北方地区肉用仔鹅的生产试验研究

The Research of Gosling Production in Northen China

摘要:

随机选择刚出生的本地鹅雏和杂交鹅雏各130只,采取放牧加补饲的方法育肥至63日龄。结果本地鹅平均体重328750g,胴体重285410g,半净膛率8018%,全净膛率7376%,料肉比为331∶1;杂交鹅平均体重348269g,胴体重296192g,半净膛率7863%,全净膛率7264%,料肉比为304∶1。说明该方法育肥效果理想,且杂交鹅优于本地鹅。结合经济效益分析证明,在北方地区利用本地品种资源,适当进行杂交,抓住其生长发育的有利时机,采取放牧加补饲的方法发展肉用仔鹅生产是切实可行的。

Abstract:

The 130 Jilin goslings and the 130 crossbred goslings were tested after 63 days of fatting with grazing and feeding . The result shows that both gosling can be fatten in 63 days, and the crossbreeds’liveweight (3482.69g) is higher than the Jilin’s (3287.50g), so are the carcass weight (2961.92 g to 2854.10g), semi-dressing percentage (80.18% to 78.63%), dressing percentage (73.76 % to 72.64%), but the feed/gain is contrary (3.04:1 to 3.31:1). The economic benefit analysis shows that the crossbred gosling feeding is practigal.
