| study was conducted to investigate the effects of micro-mineral amino acid chelate and inorganic micro-mineral on growth performance and serum physilogical biochemical parameters of goat. 30 castrated nanjiang yellow goats were randomly allotted to five treatments :(1)basal diet (2)high level treatments: the basal diet + amino acid chelate micro-mineral (80ppmFe, 100ppmZn, 20ppmCu, and 120ppmMn); (3)middle level treatments: the basal diet + amino acid chelate micro-mineral (80ppmFe, 40ppmZn, lOppmCu and 60ppmMn); (4)low level treatments: the basal diet + amino acid chelate micro-mineral (20ppmFe, 25ppmZn, SppmCu and 30ppmMn); (5)the basal diet + feed grade sulfate (80ppmFe. 40ppmZn, 8ppmCu and 60ppmMn) with 2 replicates of 3 goats. The results showed: (1)low level treatments was the best of all groups in increasing performance. In contrast to feed grade sulfate.increased average daily gain(ADG)15.89%(P < 0.05), feed conversion rate(FCR)12.73%(P < 0.05). In contrast to basal diet group, increased average daily gain(ADG)25%(P < 0.05), feed conversion rate (FCR) 24.15%(P < 0.05). that showed micro-mineral amino acid chelate are superior to inorganic micro-mineral in improving performance of goat.(2).The same level of micro-mineral amino acid chelate has no effect on significant on serum TP, ALB, GLOB, GLU, TG, BUN, ALT, AKP, LDH, Ca, P, Mg, Fe, Cu, Zn in conpaision to feed grade sulfate. content of serum Fe, Cu, Zn, AKP, LDH, GLOB, Ca, P would appear a tendency of increasing with improvement of supplement of micro-mineral amino acid chelate. When 0.5 AFRC supplement of micro-mineral amino acid chelate, content of serum Fe, Cu, Zn reached or surpassed that of supplement sulfate.3.Contents of wool trace mineral were affected by level of supplement of micro-mineral amino acid chelate. (P < 0.1).There is significant quadratic corelationship between ADG and Mn . There is significant corelationship between Fe,Cu,Zn content of wool and that of serum.It is suggested that micro-mineral amino acid chelate have the function of improvingperformance and advancing the nutrition condition of goat. |
