ANSC 4290 Lecture Notes - Lecture 4: Antinutrient, Soybean, Reduced Cost
Document Summary
What are the issues: e cient pork production. Digestibility/ availability: 1-9 diets all formulated in di erent proportions. Choosing a diet will be based on the cost of the diet. Diet 1: very common feed (corn and soy). > soybean meal has a larger majority of aa and so reducing soybean means we reduce protein but then we may be de cient in certain aa, so we need to add single. Aa back into the diet to make it complete. This also makes the diet more e cient and reduce waste of protein (excretion of n). If taking out more of the protein source (soybean meal) we reduce the crude protein but we supply the limiting aa with synthetic aa to ensure the diet is complete. Diet 4: added some corn ddgs to replaced a lot of the corn and some soybean but not saving much money.
