Due to the imperfect function of the digestive tract of the pig's gastrointestinal tract, after the early weaning of the pigs, part of the feed will not be digested when the pigs are fed. This will cause a burden on the digestive system of the pigs, which will lead to diarrhea and affect the growth of the pigs. . If an appropriate amount of organic acid is added to the pig material, healthy growth of the piglet can be promoted and the survival rate of the piglet can be increased.
Gastric acid is an acidic secretion secreted by the cells of the gastric fundal glands of the livestock. It has the effect of activating pepsinogen, promoting the secretion of pancreatic juice, bile, and gallbladder, promoting the digestion and absorption of nutrients, and inhibiting the growth of harmful microorganisms.
It was determined that the pigs had insufficient gastric acid secretion at the age of 8 weeks. The pH in the stomach was about 3.1 at the 20th day of age, and the pH was about 4.0 at the 30th day and was weakly acidic. The pH value of adult pig stomach juice is 1.1-1.8, and its acidity is strong. Only when the gastric juice pH test showed that 2% citric acid was added to the pig diet, the weight gain in the test group was 15% higher than in the control group, and the feed utilization efficiency was increased by 9%; 2% lactic acid was added to the piglet diet. The group gained 11% more than the control group. Addition of 1% to 2% of organic acid in the sub-pig feed below 30 kg is most suitable, and its effect is obvious.
1.Good safety of gelatin-free.The first lyophilized Varicella Vaccine, containing no gelatin from animals, invented and produced in China. Getting rid of gelatin from varicella vaccine can significantly decrease the ratio of anaphylaxis incidence .
2.Long validity period by good stability. The first approved varicella vaccine with 36 months of validity period in the world. Adopting BH-2 stabilizer with own IP rights (Chinese patent granted No.: ZL200910138411.6, International patent application No.: PCT/CN2009/001405) greatly enhances the stability of the product and ensures the validity period for 36 months under the storage condition.
3.Better protection with high titer and immune eff
icacy. It`s documented that compared with the varicella vaccine of low titer, high titer vaccine can reduce breakthrough cases by nearly 75% in vaccination. Of all released batches of Varicella Vaccine from BCHT, the titers are not less than 10000 PFU/dose tested by National Institutes for Food and Drug Control.
