【摘要】 本试验为考察新研制的4925/4926母猪系列预混合饲料的饲养效果,在母猪胎次、体况和饲养管理条件相似、基础饲料相同条件下,分别与金牧3863/3864、康地5743/5744两种母猪系列预混料进行饲养试验.入试头数分别为23头、35头.结果表明:①4925/4926组较3863/3864组,窝产活仔数、初生窝重、断奶窝重分别提高0.5头/窝、0.9kg/窝、4.25kg/窝;哺乳期母猪头平少失重3.88kg.②主要繁殖性能指标均达到或超过康地5743/5744系列预混料的饲养效果,每头母猪增加经济效益50~80元.更多还原

【Abstract】 The expriment was conducted to determine the feeding effectiveness of JINMU brand 4925/4926 premix newly made for sow. On the condition that sow delivery order, body condition, basal diet and feeding mode are same or similar, 4925/4926 premix was test-ed comparing with JINMU brand 3863/3864 and CONTI brand 5743/5744 premix respective-ly. The result showes as follows: 1. Litter live number at birth, litter live weight at birth and litter weaning weight of the 4925/4926 premix group increased by 0. 5,0. 9kg, 4. 25kg more than those of 3863/3864 premix group respectively, while sow weight loss at muring period lessened 3. 88kg comparing with that of 3863/3864 group. 2. Most of the reproduc-tive performances of sow in the 4925/4926 premix group are equal or superior to those in the 5743/5744 premix group. One head of sow of the 4925/4926 premix group can gain RMB 50-80 more than that of the 5743/5744 premix group on average.更多还原
