摘要
为了了解新疆不同气候条件下绵羊血液生理生化指标和免疫因子含量的差异,试验以南疆图木舒克和北疆北屯养殖区养殖的周岁多胎萨福克羊为研究对象,采集绵羊颈静脉血和养殖区的气象数据,应用全自动血液细胞分析仪测定16项血液生理指标,全自动生化分析仪测定9项血液生化指标,ELISA方法测定7种免疫因子含量,并对气象数据及各指标进行分析。结果表明:气温为两个养殖区的关键气候因子。北屯养殖区的多胎萨福克羊血液中嗜碱性粒细胞数、中性粒细胞数、嗜碱性粒细胞百分比、中性粒细胞百分比、单核细胞百分比、平均红细胞血红蛋白含量、平均红细胞血红蛋白浓度、血小板总数、平均血小板体积、血小板压积及γ干扰素、白细胞介素-1β、白细胞介素-12、白细胞介素-8含量均极显著高于图木舒克养殖区(P<0.01),单核细胞数和免疫球蛋白G含量显著高于图木舒克养殖区(P<0.05),丙氨酸氨基转移酶、胆碱酯酶、α-羟丁酸脱氢酶、乳酸脱氢酶活性及白蛋白、血清磷和血清铁含量极显著低于图木舒克养殖区(P<0.01)。说明气温可影响多胎萨福克羊血液生理生化指标和免疫因子,绵羊为适应干旱和高温的气候,血液中部分生理指标和免疫因子含量降低,生化指标含量升高。
In order to investigate the differences of blood physiological and biochemical indexes and immune factors in sheep reared under different climatic conditions in Xinjiang,in this study,the prolific Suffolk sheep were selected as the research objects in Tumushuke(southern Xinjiang)and Beitun(northern Xinjiang).Neck venous blood of sheep and meteorological date of breeding area were collected.The sixteen physiological indexes were measured by automatic hematology analyzer;nine biochemical parameters were measured by automatic biochemical analyzer,and seven immune factors were measured by using ELISA method.The meteorological data and the contents of indexes were analyzed by statistical method.The results showed that air temperature was the key climate factor in two areas.Basophilic granulocyte,neutrophilic granulocyte,basophilic granulocyte percentage,neutrophilic granulocyte percentage,monocyte percentage,mean erythrocyte hemoglobin content,mean erythrocyte hemoglobin concentration platelet,mean platelet volume,platelet pressure,γinterferon,interleukin-1β,interleukin-12 and interleukin-8 in blood of multiple Suffolk sheep in Beitun breeding area were extremely significantly higher than those in Tumushuke(P<0.01).Meanwhile,the number of monocyte and the contents of immunoglobulin G were significantly higher than those in Tumushuke culture area(P<0.05).However,the activities of alanine aminotransferase,cholinesterase,α-hydroxybutyrate dehydrogenase and lactate dehydrogenase and the contents of albumin,serum phosphorus and serum iron were extremely significantly lower than those in Tumushuke(P<0.01).The results indicated that air temperature could affect the contents of blood physiological and biochemical indexes and the immune factors of the prolific Suffolk sheep.In order to adapt to the climate of drought and high temperature,the contents of partial blood physiological indexes and immune factors in the blood of sheep were decreased,and the contents of blood biochemical indexes were increased.
