Nutritional Requirements of Non-ruminant Animals Objectives • Evaluate the protein requirements and what is required of a non ruminant animal • State the nutritional requirements of non ruminant animals • Analyze the protein percentages in common feedstuff Monogastric Nutrition • Pigs, as a general rule, eat to satisfy their energy requirements. • So, how much feed will a G-F pig eat? • Answer: about 5% of body weight. • Actual feed intake, as a percent of body weight, decreases as live weight increases. Monogastric Nutrition • What is the most common energy feed for swine in the Midwest? • Corn • What would be the second most common energy feed for swine? • Milo also referred to as grain sorghum. Monogastric • Cereal grains (corn, oats, wheat, etc) as a rule are deficient in protein or more specifically in amino acids. • Lysine requirement for a 40 lb. pig is approximately .95% of the diet. • Corn contains .25% lysine. Protein • Since swine diets consist primarily of cereal grains they need to be supplemented with a protein feed in order to enable optimum performance. Protein Feeds Other plant and animal proteins are often used in combination with SBM. • Fishmeal (60-70% CP) (Crude Protein) • Milk products, such as dried skimmed milk (33% CP) and dried whey (13.3% CP) • Meat and bone meal (50% CP) • Spray dried plasma protein and bloodmeal (86% CP) Feed Additives • Increase growth rate • Improve feed efficiency • Decrease mortality and morbidity caused by disease. • Improve the composition in the carcass (decrease fat content; increase lean content). Monogastric Fiber Diet • Swine producers often add fiber to the gestation diet just prior to farrowing and/or during lactation. • Bulky (high fiber) feeds such as oats, wheat bran or beet pulp are added to the ration to prevent constipation. Monogastric System Review • Evaluate the protein requirements and what is required of a non ruminant animal • State the nutritional requirements of non ruminant animals • Analyze the protein percentages in common feedstuff
