Most of the metabolic problems of the dairy cow happen during the first two weeks of lactation. It has been reported nearly 25% of the cows that leave herds do so during the first 60 days in milk (DIM). After calving, the requirements for energy increase due to colostrum production while dry-matter intake is reduced drastically.
With feed as a dairy’s largest expense, between 52 and 58 percent of the total cost of producing milk, feed conversion efficiency has been a valuable benchmark to assess profitability.
Results from a self-administered survey carried out by South Dakota State University dairy researchers among 49 dairy producers showed soybean meal was the protein source most frequently used in their rations (64% of producers),
High feed costs and mounting consumer concerns about the use of antibiotic growth promoters (AGPs) in livestock production provide ample incentive to revisit and refine the use of enzymes in ruminant diets.
The dependence of U.S. dairies on foreign labor is growing significantly. According to a survey published in 2014 by the National Milk Producers Federation, 51.2% of the 150,418 dairy employees were immigrants
A recent study conducted on a commercial dairy in Israel and published in the scientifi c magazine Animal (Shoshani et al., 2016) examined the effects of milking six times daily during the fi rst 21 days of lactation on milk production
The limits established for dairy cattle by the FDA for aflatoxin B1, vomitoxin, and fumonisin are 20 ppb, 5 ppm, and 30 ppm, respectively. The FDA has not published maximum concentrations for other mycotoxins with known deleterious effects on cattle such as T-2 (trichothecenes), ochratoxin, or zearalenone.
Thermostasis is the process by which cows attempt to keep their body temperature constant in spite of changes in environmental temperatures. Heat stress occurs when the cow is incapable of dissipating enough heat to maintain its core body temperature below 101.3°F.
Sorghum is a tropical grass grown primarily in semiarid and dry parts of the world, especially in areas that are too dry for corn. The diverse range of climates that sorghum can grow in, as well as the fact that it is heat and drought tolerant, makes it an important cereal crop. That’s particularly true in dry regions of the world.
The lactational response of dairy cows fed fiber-degrading enzymes has been scarce and inconsistent. The effectiveness of fiber-degrading enzymes to improve milk production has only been observed in 30 percent of studies; however, eight experiments showed positive results.
Corn silage has become one of the most used ingredients in the dairy industry. Its high energy content, coupled with its effective fiber, make corn silage an excellent forage for dairy cows
Forages are, in general, the least expensive source of energy for dairy cows. However, the efficiency of converting forages to milk is limited by the digestibility of forage cell walls
Robotic milking is becoming popular on dairy farms. The University of Minnesota Extension team reported that the top three reasons for installing a milking robot were improved lifestyle
Since feed is the highest individual cost in intensive dairy production systems, the Feeding Technician is one of the most important job positions at the dairy. According to the USDA Economic Research Service (2018), during the last decade feed costs
Soybean meal is the main protein supplement included in U.S. dairy cow diets. However, canola meal has recently become more competitive as a protein source for dairy rations as its availability has improved considerably. Recent expansion of the Canadian canola industry has increased the supply of canola meal.
Feeding for low weigh-backs in high-producing herds
Feed continues to be the highest individual cost in confined dairy production systems. One of the areas of focus for reducing feed costs is the amount of feed weigh-backs (refusals, orts) generated daily on the farm.
Economic impact of fresh cow diseases on farm profitability
Metabolic and hormonal changes that occur during the peri-parturient period of the lactating dairy cow are both profound and significant.
Our mission is clear. We develop and implement strategies for the world’s most ambitious dairy farmers so that they increase their profits and transfer a successful business to the next generation.
Effects of linoleic fatty acid intake on lactating dairy cow performance
Linoleic acid (C18:2) is an unsaturated fatty acid commonly found in dairy ration feed ingredients that may inhibit milk fat synthesis.
