Abstract

The objective of this study was to evaluate the effect of dietary conjugated linoleic acid (CLA) and false flax (Camelina sativa) seed oil (CS) on bone quality in broiler chickens. Experiment was carried out on 96 chickens randomly divided into four groups: control group fed diet with sunflower oil (SO) and three experimental groups fed diet with addition of CLA (2.86% starter, 4.32% grower) and diet with addition of CLA (1.43% starter, 2.16% grower) and SO or CS (1.43% starter, 2.16% grower). On the 35th d of life eight birds per treatment were slaughtered and the femur, humerus, and tibia were isolated for further analysis. Using DXA method, bone mineral content (BMC) and bone mineral density (BMD) were measured. Furthermore, weight and length of bones were assessed. The weight, BMD, and BMC in chickens from CS+CLA group were significantly higher when compared with CLA group. The significant differences were noted for BMC between control and CS+CLA birds. No marked differences of bone parameters were observed between control group and CLA, and SO+CLA groups. In conclusion, the results indicate that false flax oil and CLA can replace sunflower oil in chickens feeding, and demonstrate the effectiveness of false flax oil on the enhancement of bone properties in broiler chickens.

Abstract

The introduction of this article outlines the terms and conditions of food control in the Slovak Republic and the institutions that provide it. This section also provides the comparison of inspection results in selected periods. The second part of the paper describes the measurement of the regional transport of perishable food products. The measurement compares all permitted temperature tolerances and is subsequently evaluated. The results of the measurements are also compared with the analysis of the number of checks carried out.
