The aim of study was to assess the growth performance, meat quality, and fatty acid composition of meat-type guinea fowl fed balanced commercial diets under two different feeding programs, similar to those for slaughter turkeys and broiler chickens, respectively. A total of 80 4-week-old meat-type guinea fowl divided into two groups (four replicates per group; 10 birds in each replicate) were raised for 14 weeks. One group received commercially available diets in a three-phased program (TM group), whereas the other group was fed commercial diets in a two-phased program (CM group). Growth-performance-related traits were recorded. At the end of rearing (14 weeks of age), eight birds from each group were slaughtered. Carcass yield and technological traits of meat (pH, color, water-holding capacity, natural and thermal loss, tenderness, fatty acid profile) were analyzed. Groups did not differ in terms of body weight as well as carcass yield and characteristics. There was no difference in meat quality and the fatty acid profile of breast and thigh meat of guinea fowl from TM and CM groups. The findings of this study suggest that both commercial diets (for broiler chickens and turkeys) can be used in meat-type guinea fowl rearing. Due to the lower price of diets fed to the CM group and the lack of significant variation in meat quality traits, its use seems to be more justified from an economic point of view.
本研究的目的是评估分别按照两种不同饲养方案，用平衡的商业饲料喂养的肉用珍珠鸡的生长性能、肉质和肉脂肪酸组成，这两种方案分别类似于用于屠宰火鸡和肉鸡的方案。总共80只4周龄的肉用珍珠鸡被分为两组（每组4个重复；每个重复10只鸡），饲养14周。一组按照三阶段方案接受市售饲料（TM组），而另一组按照两阶段方案接受商业饲料（CM组）。记录与生长性能相关的性状。在饲养结束时（14周龄），每组宰杀8只鸡。分析胴体产量和肉的加工特性（pH值、颜色、持水能力、自然损失和热损失、嫩度、脂肪酸谱）。两组在体重以及胴体产量和特性方面没有差异。TM组和CM组珍珠鸡胸肉和大腿肉的肉质和脂肪酸谱没有差异。本研究结果表明，两种商业饲料（用于肉鸡和火鸡的）均可用于肉用珍珠鸡饲养。由于CM组所喂饲料价格较低且肉质性状无显著差异，从经济角度来看，使用CM组饲料似乎更合理。
