1. Choose a good hybrid pig breeding:
Choose a high-quality single breed of hybrid pig breeding, refuse a variety of pig breeding.
2. Improve piglet birth weight and weaning weight:
With the method of providing low nutrition level for sows in the early stage of pregnancy, gradually increasing nutrition and feed intake after pregnancy, improve piglet birth weight.
3. Early iron supplementation of piglets:
1 ml of "hematin" is generally injected into the muscle of piglets at 2-3 days of age to ensure the normal growth rate of piglets.
4. Piglets in the same litter with the original circle feeding:
Can increase the daily gain of 7~8%, shorten the time of 20~30 days.
5."Four fixed and one change" feeding:
That is, a fixed number of times, a fixed time, a fixed feeding amount, a fixed feeding standard, change the wet mix to dry powder feed pigs. Piglets are generally fed 5−6 times a day, medium pigs 4−5 times, and large pigs 3 times.
6.The use of reasonable feeding density:
Generally 0.8−1 square meters per pig is appropriate.
