Today, farmers still mainly use fish and shrimp as their benchmark.
The huge profits in the shrimp farming industry have led to inflated prices of raw materials, additives, feed, medicines, etc. Only when the breeding success rate rises (only a premise) can aquafeeds enter a stable state. In the past two years, thousands of aqua feed mills have collapsed in the industry reshuffle.
In the aquatic industry, the overall technology has been improved, and the success rate of breeding has increased, which has diversified the breeding of the entire industry, enhanced the buffer system, stabilized breeding profits, promoted the stability of feed, breeding and other industries, and promoted the stability of feed and breeding to promote agricultural stability.
Promotion can stabilize the entire aquatic product market, which is an inseparable relationship between the subject and the individual, and what stabilizes is the repeated shuffling of the industry until it is stable.
The quality of an aqua feed factory lies in the stability of the product
The most important thing about feed is the constant quality. This does not mean the same, but the combination of practical production and cutting-edge science and technology. The raw materials are varied and the quality is constant.
Many people may also feel that as long as the equipment is complete and the feed materials and formulas are of high quality, good feed will be produced, but the quality level of the production staff is ignored.
Many large aqua feed enterprises are developing rapidly, and they can directly use money to poach people and buy them. The best aqua feed processing equipment does not necessarily produce stable quality feed, and the aqua feed production process is not up to standard.
A mature aqua feed production line is the cooperation of various employees in the workshop for many years, and the awareness obtained after years of production. Often when people look at the quality of a feed, they can refer to the years of production of the aqua feed enterprise.
Generally, aqua feed enterprises with more than 20 years have very stable feed quality. As for the aqua feed formula, it is an aqua feed factory that combines many years of actual production and integrates cutting-edge technology. It cannot make a perfect formula overnight.
In the feed industry, as we all know, it is easy to make feed well, but it is very difficult to make stable feed. 100 people make feed, 98 people can do it well, but there are often only 1 or 2 people who can make stable feed.
Because the process control of raw materials is very uncertain, laboratory quality control standards, raw material quality control standards, etc., such as fish meal, meat meal, shrimp bran, blood meal, soybean meal, peanut meal, etc., the year, origin, purchase point, The aqua feed suppliers are different, and their quality is completely different, resulting in very different feeds in the final production.
Everyone thinks that aqua feed companies are competing with each other and that the products are the same. But in fact, feed and aqua feed enterprises are very different.
The most important thing is the balance of amino acids. According to aquatic animal nutrition combined with actual production and changes in the quality of raw materials, a feed with amino acid balance is produced. This is also a technical core issue of an aqua feed enterprise.
Now farmers are overly concerned about feed protein. An aqua feed factory is to look at the stability of its feed quality and the balance of amino acids, and feed attractiveness, disease resistance factors, shrimp survival rate, and coefficient are the key points in the evaluation of feed quality.
It is very difficult to obtain high-quality feed. A stable quality feed is the basis for successful breeding. Maybe some people here say seedlings and water quality. This involves personal opinions, so I won't explain too much.
Are aquatic feeds and shrimp feeds homogenized now?
Let's talk about the problem of feed protein (take the Chinese market as an example)
According to a large number of actual breeding data, the protein content of feed in low-density breeding is high and low, and the breeding effect is not much different. However, taking China as an example, in recent years, in shrimp breeding in northern China, even if low-density breeding, due to seedlings, etc.
The reason is that the number of prawns reached 60-90 before and after the National Day, and the price was about 10 yuan. The growth of prawns was slow, resulting in serious losses. Because of economic problems, the breeder's seed changed.
The aqua feed factory specializes in high-density breeding feed, which promotes low-density ecological breeding. It is difficult to achieve the best, and there are indeed a feed factory that has created a series of functional feeds for shrimps, which are specially designed to prevent death from stealing, jejunum, and slow growth of soil seedlings.
It has been promoted in Tianjin, Hebei and other places in China, and the breeding effect has been achieved by local farmers. Recognition, it perfectly solves the problem of slow growth of shrimp seedlings.
In high-density farming, the higher the protein, the faster the growth and the higher the benefits. At present, the crux of the shrimp farming industry is related to high-density farming and the random use of illegal drugs. High-density farming produces higher profits, and the random use of certain antibiotics can achieve good profits in a short period of time.
The environment is deteriorating day by day, the resistance of bacteria is increasing, and the success rate of farming has been declining year after year, and aquaculture has fallen into a vicious cycle.
Most of the feed protein on the market today is 42/43, but the gap between protein and protein is very large. Among them, the content of restricted amino acids and essential amino acids, animal protein, lipids, fish meal content, etc. have a lot of room for manipulation, even if the protein is the same as the feed, quality can vary widely.
At present, the Chinese standard GBT 22919.1-2008 for Penaeus vannamei is adopted (this standard stipulates that the protein of juvenile Penaeus vannamei should be ≥36%). This national standard was released on December 31, 2008 and May 2009. 1 to start executing.
However, according to the SCT 2002-2002 shrimp compound feed standard (this standard stipulates that the feed protein of Penaeus vannamei is ≥28%), the protein of high-density aquaculture feed is often more than 40, and the enterprise standard is higher than the national standard.
First, the feed is changed from Penaeus monodon Influence, first, at that time, the national promotion of Penaeus vannamei, the breeding success rate was high, and the feed profit margin was large.
(This is why some seniors in the feed industry often lamented that the shrimp feed at that time was really easy to sell), and now the protein of the feed is far from GBT22919.1-2008, SCT2002-2002, and of course the reason is "high protein" notion of shrimp has also been preconceived among farmers of vannamei, and it has become "natural" or even deeply ingrained, which makes the standard of the shrimp feed industry always follow the high-protein aqua feed enterprise standard.
Many people are criticizing that aqua feed factories have been increasing protein. Although the water pollution is more serious, high protein has indeed played a role in breeding. At present, whether it is high-level ponds or factory farming, feeds with high protein do have higher breeding benefits.
According to the national standard, the test effect also proves that in high-density farming, the growth of high-protein feed is indeed much faster than the national standard.
As for circulating aquaculture and biological floc culture, the corresponding feed should be selected according to the hardware equipment, and the general protein is about 42, which involves issues such as denitrification of water bodies.
