Herbage production and grazing losses in Panicum maximum cv
Grazing management is a key element determining herbage production and grazing efficiency. This study measured herbage accumulation and grazing efficiency in Mombaça grass pastures (Panicum maximum cv. Mombaça) subjected to intermittent defoliation managements. Treatments were combinations of 2 rest periods (grazing at either 95 or 100% canopy light interception — LI) and 2 grazing intensities ...
متن کاملeffects of stocking density and grazing period on herbage and seed production of paraggio medic
three stocking densities (20, 40, and 60 sheep/ha) were applied in four stocking periods (0, 2, 4, and 6 weeks) on a medicago truncatula cv. paraggio pasture. treatments were arranged in a split plot system and compared through a completely randomised block design with four replications.grazing period had a significant effect (p
متن کاملTechnical Note: Effects of tethering on herbage selection, intake and digestibility, grazing behavior, and energy expenditure by Boer x Spanish goats grazing high-quality herbage.
Twenty-four yearling Boer x Spanish goats were used in a crossover experiment to determine the effects of tethering on herbage selection, intake and digestibility, grazing behavior, and energy expenditure (EE) with high-quality herbage. Four 0.72-ha paddocks of wheat (Triticum aestivum) and berseem clover (Trifolium alexandrium) were grazed in the spring. Each paddock hosted 6 animals, 3 with f...
متن کاملEffects of herbage mass and herbage quality on spatially heterogeneous grazing by cattle in a bahia grass ( Paspalum notatum ) pasture
Small-scale patches (locations of 50 cm × 50 cm at a feeding station level) in a bahia grass ( Paspalum notatum ) pasture under cattle grazing were investigated in terms of herbage mass, quality and utilisation during a grazing season (May–November), to characterise the quantityquality relationship of patches and relate this to spatially heterogeneous grazing by animals. Nitrogen concentration ...
متن کاملCultivar Effects of Perennial Ryegrass on Herbage Intake by Grazing Dairy Cows
Perennial ryegrass is the most abundant grass species in temperate climates. An increased herbage intake of dairy cows by breeding new cultivars could have a large potential impact on agriculture. The effects of cultivars on sward structure, nutritive value, physical characteristics and disease resistance of perennial ryegrass are discussed. Cultivar differences were found in several studies fo...
