A 6-weeks study was designed to determine the effect of dietary interaction of sodium bentonite and litter treated with aluminum sulfate on growth performance, litter quality and serum biochemical indices of Nigerian Noiler birds. A total of 180 mixed sex (2 weeks old) Nigerian Noiler birds were allotted to six treatment groups in a 3 × 2 factorial arrangements in a completely randomized design with 5 replicates of 6 birds each and were fed ad libitum. Sodium bentonite was used at 3 levels (0, 15 and 30 g/kg), while aluminum sulfate was used at 2 levels (0 and 400 g/3 kg litter). Treatments include: T1 = 0 g NaB /kg + 0 g alum/3 kg litter, T2 = 15 g NaB /kg + 0 g alum /3 kg litter, T3 = 30 g NaB /kg + 0 g alum/3 kg litter, T4 = 0 g NaB /kg + 400 g alum /3 kg litter, T5 = 15 g NaB /kg + 400 g alum/3 kg litter and T6 = 30 g NaB /kg diet + 400 g alum/3 kg litter. Results showed that the interaction of dietary sodium bentonite and litter treated with aluminum sulfate caused significant effect (p < 0.05) on the values of feed intake, ADFI, WG, ADWG, feed cost per kg gain, litter NH, moisture, pH, TVC, salmonella, serum cholesterol, LDL and triglyceride, ALT, AST and bilirubin. Birds fed sodium bentonite and on litter treated with aluminum sulfate performed better (p < 0.05) than the control group. Litter moisture and pH were lower (p < 0.05) in treated litter than the control. Litter ammonia gas of 28.66 observed in control litter was higher (p < 0.05) than the 18.50, 17.00, 16.66, 12.50 and 13.65 recorded in T2-T6. TVC value of 0.83 × 10 and salmonella value of 1.53 × 10 obtained in control litter were the highest (p < 0.05) across the treatments. Serum cholesterol, LDL and triglyceride were higher (p < 0.05) in treated groups, while the serum liver enzymes and bilirubin values were also lower (p < 0.05) in treated groups compared to control. In summary, the study observed that dietary sodium bentonite and litter treated with aluminum sulfate improved the litter quality without any damaging impact on the growth performance and serum biochemical parameters of the birds. It was concluded that 15 g NaB /kg + 400 g alum/3 kg litter can be applied by the poultry farmers to enhance the performance, litter quality and health of avian species.
一项为期6周的研究旨在确定膨润土与用硫酸铝处理的垫料之间的饮食相互作用对尼日利亚诺伊勒鸡生长性能、垫料质量和血清生化指标的影响。总共180只混合性别（2周龄）的尼日利亚诺伊勒鸡被分配到6个处理组，采用3×2析因设计，完全随机排列，每组6只鸡，共5个重复，自由采食。膨润土的添加量为3个水平（0、15和30克/千克），硫酸铝的添加量为2个水平（0和400克/3千克垫料）。处理包括：T1 = 0克膨润土/千克 + 0克明矾/3千克垫料，T2 = 15克膨润土/千克 + 0克明矾/3千克垫料，T3 = 30克膨润土/千克 + 0克明矾/3千克垫料，T4 = 0克膨润土/千克 + 400克明矾/3千克垫料，T5 = 15克膨润土/千克 + 400克明矾/3千克垫料，T6 = 30克膨润土/千克日粮 + 400克明矾/3千克垫料。结果表明，日粮膨润土与用硫酸铝处理的垫料之间的相互作用对采食量、平均日采食量、体重增加、平均日增重、每千克增重的饲料成本、垫料氨含量、湿度、pH值、总活菌数、沙门氏菌、血清胆固醇、低密度脂蛋白和甘油三酯、谷丙转氨酶、谷草转氨酶和胆红素的值有显著影响（p < 0.05）。饲喂膨润土并使用硫酸铝处理垫料的鸡比对照组表现更好（p < 0.05）。处理后的垫料中垫料湿度和pH值低于对照组（p < 0.05）。对照组垫料中观察到的氨气含量为28.66，高于T2 - T6组记录的18.50、17.00、16.66、12.50和13.65（p < 0.05）。对照组垫料中获得的总活菌数为0.83×10，沙门氏菌值为1.53×10，是所有处理中最高的（p < 0.05）。处理组的血清胆固醇、低密度脂蛋白和甘油三酯较高（p < 0.05），而与对照组相比，处理组的血清肝酶和胆红素值也较低（p < 0.05）。总之，该研究观察到日粮膨润土和用硫酸铝处理的垫料改善了垫料质量，且对鸡的生长性能和血清生化参数没有任何不良影响。得出的结论是，家禽养殖户可以使用15克膨润土/千克 + 400克明矾/3千克垫料来提高禽类的生产性能、垫料质量和健康水平。
