Stocking Density

Effects of holding density on the welfare of zebrafish: A systematic review

The zebrafish is becoming an increasingly popular research animal around the world. Its welfare is affected by an array of environmental factors, such as food access and water quality. Holding density is an important welfare aspect, not least due to...

Housing density and aggression in Syrian hamsters

The Syrian hamster (Mesocricetus auratus) is a solitary and naturally territorial animal, with female hamsters being more aggressive than males. This behavior makes handling difficult because they are usually housed in groups, which can lead to aggressive behavior. The objective...

Plasticity of the skeleton and skeletal deformities in zebrafish (Danio rerio) linked to rearing density

The teleost zebrafish (Danio rerio), an established model for human skeletal diseases, is reared under controlled conditions with defined parameters for temperature and photoperiod. Studies aimed at defining the proper rearing density have been performed with regard to behavioural and...

The influence of stocking density and enrichment on the occurrence of feather pecking and aggressive pecking behavior in laying hen chicks

The housing conditions and environments experienced during the rearing period can influence the development of feather pecking in chickens during this time and in the subsequent laying period. The aim of this study was to investigate the effect of a...

Fish Welfare

Fish have the same stress response and powers of nociception as mammals. Their behavioural responses to a variety of situations suggest a considerable ability for higher level neural processing – a level of consciousness equivalent perhaps to that attributed to...

Evaluation of the effects of space allowance on measures of animal welfare in laboratory mice

We studied how space allowance affects measures of animal welfare in mice by systematically varying group size and cage type across three levels each in both males and females of two strains of mice (C57BL/6ByJ and BALB/cByJ; n = 216...

The effect of space on behaviour in large groups of domestic cats kept indoors

The domestic cat (Felis silvestris catus) originates from the solitary living African wildcat (Felis silvestris lybica). However, through domestication, the domestic cat has become more social towards conspecifics and group housing of cats is common, for example in cat shelters...

Effects of culture densities on feed demand, behavioural tests and on the hepatic and cerebral oxidative status in tilapia (Oreochromis sp

The present study examines whether fish density affects behavioural tests, feed demand, and different parameters indicative of the oxidative status of the liver and brain of Orechromis sp. to identify welfare indicators for fish culturing. The fish were maintained at...

Effect of litter material and stocking density on bone and tendon strength, and productive performance in broilers

Litter material and stocking density were evaluated on welfare-related variables and productive performance in broilers. Male chicks (n = 744, “Ross 308” strain) were raised on either tezontle (TEZ) or wood shavings (WS) litter, with a stocking density of either...

Increasing survival rates in the Zebrafish (Zebra danio) at the University of Manchester

The average survival rate for our Zebrafish (ZF) embryos was 65%. When it was time to create our next generation of Wild Type (WT) (used for embryo production), we decided to run a trial focussing on the effects of feeding...
