The objective of this study was to evaluate the effect of dietary conjugated linoleic acid (CLA) and false flax (Camelinasativa) 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.

The aim of the present study was to determine the effect of administration of Camelina sativa oil (CO) as a source of polyunsaturated fatty acids (PUFA) on bone parameters in ovariectomized rats (OVX). Overall, 40 10-week-old healthy female Wistar rats were divided into 4 groups with 10 animals in each. Rats in the control group (SHO) were subjected to a sham operation, whereas experimental rats (OVX) were ovariectomized. After a 7-day recovery period, the SHO the rats received orally 1 mL of physiological saline for the next 6 weeks. The OVX rats received orally 1 mL of physiological saline (OVX-PhS), 5 g/kg BW (OVX-CO5), or 9 g/kg BW (OVX-CO9) of camelina oil. The use of camelina oil had a significant effect on body weight, lean mass, and fat mass. The camelina oil administration suppressed the decrease in the values of some densitometric, tomographic, and mechanical parameters of femur caused by estrogen deficiency. The CO treatment increased significantly the serum level of osteocalcin and decreased the serum level of C-terminal telopeptide of type I collagen in the OVX rats. In conclusion, camelina oil exerts a positive osteotropic effect by inhibiting ovariectomy-induced adverse changes in bones. Camelina oil supplementation can be used as an efficient method for improving bone health in a disturbed state. However, further research must be carried out on other animal species supplemented with the oil.
