Yellow-head catfish meat semen preserving fluid and preparation method thereof

Abstract

The invention discloses yellow-head catfish meat semen preserving fluid and a preparation method thereof. The yellow-head catfish meat semen preserving fluid is characterized by being prepared through the following steps: mixing 0.5-1.5% of trisodium citrate, 1.5-3.5% of glucose, 0.1-0.3% of sodium bicarbonate, 0.02-0.04% of potassium chloride and deionized water in percentage by mass volume, putting the mixture into a magnetic stirrer, stirring for 3-15 minutes, and determining the volume after sufficiently dissolving. Tests show that if yellow-head catfish meat semen is preserved in the preserving fluid for 8 hours at normal temperature, 100% of sperms have the activity after being activated, and the fertility rate is 98% when the sperms are used for fertilization; if the semen is preserved for 14 days at the refrigeration condition of 4 DEG C, 100% of the sperms have the activity, and the fertility rate is 95% when the sperms are used for fertilization.
