Abstract

Subacute ruminal acidosis is a major issue in dairy cattle and a definite diagnosis is only established by measuring the rumen fluid pH, most credibly collected by rumenocentesis. However, due to its invasive nature, there is still some debate whether it is a safe method or poses risks for cows'...

Abstract

Recent studies report considerable variation in ruminal pH for lactating dairy cows even when fed the same diet. We hypothesized that blood metabolites would be indicators of low ruminal pH, and hence could be used as predictors to help manage this variability. The objective of the study was to...

Abstract

Two experiments were carried out to (1) compare pH values of rumen fluid samples (RF) obtained from dairy cows by dorsomedial rumenocentesis, a probe and permanent cannula and (2) to evaluate the effectiveness of the rumenocentesis and its effects on the health and performance of Holstein-Frisian...

Abstract

The objectives of the current study were to evaluate the variation in susceptibility to subacute ruminal acidosis (SARA) among high producing, mid-lactation Holstein dairy cows fed a high-grain diet and to characterize animals that are rumen pH-tolerant to high-concentrate diets. Lactating dairy ...

AbstractFull Text

Objectives: Left displaced abomasum (LDA) is a common postparturient condition of high yielding dairy cattle. The diagnosis of LDA is challenging and has historically been based on findings that are not specific to the condition. The objective of the current study was to investigate the diagnostic...

Abstract

The objective of this study was to evaluate the effects of the rumenocentesis procedure on dairy cows by determining selected metabolic and physiological variables representing the health status. Two groups of 6 cows either underwent rumenocentesis (GA) or sham (GB) procedures. Superficial skin...

Abstract

Rumenocentesis is commonly used to collect rumen fluid to screen for acidosis. This study was designed to investigate whether rumenocentesis induced pain and stress and, if so, whether local anaesthesia could limit this. Twenty-four dairy cows were assigned to one of three treatments: (1) ...

The aim of the study was to characterize the interrelationship between decreased ruminal fluid pH during subacute ruminal acidosis (SARA) and concentrations of principal constituents of milk and biochemical indices associated with nitrogen utilizations such as rumen ammonia nitrogen (RAN), blood...

Abstract

Rumenocentesis is the collection of rumen fluid by percutaneous needle aspiration, under local anaesthetic. It can be done in any ruminant, but is usually reserved for dairy herds, where the monitoring of rumen pH and other rumen health parameters can be particularly valuable. The most easily...

Abstract

The use of rumenocentesis as a tool in veterinary practice was evaluated. This article describes the technique and reports the results of a field study. Rumen fluid samples from 164 dairy cows were collected using rumenocentesis. In order to compare the reaction of the animal to rumenocentesis,...
