The research was conducted with the aim of determining the influence of the feed structure in the meal on the production indicators of calves in the post-weaning phase. The female calves of the Holstein breed were divided into 3 groups according to the treatment, and there were 6 animals in each group. The treatments were divided as follows: the control group (K) was fed a pelleted GT-1 mixture, the first experimental group (P1) was fed a mixed meal of dry TMR and pelleted GT-1 mixture in a ratio of 40 : 60 % in favor of TMR, the second experimental group (P2) was fed with dry total mixed ratio (TMR). Calves were fed ad libitum with freshly prepared feed and water. The research lasted 30 days. The following production indicators were monitored: daily gain, total gain, feed consumption, feed conversion, body measurements, anamorphism and body compactness indices. Among the biochemical indicators in the blood, the values of glucose, creatine, urea, ratio of urea to creatine, total protein, albumin, globulin, ratio of albumin to globulin, triglycerides, alanine aminotransferase, aspartate aminotransferase and alkaline phosphatase were monitored. Weighing, taking body measurements and blood sampling were done on the 1st and 30th day of the research. No significant differences were found in total and daily growth, body measurements, as well as in anamorphosis and body compactness indices. There were no significant differences in the biochemical indicators in the blood. Feed consumption and conversion was the highest in the P1 experimental group. Based on the results of this research, we can conclude that the combination of starter for calves GT-1 and dry TMR proved to be the best choice in terms of food consumption.
