Evaluation of bulls-producers of meat breed by the quality of offspring

Purpose. The purpose of the work was to test the bulls-producers of meat breed on their own productivity and the quality of offspring. Materials and Methods. In the course of the study, generally accepted zootechnical and mathematical methods of analysis were used. The digital material was biometrically processed on a PC using the Microsoft Office Excel program. Results. 3 groups of bulls were selected. The 1st group included bulls of the genealogical line of the bull-producer Runaway 2113, the 2nd group of the Journal line 2101 and the third Violent 2140. The average score for the 1st group of bulls was 34.5 and the complex index was 99.4, respectively, for the 2nd group 35.6 and 101.9 and for the 3rd group 34.3 and 98.6. Lifetime assessment of meat qualities showed that the bulls of the 2nd group had the best meat forms and surpassed their peers by 0.6-0.7 points. Conclusion. The evaluation of the quality of offspring showed that the most effective improvement of breeding and productive qualities in the breed can be achieved by using the bull-producer of the Journal 2101 and its descendants.
