Detailed Explanation of Effective Methods for Chemical Castration of Pigs

For young male pigs raised for fattening, once they reach a certain weight, their testicles must be surgically removed. Below is an introduction to a chemical castration method. This method is very simple: inject a mixture of sodium chloride and formaldehyde solution into male piglets within 10 days of age, and their testicles will begin to swell, then subside on their own after 5 days. After about half a month, the testicles shrink significantly and lose sexual function.

The specific method is: dissolve 10 grams of sodium chloride in 100 milliliters of distilled water, then add 1 milliliter of formaldehyde solution, shake well and filter. This makes the chemical castration solution, which can be stored in a sterilized bottle for later use. During injection, first carry out routine disinfection in front of the longitudinal axis of the piglet's scrotum, then inject 2-5 milliliters of the solution into each testicle.

This method is also suitable for large male pigs, bulls and rams. Depending on the individual size of the male animal, inject 10-20 milliliters of the solution into each testicle, and the effect is also quite significant.
