The breeding period of geese is generally only 5.6 months. In southern China, most of the winter and spring seasons are concentrated. In the north, they are concentrated in early June and early June. After that, the geese enter a long-term production period, so breeding geese are encouraged during the production period. Management is also one of the keys to raising the economic benefits of geese.
1 Adjust the geese
1.1 Elimination of unsatisfactory species of geese. After the production of the female geese is stopped, the geese and goslings can be eliminated first, and the rest of the legs and other parts of the geese can be disabled. The second is to eliminate the low performance of egg production, and the small size and the pubic space are below 3 fingers. Goose while eliminating excess goose.
1.2 In the newly-grouped group, gooses are supplemented at the same time as part of the geese are eliminated. The age structure of the common geese population is: 1 year old geese account for 30%, 2 year old gooses account for 35%, 3 year old gooses account for 20%, and 4 year old gooses account for 15%. The ratio of male and female geese in the new group is 1:3 to 5 for medium-sized gooses, 1:3 to 4 for large breeds and 1:6 to 7 for gooses.
2 Manual Forced Moulting Manual forced moulting can shorten the moulting time and make the laying of eggs more fragile after moulting.
2.1 First stop the artificial light, stop the material for 2 to 3 days, only provide a small amount of green fodder, but to ensure sufficient drinking water.
2.2 On the 4th day, the green roughage consisting of green material plus Fufu, bad residue and so on was fed.
2.3 About 10 days before the first reduction of the main wing feathers, if not effortless, the root dry, can be removed by root, or should be removed after 3? 5d again, and finally unplug the main tail feathers.
2.4 After the plucking, when the swans can not enter the water and prevent the rain and the sun from being exposed to the sun, they should be raised and fed in the sports ground to prevent inflammation caused by bacterial infection.
3 artificial living pull down goose breeding goose during the period of maturation can be artificial live pullouts to increase economic income.
3.1 pull down down the day before down to clean, and stop feeding only water, pull down the same day stop eating water, feathers wet goose to wait for down and then pull out (pull down is in addition to the head, wings and tail outside All parts of hair.
3.2 After weaving down, we must create a good environment for the geese, and we must strengthen the feeding and management. We should supplement the concentrate 150 to 180g per day, and the metabolic energy of the concentrates should be 10.9MJ and the crude protein should be 16.5%/kg. If conditions can also add 2% to 3% hydrolyzed feather meal is more appropriate. Can not be exposed to sunlight in 3d, 5? 7d can not let the goose into the water, if the wound is removed and the skin is to be treated after the wound healing, the goose house should be clean and dry.
4 Restriction Breeding during the breeding period should be based on grazing, and the production period should be changed to the ration diet. Improve the ability of geese to resist rough feeding, thereby reducing the cost of raising and increasing the economic benefits of geese.
4.1 Grazing According to conditions, seasons, and geese physique, a flexible grasp of the feed ratio and feeding amount, that is to maintain the normal geese, but also to reduce the cost of feeding, we must choose the riverbed, the lake, the hills, rich in aquatic plants that have not sprayed toxic substances. And harvested rice fields, wheat fields and so on. While grazing, attention should be paid to the dynamics of the geese and timely removal of sick geese should be kept separately. And pay attention to heatstroke prevention.
4.2 The average daily feed intake of female geese is generally reduced by 50% to 60% in this growth stage, and the feed can be filled with more coarse material, such as rice straw.
4.3 Good pasture quality The grazing land can also feed or feed less concentrate. If the grazing conditions are poor, it should be fed twice a day for 9 am.
4.4 Controlling the feeding period No matter how many feedings, the feeding time must be about 2 hours before grazing to prevent the goose from eating enough food before grazing and is unwilling to eat grass or feeding 2 hours after grazing, so that the geese will not develop after grazing. Feeding eager to return to the nest rather than eating the bad habits of grass.
5 resume feeding
5.1 First, gradually increase the supplement diet, nutrition levels and increase the amount of feeding and feeding times, dietary protein levels controlled at 15% ~ 17% is appropriate, after about 20d goose species can be restored to the level of control of the previous period.
After the 5.2 species of goose recover their weight, in order to make the moult tidy and shorten the moulting time and save feed, artificial moult must be carried out. The goose's pullout period can be as early as 2h for the female goose, so that the reserve goose can enter neatly and consistently. Egg production period.
