1 Strengthening the selection of breeding geese
The selection of breeding geese is crucial for raising the economic benefits of breeding geese. Goose breeding households usually start from June to July each year and choose to keep geese from the geese hatched in March. At this time, the goose has not yet fully matured, and should be selected again in November. The feathers should be kept tight, compact, large in size, and healthy reserve goose left for species use. Male goose should be burly, with long neck and mouth, full of energy. Goslings with male geese that have genital insufficiency, penile malformations, and inability to establish sexual reflexes cannot be reserved for breeding purposes. Should choose to keep the penis well developed, can establish sexual reflexes, semen quality excellent goose retention. The goose should choose to keep the goose with short neck, short legs, and square back shape and choose to stay according to the standard weight of its species, eliminating gooses with poor growth and small size. For example, the weight of Taihu geese has a significant correlation with the number of eggs laid and the weight of eggs, and the number of breeding geese can be increased by selecting the major breeding geese.
2 Improved breeding methods
Before the laying of the geese, male geese were put into the geese at a male to female ratio of 1:6. Using the method of natural mating, the male geese often fight each other during the breeding process due to the fact that they competed with the female geese. Some geese caused penis damage during the battle and lost their breeding ability. Therefore, the geese must be bred every month during the breeding period. The penis should be checked once and the penis should be eliminated in time. In terms of breeding methods, breeding geese of small breeds should be naturally mated to artificially assisted mating. Goslings should be bred once every 5 to 6 days, and the proportion of males and females used for artificially assisted mating should be 1:10 to 1:15. Large-scale geese should adopt artificial insemination, using back-to-back massage and sperm extraction and direct insertion and insemination. This method is easy to grasp and has little investment. On the nest mother goose can use testosterone propionate to promote waking, by controlling the intake and drinking water so that it can quickly restore production.
3 Feeding full-priced compound feed
Goose farmers are affected by the habit of traditional breeding goslings. Feeding breeding geese is still based on grazing, and feeding a single feed during the production period is mainly rice. Relative shortage of grass resources in winter, grazing plus supplemental rice can not meet the nutritional needs of breeder geese and egg production. Breeding geese in the production of eggs use the body's stored nutrition, resulting in thin geese constitution, soft shell eggs, sand shell eggs increased. If we use full-price compound feeds to meet the nutritional requirements of breeding gooses, the potential for breeding geese will be fully realized. The nutritional content of the full price feed was: 2.65 Mcal/kg feed, 15% crude protein, 2.25% calcium, 0.34% available phosphorus, 0.7% lysine, 0.32% methionine, and 0.2% salt. Gooses are herbivores and have a large gastrointestinal volume. To ensure a certain volume of feed when formulating feed, the content of crude fiber can be controlled at 10%. The amount of compound feed should be determined according to daily grazing conditions, body weight, and egg production. Each feed should be supplemented with about 200-250 grams per day. Tests have shown that geese fed batches can increase egg production by more than 25% compared to geese fed a single feed.
4 Do a good job of grazing management
The geese should be built on the edge of a river bank rich in grass resources, and lay a shed before laying eggs to train the geese to develop the habit of laying eggs in the shed. When geese are grazing, “grass ponds in winter and ponds in spring†should be adopted. Through grazing, not only the geese can strengthen their movements, but they can also increase their physique, and they can save some concentrated feed by eating a certain amount of green fodder. Gooses should go out and grazing after laying eggs every day, and going out and grazing prematurely will cause the mother geese to lay eggs in the wild and affect the collection of eggs. The grazing should be ended before dark and the geese will be driven back to the geese. Egg laying geese are slow in movement and should be slowly driven away, especially if the downhill slope is slow. Grazing should be stopped in rain and snow days to avoid stress and affect the production of laying hens.
5 Increase lighting time
According to the needs of hatching and breeding goose families, breeding geese are generally controlled to start production at the end of December, when the natural lighting time is short, and the length of sunshine is only 10 hours, which affects the production of breeding geese. Therefore, from the start of the goose seeing the eggs, the light should be supplemented every morning and evening, and the light time is increased by half an hour every week until it increases to 15 hours. By increasing the light intake, more than 10% of egg production can be increased compared to a single natural light geese population.
6 Strengthen disease prevention
At present, geese, gosling plagues and parasitic diseases are the most harmful to gooses. From the end of November to the beginning of December, about 1 month before the goose lays its eggs, 50 mg of albendazole is given orally to each geese to remove the parasites. Oral cholera vaccine was given 7 days after deworming and vaccination against gosling was administered. Through vaccination, not only the breeder geese can resist fowl cholera and goslings during the laying period, but also hatchling goose geese produce antibodies against the gosling plague virus. Two-tenths of terramycin powder is added to the feed every two weeks for a half-monthly period to prevent bacterial diseases. For every kind of geese, egg sheds and surrounding sites, one disinfection is performed every week with 100 toxins and other disinfecting drugs. Usually, we must constantly observe the breeding geese and timely understand the dynamics of the geese. Once the disease occurs, we should immediately ask the veterinary department to confirm the diagnosis and take appropriate preventive and control measures to effectively control and treat the disease and ensure the health of the breeding geese.
Shiitake is closely related to Ganoderma. Shiitake is Japan's largest agricultural export product, and it is now the most popular and cultivated exotic mushroom in the world. In China, the history of shiitake mushrooms can be traced back to the Ming Dynasty (1368-1644 AD). Shiitake is used not only as a food, but also as a medicine for treating upper respiratory tract diseases, poor blood circulation, liver diseases, fatigue and weakness, as well as promoting Qi or vital energy. It is also thought to prevent premature aging.
