Provide 18-19% crude protein in your top cow ration. • Where grass quality and/or grazing conditions are poor, feeding 2-3kg of concentrates helps maintain milk yield and consequently lactose levels. Even if this cow consumes at only 2.0% of her body weight in DM (26.0 lbs) she will still eat 2.47 lbs of CP and 13.5 lbs of TDN/day. A basic ration is fed to all dry cows, and a little extra energy and protein are added and fed to the close-up herd during the last two weeks before calving. Because of the price of distillers' grains and residue in 2014, the spring calving system that includes feeding a ration of residue and distillers is the least expensive system in our comparison. There are numerous examples of a good transition diet adding 1000 litres to the subsequent lactation. The cow’s system monitors the fat intake in the blood, and when fat levels reach certain levels, it will cause the cow to reduce her fat intake.

A ration based on grass hay, greenfeed or cereal silage should be supplemented with a 2:1 mineral (containing two parts of calcium to one part of phosphorus). The use of imperial measurements represents the industry standards. If low quality forage (e.g. University of Guelph researchers added about 10 percentage points of moisture to create a 45.4% DM for the ration. Conclusion. Avoid low or high calcium intakes, meet magnesium, potassium, and selenium requirements. • Dry the herd off when production averages less less than 8-9 litres. Provide a minimum of 30 inches of bunk space per cow. For example, 100 lb. Ration 3 … Maximum intake of NDF in the total ration should equal 1.2% of the cow's body weight (1.3% for a high-producing cow). Ration 1 below has been used successfully for cows of average milking ability at the NDSU Carrington Research Extension Center Livestock Unit. The addition of anionic salts to the close-up dry cow grain ration will also stimulate the release of reserve calcium from bone. Ration 2 resulted in a few more open cows than Ration 1, but cow and calf growth were satisfactory. This factsheet presents options for reducing feeding costs while supplying a healthy ration to the cow. This factsheet is written using common units used by the beef industry. Estimate the amount of feed to be fed to the cow per day. General feeding guidelines, maximum amount of fat from source: Animal fat - 1.0 lb/cow/day Plant/vegetable - 1.2 lb/cow/day Inert fats - 1.0 lb/cow/day 3. Reduced veterinary costs for treating metabolic disorders and higher milk production more than offset the increased cost of a single dry cow ration. If you are spending a lot of time and money addressing transition cow and metabolic problems, a single dry cow TMR is worth discussing with your herd management team. Calculate the nutrients supplied by the substituted ration and compare to the cow's nutrient need. ... simple dry-cow feeding strategy. For large-breed dairy cows, this results in a sodium requirement of ~9–10 g/day. Estimating potential intake from NDF. Feeding dry cows through transition has a massive effect on herd health, fertility, milk output and overall farm profitability. • … 2. Maximum NDF intake from forage should equal 1% of the cow´s body weight. Increase the moisture content of high-straw dry cow diets. Dry cows that are not grouped and offered one TMR may be fed limited amounts of the milk cow TMR two or three weeks prior to freshening. The Pearson square ration formulation procedure is designed for simple rations. 1. For example, if there is cottonseed in the milking cow ration, there should be some cottonseed in the close-up or transition ration. Avoiding Ration Ingredients or Levels of Ration Ingredients that Decrease Dry Matter Intake Fat: High levels of fat (over 7.5% total fat) can inhibit dry matter intake. Table 1.

Feed efficiency in the simplest terms is the pounds of milk produced per pound of dry matter consumed. Forage Strategies. Nonetheless, a ration of only “good” grass hay (24 lbs) can meet the pregnant cow’s needs, while mature grass hay needs to be fed with a small amount of supplemental protein (1-2 lbs). per day and about 15 to 20 kg of green fodder. In formulating a ration for dairy cows to achieve high levels of milk production, one should aim at providing a diet that contains all nutrients required by farm animals. A key component of the one-ration approach is replacing a portion of the ration's forage component with non-forage fibre sources (NFFS). ADVERTISEMENTS: 2. Ammonium chloride and magnesium sulphate are examples of anionic salts. ADVERTISEMENTS: Feeding Schedule: Dry Cows and Recent Calvers (Rodricks, 1997) 1. If a feed does not fit in the lactating ration, perhaps it can fit into the heifer or dry cow ration and spare more suitable feeds for lactating cows. of straw in a 24 hour period but the microbes in the rumen can only digest about 1.25 per cent of the cow's body weight as dry matter straw. Dairy cow rations are formulated on a dry matter basis. Implementing the balanced ration 4. A fresh cow needs 56 g of cell level calcium per day for 40 kg milk production. Intake of Dry Matter According to the size of the cow in the main, and other conditions to a lesser extent, it can consume a certain amount of dry matter. of water and 10 lb. Example: 600 kg cow X 4% = 24 kg dry matter. Ration 1 below has been used successfully for cows of average milking ability at the NDSU Carrington Research Extension Center Livestock Unit. Nutritionist's Comments: The common recommendation is to provide an ration with nutrient density intermediate between the far-off dry cow ration (0.59 Mcal or megacalories per pound of dry matter) and the high cow ration (0.79 Mcal per pound dry matter). Strive for a well-blended, uniform consistency. Typically this is a ration that is fed in the dry period, as the energy needs of the cow are relatively low in this period. Knowing the correct dry matter (100 - percent moisture) of ensiled forages and wet grains and feeds fed in the TMR is key to mixing and feeding a balanced ration. The ration contains 8.5 kg of dry matter from Napier grass. If the cow is a heifer, we want her to grow and be a productive cow in her maturity. All cows in the pen should be able to eat at once. Straw: 6.3-6.7: 0.6-1.0: 20%+ Not suitable as milking cow feed but can make part of a dry cow ration. In order for the square to work, follow specific directions for its use. The amounts of each feed fed are on an as is or as fed basis. a dry diet.

Nutrient contents of ingredients and nutrient requirements must be expressed on the same basis (i.e., dry-matter or as-fed). Bypass (undegradable) protein should be 35-40% of crude protein. In formulating a ration for dairy cows to achieve high levels of milk production, one should aim at providing a diet that contains all nutrients required by farm animals. Suitable feed for dry cows, or if no long-chop feed for milkers (to reduce risk of acidosis). Unsupplemented dry cow diets seldom provide sodium at >3 g/day. of dry matter straw per day, adjust for moisture content of straw (12 per cent moisture content or 88 per cent dry matter) Evaluating how well the feeding program has worked and implement changes to improve the program, if necessary. This applies to both regular and anionic close-up rations (see Table 3). Ration 2 resulted in a few more open cows than Ration 1, but cow and calf growth were satisfactory. Example: 1,200 lb. For non-pregnant Dry Cows: It is enough to give them maintenance ration of 2 ½ kg. Feed a balanced ration throughout the early and close-up dry period. of dry matter.
