Cet article porte sur le mCtabolisme de 1’Cnergie et l’utilisation des substrats dans la sous-alimentation. I1 s’intkresse particulikrement aux Ctudes sur l’homme, bien que des Ctudes sur l’animal soient Cgalement prises en compte, avec des distinctions entre le jeiine aigu (jusqu’h 4 jours), des pCriodes plus longues de sous-alimentation et la dCficience chronique en Cnergie (comme dans la sou...

Observations were collected for the purpose of comparing exit velocity measurements in the form of exit score (ES; walk, trot, canter, or run) and flight speed (FS) as assessments of cattle temperament. Squeeze chute exit velocity was obtained for 1,181 crossbred yearling steers using ES and FS temperament systems. Flight speed used infrared sensors to determine the time taken for an animal to ...

Epidemiological studies can be used to identify risk factors for livestock welfare concerns but have not been conducted in the cow-calf sector for this purpose. The objectives of this study were to investigate the relationships of 1) herd-level management, facilities, and producer perspectives with cattle health and behavior and stockperson handling and 2) stockperson handling on cattle behavio...

The water cushion depth of stilling basin with shallow-water cushion is a key factor that 13 affects the flow regime of hydraulic jump in the basin. However, the specific depth at which the 14 water cushion is considered as “shallow” has not be stated clearly for now, and only conceptual 15 description is provided. This paper attempts to specify the best water cushion depth based on the 16 flow...
