Abstract

Background. High cost of feed ingredients and increased demand for broiler chicken in many African countries has necessitated the search for alternative feed sources. Objective. To evaluate the effects of Hyphaene thebaica seed meal (HTSM) as substitute for maize on growth and blood parameters of broiler chickens. Methodology. Five experimental diets were formulated for the trial. Diet 1 (0% HTSM) served as the control while diets 2, 3, 4 and 5 contained 5, 10, 15 and 20% HTSM respectively replacing dietary maize in the diets of birds. A total of 225 day-old broiler chicks were randomly allotted into five treatment groups with three replicates of fifteen birds each. Each group was assigned to the five experimental diets in completely randomized design (CRD). Feed and water were supplied ad libitum for all treatment groups during the trial. Result. Differences (P<0.05) were observed in the growth parameters measured except average daily feed intake (P>0.05). Feed conversion ratio and average daily weight gain of birds fed 0, 5 and 10% HTSM diets were better (P<0.05) compared to those fed 15 and 20 % HTSM diets. Differences (P<0.05) were also observed in the blood parameters measured except the packed cell volume (29.08- 31.89%) and mean corpuscular haemoglobin (14.69-15.67pg). The white blood cell (11.45-18.14 x 109/l), red blood cell (4.71-6.99 x 1012/l), haemoglobin (6.92-10.05g/dl) and aspartate transaminase (72.95-90.16 IU/l), alanine aminotransaminase (62.84-79.50 IUu/l) and alkaline phosphatase (100.26-108.77 IU/l) increased (P<0.05) as the dietary levels of HTSM increased across the treatments. Carcass and organ weights of birds fed 0, 5 and 10% HTSM diets were better (P<0.05) than those fed 15 and 20% HTSM diets. Implication. Adequate processing of the HTSM is needed to reduce the anti-nutritional factors to a tolerable level before being used in broiler diet. Conclusion. Broiler chickens can tolerate up to 10% raw HTSM in their diets without adverse effect on growth performance.

豆瓣菜（Hyphaene thebaica）籽粒餐作为烤鸡的新型饲料：对生长反应的影响

背景。在许多非洲国家，饲料原料的高成本和肉鸡需求的增加促使人们必须寻找替代饲料来源。目的评估玉米籽粉（HTSM）作为玉米替代品对肉鸡生长和血液参数的影响。方法。试验配制了五种实验日粮。日粮 1（0% HTSM）作为对照，而日粮 2、3、4 和 5 分别含有 5%、10%、15% 和 20% 的 HTSM，以替代鸡日粮中的玉米。总共 225 只日龄肉用仔鸡被随机分配到五个处理组，每个处理组有三个重复，每个重复 15 只鸡。以完全随机设计（CRD）的方式将每组分配到五种实验日粮中。试验期间，所有处理组的饲料和水都是自由供给的。试验结果差异（P0.05）。饲喂 0%、5% 和 10% HTSM 日粮的禽类的饲料转化率和平均日增重优于饲喂 15% 和 20% HTSM 日粮的禽类（P<0.05）。除了包装细胞体积（29.08%- 31.89%）和平均血红蛋白（14.69-15.67pg）外，其他血液指标也存在差异（P<0.05）。白细胞（11.45-18.14 x 109/l）、红细胞（4.71-6.99 x 1012/l）、血红蛋白（6.92-10.05g/dl）和天门冬氨酸转氨酶（72.95-90.16 IU/l）、丙氨酸氨基转移酶（62.84-79.50 IUu/l）和碱性磷酸酶（100.26-108.77 IU/l）随着日粮中 HTSM 水平的增加而增加（P<0.05）。饲喂 0、5 和 10% HTSM 日粮的禽类的胴体和器官重量均优于饲喂 15 和 20% HTSM 日粮的禽类（P<0.05）。影响。在将 HTSM 用于肉鸡日粮之前，需要对 HTSM 进行适当加工，以将抗营养因子降至可承受的水平。结论。肉鸡可以耐受高达 10% 的生 HTSM 日粮，而不会对生长性能产生不利影响。

期刊介绍： The journal is an international peer-reviewed publication devoted to disseminate original information contributing to the understanding and development of agroecosystems in tropical and subtropical areas. The Journal recognizes the multidisciplinary nature of its scope and encourages the submission of original manuscripts from all of the disciplines involved in this area. Original contributions are welcomed in relation to the study of particular components of the agroecosystems (i.e. plant, animal, soil) as well as the resulting interactions and their relationship/impact on society and environment. The journal does not received manuscripts based solely on economic acpects o food technology.
