“…Prior to each experiment, the chickens were weighed and based on their body weight (BW) divided into experimental groups, so the average weight between treatment groups was as uniform as possible. The ICV injections were done using a microsyringe (Hamilton, Switzerland) without anesthesia in accordance with the technique described by Davis et al (1979) and Furuse et al (1997) in which the head of the birds was held with an acrylic device while the bill holder was at 45° and calvarium parallel to the surface of table (Van Tienhoven and Juhasz 1962). A hole was drilled in a plate laid over the right lateral ventricle.…”

Arva S., Zendehdel M., EbrahimNezhad Y., Ghiasi Ghalehkandi J., Hassanpour S., Aghdam Shahryar H. (2017): Effect of opioid receptors agonists on feeding behaviour using different diets in ad libitum fed neonatal chicken. Czech J. Anim. Sci., 62, 98-109.Despite progress in studying the role of opioids in reward, the effect of opioid receptors on feeding behaviour in ad libitum fed meat-type chicken offered different diet types is still unclear. So in this study, 12 experiments (each included 4 groups) were designed to determine the role of μ, δ, and κ receptors with different diets on feeding responses in ad libitum fed neonatal chicken. In Experiment 1, group A chicken were intracerebroventricularly (ICV) injected with saline, groups B-D chicken were ICV injected with DAMGO (µ-opioid receptor agonist; 125, 250, and 500 pmol), then standard diet without fat was offered. In Experiment 2, group A chicken were ICV injected with saline, groups B-D chicken were ICV injected with DAMGO (125, 250, and 500 pmol) and diet with nutrient energy ratio 20% below standard was provided to the birds. Experiments 3-4 were similar to Experiment 1, except after injection, diets containing nutrient energy ratio 20% above standard and standard diet with fat were provided to the birds, respectively. In Experiment 5, chicken were ICV injected with saline, DPDPE (δ-opioid receptor agonist) at doses of 20, 40, and 80 nmol, and then received standard diet without fat. Experiments 6-8 were similar to Experiment 5 in which diet containing nutrient energy ratio by 20% lower than standard, diet containing nutrient energy ratio by 20% higher than standard, and diet containing fat were provided instead of standard diet without fat to the birds, respectively. In Experiment 9, birds received ICV injection of saline and U-50488H (κ-opioid receptor agonist; 10, 20, and 40 nmol) and were provided standard diet without fat. Experiments 10-12 were similar to Experiment 9 but after ICV injection, birds were fed diet containing by 20% lower nutrient energy ratio, diet containing by 20% higher nutrient energy ratio, and standard diet containing fat, respectively. Then the cumulative food intake was measured until 180 min post injection. According to the results, DAMGO decreased while DPDPE and U-50488H increased the food intake (P < 0.05). These findings suggest endogenous governing food preferences via δ-and κ-opioid receptor in ad libitum fed neonatal chicken.

“…The OU use a head holder [16] to precisely position the injections, whereas freehand injections are used by Monash. Freehand injections are obviously much faster and the injection can be done close to the same time that it takes to train a pair of chicks.…”

“…However, it must be admitted that there is considerable training required before accurate placement of injections can be achieved freehand and with a new or untrained investigator this variability has to be weighed against the time and stress disadvantages of using a head holder. Sandi and Rose [45] point out the use of the modified head holder of Davis et al [16] is itself stressful and note that 'chicks could not be injected earlier than 5 min after training without the injection procedure itself resulting in amnesia'.…”

A comparison of protocols for passive and discriminative avoidance learning tasks in the domestic chick

A one-trial learning task where chicks learn that a bead of a particular shape and/or colour has a bitter taste (100% Methyl anthranilate -MeA) and subsequently avoids it on test has been widely used by research groups across the world. However, there are some differences in the results reported by different research laboratories. One important difference is found when chicks are trained on a diluted bitter taste (10 or 20% MeA) such that memory is not consolidated and fades, e.g. memory lasts for 30 min at Monash and La Trobe Universities versus 4-6 hours at the Open University (OU). Differences in protocol that may explain this apparent discrepancy are whether the chicks have seen the bead before (novelty), and whether the colour or the shape of the bead is a more important feature. In this review, we discuss these and other factors that may contribute to the differences in the characteristics of memory processing between Monash and the OU, e.g. strain, hatchery or laboratory incubated chicks, age at training. It is clear that there is a difference between passive avoidance and discriminative avoidance protocols and this may explain the differences in duration of the memory and the different stages. Is the OU task a more salient experience because of the novelty of the bead and therefore a 'stronger' learning experience? The different protocols may allow different questions to be addressed.
