The Most Complete Self-Check Table of Breeding Parameters, a Must-Have for Quick Reference by Farmers
Many times we talk about management, talk about nutrition, talk about health care, talk about medication, yet whether a pig farm is run well is judged more by its indicators.
Production indicators directly reflect whether the production at each stage of the pig farm is normal or not. Some small farms have also begun to keep their own farm records, but what should be looked at in the recorded data? How should it be read? Many people may still not understand.
Pig farm owners can use the records accumulated daily and the monthly statistical analysis reports to understand the current situation on the farm and then make improvements; and the first step of improvement is to clearly know the production situation on the farm, so as to make improvements to the areas that are not perfect; below we have collected the important production indicators of each stage of production for your reference, and we hope everyone can emulate those who excel and reflect inwardly upon those who do not.

Comparing with the table above, we hope to help you identify the several aspects you most need to improve, and to use this as a basis for setting future work targets, and to let all employees know the direction of production development and how to achieve the targets currently set.
