A comprehensive grazing simulation model, GRASIM, that links components of the pasture system was developed. The grass component of the model contains two main carbon compartments: storage and structure. It accounts for root growth and maintenance, s

Stocking rate is a key management variable in determining productivity and profitability of ganzing systems, but it has not been adequately researched in the USA with high producing dairy cows. A replicated farmlet study was conducted to investigate

A survey of Pennsylvania dairy farmers using (n = 77, PASTURE group) or not using (n = 70, CONFINED group) intensive grazing was conducted in November 1990. The questionnaire was mailed to 147 dairy farmers, of whom 64% responded. Final data analysis

The objectives were to estimate intake of pasture and total DMI by high producing cows grazing grass pastures and to measure changes in nutrient composition of grass pasture during the grazing season. Sixteen multiparous Holstein cows averaging 31 kg

The effects of pasture quality and the amount and nutrient composition of a concentrate supplement on performance of lactating cows were investigated under a controlled rotational grazing system. Pasture samples were collected for two consecutive sum

Cruciferous forages ( Brassica sp. ) contain glucosinolates and S-methylcysteine sulfoxide, compounds that are potentially toxic to livestock, but there is little information concerning the possible effects of ensiling on these constituents. This stu
