[Effect of lighting intensity on protein metabolic indices in broilers].
Studies were carried out on illumination of varying intensity with regard to some indices of protein metabolism in raising broiler chickens. The changes were followed up in the content of total proteins in the blood plasma and that of liver and breast muscle proteins. Determined were the amount of blood serum urea and the activity of serum transaminases (GOT and GPT) along with the content of lipoproteids and free amino acids. The level of proteins in the blood, liver, and breast muscles was found to be higher in birds raised in the conditions of lower illumination intensity. The amount of free amino acids in the serum showed lower values with birds of the test group. The content of beta-lipoproteids was higher in birds raised under illumination of 4-5 lux/m2 intensity as against that in birds raised under illumination of 7.5 lux/m2.
