Risk of Milk Fat Depression for Dairy Cows Fed High Moisture Corn and Distillers Grains in Diets Containing Monensin
… exist that when distillers grains are fed milk fat may be depressed. Likewise feeding an ionophore, monensin, will increase efficiency of milk production. Feeding monensin has also been associated with decreased milk fat production. Lastly, feeding large quantities of highly fermentable …

Responses of Rumen Microflora to Whey Products Added to High-Grain Low-Roughage Rations
… to restricted-roughage rations of cows caused milk fat production to return towards normal (5, 26, 27); however, it was not known which component in whey was responsible for correcting milk fat depression. This study was undertaken to determine the population changes of the rumen microflora …

Effects of Replacing Forage Fiber with non-Forage Fiber in Lactating Dairy Cow Diets
… as DDG replaced corn silage in the diet. Milk protein percentage, protein yield, milk lactose percentage and lactose yields were increased. Milk fat percentage, fat yield and feed efficiency were decreased as the percentage of DDG increased in the diets. Milk yield, energy-corrected milk …

The Lipid Composition of Milk as Affected by High Grain-Limited Roughage Rations Containing Whey Products
… a dramatic influence on the lipid composition of milk fat produced. A high grain ration fed with a limited amount of roughage tends to cause a depression in milk fat production while at the same time changing the milk fat composition. There have been various attempts to alleviate the depression in …

Effects of Dietary Conjugated Linoleic Acid Supplementation on Bovine Oocyte Lipid Metabolism, Lipid Composition and Embryo Cryotolerance
… (CLA) was identified as a potent inhibitor of milk fat synthesis in lactating cows (Baumgard et al., 2000) and inclusion of CLA in bovine embryo culture medium improved post-thaw embryo survival (Pereira et al., 2007). Dietary supplementation of cows with CLA could alter oocyte fatty acid …

Identification of molecular targets regulating fatty acid synthesis in bovine mammary epithelial cells
Consumer demand for milk fat has declined due to the increased risk of cardiovascular disease associated with consuming a high saturated fat diet. Milk fat synthesis is energetically expensive for the dairy cow, especially during early lactation or periods of poor nutrition. Thus, manipulating milk …

Intake, growth and rate of digesta passage in ruminating calves fed sodium bicarbonate and disodium phosphate
… of pH, buffering capacity, volatile fatty acids anct ruminal ammonia and blood samples for determination of glucose and plasma urea nitrogen at 8, 11 and 14 wk. Rate of passage was determined using ytterbium and cobalt EDTA to follow the particulate and liquid phases of digesta …

Regulatory factors of milk fat synthesis in dairy cows
… of these studies was to investigate the milk fat synthesis regulation by transcription factors. In the first study, bovine mammary epithelial (MAC-T) cells were treated with sterol regulatory element binding protein-1 (SREBP-1) specific siRNA. The mRNA and protein expression of SREBP-1 …
