Effective implementation methods of chemical castrated pigs
The little boar, which is used for fattening, grows to a certain weight and castrates its testicles. A chemical castration method is introduced below. This method is very simple. When a boar less than 10 days old is injected with a mixture of sodium chloride and formaldehyde solution, its testicles will begin to swell, and the swelling will decrease after 5 days. After about half a month, the testis will atrophy significantly and lose its sexual function.
The specific method is: dissolve 10 grams of sodium chloride in 100 milliliters of distilled water, add 1 milliliter of formaldehyde solution, shake well and then filter to form a chemical castration solution, which can be put into a sterilized bottle. When injecting, first do routine disinfection in front of the vertical axis of the scrotum of the boar, and inject 2-5 milliliters of medicine into each testicle.
This method is also suitable for big boars, bulls and rams. According to the individual size of male animals, 10-20 ml solution is injected into each testicle, and the effect is also significant.
