Key points of management techniques for egg-laying geese

The key point in the management of geese entering the laying period is to develop good living habits in order to improve reproductive performance, lay a good production foundation and ensure the production of many and good goslings.

Choose the best and look for the bad of geese before laying eggs

For breeding geese (reserve breeding geese), those female geese with moderate body weight, moderate body shape, appearance and coat color that meet the requirements of this breed and start giving birth at the right time (200 ~ 240 days old) should be selected. For breeding geese, it is necessary to refer to the previous egg laying records and choose female geese with more eggs, moderate egg weight (more than 130 grams), normal egg shape and shell color and no (or weak) clasping. Male geese require normal penile development and strong males. About 30 days before the start of production, the geese were injected with Gosling plague, paramyxovirus disease and Gosling new viral enteritis vaccine. It is necessary to group geese reasonably. Each flock should have a ratio of 60 birds to 100 males and maintain an appropriate male-to-female ratio: medium geese 1, 4 × 1, 5, small geese 6, 6, 1, 7. In addition, keep about 3% of the backup geese.

Feeding begins one month before the breeding goose lays eggs.

When feeding, the content of concentrate and coarse feed in the diet should be judged according to the shape of goose dung. If the goose dung is coarse and loose, it can be divided into several sections with a little foot, which means that the coarse material, fine feed and green material are properly matched; if the goose dung is small and strong, it means that the concentrate is more than green and should be adjusted.

Laying geese are mainly fed in houses and supplemented by grazing.

Dietary nutrition to meet the nutritional needs of egg-laying geese, the dietary nutrition level should be: metabolic energy 11.3-11.7 MJ / kg, crude protein 16-17.5%, crude fiber 5%-6%, calcium 2.2%-2.6%, phosphorus 0.6%-0.7%, lysine 0.69%, methionine 0.32%, salt 0.3%. Three times a day, the daily feeding amount of each animal is 0.15 × 0.2kg, and the feeding effect is better at about 11:00 in the evening. In addition, 20%-25% green feed should be provided regularly, basins should be set up in goose houses and sports grounds, and clean shell grains should be added to allow geese to feed freely, so as to meet the mineral needs of breeder geese.

Reasonable replenishment of light

30 days before the beginning of laying, the artificial light should be increased by half an hour per week on the basis of natural light, and the artificial light should be kept for 16 hours from the beginning of laying to the whole laying period. The light intensity is appropriate to open a 40-watt ordinary light bulb every 12 to 15 square meters, and the bulb is 2 meters high.

Let the laying geese develop the habit of laying eggs in the enclosure

Goose flocks should be checked before grazing every morning. If individual geese are found to be singing uneasily, full belly, flat tail feathers, expanded cloacal cavity and slow movement, the goose that wants to go to the nest should be caught and touched, and if there are any eggs, they should be left in the circle and go out for grazing after laying eggs. Form the good habit of laying eggs in a circle.

Pay attention to the storage of planting eggs

Most of the eggs laid by the goose are concentrated between midnight and 8 a.m. the next day, and the eggs should be picked up around 10:00 and 4: 5 p.m. The eggs picked up should be timely recorded with a soft pencil on the top of the egg laying date, in order to grasp the appropriate hatching date of breeding eggs, but also help to check the quality of breeding eggs in different periods and timely adjust the feeding and management of breeding geese. Breeding eggs should be stored in a place with a temperature of 5 ℃ ~ 18 ℃, humidity of 65% and 75%, cleanliness and good ventilation. For dirty eggs can only be wiped with a dry cloth, it is forbidden to wash with water, because after washing the eggshell film is destroyed, pathogenic microorganisms are easy to invade and damage the quality of eggs.
