What causes slow growth in pigs?
What exactly causes slow growth in pigs?
Pig farmers hope for a good price, and the next thing they hope for is for pigs to grow faster. The shorter the time needed, the better; the less feed used, the better; and the fewer diseases, the better. This is thepig farmer'smentality, and that is no exaggeration at all. People should not expect too much; they should raise pigs in a down-to-earth way. Everything is achieved step by step. How can there be so many cases of “pie falling from the sky”? When it comes to shortening the feeding cycle, scientifically pigs should be marketed at 110 kg, but what happens in reality? If they do not reach 280 jin, farmers simply do not want to sell, because only then will pig traders come to buy them. Is not the gap between theory and reality just the price difference of about 100 jin of feed? Do you still remember when pig prices were low? On average, they were sold at 100 kg. This is the reality of pig farming! No change, no innovation!
Let us continue and talk about what causes slow pig growth and a prolonged marketing period.
1. No good breed. It is recommended to use purebred stock, and this problem can be solved through good crossbreeding.
2. The quality of the feed. It is recommended to choose a larger brand of feed, since the raw materials are not easily changed.
3. The farrowing stage and birth weight of piglets absolutely affect the marketing time. Birth weight affects weaning weight. Next is the problem of yellow scours disease in newborn piglets during the farrowing stage. Once diarrhea starts, it lasts three or four days, and from losing condition to full recovery, it will add at least 7--10 days to the marketing time.
4. Stress diarrhea in piglets at the weaning stage will also extend the marketing period by 7--10 days back and forth. If weaning diarrhea is well controlled, piglet mortality can be reduced by 10%.
5. Preventive use of large amounts of antibiotics. Antibiotics also have side effects, namely inhibiting growth, affecting intestinal flora, hindering the absorption of feed nutrients, affecting the absorption of vitamins and trace elements, and also affecting the absorption of calcium in the feed. All of these will lead to a later marketing period for pigs.
6. Incomplete deworming. In recent years, parasites have been another invisible killer harming the breeding industry. The presence of parasites affects the digestion, absorption, and utilization rate of feed. In ordinary practice, deworming is basically done for one day. Pig Manager tells everyone that it must be seven days. Seven days this month, seven days next month. Each batch of piglets should be dewormed four times, twice during nursery and twice during fattening; sows twice a year; piglets should start deworming three days before weaning. This will not affect the sow's estrus and mating. Only in this way can parasites be thoroughly eliminated.
