摘要

The present research studied the potential of a four-generation divergent selection (Pannon maternal rabbit lines) based on the total body fat content to create two rabbit lines with different meat attributes: a Fat line to deliver greater amounts of healthy fatty acids for newborns and infants, and a Lean line intended to provide lean meat for everyday consumption. Selection was based on the fat index calculated in 10-week-old live rabbits by means of computed tomography (CT). For each generation, 60 rabbits/line were fed ad libitum with commercial pellet from weaning (5 weeks) to slaughter (11 weeks). A total of 15 rabbits/line were randomly selected for meat quality evaluations: the longissimus thoracis et lumborum muscles (LTLs), hind legs (HLs), forelegs (FLs) and abdominal wall (AW) were analyzed for their proximate composition and fatty acid (FA) profile. FA contents were also calculated. Results highlighted that it was possible to obtain leaner meat for everyday consumption in most meat portions starting from generation 4 (7.93 vs. 11.9, 5.10 vs. 5.98 and 7.26 vs. 10.9 g of lipids/100 g of meat in Lean and Fat groups for the FLs, HLs and AW, respectively). The sole exception was the LTLs, which were not affected by the divergent selection. The total PUFA amount increased in FL and AW (p < 0.05) portions of the Fat line only, attributable to a greater n-3 amount (151 vs. 216 and 73 vs. 143 mg/100 g of meat in Lean and Fat groups for the FLs and AW, respectively).

本研究研究了基于总体脂肪含量的四代发散选择（Pannon母体兔系）的潜力婴儿和一条瘦小线旨在提供瘦肉供日常消费。选择是基于计算机断层扫描（CT）在10周龄的活兔中计算出的脂肪指数。对于每一代，从断奶（5周）到屠宰（11周）的商业颗粒喂养了60只兔子/线。随机选择了总共15只兔子/线以进行肉质评估：longissimus thoracis et lumborum肌肉（LTLS），后腿（HLS），前腿（FLS）（FLS）和腹壁（AW）的邻近酸和脂肪酸成分（AW）（FA）配置文件。还计算了FA内容。结果表明，从第4代（7.93 vs. 11.9，5.10 vs. 5.98和7.26 vs. 10.9 g脂质/100 g）的瘦肉和脂肪群中，有可能在大多数肉类中获得瘦肉，以供日常食用FLS，HLS和AW）。唯一的例外是LTL，不受发散选择的影响。 PUFA总数仅增加FL和AW（p <0.05）部分脂肪线，可归因于更大的N-3量（151 vs. 216和73 vs. 143 mg/100 g的肉类和脂肪组中的肉分别为FLS和AW）。
