Abstract

The poultry industry needs alternative feeds with no adverse effects on animal performance and egg quality. Insects represent effective animal feeds. However, Ptecticus tenebrifer (PT) has rarely been studied as an effective feed in terms of fatty acid contents. Therefore, we investigated the effect of dietary PT powder on the fatty acid profiles of egg yolks in laying hens. A total of 180 Hy-Line brown hens were divided equally into three groups (n = 60), with three replicates: the control group and two groups fed 2% and 4% PT powder, respectively. After 2 weeks, minor effects (P < 0.05) on oleic acid, dihomo-gamma-linolenic acid, and total monounsaturated fatty acids were observed among the groups. After 4 weeks, docosahexaenoic acid, docosapentaenoic acid, myristic acid, oleic acid, and total polyunsaturated fatty acids were slightly altered in the treatment groups (P < 0.05). For other fatty acids, the 2% and 4% PT groups had fatty acid concentrations similar to those of the controls. No differences in total n-6 and total n-3 were observed among the groups. In conclusion, using 2% and 4% PT powders did not notably change the fatty acid profiles of egg yolks and could replace some layer-hen feed without negative effects.

饲粮中添加粉对蛋鸡蛋黄脂肪酸谱的影响
家禽业需要对动物生产性能和蛋质量没有不利影响的替代饲料。昆虫是有效的动物饲料。然而,从脂肪酸含量的角度来看,粉麻(PT)作为一种有效饲料的研究很少。因此,本试验旨在研究饲粮中添加PT粉对蛋鸡蛋黄脂肪酸谱的影响。试验选用180只海兰褐鸡,随机分为3组(n = 60),设3个重复,对照组和2组分别饲喂2%和4% PT粉。2周后,轻微影响(P <各组间油酸、二同γ -亚麻酸和总单不饱和脂肪酸的差异均为0.05)。4周后,各处理组二十二碳六烯酸、二十二碳五烯酸、肉豆蔻酸、油酸和总多不饱和脂肪酸略有变化(P <0.05)。对于其他脂肪酸,2%和4% PT组的脂肪酸浓度与对照组相似。总n-6和总n-3在各组间无显著差异。综上所述,添加2%和4% PT粉对蛋鸡蛋黄脂肪酸谱变化不显著,可替代部分蛋鸡饲料,且无负面影响。
