Focus on the selection of breeding geese The geese were screened in four stages: The first stage was to select the hatchlings from the 2 to 3 year old geese that hatched on time, with strong physique, good villous luster, and soft abdomen. As a breeding gosling. The second stage: Around the age of 70 days, the fast-growing, feathers meet the breed standards and good quality as a reserve goose. The third stage: From 130 days old to pre-opening, the goslings are required to be large in size, good in constitution, well-balanced development of various organs, males, flexible eyes, long, blunt, tight, and strong necks. (The liver is short and thick with a goose neck), the chest is deep and wide, the back is wide and long, the abdomen is flat, the scorpion is long and thick and strong, the distance between the two jaws is wide, and the sound is loud and loud. The goose requires large and heavy body, feathers clinging closely, bright luster, flexible eyes, long and narrow neck, long and round body, narrower forequarters, deep and wide hindquarters, wide buttocks, firm legs and wide distance. The fourth stage: Choosing goslings with multiple production, long duration, large egg production, large size, and timely production will be reserved for breeding geese. This method will be carried out after the first egg production period. Planning production according to the growth and production rules of breeding geese The useful life of the geese is determined according to the actual production performance of the breeding geese. The general breeding period is 5 to 6 years, and the age is 4 years. The energy is strong and the breeding power is strong. The mating behavior of the geese is different from that of chickens and ducks. Many male geese have annoying reaction to the mother geese they lived in, but they are very intimate and affectionate to the nearby mother geese. When mating, the old mother goose can be used with male geese of about 1 year old age. The new female goose is allocated with male geese of 1 year to 2 years old. The geese of about 1 year old should be male geese should be 1 month to 2 months longer than female geese. Pay attention that when breeding a male goose, do not allow it to be bred so as not to reduce fertilization rate. Goose laying has a certain law. During the year, the mother geese started to lay eggs in September in the late summer and early fall, and stopped production around April in the following spring. The laying period was about 8 months. The goslings enter the moulting period of about 4 months after production is stopped. After the moult was finished, the body condition gradually recovered and it was ready to re-lay eggs. Due to the inconsistent egg production ability of each breeding goose, the strength of nesting is also inconsistent. Individual mother geese have poor nesting traits. If they can find such individuals, they are very good for breeding breeding geese. Staged feeding management Gosling rearing The goslings are delicate and have poor ability to adapt to the external environment. They must be carefully managed and kept scientifically. The brooding room should maintain the proper temperature, not lower than 28°C in the first week, and 1°C～2°C lower in the week. When goslings can walk independently within 24 hours of hatching, the goslings should start drinking water in a timely manner, but they must do “first drink water and then start eating.†Drinking water for goslings must be clean and the temperature is appropriate (around 20°C). Drinking 5% white sugar water on the first day can increase the survival rate of the goslings. The feed for startling goslings can be mixed with 2 finely chopped grass or leaves plus 1 broken rice (soft rice, corn, or 70% to 8 ripe rice can be minced) and then mixed well. The feed is sprinkled on a shallow dish or plastic sheet for feeding goslings. 50% to 10 days of age can use 20% to 30% of rice or mixed concentrate plus 70% to 80% of grass or leaves, 2% to 3% of the flour, 0.5% of shell powder and 0.3% of salt From 11 days to 20 days, the ratio of fine material to green material is adjusted to 1:4 to 1:8; from 21 days to 30 days, it can be adjusted to 1:9 to 1:12. 1 day to 10 days Age 8 to 10 times a day, 11 to 30 days of age fed 5 to 6 times a day. The goslings of the goslings have short digestive tracts, and they have fast growth and development, and they must feed “night food†at night. Normally, two nights food is fed before 15 days of age, and one night's food is added after 15 days of age. After one week of age, goslings can be selected for short-distance grazing after warm and windy weather. The grazing time is divided into two times, which are arranged in the morning and afternoon respectively. The time for each grazing should not be too long. It should be controlled for about half an hour to 1 hour. After that, the grazing time should be extended as the age increases. Rainy days should stop grazing. Feeding of goose Goslings are raised to about one month of age and enter the middle goose stage. The goose's digestive organs are well-developed and their digestive capacity is enhanced, and grazing should be the mainstay. At the time of grazing, it is appropriate to use 200 to 300 individuals. If the geese are too large, the geese will easily feed on the ground and affect the uniformity of the geese. When grazing, goose should