Two trials were conducted to assess the acceptance, safety and digestibility of diets containing various inclusion levels of partially defatted black soldier fly (Hermetia illucens) larvae (BSFL) meal and BSFL oil by dogs. In trial 1, 5 extruded diets were evaluated for acceptance in adult Beagle dogs (n = 20; 10 male, 10 female) during a 48-hr period. Diets contained graded levels of BSFL meal (5.0%, 10.0%, and 20.0%), or graded levels of BSFL oil (2.5% and 5.0%), and all diets were well accepted. Thus, a digestibility trial (trial 2) was run with 56 adult dogs (16 male, 40 female) allocated into 7 dietary treatments; dogs were offered an extruded control diet containing no BSFL meal or oil, or extruded diets where BSFL meal partially replaced poultry by-product meal and corn meal at dietary levels of 5%, 10%, or 20% inclusion, or diets with BSFL oil partially replacing poultry fat at a 1:1 ratio at levels of 1%, 2.5%, or 5% inclusion. The treatment diets were fed for 28 d, during which time dogs were monitored for health (via physical examinations, clinical observations, and blood chemistry and hematology) and ingredient evaluation (via body weight, feed consumption, stool observation, and fecal nutrient apparent total tract digestibility). There were no significant differences in body weight or food consumption between treatment groups (P > 0.05) and daily observations indicated that the general health of the animals was maintained throughout the study. Stool quality was maintained at 3.2 to 3.4 (on a 5-point scale with a score of 1 being watery diarrhea and a score of 5 being hard, dry, and crumbly) per treatment group over the fecal observation period (days 22 to 27), indicating a well formed, sticky stool. All group mean hematology and blood chemistry parameters remained within normal limits for dogs. Apparent total tract digestibility of dry matter, protein, fat, and calories was not affected by treatment (P > 0.05). In general, amino acid digestibility was not impacted by treatment although some minor changes were observed. Apparent total tract digestibility was high for all nutrients examined. Overall, it was concluded that BSFL meal and BSFL oil are well tolerated by dogs and their consumption results in no impact to physiology that would be concerning. Based on these data, BSFL meal and oil did not affect general health and could be included safely in dog diets.
两项试验评估了含有不同水平部分脱脂黑水虻（Hermetia illucens）幼虫粉（BSFL）和 BSFL 油的饮食对犬的接受度、安全性和消化率。在试验 1 中，5 种膨化饮食在成年比格犬（n = 20；10 只雄性，10 只雌性）中进行了 48 小时的接受度评估。饮食中含有不同水平的 BSFL 粉（5.0%、10.0%和 20.0%）或不同水平的 BSFL 油（2.5%和 5.0%），所有饮食均被很好地接受。因此，用 56 只成年犬（16 只雄性，40 只雌性）进行了消化率试验（试验 2），并将它们分配到 7 种饮食处理中；犬只提供含有无 BSFL 粉或油的膨化对照饮食，或膨化饮食中 BSFL 粉部分替代禽副产品粉和玉米粉，替代水平为 5%、10%或 20%，或 BSFL 油以 1:1 的比例部分替代禽脂，替代水平为 1%、2.5%或 5%。治疗饮食喂养 28 天，在此期间监测犬的健康状况（通过体检、临床观察以及血液化学和血液学）和成分评估（通过体重、食物摄入量、粪便观察和粪便养分表观全肠道消化率）。各组之间的体重或食物摄入量没有差异（P > 0.05），每日观察表明，动物的整体健康状况在整个研究过程中得到维持。每个治疗组的粪便观察期（第 22 至 27 天）粪便质量维持在 3.2 至 3.4（五分制，1 分为水样腹泻，5 分为坚硬、干燥和易碎），表明粪便成型、粘稠。所有组的平均血液学和血液化学参数均在犬的正常范围内。干物质、蛋白质、脂肪和热量的表观全肠道消化率不受处理的影响（P > 0.05）。一般来说，氨基酸消化率不受处理的影响，尽管观察到一些微小的变化。所有检查的营养素的表观全肠道消化率都很高。总的来说，黑水虻幼虫粉和黑水虻油被犬很好地耐受，它们的消耗不会对生理造成任何影响。基于这些数据，黑水虻幼虫粉和油不会影响犬的一般健康状况，可以安全地添加到犬的饮食中。
