[국내논문]이유자돈의 사료 첨가제로서 Copper Chelates(메치오닌, 키토산, 효모)의 효과 Effect of Copper Chelates(Methionine-Cu, Chitosan-Cu and Yeast-Cu) as the Supplements to Weaning Pig Diet원문보기
본 시험은 이유자돈사료에 Cu-chelates를 첨사시 자돈의 생산성과 혈액지질 및 IgG 수준에 미치는 영향을 측정하기 위하여 실시하였다. 4주령 된 이유자돈 48마리(암 수 각 24마리)를 4처리 4반복으로 반복 당 3마리씩 암수 구별하여 실시하였다. 본 시험에서 사용된 대조구 사료에는 137ppm의 구리가 함유되어 있으며 각 처리구는 대조구사료에 methionine-Cu chelate, chitosan-Cu chelate와 yeast-Cu chelate를 Cu 100ppm 수준에서 각각 첨가하였다. 5주간의 사양기간 동안 증체량은 개체 단위로, 사료섭취량은 pen 단위로 매주 측정을 하였다. 일당 증체량, 사료 섭취량, 사료효율 그리고, 영양소 이용률은 모두 처리간에 유의차를 보이지 않았다. 혈청 내 triglyceride 함량은 chito- san-Cu 처리가 methionine-Cu나 yeast-Cu 처리보다 유의하게 낮았으나 대조구와는 유의한 차이를 보이지 않았다. 혈청 내 cholesterol 함량은 yeast-Cu 처리가 대조구와 methionine-Cu 처리보다 유의하게 낮았지만 chitosan-Cu 처리와는 유의한 차이가 없었다. 혈청 IgG의 함량은 대조구 보다 모든 Cu-chelate 처리구에서 낮게 나타났다. 결론적으로 Cu 137ppm의 대조구 사료에 Cu 100ppm 수준에서 첨가한 Cu-chelates는 이유자돈의 증체량, 사료섭취량과 사료효율에 유의한 영향을 미치지 않았으나, 혈청 내 지질의 조성과 IgG 함량에는 유의한 영향을 미쳤다.

An experiment was conducted to study the effects of the dietary Cu sources on the performance of the weanling pigs. Forty-eight, 24 in each sex, 4 weeks old pigs were assigned to four treatments; control, methionine-Cu chelate, chitosan-Cu chelate or yeast-Cu chelate. Control diet contained 136ppm Cu to which additional 100ppm Cu in different chelated form was added to the respective treatment. Individual pig weight and feed intake of each pen were recorded weekly for 5 weeks. Average daily feed intakes(ADFI), average daily gains(ADG) and ADFI/ADG were not significantly different among treatments. Nutrient availability was not also significantly affected by treatments. Serum triglyceride concentration of chitosan-Cu treatment was significantly lower than those of methionine-Cu and yeast-Cu treatments but was not significantly different from that of the control. Serum cholesterol concentration of yeast-Cu was significantly lower than those of the control and methionine-Cu but was not significantly different from that of chitosan-Cu treatment. Serum HDL-cholesterol concentration was not significantly affected by treatments. Serum IgG concentrations of all copper treatments were significantly lower than that of the control. It was concluded that Cu-chelates supplemented to the basal diet (136ppm Cu) by the level of 100ppm Cu did not significantly affect growth performance of weaning pigs. However, serum parameters of cholesterol, cholesterol and IgG were significantly affected by the treatments.
