Analysis of Causes for Decreased Egg Production in Ducks
The decline in gible production in ducks and ducks was due to the cause of salpingitis in ducks. Ducks suffering from this disease require 24-26 hours for the follicles to enter the fallopian tube. Egg ducks usually have more eggs in the morning. How many eggs are not received in the afternoon, if the eggs collected in the afternoon are generally due to inflammation of the fallopian tubes, the delayed laying of eggs for a long time is reflected in the decline in egg production. The decrease in the production of guts in laying hens was found in the newly-opened duck populations. Breeding ducks began to appear after fertilization and increased day by day. Duck salpingitis usually comes out of the fallopian tube with a white pus-like inflammatory exudate. The feathers under the anus are often contaminated with inflammatory substances. Difficulties in laying ducks are painful, and blood stains often appear on eggshells. With the development of the disease, the abdomen is getting larger day by day, standing and walking in a “penguin†posture, fullness in the abdomen, a touch of a sense of volatility, sick ducks with pain and anxiety, elevated body temperature and other symptoms, sometimes lying in a drowsiness and walking on the abdomen land. Inflammation can cause peritonitis. High-yield ducks are prone to salpingitis. Duck salpingitis is caused by many reasons, such as feeding too much animal feed, lack of vitamin A, D and E in feed, or producing double yellow eggs, eggs in the fallopian tube rupture, bacteria into. In addition, early infection with transmission virus or chlamydia, E. coli or Salmonella, corn mold may be one of the causes of the disease. So far, there are no effective drugs for the effective treatment of duck salpingitis, and it has been found that diseased ducks should be eliminated immediately and the normal duck population should be administered preventively. The egg production rate of the non-disease ducklings, and the fertilization rate and hatching rate of the breeding eggs should be eliminated. The production performance of the offspring is basically normal, and the eggs can still be reserved for seed use.
