Özet
In this study the effects of 0, 50, 100, 150, 200 and 250 mg/kg boron (B) supplementation to diets of laying hens on tibia B, Ca and P (inorganic) concentrations, tibia weight and ash levels (in % and g DM), leucocyte counts (PBL) and positivity of ANAE percentages in peripheral blood were investigated. Boron caused significant (P<0.001) increases of tibia B concentrations but decreased tibia Ca level (P<0.001). Supplementation of B did not affect tibia ash and weight. Whole blood haematocrit and haemoglobin counts were insignificantly (P>0.05) increased by B additions. There was no effect of B supplementation on peripheral blood ANAE percentages and splenic plasma cell counts (SPCC). In general, evidence from this study suggests that the effects of B supplementation on mineral metabolism may be modified by treatment time, the age of the birds, or the type of animal used. But, further research is needed in order to investigate the interaction between B and Ca to obtain maximum beneficial effects on bone metabolism of laying hens.
