An experiment was conducted to determine the relationship between plasma Ca, cholesterol, and triglycerides in commercial laying hens. A 2 X 2 factorial arrangement of treatments was used with two levels of dietary iodine (0 and 5,000 ppm) from KI and two levels of beta-estradiol (0 and 12 mg in a single subcutaneous injection), in a corn oil carrier. Feeding iodine or injecting beta-estradiol resulted in increased plasma Ca, cholesterol and triglycerides. The increases were additive for the two treatments. Plasma Ca and cholesterol was significantly correlated. Plasma Ca was negatively correlated with triglycerides when the hens were injected with beta-estradiol. Cholesterol and triglycerides were correlated when hens were injected with beta-estradiol. However, feeding KI decreased the correlation between Ca and triglycerides, and cholesterol and triglycerides.
