[Changes of some metabolic parameters of the liver in chickens under the influence of Entomoxan]

From the 3rd week of life Studler-Cornish-breed chickens received a food mixed with Entomoxan (15 ppm HCH-gamma-Isomer in the food) for an 8 weeks period. 2,4,6, and 8 weeks after the beginning of the experiment livers of the chickens were examined for RNA-, DNA-, total protein- and total aminonitrogen contents. The RNA-values decrease constantly where as those of DNA increase up to the 4th week and after that decline. Total protein contents rise up to the 4th week. After 2 and 8 weeks the contents of amino-nitrogen are lower in experimental birds than in controls.
