Influence Of Neck-Rail Placement On Free-Stall Preference, Use, And Cleanliness, Cassandra B. Tucker, Daniel M. Weary, David Fraser

Three experiments examined how the presence of a neck rail at different heights and locations influenced dairy cattle behavior and stall cleanliness. Experiment 1 compared 4 levels of neck-rail height (102, 114, and 127 cm and no neck rail; presented at 160 or 180 cm from the curb) in a preference test. Cows (n = 10) showed no consistent preference based on neck-rail height, regardless of the horizontal position of the neck rail. When cows were restricted to each treatment in turn, however, time spent standing fully (with all 4 hooves) in the stall was least in the stall with …
Free-Stall Dimensions: Effects On Preference And Stall Usage, Cassandra B. Tucker, Daniel M. Weary, David Fraser
Free-Stall Dimensions: Effects On Preference And Stall Usage, Cassandra B. Tucker, Daniel M. Weary, David Fraser

In 2 experiments, free-stall dimensions were examined to determine how they affected stall preference, usage, cleanliness, and milk production in Holstein dairy cattle. In experiment 1, stall width (112 or 132 cm) and stall length (229 and 274 cm from curb to wall) were compared in a 2 × 2 factorial arrangement of stall treatments using 15 individually housed, non-lactating animals. Cows showed no clear preference for stall size as measured by lying time. When animals had no choice between stalls, average lying time was higher in the wide stalls than in the narrow stalls (10.8 vs. 9.6 ± 0.3 …
Preference Tests Of Ramp Designs For Young Pigs, P. A. Phillips, B. K. Thompson, D. Fraser
Preference Tests Of Ramp Designs For Young Pigs, P. A. Phillips, B. K. Thompson, D. Fraser
Housing and Confinement of Farm Animals Collection
Preference experiments were used to identify features of ramp design that influence the voluntary use of ramps by young pigs. In seven experiments, groups of pigs, aged 7-8 wk, were given free access to four different ramps simultaneously. The animals' behavior was monitored to identify the amount of time spent on the ramps and the number of pigs that failed to use specific designs. Slope, in the range of 20-32° from the horizontal, had a major influence on the pigs' behavior, with the shallower slopes attracting more use than steep ones. Pigs preferred ramps with angle-iron cleats (cross-laid on the …

In discussing animal welfare it is very easy for the discussion to become bogged down by misunderstandings. Commonly the first misunderstanding arises over the definition of animal welfare. In the content of this article we will take it for granted that any definition includes the physical well-being of the animal as well as ensuring that the animal can fulfill much of its genetically controlled behavioral repertoire. The second misunderstanding arises when the political and scientific assessments of the subject are meshed together. In a scientific assessment, the aim should be to examine welfare problems strictly from what we know about …
