Breeding management of geese
The geese from the start of production to the elimination period are called breeding geese, also known as adult geese. The purpose of feeding is to obtain a large number of good quality eggs. The characteristics of geese. Strong appetite, large appetite, especially the ability to eat grass, shells, snails and other strong. Therefore, we must ensure that the goose is fully fed, especially the supply of mineral feed, otherwise it will affect the production of eggs. Male geese fight well and have a strong sex drive. Before the advent of the geese, the ratio of male and female geese should be adjusted. The habit of laying eggs at a fixed place in the mother goose is very strong. Therefore, a production shed and an egg production nest should be prepared before opening. Goslings have nesting and should take measures to promote their nesting. The geese during the laying period are slow in action and should not be rushed during grazing. In addition, the foie gras has a strong fat deposition capacity and a strong down regeneration ability, which can be utilized to produce fatty liver and live pull production. Geese's egg production patterns. Egg production in geese has a marked seasonality and is usually the breeding season for geese in June. Because the goose's nesting ability is very strong, the eggs produced before the nest are called "wombs". After about 43 days per nest, 55 eggs are laid, and a second nest of eggs is laid in the nest for a month. Generally, 1 nest is produced each year. The egg production of the mother goose was the highest in the 12th year and was the lowest in the first year, which was equivalent to 65 in the third year. The second year was equivalent to 35% in the third year. The egg production decreased year after year in the fourth year. Goslings have different egg production times each day and generally lay eggs during the second half of the night until the morning. Due to the different breeds of geese, there is a big difference in the age of production and egg production. The small white geese in our country's geese have a production date of approximately one month, 355 eggs per year, and an egg weight of 36 grams. Large-scale geese have an opening date of about 3 months, 15 eggs per year, and an egg weight of 66 grams. Feeding management during different egg production periods. Because geese produce less eggs than chickens and ducks, the reproduction rate is low and they need to be used for many years. Therefore, egg laying geese can be divided into three stages in a biological egg production year, that is, the egg preparation period, the egg production period and the maternity period, and the different focuses of feeding and management at different stages. Egg preparation period. About 2 days or so in this period, the geese are required to properly increase their weight while removing a large number of new feathers, in preparation for laying eggs. In the rearing, according to the geese's physical condition, the change of new feathers and the change of temperature, timely feeding. Generally after the main wing feathers and aileron feathers have been exchanged, the proportion of fine material is increased. The fine material can reach 54 and three times every day and night. The male and female geese are best kept separately. The goose feed should be fed 36 weeks earlier than the female geese. This will allow the male geese to finish the moulting ahead of time, so that the geese will be physically strong and energetic before opening the breeding geese to facilitate breeding. In management, we must always keep clean drinking water, exercise properly, and grazing should come early and return early. The route should not be too long. The water release time can be extended appropriately. In addition, depending on the season, consider gradually increasing the light. Egg production period. After the geese are raised in the preparation period, their weight will increase and their physique will be enhanced. They will gradually enter the laying period. During the laying period, feeding should be based on feeding, supplemented by grazing. The proportion of dietary mix is ​​approximately cereal 654, cake 34, bran 3534, filler (grass) 3534, and mineral feed 24. In addition to the free feeding of green feed, each goose was fed with 35 grams per goose, 35 grams of small goose, and fed once a day. Feeding should be timed quantitatively, first after the coarse finish. Grazing in the morning until 35 o'clock, feeding, feeding in the shade of the water to rest, and voted for green material, feed once at 6 o'clock in the afternoon, after 1 o'clock grazing, feeding the evening after the third feed. After each feeding, the geese were allowed to put water to rest. In terms of management, the goose during slaughter operations is slow, and it is advisable to follow the gosling during grazing. Minimize slopes and uneven roads to prevent intra-abdominal and fallopian tube bleeding leading to peritonitis, etc.; collect eggs in a timely manner, and find that some geese have egg production performance when grazing, such as unwilling to follow groups, cry out loud, and feel disturbed. Nesting should be promptly rushed back to the house or held back to the goose shed for egg production. In particular, the