When chickens have chronic diseases (chronic respiratory diseases), 10% of vitamin A, vitamin E, and vitamin C should also be added. Adding 5% more vitamin A1 to the broiler feed can increase the feed conversion rate and help to speed up the growth and development of the chicken. For chicks, the lower the vitamin A content in the feed, the more the coccidiosis incidence of the chicken becomes. High, therefore, in the chicken coccidiosis, 20% more vitamin A, vitamin K, and vitamin C should be added to the feed. When the chicken suffers from fatty liver syndrome, 5% more choline chloride and 10% more multivitamins are added. During the hot summer months, adding 2% of vitamin C to the chicken feed can improve the resistance of the chicken body, reduce the temperature of the chicken body, improve the production performance, and reduce the stress response. During the peak egg laying period, 2% more vitamin B2 should be added. In order to increase the hardness of the shell, in addition to adding 2% of calcium in the feed, 2% of vitamin A and vitamin C should be added. When a flea and coccidiosis occur in the flock, one more amount of multivitamin should be added to the feed. When a certain vitamin deficiency occurs in the flock, the amount of vitamins in the feed should be three times that of the constant. The amount of vitamins in the feed for young chickens and breeders should be 2 times the amount of the constant. In general, caged chickens use 10% more multidimensional ingredients than free-range chickens. If the feed is used for a long time (more than 30 days), it should add 5% to 10% more multivitamin to make up for the loss of vitamins.
A Viscometer (also called viscosimeter) is an instrument used to measure the viscosity of a fluid. For liquids with viscosities which vary with flow conditions, an instrument called a rheometer is used. Thus, a rheometer can be considered as a special type of viscometer.[1] Viscometers only measure under one flow condition.
In general, either the fluid remains stationary and an object moves through it, or the object is stationary and the fluid moves past it. The drag caused by relative motion of the fluid and a surface is a measure of the viscosity. The flow conditions must have a sufficiently small value of Reynolds number for there to be laminar flow.
At 20 °C, the dynamic viscosity (kinematic viscosity × density) of water is 1.0038 mPa·s and its kinematic viscosity (product of flow time × factor) is 1.0022 mm2/s. These values are used for calibrating certain types of viscometers.

When the chickens have a stress response (vaccination, transfer, etc.), they should add 10% more vitamin A, vitamin E, vitamin D, vitamin C.
