In one study involving young cattle measurable proxies for pain were identified. Such proxies included heart rate and the plasma concentrations of the stress hormones cortisol, epinephrine, norepinephrine and catecholamine. Heart rate was monitored with standard veterinary ECG equipment and hormone concentrations deter...

c_n82442p8lby6
An increase in any of these stress hormones or vocalization by the animal was assumed to register an increase in pain. A small microphone taped to the calves' throat was used to capture their vocalization response. Twenty-seven calves were divided into three groups.

c_7hkfd7fasjmq
Each group received either a hot-iron brand, a freeze brand using liquid nitrogen, or a "sham" brand. The sham brand was an iron kept at room temperature and pressed to the calves' skin for the same duration as a hot brand. The sham branding created a control group used to determine baseline levels of vocalization and ...

A cannula was inserted into the jugular vein of each calf to sample their blood during branding. These cannula were inserted into each calf 14 to 20 hours before the experiment using squeeze chutes in a different building from the one in which they would be branded.To minimize systematic bias, researchers used blocking...

Heart rates, hormone concentrations, and epinephrine levels, the study's primary pain proxy, were all elevated in hot-branded calves. In terms of vocalization, one hot-branded and two freeze-branded calves expressed distress during branding, although this may have been due to the absence of other cattle in the calf's f...

, and the restriction to monadic logic means that the graph property in question may be defined in terms of sets of vertices of the given graph, but not in terms of sets of edges, or sets of tuples of vertices. As an example, the property of a graph being colorable with three colors (represented by three sets of vertic...
