The study was conducted to investigate the effects of feeding different levels of dried cassava leaves at 0%, 20%, 40% and 60%, respectively, using guinea grass as basal feed, on the haematological and serum biochemical parameters of West African Dwarf (WAD) goats. The study lasted for 116 days during which haematological and serum biochemical parameters were monitored in 40 male goats before and after, using a completely randomized design. At the start of the experiment, packed cell volume (PCV) ranged from 21.5% to 25.5% while haemoglobin concentration (Hb) and RBC significantly (P < 0.01) ranged from 7.3 to 8.6 g/dl and 10.4 to 13.2 × 10(12)/l, respectively. White blood cells reduced significantly (P < 0.05)) from 16.4 to 11.7 × 10(9)/l) as dried cassava leaves increased in the diets. At the end of the trial, there was a slight increase in the values of PCV and Hb in the diets (P > 0.05). Lymphocyte reduced significantly (P < 0.05) from 50.0% to 63.5% in the diets. Neutrophils, however, increased (P > 0.05) at the 0% to 40% levels and reduced at the 60% level of dried cassava leaves inclusion. At the start of the experiment, values for glucose significantly (P < 0.05) ranged from 40.1 to 56.0 mg/dl. Total protein and albumin values ranged significantly (P < 0.05) from 56.0 to 68.5 g/dl and 30.6 to 38.4 g/dl, respectively. At the end of the experiment, serum creatinine increased significantly (P < 0.05) as the level of dried cassava leaves increased from 0% to 60% in the diets. The study revealed that inclusion of dried cassava leaves in the diets of West African Dwarf goats had no deleterious effects on the haematological and serum biochemical parameters of WAD goats and could therefore be included in ruminant diets up to 60%.
本研究旨在探讨以几内亚草为基础饲料，分别添加0%、20%、40%和60%不同水平的木薯干叶，对西非矮山羊（WAD）血液学和血清生化参数的影响。研究持续了116天，在此期间，采用完全随机设计，对40只雄性山羊的血液学和血清生化参数进行了前后监测。实验开始时，红细胞压积（PCV）范围为21.5%至25.5%，而血红蛋白浓度（Hb）和红细胞（RBC）显著（P < 0.01）分别为7.3至8.6 g/dl和10.4至13.2×10(12)/l。随着日粮中木薯干叶含量的增加，白细胞显著减少（P < 0.05），从16.4×10(9)/l降至11.7×10(9)/l。试验结束时，日粮中PCV和Hb值略有增加（P > 0.05）。日粮中淋巴细胞显著减少（P < 0.05），从50.0%降至63.5%。然而，中性粒细胞在木薯干叶添加量为0%至40%时增加（P > 0.05），在添加量为60%时减少。实验开始时，葡萄糖值显著（P < 0.05）范围为40.1至56.0 mg/dl。总蛋白和白蛋白值显著（P < 0.05）分别为56.0至68.5 g/dl和30.6至38.4 g/dl。实验结束时，随着日粮中木薯干叶水平从0%增加到60%，血清肌酐显著增加（P < 0.05）。该研究表明，在西非矮山羊日粮中添加木薯干叶对其血液学和血清生化参数没有有害影响；因此，木薯干叶在反刍动物日粮中的添加量可达60%。
