Due to the large increase of lobster culture area, the purchase price of lobster origin is low, and the minimum price of $456 red shrimp is only 7 ~ 8 yuan, hovering around the original price. Its own lobster production is generally only about 300 Jin per mu, and only one season of shrimp is raised in a year, so at least the profit per Jin of shrimp in 5 yuan can cover half a year's hard work. Ponds for planting saplings at home are more profitable, so slowly some farmers began to reduce their expenses. The first idea is to reduce the feed supply. Some farmers even stopped feeding the pumpkins they planted. Let's analyze whether we need to feed today's low-priced market. Can't we use beans or pumpkins instead?

All kinds of breeding varieties are basically based on feeding, which is unreasonable. First of all, the feed is comprehensive in nutrition, stable in source, convenient to obtain and use, higher in price than ordinary bait, but more reasonable. Can't you feed soybeans, ice fish, pumpkins and other bait? The answer is yes. Soybean, chilled fish and pumpkin can all be ingested, digested and absorbed by lobsters. Of course, their nutrition is different and they all have some shortcomings. For example, soybeans and protein are high in content, but raw beans have anti-nutritional factors. Long-term consumption will cause crayfish enteritis, leading to decreased digestion and absorption ability, weak constitution, decreased disease resistance, less meat in the kernel and easy to get sick. If the soybeans are cooked before feeding, the workload will increase and the price of soybeans will not be low. Therefore, compared with feed, the cost performance is not high.

In terms of food preference, crayfish prefer meat, that is, animal protein. Many people catch lobsters when they are young. They can catch lobsters with earthworms, snails, frogs, snake intestines, chicken farms, fishing grounds and shrimp skins, but they can't catch lobsters with aquatic plants or feed. Therefore, food preference is obvious. There are two kinds of feed commonly used in crayfish culture. One is special commercial feed for crayfish, and the other is soybean. Feeding density of corn. The purpose of our breeding is to increase lobsters as soon as possible. If you want to gain weight, you should increase the intake of protein. Both commercial feed and soybean belong to high protein feed. The main component of corn and wheat is starch, and the conversion product is carbohydrate, which is mainly used to supplement calories, so the cost is lower than that of feed and soybean, but it is not suitable for fattening.

In recent years, the shrimp commercial feed market has become a battlefield for major enterprises. At present, there are more enterprises producing shrimp feed in China than cattle hair, and there are more than 2 ~ 300 brands. Personally, I suggest choosing one or two of several big factories. There are too many brands. Open your eyes. Generally speaking, the products of large enterprises are more secure in quality and credit. In order to keep the price advantage, many small factories have to write articles about protein content. Mainly the ratio of soybean meal to fish meal, followed by product production technology. Crawfish feed is not a high-tech product of meat. Generally, enterprises capable of producing other animal feed can produce crayfish feed. As we all know, it includes Shang Tong, Haida, Zheng Da and Cargill. Of course, there are also prominent regional brands in the field of crayfish feed.
