PASTURE PRODUCTION is logically measured in terms of grazing animals supported by that pasture. A simple calculation based on stock numbers and area in grassland in New Zealand shows that over the last forty years carrying capacity has increased from 1.4 to 3.2 “sheep units” per acre, or 130% (N.Z. Official Year Book). Obviously many factors have contributed to this increase, including improved...

BACKGROUND Despite an increasing preference of consumers for beef produced from more extensive pasture-based production systems and potential human health benefits from the consumption of such beef, data regarding the health status of animals raised on pasture are limited. The objective of this study was to characterise specific aspects of the bovine peripheral and the gastrointestinal muscosal...

The sugar, starch, and fructan content (collectively referred to as nonstructural carbohydrates [NSC]) of pasture plants is dependent on the environmental conditions under which they have grown. Pasture that is stressed by cold, drought, or lack of nutrients can be 2 to 3 times higher in NSC than pasture that grows quickly in warm weather and is adequately watered and fertilized. Horses at risk...

A significant share of Greenhouse Gases (GHG) produced from agriculture comes from cattle farming. The reduction in GHG emissions from ruminants fed with grains has led some researchers to recommend such a diet as a means of mitigating emissions in the sector. A more accurate balance of emissions, however, must include the carbon (C) stocked by feed crops. Within the grain production system, no...

Many dairy cows in the developed world are now housed exclusively indoors with fewer than 5% of the 10 million lactating cows in the United States having access to pasture during the grazing season. Indoor housing systems are designed to meet biological needs for food, water, hygiene, and shelter, but surveys of public and farmer opinion suggest that people think that pasture access is also imp...

Environment and seedling community under isolated trees in pastures are different from those in the open pasture. The effect of the pasture trees on the soil nutrients and on the seedling growth were investigated. Seven isolated trees and eight plots were selected in two pastures of 12-yr and 32-yr old derived from a lowland rain forest with nutrient-rich soil at Los Tuxtlas, Mexico. The soil c...

Our ability to estimate the changes in carbon (C) pools and fluxes due to forest conversion is hampered by a lack of comparative studies. We measured aboveand belowground C pools and soil respiration flux at four forested and four pasture sites in the southern Appalachian Mountains. Aboveand belowground C pools were significantly larger (P < 0.01, t-test) at forested sites relative to pasture s...

This paper reviews the current use of self-regenerating pasture legumes in the farming systems of southern Europe. Annual legumes are mainly the base for the improvement of low quality native pastures in extensive farming systems. Traditional pasture legumes such as subterranean clovers and annual medics are the base plants of Mediterranean pastures, and are essential for pasture improvement of...

Pasture management can be effective at sequestering soil organic C. We determined the depth distribution of particulate organic C (POC), non-particulate organic C (NPOC), particulate-to-total organic C (POC-to-TOC) ratio, and particulate organic C-to-N (POC-to-N) ratio under pastures near Watkinsville, GA, USA. POC was highly related with total organic C (TOC), but became an increasingly larger...
