.00%(P>0.05), 68.00%(P>0.05), 96.00% (P<0.01)respectively.
