果寡糖对固始鸡血液生理指标的影响

本试验旨在研究不同添加剂量的果寡糖对固始鸡血液生理指标的影响,并确定果寡糖的最佳添加剂量。选用1日龄固始鸡公雏150只,随机分成5个处理组,1个为对照组,其余4个为试验组,对照组不加果寡糖,其他4个组的果寡糖添加水平分别为3、5、7mg/kg和9mg/kg。测定红细胞压积(PCV)、血红蛋白(Hb)含量、红细胞数量、白细胞数量、平均红细胞体积(MCV)、平均红细胞血红蛋白含量(MCH)和平均红细胞血红蛋白浓度(MCHC)等指标。试验结果表明:1)21和42日龄时,果寡糖试验组的红细胞压积、血红蛋白含量、红细胞数量和白细胞数量均显著高于对照组(P<0.05);与对照组相比,试验组的MCH和MCHC均略有升高,并且可以显著提高MCHC(P<0.05);2)日粮中添加5mg/kg果寡糖对提高红细胞压积、血红蛋白含量、红细胞数量、白细胞数量、MCH和MCHC具有最佳效果。

Effects of fructooligosaccharide on blood physiological indexes in Gushi chickens

The present study was conducted to investigate effects of fructooligosaccharide(FOS)on the blood parameters of Gushi chickens.150 one-day-old male Gushi chicks were randomly divided into 5 groups.One group was control group,the others were experimental groups,control group was fed with basal diets,and experimental diets were basal diet added FOS 3,5,7 mg/kg and 9 mg/kg respectively.The press cell volume(PCV),the amount of red blood cell(RBC) and white blood cell(WBC),the concentration of blood hemoglobin(Hb),the mean corpuscular volume(MCV),mean corpuscular hemoglobin(MCH) and mean corpuscular hemoglobin concentration(MCHC)were examined.The results showed:1)The diet supplemented with FOS significantly enhanced the PCV,Hb concentration,amount of RBC and WBC and MCHC at 21 and 42 days(P < 0.05);2) At the level of 5 mg/kg,FOS enhanced the PCV,Hb concentration,RBC amount,WBC amount,MCH and MCHC(P < 0.05=.
