Duck duck feather refers to the bad behavior of a duck in the process of breeding, one or more ducks in the group self-licking or attack other individual feathers. The sniper site is mostly sparsely feathered at the back and wing tips, bleeding from the hair follicles, and even tearing of the skin. The feathers are often eaten after they are picked up. The occurrence of deafness caused the ducks to become turbulent, hurt, and loss of appetite. Seriously affected the normal growth of ducks.
The reason of duck feathering is mainly due to improper feeding and management.
Poor environmental conditions such as high stocking density, lack of exercise, overheating, excessive humidity, poor ventilation of the housing, ammonia and carbon dioxide concentrations exceed the tolerance of the duck population, excessive light, light and dark uneven distribution of light or light color and other unfavorable.
The lack of nutrients in the diet or the nutritional ratio of the diet is unreasonable, resulting in insufficient protein or amino acid deficiency, insufficient inorganic salt, vitamins, or lack of salt for a long period of time. Feeding time is not fixed and is full of hunger. In addition, depilation caused by the lack of cobalt is also prone to induce feathering.
Improper rearing and management of duck dung is not timely. Fermentation produces toxic substances such as toxins and ammonia. It stimulates the skin of the duck's body to itch. The disorder of the feathers in the captivity and contamination can also lead to self-deficit.
Mosquito bites summer mosquitoes, flies, and other blood-sucking pests to multiply, and bite meat ducks, causing itchy surface and causing spasm. Because the big hairs at the tip of the duck's wings just started to grow around the age of 24 days, the site was most severely contaminated, resulting in bleeding and damage to the hair shaft.
Prevention and control of cockroach feathers to improve the feeding environment, strengthen feeding and management to evacuate the culture density, improve ventilation and light intensity. The cage design height should be 100 cm to 120 cm for cleaning. Duck house temperature and humidity should be suitable to meet the temperature requirements of different day-old ducks, relative humidity is maintained at 60% to 70%, good ventilation, light is not strong, keep clean, dry ground, people do not feel like going into the duck house Bored, not irritating the nose.
Newborn ducklings should be cut off in a timely manner to cut off the newborn ducklings from the 8th to the 10th day of age. Using a duck electrocution device to stew the duck tips will completely avoid the occurrence of earthworms.
Scientifically formulating full-priced feeds should be fed with high-quality full-price compound feeds to provide adequate and adequate protein, vitamins, inorganic salts, etc., and fed regularly. The feed ingredients should be diversified, the formula should be scientific and reasonable, and high-quality, full-price diets should be given according to the age of ducks. Due to insufficient calcium and phosphorus protein, add 5% bean cake or 3% fishmeal, 2%~4% bone meal or shell powder. Add 1%~2% salt in feed due to lack of salt, feed 2 days~3 days , due to lack of sulfur can be caused by zinc sulfate or calcium sulfate, 1 g per day to 4 grams per day, appropriate to add green feed or feed Yu Ling Ling, feather powder, can prevent armpit hair.
Reduced light intensity is generally illuminated with 25 watt bulbs, ducks can see food and drink on it. The duckling can be used with red light, orange-yellow light, and big duck with red or white light, so that the ducks can be grouped and their hairs can be reduced.
Periodical killing of mosquitoes and flies should pay attention to drug concentration and use methods to avoid poisoning. Add vitamin B12 in drinking water or feed properly to prevent deafness induced delirium.
Prompt treatment should be promptly separated and treated. The wounds should be washed with potassium permanganate solution or coated with gentian violet or erythromycin ointment. Afterwards, they should be grouped together after healing to avoid further spread of sniper behavior. Appropriate exercise, in the feed by adding the right amount of natural gypsum powder, generally 1 g to 4 g per chicken per day, will soon be controlled.
