First, in the spring of the river in February, although the temperature is still relatively low, it still allows the ducks to enter the water for about half an hour each day. The egg production decreased slightly in the first two days and returned to normal after one week. Its practical significance: Since March, temperatures have risen, pathogenic microorganisms have grown in large numbers, and epidemics have begun to multiply. In March, April and May, it is also the peak period of egg production. At this time, entering the river can be a benign stimulus to ducks and ducks, strengthen their resistance to disease, and strengthen the duck body, and finally achieve high yield.
Second, avoiding rain in the summer is the first step to prevent rain, the ducks and ducks get cold, and the immunity is reduced. The second is to prevent the filthy water of the ducks after the frolicking of the rain, especially the filthy water. The rate of bowel disease in captive ducks drinking such water is very high, and the drop in egg production rate is also very significant. When it rains, at the peak of the egg production, the duck group should stop its activities on the playground and return the ducks to the duck house. After the rain, after removing the dirty water, the ducks should be released.
Third, the fall of the fruit in the fall of the mountain matures, mountain soil or puree contains a lot of vitamins, minerals and many growth factors. If the ducks in this period just fall from the peak of the egg production or when the moulting is completed, there is an urgent need for certain nutritional factors, and at this time the “uphill†of the ducks will have unexpected effects.
