Breeding techniques and matters needing attention of nutria

Nutria is a treasure from the inside to the outside, it can not only do food, but also medicinal research value, its fur can be made into clothing, has always been a popular choice in the breeding industry. How on earth should we raise nutria? The following is to learn about the breeding techniques and matters needing attention of nutria with the editor.

The breeding value of nutria

The reason why nutria can develop into an important business in the breeding industry is mainly because of its high economic value. It is shown in the following aspects:

1. Nutria meat has no peculiar smell and high nutritional value. The fat content is low, the hemoglobin content is extremely high, the crude protein content is 25%, the calcium and zinc content is higher than the same kind of livestock and poultry meat, there are 18 kinds of amino acids, more than 30 kinds of trace elements.

2. The health drugs made according to the substances in beaver blood can effectively treat gastrointestinal diseases.

3. The medicinal wine made from the bones of nutria also has a good effect on dispelling rheumatism.

4. With the deep processing of nutria products, some high value-added products have been developed, such as nutria oil can make high-grade cosmetics.

5. Nutria fur is thick, tight and soft, with gorgeous fluff luster, good water resistance and thermal insulation, and the clothes made are of good quality and cheap, which are very popular among the working class and some countries in Eastern Europe.

6. The tail of nutria has the effect of nourishing yin and strengthening yang. After scientific treatment, the tail tendons are made into absorbable protein sutures for suturing the wound without removing stitches.

Technical operation of nutria culture

1. Breeding site preparation: there are four feeding methods for nutria, mainly: cage breeding, captive breeding, free breeding and semi-free breeding. There are differences in site preparation according to different ways. The caged houses should be well ventilated and the internal environment is dry and bright. A cage with a suitable distance is installed in the house according to the area; the size of the site is planned by a nutria of 1 square meter in captivity. It should be divided into sports eating area, rest area and swimming area. The enclosure wall is surrounded by cement and barbed wire; free culture is generally combined with natural waters to arrange the site; semi-free culture combines the characteristics of captivity and free breeding, and the feeding mode is changed according to seasonal changes.

2, feed preparation: nutria is a plant animal, feed preparation can choose cabbage, spinach, radish and so on. These feeds should be non-toxic and clean, and pay attention to the choice of quality before feeding. In addition to plant food, it can also be matched with animal feed to ensure its nutritional balance.

3. Feeding method: the feeding of nutria needs to be matched according to the season. We should diversify the types of feed, pay special attention to the supply of protein feed, supplement vitamins and trace elements, and persist in feeding salt and bone meal regularly to meet the needs of potassium, sodium, calcium and phosphorus. It is necessary to ensure the nutrition and quality of food for pregnant female rats. This period, such as undernutrition will cause stillbirth, weak birth or postpartum body deficiency, lack of milk and other adverse phenomena. The focal point of feeding mother rats during lactation is to solve the recovery of physique and ensure normal lactation. This period should give more succulent or green feed, add more protein-containing soybeans and peanuts, and drink more warm and light salt water, properly add dry yeast tablets and vitamins An and D, etc. The offspring will eat after a few hours of birth, and the offspring will develop rapidly. This period of growth requires more inorganic elements and a large amount of protein and various vitamins. Therefore, in addition to ensuring breast milk. The diet should be properly fed with milk, bone meal, soybean meal, fish meal and various vitamins to ensure that there is green feed to allow it to eat freely. Concentrate supply should be fixed and quantitative, otherwise it is easy to cause indigestion and affect development. About 50 days old can be weaned and divided into nests to provide full-price nutrition and digestible feed.

Matters needing attention in nutria culture

1. Nutria are not resistant to heat and lack the ability to tolerate direct light and muggy weather. The cover of the enclosure should be covered with mulch, such as branches, grass curtains and so on. In order to lower the temperature in summer, the pool water can also be changed frequently to keep cool. Pay attention to the cold in winter, you can transfer the nutria indoors for dry breeding.

2. Attention should be paid to keeping the breeding environment hygienic. The water should be changed 2-3 times a day, and the dirt in the water should be cleaned up in time each time. Strong self-cleaning power causes nutria to be uneasy in comparison with dirty nests, so the feces and residual food in the circle should be removed in time to prevent fermentation in the circle.

3. The life activities of animals are related to vitamins, if the lack of vitamins will reduce the activity of enzymes in the body, hinder the corresponding metabolic process, thus affecting the growth, reproduction and disease resistance of nutria.

4. in order to prevent the occurrence of diseases, some broad-spectrum antibiotics should be added to the feed, such as ciprofloxacin and enrofloxacin.

Nutria breeding technology and matters needing attention are introduced here, how to successfully raise nutria, not only to master solid theoretical knowledge, but also need reasonable and effective practical operation.
