title: [Chemical makeup of the musculature and liver of fattening calves having degenerative osteoarthrosis].
abstract: Studies were carried out on the chemical composition of the muscles/m. gracilis, m. longissimus dorsi, caput longum of m. triceps brachii, as well as the muscles of the neck between the 5th and 7th neck vertebrae and livers from 16 spontaneously ill with osteoarthrosis degenerative calves, meant for fattening, of the breed "Bulgarian Brown Cattle." The studies were carried out with regard to the contents of general, extractive and protein nitrogen, ashes, as well as the quantity of the aminoacids tryptophan and hydroxyproline. The contents of adequate and inadequate proteins was determined, as well as the relative nourishing value of the proteins from the samples under investigation. A tendency was accounted for towards a reduction of the nourishing quantitites of the samples studied, taken from the sick calves, as compared with the data about the healthy animals, but this tendency was very slightly pronounced and in most cases was statistically ensured (P greater than 0.05).
