The use of insects can be a possible source of protein. This study uses sp. larvae (CLM) as a protein source in 320 one-day-old medium-growing male chicks (RedBro) during their first month of life. Chickens were randomly assigned to four dietary treatments. Each group consisted of 10 animals, and a total of 8 replicas. Control group was fed with a certified organic feed. The experimental treatments were supplemented with 5% (T2), 10% (T3), or 15% (T4) of CLM, reducing in each case the corresponding percentage of feed quantity. Productive development and meat quality were analyzed, and near infrared spectroscopy (NIRS) was used as a tool for classifying the samples. Chickens of T4 showed greater final body weight and total average daily gain, but they reduced consumption and feed conversion ratio (FCR). The chicken breast meat of T4 had lower cooking losses and higher palmitoleic acid content ( < 0.01). NIRS classified correct 92.4% of samples according to the food received. CLM is presented as a potential ingredient for the diet of medium-slow growing chickens raised in organic systems.
使用昆虫可能是一种蛋白质来源。本研究在320只1日龄中等生长速度的雄性雏鸡(红宝肉鸡)出生后的第一个月,将黄粉虫幼虫(CLM)用作蛋白质来源。将鸡随机分为四种日粮处理组。每组由10只动物组成,共8个重复。对照组饲喂认证有机饲料。实验处理组分别添加5%(T2)、10%(T3)或15%(T4)的CLM,并相应减少饲料量的百分比。分析了生产性能发育和肉质,并使用近红外光谱(NIRS)作为样本分类工具。T4组的鸡最终体重和总平均日增重更高,但它们的采食量和饲料转化率(FCR)降低。T4组鸡胸肉的烹饪损失较低,棕榈油酸含量较高(P<0.01)。NIRS根据所接受的食物正确分类了92.4%的样本。CLM被认为是有机系统中饲养的中等生长速度鸡日粮的潜在成分。
