The influence of different fat sources on fattening of turkeys and composition of fatty acids in breast muscles

Abstract

The aim of this research was to evaluate the influence that different fat sources (Bergafat-BF, Pronova Biocare Epax 3000 TG-PBE and rape oil-RO) have on fattening characteristics of turkeys and composition of lipids in breast muscles, if added separately in the amount of 3% and also equally combined in finishing diets. The research was carried out on 180 heavy hybrid turkeys of Nicholas 700 provenience. Different sources of fat did not have statistically significant effect (P>0.05) on finishing weights, average daily weight gain, consumption and feed conversion. However, supplementation of the above stated fat sources changed highly significantly (P<0.001) the content of SFA, MUFA and EPA+DHA in the lipids of breast muscles. Rape oil, which was added to diets, had positive effect on the content of SFA and MUFA. In comparison to non-supplemented diets, supplementation of Pronova preparation to diets resulted in doubling of the desirable EPA+DHA.
