Factors Affecting Feed Efficiency of Dairy Cows
Feed efficiency (FE) is a concept that has gained popularity in recent years in the dairy industry. Monitoring FE is becoming a more common benchmark for monitoring the profitability of milk production relative to dry matter (DM) intake. In today’s markets, feeds and commodities are becoming more costly, which is driving the requirement for more efficient utilization to maintain profitability. ...
متن کاملLiver fat content and lipid metabolism in dairy cows during early lactation and during a mid-lactation feed restriction.
During the transition period, the lipid metabolism of dairy cows is markedly affected by energy status. Fatty liver is one of the main health disorders after parturition. The aim of this study was to evaluate the effects of a negative energy balance (NEB) at 2 stages in lactation [NEB at the onset of lactation postpartum (p.p.) and a deliberately induced NEB by feed restriction near 100 d in mi...

متن کاملOvarian function and estrus in dairy cows during early lactation.
The onset of ovarian function and occurrence of estms were monitored in two groups of Holstein cows over the first 90 days postpartum. Group 1 consisted of 36 animals housed in a free stall area and observed continuously for estrus with closed circuit television and a time lapse videorecorder. Group 2 consisted of 33 cows housed in tie stalls with estrus detected by the herdsmen. Blood samples ...
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...
