Application of potassium dicarboxylate in aquatic production
After adding 0.2% and 0.5% potassium dicarboxylate to the diet for 10 weeks, its body weight increased by 7.2% and 7.4% (p<0.05), the productivity index was significantly higher than that of the control group (p<0.05), and the specific growth rate and weight gain were higher than that of the control group (p>0.05). However, the addition of 3.0g/kg, 6.0g/kg and 12.0g/kg potassium dicarboxylate to the feed did not affect the growth performance, feed conversion rate and survival rate of hybrid tilapia, but the final weight and specific growth rate of hybrid tilapia in the 3.0g/kg group and the 6.0g/kg group were higher than those in the antibiotic group (4mg/kg flavin + 50mg/kg quinosterone).
Ramli et al. (2005 [40]) reported that the growth-promoting effect of potassium dicarboxylate as a non-antibiotic growth promoter on fish was studied in the onionic oleifera grow-out trial conducted in Indonesia. 320 male marine cultured tilapia were randomly assigned to four experimental treatment groups and fed six doses of potassium dicarboxylate (0, 2, 3 and 5 kg per ton of feed) six times a day during the 85-day trial. On the 10th day of the breeding period, fish were given oral administration of Vibrio eels (number of live bacteria: 105cfu/d) for 20 consecutive days. From the overall effect, the weight gain effect of the test fish fed to the experimental treatment group containing potassium dicarboxate was remarkable, and the effect on the growth of tilapia was obvious. Compared with the negative control group, tilapia in the experimental group fed 2 kg of potassium dicarboxylate per ton of feed increased the feed intake rate (8.6%), increased the percentage of net weight gain of the fish body (18.6%), and improved the feed conversion rate (8.2%). In addition, data analysis also showed that potassium dicarboxylate was effective in controlling bacterial infections (reducing mortality due to Vibrio eels). Survival rates of oral eel-stimulated tilapia increase with increasing levels of potassium dicarboxylate added doses.
He Suxu et al. (2006 [41]) studied the effects of different levels of potassium dicarboxylate in feed on the production performance of Penaeus vannamei dioxide, and the addition of 0.8% potassium dicarboxylate in the diet could increase the total weight of Penaeus vannamei by 20.6%, increase daily weight gain by 26%, and increase survival rate by 7.8%. The experimental results show that the addition of 0.8% potassium dicarboxate to the feed of Penaeus vannamei can significantly improve the growth of shrimp and increase the survival rate of shrimp.

lückstädt c. (2006[42]; The tilapia test summary in 2007 [43]) further confirmed the role of potassium dicarboxylate in killing harmful bacteria, promoting the growth rate of fish and shrimp, and improving the survival rate of aquatic animals.
The addition of potassium dicarboxate to the feed of pond cultured Penaeus vannamei as a nutritional substitute for modern penaeus vannamei is an effective way to improve the growth of penaeus vannamei in sugar culture.
finish
Potassium dicarboxylate as a simple organic acid acidifier in the application of piglets to achieve good results, may be due to the young piglet gastrointestinal development is not yet complete, gastric acid secretion is small, the pH in the stomach is relatively high, the addition of potassium dicarboxylate effectively reduces the pH value in the stomach of piglets, inhibits the growth and reproduction of harmful microorganisms, improves the intestinal health of piglets, and improves its growth performance. However, due to the influence of the synthesis process and purity of potassium dicarboxylate products, the appropriate dosage needs to be further determined, and if the amount of addition is too large, it will reduce the production performance of weaned piglets. Sow test found that potassium dicarboxylate is mainly used to increase the amount of feeding intake during sow lactation and reduce the loss of dorsal fat during lactation, shorten the number of days when sows are weaned to estrus, and help improve the reproductive performance of sows. In addition, potassium dicarboxate has a certain effect on improving the growth performance of broilers, reducing necrotizing enteritis and improving the specific growth rate of Penaeus vannamei.
