The most complete self-check table of culture parameters
Most of the time, we are talking about management, nutrition, health care and medicine, while the performance of a pig farm depends more on indicators.
The production index directly reflects whether the production of each link of the pig farm is normal or not, and for some small farms, they are also beginning to establish their own pig farm records, but what does the recorded data look at? What do you think? A lot of people may not understand.
Pig farm owners can learn about the current situation on the farm by means of daily records and monthly statistical analysis reports, and then improve it; and the first step of improvement is to have a clear understanding of the production situation in the farm in order to improve the imperfections; below, we have collected the important production indicators of various aspects of production for your reference. I hope you can see the virtues and introspect.
