Scientific breeding of mackerel needs to be done well.

Roe deer is a precious ruminant herbivore of the deer family, commonly known as grass flying, is a game delicacy in feudal society. After the founding of the people's Republic of China, it was a foreign exchange earning product for foreign trade acquisition and export. In the late 1970s, due to the neglect of the protection of wild roe deer resources, the number of roe deer decreased sharply in China. In order to save the resources of roe deer and expand the number of roe deer in China, Chinese scientists have carried out artificial domestication and breeding techniques of wild roe deer and achieved success. Now the experience of artificial raising roe deer is introduced to the broad masses of readers for reference only.

Seed selection pass

The selection and purchase of an excellent species of roe deer is the mother of success in raising roe deer. In recent years, because many new breeders do not understand the basic knowledge and quality standards of raising roe deer, they buy roe deer at a low price from some farmers, resulting in heavy losses. For example, Ji Chunsheng in Wuchang City, Heilongjiang Province spent 130000 yuan to buy 34 roe deer, 3 died on the way, and was fined 5000 yuan on the way because of incomplete breeding procedures. When he got home, he found that half of them were unqualified, and he lost a lot of money because he had not been in estrus for two years. Because of the high price of high-quality roe deer, two farmers in Nanguan, Fengning County, Hebei Province privately bought back more than 10 unqualified thin roe deer. As a result, all of them died after 4 months at home, with a loss of more than 20,000 yuan. In order to avoid the lesson of the past, it is important to keep in mind when choosing roe deer:

1. Must be introduced to qualified farmers, it is best to investigate first, to understand the basic knowledge of raising roe deer and species of roe deer standards. two。 The criteria for seed selection should be carefully mastered: the individual is medium, energetic, responsive, straight foreleg, hindleg arch, smooth hair film, moderate body mass, no disease and no disability. The best age is the breeding of roe deer from 5 months to 6 months of age in the same year. The best way to buy roe deer is to give birth to 1 ~ 4 babies (16 babies). 3. Do not buy roe deer species cheaply from second-tier dealers. 4. The male-female ratio of buying roe deer is 1 male and 2 female, or it can be purchased in pairs. As the female roe deer only once a year and estrus time is concentrated, so male dogs should not be too few, in case individual male roe deer can not be used in rotation due to poor performance due to feeding and other reasons. When buying and breeding male and female roe deer, it is best to match a small amount of male roe deer aged from 2 to 3 years old.

Adaptive pass

It is also the basis of success to put the introduction into the circle and feed the management and adaptation. Species of roe deer from capture into the cage, transportation to the new home breeding life, because it is a new person, the new environment, the newly purchased species of roe deer is difficult to adapt. Therefore, it must be carefully managed to make the roe deer adapt to the new living environment as soon as possible.

1. Suitable enclosures should be built before seed purchase. two。 Before planting roe deer in the house, one day and night of forage (mainly leaves, with appropriate amount of corn flour and wheat bran) and clean drinking water should be prepared in advance, so that roe deer can not be disturbed and familiar with the environment. Generally, after one day and night, roe deer can adapt to the new environment. 3. At the initial stage of introduction, special people should be set up to keep the roe deer from being frightened, forbidding strangers to visit. 4. In the initial stage of entering the circle, attention should be paid to prevent roe deer from diarrhea caused by disobedience of soil and water and improper feeding. It was gradually transferred to normal feeding after about 10 days. The roe deer feed is mainly composed of broad-leaved leaves such as poplar, willow, tussah, birch, elm, apricot, fruit and locust (branches replace leaves or oars in summer, and dry leaves are collected after autumn for consumption in winter and spring), each of which is about 600 grams per day. Add about 300 grams of mixed concentrate: 150 grams of corn flour, 75 grams of wheat bran, 75 grams of sunflower cake or bean cake, 50 grams of sorghum flour, fed three times.

Feeding pass

Roe deer is raised by people, and success lies in people's feeding. Feed with full nutrition is the foundation of the success of raising roe deer.

1. On the basis of introduction into the circle to adapt to feeding, based on the actual physique and fat condition of roe deer, a small amount of mixed coarse and concentrate feed was increased and decreased. According to the number of leaves in the rural mountain field, mainly a variety of broad-leaved leaves, conditional supply of non-toxic green pepper, eggplant seedlings, sunflower plates, green beans, forage grass, sesame, peanuts, sweet potato seedlings, etc., and supplement the mixed concentrate. two。 The roughage of Laozi is mainly composed of leaves, and it can also process coarse grass powder or autumn cut grain grass, bean straw, bean husk, sunflower stalk, corn straw, etc., with a dosage of 40%. Add 25% corn flour, 15% wheat bran, 15% soybean cake or sunflower cake, 5% sorghum noodles and 10% sorghum noodles. Each adult roe deer is fed about 500 grams a day, about 150 grams each time, and mixed with water 20 minutes before feeding. Based on the principle of eating, crawling, lying and regurgitating, and having a small amount of surplus material. At ordinary times, we should pay attention to keep the trough clean and add less water to prevent freezing in winter. 3. In order to adapt to the night-eating habits of roe deer, an appropriate amount of leaves should be added every night, and fresh-cut firewood and branches can be added in winter and spring to keep them fat and strong. 4. Keep clean drinking water in the enclosure so that roe deer can drink it at any time. In summer, clean and disinfect the bucket once a day, change the water at noon; supply water during the day in winter, collect the bucket to prevent freezing at night, and also put ice cubes to let it lick itself. 5. Roe deer and cattle, sheep and deer, also need to supplement minerals and salt, can buy deer lick brick hanging in the circle for roe deer to lick freely. 6. Pay attention to control the body condition, species roe deer should not be too fat, it is better to maintain normal fat condition, and individual weak roe deer should be fed separately.

Epidemic prevention pass

Although wild roe deer has strong disease resistance and rarely gets sick, domestic roe deer should also take comprehensive measures to prevent the occurrence of diseases.

1. Stop the disease from the mouth to the customs. Roe deer to eat forage, leaves, concentrate, etc., must be rotten, no residual poison, drinking water should be kept clean.

two。 The enclosure should be cleaned once or twice a day in spring, summer and autumn so as not to accumulate feces and urine. The mat of the lying place is dried and sterilized clean land. Do not sweep circles in winter to keep warm.
