The aim of this study was to compare carcass traits, meat quality and sensory attributes in two different genotypes of geese according to age and sex.
The experiment was carried out on 160 birds of two genotypes of geese: the Czech Goose (CG) breed and a Eskildsen Schwer (ES) hybrid. One-d-old goslings were divided into four groups according to genotype and sex. Two dates for slaughtering (at 8 and 16 wk of age of goslings) were undertaken.
The slaughter weight, cold carcass weight and dressing percentage were affected by all the studied factors, and significant interactions between age, genotype and sex were detected in the slaughter weight (p<0.001) and cold carcass weight (p = 0.004). The pH was not affected by any of studied factors, whereas in terms of meat colour parameters there were observed significant effects of age on L* and b* value and a significant effect of sex on a* value. The meat fat content was higher (p = 0.002) in ES. Higher score for overall acceptance of goose meat was recorded for ES at both ages compared to CG.
ES had higher dressing percentage and better sensory attributes, whereas CG exceled in the favourable nutritional value of the meat.
本研究旨在根据年龄和性别比较两种不同基因型鹅的胴体性状、肉质和感官特性。
对160只两种基因型的鹅进行了实验，即捷克鹅（CG）品种和埃斯基尔森施韦尔（ES）杂交种。1日龄雏鹅根据基因型和性别分为四组。进行了两个屠宰日期（雏鹅8周龄和16周龄时）的屠宰。
屠宰体重、冷胴体重和屠宰率受所有研究因素的影响，在屠宰体重（p<0.001）和冷胴体重（p = 0.004）方面检测到年龄、基因型和性别之间存在显著交互作用。pH值不受任何研究因素的影响，而在肉色参数方面，观察到年龄对L和b值有显著影响，性别对a*值有显著影响。ES的肉脂肪含量更高（p = 0.002）。与CG相比，ES在两个年龄时的鹅肉总体接受度得分更高。
ES的屠宰率更高，感官特性更好，而CG在肉的营养价值方面表现出色。
