Study On Growth And Immunity Of Growing Pigs By "Huangqi-Sanxian Compound Preparation"

In order to prove the effect of "Huangqi-Sanxian compound preparation" on growth,immune function, and pork quality on piglets,75pigs (Duroc×Landrace×Yorkshire) with anaverage body weight of20kg were selected and assigned into five groups(Control Group,TestGroup1,Test Group2,Test Group3and Test Group4) to investigate the effects on the growingcharacteristics, function quota of immunity and pork quality. The feeding trial was divided intotwo growing periods, the first period of piglets, test the effect of"Huangqi-Sanxian compoundpreparation" on piglet growth and immune performance; the stage of the second period of growingpigs, testing the effect of"Huangqi-Sanxian compound preparation" on pork quality impact. Thetest results indicated that:(1) Compared with Control Group, the average daily gain of Test Group1, Test Group2, TestGroup3and Test Group4were increased by-1.26％(P>0.05),6.61％(P>0.05),11.82%(P<0.05)and11.77%(P<0.05) respectively; The feed conversion ratio were decreased by-4.89％(P>0.05),2.45%(P>0.05),6.12%(P<0.05),4.89%(P<0.05) respectively; the daily intake increased with theincreasing of herbal feed additives; though there was no significant on the digest ration of thePhosphorus(P>0.05), when the dosing was0.3%, the digest ration of Calcium was significantincreased(P<0.05). The digest ration of crude fiber and energy of Test Group were increased by0.2%(P>0.05),1.4%(P>0.05),2.64%(P<0.05),3.6%(P<0.05) and0.7%(P>0.05),7.5%(P<0.05),11.4%(P<0.05),11.9%(P<0.05) than the control Group.(2) Compared with Control Group, Total protein increased by1.38%(P>0.05),2.03%(P>0.05),4.38%(P<0.05) and4.36%(P<0.05); Albumin increased by0.58%(P>0.05),3.48%(P>0.05),7.35%(P<0.05) and8.81%(P <0.05); IgM increased by0%(P>0.05),6.38%(P<0.05),12.76%(P <0.05) and14.89%(P <0.05); IgG increased by2.92%(P>0.05),5.30%(P<0.05),9.28%(P <0.05) and10.08%(P <0.05).(3) Compared with Control Group, the rib-eye areas and lean meat percentage increased by0.42%(P>0.05),3.26%(P>0.05),3.44%(P>0.05),3.97%(P<0.05) and2.22%(P>0.05),3.69%(P<0.05),4.61%(P<0.05),4.61%(P<0.05). The dressing percentage, mean BFT and muscle PHvalue were all no significant difference (P>0.05). The value of the marble veins in the Test Groupwere significant difference (P<0.05) compared with the Control Group. Based on the results of the test, it is suggested that "Huangqi-Sanxian compoundpreparation" can improve Growth performance Immunity and Pork Quality of Growing Pigs.Chinese herbal feed additives replace the traditional chemical synthesis of feed additives isentirely feasible, and has a significant advantage to a certain extent.
