Abstract

This study was conducted to investigate the effect of dietary inclusion of biochar and clay as feed additives on the growth performance and organ weight of broilers in a 56-day feeding trial. A total of ninety-six day-old broilers (Ross 308) were fed diets containing biochar and clay. Treatments 1, 2, 3 and 4 were composed of T1(control), T2(5% biochar), T3 (5% clay) and T4 (2.5% biochar + 2.5% clay) in a completely randomized design with three replicates, each consisting of eight birds. The growth parameters were measured during the feeding trial and organ weight parameters were measured at the end of the experiment. The data collected were subjected to one-way analysis of variance to determine the significant differences among the dietary treatments. The results showed that treatments were significantly ( p < 0.05) different in final weight, total weight gain, average daily weight gain, total feed intake, average daily feed intake, feed cost per kg weight gain and kidney weight. Treatment 4 had the highest final weight value of 1.4067kg, highest total weight gain of 1.3597kg, highest average daily weight gain of 0.0242kg, highest total feed intake of 5.1097kg, highest average daily feed intake of 0.0910kg and highest feed cost of N3227.21. However, there were no significant ( p > 0.05) differences in initial weight, feed conversion ratio, feed cost per kg weight gain, heart, liver, pancreas, gizzard, spleen and lung weights. The results imply that inclusion of biochar and clay at 2.5% each in broiler diet can potentially increase growth performance

生物炭和粘土对肉鸡生长性能和器官重量的影响

本研究旨在调查在为期 56 天的饲养试验中，日粮中添加生物炭和粘土作为饲料添加剂对肉鸡生长性能和器官重量的影响。共有 96 只日龄肉鸡（Ross 308）饲喂了含有生物炭和粘土的日粮。处理 1、2、3 和 4 分别由 T1（对照组）、T2（5% 生物炭）、T3（5% 粘土）和 T4（2.5% 生物炭 + 2.5% 粘土）组成，采用完全随机设计，三个重复，每个重复八只鸡。在饲喂试验期间测量生长参数，在试验结束时测量器官重量参数。对收集的数据进行单因素方差分析，以确定日粮处理之间的显著差异。结果表明，各处理在最终体重、总增重、平均日增重、总采食量、平均日采食量、每千克增重的饲料成本和肾脏重量方面存在显著差异（P < 0.05）。处理 4 的最终体重值最高，为 1.4067 千克；总增重最高，为 1.3597 千克；平均日增重最高，为 0.0242 千克；总采食量最高，为 5.1097 千克；平均日采食量最高，为 0.0910 千克；饲料成本最高，为 3227.21 纽元。然而，初始体重、饲料转化率、每千克增重的饲料成本、心脏、肝脏、胰腺、胗、脾脏和肺的重量均无明显差异（P > 0.05）。结果表明，在肉鸡日粮中添加生物炭和粘土各 2.5%，有可能提高肉鸡的生长性能。
