Subclinical ketosis in dairy cattle – the silent profit robber
Successful calving, healthy metabolic functions postpartum and good milk performance in lactation depend highly on the transition period (three weeks before and after calving) of dairy cows where they should be able to manage energy intake and overcome negative energy balance. Subclinical ketosis is one of the metabolic diseases associated with negative energy balance during the transition peri...
متن کاملthe effect of subclinical ketosis in early lactation on productive and reproductive performance of dairy cows in mazandaran province
the objective of this study was to determine cows with subclinical ketosis (sck) with metabolic profile test and subsequent health and productive performances compared to cows without sck. ninety six holstein dry cows were blocked within parity for similar expected calving dates. blood samples were drawn from tail vein 1wk before calving and 1wk after calving. nefa and bhba concentrations were ...

متن کاملScreening for subclinical ketosis in dairy cattle by Fourier transform infrared spectrometry.
Subclinical ketosis is a metabolic disorder in high-producing dairy cattle that can be detected by ketone bodies in milk: acetone (Ac), acetoacetate (AcAc), and beta-hydroxybutyrate (BHBA). Fourier transform infrared (FTIR) spectrometry is to a growing extent used for determination of milk constituents in milk recording, but as yet there is no calibration for ketone bodies available. The object...
متن کاملRelationship between Early Lactation BCS and Mid-Lactation Feed Efficiency in Dairy Cattle
and Implications The relationships between body condition score (BCS) observed during the first 45 days of lactation and two measures of feed efficiency, residual feed intake (RFI) and gross efficiency (GE) defined as milk energy / DMI, measured during mid-lactation were assessed in 255 first lactation Holstein cows. No significant differences in BCS at calving and at approximately 40 days in m...
