The problem of sow lameness should be treated correctly in large-scale pig farms.

To evaluate the situation of claudication in pig farms, we should first carefully evaluate the injury of hooves; secondly, we should evaluate the relevant indicators of production performance, including pregnancy rate, delivery rate, percentage of euthanasia sows, and so on.

In clinical practice, we found that the improvement of claudication was positively correlated with the improvement of reproductive index. Therefore, it is best to start treatment in the growth and development period of sows, so as to reduce the occurrence of osteochondrosis at the joints. After treatment with chelates in the backup sows, it was found that the elimination rate of the third stage of delivery decreased significantly. Together, it decreased from 42.8% to 23.3%.

After the use of organic mineral chelates in pig farms, there will be a significant reduction in lameness and hoof damage, and the quality of the cuticle will be improved from dark brown to ivory. We can never evaluate the degree of claudication only by the "naked eye". At the same time, we must also analyze other indicators to assess whether the situation has improved. This is why data on production performance is also crucial.
