Disinfection is the physical or chemical method of destroying pathogens that remain on different vectors, thereby cutting off the route of transmission and preventing and controlling the occurrence of infection. Disinfection can prevent the spread of pathogens and infectious diseases. Especially important for broilers raised in chicken cages.

The battery cage for broilers farm disinfection is divided into two types: chicken disinfection and empty house disinfection. The effective disinfection determines the success or failure of the culture. Disinfection is the basic link in the whole feeding process. The following is a specific disinfection method:

Disinfection with chicken is a certain concentration of disinfectant liquid sprayed on chicken houses and poultry farming equipmen. It is an effective way to prevent and cure various chicken diseases. It can not only kill the virus, but also reduce the dust in the chicken house. It purifies the air to prevent the infection and spread of respiratory diseases. At the same time, it can adjust the temperature inside the house. In the summer, the temperature in the house can be adjusted. The chickens can be disinfected frequently, and the chicken manure can be prevented from producing carbon oxide, carbon dioxide and ammonia. And other harmful gases. In addition to the primary disease chicken, the pathogen mainly comes from the chicken inhalation and the introduction of people, cars and objects into the chicken house and then spread to the chickens. In order to control the occurrence of chicken disease in time, it is an important means to do a good job of air disinfection. Disinfection method with chicken: Broiler feeding is basically completed at the end of brooding. When the ventilation is gradually increased, the chicken is disinfected in the chicken house. Generally, the chicken house is 2-3 days after the second week of age. With a backpack sprayer, the spray head will be sprayed upwards, and the inner and the outer step will gradually step back spray. Once every three weeks, it can be used once a day. When entering the five-week age, it is twice a day in the morning and evening. The closed chicken house can be used after the big mouth bottle is added. Place it at the air inlet, and as the air enters the house, the disinfectant enters to achieve the effect of air disinfection. Disinfecting with chicken is generally a non-irritating, non-corrosive disinfectant. The commonly used disinfectant is a disinfectant containing iodine. The pure iodine solution is preferred.

After the broiler is out of the bar, rinse it first, then use 0.5% peracetic acid or a disinfectant containing chlorine to spray the solution as required. Spray it from top to bottom. Close the door and window immediately after spraying. Open the door and window to remove the padding after one day. The aim is to eliminate bacteria and viruses on the air and litter surfaces in the house. Disinfection should be thoroughly cleaned from top to bottom and from left to right. There is no weed, no garbage and no pollutants in the farm. It is necessary to move all the chicken equipment to the outside and wash it with water and then soak it with disinfectant. disinfection. The key to the thorough disinfection of the house is the one-time washing and disinfection. The disinfection must be added to the flushing. The flushing water must use tap water or well water. It cannot be considered as flushing without any drugs or using unclean water to wash the house. Not only does this not kill the bacteria and viruses in the house, but it also allows them to penetrate deep into the ground and cracks in the house.

Farmers who breed laying hens know that the eggshell quality of laying hens is an important indicator of the quality of laying hens. The quality of the eggshell directly determines the breakage rate of the egg and affects the production benefit of the laying hen. The nutritional factors of eggshell quality are mainly the calcium and phosphorus content and proportion in the diet, vitamins, trace elements, electrolyte balance and so on.

1. Ensure the intake of calcium in chickens and the retention time of calcium in the body: Considering the effect of calcium retention time on the quality of eggshells, when the dietary calcium content reaches the theoretical standard, it must also ensure the calcium feed. The particle size (8~12 mesh is good) makes it suitable for chicken absorption and utilization. The experiment proved that: using a full-thickness diet containing 3.5%~4% calcium, the calcium retention in the body after cooking is only 50%. Since the eggshells usually begin to deposit at dusk, the chickens do not get enough calcium supplements at night, which is why the eggshell quality is generally poor when feeding the whole powder diet for a long time. It can be overcome by adding 1% to 1.5% of calcium powder in the diet after 3 pm.

2. Control the effective phosphorus content and the ratio of calcium to phosphorus: the effective phosphorus content in the diet of the laying hen is maintained at about 0.4%, and the eggshell quality is better when the ratio of calcium to phosphorus is 4:1 to 6:1. However, if the effective phosphorus content is too high (0.45% or more), it will cause relatively insufficient calcium and high phosphorus and low calcium.

3. Vitamin supplement: Vitamin D3 is a necessary substance for calcium and phosphorus metabolism in laying hens. It can promote the absorption and conversion of calcium and phosphorus in the intestine, and can overcome the improper proportion of calcium and phosphorus to some extent. Generally, the amount added per kg of feed is 2,000 to 2,500 international units. The quality of eggshells is significantly reduced when vitamin D3 deficiency, failure, or other substances that interfere with vitamin D3 metabolism, such as aflatoxin or other fat-soluble vitamins.

4. Adding trace elements: Manganese and zinc are of particular importance in trace element premixes. At high egg production rates and high stocking densities, at least 70 grams of manganese or an equivalent amount of zinc or slightly higher per ton of feed is required. The magnesium can guarantee the quality of the eggshell, but high manganese will inhibit the absorption of zinc.

5. Maintain electrolyte balance: Chlorine is acidic in chickens, and high levels of chlorine are harmful to eggshells. Because the metabolic acid produced by high chlorine inhibits carbonic anhydrase, hinders the conversion of bicarbonate to carbonate; it also affects calcium and phosphorus metabolism in chickens. Sodium and potassium are alkaline in chickens and can be substituted with each other in a ratio of 1:1 to counteract the effect of excess chlorine in the diet containing normal amounts of sodium and potassium on the eggshell. Studies have shown that in the diet with normal calcium and phosphorus content, baking soda can be used instead of 0.1%~0.5% salt to effectively regulate the acid-base balance in the body, reduce the eggshell breakage rate, and add 0.3%~1% baking soda. Improve the hardness of the eggshell.

The above is how to improve the eggshell quality of laying hens when using chicken cages to raise chickens. I hope to help farmers.
