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.

What role will industrial grade sodium hexametaphosphate manufacturers play in the future coating industry?

图片
The keyword in 2019 is environmental protection and safety. In 2020, environmental protection and safety hurricanes will be more violent. In the manufacturing industry, whether it's packaging, printing, furniture, shipping industry or the phosphate raw material manufacturing enterprises like Chongqing Chuandong Chemical Group that produce  industrial grade sodium hexametaphosphate , it's a good choice to withstand the environmental storm and the obvious environmental protection conditions of the enterprise itself. Take the paint industry for example, the current paint market can be found that although the domestic paint industry has achieved rapid development and formed a certain industry scale, but in the domestic high-end paint market, the domestic paint brands or enterprises are indeed few, and the domestic high-end paint market is still occupied by most of the market share of imported brands. In fact, all industries need to use coatings, and environmental protection coating

What is the use of calcium formate industrial grade in construction? The manufacturer tells you

  With the development of the city's economy, the construction of highways, bridges, tunnels, and civil construction projects will require stricter use of early strength agents. Especially in winter, in order to improve the construction period, the cement mortar needs to be raised as soon as possible and put into use.   Calcium formate industrial grade   is a good early strength agent. Although both calcium formate and calcium chloride are calcium salts, relatively speaking, the performance of calcium formate is more stable. Because the formic acid in calcium formate is a weak acid. The solution will be weakly alkaline during the hydrolysis in the aqueous solution. It can be widely used in mortar. Calcium formate industrial grade is now a newly developed low temperature early strength accelerator in China, which has been widely used in various construction cement mortars. The earliest known and used chlorine salt early strength agent in construction, but the chloride salt early str

The effect of calcium supplement with feed grade calcium formate is good when crops are short of calcium

  Is it true that crops also need calcium supplements? it is true. Crops are plants, like humans and animals, that need rich trace elements to help them grow. When crops are calcium-deficient, plant growth is hindered, and the internodes are shorter, so they are generally shorter than normal plants and have soft tissues. Since calcium has such a big effect, is it good to use   feed grade calcium formate   to supplement calcium? The meristems such as the apical buds, lateral buds, and root tips of crops with calcium-deficient plants first appear nutrient deficiency, which is perishable, the young leaves are curled and deformed, and the leaf edges begin to turn yellow and become necrotic. For example, calcium deficiency can cause leaf scorch disease in cabbage, cabbage and lettuce; tomato, pepper, watermelon, etc. have heart rot; apples have bitter pox and water heart disease. No matter how much is useless, the crops are short of calcium. If we want to achieve the actual effect, what sho
