Scientists call pasture a natural eco-system and range is an agricultural eco-system. In this point of view although pasture that was full of plants growing by itself and not growing by human being (Pirdashti, 2007; Mohgadam, 2005) and two groups of living beings such as human being, plants, domesticated, and not living being like weather, Wind, gradient which are effective in making of pasture...

The pasture and animal productivity of established high producing pastures in the Waikato has been compared with newly sown pastures based on recently released herbage cultivars. The established pastures were a mixture of Nui perennial ryegrass, Paspalum dilatatum and Htiia white clover. The new cultivars tested were Ellett perennial ryegrass, Wana cocksfoot and Roa tall fescue, each sown with ...

Organic dairy farmers often introduce alternative pasture species, such as chicory (Cichorium intybus) and narrow-leaved plantain (Plantago lanceolata), to their swards because of their higher mineral contents, yet they are concerned about the presence of weed species such as docks (Rumex spp.) and dandelion (Taraxacum officinale). The mineral content and nutritive value of both desired and les...

The constraints to high levels of milk production imposed by a high-quality-pasture diet, and development of feeding strategies to overcome these limitations, were examined by modelling the nutritional status of New Zealand Friesian and North American Holstein-Friesian dairy cows grazing high-quality pasture. The Cornell Net Carbohydrate and Protein System (CNCPS) was used to predict sensitivit...

THE TERM “pasture quality” is a measure of the ability of the pasture to provide the nutritive requirements of the grazing animal. Many plant constituents contribute to this policy but only one group, the carbohydrates, will be considered here. At present probably the only reliable and meaningful method of assessing the relative nutritive value of different pastures is by comparing actual anima...
