选取杜洛克公猪精液作为试验材料,比较5种稀释液时猪精液的保存效果,结果表明:用葡萄糖—柠檬酸稀释液,所保存精液的pH值、精子活率、精子畸形率等品质指标表现良好,且稀释液的成本低廉,自配简单易行,适于农村养猪户推行；基层常用的葡萄糖稀释液保存3d时的精子活率性状表现不佳,仅适合于现配现用.BL—液(美国)稀释液的保存效果也比较好,但该稀释液组分复杂,配制较难,成本也较高,可在规模养猪场中推广.%The Duroc boar semen was chosen as the tested material, and the preservation effect of 5 kinds of diluents on boar semen at normal temperature was compared. The results showed that the quality indexes (pH - value, sperm survival rate and sperm deformity rate, etc. ) of boar semen which was preserved in glucose -citric acid diluent expressed well; moreover, glucose -citric acid diluent was cheap, and was easily prepared, so it was suitable for being popularized in countryside. The sperm survival rate of boar semen preserved in frequently - used glucose diluent for 3 days expressed not so well, therefore the prepared glucose diluent should be quickly used for the boar semen preservation. The preservation effect of BL-liquid (made in America) was better, but this diluent had complex components and high cost, and was hardly prepared, so it could only be popularized in hoggery.
