Abstract
Aim: To establish the zero nitrogen corrected apparent (AMEn-o) and the true (TMEn-o) metabolizable energy of two batches high – protein (dehulled, with 45 and 50% crude protein in DM) sunflower meal.
Material and Methods: Standardized methods for balance experiments with poultry. The roosters were 1 year old – White Plymouth Rock – race. Six birds were tube fed and six feed deprived per each batch of fodder. Separately experiments with intact and caecoectomized roosters were conducted.
Results: The following levels (J/g DM) have been established: Batch 45%: (AMЕn-o): intact: 8430, caecoectomized: 8317, mean: 8373; (TMЕn-o): intact: 9221, caecoectomized: 9108, mean: 9164. For the batch 50% the results were: 9281, 10061, mean - 96711 and 9943, 10973, mean - 10458 J/g DM respectively.
Conclusion: The authors suggest that both feed batches can replace isoenergetic soybean meal in combined fodders for poultry.
