What are the common pig feed additives?

Pig feed additives are generally divided into drug feed additives, antibiotic feed additives and microbial additives, in which drug feed additives and antibiotic feed additives have drug residues and can kill most of the beneficial bacteria in animals. it is very disadvantageous to the growth and development of animal immune system, easy to produce drug resistance, and the raised animals are not very good in terms of coat color or edible flavor. Microbial additive is a new type of feed additive which is healthy, environmentally friendly, green and without drug residues. What are the commonly used pig feed additives?

1. Pine needle powder

Pine needles contain 19 kinds of amino acids and are rich in carotene, vitamins, trace elements and antimicrobial pine needle antibiotics. By adding 5% pine needle powder to pig feed, the daily gain can be increased by 18-30%, and the fattening period can be shortened by 30-60 days.

2. Mirabilite

When 0.5-0.6% mirabilite is added to the pig feed, the daily gain is increased by 20%, the feed utilization rate is increased by 15%, and the pig is healthy and less sick, the fur is bright, the appetite is strong, and the stool and stool are normal.

3. Kelp powder

Kelp is rich in iodide and minerals, vitamins and active ingredients that stimulate animal growth. When 2% kelp powder was added to the pig feed, the daily gain could be increased by 23% and the feed conversion rate could be increased by 13%.

4. Zeolite

Zeolite is a kind of hydrous silicate mineral, which contains all the major elements and most trace elements necessary for the growth and development of pigs. By adding 1% zeolite powder to pig feed, the average weight gain of pigs can be increased by 10%.

5. Orange peel powder

Orange peel powder has a variety of nutrients, which can increase animal appetite, promote rapid growth and enhance disease resistance. Adding 5% orange peel powder to pig feed can increase daily gain by 12%, reduce feed consumption by 0.28 kg for each weight gain, increase feed reward by 10.5%, and increase carcass weight and net meat weight.

6. Evergreen

Evergreen contains more than 40 ingredients such as plant antibiotics, plant auxin, protein and vitamins. If 3-5 grams of evergreen are added to every 100 kg of feed, the daily gain can be increased by 20-30%.

7. Silkworm sand

Adding 5-10% silkworm sand to pig feed can increase daily gain by 10-15%, feed conversion rate by 15-20%, and pig growth is good, coat color is bright, and the occurrence of pig disease can be reduced.

8. Copper sulfate

Adding 0.25% copper sulfate to pig feed can increase pig daily gain by 16%, feed utilization rate by 5%, and feed cost by about 4%.

9. Earthworm powder

Each pig is fed only once a day, adding 10-20 grams per day and 30-50 grams per day, which can increase the daily weight gain by 10-15%.

10. Zinc sulfate

The addition of 10-20 mg per pig and 30-50 mg per pig per day can accelerate the growth of pigs, exuberant appetite, smooth fur and less morbidity and death.

11. Microbial feed additive

Microbial feed additive is a kind of feed additive approved by the Ministry of Agriculture, which plays a useful role by improving the ecological balance of animal intestinal flora, so as to improve animal health, disease resistance and digestive ability. the spread of diseases, drug resistance of bacteria, decline of immune ability, reduction of survival rate and decrease of breeding efficiency are the effective means for the sustainable development of animal husbandry.
