The study was conducted with the view to determine the impact of replacing fishmeal with black soldier fly larval meal (BSFLM) on growing guinea fowls. BSFLM replaced fishmeal (3% in the control diet) in the ratios of 0, 20, 40, 60, 80, and 100% to produce six dietary treatments, which were iso-caloric and iso-nitrogenous. Two hundred and forty-eight-week old guinea fowls with mean live weight of 273.2 ± 10.9 g were tagged, weighted, and randomly assigned to 24 (6 × 4) floor pens; each pen was treated as a replicate. Feed and water were provided ad libitum during the entire period, which lasted 10 weeks. Feed consumption differed among the treatment groups (P = 0.0072) with the 100% fishmeal diets recording the lowest. Daily gain was significantly (P = 0.009) higher for birds fed high BSFLM diets compared to the control (100% fishmeal diet). The inclusion of BSFLM in the diets elicited positive linear effect on weight gains of the guinea fowls (R = 0.91) with increasing concentration resulting in higher live weight gains. The feed conversion ratio (FCR) also differed between treatments (P < 0.05) but similar for the 100% fishmeal (control) and 100% BSFLM diets. Organ and haematopoitic integrity were equally assured regardless of levels of the protein sources fed to the birds. Generally, meats from birds fed 60 to 100% BSFLM and from hens were more acceptable. A study to evaluate the economics of utilising BSFLM in guinea fowl production is recommended.
本研究旨在确定用黑水虻幼虫粉（BSFLM）替代鱼粉对生长中的珍珠鸡的影响。BSFLM以0、20、40、60、80和100%的比例替代鱼粉（对照日粮中为3%），以产生六种等热量和等氮的日粮处理。24只8周龄珍珠鸡，平均体重273.2±10.9克，进行标记、称重，并随机分配到24个（6×4）地面围栏中；每个围栏作为一个重复。在为期10周的整个期间，自由提供饲料和水。各处理组之间的采食量存在差异（P = 0.0072），100%鱼粉日粮的采食量最低。与对照组（100%鱼粉日粮）相比，饲喂高BSFLM日粮的鸡的日增重显著更高（P = 0.009）。日粮中添加BSFLM对珍珠鸡的体重增加产生正线性影响（R = 0.91），随着浓度增加，活体重增加更高。饲料转化率（FCR）在各处理之间也存在差异（P < 0.05），但100%鱼粉（对照）和100% BSFLM日粮相似。无论饲喂鸡的蛋白质来源水平如何，器官和造血完整性均得到保证。一般来说，饲喂60%至100% BSFLM的鸡和母鸡的肉更受欢迎。建议开展一项评估在珍珠鸡生产中使用BSFLM的经济性的研究。
