Breeding Techniques of Special Wusuli Bream

Ussuri is a wild economic animal with a high economic value. It is famous for its rich plush and good insulation properties. Pork is a rare and nutritious game food; gallbladder and testis are valuable Chinese herbal medicines; and wolfberry fat is a raw material for advanced cosmetics. It can be said that the body is a treasure and its use is very extensive. In recent years, due to people's killing, coupled with their low fertility in the wild, the number of earthworms is on the verge of extinction. Therefore, the artificial breeding of earthworms is actively carried out, which is conducive to the protection of wildlife resources and to the enrichment of the people. The main points of breeding techniques are described below.


First, the choice of excellent species

1. Selection of quality traits. The quality traits (such as coat color, etc.) of quail should be selected on the basis of the phenotype of the individual. Colors tend to be yellow and red, and brewing is more beautiful.
2. The choice of quantitative traits. Quantitative traits of quail (such as body length requirement between 65 cm and 80 cm, hair length of about 6 cm, plush density for the rotation of the body gap is better, the nipple in more than 4 pairs), so that in the breeding of quail Obvious results.

3. The method of choice. For juvenile clams, according to the birth date of each litter, the number of juvenile clams (the body weight can be weighed and the length of the body are compared with the population's body weight and the average length of the body). The male is born before mid-April, and the female must be born. Born at the beginning of May), normal development, early blinking, and clear lineage retention.

Second, the good feed off

1. To feed cooked food. Cornmeal 50%, bran 20%, bean flour 10%, fishmeal (small fish, shrimp or slaughtered leftovers can be substituted) 15%, the above types are mixed to make a paste, then add 5% of the vegetables, now produced Now feed about 400 to 700 grams per day.

2. Pregnancy and farrowing stages. At this time, it is necessary to appropriately increase animal feeds with high protein content. Crude protein can account for 25% to 30% of the total energy of the diet at this time.

Third, the good feeding and management Guanyu puerpera feeding and management period (from early May to late June) should be feeding adult quail diet, feeding 2 times a day, bred pupa (July to October) dietary animal feed accounted for 10 % to 15%, 300 grams per feeding, 2 times a day, to ensure adequate drinking water.

IV. Rearing and management of adult clams

1. Prepare the breeding period. In the early period of breeding (October-November), the principle of dietary supplementation, the proportion of animal feed is not less than 10%, and fat-containing feedstuffs can be appropriately increased, and the feeds are fed once a day in November, and the body weight is 5-7. Kilograms, 6 to 8 kilograms for males; ready for breeding late (December-January-January) to balance the body condition, over-fertilizer to reduce sputum, weight loss measures is to halve the diet.

2. Breeding period (from early March to early March). To provide publicly-funded diets with nutritious food, animal feeds can be fed to some eggs, and the estrus status of the mothers can be checked every day or every two days to facilitate timely breeding. 30 minutes before and after feeding.

3. Littering and lactation (from early April to early May). Safeguarding live calving, promoting the development of Aberdeen, ensuring that the mother's bedding is adequately milky, supplementing milk or soy milk with dietary supplements, fine-grained feed processing, thinning mixed feeds, satisfying supply, and adequate drinking water every day.

Fifth, disease prevention and treatment are the main methods, supplemented by treatment, and prevention is more important than treatment. This is the most effective measure to make rickets less sick.

In general, crickets have strong resistance to disease. During the breeding period, regular cleaning and disinfection are sufficient. For several common diseases, such as: the occurrence of a cold, the treatment of oral oxytetracycline 80,000 international units, or according to the amount of 1/4 to 1/3 oral compound sulfamethoxazole. Gastroenteritis (diarrhea) Add a small amount of oxytetracycline and furazolidone (at a dose of 30 mg/kg body weight) to the diet and feed twice daily.
