  • Title: [Effect of population density during raising on amino acid levels in the serum and various organs of broilers].
    Author: Dzhankov T.
    Journal: Vet Med Nauki; 1982; 19(2):92-7. PubMed ID: 7112934.
    Abstract:
    Experiments were carried out on a productional premise of controlled microclimate. Broilers were raised under one and the same conditions of keeping and feeding at two density values - 14 and 22 birds per 1 m2 of the flooring area. The level of amino acids was followed up in the blood serum, liver, and the red and white muscles of the broilers of the two groups. It was found that at higher rates of population (22 birds per 1 m2) the biotic-ecologic factors were influenced the integral effect being the activation of catabolism of proteins in the body of birds. At higher density the amount of amino acids in these organs was found to drop, changes being observed also in the amino acid profile. Nitrogen in the feed was also influenced positively in terms of its conversion into amine nitrogen.
