Effect of freeze-dried pasture herbage on ileal digestibility of amino acids and fatty acids in chickens
lyophilized pasture broilers digestibility fat protein anti-nutritional factors
2018/11/23
The ileal digestibility of amino acids and fatty acids in young chickens fed control diet or experimental diets supplemented with freeze-dried pasture herbage at 20 or 40 g/kg was studied. Control die...
Differences in Voluntary Cow Traffic between Holstein and Illawarra Breeds of Dairy Cattle in a Pasture-based Automatic Milking System
Breed Voluntary Cow Traffic Automatic Milking System
2016/5/16
Automatic milking systems (AMS) rely upon voluntary cow traffic (the voluntary movement of cattle around a farm) for milk harvesting and feed consumption. Previous research on conventional milking sys...
Hungry horses could be more susceptible to contracting Hendra virus, according to the findings of a preliminary study into the effect of pasture availability on infection rates.

Regression analyses showed that the best relationship between solar radiation
and pasture production of an irrigated trial cut on a fortnightly basis over 9
years was P = AR 1 B ~ 2 Cwh ere P was th...
Advection of NH3 over a pasture field and its effect on gradient flux measurements
Advection NH3 pasture field gradient flux measurements
2010/1/20
Deposition of atmospheric ammonia (NH3) to semi-natural ecosystems leads to serious adverse effects, such as acidification and eutrophication. A step in quantifying such effects is the measurement of ...
A daily salt balance model for stream salinity generation processes following partial clearing from forest to pasture
daily salt balance pasture water balance
2009/5/13
We developed a coupled salt and water balance model to represent the stream salinity generation process following land use changes. The conceptual model consists of three main components with five sto...
A conceptual model of daily water balance following partial clearing from forest to pasture
daily water balance streamflow generation processes
2009/5/13
A simple conceptual water balance model representing the streamflow generation processes on a daily time step following land use change is presented. The model consists of five stores: (i) Dry, Wet a...
Dry and wet deposition of inorganic nitrogen compounds to a tropical pasture site（Rondônia, Brazil）
Dry and wet deposition inorganic nitrogen compounds tropical pasture site
2008/12/31
The input of nitrogen (N) to ecosystems has increased dramatically over the past decades. While total (wet + dry) N deposition has been extensively determined in temperate regions, only very few data ...
Nitrous oxide fluxes and nitrogen cycling along a pasture chronosequence in Central Amazonia,Brazil
Nitrous oxide fluxes nitrogen cycling pasture chronosequence Central Amazonia
2010/1/12
We studied nitrous oxide (N2O) fluxes and soil nitrogen (N) cycling following forest conversion to pasture in the central Amazon near Santarém, Pará, Brazil. Two undisturbed forest sites and 27 pastur...
