Evaluation of Brassicas in grazing systems for sheep: I. Quality of forage and animal performance.
Four years of grazing trials were conducted with Brassica forages to evaluate their chemical composition and effect on ADG of fattening lambs and breeding ewes in late fall. Brassicas tested included kales (Brassica oleracea L. var. acephala DC), turnips (B. rapa L.), and a chinese cabbage hybrid (B. rapa L. x B. pekinensis [Lour.] Rupr.). Daily gains of lambs varied widely among years (19 to 3...
متن کاملShort-term foraging dynamics of cattle grazing swards with different canopy structures.
The objective of the present experiment was to describe the sward canopy structures of 3 different wheat (Triticum aestivum L.) pastures and relate them to short-term herbage intake rate and foraging dynamics by steers. Pastures were sampled for leaf and stem fractions at the bottom, middle, and top canopy strata. Sward surface heights and tiller and bulk densities were measured. Herbage was se...
متن کاملComparisons of Cattle Grazing and Sheep Grazing
Controversy has surrounded the possible differences in pasture production which result from grazing by cattle or sheep. Experiments conducted over the 1972-76 period show that pasture production under grazing by sheep is greater than under grazing by cattle under similar intensive managements. A change from sheep grazing to cattle grazing can cause a rapid deterioration in pasture production, w...
متن کاملFORAGE AND GRAZING MANAGEMENT Productivity of Chicory and Plantain Cultivars under Grazing
in 1985 and has been frequently used in the USA where good summer productivity has been reported (Jung et The bimodal distribution of growth of cool-season grass species al., 1996; Volesky, 1996). Chemical analyses indicate generates an imbalance in the amount of forage available during the summer, which could be improved by using alternative forage species. that Puna chicory is a high quality ...
متن کاملInfluence of grazing cattle and sheep together and separately on animal performance and forage quality.
Cattle and sheep grazed together and separately from April to October during 3 yr. Initial forage composition was 29% Kentucky bluegrass (Poa pratensis L.), 11% white clover (Trifolium repens L.), and 60% weeds. There were six Angus cow-calf pairs or six ewes (1/2 Dorset x 1/4 Finn x 1/4 Rambouillet) with 11 lambs per each of three pasture replications for single animal species. Six cow-calf pa...
