Study On The Growing Function And Blood Physio-Biochemical Indexs Of Feed Rare Earths Additive Of The Weaned Xiang-east Black Goat

The paper studied by application statues of Rare Earths additive on production of animal science . The tests was adopted different dosage RE(NO3)3 in diet and studied on effect of different dosage additive on growing function and blood physio-biochemical of the weaned Xiang-east black goat. The conclusion might be the scientific basic for the more intensive applications of rare earths element in animal science field. First , twenty seven Xiang-east black goats were randomly and equally divided into three groups, group I, II Xiang-east black goat were fed the diets with 15mg/kg weight and 10mg/kg weight rare earths additive for experiment. Group III was control group and fed the diets (no rare earths additive ).ADGs FCR of the three groups had significant difference (P.O. 05). Group I, II economic benefit increased 12.9% and 8. 13% .Group I was higher i. 57% than group II. The results showed that the diets added 15mg/kg weight rare earths additive on fattening of Xiang-east black goat was higher.Second, studied on blood physio-biochemical indexes of feed rare earths additive of the weaned xing-east black goat. Glu , TL, NPN, TP, A, G . pH, Hb and GPT, GOT were measured, respectively. The results indicated that the test group II indexes was taller than the test group I except G, Hb .COT had significantly difference between two test groups. Other indexes had not significantly difference. Compare with control group TL, TP, A, G, pR. GPT, GOT had significantly difference (p<0.05)., but Glu.. NPN,Hb had not significantly difference(p>0. 05)between groups. Rare earths additive could improve the growing function of the weaned Xiang-east black goat through changed Glu, Tl, Tp in blood physio-biochemical indexes.
