A Detailed Guide to Pig Feed Formulas and Scientific Preparation Methods
Pig feed is a granular substance that supplements nutrition for pigs; it can enhance pigs' disease resistance and promote their growth. So what exactly goes into a pig feed formula?
1. Pig Feed Formulas
Feed formula for growing-finishing pigs weighing 60-120 jin

2. Building Pens for Free-Range Pigs
The requirements for free-range pig pens differ from those for home-raised pig pens. Free-range pig pens are generally built in forest areas, where the temperature difference between day and night is large and there is more rain, so keeping warm must be taken into account when building the pen. Choose a spot in a mountain gully that is sheltered from the wind and faces the sun, on higher ground, and where drainage is easy. The pen area should not be too large; generally it is enough to put one litter of piglets in one pen.
The above is the relevant knowledge about pig feed formulas; we hope it is helpful to everyone.
