PReVeNtING RUMINAL ACIDosIs IN DAIRY CoWs
Feeding dairy cows for maximum milk production increases the risk of ruminal acidosis. Diets fed to high producing dairy cows in North America are typically highly digestible in the rumen and often lack sufficient physical fiber. Rapid fermentation of carbohydrates causes an accumulation of volatile fatty acids (VFA) in the rumen, leading to a drop in ruminal pH. Lack of sufficient physical fib...
متن کاملFeeding a higher forage diet prepartum decreases incidences of subclinical ketosis in transition dairy cows.
A common feeding practice during the dry period is to switch dairy cows to an energy-dense diet 3 wk prepartum, but this practice may lead to the overconsumption of energy and increase the risk of metabolic disease postpartum. The aim of this trial was to compare the metabolic status of transition Holstein dairy cows fed a 77% forage diet (77F; NEl = 1.46 Mcal/kg; NDF = 41%) vs. those fed an 87...
متن کاملSubclinical Hypocalcemia in Dairy Cows: Pathophysiology, Consequences and Monitoring
Milk fever and subclinical hypocalcemia are the most important macro-mineral metabolic disorders that affect transition dairy cows. Many studies have shown that cows with subclinical hypocalcemia are also prone to many diseases and disorders. The drain of Calcium (Ca) during early lactation represents a significant increase in Ca demand over that for late fetal growth and physiological maintena...
متن کاملFurosemide Induced Electrocardiographic Alterations in High Producing Holstein Dairy Cows
Diuretics have several therapeutic advantages in dairy cows but there are different side effects such as acid-base and electrolyte imbalances which may affect the electrocardiographic parameters. Fifteen multiparous, clinically healthy, non-pregnant and high producing 4-year-old Holstein dairy cows at their early lactation period were randomly divided into 3 equal experimental groups. Furosemid...
متن کاملPrevalence of subclinical hypocalcemia in dairy herds.
The prevalence of subclinical hypocalcemia in the transition cow is unknown. Cows with subclinical hypocalcemia have no clinical signs of hypocalcemia but may be more susceptible to other diseases. The objective of this study was to determine the prevalence of subclinical hypocalcemia in the US dairy herds. As a part of the United States Department of Agriculture's National Animal Health Monito...
