Impact of an Agroforestry System on Grazing, Ruminating, and Resting Behaviors of Dairy Cows
The present study aimed to evaluate the effects of agroforestry system on the feeding behavior of dairy cows in the Brazilian Amazon region. Nineteen cross breed dairy cows (14.0±3.30 kg/d of milk yield and 450±40.1 kg body weight) were used. The following treatments were evaluated: A) animals were maintained in opened pasture of Brachiaria brizantha during all the day; B) animals were...
متن کاملNitrogen and phosphorus status of soils and trophic state of lakes associated with forage-based beef cattle operations in Florida.
Forage-based livestock systems have been implicated as major contributors to deteriorating water quality, particularly for phosphorus (P) from commercial fertilizers and manures affecting surface and ground water quality. Little information exists regarding possible magnitudes of nutrient losses from pastures that are managed for both grazing and hay production and how these might impact adjace...
متن کاملSoil organic carbon in managed pastures of the southeastern United States of America
Grazing lands in the southeastern United States of America are managed primarily for introduced plant species that have high forage production potential or that fit in a niche within a farming system. Forages are typically managed with fertilization and grazing pressure on a seasonal basis, depending upon growth habit. Nitrogen (N) application is one of the key determinants of pasture productiv...
متن کاملCombination effect of grazing intensity and livestock type (sheep, cattle and integrated grazing) on physical and chemical properties of soil (Case study: woody rangelands of Savadkouh city, Mazandaran)
Intense grazing of rangeland is one of the most important factors affecting rangeland degradation, which causes soil compaction, increased runoff, weakening and degradation of vegetation, and changes in rangeland species composition, and ultimately affects forage and livestock production. The present study was conducted to investigate the different intensities of cattle and sheep grazing and in...
متن کاملForage Intake and Free-ranging Ruminants: a Tropical Perspective
Grasslands in tropical environments are characterized by greater diversity than is found in temperate areas. In South Africa, greater diversity is found with the seasonally limited production which occurs on dystrophic soils under humid conditions in the sourveld, as opposed to the year round production that occurs on eutrophic soils under warm and drier conditions in the sweetveld. Most of the...
