What is an example of feedstuff?
A wide variety of commodity-derived feedstuffs are used in ruminant animal production systems. Whole cottonseed, cottonseed hulls, cottonseed meal, soybean meal, soybean hulls, corn gluten feed, hominy feed, dried distillers grains, and rice mill feed are examples of commodity feedstuffs common in Mississippi.
What are the different classification of feedstuff?
2.1 Classes of Feeds by Composition and Usage
| Code | Class Description 1/ |
|---|---|
| 1 | Dry forages and roughages |
| 2 | Pasture, range plants, and forages fed green |
| 3 | Silages |
| 4 | Energy feeds |
What are the two categories of feedstuff?
The functions of a feedstuff can be divided into two categories. The first category is the feedstuff provides one or more of the six essential nutrients. The second category is the feedstuff modifies the characteristics of the diet such as improving palatability or rumen fermentation.
What is the purpose of feedstuff?
Introduction to feeds
| FEEDS: | Feeds are naturally occuring ingredients or materials fed to animals for the purpose of sustaining them. |
|---|---|
| FEEDSTUFFS: | A feedstuff is any product, of natural or artificial origin, that has nutritional value in the diet when properly prepared. |
What is feedstuff in agriculture?
feed, also called animal feed, food grown or developed for livestock and poultry. Modern feeds are produced by carefully selecting and blending ingredients to provide highly nutritional diets that both maintain the health of the animals and increase the quality of such end products as meat, milk, or eggs.
What are the eight classes of feedstuff?
Feedstuff Classification
- Dry forages & roughages.
- Pasture, range plants, fresh forage.
- Silages (and Haylages)
- Energy feeds.
- Protein supplements.
- Mineral supplements.
- Vitamin supplements.
- Non-Nutritive Additives.
What are the 8 classes of feedstuff?
What is the importance of knowing the nutrient composition of a certain feedstuff?
When planning a supplementary feeding program and choosing feeds it is important to know the nutrient composition of those feeds so that nutritional requirements for target animals can be met. Energy requirements are expressed as megajoules (MJ) of metabolisable energy (ME).
How do we determine the value of a feedstuff?
To calculate the amount of a feed you need to deliver to your livestock, you must convert the proportions in the feedstuff into pounds of nutrients contained in a certain weight of feedstuff (for this publication, we will use the unit weight of sale; that is, pounds or bushels as appropriate).
How do you read a cattle hay analysis?
Typically, the greater the value, the more energy-dense the forage is considered. Low-quality hay is generally 45 to 52% TDN. Mid-quality hay is generally 52% to 58% TDN, and high-quality hay is greater than or equal to 58% TDN.
What is NFC in hay?
Non‐fiber Carbohydrate (NFC). Although not always perfect, the NFC value is often used as an indicator of the level of starches and sugar in a forage sample. Fructan, a complex sugar, is known to trigger laminitis, a debilitating disease in horses.
What is ADF in hay?
ADF is a measure of the plant components in forages that are the least digestible by livestock, including cellulose and lignin. ADF increases digestibility decreases, so forages with high ADF concentrations are typically lower in energy.
What is ESC in hay analysis?
ESC measures those that can be extracted by dissolving the sample in 80-percent ethanol and is a subset of WSC that doesn’t include fructan. By subtracting ESC from WSC, you get an estimate of fructans in the sample.
What is ESC in horse feed?
Here are the primary terms used to describe carbohydrates in feeds: – Ethanol Soluble Carbohydrate (ESC): This is the sugar (simple and some complex) content of the feed. – Water Soluble Carbohydrate (WSC): This is the ESC + the fructans in the feed.
What is NDF in hay?
NDF is a measure of insoluble fiber. In theory, the higher the NDF, the less a horse will eat. NDF levels under 65 percent are generally good for horses. Horses likely won’t eat hay with NDF values over 65.
What is NSC content in horse feed?
NSC stands for “non-structural carbohydrates”, which is mostly referring to the levels of sugar and starch in a commercial grain horse feed. The topic of NSC comes up frequently when discussing low-carb, low-starch diets for horses. Performance horses rely on sugar, starch and fat for energy.
What is WSC in horse feed?
Water Soluble Carbohydrates
Water Soluble Carbohydrates (WSC) – This includes ethanol soluble carbohydrates (ESC) which are primarily sugars, both monosaccharides and disaccharides. WSC will include various oligosaccharides and polysaccharides. Fructans in forages are included in the WSC.
What is a feedstuff?
The first category is the feedstuff provides one or more of the six essential nutrients. The second category is the feedstuff modifies the characteristics of the diet such as improving palatability or rumen fermentation. An example of a feedstuff that serves at least one function in each of the two categories is alfalfa hay.
How are feedstuffs classified in the United States?
In the U.S., feedstuffs are classified according to two classification systems. The first system is the International Feed Identification System. The International Feed Identification System classifies feedstuffs based on the primary nutrient provided by the feedstuff. The system classifies a feedstuff into one of eight classes.
How should the nutrient profile of the feedstuff be determined?
The nutrient profile of the resultant ration should closely match the nutrient profile of the animal’s requirements. Cost of the feedstuff will be analyzed based on cost per unit of nutrient provided by the feedstuff.
What are the factors that influence the selection of feedstuffs?
The two primary factors influencing the selection of feedstuffs and relative proportion of feedstuffs in a ration are nutrient content of a feedstuff and cost of the feedstuff. The nutrient profile of the resultant ration should closely match the nutrient profile of the animal’s requirements.
