How to treat rectal prolapse in pigs? Introduction to commonly used therapies
Rectal prolapse in pigs falls into two situations: the first is that the sick pig can retract the prolapsed tissue on its own when standing, but it protrudes again when defecating; the second is that the sick pig cannot retract it on its own when standing. For the latter, surgical treatment is often adopted, with a cure rate of up to 100%. Now, for the first situation, a simple therapy worth promoting is introduced.
