Cow and herd predictors of udder health status in a random sample of argentinian dairy herds
(Universidad de Buenos Aires. Facultad de Ciencias Veterinarias, 2017-11)
The objective of this observational study was to evaluate the relationship between cow- and herd-level factors and cow udder health status, measured by composite milk sample somatic cell count (CSCC) in dairy herds from ...
Estimation of prevalence and incidence of subclinical mastitis in a large population of Brazilian dairy herds
(Elsevier B.V., 2017-08-01)
The objectives of this study were to estimate the prevalence and incidence of subclinical mastitis (SM) in a large population of Brazilian dairy herds and to describe how these indices changed over time. A data set comprising ...
Use of gnrh and pgf(2)alpha for synchronisation of oestrus in confined dairy herds
(UNIV AUSTRAL CHILE, FAC CIENCIAS VETERINARIAS, 1999)
The combination of GNRH and prostaglandin F(2)alpha allows the control of the luteal phase and the follicular dynamic that coexist in the ovary, facilitating precise oestrus synchronisation schemes. The study was intended ...
