Effect of Feeding Constant or Different Levels of Protein Through Sorghum Based Diets on the Performance of Broilers

One hundred sixty broiler chicks (4d) were randomly distributed in 20 groups. Five sorghum based isocalorlc diets (2900 kcl ME/kg)’were formulated to contain 26, 24, 22, 20 or 18% CP. Each diet was alloted to 2 groups of 8 chicks in each for 5 weeks. While from remaining groups each of the two groups were fed 26–24, 24–22, 26–22, 22–20 or 20–18% CP dietduring 0–2 and 3–5 weeks, respectively. Best performance (weight gain, feed utilization, and performance index) and profit per broiler was observed In broilers fed dlet.containing 26% CP and 2900 kcal ME/kg, constantly for 5 weeks. Feeding constant level of protein was beneficial over feeding two different levels of protein during 0–2 and 3–5 weeks. I was concluded that 26% CP along with 2900 kcl MEVkg diet would be most economical with sorghum based diet.
