What is NDF in fodder?

What is NDF in fodder?

Neutral detergent fiber (NDF) is the most common measure of fiber used for animal feed analysis, but it does not represent a unique class of chemical compounds. NDF measures most of the structural components in plant cells (i.e. lignin, hemicellulose and cellulose), but not pectin.

Can sorghum be used for silage?

Forage sorghum is best utilized as a silage crop, although it can be grazed or cut for hay if managed appropriately. Harvesting at moisture contents higher than 72 percent may cause problems during the ensiling process and will decrease intake by cattle. Harvesting drier sorghum can reduce the energy and protein value.

Is sorghum good for fodder?

Sorghum is rich in energy but has low protein content making it necessary to supplement with high protein fodder like sweet potato vines. The vines are well adapted to dry highlands and may be grown in the farm. They increase sorghum silage intake leading to increased milk production.

Which of the following is multicut forage sorghum variety?


S. No. Crop/Variety Green fodder yield (t/ha)
1. Sorghum CO 27 (60-65 days) ( Sorghum bicolor) 35-40
2. Multicut fodder sorghum CO (FS) 29 170 (6-7 cuts)
3. Multicut fodder sorghum CO 31 190 (6-7 cuts)
4. Pearl millet CO 8 (50-55 days) (Pennisetum glaucum) 30

What is ADF NDF?

The abbreviations “ADF” and “NDF” stand for “acid detergent fiber” and “neutral detergent fiber,” respectively. They are measures of feeds’ cell walls, or structural carbohydrate components.

How is NDF calculated?

A non-deliverable forward (NDF) is a cash-settled, and usually short-term, forward contract. The profit or loss is calculated on the notional amount of the agreement by taking the difference between the agreed-upon rate and the spot rate at the time of settlement.

Will sorghum regrow after cutting?

It develops fibrous roots, but no rhizomes. Each plant can produce many tillers and will regrow rapidly after cutting, allowing for two to three cuttings for the season. Stems and leaves of forage sorghum plants grow 8 to 12 feet tall and are large in diameter, like corn.

Is sorghum silage good for cattle?

Following good rain earlier in summer, sorghum silages have been around 45-55 per cent dry matter, 9-12pc crude protein and 8-10 megajoules of metabolisable energy on a DM basis. Silage can be used as the major feedstuff for growing steer calves from 150-350kg for daily gains of 0.5-1kg.

What animals eat sorghum?

In animal nutrition, grain sorghum is mostly used as an energy source and is a good feedstuff for poultry, pigs and ruminants. The stalks remaining after harvest can be grazed as some varieties stay green for a long period of time.

What are the uses of sorghum?

Sorghum crop is known for multiple uses as food, feed, fodder, and fuel. In addition to these, many other industrial applications such as health, pharmaceutical diagnosis, packing, synthesis of organic molecules, and utility items have been in place. Sorghum is also employed as pet feed for dogs, fish, etc.

What is the seed rate of sorghum?

Seed rate of 35-40 kg per hectare is well enough and sowing should be carried out by drilling @ row-to-row distance of 25 cm.

How many bushels of sorghum can you get per acre?

Its ability to withstand short periods of drought and high temperatures allowed the crop to produce a good yield across many areas. The final average expected yield across the U.S. will be around 76 bushels per acre, which is just below the record set in 2016 at 77.9 bushels per acre.

What is a good NDF?

Generally, NDF content of 40-50% and ADF content of 30-35% is considered ideal for performance horses, young stock, and broodmares.

How do you calculate NDF?

The ADF percentage is measured by boiling forage in an acid detergent solution, then measuring the residue remaining. In the same way, NDF is measured by boiling the forage in a neutral detergent solution, then measuring the insoluble residue.

What is ADF and NDF?

Neutral Detergent Fiber (NDF): Structural components of the plant, specifically cell wall. Acid Detergent Fiber (ADF): The least digestible plant components, including cellulose and lignin. ADF values are inversely related to digestibility, so forages with low ADF concentrations are ususally higher in energy.

How are NDF priced?

Most NDFs are priced according to an interest rate parity formula. NDF prices may also bypass consideration of interest rate factors and simply be based on the projected spot exchange rate for the contract settlement date.

Does sorghum kill winter?

Sorghum and sudangrass plants contain a compound called dhurrin, which can break down to release prussic acid (hydrogen cyanide, HCN). Sudangrass has low levels of this compound and rarely kills animals.

How deep do sorghum roots grow?

Mature Root Habit of Folger Sorghum. Some roots reached depths of 3 feet. At maturity, the surface soil was much more thoroughly occupied, often to the ground line; the working depth was also greater, some roots extending to the 3.5-foot level.

Is sorghum bad for cattle?

