Cattle Grazing Effect on Mimosa pudica L. in Tropical Pasture System
Mimosa pudica is the most abundant and problematic invasive species in tropical pastures. This study investigates the effects of two cattle grazing systems, long-term moderate grazing (LTG, 2.7 animal unit/ha/yr for 33 years) and short-term heavy grazing (STG, 5 animal unit/ha/yr for 2 years) compared with ungrazed exclosure pasture on the invasion of M. pudica and its relationship with herbage...
متن کاملPrevalence and concentration of Campylobacter in rumen contents and feces in pasture and feedlot-fed cattle.
Campylobacter are important human foodborne pathogens known to colonize the gastrointestinal tract of cattle. The incidence of Campylobacter in cattle may be seasonal and may vary among age groups and type (beef versus dairy). Less is known about other factors that could influence the prevalence, colonization site, and shedding of Campylobacter in cattle. The objectives of this study were to ev...
متن کاملSequential Analysis of Cattle Location: Day-to-Day Movement Patterns*
Bailey, D.W., Walker, J.W. and Rittenhouse, L.R., 1990. Sequential analysis of cattle location: day-to-day movement patterns. Appl. Anita. Behav. Sci., 25: 137-148. Studies were conducted in Texas and Colorado to determine if there were consistent movement patterns of grazing cattle. Based on optimal foraging theory, we hypothesized that cattle would select the same area of a pasture to graze f...
متن کاملNew Concepts in Trace Mineral Supplementation of Grazing Cattle Hydroxy Sources, Injectable Sources and Pasture Application
The trace mineral nutrition of grazing cattle is complicated by several factors among which are the impacts of trace mineral antagonists in grazed forage and the reliance on predictable, uniform intake of free-choice mineral supplements. Numerous options are available to assist in the management of trace mineral nutrition of grazing cattle. In recent years, significant research efforts have bee...
متن کاملCopper supplementation of grazing cattle using pasture topdressing and individual animal treatment
Three methods of copper supplementation were compared in 9to 15-month-old Friesian bulls on a farm with a history of copper deficiency. A group of 60 bulls grazed 19 ha which had been topdressed in May with 120 kg copper sulphate (6.3 kg/ha). Five of the bulls were identified for repeated sample collection. A second group of 60 bulls grazed an untreated area and five of these were each given a ...
