Pigs pay attention to the key "three days"
Three days after breeding
Three days after mating, it is a crucial period for egg fertilization and fertilized egg splitting. If the sow is over-saturated at this time, part of the fertilized egg will die, which will reduce the number of births. Therefore, sows should not be fed too much within three days after mating, and the daily feeding amount should be 1.5 kg - 1.8 kg, and no more than 2 kg.
Three days after childbirth
For newborn pigs, feeding and management after three days of delivery are of the utmost importance because many casualty accidents during the pig raising process occur at this stage, such as freezing, frostbite, crushing, and death. In order to reduce the pig's death and injury rate in these three days, the following tasks should be done:
1. Proper production and warmth and moisture protection.
2. Let the newborn pig eat colostrum in time to enhance disease resistance.
3. Fix the teat.
4. Timely iron and selenium supplements to prevent selenium deficiency and anemia.
5. Restore sow body condition to prevent postpartum infection.
Three days after weaning
This is the most severe period of stress in weaned pigs. The imported food was changed from liquid milk to solid feed, leaving the sow's care. At the same time, because the sow was driven away, the shepherd's temperature was greatly reduced and the maternal antibody was stopped. Each of the above stresses will have a very adverse effect on the pig and become an inducement for its onset. Reducing stress is the key to helping the pigs to wean properly. Drug prevention is an effective supplementary measure to prevent secondary infection of the pigs. Comfortable environmental conditions and high-quality feeds are the guarantee for successful weaning.
Three days after transfer
The new feeding environment will cause physiological and psychological adaptations to the pigs, and the disease resistance will also be reduced. The nests of different litters will re-establish their status in this new group after "combination". At the same time, the three positions of the pig's sleep will be completed within these three days, all of which will consume a lot of energy. In order to ensure the successful transfer of pigs, the following work should be done.
1. Keep the ambient temperature before the transfer as close as possible to the new environment.
2. Feed the original feed for a period of time until all the pigs are stable and gradually change to feeds for the finishing period.
3. Strengthen drug prevention to prevent pathogens from invading the pig body.
4. Fighting phenomenon often occurs after the mixed group of pigs, so, for some varieties with greater stress response, attention must be paid to the precautions when changing groups.
RP International Ltd is top Gellan Gum Supplier and Manufacturer in China.
Gellan gum is a water-soluble anionic polysaccharide produced by the bacterium Sphingomonas elodea (formerly Pseudomonas elodea). The gellan-producing bacterium was discovered and isolated by the former Kelco Division of Merck & Company, Inc. in 1978 from the lily plant tissue from a natural pond in Pennsylvania, USA. It was initially identified as a substitute gelling agent at significantly lower use level to replace agar in solid culture media for the growth of various microorganisms .Its initial commercial product with the trademark as "GELRITE" gellan gum, was subsequently identified as a suitable agar substitute as gelling agent in various clinical bacteriological media.
