Afeeding trial was conducted in layers for a period of8 weeks (23-30 weeks old) to evaluate the effect of chromium picolinate supplementation on egg yolk cholesterol and egg chromium content in layers.Atotal of (n=120) layers were randomly distributed in completely randomized design into 4 treatmentgroupseachwith2 replicates of 5chicks.The layers of treatment group T1(control)were provided water without chromiumwhile those of T2,T3andT4were provided water containing 200, 400 and 600 ppb chromium / litre respectively.At the end of feeding trial, six eggs from each replicate, on last three days were used for egg yolk cholesterol and egg chromium studies. The results indicated that the total cholesterol andLDL cholesterol content of eggs were significantly (P0.05) reduced and HDL-cholesterol content significantly increased in 400 and 600 ppb chromium supplemented group of layers. Whereas chromium content of eggs increased with increasing levels of chromium supplementation. It was concluded that organic chromium supplementation up to 600 ppb level through water may be advisable to reduce egg yolk total cholesterol and LDL- cholesterol and improved HDL-cholesterol and egg chromium content.
