Blood samples were obtained from 70 healthy gobra zebu from three different farms each one with a different feed (natural pasture, concentrates and groundnut hay) to exhibit the influence of type of feeding. To evaluate effect of poor pasture conditions, animals in an extensive system on natural pasture were sampled twice with a monthly interval in the late dry season. Blood samples were analysed for calcium, inorganic phosphate, total protein, glucose, urea, creatinine and haematocrit. Poor pasture conditions caused a decrease of plasma components such as haematocrit, total protein, inorganic phosphate, glucose and urea. The impact of type of feeding by comparing values from animals grazed on natural pasture with those from animals which received concentrates showed significantly higher values of total protein, urea and inorganic phosphate for animals fed with concentrates. Comparison between animals grazed on natural pasture and those which received groundnut hay indicate a significantly higher value of total protein and urea for animals fed with groundnut hay.
从三个不同农场的70头健康戈布拉瘤牛采集血样，每个农场使用不同的饲料（天然牧场、精饲料和花生干草），以展示饲养类型的影响。为评估贫瘠牧场条件的影响，在旱季后期，对天然牧场上粗放养殖系统中的动物每月采样一次，共采样两次。分析血样中的钙、无机磷、总蛋白、葡萄糖、尿素、肌酐和血细胞比容。贫瘠的牧场条件导致血浆成分如血细胞比容、总蛋白、无机磷、葡萄糖和尿素减少。通过比较天然牧场放牧动物与接受精饲料动物的值，发现喂食精饲料的动物总蛋白、尿素和无机磷的值显著更高。天然牧场放牧动物与接受花生干草动物的比较表明，喂食花生干草的动物总蛋白和尿素的值显著更高。
