How to raise nutria?

Basic knowledge of feeding and breeding management nutria:

A, the daily management of nutria.

1. Concentrate should be fed regularly and quantitatively, only 7-8 minutes at a time, green material should be fully supplied, and

2. To ensure that the feed environment is quiet, gradually touch and domesticate, so that it is not afraid of people, does not bite people, and can actively approach people to eat. Domestication is of great value in giving birth, improving economic efficiency and appreciation.

3. The enclosure and appliances should be cleaned and disinfected frequently, and the grass in the nest should be changed frequently to prevent flies and mosquitoes from biting. The rodents should be checked regularly every day, and the hostile mice should be separated in time when the phenomenon of fighting and biting is found. The estrus mother mice should be mated in time, and the sick rats should be isolated and treated. If the mouse is found to run the circle, the ring wall should be repaired in time.

4. Always keep the pool water clean. In the disease-prone season, antibiotics, vitamins and other preventive drugs can be added to the feed.

B, the four seasons management of nutria.

1. Summer temperature is high and humid, mosquitoes and flies are numerous, and it is easy to get sick. Special attention should be paid to sunshade prevention and cleaning work. To ensure that the feed is fresh, the diet should be fed with green feed, reduce the concentrate accordingly, and reduce the density of rodents. The pool water is changed frequently and kept clean. Enclosures and nests should be cleaned once a day and disinfected weekly.

2. The weather is cool in autumn, but there is a big temperature difference in the morning and evening, and it is hot at noon, so we must do a good job of shading at noon and increase the bedding grass in the nest at night. This period is an important season for the growth and development of mice, the feeding amount can be increased appropriately, and more succulent feeds such as fruits and vegetables can be fed.

3, the winter weather is cold, the key point is to do a good job of heat preservation, the fence house is equipped with wind-cold barrier, the nest is filled with soft dry grass and close the door. There is no need to remove the weeds on the playground to prevent the rats' claws from freezing on the cement floor. During the freezing winter, the water in the pool should be drained. The diet is composed of hay, concentrate and supplements. At the same time, group breeding can be carried out to increase the density of rodents.

4. Spring is the season of frequent occurrence of diseases, so we should do a good job in epidemic prevention and eradication. The enclosure is disinfected regularly and vitamins are properly added to the feed.

C. Feeding and management of nutria during the breeding period:

The feed nutrition of maternal rats in the third trimester of pregnancy must be at full price to meet the needs of normal fetal development and postpartum lactation. This period, such as undernutrition all caused by 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 weigh only 0.15 to 0.25 kilograms at birth, have all their teeth at birth, and will eat and play in the water a few hours later. The offspring developed rapidly, reaching 0.35-0.38 kg at 10 days old, 0.42-0.43 kg at 20 days old, 0.6-0.65 kg at 30 days old and 0.9-1.0 kg at 40 days old. This period of growth requires more inorganic elements and a lot of protein, a variety of 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.
