Wolfberry is a common symptom in intensive chickens. According to the different parts of the foraging, it can be divided into feathers, anal fistulas, and quail eggs. In production practice, we must pay attention to the reasons for separation and symptomatic treatment. main reason: 1, the breeding density is too large. The stocking density is too large, sinks and feed troughs are insufficient, and chickens compete for water, causing some chickens to lack nutrients and prone to paralysis. 2. The chickens have poor uniformity. At 0-20 weeks of age, chickens are in a period of growth and development, and the body weight and bones are rapidly growing. If they are improperly reared and managed, they will cause the birds to lose weight and the length of the chickens will not be able to reach the standards. This will result in poor tidy chickens, which will cause chickens to develop. Hey. 3, improper regulation of the chicken house environment. If the air inside the house is polluted and the harmful gas exceeds the standard, the chickens will become restless and have troubles; the temperature will be uneven and hot and cold will cause great stress to the flock and the chickens will be affected; The time is too long, the intensity is too great, or the light is not uniform. The external light directly shines on the flock of chickens. 4, dietary nutrition is irrational. Insufficient animal protein in the diet, or amino acid imbalance, the flock can not effectively use the protein in the diet, can cause sputum; lack of calcium and phosphorus, lack of vitamin B2, B6 and B12 can cause sputum. Common types and incentives: Anal fistula: licking the anus and the abdomen below are the most serious types of warts. They are commonly found in high-yielding caged chickens or in open-breeding chickens. The incentive is to cause anal fistula or torn tears when excessively large eggs are drained. High yield hens. It is also common in chicks that develop diarrhea. The cause of this is an anus with stinky faeces. 啄羽癖: Individuals who eat or feed on each other's feathers or fallen feathers, and bleed on the exposed flesh of the skin, develop into a mutton clam, which is common during the peak period of egg production and during the molting period, mostly with sulfur-containing amino acids and B vitamins. Lack of relevant. The quail eggs: When a hen just lays an egg, the flock will grapple for food. Sometimes laying hens also eat their own eggs, mainly in laying hens, especially high-yielding chickens. Due to lack of calcium or protein content in feed, often accompanied by thin shell or soft shell eggs. In addition, cockroaches are more common in chicks, cockroaches and cockroaches are more common in battles between roosters, and cockroaches are more commonly found in chickens whose feet are affected by ectoparasites. How to prevent and treat: In the prevention and control of deafness, we must first understand the reasons for the occurrence of similar disability and eliminate it, and then according to the cause of the diagnosis, take appropriate preventive measures. 1. Timely remove chickens that have strong mutual preference and keep them separately. The bitter-tasting anti-inflammatory drugs such as gentian violet, berberine, and chloramphenicol are rubbed on the site of the snoring, and on the one hand, the anti-inflammatory drugs on the one hand cause the chicken to quit and retire. As a precaution, use the used waste generator oil from the generator and apply it to the vulnerable area. Use its unpleasant smell and unattractive colors to make the chicken lose its interest. 2, cut off. Although it is not completely prevented, it can reduce the incidence and reduce the damage. 7-10 days of age have good effect of cutting off, and repair once before opening. To be precise and accurate, it's best to ask professionals to do it. Successful breaks can both prevent warts and reduce feed wastage. 3, light can not be too strong. The limit is 3 watts per square meter of incandescent lighting. The lighting time is strictly according to the feeding and management regulations, and the light is too strong and the chicken gizzards increase. Improper light control during the brooding period, prone to paralysis during the laying period, resulting in irreparable damage. 4, reduce the breeding density. Providing enough space for chickens can reduce the chances of embarrassment. 5, to enhance ventilation. Minimize the harmful gas content in the house. 6, strict control of temperature and humidity. Avoid crowded stacking due to environmental discomfort, irritability, and impatience. 7. Provide a well-balanced diet. Note that the corn content should not exceed 65%. No animal protein formula should pay special attention to the balance of amino acids, avoid single feed, and will receive good results. In addition, the addition of 0.2% methionine to the diet can reduce the occurrence of sputum. Each chicken is supplemented with 0.5-3 g of raw gypsum powder every day, and the feather clams will soon disappear. The salt deficiency caused by lack of salt, can be added in the diet 1.5% -2% salt, for 3 days -4 days, but not long-term feeding, so as not to cause salt poisoning. 8. Disperse the attention of the flock that has formed. You can dim the lights in the house or use red light. You can also leave the melon vines, tubers, and vegetables in their home for food to distract them. 9, make up gravel, improve digestibility. A hard, unbreakable gravel can be selected from the river sand. The size of the small rice grains used for the chicks and the size of the corn grains for the chickens can be blended in a diet of 0.5%-1%. Freeze-dried Vegetables into powder will not affect its nutrition. Normally heat-sensitive substances are lost at high temperatures. For example: traditional high temperature drying technology. Freeze-drying technology and sun drying, drying, spray drying and so on are drying technologies, different drying methods have different effects on the quality of products. Freeze-drying method has less damage to the product. The traditional drying method is above 0℃, while the freeze-drying technology is simply understood to sublimate the moisture of fresh food under the vacuum and low temperature environment, and retain its original nutritional composition, appearance, size and other biological characteristics.
