Science raises chicken to pay attention to nine kinds of unsuitable matters

Chickens are not well-suited for raising in highland areas, particularly above 3,500 meters. At such altitudes, the air is thin and oxygen levels are low, which can't meet the oxygen and energy demands of broilers. This increases the workload on their heart and lungs, raises vascular permeability, and causes fluid leakage into the abdominal cavity, leading to water accumulation. Therefore, it's not advisable to raise broilers at high altitudes without proper preparation, as this can result in significant losses. During vaccination, it's important to avoid using disinfectants, especially in drinking water. Chickens should be kept away from sterilizing agents for 7 to 10 days before and after immunization. If disinfectants are used, they may kill the vaccine bacteria, reducing its effectiveness and causing immune failure. Distillers' grains should not be fed directly to chickens. These grains contain a high amount of crude fiber that chickens cannot digest due to their lack of teeth, short intestines, and limited cellulose-degrading enzymes. This can interfere with nutrient absorption and lead to digestive issues. Feeding bone meal to chickens is also discouraged. If the bone meal isn't properly processed under high pressure, it may contain bone glue that affects the calcium-to-phosphorus ratio in the diet. Over time, this imbalance can reduce egg production and overall productivity. Trichlorfon should not be used to treat parasites in chickens. The crop environment in chickens is alkaline, and trichlorfon can produce DDVP, a toxic compound that may cause poisoning. Instead, safer alternatives like carbendazim or levamisole are recommended. Immunizing chickens during the laying period is risky. It can lead to symptoms such as diarrhea, drooping wings, lethargy, reduced appetite, soft-shelled eggs, or even a complete halt in egg production. In severe cases, it may result in lameness, paralysis, or death. To minimize these risks, vaccinations should be scheduled during the resting period, and vitamin B2, yeast, and cod liver oil should be added to the feed 7 days before and after vaccination. Eggs should not be washed with water, as they have a natural protective film that prevents moisture loss and bacterial entry. Washing removes this layer, reducing egg quality and affecting hatching rates. Instead, eggs should be disinfected using a benzalkonium solution. Direct feeding of scorpions to chickens is not recommended. Although scorpions are high in protein, they can carry intermediate hosts like nematodes, increasing the risk of parasitic infections. If used as feed, they should be properly processed into a fine powder. Lime should not be used to disinfect chicken coops. Quicklime can cause burns to the chickens’ feet and, if ingested, may lead to gastrointestinal inflammation, ulcers, and respiratory issues. A safer alternative is to use a 10% to 20% lime emulsion sprayed inside the coop. By following these guidelines, poultry farmers can ensure better health, productivity, and safety for their flocks while avoiding common mistakes that could lead to serious consequences.

IM Rabies Vaccine

Rabies is a fatal viral encephalitis which can be effectively prevented by prophylactic measures. The currently available cell culture vaccines used for rabies prophylaxis are used by the standard intramuscular route of administration
