Abstract

ABSTRACT The aim was to evaluate the effect of two different rearing systems, indoor small pens (S) and big pens with outdoor access (B), on meat quality and fatty acid (FA) composition of two slow growing broiler hybrids (Rowan Ranger [RR] and Hubbard CYJA57 [H]). In addition, changes in the phospholipid FA composition, due to the possibility of more movement, were investigated. The results regarding meat quality were exclusively influenced by genotype, where RR chickens had higher breast weight, higher Warner-Bratzler shear force and higher pH than H chickens. Differences in lipid composition were found both due to hybrid and to the rearing system. The H birds were slightly leaner and had, therefore, higher proportions of phospholipids. Rearing in a big pen resulted in lower concentrations of 16:0 and higher concentrations of both total n-3 and n-6 fatty acids and of individual long chain polyunsaturated FA.

遗传背景、畜栏大小和室外通道对两个慢生长肉鸡杂种肉品质的影响

摘要本试验旨在评价室内小栏(S)和有室外通道的大栏(B)两种饲养方式对两个慢生长肉鸡杂交品种(Rowan Ranger [RR]和Hubbard CYJA57 [H])肉品质和脂肪酸组成的影响。此外，由于更多运动的可能性，磷脂FA组成的变化也进行了研究。肉品质的结果仅受基因型的影响，其中RR鸡的胸重、Warner-Bratzler剪切力和pH值高于H鸡。脂质组成的差异是由于杂交和饲养制度的不同而产生的。H型鸟类略瘦，因此磷脂比例较高。在大围栏饲养中，总n-3和n-6脂肪酸以及单个长链多不饱和脂肪酸的浓度较低，但浓度较高。
