Ammonia (NH3) concentration has seldom been used for environmental control of weaner buildings despite its impact on environment, animal welfare, and workers&rsquo
health. This paper aims to determine the effects of setpoint temperature (ST) on
health. This paper aims to determine the effects of setpoint temperature (ST) on

The activity level of weaned piglets provides a useful tool for farmers to control animal welfare and pollutant emissions. In addition, data for weaned piglet activity can be used as an input signal in real-time ventilation control systems because of

Passive infrared (PIR) detectors are widely used to measure animal activity, which is an increasingly relevant variable for livestock production insofar as activity is an indicator of animal welfare. This paper evaluates the agreement between two ani

Carbon dioxide concentration is a major factor in air quality, animal welfare and air exchange rates inside livestock buildings. CO2 concentration series show a dynamic, non-linear and non-stationary behavior. This type of process can be handled by W

The aim of this study was to determine the effect of stocking density, light intensity and light color on broiler growth. The experiment consisted of four 35-day phases during each of which 320 chickens were surveyed. The research was performed at st

This paper presents an economic study of electricity supply to a dairy cattle farm of 50 livestock units. We compared a stand-alone battery-wind-diesel hybrid system with an only-grid connected system and we analyzed four locations in Spain with diff

A method of estimating the annual average wind speed at a selected site using neural networks is presented. The method proposed uses only a few measurements taken at the selected site in a short time period and data collected at nearby fixed stations
