This work examined the results of different dietary protein levels on indigenous Nigerian guinea fowl growth performance and carcass yield.
One hundred and eight unsexed indigenous keets were randomly assigned to three treatments with experimental diets containing 22%, 24%, and 26% crude protein (CP) in a completely randomized design, with 3 replicates with 12 keets in each replicate. The parameters were measured, including proximate composition, feed intake, growth rate, feed conversion ratio (FCR), and carcass yield.
The birds fed diets containing 24% CP gained the most body weight at 619.83 gm and had the highest FCR of 3.45. The presence of CP had an impact that was significant ( < 0.05) on most carcass traits and prime cuts but not on gastrointestinal tract weight, head weight, dress percentage, or organ yield.
The study concluded that the dietary CP level of 24% was optimal for body weight gain and carcass yield.
本研究探讨了不同膳食蛋白质水平对尼日利亚本土珍珠鸡生长性能和胴体产量的影响。
108只未区分性别的本土雏鸡被随机分配到三种处理组，分别饲喂粗蛋白（CP）含量为22%、24%和26%的实验日粮，采用完全随机设计，每组重复3次，每次重复12只雏鸡。测定的参数包括近似成分、采食量、生长速率、饲料转化率（FCR）和胴体产量。
饲喂含24%CP日粮的鸡体重增加最多，达619.83克，饲料转化率最高，为3.45。CP的存在对大多数胴体性状和主要切块有显著影响（<0.05），但对胃肠道重量、头部重量、屠宰率或器官产量没有影响。
该研究得出结论，日粮CP水平为24%时，对体重增加和胴体产量最为适宜。