be slowly eaten, chaos can not chase chase, prevent trampling and fall injury and poor feeding. Grazing time is about 9 hours a day, 5 hours to 6 hours, and 3 hours to 4 hours. Hot summer weather, direct sunlight at noon, not grazing all day long. The animals usually graze in the early morning and they graze at around 10 o'clock in the morning and feed at noon. After 15 o'clock in the afternoon, they graze and graze in the evening. Where water is available, reasonable arrangements should be made for drinking time. Each time the geese should be full, they should be allowed to drink. Generally let the goose drink to the esophagus to expand below the throat to drink, it is best to drink 2 times a day in the morning, drink 3 times in the afternoon. About half an hour each time drinking water, go to rest after landing 30 seconds to 60 seconds to continue grazing. The growth and development of Chinese geese is fast, and the appetite is strong. If there is a shortage of pasture resources, they should be properly fed with grass or mixed concentrates. Mixing concentrates mainly include corn and soybean meal, and then add appropriate amounts of bone meal, salt, and mineral additives. Breeding of geese In winter and in the period of maternity and fecundity, the geese should be given high-quality blue-green materials, and the fine materials can be properly supplemented. In general, the geese diet was switched to feed 4 weeks before egg production, and the crude protein level of feed was between 16% and 17%. During the entire breeding period, each geese was fed 250g to 300g of mixed powder each day according to body weight, and sufficient quality roughage was supplied throughout the day. The geese more than 2 years old are mainly based on grazing coarse material, and appropriate supplements of a small amount of fine material. The goslings prefer to fight and the grouping is best done before the breeding season so as to avoid riots caused by temporary group formation and affect the fertilization rate of the geese. Grasping the Management of Production Period and Raising Fertility of Breeding Geese Proportion of male and female mating The general large-scale goose male-male ratio is 1:3 to 1:4, medium 1:4 to 1:5 and small 1:6 to 1:8. Some species of male and female goose have very different physiques, they are difficult to mating naturally, and their fertilization rate is low. Artificially assisted breeding can be used. The conditional breeding goose farm can be bred by artificial insemination, which can increase the fertilization rate and feed reward of the breeding eggs. Reasonably supplement lighting The general illumination time is 13 hours to 14 hours. The light intensity of 25 lux per square meter can meet the egg production and breeding needs of the goose. Properly extending the light time to 14 hours to 16 hours can extend the egg production of geese, increase egg production, increase the number of eggs planted throughout the year, and increase egg utilization. Feed nutrition Breeding geese must provide a full-fledged, full-priced diet. Each kilogram of concentrate contains 11.34 MJ metabolomic energy ~ 11.76 MJ, crude protein 16% ~ 17%, calcium, phosphorus ratio of 2.5:1 ~ 3:1. The diet should be dominated by high quality green and juicy feeds and mixed concentrates, supplemented with vitamins and mineral feeds. Scientific breeding Goose is a grass-fed waterfowl that has a higher fertilization rate in the morning than on land. Therefore, the ideal water for grazing is clean water with a depth of 0.7 to 1.0 meters. General geese naturally mated at a ratio of 1 male to 6 females, which results in higher fertility rates. If the egg fertilization rate of several gooses is found to be low, it may be due to a problem with a male goose that is mated with them. The egg should be removed promptly; for example, the egg fertilization rate of individual female gooses may be mismatched and should be artificially assisted. Method breeding. Manual supplementation should be carried out shortly after laying. At this time, the sperm easily runs in the fallopian tubes, which helps to increase the fertilization rate. Grasp the prevention and control of breeding geese Gosling plague is a major infectious disease that harms geese. During the prevention, the gosling plague vaccine can be injected intramuscularly 30 days before the breeding geese start production. The produced eggs can obtain maternal antibodies, which can make the goslings produce passive immunity and avoid goslings. For goslings that have not been injected with gosling plague vaccine prior to the start of production, goslings incubated with their hatching goslings should be injected with anti-goat larvae immediately after hatching, and then vaccinated once a day after 10 days of age. , for lifetime immunity. Fowl cholera is an acute septic-type infectious disease of poultry, especially for waterfowl. 0.3% oxytetracycline powder was added to the feed for 3 days to 5 days once a month. Vaccine against cholera can also be used for vaccination. In addition, under the current severe epidemic situation, the epidemic prevention of highly pathogenic avian influenza should be strengthened. The first immunization was performed with H5 recombinant seedlings at 14 days of age, followed by a second immunization after 3 weeks, followed by booster immunization every 4 months.
