This study evaluated the effect of feeding cassava leaf meal-based diets on feeding behavioural patterns, growth performance parameters and nutritional status of chickens. A total of 200 Cobb-500 female chickens (initial weight 0.53 ± 0.098 kg) were used in the experiment. The chickens were subjected to treatment diets with cassava leaf meal (CLM) included in diets at 0, 100, 200 and 300 g/kg. Number of visits to the feeder/drinker, duration of each visit on the feeder/drinker, average daily feed intake (ADFI), average daily gain (ADG) and feed efficiency (gain:feed ratio), total protein (TP), albumin, globulin and creatine kinase (CK) were the response variables that were measured of interest. Effects of inclusion level of CLM in diets of chickens on number of visits to the feeder and drinker was significant (P < 0.05). Duration of each visit on the feeder increased (P < 0.05) with inclusion level of CLM in diets of chickens. Conversely, time spent by chickens on the drinker decreased with inclusion level of CLM in diets (P < 0.05). Average daily gain and G:F decreased linearly (P < 0.05) with inclusion level of CLM in diets of chickens. Albumin, globulin and total protein in blood of chickens increased linearly (P < 0.05) with inclusion level of CLM in diets of chickens. From the study, it can be concluded that acceptability of diets with inclusion of CLM during the growing-finishing phase of the chickens was not affected. However, weight gain was compromised at higher inclusion levels of CLM in diets of chickens.
本研究评估了以木薯叶粉为基础的日粮对鸡的采食行为模式、生长性能参数和营养状况的影响。实验共使用了200只科宝500品系的雌性鸡（初始体重0.53±0.098千克）。这些鸡被饲喂含木薯叶粉（CLM）的日粮，日粮中CLM的添加量分别为0、100、200和300克/千克。到饲槽/饮水器的访问次数、每次在饲槽/饮水器上的停留时间、平均日采食量（ADFI）、平均日增重（ADG）和饲料效率（增重：饲料比）、总蛋白（TP）、白蛋白、球蛋白和肌酸激酶（CK）是所测量的感兴趣的响应变量。日粮中CLM添加水平对鸡到饲槽和饮水器的访问次数有显著影响（P<0.05）。随着日粮中CLM添加水平的增加，每次在饲槽上的停留时间增加（P<0.05）。相反，随着日粮中CLM添加水平的增加，鸡在饮水器上花费的时间减少（P<0.05）。随着日粮中CLM添加水平的增加，平均日增重和料重比呈线性下降（P<0.05）。随着日粮中CLM添加水平的增加，鸡血液中的白蛋白、球蛋白和总蛋白呈线性增加（P<0.05）。从该研究可以得出结论，在鸡的生长育肥阶段，日粮中添加CLM的可接受性不受影响。然而，日粮中CLM添加水平较高时，体重增加会受到影响。
