Sodium bicarbonate as prevention of metabolic acidosis in sheep submitted to experimental ruminal acidosis [PDF]

Pesquisa Veterinária Brasileira, 2014
The aim of this study was to evaluate the preventive effect of sodium bicarbonate on systemic acidosis due to ruminal acidosis, which was induced by ingestion of concentrate after prolonged fasting.

Effects of dietary forage and calf starter diet on ruminal pH and bacteria in Holstein calves during weaning transition

Frontiers in Microbiology, 2016
We investigated the relationship between ruminal pH and bacteria in calves fed calf starter with and without forage during weaning transition. First, 16 Holstein bull calves were obtained from dairy farms and equipped with rumen cannulas by cannulation ...

Starch and oil in the donor cow diet and starch in substrate differently affect the in vitro ruminal biohydrogenation of linoleic and linolenic acids [PDF]

, 2011
Trans isomers of fatty acids exhibit different health properties. Among them, trans-10,cis-12 conjugated linoleic acid has negative effects on milk fat production and can affect human health.

Metatranscriptomic analyses reveal ruminal pH regulates fiber degradation and fermentation by shifting the microbial community and gene expression of carbohydrate-active enzymes

Animal Microbiome, 2021
Background Volatile fatty acids (VFA) generated from ruminal fermentation by microorganisms provide up to 75% of total metabolizable energy in ruminants.

Effects of fat source and dietary sodium bicarbonate plus straw on the conjugated linoleic acid content of milk of dairy cows [PDF]

, 2007
The effects of fat source (0.7 kg of fatty acids from extruded soybeans or palmitic acid), of sodium bicarbonate (0.3 kg) plus straw (1 kg) and the interaction of these treatments on the content of conjugated linoleic acid (CLA) in the milk of dairy cows

Efecto de la altura de pastura sobre el pH ruminal y producción láctea en vacas Holstein, en una pradera de rye grass – ecotipo cajamarquino (Lolium multiflorium) y trébol blanco (Trifolium repens)

Revista de Veterinaria y Zootecnia Amazónica, 2023
Se propuso determinar el efecto de la altura de pastura sobre pH ruminal y producción láctea en vacas Holstein alimentadas en praderas de rye grass y trébol blanco, en Cajamarca. Se determinó altura de la pastura, pH ruminal y producción láctea.

Rumen pH as a Factor for Controlling Feed Intake in Ruminants

Journal of Dairy Science, 1967
Abstract Four rumen fistulated steers, in a 4×4 Latin-square design, received intraruminal infusions of a) water, b) phosphoric acid, c) lactic acid, or d) citric acid, to study the effect of rumen pH on daily hay consumption. Steers were fed chopped hay ad libitum for a 6-hr period daily.

Dietary molasses increases ruminal pH and enhances ruminal biohydrogenation during milk fat depression [PDF]

Journal of Dairy Science, 2011
Feeding high-concentrate diets has the potential to cause milk fat depression, but several studies have suggested that dietary sugar can increase milk fat yield. Two experiments were conducted to evaluate the ability of dietary molasses to prevent milk fat depression in the presence of a 65% concentrate diet. In trial 1, molasses replaced corn grain at

Prediction of Ruminal pH from Pasture-Based Diets

Journal of Dairy Science, 2002
This study identified suitable predictors of ruminal pH and identified relationships between ruminal pH and animal measures for diets based on fresh pasture. Animal and dietary variables (121 treatment means from six countries) were collated from 23 studies of lactating dairy cows fed pasture. Mean daily ruminal pH ranged from 5.6 to 6.7 across studies.

In vitro study of dietary factors affecting the biohydrogenation shift from trans-11 to trans-10 fatty acids in the rumen of dairy cows [PDF]

, 2012
On the basis of the isomer-specific effects of trans fatty acids (FA) on human health, and the detrimental effect of t10,c12-conjugated linoleic acid (CLA) on cows’ milk fat production, there is a need to identify factors that affect the shift from trans-
