Feedstuff(s) Usage/Purpose In order to understand proper feeding and usage of feeds & feedstuffs, it is necessary to comprehend: animal digestion systems animal growth patterns
Feedstuff(s) Usage/Purpose In order to understand proper feeding and usage of feeds & feedstuffs, it is necessary to comprehend digestion systems & growth patterns. Two types of digestive systems (non-ruminant/monogastric & ruminant). Ruminant animals (such as cattle, sheep, etc) have multi-part stomachs. This results in fermentation, and thus the digestion of grass/forage plants for the utilization/absorption of nutrients is possible and effective. Non-ruminant or mongastric animals (such as pigs) have a simple or single compartment stomach, so grass/forage digestion/utilization is not efficient. Animals first grow by building bone & muscle. As they age, bone & muscle growth decrease, & b ody maintenance/fat deposition needs increase. As result, protein is important in younger animals & energy is important in older/finishing animals.
Nutrients of Feeds/Feedstuffs All feedstuffs contain many different nutrients All nutrients are important to animal Each nutrient serves a different purpose There are five types of nutrients energy (carbohydrates & fats) proteinvitaminsmineralswater
Purposes of Nutrients Energy…used to fuel, power, and heat the body carbohydrates – sugars and starches fats – 2.5 times more energy than carbohydrates Protein…used to build the body (bone, muscle, tissue, etc) Vitamins…important for chemical reactions in the body Minerals…needed for the various life processes of body Water…is the largest component of most living things, as result, it is the most important/needed nutrient
Feedstuff(s) Categories Feedstuffs can be divided into two major categories: Concentrates….grains such as corn, oats, wheat, barley, milo, soybeans, etc….provide much energy…the protein varies, soybean meal and cottonseed meal is high (41-44%) but corn and oats is lower (9-12%) Roughages….forages such various types of hay, alfalfa, clover, etc….provide much fiber…the protein content varies, alfalfa is higher (15-19%, and sometimes even a little higher) but grass hay is lower (6-8%).
Feed Supplements Along with the two major divisions of feedstuffs, other ingredients are also used when formulating a feed ration Typically, there are two other types of ingredients: Nutrition Supplement…a mixture of vitamins and minerals designed to ensure proper nutrition and balance that meets/exceeds minimum requirements Medical Supplement…provides some sort of treatment and/or prevention through the animal eating/consuming the feed ration provided

Feedstuff(s) Quality Regardless of the feedstuff (concentrate or roughage), the quality of the ingredient is of utmost importance. Quality can be assessed by: color…is it the proper color odor…does it smell correctly/pleasant visual…are foreign objects present If is has wrong color, has unpleasant odor, contains mold, contains other objects/weeds, etc…the quality is low
Hay Quality The quality of hay can be assessed/evaluated via: Maturity (stems/seed heads) Spoilage (moldy/dusty) Heat (odorous/dark color) Content (objects/weeds) Color (greenish) Freshness (smells good)

Other Items There are many other items that could have been included in this presentation; and maybe some of them should have been included, and maybe some of those that were included should have been excluded. Regardless of your thoughts and opinions concerning the inclusion/exclusion of the various items, it can be agreed that consensus would be difficult to achieve.
Other Items Given the thoughts stated on the previous slide, it is recommended that additional items be identified for additional review and study. Conducting an internet search for animal feeds, animal nutrition, forages, hay, pasture, or specific types of grains (barley, corn, milo/sorghum, oats, soybean, wheat, etc) is an excellent starting point.
