Ruminal acidosis in beef cattle: the current microbiological and nutritional outlook.
Ruminal acidosis continues to be a common ruminal digestive disorder in beef cattle and can lead to marked reductions in cattle performance. Ruminal acidosis or increased accumulation of organic acids in the rumen reflects imbalance between microbial production, microbial utilization, and ruminal absorption of organic acids. The severity of acidosis, generally related to the amount, frequency, ...
متن کاملSubacute Ruminal Acidosis in Dairy Cattle
Ruminal acidosis is the consequence of feeding high grain diets to ruminant animals, which are adapted to digest and metabolize predominantly forage diets. Feeding diets that are progressively higher in grain tends to increase milk production, even in diets containing up to 75% concentrates. However, short-term gains in milk production are often substantially or completely negated by long term ...
متن کاملRuminal Protein Degradation in Beef Cattle
Five ruminally cannulated steers (initial BW = 375 ± 34 kg; ADG = 1.16 ± 0.13 kg) were used in a 5 x 5 Latin square design experiment to determine the effects of increasing urea level on intake, nutrient digestion, nitrogen balance and ruminal kinetics. Isocaloric (NEm = 2.11 Mcal/kg; NEg = 1.35 Mcal/kg) and isonitrogenous (2.24% N) steam-flaked corn-based diets with urea concentrations of 0.0,...
متن کاملSubacute ruminal acidosis reduces sperm quality in beef bulls.
Breeding bulls are commonly fed high-energy diets, which may induce subacute ruminal acidosis (SARA). In this experiment, 8 Santa Gertrudis bulls (age 20 ± 6 mo) were used to evaluate the extent and duration of effects of SARA on semen quality and the associated changes in circulating hormones and metabolites. The bulls were relocated and fed in yards with unrestricted access to hay and daily i...
متن کاملNew Approaches to Control of Ruminal Acidosis in Dairy Cattle
Eighty Holstein-Friesian cows were randomly assigned to four treatment groups of 20. The four groups of twenty cows were fed on diets that were designed to place cows at some degree of risk of ruminal and metabolic acidosis. The cows were fed either 10 kg of pellet and ate pasture, or a subgroup of six cows per group was fed 10 kg of pellet with ad lib forage in a Calan gate facility. Cows in G...
