When ducks have individual eggs that become smaller, the shells become thinner, the time for laying eggs is delayed, the feathers on the shore are wet, and the symptoms of “falling eggs†are drilled into the duck house. The following measures must be taken in time:
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 ducks.
Feed protein feeds should increase the proportion of corn, broad beans and bean cakes, control the feed intake of ducks, and increase feed nutrient concentration.
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 egg and duck requires 16 hours of light each day during the egg production period. The winter is short and long, and the lighting is insufficient. Therefore, 40 watts to 60 watt bulbs (one per 20 square meters) should be installed in the duck shed. The bulb should be 2 meters high from the back of the duck and should be covered with a lampshade so that the light can be concentrated on the duck body. The light should be uniform. Take 3 hours to 4 hours at night.
"Catch the shed"
"Catch sheds" can enhance the cold resistance and digestive ability of ducks and prevent the ducks from stopping production. The practice is to gently snuggle 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, 2 times a day can be rushed to 3 times. Especially before catching ducks, they should also “catch shedsâ€. When more than 80% of ducks shout loudly, ducks can 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 Because cod liver oil is rich in vitamins A and D, it is good for strengthening duck immunity and stabilizing egg production rate. Specific feeding method: Feed 1 ml of duck per day, mix the cod liver oil in 1.5 kg of bran first, then mix well in the feed, feed 3 days to 5 days after feeding, if the production is normal, feather light can be stopped, often Eating will affect economic efficiency.
Early winter to prevent ducks "falling eggs"
Duck ducks "falling eggs" refers to female ducks raised in the spring and enter the egg production period from November. At this time, the temperature gradually gets colder. The temperature difference between day and night is too large or due to lack of nutrition. As a result, the egg laying duck is discontinued. ". If the ducklings "fall their eggs," they will begin to change their hair, and it will take until next spring to produce eggs. If the ducks can be controlled to "fall eggs" during this period, the egg production period can be greatly extended and the economic benefits of raising ducks can be improved.
