An experiment on Lohmann male broilers was conducted to evaluate the effect of different energy and protein levels on broiler performance and plasma concentrations of growth hormone (GH), thyroxine (T4), and triiodothyronine (T3). 600 day-old broilers were fed on either 2800(low-energy) or 3200(high-energy) Kcal ME/Kg diets with different protein levels during three periods of starter, grower a...

Two experiments were conducted to examine the calcium requirements of broiler chickens fed corn-soybean meal diets. Experiment 1 used a 6 x 2 x 2 factorial arrangement and was conducted with broilers in floor pens during the grower phase (19 to 42 d).
