This experiment investigated the cracked egg ratio and dirty egg ratio in conventional, enrichable, and enriched cages, with 1250 Boris Brawn hens from 24 to 64 weeks of age in an experimental windowless house at Gifu University. At the same time, the influence on the cracked egg ratio and the...

The objectives of the present study were to compare the occurrence of claw lesions, behavior and reproductive performance of pregnant sows housed on either parallel (PRL) or perpendicular slatted floors (PPD). A farrow-to-finish farm was visited three times in 2008 to observe hind claw lesions and ...

The effect of the stall layout on utilization of the feeding place and stall by cows in free-stall housing was investigated. Behaviour of the cows was observed continuously for 24 h on 2 commercial farms with free-stall housing. Two rows of stalls were used in each layout. In Housing-A, the stalls...

There have been requests in recent years to build a all-in-all-out (AIAO) stable pig flow. The purpose of this study was to construct a stable pig flow with AIAO using a judgment tool for multiple pig farms with different breeding styles. The pigflow judgment tool was developed using Microsoft...

Pygmy slow lorises (Nycticebus pygmaeus) are threatened with extinction in the wild. Their nocturnal lifestyle and small size make them difficult to study in their natural habitat, but increasing evidence suggests that they are more social than previously thought.

Wild chimpanzees possess various behavioral skills that allow them to respond flexibly and so adapt to complex environments. However, we lack quantitative data on the number of captive chimpanzees housed in zoos within Japan, with such behavioral skills. In this study, we conducted a survey of...

Many countries have gradually shifted to animal welfare-friendly housing systems for egg layers. However, there is still no consensus among researchers on whether the housing system affects egg quality traits. Therefore, this study aimed to determine the effects of housing systems on egg traits and ...

Stocking density is a crucial factor affecting productivity in aquaculture, and high stocking density is a stressor for aquatic animals. In this study, we aimed to investigate the effects of stocking densities on oxidative stress and energy metabolism in the gills of Cherax quadricarinatus under...

This is the seventh annual report from the Business Benchmark on Farm Animal Welfare.
