The study explores synergistic interplay of and to address the current gap of suboptimal feed conversion ratio and inadequate enrichment of ω-6 fatty acids (FAs) in the breast muscle of the broiler chicken. Total 288 Ross-308 male broiler chicks were randomly distributed in a complete block design at 2 × 3 (Two different phytochemicals, i.e., , and at three different levels, i.e., 0, 0.063, and 0.125 % of the basal diet) factorial arrangement. Final live weight (FLW), average daily feed intake (ADFI), average daily gain (ADG), feed conversion ratio (FCR), carcass characteristics, cardio-pulmonary morphometry, haemato-biochemical indices, gut morphology, ileal nutrient digestibility, tibia morphometry, meat quality and FA profile were measured. Results indicated that, supplementation of leaf meal (AILM) improved 6.0 % FCR (), 35.9 % tibia calcium content () and 9.6 % of the digestibility of CP () at the expense of 14.9 % FLW (), 20.6 % ADFI (), 15.1 % ADG (), and 16.0 % right to total ventricular ratio (). Accordingly, powder (CLP) improved 2.1 % FCR () at the expense of 5.9 % FLW (), 7.6 % ADFI () and 5.3 % ADG (). The AILM substantially increased 52.4 % UFA (), 58.2 % MUFA (), 38.7 % ∑PUFA (), 41.7 % ∑ω-6 FAs () and decreased 24.3 % ∑SFA (). Similarly, the CLP increased 8.1 % ∑UFA (), 21.6 % ∑PUFA (), 22.4 % ∑ω-6 FAs () and decreased 4.3 % ∑SFA (). The AILM and CLP interacted to increase 35.3 % ∑UFA () and to decrease 21.2 % ∑SFA (). It was concluded that concomitantly improved FCR and meat quality without affecting gut morphology and haemato-biochemical indices of the broiler chicken.
本研究探讨了[具体物质1]和[具体物质2]的协同相互作用,以解决当前肉鸡胸肌饲料转化率次优和ω-6脂肪酸(FAs)富集不足的问题。总共288只罗斯308雄性肉鸡雏鸡按照2×3(两种不同的植物化学物质,即[具体物质1]和[具体物质2],分别以基础日粮的0、0.063%和0.125%三个不同水平)析因设计随机分配。测定了最终活重(FLW)、平均日采食量(ADFI)、平均日增重(ADG)、饲料转化率(FCR)、胴体特性、心肺形态测量、血液生化指标、肠道形态、回肠养分消化率、胫骨形态测量、肉质和脂肪酸谱。结果表明,添加[具体物质1]叶粉(AILM)可使FCR提高[X1]6.0%([具体数值1]),胫骨钙含量提高[X2]35.9%([具体数值2]),粗蛋白消化率提高[X3]9.6%([具体数值3]),但代价是FLW降低[X4]14.9%([具体数值4]),ADFI降低[X5]20.6%([具体数值5]),ADG降低[X6]15.1%([具体数值6]),右心室与总心室比率降低[X7]16.0%([具体数值7])。相应地,添加[具体物质2]粉(CLP)可使FCR提高[X8]2.1%([具体数值8]),但代价是FLW降低[X9]5.9%([具体数值9]),ADFI降低[X10]7.6%([具体数值10]),ADG降低[X11]5.3%([具体数值11])。AILM显著提高了不饱和脂肪酸(UFA)[X12]52.4%([具体数值12])、单不饱和脂肪酸(MUFA)[X13]58.2%([具体数值13])、总多不饱和脂肪酸(∑PUFA)[X14]38.7%([具体数值14])、总ω-6脂肪酸(∑ω-6 FAs)[X15]41.7%([具体数值15]),并使总饱和脂肪酸(∑SFA)降低[X16]24.3%([具体数值16])。同样,CLP使∑UFA提高[X17]8.1%([具体数值17]),∑PUFA提高[X18]21.6%([具体数值18]),∑ω-6 FAs提高[X19]22.4%([具体数值19]),∑SFA降低[X20]4.3%([具体数值第20])。AILM和CLP相互作用,使∑UFA提高[X21]35.3%([具体数值21]),∑SFA降低[X22]21.2%([具体数值22])。得出的结论是,[具体物质1]和[具体物质2]同时提高了肉鸡的饲料转化率和肉质,且不影响其肠道形态和血液生化指标。
