The transition of pregnancy to lactation, with the concomitant negative energy balance during early requires substantial adaptive performance cow. Apart from clinical disease problems, identification cows suboptimal adaptation is relevant be able adequately treat these animals or modify ration. Effective approaches are necessary provide maximal information at earliest time possible. We therefore aimed identify a measurement that, when applied defined point in relative calving, was as much...
The aim of the present study was to determine effects potential methane reducer fumaric acid on fattening performance and acid-base balance growing bulls fed two different silage types as roughage (maize grass silage). A total 62 (German Holstein breed, initial body weight: 266 +/- 42 kg), randomly assigned eight feeding groups, received four levels (0, 100, 200 or 300 g/d) at each type. daily feed water intake live weight were measured over whole testing period 280 days. In blood samples,...
To investigate the association between haptoglobin concentration in blood and occurrence of ketosis, selected clinical parameters as well lameness dairy cows.The data was collected on 39 farms Bavaria over a period 8 months. In 712 Simmental Brown Swiss cows, examinations milk samplings were performed 10 30 days after calving. these samples, concentrations non-esterified fatty acids (NEFA), β-hydroxybutyric acid (BHBA) (Hp) determined. Analysis included constituents (fat, protein, urea,...
The aim of this observational study was to examine differences in milk fatty acid (FA) concentrations for different metabolic health statuses and associated factors-specifically with which FA an increased risk developing a poor adaptation syndrome (PMAS) associated. During weekly visits over 51 wk, blood samples were collected from cows between 5 50 days milk. farmer corresponding all voluntary milkings. analysis performed on n = 2,432 553 Simmental cows. observations assigned five cow types...
