Duck ducks “falling eggs†refers to female ducks raised in the spring and enter the egg production period from November. At this time, the weather gradually becomes colder. The temperature difference between day and night is too large or due to lack of nutrition, resulting in the suspension of production of laying ducks. ". When ducks have smaller eggs, smaller eggs, thin shells, delayed egg production, feathering, or wet feathers after watering, they should promptly take the following measures:
Adjusting the duck group to the early winter, the old, weak, sick, and disabled ducks in the duck group will be eliminated in time, leaving the mother ducks with good production performance and robustness. At the same time, it is appropriate to provide some more ducks, so that they can chase each other and increase the amount of duck exercise.
Raising the level of feed nutrition appropriately increases the proportion of corn, broad beans and soybean cake in the diet, controls the feed intake of ducks, and improves feed nutrition.
Cold and warm duck shed holes to be plugged, doors and windows to be hung with straw curtains, shed thick cushions in the ground dry soft thatch, straw and other objects to ensure that the duck abdomen from the cold. At the same time, we must also pay attention to the relevant health and epidemic prevention work to ensure the health of ducks and ducks.
Adding light to the duck requires 16 hours of light each day during the laying period. The winter nights are long and short, and the light illumination is insufficient. Therefore, 40 to 60 watt bulbs (one for every 20 square meters) must be installed in the duck shed. The bulbs should be 2 meters high from the back of ducks and be covered with shades so that the light rays can be concentrated. On the body of the duck, the light should be even and take 3 to 4 hours every night.
Noise and noise ducks can enhance the cold resistance and digestion of ducks and prevent the duck from stopping production. The practice is to gently sip ducks in the duck shed to start, slowly in the same direction to do a circular motion, usually around 4 to 5 laps every 1 hour to catch 1 time per day to catch 2 or 3 times. In particular, ducks should be noisy before they go into the water. When more than 80% of the ducks cry loudly, ducks can only be put into the open water to increase the adaptability of ducks to the temperature and water temperature outside the greenhouse.
Adding Cod Liver Oil Cod liver oil is rich in vitamin A and vitamin D, which is beneficial to enhance the immunity of ducks and stabilize the egg production rate. Specific feeding method: Feed 1 ml of duck per day, mix the cod liver oil in the bran first, then mix well in the feed and feed it for 3 to 5 days. If the duck has normal egg production, the feather light can stop feeding.
