Description
Experiments were conducted over four consecutive years, with the view to comparing controlled and unrestricted grazing by sheep. Controlled grazing was found to help increasing the green matter yield by 13.3 % and the hay yield by 12.5 %. The actual yield levels resulting from controlled grazing exceeded those obtained after unrestricted grazing by 32.5 % for green matter and by 31.5 % for hay. The utilization coefficient for green matter was higher by 12.5 %- A controlled grazing regime increased the consumption of real forage plants, such as Agrostis vulgaris, Festuca rubra V. Fallax, and Deschamps1a flexuosa, whereas forb consumption declined. The average amount of crude protein in dry matter was 2.04 per cent in excess of that in unrestricted grazing. Controlled grazing can be very effective in conjunction with adequate fertilization, the latter amounting to 320 kg N /ha applied in two portions of 160 kg each in the first and third years, and annual applications of 80 kg N + 80 kg P/ha.
