Monitoring Metabolic Health of Dairy Cattle in the Transition Period

Relationships between rumination time, metabolic conditions, and health status in dairy cows during the transition period.

The main objective of this experiment was to monitor the rumination pattern during the transition period in primiparous (PR) and pluriparous (PL) dairy cows and to investigate its relationships with metabolic conditions, milk yield, and health status. The study was carried out in an experimental free-stall barn and involved 32 Italian Friesian cows (9 PR and 23 PL) during the transition phase. ...

Animal Health: Dairy Cattle Health – Transition Cows and Mastitis

in lying time among odor treatments. HR piglets exposed to AA, NB or MF had decreased lying time compared with ISO. MR pigs spent more time PFF (interested in the odor) when exposed to MF or NB compared with ISO. LR pigs showed similar PFF when exposed to each odor. HR piglets showed more PFF when exposed to MF than ISO. MR piglets showed more PAF (avoided the odor) when exposed to MP and AA th...

Metabolic Disorders of Dairy Cattle

Dairy cattle metabolic disorders, which are diseases related to disturbance of one or more metabolic processes in the organism are discussed in this overview. The transition period which includes three weeks before and three weeks after parturition is very critical for dairy cows. This period of time is associated with multiple changes including hormonal changes, moving from non-lactating to la...

Direct-fed microbial supplementation on the performance of dairy cattle during the transition period.

The influence of a direct-fed microbial (DFM) on the prepartum period and the effects on production performance during the postpartum period was investigated using 64 multiparous Holstein cows. Two close-up dry cow diets were fed to two groups of 32 cows each starting 21 d precalving as follows: 1) no DFM and 2) DFM. Post-calving cows were fed a lactation ration with or without DFM supplementat...
