What is the difference between roughage and concentrates

Roughage is portion of 'food obtained' from plants. Roughage does not provide any nutrient content. Concentrates: Concentrates provide the livestock with carbohydrates and its main 'purpose' is to 'fatten' the animals.

Concentrates are nutrients that can be easily digested. Concentrates contain low levels of fibres and high levels of 'proteins' and other 'nutrients'. ChowChow 2 weeks ago 0 javaab.

NDF contains hemicellulose, cellulose, and lignin. Figure 8. The plant cell contents also contribute to the roughage. The cell contents include such components as nonfibrous carbohydrates, proteins, and lipids. The nonfibrous carbohydrate content is comprised of simple sugars i. The protein component in forages is comprised of both true protein and nonprotein nitrogen compounds. In general, the protein content of legumes is greater than the content of grasses.

The mineral content of roughages is influenced by roughage and mineral content of the soil. In general, compared to concentrates, roughages are higher in calcium, potassium, and microminerals and moderate to low in phosphorus. Legumes have a higher calcium and magnesium contents compared to grasses. Regarding vitamins, compared to concentrates, roughages are higher in fat-soluble vitamins. Roughages are also a good source of the B-complex vitamins.

The nutritional value of roughages varies. In addition to other factors such as plant species, the nutritional value of roughages depends on the proportion of cell contents to cell wall components and on the extent of cell wall lignification. Most roughages can be effectively incorporated into at least one type of ration.

Effective use of a roughage requires matching nutrient requirements of an animal with the nutritional value of a roughage. Effective use of a roughage also requires appropriate processing and supplementation. As stated earlier, in ruminants, enzymes from rumen microorganisms are required for the digestion of roughages. As the population of rumen microorganisms is dependent upon the feedstuffs consumed, the composition of the diet influences the extent and rate of digestion of roughages.

Feeding of high-energy feedstuffs has a negative associative effect on the degree of utilization of a roughage. Dry roughages include hay, straw, and artificially dehydrated forage. Silages include grass, alfalfa, sorghum, and corn. Thua, roughage can mainly be pastures or legumes. The concentrate is another type of animal feed. It is rich in carbohydrates, proteins and digestible nutrient content. But it has a low amount of fibre. Basically, concentrate consists of fat, cereal grains and their by-products barley, corn, oats, rye, wheat , high-protein oil meals or cakes soybean, canola, cottonseed, peanut , and by-products from the processing of sugar beets, sugarcane, animals, and fish.

Due to this composition, concentrate provides more energy to animals. The main purpose of concentrate is to fatten animals. Roughage is rich in fibre and low in total digestible nutrients. In contrast, the concentrate is low in fibre content and high in total digestible nutrients. So, this is the key difference between roughage and concentrate.

Furthermore, roughage contains a low amount of proteins while concentrate has more proteins and protein by-products. When considering the composition, roughage consists of pasture forages, hays, silages, and byproduct feeds that contain a high percentage of fiber. On the other hand, concentrate consists of grains and molasses, protein and energy-rich supplements and byproduct feeds, vitamin supplements, and mineral supplements.
