This paper deals with the influence of the fedd level on the results of the performance test of Large White boars between 30 and 100 kg live weight. The average production results were as follows: the age of boars at the beginning of the test was 87.07 days, the age at the end of the test was 165.61 days, daily weight gain 0.904 kg, daily feed intake 2.30 kg, conversion ratio 2.55 kg and the average thickness of bacon was 16.34 mm. To appraise the influence of the systematic factors of the environment on the tested characteristics of the boars, the analysis of the variation according to the LSQ method was used. The phenotype affinity between the fattening indicators is determined by the correlation coefficients. The higher daily feed consumption was connected with a shorter fattening period with a higher daily weight gain and a higher feed conversion ratio. The results show a significant influence of the level of feed intake on the phenotype declared indicators of boars production and could be used in the breeding.
