Why is dry matter intake important?

Maximising dry matter intake provides more nutrients to rumen microbes, which in turn provides more nutrients to the cow for milk production and composition, growth, reproduction and body condition. Every day, an efficient milking cow needs a dry matter intake equivalent to at least 3% of their body weight.

How is dry matter of animal feed determined?

To convert this nutrient analysis from “as fed” to “dry matter”: 1) Figure the dry matter percentage. Subtract the moisture content from 100%. In this example 100% - 75.9% = 24.1% dry matter.

What is dry matter requirement?

Dry matter intake is the amount of feed a cow consumes per day on a moisture-free basis. ... DMI is a factor that must be estimated before an animal's diet can be properly calculated; it establishes the amount of nutrients available to an animal for health and production.

How much dry matter does a cow need?

Daily intake on a dry matter basis may be 1.6% to 1.8% of her body weight. In comparison, corn silage will typically be about 70% TDN and lactating beef cows can easily consume 2.5% to 2.7% of their body weight on a dry matter basis of this feed.

What is dry matter in animal feed?

Dry Matter (DM): Dry matter represents everything contained in a feed sample except water; this includes protein, fiber, fat, minerals, etc. In practice, it is the total weight of feed minus the weight of water in the feed, expressed as a percentage.

What is the difference between as fed and dry matter basis?

Dry Matter is the value for a nutrient assuming all moisture is removed. Dry matter is mostly used by veterinarians because it yields specific information on a more uniform basis. As Fed would be the value for a nutrient without removing the moisture.

Why is dry matter moisture needed to be determined?

Knowing the moisture content of a feed ingredient is important because the moisture content affects the weight of the feed, but does not provide nutrient value to the animal. ... Increases or decreases in feed DM content result in over or under feeding of nutrients.

How is dry matter analysis calculated?

Subtract the dog food's moisture content percentage from 100%. Divide a nutrient's as-fed basis percentage by the difference you got from the previous step. Multiply this quotient by 100% to obtain the dry matter percentage of that nutrient.

How do you calculate as-fed from dry matter?

To convert weights from a dry matter to an as-fed basis, divide by the as-fed dry matter percentage value, expressed as a decimal. On an as-fed basis, a feedlot finishing ration is 60 percent DM. If the cattle consume 40 lb of the ration, how much actual DM is consumed?

Why is dry matter important for dairy cows?

In dairy cattle nutrition, any possible increase in dry matter intake (nutrients) is associated with higher milk yield. In general, and assuming a well-balanced ration is offered, an increase in dry matter intake of 1 kg per day results in about 2 kg extra milk.

Why is dry matter important in silage?

Generally the higher the dry matter the higher the potential intake of silage. However silages that are too dry can give rise to moulds and heating. Fermentation is described by pH, Ammonia and Lactic Acid - pH, normally 3.8 to 4.2, measures the silage acidity and so the ability of the silage to store.

Do cows lactate while pregnant?

Since cows only produce milk after they've been pregnant, farmers artificially inseminate them on what the industry calls a “rape rack.” Around 10 months after a cow becomes pregnant, she gives birth, and a strong bond instantly forms between mother and calf.

Which five factors will influence the dry matter intake of beef cattle?

Many factors affect dry matter intake, including animal weight, condition, stage of production, milk production level, environmental conditions, forage quality, and amount and type of forage or feed offered.

What is dry matter yield?

Dry matter means ( your yield without water content). Biological yiled means the green yield.

What is as feed basis?

As fed – This refers to feed as normally fed to animals. On an as fed basis, feed may contain from 90% water for lush pastures to 10% water for cereal grains. Dry matter – That part of a feed, which is not water. It is computed by determining the percentage of water and subtracting the water content from 100%.
