Impairment of the insulin regulation energy metabolism is considered to be an etiologic key component for metabolic disturbances. Methods studies sensitivity thus are highly topical. There clear indications that reduced contributes disturbances occurs especially among obese lactating cows. Direct measurements laborious and not suitable epidemiological studies. We have therefore adopted indirect method originally developed humans estimate in dairy The method, "Revised Quantitative Insulin...
Most dairy cows experience negative energy balance (NEB) in early lactation because demand for milk synthesis is not met by intake. Excessive NEB may lead to metabolic disorders and impaired fertility. To optimize herd management, it useful detect lactation, but direct calculation of feasible commercial herds. Alternative methods rely on fat-to-protein ratio or concentrations non-esterified fatty acids (NEFA) β-hydroxybutyrate (BHB) blood. Here, we considered assess (EB) based the acid (FA)...
Body condition score and blood profiles have been used to monitor management herd health in dairy cows. The aim of this study was examine BCS extended metabolic profiles, reflecting both energy metabolism liver status around calving high-producing herds with a high incidence abomasal displacement ketosis evaluate if such can be at level pinpoint specific problems.Body five incidences were assessed using linear mixed models (94 cows, 326 examinations). Cows examined sampled every three weeks...
Four lactating Friesian cows with permanent cannulas in the rumen and proximal duodenum were given early (EC)- or late (LC)-cut grass silage ad lib., each either 3 9 kg concentrate dry matter (DM)/d a 4 x Latin square design starting about 10 weeks after calving. Feed was offered twice daily at 08.30 hours 15.30 hours. Periods lasted 5 measurements made last 15 d. The higher amount of concentrates increased total DM intake but reduced fractional rate degradation silage-fibre DM. Later...
This study investigated the fate of glycerol entering rumen, in particular whether could be absorbed across rumen epithelium. Three non-lactating rumen-fistulated cows were used to calculate overall disappearance rate vivo and evaluate ruminal absorption. Rumen epithelial tissues isolated from sheep characterise transport properties. The microbial degradation was then studied an vitro system under anaerobic thermo-regulated conditions. results showed that can significant amounts. fractional...
We have studied the effect of plasma glucose level on abomasal outflow rate fluid using a hyperinsulinemic clamp technique in dairy cows. Four nonpregnant, nonlactating cows were subjected to one following treatments: normoglycemic clamp; hypoglycemic hyperglycemic or, as control, an intravenous infusion .9% sodium chloride Latin square design. The previously fitted with permanent fistula abomasum and was determined Co-EDTA marker assuming that followed first-order kinetics. pH also...
Extending the voluntary waiting period (VWP) for primiparous cows can have a positive impact on fertility without negative milk production per day in calving interval (CInt). We investigated effect of extended VWP during first lactation yield (MY) 2 consecutive lactations cows. The study involved 16 commercial herds southern Sweden. A total 533 Holstein and Red dairy cattle (Swedish Red, Danish Ayrshire) were randomly assigned to conventional 25 95 d (n = 252) or 145 215 281). Data calvings,...
