Livestock straight-breeding system structures for the sustainable intensification of extensive grazing systems
ICAR Technical Series No 3 Animal breeding aims for genetic improvement of livestock by utilising the genetic variation available, both within breeds and between breeds. The animal genetic variation can be used to accommodate interests and farmers’ wishes to make livestock more efficient in using available resources to produce human food and other agricultural products. In general, improved per...
متن کاملSustainable Rangeland Grazing in Norse Faroe
The introduction of domestic livestock particularly sheep and rangeland grazing by Norse settlers to Faroe during the 9th century has generally been described as a major pressure on a sensitive landscape, leading to rapid and widespread vegetation change and contributing to land degradation. This view has, however, been developed without consideration of Norse grazing management practices which...
متن کاملSupplementary Feeding of Grazing Beef Cattle
Some 60% of Australia% beef cattle are located in the tropics and subtropics, grazing, in general native pastures of low digestibility and N content. Production per head is low, as also are reproductive rates. The nutritional problem centres around the low contents of phosphorus, sulphur and nitrogen in pastures from June to December. This paper discusses responses in breeding cattle to supplem...
متن کاملVariation in absorption and excretion of calcium in grazing sheep in a semi-arid grazing ranch, Punjab, Pakistan
The calcium status of lactating, non-lactating, and male sheep on farm in southwestern Punjab, Pakistan was studied. Pasture and animal were sampled at the end of the first month of summer and winter. All samplings were carried out fortnightly. A mineral supplement was available to all animals throughout the year. Plasma calcium in all animals was not affected by the physiologic state and gende...
متن کاملINVITED REVIEW Sustainable intensification in agricultural systems
†Background Agricultural systems are amended ecosystems with a variety of properties. Modern agroecosystems have tended towards high through-flow systems, with energy supplied by fossil fuels directed out of the system (either deliberately for harvests or accidentally through side effects). In the coming decades, resource constraints over water, soil, biodiversity and land will affect agricultu...
