Feeding a higher forage diet prepartum decreases incidences of subclinical ketosis in transition dairy cows.
A common feeding practice during the dry period is to switch dairy cows to an energy-dense diet 3 wk prepartum, but this practice may lead to the overconsumption of energy and increase the risk of metabolic disease postpartum. The aim of this trial was to compare the metabolic status of transition Holstein dairy cows fed a 77% forage diet (77F; NEl = 1.46 Mcal/kg; NDF = 41%) vs. those fed an 87...

متن کاملUnderstanding the Impact of Subclinical Ketosis
Dairy cattle experience a remarkable shift in metabolism after calving, after which milk production typically increases so rapidly that feed intake alone cannot meet energy requirements (Bauman and Currie, 1980; Baird, 1982). Cows with a poor adaptive response to negative energy balance may develop hyperketonemia (ketosis) in early lactation. Cows that develop ketosis in early lactation lose mi...
متن کاملEvaluation and use of three cowside tests for detection of subclinical ketosis in early postpartum cows.
The objective was to evaluate the performance of 3 cowside diagnostic tests for detection of subclinical ketosis, defined as a serum beta-hydroxybutyrate (BHBA) concentration >or=1400 micromol/L. On 16 d over a 5-mo period, samples of serum, milk, and urine were collected on a large dairy facility from cows of all parities between 2 and 15 DIM. The sample proportion of subclinical ketosis was 7...
متن کاملEarly embryo development is an indicator of implantation potential.
To maximize the chances of pregnancy during assisted reproduction treatment, it is important to be able to identify embryos with high implantation potential. Embryos which divide more quickly following insemination have been shown to produce higher pregnancy and implantation rates than those which divide later. The aim of this study was to compare the developmental potential of early cleaving e...
