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. ...
متن کاملEffects of Rumensin in Lactating Cow Diets with Differing Starch Levels
Kaiser and Shaver (2006) and Bucholtz (2006) reported starch concentrations in diets fed to high-producing dairy herds ranged from 25 to 30 % on a dry matter (DM) basis. Increased corn prices have heightened the interest in feeding reducedstarch diets. Results from short-term dairy cattle feeding trials suggest that reducedstarch diets formulated by partially replacing corn grain with high-fibe...
متن کاملEffect of Rumensin on Health and Reproduction of Lactating Dairy Cows
When Rumensin (monensin sodium) was fed to dairy cows: Services per conception, days open and calving interval were increased, and firstservice conception rate was reduced in the 22 g/ton group. Pregnancy rates and successful calving rates were similar for all treatment groups. All measures of reproductive efficiency for all doses were well within accepted industry standards. The incidence ...
متن کاملAn isotope dilution model for partitioning leucine uptake by the liver of the lactating dairy cow.
An isotope dilution model for partitioning leucine uptake by the liver of the lactating dairy cow is constructed and solved in the steady state. If assumptions ae made, model solution permits calculation of the rate of leucine uptake from portal and hepatic arterial blood supply, leucine export into the hepatic vein, leucine oxidation and transamination, and synthesis and degradation of hepatic...
متن کاملEffect of Rumex Sc on Ruminal Fermentation, Blood Metabolites and Performance of Lactating Dairy Cow
This study investigated the effect of Rumex Sc (commercial product which includes of Saccharomyces cervisiae, saponin and essential oils) on rumen fermentation, blood glucose, urea, milk yield and milk composition. Animals were offered a basal diet containing alfalfa hay (15.5%), corn silage (24%), beet pulp (7%) and concentrate (53.5%). Additionally, Rumex Sc was included in the experimental d...
