What makes a more feed efficient dairy cow?
What makes a more feed efficient dairy cow? Cows with reduced maintenance needs and better energy efficiency may eventually lead to less feed use in the dairy industry, says researcher. An ongoing research project funded by a grant from the US Department of Agriculture (USDA) and involving several universities and almost 7,000 cows has been ...
How much feed should you feed a cow?
While there might be a slight variation, the grain amount you should start with is 1.10 lbs per head per day. Stick to this amount until all the cows that are being fed actually eat the grain. Once you’re satisfied with how much grain the cows eat, you can slowly up the grain level by 1.10 lbs every second day until you reach the desired ration.
What does a dairy cow need to eat?

What can I feed my dairy cow to increase milk production?
Diets for dairy cows should contain both rumen degraded protein and rumen undegraded protein, at an ideal ratio of 65:35. Usually, reliance on feed proteins with a high content of digestible RUP is greatest in high-producing cows when most or all of the forage is provided by high-quality grasses and legumes.
What do they feed dairy cows?
Grass: More than 50 percent of cow feed is actually grass (farmers call it hay and silage). While people often think dairy cows are fed a high-grain diet, in reality they eat the leaves and stems from corn, wheat and oats far more often than they are eating grain, like corn kernels.
What is the most important nutrient for dairy cattle?
Water. Water is second only to oxygen as the most important element for life. 24 Milk is 87% water and is critical for milk production. Water makes up between 56% and 81% of total body weight in the dairy cow25 and between 68% and 72% in the preruminant calf.
What nutrients do dairy cows need?
Select vitamin and mineral recommendation are:Salt: Cows need 3 to 4 oz of salt per day. ... Calcium: more than 150 grams/day or . ... Phosphorus: about 100 grams or 0.35 to 0.4 percent of ration dry matter.Magnesium: 0.3 to 0.4 percent of ration dry matter.Potassium: 1.0 to 1.5 percent of ration dry matter.More items...
What is the best food for milking cows?
Cereal grains (barley, corn, sorghum, rice, wheat) are the typical "high energy" feeds for dairy cows, but they are low in protein. Rolled or cracked cereal grains are excellent sources of readily fermentable carbohydrates (starch) which increase the concentration of energy when included in the diet.
How much should a dairy cow eat per day?
A dairy cow should be given 15-20 kg of chopped forage per day, preferably in two splits i.e. one in the morning and the other in the evening.
How much grain should I feed my dairy cow?
Grain fed (DM basis) to milk yield on a lb to lb basis. The recommendation is to feed about 1 lb of concentrate per 4 lb milk production with a maximum of 16 to 20 lb/cow/day. For late lactation cows, we suggest a 1:5 or 1:6 grain to milk ratio.
What kind of food should be given to milk producing animals?
Answer. dry forages for pasture (fresh forage) or high quality Alfafa hay, Alfalfa grass mixed with hay, grass hay or straw, silage etc.
How much protein does a dairy cow need per day?
A guideline is to feed 0.5 kg of a 34 to 50% protein concentrates for every 5 kg of milk produced above 20 kg of milk. 2- If concentrates are being fed separately from forages, they should be fed several times a day.

Why is it important to monitor dry matter concentrations of moist feeds?
This is because diets are formulated based on the nutrient concentrations of the feeds on a dry-matter basis, but the ingredients are mixed based on their moist weight.
What are the disadvantages of starch?
A major disadvantage is that starch and other nonfiber carbohydrates are generally provided in a small number of meals per day, typically at milking time. Thus, there is the possibility for large fluctuations in rumen pH, which may impair fiber digestion and contribute to poor rumen health.
What is lead factor in lactating cows?
Diets for lactating cow groups should be formulated with a lead factor, meaning the diet should be balanced for more milk production than the average of the group. This is to ensure that the nutrient requirements of the higher-producing cows in the group are met.
What are the disadvantages of component feeding systems?
In addition to the potential for fluctuations in rumen pH, another disadvantage of component feeding systems is the inability to monitor forage intake. This is because there is no direct need to weigh the amount of forage offered if it is not being mixed with other diet components.
Why is dry matter consumption in pasture systems important?
