Effect of Japanese Cedar charcoal as feed additive on blood profiles in growing sheep

(1)用特制的杉木炭（JC）和活性炭（AC）口服生长绵羊，饲喂精料日粮。红细胞no。AC组增高。白细胞号。， JC组降低，AC组升高。AC组雄性阉割后中性粒细胞比例有增大的趋势，而JC组雌性阉割后中性粒细胞比例有减小的趋势。JC组总胆固醇偏高，AC组总胆固醇偏低。JC组和AC组ALP活性呈升高趋势，AC组CPK呈升高趋势。JC组和AC组GSH-Px呈高水平。(2)使用有机溶剂洗涤的JC，观察到血液特征相似。JC组ALP和SOD活性较低。母羊各组各组血红蛋白单位GSH-Px在饲喂前呈低趋势，饲喂后呈高趋势，AC组呈低趋势。

(1) Specially prepared Japanese Cedar charcoal (JC) and activated charcoal (AC) were orally administered to growing sheep which were fed on concentrate-based ration. Red blood cell no. was increased in AC group. White blood cell no. was decreased in JC group of castrated male, while it was increased in AC group. Neutrophil ratio for AC group of castrated male tended to be larger, however in female, JC group showed a lower tendency. Total cholesterol tended to be high in JC group, but low in AC group. ALP activity showed higher tendency for JC and AC groups and CPK in AC group showed higher tendency. GSH-Px tended to be high in JC and AC groups.(2) Using the JC washed by organic solvent, the similar blood characteristics were observed. However, ALP and SOD activities tended to be low in JC group. GSH-Px per unit of haemoglobin in JC group tended to be low before feeding, however high after feeding and AC group showed the lower tendency in female sheep.
