Science breeding goose

1. Eliminate high-yielding breeds of geese (1) Strictly eliminate outdated growth and development in about 40 days before opening, abnormal body shape, poor physique, thin or overweight, disease, sarcoma, tendon, lice, and feather color Individuals of this breed characterize. For the male goose to check the development of the penis, choose to leave the penis out of the cloacal 3-4 cm long, erection is good, good quality and quantity of semen, out of the penis is not easy to stick out, short and thick or deformed individuals. The female geese must choose to stay strong, have strong appetite, normal posture, and body-waisted barrel-shaped bodies, and are willing to accept individuals breeding male geese. (2) Elimination of low-yielding geese Because the reproduction rate of geese is relatively low, and the egg production rate is lower in the first year and higher in the second and third years, it declines only in the fourth year. Therefore, do not put the first and second products. All female geese in the egg year are eliminated. It should be the geese who produce fewer eggs, have a small egg weight, have strong broodiness, and do not receive goose breeding or over-fertilization or prematurely stop moulting or sickness. Poultry geese with low breeding ability are eliminated. In this way, the production performance of breeding geese and their offspring will become better and better. When updating the geese population, the male and female geese must be exchanged according to the proportion of males and females. Otherwise, the fertilization rate of the breeding eggs will be affected. 2. Scientific rearing (1) Nutritional level The dietary nutrition level of the goose during the egg laying period should be 14%-17% of crude protein, 11.3-12.5 MJ/kg of metabolizable energy, 3%-3.2% of calcium, and 0.45% of available phosphorus. - 0.5% and appropriate amount of vitamins, trace elements, each geese feeding amount of 150-250 grams per day, high quality fresh pasture 500 grams. If a variety of high-quality forage grass such as multi-flower ryegrass, winter grazing mix feeding chicory, grain wolfberry, bitter vegetables, grass and other 2-3 species of grass mixed feed, the effect will be better. (2) The feeding should be fed regularly 2-3 times a day, plus 1 feeding before and after 10 o'clock in the evening, which has a significant effect on increasing egg production. (3) Sufficient supply of clean drinking water without interruption is a material guarantee for the promotion of high yields. It is best to use regular fresh drinking water. (4) The combined diets during the egg production period begin to feed 3 weeks before the breeding geese start production, which can effectively promote follicular development and prolific egg production. 3. Appropriate environment (1) The location of the goose farm has a particular emphasis on the kind of goose farm should be built in a secluded place away from towns, villages, traffic arteries, no pollution, no strong vibration, complete water and electricity facilities, drainage system is intact, easy Keep dry, reasonable layout, easy management and safe production. (2) Reasonable construction design of goose house Huanghuai Plain and its north area should be built north-south single-row type goose house, which is a single-room single fence open architecture. The height of the goose house is low in front, the front slope is short, and the back slope is long. The front elevation is about 1.8 meters high, the rear elevation is about 1.5 meters high, the fence is about 60 centimeters high, and the concrete is mixed with a single brick. Stitched into. Each area of ​​the shed is 310 = 30 square meters (ie, the shed, the land sports field, and the water sports field are connected into a whole). A slope with a 0.5% internal high outsole at the interior to the water sports grounds facilitates drainage to keep it dry. 4. Careful management (1) Reasonable grouping According to different breeds and ages, the animals should be reared strictly in groups, and 15-20 should be kept in each unit to prevent mixed groups. (2) Reasonable proportion of male and female small geese 1:5-6, medium-sized geese 1:4-5, and large geese 1:3-4. It is also necessary to make timely adjustments based on the production rate of the mother geese and the fertilization rate of the breeding eggs. In the middle and late stages of egg production, the male and female geese with low performance are eliminated in time, and the male and female geese are put into the reserve male geese according to the ratio of reasonable male and female to increase the fertilization rate of the breeding eggs. (3) From 22 weeks of age to 30 days before the start of production, natural lighting time and intensity should be used. From the 30th day before opening to the start of production, the natural lighting time should be gradually increased to 15 hours (approximately 1.5 hours per week). Keep the whole egg production period for 16 hours. Light intensity is generally a 40-watt ordinary bulb per 12-15 square meters, and the lamp is 2 meters high. (4) The suitable temperature and humidity suitable for breeding geese eggs is 5°C-25°C and the humidity is 60%-75%. Therefore, in the winter, we must do a good job of preventing cold and warming, prevent the low temperature from increasing the nutritional needs of the goose body, reduce the egg production rate, and even stop the production of wool, resulting in low yields throughout the entire process. Take measures to increase the cold weather covering on the goose roof, block the ventilation holes and the windows on the north side, narrow the open area of ​​the doors and windows, change frequently and increase the amount of bedding in the room, during the cold wave, cover the front window with transparent plastic film and other measures. After mid-May, we must do a good job in the prevention of heatstroke and late-stage egg management. We must appropriately increase the protein content of the diet, reduce the amount of metabolic energy and roughage, and increase the fresh green feed and VE and VC levels. Open all the doors and windows of the goose house and the ventilation holes. Construct a cool shelter on the playground to prevent the temperature of the house from exceeding 30°C. (5) Strictly prevent the harm of stress Goose is shocked and frightened. It is sensitive to all kinds of environmental stress factors, such as abrupt climate changes, changes in feeding and management equipment, blackouts, changes in the light system, sudden feed changes, insufficient drinking water, or Lack of rations, irrational architectural design of geese, inability of feeding and management equipment, transfer to groups, immunization of vaccines, brutal geese, geese, sudden loud yelling, sudden shocks, irregular feeding, stranger and animal access Such stress factors will reduce the geese feed intake, feed conversion rate, and production performance. In particular, the geese respond to various stress factors during the production of eggs and are relatively strong, and it is easy to cause loss of production, production and diseases. (6) Adjust the breeder's laying cycle. In order to meet the market demand and the temperature characteristics of the Huanghuai Plain region, the breeding goose seedlings and brooding period are arranged from December to January. From August to September, the production can be successively started. The production will be stopped until May of next year, and the high temperature in June-August. Seasonal production, in September began production again. During the period of production suspension, artificial living should be used to pull down feathers, which can increase the income and make the hair replacement period the same. (7) Making records In order to breed good geese, records should be carefully prepared. Firstly, the number of single-round broilers is numbered, and then the geese are numbered and put into the goose ring. The opening date, the daily egg production amount are recorded in units of a circle, and the circle number and egg production date are recorded on the egg shell. Samples were weighed and egg weights were recorded. Fertilization rates and hatching rates were recorded after hatching. 5. Ensure the safety of scales Goose must be cleaned, sanitized, quarantined, disinfected and prevented from epidemic prevention to ensure production safety. Based on local conditions, develop a reasonable immunization program and implement it carefully. For example, the standby geese pay attention to the fowl cholera and egg bacillus seedlings, and injected the gosling plague vaccine 30 days before the start of production to drive off parasites. If you are feeding aquatic grasses during the production of eggs, regular insecticides are also required. The area and geese must always be kept clean, hygienic, dry and regularly sterilized. When the outbreaks are found in and around the site, strict isolation and repeated disinfection are required to strictly seal the locks. It is strictly forbidden for personnel to enter and leave the place. Gooses and their pollutants that have died of an epidemic must be incinerated or sterilized at fixed points.
