Effects of space allowance on the grazing behaviour and spacing of sheep.
In each of two experiments, four groups of 10 female Scottish Blackface sheep grazed for 2 weeks at each of four space allowances, according to a Greco-Latin Square design. Space allowances were 80, 100, 133 or 200m(2) per head in Experiment 1 and 50, 67, 100 or 200m(2) per head in Experiment 2. Confounding of space allowance and grazing pressure was avoided by the use of a rotational grazing s...
متن کاملGrazing behaviour and diet selection by Dorper sheep.
The grazing behaviour and diet selection by Dorper sheep, as well as other related aspects (pasture intake, walking habits and trampling) is reviewed. It was clear that Dorper sheep are less-selective grazers, compared to Merino-type breeds. Dorpers utilised shrubs and bushes to a greater extent, but grass to a lesser extent in relation to Merino sheep. The Dorper also utilised a larger number ...
متن کاملPen size and parity effects on maternal behaviour of Small-Tail Han sheep.
The aim of this experiment was to study the effects of pen size and parity on maternal behaviour of twin-bearing Small-Tail Han ewes. A total of 24 ewes were allocated to a 2×2 design (six per pen), with parity (primiparous or multiparous) and pen size (large: 6.0×3.0 m; small: 6.0×1.5 m) as main effects at Linyi University, Shandong Province, China. Behaviour was observed from after parturitio...
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 کاملHarris and O'connor: Grazing Behaviour of Sheep on a High-country Range
The distribution of sheep was monitored for three years on part of an unimproved high-country summer range composed of several land units with different phases of degraded tall tussock and short tussock grassland. Sheep distribution was found to be non-random and to vary seasonally. Available dry matter and water content of inter-tussock vegetation were monitored on well vegetated land units fo...
