The Effects of Grazing on Botanical Composition in Different Artificial Pastures
Abstract
This research was conducted to determine the effects of grazing on botanical composition
of artificial pastures in Isparta between 2010 and 2012. For this purpose, two different artificial
pastures were established, each covering 1.5 ha area during the first year of the research. The mixtures
of the pastures used were as follows: First pasture: Medicago sativa L. (%20) + Bromus inermis L.
(%40) + Agropyron cristatum L. (%30) + Poterium sanguisorba (%10), second pasture: Medicago
sativa L. (%15) + Onobrychis sativa Lam. (%15) + Agropyron cristatum L. (%35) + Bromus inermis
L. (%35). The grazing applications were conducted in the second and the third years of research.
Twenty Holstein male animals with 6 months old were appointed to experimental area randomly, each
pasture containing 10 calves. Non-grazing areas were established in artificial pastures. Forage samples
were collected from grazing and non-grazing areas once every 15 days during grazing season.
According to results, in the first pasture, alfalfa and crested wheatgrass in grazing areas decreased
at discrete rates while the proportion of burnet and smooth brome grass increased. In the grazing parts
of the second pasture, while alfalfa, sainfoin and crested wheatgrass rate decreased, smooth brome
grass rate increased. In general, burnet was the least preferred species by animals while smooth brome
grass was grazed well during the first period it was not preferred by animals after drying.
