One study in over 62, women found that those who ate at least 20 grams of fiber daily were much less likely to experience constipation than those who ate only 7 grams or less per day Another study in 51 people looked into the effects of eating fiber on constipation.
Every day for 3 weeks, participants ate grams of bread — either rye or white. The rye bread contained 30 grams of fiber, while the white bread contained 10 grams.
Dietary fiber also act as a prebiotic , which feeds the beneficial probiotic bacteria in your gut, enabling them to thrive and limit the growth of harmful bacteria.
The prebiotics in fiber may also reduce your risk of colon cancer by promoting healthy bowel movements and strengthening the layer of tissue lining your intestines Consuming fiber may also help you reach and maintain a healthy weight.
In one study, 28 adults increased their fiber intake from 16 to 28 grams per day. They followed one of two high-fiber diets daily for four weeks — either 1.
On both high-fiber diets, participants ate about fewer calories per day and lost about 3 pounds 1. At the same time, they reported higher levels of fullness and less hunger than before they started the high-fiber diet Eating more fiber may also increase your resting metabolic rate RMR , which is the number of calories you burn at rest.
A 6-week study in 81 adults found that those who ate a diet containing about 40 grams of fiber daily had a higher RMR and burned 92 more calories per day, compared to those who ate a diet with only about 21 grams of fiber per day In addition, many high-fiber foods, such as whole fruits and vegetables, are low in calories. Try eating more of these foods to feel full and satisfied. They will help keep your calorie intake low, which may promote weight loss.
High-fiber foods help slow digestion, which may help stabilize your blood sugar levels by slowing the absorption of sugar into your bloodstream 21 , In fact, some studies have shown that fiber may help regulate blood sugar and insulin levels. Insulin is a hormone that helps transport blood sugar into your cells and directs your body to burn it for energy or store it as fat Keeping blood sugar levels moderate is important, as spikes in blood sugar can damage your body over time and may lead to diseases like diabetes One study in 19 people with type 2 diabetes looked into the effects of eating a fiber-rich breakfast on blood sugar levels.
Those who ate a high-fiber breakfast that included 9—10 grams of fiber had significantly lower post-meal blood sugar than those who consumed a low-fiber breakfast containing only 2—3 grams of fiber Maintaining low insulin levels may also help you lose weight by decreasing the number of calories your body stores as fat Dietary fiber may help lower high cholesterol and blood pressure levels, both of which are risk factors for heart disease.
All these play active role in the digestion of feed by ruminant animals , especially the rum en. Roughages are best utilized by ruminant animals ; r oughages main tain the struct ure , ac tivities and micr obial p opulation in the digestive tract of a ruminant animal. A minimu m level of roughage is necessary to keep the r umen functioning as it should be; By the virtue of the complex nature of the ruminants, they can gleefully utilize roughages ; b ut not all ruminant animals, only the older ones with matured rume n ; serving young animals roughage is like giving them poison, it is best they do not eat than eating roughages because it will inflict upon them pains like sore in the mouth.
Their digestive system is not f ully ma tured and cannot utilize roughages well. Serving them concentrate feed at this stage is the best. The sp ecie of the ruminant de termines the amount of ro ug hage to be added in the ani mal feed.
What makes roughages digestible is the ru men; animals with la rge volume of the rume n, like cattle, require large r amount of rou ghages. Roughages are either fed in a fresh, dried or ensiled state. Also , the mineral content of roughages is greatly influence d by the mineral c omposition of the sown soil ; roug hages are hig her in fat soluble vitamins and are also good source of B -comple x vitamin. Unlike other livestock animals , rumina nt s have the ability to de grade the fibres in plants and metabolize them to pr oduce meat and milk that are consumed by humans.
Minimal NDF values have been studied on cattle, especially dairy cows, very extensively. For sheep, goats, and deer, I can only speculate the minimum NDF. When animals in a native pasture select forages each day, they have the ability to manipulate their diet. If they eat something that tends to make their rumen more acidic, they can then search for another forage higher in fiber content to balance out the diet.
And most of what they eat will be of the long roughage category. And most of the prepared feeds are ground to some extent to either increase digestibility, or to prevent the stock from picking out just what they like in the ration.
So, when feeding your ruminants in the pen, be aware of the fiber levels. However, you can use it to determine if the feed has enough fiber in it. The higher the crude fiber value, the more roughage should be in the ration. However, be sure this fiber is coming from roughage sources such as cottonseed hulls. Check to see how much roughage is in the feed.
Be wary of feeds like that. You could have some digestive problems arise. 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. A negative associative effect occurs when the addition of one feedstuff negatively influences the utilization of another feedstuff. One of the primary species responsible for the digestion of roughages is cellulolytic.
The primary end-product of digestion is the acetate. Acetate is a relatively weak acid.
