Use of Russian plant (Anthemis ruthenica) in feeding sheep during the lactation period.
Because of climate change some xerophytic plants begin to rapidly expand their range becoming invasive species. A typical example is the Russian weed (Anthemis ruthenica). It is eaten by animals since it is distributed in pastures as part of the sheep's feed resources. This is of particular importance for sheep breeding because sheep are often raised in arid regions. This plant is included as hay, especially if drying took place on a hot sunny day, thus this plant is eaten to some extent by sheep. In this study, the introduction of Russian Anthemis ruthenica hay into the diet of dairy sheep led to an increase in milk fat production and significantly affects the liveweight and the physiological state of the sheep. Also, no adverse effects on the performace of sheep were observed.
