Leg strength and performance of large white tom turkeys fed various protein and energy levels.
Three floor-pen experiments were conducted to determine the effects of varying protein and energy levels on body weight, feed efficiency, mortality, bone breaking-strength, and bone ash, calcium, and phosphorus in large white male turkeys. Increasing metabolizable energy by 100 kcal/kg diet increased body weight and feed efficiency. Increasing dietary protein during starter or finisher periods by 15% resulted in increased body weights by as much as 12%. Modifying dietary protein and energy levels over these ranges did not affect bone strength of toms at market weight.
