Intramammary infection rate during the dry period in cows that received blanket dry cow therapy: efficacy of 6 different dry-cow intra-mammary antimicrobial products.

The objectives of this study were to compare the efficacy of 6 different dry-cow intramammary antimicrobial products for the treatment and prevention of mastitis during the dry period in a well-managed high producing Friesland dairy herd, and the influence of treatment on the somatic cell count (SCC) of cows during early lactation. One of 6 dry-cow intramammary antimicrobial products was random...

Potential of fine milk composition for cow udder health management

The objective of this research was to investigate the potential of mid-infrared (MIR) analysis of milk to provide indicators of the udder health status of dairy cows. Mastitis data collected in 49 Walloon herds were merged with test-day data including milk composition and MIR spectra. A total of 1987 healthy lactation and 3204 lactations with at least one mastitis, clinical or sub-clinical, chr...

Optimization of dry period in Karan Fries cow

AIM The objective of this study was to optimize dry period (DP) length that can maximize the production across adjacent lactations and overall lifetime yield. MATERIALS AND METHODS Performance records with respect to DP spread over a period of 15-year in Karan Fries (KF) cattle maintained at Livestock Research Centre (National Dairy Research Institute), were collected for the study. Data of 6...
