Preparation and use of Monopterus Albus Feed

Monopterus albus is a valuable freshwater fish species, artificial culture benefit is high. Feed is one of the biggest costs in the artificial culture of eel. With the rise in commodity feed prices, in order to reduce feed costs, more and more farmers have begun to use agricultural and sideline products to prepare their own feeds. So, how to choose the right feed formula? What scientific feeding methods are there? Below, we will make some introductions to you.

Preparation of Artificial Compound Feed for Monopterus albus

1. Selection of feed raw materials

Selection of raw materials should be based on the principle of high quality and low price, stable supply and convenient transportation. If conditions permit, the more kinds of raw materials, the better, so as to meet the needs of eel for various essential amino acids to the maximum extent. Specifically, when selecting feed raw materials, it can be adapted to local conditions, for example, close to the slaughterhouse, it can be mainly animal internal organs, and then add appropriate amount of feed. When rearing finless eel in net cage, we can use abundant and cheap small miscellaneous fish and clam meat as main materials, and add appropriate feed to feed finless eel. We can also make full use of winter fallow time and winter fallow land to plant some raw material crops, such as wheat and rape, to supplement the shortage of raw materials in the coming year and reduce feed costs to a greater extent.

2. Reasonable design of feed formula

When designing the formula, the relationship between feed nutrition and bulk density should be considered, which should not only ensure that the eel can absorb sufficient nutrition, but also make them full.

Animal feed generally accounts for 50%~70% of eel diet. Although rapeseed meal is cheap and has high protein content, it contains anti-nutritional factors such as glucosinolate, which will affect the growth of eel if used too much. Therefore, its dosage should not exceed 10%.

Here, we introduce the formula of self-prepared feed: fresh livestock waste 65%, wheat bran 20% , rapeseed cake 10%, yeast 3%, salt 1%, additives 1%.

3. Processing of eel feed

We introduce the process flow of producing self-made feed by using livestock scraps as the main self-made feed: the process flow 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.

washing fresh meat and livestock waste, cutting into small pieces, and crushing with an electric meat grinder with a die hole of 3-4 mm. In the process of crushing, add a small amount of garlic, can play a role in disease control. Next, the crushed fresh meat, livestock waste and various additives, cake meal, wheat bran, etc. are fully mixed and stirred.

We should note that in the weather with higher humidity, the moisture content of the raw material itself is large, and when granulating, the amount of water added can be appropriately reduced; in the weather with lower humidity, more water can be added appropriately. The general principle is: after adding water, the mixture is kneaded into a group and released. The most important is to use electric granulator granulation molding. Here, but also remind the majority of farmers friends, self-prepared feed storage time is relatively short, it is best to use now.

Use of feed for eel

The feeding principle of eel should be fixed time, fixed quantity, fixed quality and fixed position.

1."Timing" is based on the daily habits of eel, feeding once at 10:00 a.m. and 6:00 p.m. every day, mainly in the afternoon.

2,"quantitative" is based on the relationship between the feeding intensity of eel and water temperature, to determine the amount of daily feeding. Generally speaking, when the water temperature is about 15℃, start feeding, the daily feeding amount accounts for about 3% of the body weight of the young eel; 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 body weight of the eel; when the temperature reaches more than 30℃, less feeding or no feeding should be done. Feeding personnel should check in time 1 hour after feeding. If the bait has been eaten up, it means that the bait amount is insufficient and should be increased appropriately. If it has not been eaten up within 1 hour, it means that the bait is excessive and should be reduced appropriately.

3,"quality" is based on eel like to eat fresh bait, do not like the habit of spoilage food, to ensure that the feed must be fresh not spoilage.

4."Positioning" refers to feeding at a fixed location. In this way, the eel can form the habit of concentrated feeding, and it is also convenient for farmers to observe the feeding situation of the eel and adjust the feeding amount of bait in time.

The practice proves that feeding ricefield eel with compound feed can not only save feed cost, but also accelerate the growth speed of ricefield eel and obviously improve the economic benefit of farmers. Audience friends, you might as well try it.
