Application methods of probiotics in pig production
I. Suckling piglets
After piglets are born, the intestinal microecological balance has not yet been fully established, and their ability to resist disease is relatively weak. At this time, introducing probiotics into the animal's body produces the best effect. Therefore, after piglets are born, first wipe their whole body clean with clean disinfected gauze or a towel, then place them in a 32°C warming box for 20 minutes to let them adapt to the outside environment and temperature, then give each piglet 2 ml of Zhilibao oral liquid (Lactobacillus acidophilus, antiviral antibodies) orally; or 2 ml of Gannuotai oral liquid (containing Bacillus and toxoid) orally, once a day for 2 consecutive days. After oral administration, place the piglets back in the warming box for 10 minutes, then let them suckle colostrum; when piglets start eating (creep feeding) at 7 days of age, add 200 g of Kangyuan No. 1 (composed of Bacillus, lactic acid bacteria, Enterococcus and their metabolites, various enzymes, bioactive factors, special adjuvants, specially formulated for suckling piglets) per 1 ton of feed, and feed continuously for 12 days; or mix 500 g of Zizhubao (a probiotic preparation specially formulated for piglets) with 500 kg of feed and feed continuously for 12 days. This can effectively prevent the occurrence of piglet yellow and white scours, improve piglet survival rate and immunity, promote weight gain, and accelerate growth.
II. Weaned piglets
For weaned piglets, you can use 200 g of Kangyuan No. 1 specially formulated for piglets diluted in 2 tons of water and drink continuously for 12 days, or 200 g of Weitai C211 (a probiotic preparation specially formulated for piglets) diluted in 2000 liters of water; or 200 g of Jinweipei C211 (a probiotic preparation specially formulated for piglets) diluted in 2000 liters of water, or 200 g of Weanlingbao (a probiotic preparation) diluted in 2000 liters of water, and drink continuously for 12 days. When piglets are weaned, the sow first leaves the farrowing crate and the farrowing room, the piglets stay in the farrowing room for 5 days and drink the solution for 5 days, then are moved to the nursery house for rearing and continue drinking the solution for 7 days. This can effectively prevent diarrheal diseases and respiratory diseases in piglets, reduce weaning stress, nutritional stress, feed stress, temperature stress and environmental stress, improve piglet immunity and disease resistance, ensure the immune effect of vaccines, and piglets grow fast, have good coat color, and have a high survival rate.
After stopping the water supplementation, nursery piglets return to normal rearing, and probiotics can continue to be added to the feed. Because weaning, group transfer, feed changes and sudden weather changes can easily cause digestive tract dysfunction in animals, manifesting as reduced feed intake, poor digestion and absorption, abnormal defecation, slow growth, dull coat, and even emaciation. At this time, you can use Ti Kang Su (a compound probiotic feed additive specially formulated for piglets) F231 developed by Jiangsu Sanyi Bioengineering Co., Ltd., 400 g mixed with 1 ton of feed, and feed continuously for 1 month. This can rapidly establish a complete intestinal microecological system, regulate intestinal balance, improve immunity, reduce disease incidence, improve the growth rate and uniformity of nursery piglets, and increase the survival rate.
III. Finishing pigs and replacement breeding pigs
After nursery piglets are transferred to the finishing house and replacement breeding pigs are introduced into the pig house, probiotics can immediately be added to the feed or drinking water and fed for 1 month, then added once more in the mid-finishing period until the pigs are marketed (replacement pigs are transferred to the breeding house). Use the probiotic preparation Kangyuan No. 1 (specially formulated for finishing pigs) at 200 g mixed with 1 ton of feed or diluted in 2 tons of water; or 200 g of Kanglejian mixed with 1 ton of feed; or 100 g of Peilejian mixed with 1 ton of feed; or Ti Kang Su (a compound probiotic feed additive specially formulated for finishing pigs) F231, 400 g mixed with 1 ton of feed, or diluted in 2 tons of water, and feed or provide as drinking water continuously for 1 month. In the mid-finishing period, the above probiotics can be used repeatedly, continuously until marketing. This can effectively improve feed utilization rate and absorption rate, improve the growth rate of finishing pigs, bring marketing forward by 10-12 days, reduce the feed-to-meat ratio by about 0.8%, reduce stress, relieve immune suppression, improve immunity and disease resistance, and also prevent digestive tract and respiratory diseases, improve carcass quality, and improve meat quality.
IV. Pregnant sows
Adding probiotics in early pregnancy of sows can effectively reduce pregnancy stress, reduce immune suppression, improve sow immunity and disease resistance, and at the same time improve the sow's nutrition and physique, increase conception rate, and allow embryos to implant safely and develop healthily. Using probiotics in mid-pregnancy can prevent the occurrence of sow reproductive syndrome, benefit the health of the sow and piglets, ensure normal fetal development, and reduce the stillbirth rate by more than 95%. Adding probiotics in late pregnancy, especially in the 1 week before and after farrowing, helps ensure safe farrowing of sows, sufficient milk, healthy piglets, and a high survival rate. At the same time, it can also effectively prevent the occurrence of the "three inflammations" in sows, namely endometritis, vaginitis, and mastitis, as well as prenatal constipation and anorexia in sows. Directions for use: the sow-specific probiotic preparation Kangyuan No. 1 at 200 g mixed with 1 ton of feed or diluted in 2 tons of water; the sow-specific Ti Hang Su (a compound probiotic feed additive) F231, 400 g mixed with 1 ton of feed or diluted in 2 tons of water, fed or provided as drinking water continuously; you can also choose Sowbao or Sowkang or Jinweipei C231, etc., each 500 g mixed with 1 ton of feed or diluted in 1500 liters of water; or use the sow-specific Weitai C231, each 200 g mixed with 1 ton of feed or diluted in 2 tons of water, and it can be used continuously.
V. Post-illness pigs
When animals suffer from multiple diseases, large amounts of antibacterial drugs are used for treatment. While killing a large number of harmful bacteria, this also causes beneficial bacteria in the animal's intestinal tract to be killed. After medication ends, harmful bacteria rapidly multiply again, and at this time it is very likely that the animal's disease will recur. Therefore, after the animal finishes antibacterial drug treatment, probiotics should be used promptly. This can effectively prevent harmful bacteria from multiplying again, allow the animal's intestinal environment to reach a state of bacterial flora balance as quickly as possible, and reduce disease recurrence. At the same time, it also helps accelerate the recovery of pigs after illness.
