How to raise laying breeding geese? Detailed explanation of management technical points
The management focus for geese entering the laying period is to develop good living habits, so as to improve reproductive performance, lay a good production foundation, and ensure the output of many good goslings.
????1. Before laying, select the best and cull the inferior from the goose flock
For growing geese (replacement breeding geese), select and retain female geese that are moderate in body weight and condition, whose body shape, appearance, and feather color meet the requirements of the breed, and that start laying at the proper time (200-240 days of age). For experienced breeding geese, refer to past laying records and retain female geese that lay many eggs, have moderate egg weight (over 130 grams), have normal egg shape and shell color, and have no (or weak) broodiness. Male geese are required to have normal penis development and strong male vigor. About 30 days before the start of laying, inject the goose flock one by one with vaccines such as gosling plague, paramyxovirus disease, and new viral enteritis of goslings, and at the same time carry out deworming with drugs 1-2 times. The goose flock should be reasonably grouped. Each group should be 60-100 birds, and maintain an appropriate male-to-female ratio: 1:4-1:5 for medium-sized geese, 1:6-1:7 for small geese. In addition, keep about 3% replacement male geese.
????2. Start supplemental feeding one month before the breeding geese lay
When supplemental feeding, judge whether the content of concentrate and roughage in the daily ration is appropriate according to the shape of the goose droppings. If the goose droppings are thick, large, and loose and can be broken into several segments with a light nudge of the foot, it indicates that the combination of roughage, concentrate, and green feed is appropriate; if the goose droppings are small, fine, and firm, it indicates that there is more concentrate and less green feed, and adjustment should be made.
????3. Laying female geese should be mainly housed and supplemented by grazing
The daily ration nutrition should meet the nutritional needs of laying breeding geese. The nutritional level of the daily ration should be: metabolizable 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%. Feed 3 times a day, with a daily feeding amount of 0.15-0.2 kg per bird. Feeding once at around 11 p.m. gives better results. In addition, always provide 20%-25% green feed, set up feed basins inside the goose house and on the exercise ground, and add clean shell grit for the geese to eat freely, so as to meet the breeding geese's need for minerals.
????4. Reasonably supplement lighting
Thirty days before the breeding geese start laying, add half an hour of artificial lighting each week on top of natural lighting. After the breeding geese start laying and throughout the entire laying period, maintain 16 hours of lighting. The light intensity should be one ordinary 40-watt bulb per 12-15 sq m, with the bulb hung 2 m high.
????5. Let laying geese develop the habit of laying eggs inside the pen
Every morning before grazing, check the goose flock. If individual geese are found to be restless and honking, with a full abdomen, tail feathers stretched flat, enlarged cloaca, and slow movement, for female geese that want to go to the nest, catch and touch them. If they have an egg, they should be kept inside the pen and go out to graze only after laying. Develop the good habit of laying eggs inside the pen.
????6. Pay attention to the collection and storage of hatching eggs
Female geese mostly lay eggs from the second half of the night to 8 a.m. the next day. Eggs should be collected once around 10 a.m. and once at 4-5 p.m. The collected eggs should be promptly marked at the top with the laying date using a soft pencil, so as to grasp the suitable date for setting the hatching eggs, and also to help check the quality of hatching eggs in different periods and adjust the feeding and management of the breeding geese in time. Hatching eggs should be stored in a clean, sanitary, and well-ventilated place at a temperature of 5°C-18°C and a humidity of 65%-75%. For eggs with dirty surfaces, only a dry cloth may be used to wipe them. Washing with water is prohibited, because after washing the cuticle layer of the eggshell is destroyed, pathogenic microorganisms can easily invade and damage the quality of the hatching eggs.
