Welfare assessment in broiler farms: Transect walks versus individual scoring

The Welfare of Broiler Chickens

Comparative analysis as a management tool for broiler breeder farms: simulated individual farm analysis (IFAS).

The objective of this study was to develop a management information system to evaluate the tactical management of a breeder flock using individual farm analysis with a deterministic simulation model (IFAS). Individual farm analysis is a method that evaluates the performance of individual farms by comparing them with standards. In the first step of IFAS, a farm accounting system is used to compa...

The transect method: a novel approach to on-farm welfare assessment of commercial turkeys

Currently, no animal-based protocol for on-farm welfare assessment of commercial turkeys is available. The birds' size and flighty nature make obtaining a representative sample using traditional methods difficult. The transect walks (TW) approach provides a potential alternative for on-farm assessments of turkey welfare. We compared the TW approach with a traditional method, and data collected ...

Nutritional Management of Broiler Rearing Farms in Guilan, Iran

Tear staining in pigs: a potential tool for welfare assessment on commercial farms.

Tear staining or chromodacryorrhea refers to a dark stain below the inner corner of the eye, caused by porphyrin-pigmented secretion from the Harderian gland. It has been shown to be a consistent indicator of stress in rats and to correlate with social stress and a barren environment in pigs. The current study was, to our knowledge, the first to test it on commercial pig farms as a potential we...
