The aim of the study was to determine the effect of feeding Zatorska variety geese hybrid rye, oats, or a mixture of both grains (1:1) on slaughter value and meat quality. At 14 weeks old, the birds were separated into three feeding groups ( = 12) and were fed between 15 and 17 weeks of age with hybrid rye, oats, or a mixture of these two grains. The research proved the effect of gender and feeding on some slaughter value traits and meat quality of the goslings' breast meat. It was found that the ganders had a 10% to 15% higher body and carcass weight than the females. No significant differences were observed between the genders within the majority of the physical and chemical characteristics as well as the sensory traits. The feeding type did not have a significant effect on the goslings' body weight and carcass element share. The birds fed hybrid rye had a 2 percentage points lower slaughter yield than those birds fed oats which was combined with a lower share of subcutaneous fat (measured as the weight of the tissue coming from dissection) in birds fed hybrid rye. The meat of the birds fed hybrid rye had some better physical, chemical characteristics and, in the female goslings, also better sensory quality. The results indicated that hybrid rye may be used in feeding goslings at the end of the growing period, because it did not cause any negative effects on the pre-slaughter body weight and had a positive effect on some meat quality traits, such as better sensory estimation results, higher protein content, and lower drip losses.
本研究的目的是确定用扎托尔斯卡品种的鹅饲喂杂交黑麦、燕麦或两种谷物的混合物（1:1）对屠宰价值和肉品质的影响。在14周龄时，将鹅分为三个饲喂组（每组n = 12），并在15至17周龄期间用杂交黑麦、燕麦或这两种谷物的混合物进行饲喂。研究证明了性别和饲喂方式对雏鹅胸肉的一些屠宰价值性状和肉品质有影响。结果发现，公鹅的体重和胴体重比母鹅高10%至15%。在大多数物理和化学特性以及感官性状方面，未观察到性别之间的显著差异。饲喂类型对雏鹅的体重和胴体组成部分的比例没有显著影响。饲喂杂交黑麦的鹅的屠宰率比饲喂燕麦的鹅低2个百分点，同时，饲喂杂交黑麦的鹅皮下脂肪的比例（以解剖得到的组织重量衡量）也较低。饲喂杂交黑麦的鹅的肉具有一些更好的物理和化学特性，并且在母雏鹅中，感官品质也更好。结果表明，杂交黑麦可用于生长期末期雏鹅的饲喂，因为它对宰前体重没有任何负面影响，并且对一些肉品质性状有积极影响，如更好的感官评价结果、更高的蛋白质含量和更低的滴水损失。