Sudangrass and sorghum are two of a group of plants that produce cyanide, which can poison livestock under certain conditions. These plants, called cyanogenetic plants, produce cyanogenetic glucosides during their growing stage.

Can sorghum be fed to cattle?

Sorghum, both grain and forage, is an important feedstuff for livestock. Sorghum grain can be utilized in the rations of beef cattle as a replacement for corn. Although, research has shown sor- ghum grain to be comparable to corn in beef finishing diets, the market often values sorghum less than corn.

What is the difference between grain sorghum and sorghum?

Grain sorghum grows to about 5 feet and is used for livestock feed, biofuels, pet food and human consumption. Forage sorghum grows 6 to 12 feet tall and produces more dry matter tonnage than grain sorghum. Because of its coarse stem, it’s primarily used for silage.

Is sorghum a fodder crop?

Fodder sorghum – Cholam / Jowar It is cultivated mainly for grain and also for fodder. Sorghum is a drought resistant annual crop.

Is the variety of sorghum for grain and fodder purpose?

Sorghum as Fodder/Feed Some varieties of sorghum are dual purpose and are grown for both grain and forage. Sorghum grain are used as poultry diet whereas forage sorghum is used for livestock.

A. The abbreviations “ADF” and “NDF” stand for “acid detergent fiber” and “neutral detergent fiber,” respectively. They are measures of feeds’ cell walls, or structural carbohydrate components.

Why is sorghum bad for you?

The biggest health risk of sorghum is tied to its potential as an allergen. Allergies associated with grasses and grass pollen are extremely common. Unfortunately, Sorghum is a grass and is known to produce an allergic reaction in some people.

Can sorghum kill you?

Individuals can suffocate to death in a grain bin or silo when engulfed in grain while working or playing. The most common grain injuries and death occur by entrapment of sorghum, cottonseed, livestock feed and yellow corn. When the grain gives way, it causes the worker to fall and become engulfed.

Which crop is called Queen of forages?

Alfalfa (Medicago sativa L.) or lucerne is the most important forage legume worldwide and frequently called the ‘Queen of forages’ due to its wide adaptation, high yield, and high quality.

How many types of sorghum are there?

Sorghum is a genus of about 25 species of flowering plants in the grass family (Poaceae). Some of these species are grown as cereals for human consumption and some in pastures for animals. One species, Sorghum bicolor, was originally domesticated in Africa and has since spread throughout the globe.

What is the origin of sorghum?

Sorghum originated in the north-eastern quadrant of Africa, where the greatest variability in wild and cultivated species is found to this day. It was probably domesticated in Ethiopia by selection from wild sorghum between 5,000 and 7,000 years ago.

How does NDF affect the quality of forage?

First it is very important to remember that total NDF content of the forage is still a dominant factor in determining overall forage quality. For example a forage that contains 40% NDF is generally of higher quality than a forage that contains 60% NDF. Differences in NDF digestibility between common forage species are presented in Figure 1.

What are the different types of sorghum forage?

E. Variety Selection: Species Variety Yield (T/acre) Forage quality Forage quality Species Variety Yield (T/acre) CP (%) NDF (%) Dent corn Pioneer 3732 9.4 6.7 41.3 Sorghum Sweetreat 9.5 5.2 44.7 Sorghum Sorgo 10 7.6 7.1 52.1

How is NDF digestibility used in the dairy industry?

A prediction of NDF digestibility is required to use a summative energy prediction for forages. This Focus on Forage will discuss the concepts and methods of NDF digestibility and how it is being used in the dairy industry. How is NDF digestibility measured?

When does NDF digestibility decrease in a legume?

In legumes, NDF digestibility decreases slowly during the first stages of growth (stem elongation). However, when cell and stem diameters increase and the heavily lignified xylem tissue develops, NDF digestibility decreases rapidly. The maturity mechanisms in legumes that reduce NDF digestibility are similar in grasses and corn silage.

What’s the difference between high NDF and low NDF forage?

For example, a forage that contains 40% NDF is generally of higher quality than a forage that contains 60% NDF. Differences in NDF digestibility between common forage species are presented in Figure 1. In general legumes have less total NDF and lower NDF digestibility due to greater lignification as compared to grasses.

What are the ADF values for sorghum sudangrass?

However, with lower crude proteins, we probably improved nitrogen utilization of the milking herd. The acid detergent fiber (ADF) values of the grasses were very similar and are within the range of low 30s to mid-50s.

Why are forages being evaluated for NDF digestibility?

There are several important reasons why forages are being evaluated for NDF digestibility. First, research has demonstrated that lactating dairy cows will eat more dry matter (DM) and produce more milk when fed forages that have higher NDF digestibility.
