For 2 grazing seasons, effects of pasture size, stream access, and off-stream water on cow distribution relative to a stream were evaluated in six 12.1-ha cool-season grass pastures. Two pasture sizes (small [4.0 ha] and large [12.1 ha]) with 3 management treatments (unrestricted stream access without off-stream water [U], unrestricted stream access with off-stream water [UW], and stream access...

This paper examines changes in carbon (C) pools associated with land-use, synthesizing data from two experiments dealing with different aspects of tree plantation establishment in Central Panamá. First, we analysed soil profiles in a grazed pasture and an adjacent 5-year-old teak (Tectona grandis) plantation. There were small differences in soil C mass in the top 10 cm of the pasture and the pl...

Methods: The establishment of four native fast-growing tree species in a tropical abandoned pasture was evaluated. Saplings of Cecropia obtusifolia, Hampea nutricia, Omphalea oleifera and Erythrina folkersii were transplanted using a split-plot design. Plant survival and growth were evaluated over 12 mo under two experimental treatments: presence and absence of grasses. Light incidence at groun...

Dairy heifers had an estimated grazed pasture intake of either 11.8 (H) or 6.0 (L) kg DM/heifer/day for four weeks in early lactation and a common pasture allowance thereafter. Group L produced less milk (2202 vs. 2433 R) and milk protein (75.0 vs. 81.6 kg) than Group H in 31 weeks but milk fat yield (104.9 vs. 109.8 kg) and milk composition were not significantly affected. All heifers lost bod...

Tall fescue (Festuca arundinacea) is the most important cultivated pasture grass in the USA, occupying over 35 million acres. It is a native of Europe but is of minor importance there. It is not known when tall fescue was first introduced into the USA but it was being tested in several states by the late 1800s (Buckner et al., 1979). However, tall fescue usage remained low until release of the ...

Milk production of fall-calving dairy cows during subsequent summer grazing was evaluated in two consecutive years using a total of 80 mid- to late-lactation Holsteins. Cows calved during September and October and grazed from April to August in the following year. In yr 1, 27 cows grazed a native grass pasture and 13 cows grazed a native grass-clover mixed pasture containing 26% red clover and ...
