Abstract:
In the present study, the influence of dietary Nano chromium (Nano Cr) on egg mineral contents of egg type chicken was studied. A total of 240, twenty two weeks old layer chickens (Babcock) were divided into 5 treatment groups (T₁, T₂, T₃, T₄ and T₅) with four replicates of twelve chicks in each. The birds were reared under standard management conditions for 12 weeks. T₁ did not receive Cr and acted as control. T₂ and T₃ groups were fed dietary inorganic chromium chloride, while T₄ and T₅ fed Nano Cr at 200 µg and 400 µg per kg feed, respectively. Eggs collected at the end of the study period were used for egg yolk and shell mineral content analysis. Based on the data obtained, it was concluded that Nano Cr supplementation at 400 µg per kg layer diet, improved the zinc content in egg yolk and shell, and chromium and calcium content in egg shell alone.