mother geese should be carefully observed during the first stage of production to prevent the production of wild eggs and underwater eggs. The light time of the geese during the production of eggs should not be less than 31 hours per day, and 33 hours of light should be maintained during the peak period of egg production. In addition, to strengthen the management of nesting geese, when the mother goslings are nested, if they are not allowed to hatch, measures should be taken to make them wake up as soon as possible to restore production. Found that the mother geese should be isolated in the nest, put it into the no-mat grass, compared to the shady enclosure, stop feeding 61, but pay attention to enough water, 61 days later gradually fed only some cereals, sweet potatoes and other raw materials, promote It wakes up nest. In the meantime, cold water immersion method can be used to promote its nesting, that is, once a day and afternoon, the geese can be soaked in 65, the following cold water for half an hour. In addition can also use drugs to promote their nesting, aspirin 6 tablets a day, 3 tablets on the afternoon of the afternoon, or intramuscular injection of analgesic, Angipilin, once daily, 3 ml each time, or intramuscular injection of testosterone, once a day, 5-ml each time. In practice, the above measures should be comprehensively adopted according to the species, so as to urge the mother geese to wake up the nest in order to increase the egg production. In order to increase the fertilization rate of the eggs, the ratio of breeding should be 3.35 in addition to the nutritional requirements for breeding geese. In addition, there should be an ideal source of water, a moderately sized aquatic playground. Every hundred geese should have 2,565 square meters of water sports grounds. Male geese are good at fighting, especially in the morning and evening breeding, they should promptly drive away in order to avoid male goose injuries. Male geese have a useful life of one year and should be eliminated every year to supplement the new goose. 1 stop production period. Female geese produce eggs until about January each year. Egg production decreases, egg weight decreases, and misshapen eggs increase. At this time, most goose feathers are dry and some appear to be anemic. The male goose plucked forward and the fertilization rate of the egg decreased. About the end of the month, egg production enters the rest period, and the egg production can be resumed in the month. In this period, the following tasks should be focused on. 26 groups. Make a selection of geese, select the best ones, and supplement new breeds of goose proportionately. The breeding geese within three years can be eliminated, and only the disease, residue, egg production is very small, the reproduction rate is low. The group of geese can be divided according to a certain age, with 5 years old geese occupying 34, 3 years old geese 31, 3 years old goose 34, 6 years old gooses 512, and over 1 year old gooses occupy 54; that is, the annual elimination rate is 12; The number of geese supplemented by the reserve, this can ensure the normal production of breeding geese. Professional goose farms should also be reared by age. Change the feeding method. The selected breeding geese will change the feed from the concentrate to the coarse material, and gradually stop supplementation, and implement extensive feeding based on grazing. Extensive feeding can promote the exchange of feathers, help to control the mother goose without excessive fat, but also can cultivate the coarse tolerance of the geese, but also reduce the cost of feeding. 6 kinds of geese forced moult. The goose during the rest period can be forced to moult, so that the geese can resume egg production at a more uniform time, and it can also shorten the moulting time. The forced moulting of the geese is to change the feeding and management conditions to promote the feathers to dry off and to match the artificial pullout. When the goose goes to rest, the male and female geese are separated and the feeding amount is reduced from once a day to a second, or once every other day, and then gradually to 3 days. After about 5 days, the goose body is gradually thin and the body weight is reduced by 5 About 3/3, the dryness of the main wing feathers and the main tail feathers can be artificially drawn. When pulling the plume manually, hold the two wings of the goose by hand, lift it up, separate the wing feathers with the other hand, and pinch the five wing feathers with your thumb, forefinger, and middle finger, and pull them out in the direction of growth. The pullout order is the first main wing feather, the rear wing feather, and the last tail feather. When artificial plucking occurs, if the root is not completely dry, the blood should be pulled when pulling; the plucking is only to remove large feathers; the plucking should be performed in warm weather, and should not be carried out in cold or rainy days; the geese with weak constitution cannot Pulling feathers; for individual main wing feathers have been newly grown (early production stopped, natural moulting) can not pull out. After artificially pulling the plume, feeding can be gradually resumed and feeding management can be strengthened. China Agricultural Network Editor
