Application and mechanism of feed-grade calcium formate in pig feed
Reduce the acidity of the feed system, lower the PH value in the stomach, and improve the activity of digestive enzymes
Each enzyme has its adapted pH value environment, and the adapted pH value of pepsin is 2.0~3.5. When the pH value is greater than 3.6, the activity is significantly reduced; when the pH value is greater than 6.0, pepsin is inactivated. The addition of calcium formate in animal feed can reduce the PH value in the stomach, thereby activating pepsin and promoting protein decomposition. The decomposition of protein can stimulate the duodenum to secrete more trypsin, so that the protein is completely decomposed and absorbed, and the feed is improved. Conversion rate,
Early weaned piglets have insufficient gastric acid secretion, and the pH value of the piglet feed is often between 5.8 and 6.5, which often makes the pH value in the piglet stomach higher than the appropriate range of pepsin activity, which affects the digestion and absorption of the feed by the piglet. Adding calcium formate to piglet feed can improve the growth performance of piglets.
Domestic research shows that adding 1~1.5% calcium formate to the diet of piglets can prevent diarrhea and diarrhea, increase survival rate, increase feed conversion rate by 7~10%, feed consumption drop by 3.8%, and pig’s daily weight gain 9~13%; adding calcium formate to the silage can increase the content of lactic acid, reduce the content of butyric acid, and increase the nutritional content of the silage.
For example: Professor Xu Wanxiang's research showed that adding 0.9% calcium formate in the piglet diet can reduce diarrhea, and adding 1.3% can increase the feed conversion rate and the growth rate of the piglet. Professor Wu Tianxing and others selected 42 piglets weaned on the 35th day according to the breed "sex". The weight of the control group and the experimental group respectively! The experimental group was supplemented with an acid protease 100000IU/KG diet and 1.0% calcium formate! The results showed that! Acid protease and calcium formate can increase the daily gain of weaned piglets by 23% (P＜0.01) and 17.2% (P＜0.01) and significantly reduce the rate of diarrhea in weaned piglets (P＜0.01)