Dry matter consumption in pasture systems may limit nutrient intake because maximal consumption rates are lower than in confinement systems. This will limit energy intake, thus requiring supplemental energy sources to be fed to achieve high milk production.
What is the milk production rate in pasture?
Milk production rates in unsupplemented pasture feeding situations are seldom >25 kg/day. Energy supplements may include starches such as cereal grains or highly fermentable fiber sources such as grain byproducts. Protein, and particularly sources of RUP, may also need to be supplemented.
How much should orts be fed?
To assure optimal feed availability, orts should be 2%–4% of the total amount fed. Particle length of the orts should be measured to assure that sorting of the feed, which usually results in large particles being left behind, is not occurring.
How much bunk space do cows need?
Lactating cows need 24 inches of bunk space. Close-up and recently fresh cows should have 30 inches of bunk. If feed is available at all times cows can get by with 18 inches of bunk space. Cows eat best in the grazing positions and the bunk surface should be smooth.
How to calculate reference cow?
To calculate reference cow, take the average peak milk of older cows and add the daily average of all cows and divide by 2. Two groups: Balance rations at 20 percent above average milk production of each group. Three or more groups: Balance rations at 10 to 15 percent above average milk production of each group.
What is ration analysis?
Ration analysis. A ration analysis reviews the nutrients that each feed adds to the ration. It doesn’t balance the ration and doesn’t correct any nutrient deficiencies or excesses. For an accurate analysis, you must know how much of each feed you give, including the nutrient content.
What is the basis of a cow's diet?
Formulating rations provides cows with the nutrients they need to stay healthy and optimize production. The basis of a cow’s diet should be high-quality forage. Acid neutral detergent fiber should be at least 18 percent and neutral detergent fiber at least 28 percent of ration dry matter. Balance rations to meet the nutrient requirements ...
What is ruminant feed pyramid?
The ruminant feed pyramid provides the basis for formulating rations. High-quality forages and grains are the base of all diets and will support good milk production. Added fats, rumen undegradable protein and other feed additives are needed by higher producing cows. The goal of your feeding program should be:
What is the least cost function?
A least cost function. Milk price information. A maximum profit (income over feed cost) for one of the constraints or specifications to formulate on. In maximum profit, the computer selects feeds and calculates a milk production level to obtain maximum profit.
Can lactation cause ketosis?
Early lactation cows fed too high forage and low energy of rations may be more prone to ketosis and have rapid body weight loss. A deficiency of fiber can result in: Acidosis, cows going off-feed and fluctuating dry matter intake. Low milk fat percent.
Why should high moisture grains be fed rolled versus whole?
High-moisture grains should be fed rolled versus whole to optimize starch utilization by the rumen bacteria. Heating grains, such as steam flaking (24 to 28 pounds/bushel), enhances starch digestion.
Why is high moisture corn important?
Proper preparation of high moisture grains is necessary to prevent sorting of ear corn during ensiling (cobs and grain), to increase digestibility of the grain and the entire ration, and to minimize sorting during feeding. Ensiled grains may be prepared more coarsely than dried grains. Starch in high moisture grains is more soluble and degrades more quickly in the rumen than starches in dry grains. This can be offset by somewhat coarser preparation.
Why should dairy cattle be fed rations?
Due to palatability problems with rye, triticale, and wheat, limited amounts should be fed in rations for dairy cattle (Table 1). The energy that cereal grains supply comes in the form of mainly starch with minimal levels of fats and sugars.
Why is palatability important?
Palatability of grain mixes or commodities is important for attaining the required levels of feed intake. Proper processing, storage, and attention to particle size are important for palatability and ruminal degradation of nutrients. The manner of feeding and the processing method can influence intakes.
How does steam flaking affect rumen?
Steam-flaked grains should be rolled to a thin flake. The heating process gelatinizes the starch in a manner that increases fermentability in the rumen.
What is the primary source of energy in dairy rations?
Starch is the primary source of energy in dairy rations. The source and processing method of the starch will determine how it will be digested in the rumen. Cereal grains like corn provide most of the starch in dairy cattle diets.
Why do dairy cows eat starch?
Most often they are fed to raise the energy level of the ration for dairy cattle and to compensate for any other deficiencies that remain beyond those provided by the forage portion of the ration. Energy sources for dairy cattle can be broken down into starch, sugar, and fat.
