The Synthsis Of Glycine Iron And The Influence Of Weaning Piglets Growth Performance

This experiment using glycine and ferrous sulfate as the main raw material synthesis glycine iron,the best condition combination is studied,in order to Synthesis of glycine iron.Comparative extracting agent effect,Choose ethanol extracted synthetic products glycine iron,The iron in glycine synthesis as glycine iron rate synthetic test index.Then using synthetic glycine iron feeding weaning piglets,Studied glycine iron weaning piglets growth performance,health and waste the influence of Fe content. This research mainly is divided into two parts test results,the results of their study as follows:Experiment.1Glycine iron synthesis conditions optimized combination test This experiment is determined antioxidants BHA of additives for glycine15%(Moore quantity) and the glycine iron synthetic reaction time for100min,The test uses three level four factors of orthogonal experiment design, Research glycine iron synthesis temperature,pH,molar ratio,glycine glycine iron concentration of the influence of synthetic yield.The orthogonal experiment results show,Glycine iron synthesis of impact factor size is as follows:The reaction medium pH,reaction temperature,molar ratio of reactant between,reactants glycine concentration.Glycine iron synthetic optimal combination conditions is:pH is4.5,Reaction temperature is55℃, reactants Moore ratio is1:1,reactants glycine concentration is6%.Experiment.2The influence of adding glycine iron diet feed on weaned pig productivityIn order to study the effect of on the growth performance of weanling piglets on basal diet addition50ppm (including ferrous iron) iron-gly,72weaned piglets are selected to be randomly divided into3groups,Every group sets up3repetitions, and8piglets in each repetition. For experiment,there are contrast group I(basic diet including100ppm inorganic iron), contrast group II (basal diet addition50ppm inorganic iron),test group(basal diet addition50ppm iron-gly).For experiment,there are contrast group I,contrast group II,test group.Test results show that more over contrast group I and II, not significant difference,the daily gain of the test group is2.67%(P>0.05)and2.18%(P>0.05) In feed/gain rate,contrast group I and II are no significant difference compared with test group,feed/gain rate decreases by1.4%(P<0.05)and0.7%(P>0.05)over contrast I and II In diarrhea rate,Diarrhea rates compared with the control groupI and II decreased93.3%and83.3%breeding rate was not significant difference between the three groups.Serum microelement iron trend of increase are higher than the control group I and control group II, Achieve significant difference (P<0.05),the test group of weanling piglets excretion is30.02%(P<0.01)and30.47%(P<0.01),test group is extremely significant difference between control group I and control group II(P<0.01) In the experiment of the first28d,the test group of weaning piglets IgA concentration between group I and II are significant difference(P<0.05),the test group of weanling piglets IgA excretion is12.4%and10.3%than the control group I and the control group II．...
