✦ Synopsis

More and more work points towards the possibility of selecting pigs by utilizing the early indexes of fattening and slaughtering group. This work attempts to observe the early biochemical indexes which could indicate the later commercial value of pigs. An investigation was made of the ribonucleic acids, which take an active part in cytoplasmic biosynthesis of the protein forming the main mass of meat tissue in the animal.In this work, an attempt is made to observe an interdependence between the content of ribonucleic acid in leucocytes and lymphocytes of pigs 'blood and the level of the animals' productivity. The results obtained permit the following conclusions: 1. No statistically significant differences for the sexes were noted between P-RNA level in the leucocytes and lymphocytes in peripheral blood and fattening indexes and meat utility. 2. The dynamics of RNA in leucocytes and lymphocytes of peripheral blood may form a criterion for selecting earlier or later maturing time. 3. The obtained coefficients of correlation between the content of P-RNA in blood leucocytes and lymphocytes and the fattening growth and meat utility of pigs suggest that these blood indexes may be used as a criterion for selection, according to which the future fattening and meat output could be forecases during the initial period for pigs growth (4th month of life). 4. The results obtained may be of wider importance from the breeding point of view, providing that future investigations are performed on much wider populations of animals.
