吉林省本地鹅和杂交鹅的产肉性能及胴体分割的研究

Study on Meat-productive Performance and Carcass Segmentation of Home and Cross Geese

摘要:

随机选择刚出生的本地鹅雏和杂交鹅雏各130只, 采用放牧加补饲的方式育肥至63日龄, 进行屠宰测定。结果本地鹅平均活重3287.50g, 胴体重2854.10g, 半净膛率80.18%,全净膛率73.76%,头重129.3g, 颈重243.2g, 翅重157.6g;杂交鹅平均活重3482.69g, 胴体重2961.92g, 半净膛率78.63%,全净膛率72.6%,头重136.2g, 颈重257.5g, 翅重166.2g。表明该方式育肥效果显著, 且杂交鹅优于本地鹅。通过与全放牧方式育肥的同龄本地鹅对比, 说明品种、性别、育肥方式对育肥效果均有影响。

Abstract:

The goslings of 130 Jilin geese and their 130 crossbreeds were slaughtered and divided after 63 days of fatting with grazing and feeding. The result shows that the liveweight of crossbreed is higher than that of Jilin geese (3 482.69 g to 3 287.50 g), so is the carcass weight (2 961.92 g to 2 854.10 g), head weight (136.2 g to 129.3 g), cervix weight (257.5 g to 243.2 g), wing weight (166.2 g to 157.6 g). But both the semi-dressing percentage (78.63 g to 80.18 g) and the dressing percentage (72.64 g to 73.76 g) are low.
