This research aimed at assessing the effects of a ceiling fan ventilation system on health, feeding, social behaviour and growth response of finishing young bulls fattened indoors during a mild summer season. A total of 69 Charolais young bulls were housed in six pens without any mechanical ventilation system (Control) and in six pens equipped with ceiling fans. The experimental period lasted 98 days from June until mid-September 2014. Four experimental days were considered in order to assess… Expand
Effects of axial and ceiling fans on environmental conditions, performance and rumination in beef cattle during the early fattening period
Abstract The aim of this study was to assess the effect of two air stirring systems (ceiling fans vs. axial fans) on environment, performance, rumination and activity of beef cattle during the firstExpand
Heat stress effects on Holstein dairy cows' rumination.
TLDR
A statistically significant effect of THI on RT was identified, with RT decreasing as THI increased, and a significant negative correlation was observed between RT and THI. Expand
Dynamic cooling strategy based on individual animal response mitigated heat stress in dairy cows.
TLDR
The sensor-based cooling regime may be an effective tool to detect and ease heat stress in high-producing dairy cows during transitional seasons when heat load can become severe in arid and semi-arid zones. Expand
Risk factors for claw disorders in intensively finished Charolais beef cattle.
TLDR
Benefits for the claw health of finishing Charolaise may come from the use of the deep litter and ventilation systems, the involvement of a nutritionist in diet formulation, and the provision of diets with reduced WSC and increased NDF contents. Expand
Impact of heat stress on milk and meat production
TLDR
The main aspects linked to the effects of heat stress on dairy and beef production are climate change, the simultaneous effect of temperature and humidity factors, and the economic losses due to heat stress. Expand
The impact of smog on the concentration of particulate matter in the antelope house in the Silesian zoological garden
TLDR
Despite fitting existing ventilation system with a filter that reduces the dust level by 60% during the highest level of smog, particulate matter concentration in the antelope house exceeded acceptable limit for PM10 more than twofold. Expand

Fan cooling of the resting area in a free stalls dairy barn
TLDR
The results suggest that using fans in the resting area improves cow comfort, which increases use of the resting areas, and the lying time results also suggest that the benefits of providing ventilation in the rested area might be more evident in barns where there is no paddock. Expand
Feeding behaviour and diet selection of finishing Limousin bulls under intensive rearing system
TLDR
Bull feeding behaviour and its partition was described and bulls performed a selection activity towards the more structured particles of the diet, which may represent an attempt to maintain a sufficient intake of long fibre roughage. Expand
Assessment of welfare of finishing beef cattle kept on different types of floor after short- or long-term housing.
TLDR
Deep litter proved to be a valid alternative to slatted floor, making animals more confident to interact with powerful movements such as mounting at the end of the finishing period, and a negative aspect of the deep litter was the poor cleanliness of the bulls. Expand
Welfare and meat quality of beef cattle housed on two types of floors with the same space allowance
Abstract Growth performance, behaviour, cleanliness, carcass traits and meat quality of 48 Simmental young bulls housed on slatted floor or on straw bedding with the same space allowance wereExpand
Cooling and feeding strategies to reduce heat load of grain-fed beef cattle in intensive housing
TLDR
Six Murray Grey × Hereford yearling steers were used to determine the effect of two cooling treatments (ENV) and two dietary treatments (DIET) – control no added fat or added fat (FAT) – on rectal temperature, respiration rate and dry matter intake (DMI). Expand
Strategies to reduce feedlot cattle heat stress: effects on tympanic temperature.
TLDR
Use of sprinklers can effectively reduce TT of feedlot cattle, whereas shifting to an afternoon vs morning feeding time was most beneficial when bunks were empty several hours prior to feeding. Expand
Effect of summer conditions and shade on behavioural indicators of thermal discomfort in Holstein dairy and Belgian Blue beef cattle on pasture.
TLDR
It is suggested that, even in temperate summers, heat can induce thermal discomfort in cattle, as evidenced by increases in shade use, RR and PS, and that shade increases thermal comfort. Expand
Floor quality and space allowance in intensive beef production: a review
TLDR
Scientific evidence on the effects of floor quality and space allowance on the welfare of finishing beef cattle is reviewed and it is shown that the recommendations made by the Scientific Committee on Animal Health and Animal Welfare are still valid, and are well supported by studies published over the last 10 years. Expand
Shade and water misting effects on behavior, physiology, performance, and carcass traits of heat-stressed feedlot cattle.
TLDR
Cattle without shade had a physiological and behavioral stress response to heat that negatively affected productivity and providing shade for beef cattle was a suitable solution to decrease heat stress and to lower the negative effects of heat on performance, whereas misting was largely ineffective.
