“…Taken together, blue and orange clearly were preferred over green and red, also taken together (F= 10.8, p < .Ol). These preferences are in complete agreement with color preferences of dark-hatched clucks reported in Fischer et al (1975).…”

Four experiments assessed the effects of stimulating chick embryos with colored light at 2 intensity levels. Both posthatch color pecking preferences (Experiments 1 and 2) and color discrimination learning (Experiments 3 and 4) were unaffected. These results affirm and extend a prior finding of no pre- and posthatch colored light stimulation effect on posthatch color preferences in ducklings. The color pecking preferences found replicated prior findings with chicks. However, they differed from the approach color preferences observed in color discrimination learning.

Colour biases are a question of taste

Unpalatable insects often advertise their defences to avian predators by conspicuous colours, such as red and yellow. Therefore, perhaps not surprisingly, birds tend to have unlearned biases against warningly coloured food. These biases are particularly evident when other components of insect warning displays, such as novel sounds and odours, are also present. We tested whether bitter taste, often associated with the defensive chemicals used by aposematic insects, can elicit or enhance specific colour aversions to red and yellow food in young domestic chicks, Gallus gallus domesticus. In our first experiment, subjects were given familiar brown chick crumbs sprayed with either a 0, 1, or 4% quinine solution. In each palatability treatment, chicks were then offered a choice of palatable crumbs that were coloured either red and green or yellow and green. Chicks attacked (pecked or ate) fewer red and yellow crumbs and more green crumbs with increasing quinine concentrations. Chicks also ate fewer red and yellow crumbs with increasing unpalatability, although there was no effect on the numbers of green crumbs eaten. In a second experiment, we gave chicks a colourless drop of either 0 or 0.3% quinine solution and found that this also produced similar attack biases against red and yellow as is in the first experiment. Taken together, these results show that birds use unpalatable taste to adapt their visual foraging decisions, which has consequences for the evolution and stability of mimicry systems, and also has implications for the pairing of colour and taste in psychological experiments.

“…Inherent colour preference was also considered in our experimental design because colour preference in avian species has been previously reported by Ham and Osorio [44]. Broiler breeders showed an inherent colour preference toward the red colour over blue at six weeks of age as previously described Taylor et al [45] and Fischer et al [46].…”

<300) 11 Broiler breeders, the parent stock of meat chicks, are feed-restricted throughout rearing to avoid 12 obesity-related problems in their health and reproductive performance. Broiler breeders often 13 show signs of chronic hunger, lack of satiety and feeding frustration, and the development of 14 alternative feeding strategies has investigated the inclusion of calcium propionate (CaP) as an 15 appetite suppressant. However, the mechanisms involved in the reduction of voluntary feed 16 intake are unknown, but are thought to be due to low palatability, gastrointestinal discomfort, or 17 both. The objective of this experiment was to examine the effect of CaP as an appetite 18 suppressant on the experience of a negative affective state, using a conditioned place preference 19 test. Twenty four broiler breeders were trained to associate the consumption of CaP or a placebo 20 pill with a red or blue place, depending on inherent colour preference. Pullets consumed two pills 21 followed by 20 g feed allotment. The CaP pill contained 160 mg of CaP and the placebo pill had 22 160 mg of feed. Conditioning lasted for 90 min/pullet/day over 8 consecutive days at 7 and 9 23 weeks of age, and pullets' choice was tested in a T-maze twice on two consecutive days at both 8 24 and 10 weeks of age. Data were analysed using a linear mixed regression model, with pen nested 25 in the model and age as a repeated measure. Pullets were less likely to choose the place 26 conditioned with the consumption of CaP (P<0.05) and the preference of the placebo linearly 27 increased with training sessions (P<0.05). These results suggest that calcium propionate as an 28 65The effect of CaP as an appetite suppressant in poultry has been associated with low palatability, 66 gastrointestinal discomfort/malaise or the combination of both [17,23]. Independent of its 67 palatability, whether CaP causes a negative affective state post-ingestion remains unclear. 68The affective states of animals cannot be measured directly, but the study of animals' choices is 69 an indirect approach to assess their preferences [25]. For example, behavioural tests that looked at 70 the affective states and the preferences of broiler breeders include operant learning/response, state 71 dependent learning and conditioned place preference/avoidance [26][27][28][29][30][31]. Conditioned place 72 preference/avoid (CPP/CPA) tests are often used to analyse the possible positive (i.e., rewarding) 73 or negative (i.e., punishing) effects of pharmaceutical drugs or dietary additives [32]. During 74 CPP/CPA tests, animals are trained to associate given characteristics of its environment with 75 affective states induced by the treatment, and this environmental cue can become a conditioned 76 stimulus associated with the given affective state [32,33]. Once the condition is created, animals 77 are hypothesized to prefer the environment associated with the relative higher positive affective 78 state when they are tested in a T-maze [32,33]. Indeed, Phillips and Strojan [34] s...
