Seasonal Variation in Erythrocytic Indices of Black Bengal Goats (Capra aegagrus hircus) in Purulia, West Bengal

Abstract: Being a multipurpose animal goat can produce meat, milk and hide. Purulia has a good number of Black Bengal goat populations, which has an important role in the lives of local goat rearers. The goal of the present study is to find out the effects of changing seasons on blood elements in Black Bengal goat (Capra aegagrus hircus) in Purulia of West Bengal. The highest mean value of temperature (ºC) has been reported during the month of April and May in the season of pre-monsoon. However, the lowest value of temperature (ºC) has been reported during the month of December and January in the season of post-monsoon. The parameter studied here are concentration of Hb, RBC count, PCV, MCV, MCH and MCHC. Data has analyzed for the effect of seasonal variation among both the sexes and the current findings implies that seasonal variation plays the major role to influence the erythrocytic indices.摘要：山羊作为多用途家畜，可提供肉、乳及皮张。普利亚（Purulia）地区拥有数量可观的黑孟加拉山羊种群，该种群对当地山羊养殖户的生计具有重要意义。本研究旨在探究西孟加拉邦普利亚地区黑孟加拉山羊（Capra aegagrus hircus）的血液指标随季节变化的影响。研究区域的平均气温在季风前季的4月与5月达到最高值，而在季风后季的12月和次年1月降至最低。本研究检测的血液学指标包括血红蛋白（Hb）浓度、红细胞（RBC）计数、红细胞比容（PCV）、平均红细胞体积（MCV）、平均红细胞血红蛋白量（MCH）及平均红细胞血红蛋白浓度（MCHC）。本研究针对不同性别个体的季节变化效应展开数据分析，结果表明季节变化是影响红细胞参数的主要因素。
