At home, chickens are fed for eggs and meat. Accordingly, they differ from each other in appearance and structure. Chickens fed for eggs are small and mature quickly, while those fed for meat are larger and develop better. Productive breeds of hens produce 220-250 eggs per year, some up to 365. The chick hatches from the eggs at the age of 5-6 months. The initial egg weighs about 40-50 grams, closer to 1 year it reaches 55-65 grams. Chickens live on average 10-12 years. Can lay eggs up to 10 years. On commercial egg farms, the economic benefit is that the chicks only keep them for a year after they are in the eggs, as egg production also declines as the hen ages. Only in breeding farms, productive chickens are left for 2-3 months. In all other cases, storage for more than 1 year may not give a good result. In poultry farms, chickens are fed grains, vegetables, mineral feed, vitamins, and other similar products.

    Further increase in the egg production of chickens in poultry farming is an urgent task. In this direction, a number of studies are being carried out at the Faculty of Biology of Samarkand State University. In particular, Guzel Normurodova, Master of the Department of Physiology and Biochemistry of Humans and Animals, under the supervision of Professor Safin Maris, is conducting a scientific study on the topic “The effect of enriching the diet of laying hens with Tokovit on physiological and productive indicators.”

    “From world experience, we can say with confidence that the enrichment of various vitamins and additional feed elements that make up chicken feed with enzymes gives a high effect,” says researcher Guzel Normurodova, “the purpose of our study is to study the effect of tocopherol (vitamin E) on the diet of laying hens , resulting in finding out to what extent it affects the physiological state and productivity of chickens. Tocopherol-vitamin E plays a crucial role in muscle development, increasing muscle mass. The lack of tocopherol in the human body leads to a decrease in muscle mass, muscle atrophy, and impaired muscle activity. Tocopherol is found only in plants and is not synthesized in animals. Vitamin E is an essential vitamin for living organisms as an antioxidant, regulator of transcription and enzyme activity, and as an activator of the immune system. 150-300 mg/kg of feed additives stimulate the activity of the immune system. Egg-laying breeds of chickens can get a large amount of eggs and meat by introducing tocopherol into their regular diet. This will undoubtedly be a cost-effective source of income for farmers and farmers
