Literature review & survey of conditions relevant to farm animal welfare in lairages - MH0132

Description
Lairages have two main roles. First, they provide a point for antemortem inspection and a reservoir of animals so that the slaughter line can run at a constant rate, and therefore efficient speed. Second, they are thought to be beneficial to welfare in allowing animals to rest, and thereby to recover from the stresses of handling and transport from farm or market. This latter role requires that the conditions in the lairage are conducive to rest. They should therefore be as stress-free as possible. There are a number of factors that could contribute to this. Three important ones are that the animals should have enough space, that the ventilation of the lairage should be adequate and that the environment should be reasonably quiet.The purpose of the proposed study is to review the information currently available on stocking densities, ventilation and noise in red meat lairages and the sensitivities and responses of animals to them. Because the amount of information specific to lairages is thought to be very limited, the relevant literature relating to these factors in normal housing systems will be included where it could inform the more specific case of lairages.In order to supplement this review of the literature, a small survey will be carried out in which up to 36 lairages will be visited and measurements made of stocking rates, air quality and ventilation characteristics and noise levels. The outcome of the study will therefore be information on stocking density, noise and ventilation for farmed red meat species that relates to welfare in lairage. It will indicate whether further research is necessary before specific guidelines can be issued for some or all of these factors, or whether current knowledge (including the data from the survey) is sufficient for guidelines to be drawn up following the study. The findings would be disseminated through peer reviewed scientific papers, articles to technical journals, and a guidance leaflet for slaughterplants. Additionally they would be used in established University of Bristol animal welfare training courses.
Objective
Objective 1. Carry out a survey of stocking rates and relate these to the resources available in the pen and the lairage environment.

Objective 2. Carry out a review of literature relating to stocking rates, ventilation and noise in lairages and livestock rearing buildings, and animal responses to these.

Objective 3. Produce a report encapsulating the key findings of (1) informed by (2).
