【摘要】 狮头鹅是我国唯一的大型鹅种,但其繁殖力低下,产蛋季节性明显。SB21杂交鹅是汕头市白沙禽畜原种研究所引进四川白鹅与狮头鹅杂交,经多年精心选育而成。SB21杂交鹅保持了狮头鹅优良的产肉性能,克服了狮头鹅繁殖力低下的弱点。通过狮头鹅与SB21杂交鹅的反季节生产对比试验,发现每只SB21杂交鹅比每只狮头鹅多产17.24枚蛋和16.01枚受精蛋,经t检验差异极显著(P<0.01)。更多还原

【Abstract】 The Shitou goose is the only goose species with large-body in China,but its reproductive capacity is low and its egg laying has seasonal aspects obviously.The SB21 cross-breeding goose is a cross breeding species between Shichuan white goose and Shitou goose.The SB21 keeps good aspects of meat production and overcome the weakness of low reproductive capacity of Shitou goose.After the off-season production comparation of Shitou goose and SB21 goose,we found that each SB21 goose could lay 17.21 eggs and 16.01 fertilized eggs more than Shitou goose(P<0.01).更多还原
