Hydra breeding and management technology
1 Preparation for breeding period
Seize the time (from the end of December to the beginning of January) to inject dog fever and infectious enteritis vaccines, and strictly check the phlegm of the species to strengthen the way of exercise and reduce the accumulation of fat. In particular, public money, to develop the habit of playing; to maintain 7-8 percent (body mass index of 24 to 26 is appropriate). In the breeding period, garlic, green onions, carrots, and aphrodisiacs can be added to the feed.
2 breeding period
The exact time is from mid-February to mid-March, during which the nutritional requirements for quail feed are comprehensive. The breeding period of the male cricket is short, and lean meat and eggs are added to feed to supplement amino acids. In recent years, four months after the end of the breeding season, the breeding stalls were sold and the breeding ground began to raise only females.
3 pregnancy
Pregnancy, also known as gestation, requires careful management. Feed anti-mold, anti-intoxication; anti-hormonal tires, anti-startle, anti-abortion, anti-chemical tire space Huanyu, in the feed to add fetal drugs ve and progesterone.
4 calving
The quail enters mid-April and it is also called littering. The litter and lactation periods are the most difficult times to manage and the highest mortality rates for raising fish. In the past few years, the litter size is much more productive and less alive. The number of calves per calf is very different. There are 12 females, 1 male, and 4 males. The average yield is 6-8. The mortality rate is high, especially the mortality rate is 50% less than 2 weeks postpartum, and the mortality rate reaches 73%. The average production of 3 does not make money, but can only maintain the original; the average production of more than 4 profitable. To achieve this goal, many farmers use milk powder, soy milk, eggs for feeding and mother-fed eggs.
5 minutes
By the end of June, Aberdeen can feed on its own feed. The body weight of nearly 0.5kg (40 to 45 months of age) can be used to wean the litters: feeding into the breeding and management period. The management of the nesting period affects the survival rate, and the secondary and tertiary nesting methods (according to the development status of Aberdeen, the size of the batch weaning) can increase the survival rate by 20%.
6 epidemic prevention
In early July, dog fever and infectious enteritis vaccines were injected to prevent the occurrence of infectious diseases.
7 selection
The young cubs were matured in September, and they were able to select the species with a weight of 1.5-2.0 kg (for primaries). The mother-in-law selects excellent individuals who have good motherhood, sufficient milk, and high survival rate of their litters. The male-female male and female are exchanged at the outfield and the farther apart the better. The number of primaries retained is 30% more than the actual number selected, and the individuals who will remain seeded will be re-entered from September to October. The sturgeons are kept separately; the sturgeons, which are not used for breeding, increase the supply of fat and sour amino acid feeds, promote the hair exchange, and increase the skin length. The quality of pods is related to the conception rate, birth rate, and survival rate, and the three rates directly affect the economic benefits of production in the following year. Individuals with good and inferior varieties can have one grade of skin loss, and one grade with less income. Tens of dollars. The current varieties are Jinzhou black, U.S. short black, Jiaozhou black, and red-eye white. The majority of them are breeding black storks. There are very few pheasants, and the price of enamel is 20% higher than black storks. The most important criteria for species use is that the body weight of the male fleas should be more than 2kg and not more than 2.5kg; the weight of the female cub should be 1.2kg or more and not more than 2kg. Body length: Male nose is more than 45cm from the tip of the nose to the tail, and 38cm above the body. Health-free disease: The head and eyes are flexible, playful, eating and drinking water is normal, there is no disability, reproductive organs are not deformed, there is no history of illness, no food, and tail bite. Reproductive ability: The number of maternal calves is more than 6 and the maternal property is good; the ability of breeding female males is more than 10 times. Can not reach the body length standard, can not be used for breeding at night; used hormones should not be left to plant; summer hair is not returned to the whole can not be used as a species, the head body is abnormal, there is biting tail, eating hair disease is not optional For species use. Seed selection should also carefully investigate the pedigree of the introduced species to avoid close relatives.
8 skins feeding
8.1 Injection hormone
The injection of melatonin is known as hormone glycosides. Since cooked skin is kept early and the skin is harvested, it can be sold 50-65 days in advance, which can save feed expenses by 10-15 yuan per person. The quail feeds the winter hair growth period during the period of burying hormones.
8.2 Natural Mature Leather
In the case of skinflies, feeds containing fat and sulphur-containing amino acids are used in the feed. Pigs can be used to make oil, chicken intestine and various meats, fish, etc. to promote the rate of hair replacement. In 3 months, they can be skinned. From November to early December, it is time to collect hides.
