What's the favorite food of Monopterus Albus?

The sensitive and favorite food order of Monopterus Albus is earthworm, mussel meat, snail meat, fly maggot, fresh fish meat and so on. Monopterus Albus is an omnivorous fish based on animal feed, and the food composition of Monopterus Albus is different in different growth periods.

Young eels eat egg yolks, water worms and earthworms.

Young eels eat water worms, earthworms, rotifers, cladocera and wigglers.

Adult eel mainly eats earthworms, small fish, snail meat, clam meat, shrimp, tadpoles, frogs and insects.

After watching the favorite food of Monopterus Albus, in fact, in order to solve the problem of feed source and increase weight gain in Monopterus Albus culture, young and adult eels should be domesticated and fed artificial compound feed as soon as possible. Let's take a look at the preparation and use of Monopterus Albus feed.

Preparation of artificial compound feed for ricefield eel

1. Selection of feed raw materials

The selection of raw materials should be based on the principles of high quality and low price, stable supply and convenient transportation. When conditions permit, the more kinds of raw materials, the better, so as to maximize the need for various essential amino acids of Monopterus Albus. Specifically, when choosing feed raw materials, measures can be taken according to local conditions, for example, close to the slaughterhouse, animal offal can be mainly used, and an appropriate amount of feed can be added.

When raising ricefield eel in cage, we can use rich and cheap small mixed fish and clam meat as the main material, plus an appropriate amount of feed to feed ricefield eel. We can also make full use of winter leisure time and winter leisure land to plant some raw material crops, such as wheat and rape, to make up for the shortage of raw materials in the coming year and to reduce feed costs to a greater extent.

2. Rational design of feed formula.

When designing the formula, we should consider the relationship between feed nutrition and bulk density, not only to ensure that Monopterus Albus can eat adequate nutrients, but also to make them full.

Animal feed generally accounts for 50% and 70% of the diet of ricefield eel. Rapeseed meal and other raw materials are cheap and high in protein content, but because they contain anti-nutritional factors such as glucosinolates, excessive use will affect the growth of Monopterus Albus. Therefore, it is appropriate to use no more than 10%.

Here, we introduce the formula of self-made feed: fresh livestock and poultry scraps 65%, wheat bran 20%, rape meal 10%, yeast 3%, salt 1%, additive 1%.

3. Processing of Monopterus Albus feed

Based on the use of livestock and poultry scraps, we introduce to you the technological process of producing self-made feed: the technological process of producing self-made feed generally includes crushing, mixing and granulation.

Crushing can increase the contact area between feed and animal digestive enzymes, improve the digestion and absorption of dry matter, nitrogen and energy, and reduce feed coefficient. The method is: wash the fresh meat, livestock and poultry scraps, cut them into small pieces, and crush them with an electric meat grinder with a 3-4 mm mold hole. In the process of crushing, adding a small amount of garlic can play a role in preventing and controlling diseases.

The next step is to mix and stir the crushed fresh meat, livestock and poultry scraps and various additives, cake, wheat bran and so on. We should note that in the weather with high humidity, the water content of the raw material itself is high, and the amount of water added can be appropriately reduced during granulation, while more water can be added appropriately in the weather with low humidity. The general principle is: after adding water, the mixing hand is squeezed into a ball and let go.

Finally, the electric granulation mechanism is used for granulation. Here, we should also remind the broad masses of farmers that the storage time of self-made feed is relatively short, and it is best to match it now.

The use of Monopterus Albus Feed

In the breeding process of Monopterus Albus, the "four definite" principles of timing, quantity, quality and orientation should be adhered to.

1. According to the living habit of Monopterus Albus, Monopterus Albus was fed at 10:00 and 6 pm every day, mainly in the afternoon.

2. "quantitative" is to determine the daily feeding amount according to the relationship between the feeding intensity of Monopterus Albus and the water temperature. Generally speaking, when the water temperature is about 15 ℃, the daily feeding amount accounts for about 3% of the young eel's body weight; when the water temperature is 15-20 ℃, the daily feeding amount can be increased to 6%-10% of the body weight; when the water temperature is 20-28 ℃, the daily feeding amount accounts for 10%-20% of the rice field eel's body weight; when the temperature is above 30 ℃, bait should be reduced or not. Breeders should check in time 1 hour after feeding, if the bait has been eaten, it shows that the amount of bait is insufficient, it should be increased appropriately, if it is not finished in 1 hour, it means that the bait is excessive and should be reduced appropriately.

3. "quality" is based on the habit that Monopterus Albus likes to eat fresh bait and does not like spoiled food, so it is necessary to make sure that the feed is fresh and not spoiled.

4. "location" refers to feeding at a fixed location. This can make Monopterus Albus develop the habit of concentrated feeding, and it is also convenient for farmers to observe the eating situation of Monopterus Albus and adjust the amount of bait feeding in time.

The practice shows that feeding Monopterus Albus with compound feed can not only save the feed cost, but also accelerate the growth rate of Monopterus Albus and significantly improve the economic benefits of farmers. Dear viewers, you might as well have a try.
