Abstract

The objective of the research was to investigate the effect of multiphase nutrition, i.e. different mixtures used in broiler nutrition, whose protein content was reduced in several phases during the first fattening stage, on production performances of broilers. The investigation was carried out on 1216 individually tagged chickens of Ross 308 strain divided by sex. In the trial period (1st to 42nd day), standard fattening technology was applied, with four nutrition treatments (T1-T4). Chickens of the first group (control) were fed mixture containing 23% of protein in duration from 1st to 21st day, and in remaining three groups protein content during the trial period was reduced in several phases, according to specific program of multiphase nutrition. Programs of multi-phased nutrition, at the age of 42 days, did not influence the body mass of male and female broilers, meaning that the comparison of the surveyed groups (T2, T3 and T4) with the male and female broilers from the control group (T1) did not reveal any significant differences. The multi-phase nutrition program for the surveyed T4 group showed the most favourable feed conversion with the male broilers (1.870) and female broilers (1.867) in comparison to the representatives of the control group of male broilers (1.918) and female broilers (1.951). Based on results obtained, it can be concluded that multiphase nutrition affected the production performance, i.e. the level of feed utilization, which was in favour of its application, considering that difference in feed conversion could be decisive for realization of the positive economic production performance.
