Butyrate Metabolism in the Lactating Cow S-

The possibility that butyrate may be glucogenic in ruminants has been suggested by several experimental studies. Intravenous injection of butyrate in sheep was followed by increased concentrations of blood sugar (1) and, in lambs, it was found that butyrate was more effective than propionate for alleviating insulin-induced hypoglycemia (2) ; acetate injection did not have a similar effect in ei...

Wisgraph: Quantifying the Contribution of Non-lactating Cow Udder Infection to the Overall Intramammary New Infection Rate on Wisconsin Dairy

Traditionally, individual cow somatic cell counts (SCC) have been used to identify cows for treatment, segregation, or culling based on counts above a certain threshold – usually defined at around 200,000/ml. This threshold has been used by a number of authors to achieve optimum sensitivity and specificity for the determination of udder infection and non-infection (Dohoo & Leslie, 1991; Scheper...

Conventional and extended intramammary therapy of persistent subclinical mastitis using nafcillin-penicillindihydrostreptomycin in lactating dairy cattle

The objective of the present study was to compare the efficacy of conventional and extendedintramammary (IMM) therapy of persistent subclinical mastitis in lactating dairy cattle using nafcillinpenicillin-dihydrostreptomycin combination (NPD). Sixty-five dairy cows with 126 infected quarters were enrolled in the study. Infected cows were allocated randomly to 1 of 3 different treatment regimens...

Dynamic model of the lactating dairy cow metabolism.

The whole-animal model described in this paper is intended to be a research model with an intermediary structure between sophisticated and simple cow models. The mechanistic model structure integrates the main metabolic pathways of the lactating dairy cow. Milk yield and related feed intake for varying production potentials were considered to be the driving forces and were empirically defined. ...
