The method of raising female ducks during the laying period

From the beginning of the laying of the first egg to the peak of egg production known as the egg period. The main means of feeding management at this stage is supplementary feeding, and natural pastures should be used as much as possible to make ducks change their fur and store fat. Every morning when the ducks are released, they are supplemented with an early meal. The amount of supplementary feeding is generally 80% full. To fast fattening can eat a little more, but can not feed full, to encourage ducks to peck wild food. Supplemental feed can be the worst quality of the year, such as shriveled grain, germinated grain, floating wheat, floating beans, sorghum, etc., because ducks at this time can make full use of these inferior feeds. In order to stimulate the development of gonads, artificial lighting can be used when the illumination is insufficient. In order to make full use of natural light, we should put them early and harvest them late. In the grazing area with better wild feed conditions, ducks 'new feathers grew rapidly, body fat increased, yolk increased, some ducks were more active in action, often separated from each other to feed, and the feeding time was longer. If the grazing area is not rich in feed, ducks sometimes call loudly in groups, and it is necessary to add meals.

"Rain" before, is the duck fertilizer climax period. In grazing areas where wild fodder is poor, two meals are fed, the second usually at noon, and fed as full as breakfast. In order to prevent ducks fat body and egg production rate decreased, to add three meals, usually 6:30 a.m. to feed early, noon feed, feed late at night. Under normal circumstances, the egg production rate reached 50% before feeding four meals a day, the egg production rate of ducks increased significantly, can increase the number of eggs per day by more than 10%, three or four days can reach the egg production rate of 89%.
