Integrated Layer Nutrition October 3 and 5 2023 Poultry Nutrition ANSC 4280 Samantha Medeiros Historical Feeding of Layers 70% of the cost of poultry products is feed Poultry industry is a consequence of the Green Revolution started by the development of high-yielding grains by scientists such as Norman Borlaug Soybeans George Washington Carver recognized the value of soybeans as a source of protein and oil in 1904. His recommendation to rotate cotton crops with soybeans increased soil fertility and crop productivity Basic Layer Formula Corn 550.3 Soybean Meal 282 80% Corn and SBM Limestone 101 10% Limestone Vegetable Oil/Poultry Fat 43 Dicalcium Phosphate 15.7 Salt 3.5 Methionine 2.97 Layer Premix 1 Choline 0.5 Nutrient Specifications ME Poultry Kcal/kg 2,900 Crude Protein % 17 Animal CP % 2.5 Crude Fat % 3.5 Crude Fibre % 2.8 Calcium % 4.20 Phos Total % 0.50 Phos Av Poultry % 0.43 Ca/PavP Ratio 9.76 Sodium % 0.17 Chloride % 0.20 Amino 2023 Base Acids & minus Pork Layer MBM Bakery Feather CP min DDGS Enzymes MBMMeal Corn 551 605 515 513 571 571 508 495555 Soybean Meal 282 200 202 187 135 135 95 147145 Limestone 100 87 87 86 86 86 86 104100 Poultry Fat 43 27 20 16 8 8 0 9 0 Dicalcium Phosphate 15.7 0 0 0 0 0 0 7.32.3 Salt 3.5 1.9 0.5 0.5 0.5 0.5 0 1.51.4 Methionine 2.9 2.6 2.5 2.0 2.5 2.5 2.2 2.22.4 Layer Premix 1 1 1 1 1 1 1 1 1 Choline 0.5 0.5 0.5 0.5 0.5 0.5 0.5 0.50.5 Meat and Bone Meal 75 72 72 72 72 75 0 0 Bakery Meal 100 92 92 92 100 100100 Feather Meal 30 30 30 30 30 30 Lysine 1.5 1.5 2.3 2.3 1.85 Threonine 0 0 0 0.0 0 Tryptophan 0 0 0 0 0 DDGS 0 100 100 32 Phytase 0.1 0.10.1 Xylanase 0.1 0.10.1 Pork Meal 28 Total 1000 1000 1000 1000 1000 1000 1000 1000 1000 Cost $ 512 $ 450 $ 443 $ 441 $ 413 $ 413 $ 398 $ 427 $ 422 Cost Change $ (62) $ (7) $ (2) $ (28) $ -
