The summary is research new-style zinc additive - egg ammonia acerbity chela adds up to zinc to be reached to the nutrient effect of chickling discuss inside source zinc eduction measures determine method, had two tests: Experiment Ⅰ , the 11 day age after be being absorbed adequately with yolk bursa bank white chicken fair cheeper is experiment animal, individual raise. With corn - soja depart albumen half pure add up to ration to be a foundation (the 23.5mg/kg that contain zinc) . With 4 reduplicative design of 4 2 factor studied 4 × different zinc compound - vitriolic zinc (ZnSO4) , egg ammonia acerbity chela adds up to zinc (Ⅱ ) inside complex salt (ZnMet2) with cation of subsidiary channels in the human body through which vital energy (ZnMet22) , zincic treasure 100 (Zinpro100) reach different zinc adds a level, 15, 30, 60mg/kg) to zinc the deposit inside chickling body uses the influence that reachs pair of chickling to grow. Experiment Ⅱ , the gallinaceous feed true metabolizable energy that uses Sibbald is fast mensuration (TME law) and the law is inserted to study 12 Zhou Ling's cocks are right outside maths of zinc absorb and excrete a circumstance. The result makes clear: Zincic source collects weightening finish of appetite, body, weightening finish to chickling / deposition of zinc of body of chroma of the zinc in bad news makings, blood and liver, chicken, feed zinc deposit rate is not had showing an effect (P>0.05) , but the trend that all shows ZnMet2 and Zinpro100 excel ZnMet22 and ZnSO4. Zincic cause is basic to chroma of the zinc in tibial He Yiyu and serum phosphoric acid is enzymatic (AKP) active effect is distinct (P<0.05) . Like what try chicken with ZnSO4 group tibial in zincic chroma is 100% , criterion the relative value of group of source of 3 kinds of zinc is ZnMet2, ZnMet22 and Zinpro100 each 123% , 109% with 134% . The zincic deposit rate inside the chickling body of different zinc source and be in tibial in pattern of growth and decline of zincic pH indicator is consistent. With ZnSO4 group chickling feed zincic deposit to lead 100% , criterion ZnMet2 is 106% , znMet22 group is 100% , zinpro100 group is 112% . The biology utilization rate of compound of 4 kinds of zinc is Zinpro100>ZnMet2>ZnMet22 >ZnSO4 by sort of on any account. Add with do not add zinc to collect weightening finish of appetite, body to have distinct effect to chickling (P<0.01) . To corn - soja depart albumen half pure add up to ration adscititious zinc 30mg/kg (total Zn53.5mg/kg) grow what above can satisfy the chickling below this experiment condition normally. Chroma of the zinc in blood compares stability relatively. Chroma of the zinc in alar feather, tibial, liver, the metabolic response that serum AKP active and gallinaceous body deposition measure to eating zinc is sensitive, show strong positive to close, and feed zincic deposit rate to be followed however lift and drop what eat zincic amount apparently (R=-0.65** ) . The live system that reason can use chroma of the zinc in alar feather to regard an evaluation as state of chickling zinc nutrition diagnoses index, yi Ke regards the biochemistry of this evaluation as index with serum AKP active. This experiment is measured corn - soja depart albumen half pure close model the true utilization rate of the zinc in ration is 20.40% . The zincic true utilization rate of the ZnSO4 that reachs on this foundation and ZnMet2 the origin of parameter of zincic eduction quantity is different and Yineiyuan is different. When the parameter of zinc of the source inside each that with hungry platoon the empty law, oneself that be the same as chicken discharges empty law and law of the ration that do not have zinc to be measured is corrective, the zincic true utilization rate that gets ZnSO4 respectively is ordinal for 26.33% , 20.03% with 48.84% ; ZnMet2 is 63.33% , 37.38% with 86.77% . The law is inserted to reach the zincic true utilization rate of ZnSO4 is outside using maths 37.01% , znMet2 is 99.07% . Visible, as a result of inside the difference of parameter of quantity of source zinc eduction, the wave motion of zincic true utilization rate of source of two kinds of zinc is very big. The research that consequently short-term and quick TME way uses at microelement utilization rate cannot be taken. Income data also can serve as reference only. But be opposite in chicken of zincic source use a field, egg ammonia acerbity chela adds up to zinc apparent excel is vitriolic zinc this can affirm.
