Non-genetically modified vaccines are allowed and encouraged in organic pig production.
Injecting newborn pigs with supplemental iron to prevent anemia is allowed.
The use of feed additives such as organic acids, probiotics, and directly fed microbials to encourage animal
health is not prohibited, but not all health-promoting feed additives are approved for use in organic production.
Artificial insemination is allowed, but administrating hormones to synchronize estrus or stimulate growth is
prohibited in organic production.
Approved parasiticides also can be used when preventive practices have proven ineffective. Use of parasiticides
is restricted to breeding stock, and they must be administered prior to the last third of gestation.
Treating lactating sows or market animals with parasiticides is required if medically necessary, but the sow,
her nursing piglets, and the market animals would then lose their organic status.
Physical alteration of organic livestock to promote their welfare is allowed but should be performed in a
manner that minimizes pain and stress.
Organic livestock must be identified, and the use of ear notches, ear tags, and tattoos are all currently
approved methods for individually marking breeding stock and potential replacements.
