Adding potassium diformate feed additive can effectively increase the daily gain and survival rate of Penaeus vannamei

 Shrimp is rich in nutrients such as protein and calcium. Various cooking methods make shrimp a common dish on the table of the common people. March to May is the main concentration time for seedlings. Everyone knows that shrimps are easy to get sick. Many people use shrimp feeds badly, which will affect the normal growth of shrimps. Today we will tell you whether the common use of potassium diformate feed additive in shrimp farming has any effect on increasing the daily weight gain and survival rate of Penaeus vannamei.

Anyone who knows how to raise shrimp knows that iridescent virus is likely to appear in Litopenaeus vannamei during this period of time, mainly manifested as jejunum, empty stomach, corpus luteum, stealing and other symptoms, and it is relatively infectious. Once something goes wrong, it is more difficult to control.

The reason why potassium diformate feed additive can play a role in promoting growth is that potassium diformate can pass through the stomach of the animal in a complete form, reach the weakly alkaline intestinal environment of the animal, and automatically decompose into formic acid and formate, Shows extremely strong antibacterial and sterilizing effects, so that the animal intestine is in a "sterile" state, thereby showing a growth promoting effect.

Potassium diformate feed additive is not only effective for the intestinal health of pigs, but also has a relatively large effect in aquaculture. The domestic aquatic microbiology research group of the Chinese Academy of Agricultural Sciences Feed Research Institute has done a series of applications of potassium diformate in aquaculture. He Suxu [12] et al. (2006) studied the effect of potassium diformate on feed conversion efficiency, growth and survival of Penaeus vannamei; the results showed that the addition of 0.8% potassium diformate can increase the survival rate by 7.8%, and the feed coefficient Decrease by 1.24% and increase daily gain by 1.3%.

At the same time, the results of the study showed that when the amount of potassium diformate increased to 1.5%, the daily weight gain and survival rate of Penaeus vannamei decreased significantly compared with the amount of 0.8% added. Zhou Zhigang et al. Carried out the influence of potassium diformate and antibiotics on the production performance of Onil tilapia. The results of the study showed that 0.3% ~ 0.6% of potassium diformate on the survival rate of Onil tilapia increased 2.5% compared with the control group. Compared with the flavomycin, quinenone, and flavin + quinocetone groups, they increased by 3.75%, 8.75%, and 5.00%, respectively. The study also showed that 0.3% ~ 0.6% significantly reduced the bait coefficient and significantly increased the rate of weight gain compared with the control group and the antibiotic group.

It is believed that farmers are still looking forward to the market of shrimps. There are more farmers who adopt the strategy of selling while waiting. However, there are many recent diseases, and the use of potassium diformate feed additive is still necessary. Shrimp is less sick, and the economic transformation of farming has naturally improved.
