本研究旨在探讨适宜环境温度和高温环境对4个肉鸡品系生化指标的影响。选用商品代肉用雏鸡Ross、Hubbard、Cobb和Arber 4个品系，随机分为温中性区(TN)组和高温区(HAT)组，每组242只。TN组雏鸡在常温(25℃+2℃，相对湿度65+-5%)下饲养，而HAT组雏鸡在夏日的帽子下饲养。每组雏鸡进一步分为4个亚组，即TN-Ross、TN-Hubbard、TN-Cobb、TN-Arber Acer和Hat-Ross、Hat-Hubbard、Hat-Cobb、Hat-Arber Acer。每个亚群被进一步细分为四个重复，每个重复有十只雏鸡。分别于第21天和第42天采血。HAT组血清天冬氨酸氨基转移酶(AST)、丙氨酸氨基转移酶(ALT)、碱性磷酸酶(ALP)、血糖、胆固醇、甘油三酯和低密度脂蛋白(LDL)均显著高于HAT组(P<；0.05)，而TN组血清总蛋白和高密度脂蛋白(HDL)显著高于TN组(P<；0.05)。在TN区组，Cobb和Hubbard菌株的AST、ALT、血糖、胆固醇、甘油三酯和低密度脂蛋白显著降低(P<；0.05)，高密度脂蛋白和总蛋白显著升高(P<；0.05)。在HAT区组，Ross和Arber宏品系的AST、ALT、血糖、胆固醇、甘油三酯和低密度脂蛋白显著降低(P<；0.05)，高密度脂蛋白和总蛋白显著升高(P<；0.05)。研究结果表明，Ross和Arber两个品系比Cobb和Hubbard品系更耐受热带地区的夏帽，而Cobb和Hubbard品系在TN环境中更有效。
The present study was carried out to evaluate the effect of optimum and high ambient temperatures on biochemical parameter of four broiler strains. Broiler chicks (n = 242) of four different commercial strains (Ross, Hubbard, Cobb and Arber Acer) on day 15 were divided into two groups: thermo-neutral zone (TN) group and high ambient temperature zone (HAT) group. Chicks in TN group were housed at constant room temperature (25 degrees C +/- 2 degrees C and RH 65 +/- 5%) while chicks in HAT group were kept under HAT of summer. Chicks in each group were further divided into four subgroups, i.e., TN-Ross, TN-Hubbard, TN-Cobb, TN-Arber Acer and HAT-Ross, HAT-Hubbard, HAT-Cobb, HAT-Arber Acer. Each subgroup was further subdivided into four replicates having ten chicks per replicate. Blood was collected on day 21 and 42. Mean serum aspartate aminotransferase (AST), alanine amino transaminase (ALT), alkaline phosphates (ALP), glucose, cholesterol, triglyceride, and low-density lipoprotein (LDL) were significantly higher (P < 0.05) in HAT group, while total serum protein and high-density lipoprotein (HDL) were significantly higher (P < 0.05) in TN group. In TN zone group, significantly (P < 0.05) lower AST, ALT, glucose, cholesterol, triglyceride, and LDL and significantly (P < 0.05) higher HDL and total protein were recorded for Cobb and Hubbard strains. In HAT zone group, significantly (P < 0.05) lower AST, ALT, glucose, cholesterol, triglyceride, and LDL and significantly (P < 0.05) higher HDL and total protein were recorded for Ross and Arber Acer strains. The findings of the present study suggested that Ross and Arber Acer strains were more tolerant to summer HAT of tropical areas than Cobb and Hubbard, while Cobb and Hubbard strains were more effective in TN environment.
