The eels are sensitive and most like to eat food in the order of: earthworms, mussels, snails, fly maggots, fresh fish, etc. The eels are omnivorous fish mainly animal feed, in different growth periods, the eels' food composition is a little different.
Little eels eat egg yolks, water silk worms and earthworms.
Juvenile eels feed on waterworms, earthworms, rotifers, branchiopods, and tsetse.
Adult eels mainly feed on earthworms, small mixed fish, snail meat, mussel meat, small shrimp, tadpoles, small frogs and insects.
After reading the eel's favorite food, in fact, in eel farming in order to solve the problem of feed sources and improve weight gain, young eels and adult eels should be domesticated as early as possible to feed the artificial feed, the following let's take a look at the preparation and use of eel feed!
Artificial eel feed preparation
1, the selection of feed materials
The selection of raw materials should be in line with the principle of high quality and low price, stable source, convenient transportation. Conditions permit, the more types of raw materials, the better, so as to maximize the eel to meet the need for a variety of essential amino acids. Specifically, the choice of feed ingredients can be adapted to local conditions, for example, close to the slaughterhouse, can be based on animal offal, and then with the appropriate amount of feed.
When raising eels in a net box, you can utilize abundant and inexpensive small mixed fish and mussels as the main ingredient, plus an appropriate amount of feed to feed the eels. We can also make full use of the winter leisure time and winter land, planting some raw material crops, such as wheat, oilseed rape, etc., in order to supplement the lack of raw materials in the coming year, and then reduce the feed cost to a greater extent.
2, the rational design of feed formula
Design of the formula to consider the relationship between feed nutrition and weight, both to ensure that eels can intake of adequate nutrition, but also to let them eat.
Animal feed in the eel diet generally accounted for 50% to 70%. Raw materials such as rapeseed cake meal, although cheap, protein content is also higher, but because it contains glucoside and other anti-nutritional factors, too much use will affect the growth of eels. Therefore its dosage should not exceed 10%.
Here, we introduce you to the formula of self-mixed feed: 65% of fresh animal scraps, 20% of wheat bran, 10% of oilseed rape cake meal, 3% of yeast, 1% of salt, 1% of additives.
3, eel feed processing
We use livestock and poultry scraps as the main self-manufactured feed to introduce the production of self-manufactured feed process: the production of self-manufactured feed process generally includes crushing, mixing, granulation.
Crushing can increase the contact area of the feed and animal digestive enzymes, improve the digestion and absorption of dry matter, nitrogen and energy, reduce the feed coefficient. The method is: wash fresh meat, livestock and poultry scraps, cut into small pieces, with 3-4 mm mold hole electric meat grinder crushing. In the process of crushing, add a small amount of garlic, can play a role in disease control.
The next mix, is the crushed fresh meat, livestock and poultry scraps and a variety of additives, cake meal, bran, etc. fully mixed, stirring. We should note that in the humidity of the weather, the raw material itself has a large water content, granulation, you can properly reduce the amount of water; less humid weather can be appropriate to add more water. The general principle is: after the addition of water, the mixture of hand pinched into a ball, let go that is scattered.
Finally, the electric granulator is used to make pellet molding. Here, but also to remind the majority of farmers, self-mixed feed storage time is shorter, it is best to mix now use. #p#Subtitle#e#
What do eels eat to grow faster
The eel is an omnivorous fish with animal food as its main ingredient, and under natural conditions, it mainly feeds on small fish, shrimp, small mussels, small snails, insects, and large zooplankton such as dendroids, copepods, rotifers, etc., and swallows small frogs and tadpoles, and sometimes eats some duckweed, wild rice, and filamentous algae, too. Artificial eel farming, mainly to earthworms, fly maggots, small fish and shrimp, animal offal, slaughter scraps, with feed and bran, rice, rice bran, soybean cake, tofu dregs and melon and fruit peels and other fresh feed to feed, and can not be fed with corrupt and spoiled feed. It is best to mix animal and plant feeds into pellet feed after crushing. The size of the pellets should be based on the size of the eel, generally to a mouthful can be swallowed as appropriate. The eel ingests food in a slurping fashion, swallowing it without chewing, and when it comes to larger food, the eel bites down on it, often rotating its body in a way that breaks the food. In the eel feeding season, such as the lack of feed, eels will also eat eels smaller than themselves. Therefore, when stocking, we should choose the eel species with the same size specification and avoid mixing the size.
The eel's choice of bait is relatively strict, and it is difficult to change its original diet after feeding a bait for a long time. Therefore, in the early stages of feeding to do a good job of taming the bait, that is, feeding a wide range of sources, low prices, long supply time, high rate of meat mixed feed.
