Effect of Adding Different Boron Sources to Diets Containing Low Calcium and Phosphorus on Some Bone Parameters of Weaned Akkaraman Lambs
(Ankara Üniversitesi, 2021-09-04) Sarıçiçek, Zehra; Yıldırım, Birgül; Ziraat Fakültesi
The aim of this study was to investigate the effect of addition of different boron sources (ulexide, colemanite, etibor-48) to diet containing low Ca, P on bone parameters and bone strength in weaned lambs. 50 Akkaraman single male lambs weaned at 2.5 months of age were used. Lambs were divided into 5 groups. Groups were; positive control, negative control, supplementation with colemanite, supplementation with etibor-48, supplementation with ulexide. Roughage and concentrated feed was given twice in day. At the end of 90 days, 6 animals from each group were slaughtered. The weight, dry weight, length, width and ash levels of the femoral and tibial bones were significantly increased in added boron (B) sources groups compared to negative control. With the supplementation of the colemanite and ulexide to diets, the femoral and tibial Ca content was higher compared to negative control. The P content in the femoral bone increased in groups added of all boron sources than that in negative control, also in tibial P content in the colemanite and ulexide groups increased compared to negative control. The supplementation of all B sources had improved B levels and breaking strength of bones compared to controls.
