Seasonality in milk performance and reproduction of dairy cows in low-input farms depending on feeding system
Original language description
The seasonality in milk performance and reproduction was analysed in low-input mountain farms in the Czech Republic. Two different feeding regimes were distinguished: seasonal pasture and all-year-through silage feeding in confinement. Seventeen pasturedherds and sixteen confined herds of Czech Pied and Holstein breeds (in total 12 158 cows) were included in the seven-years observation. The seasonal variation of milk, fat and protein yields per lactation according to the month of calving was found in both the groups of herds. The highest yields were achieved by autumn-calved and the lowest yields by summer-calved cows (difference of 542 kg and 474 kg of milk on average in pastured and in confined herds, respectively). Higher individual daily yields (up to 2.9 kg on average) were recorded in May ? July period than in the rest of a year. No effect of month of calving on days-to-first-service and on days-open period was identified.
