Question: How to increase the egg laying rate in winter?
The cold weather in winter, the reduction in duck and duck activities, and the decrease in the time of light exposure are not conducive to the production of eggs. Therefore, if they are improperly reared and managed, they will cause the winter ducks to cut production or even stop production. To this end, the reporter interviewed Zhang Huilin, associate professor of Animal Science and Technology College of Northwest Agriculture and Forestry University, and she emphasized that winter ducklings should pay attention to the cold and warm measures of duck houses, improve nutrition, and carefully feed, and let the ducks exercise properly. To enhance physical fitness.
Duck house is cold and warm
In winter, due to frequent cold air activities, sometimes the temperature drops abruptly, which makes it difficult for the ducks to adapt and causes the laying rate to decrease. The temperature is very important for laying ducks. The optimum temperature for laying ducks is 13°C~22°C, and the lowest temperature should not be lower than 6°C. Therefore, winter must be done duck insulation and cold work.
Zhang Huilin introduced that the main methods of keeping ducks cold and warm are: to seal the doors and windows, it is best to nail the plastic film in the window and hang the straw curtain at the door; to keep the hay dry, the hay should be soft, and the length of the grass should not be removed. This can increase the comfort of laying ducks and ducks, but also make the bottom of the grass to ferment heat to produce a certain amount of heat; the use of artificial heating methods to supplement heat, but pay attention to safety, to prevent the occurrence of fire, poisoning and other events. At the same time, raise the stocking density and raise 8 to 9 eggs per square meter. In addition, duck housing should also pay attention to ventilation.
Keep feeding mixed feed
The quality of feed directly affects the egg laying rate of ducks. Only by insisting on feeding mixed feeds to meet the nutritional needs of laying ducks for laying eggs can increase the egg production rate of ducks.
Therefore, we must insist on feeding mixed feeds produced by feed processing plants. If we cannot buy mixed feeds, we can also prepare mixed feeds ourselves. Its formula proportion is: 48% cornmeal, 25% soybean cake or sunflower cake, 10% wheat bran, 5% sorghum flour, 7% fishmeal, 3% shell powder, 2% bone meal, and 0.2% salt. You can also add some green vegetables each time you feed, or add 10 grams of veterinary multivitamins to 100 kg of mixed feed, and stir evenly before feeding. Feed 3 times a day, add 1 night snack at night, and provide plenty of water.
Timely release of water and proper exercise
Every day, you should keep a certain amount of clean water in the drinking fountains, but you must do less to make the ducks drink water at any time. At the same time, the ducks put water to grasp the weather, time and frequency. On sunny days, water should be released around 9 a.m. and 2 p.m.; Cloudy or light rainy weather, once in the morning, water should be kept in the afternoon; Cloudy or heavy rainy weather, water should be released every other day, frosty weather, no water can be released. .
Zhang Huilin said that at least 4 times before the release of water, "noise duck" is to gently drink the ducks in the shed to make it all get up and do circular motions in the home, each time at least 5 laps to increase the amount of exercise, enhance Constitution, while improving the duck's ability to keep out the cold, when more than 80% of ducks make a strong call and then open the shed to release water, to avoid catching cold when directly into the water.
At present, there are nearly 100 kinds of plant extracts popular in the world, and the common ones are as follows:
1. Antioxidants: grape seed extract, green tea extract, pine bark extract, etc.;
2. Immune modulators: ginseng extract, gynostemma pentaphyllum extract, ganoderma lucidum extract, etc.;
3. Improve cardiovascular system function: Ginkgo biloba extract, lotus seed heart extract, rhodiola rosea extract, etc.;
4. Sedatives: valerian extract, hop extract, etc.;
5. Natural pigments: lycopene, purple potato extract, etc.;
6. Functional sweeteners: licorice extract, stevia extract, etc.
