Abstract

Efficiency of different strategies for pig slurry bioacidification to reduce ammonia and greenhouse gas emissions during long term storage

Slurry bioacidification could reduce the need for sulfuric acid and carbon substrates to mitigate gaseous emissions from long-term manure storage.

Abstract

Scoring of swine lung images: a comparison between a computer vision system and human evaluators

The computer vision system could be used as an alternative to the manual scoring of cranioventral pulmonary consolidation during slaughter inspections.

Abstract

Effects of light spectrum on pig behaviour, health and growth

Light spectrum seems to have limited effects on behaviour, health and growth of growing-finishing pigs kept in commercial conditions with limited space and a relatively barren environment.

Abstract

Evaluation of an electrostatic precipitator in mitigating the transmission of airborne viruses in experimentally infected pigs

Under the conditions of this study, the electrostatic precipitators efficiently removed IAV aerosol particles and delayed the onset of IAV and PRRSV infections in the sentinel pigs.

Abstract

Effects of stocking density and illuminance in lairage of fattening pigs in different temperatures

Stocking at too-high density at high temperatures and stocking of too-low density at low temperatures affect meat quality and animal welfare.

Abstract

Genetic parameters for image-based estimations of swine feet and leg conformation traits

The current study presents an algorithm that extracts novel, objective structural conformation traits and reports corresponding genetic and phenotypic parameters.

Abstract

Integrating computer vision algorithms and RFID system for identification and tracking of group-housed animals

The proposed framework enabled reliable tracking of group-housed pigs for extended periods, offering a promising alternative to the independent use of image or RFID approaches alone.

Abstract

Ad libitum feeding systems for lactating sows: effects on productivity and welfare of sows and piglets

Data suggest that sows fed ad libitum eat what they need and can convert feed more efficiently into the piglets’ growth without additional weight loss.

Abstract

Influence of deep-litter bedding materials on environmental and welfare-related factors in boar studs

Trial runs were conducted in winter and summer to compare five deep-litter bedding materials.

Abstract

Enrichment for growing pigs - Impact on behavior and skin lesions

Findings suggest that the choice of point enrichment object can influence the level of interaction, level of interest over time, activity level, and skin lesions in growing pigs.
