In a trial involving 2496 pigs, the effect of transport stocking densities of 201, 241, 281 and 321kg m(-2) on carcass quality and welfare were evaluated. This range encompassed the upper level set for 100kg pigs in European Union legislation (235kg

One of the major stressors associated with the transport of livestock is the thermal microenvironmentin close proximity to the animals. The main determinants of these conditions arethe heat and moisture generated by the animals which needs to be remo

The aerodynamic characteristics of conventional animal transport vehicles have shown that when a vehicle is in motion the solid headboard generates a separated flow region on the front sides of the vehicle (a region of suction). This separated flow e

During production and transportation livestock are frequently exposed to environmental stressors which may compromise both welfare and productivity. Assessment of the degree of physiological stress imposed by these challenges is important. Whilst mea

Whilst improvements have been made over the last 15 years in the collection and transport of live broilers, a satisfactory mechanized system for harvesting birds has yet to be fully accepted by the industry. AFRC Engineering have investigated the mec

This review considers various aspects of electrical stunning of poultry, mainly broilers, with particular reference to electric water bath stunners. Since the welfare of the birds prior to slaughter is of prime importance, areas where this may be com
