Ensure the boar mixes with the gilts for 15-20 minutes every day. Use a boar that is at least 9 months old. To be successful with P.G. 600 you must follow the manufactures recommendations on the package. Previous researchers have demonstrated that it is possible to have normal productivity in sows injected with some hormones after they are weaned. The objective of his research is to develop a protocol so sows can be injected and then inseminated at a set time without having to determine if they are in estrus.
Preliminary results are encouraging.
Similar economic studies have not been done for sows but returns could be comparable.
