“…By using the ANOVA procedure in conjunction with the PROC RANK procedure, data was ranked 'not' by block to analyze the effect of context, whereas traditional method of rank assigning was used, i.e., rank within blocks for the chocolate type. As Friedman's test cannot be used for interaction, another method was used, where the non-normal distributions were transformed by NORMAL = BLOM function of PROC RANK [27]. This function computes normal scores from the ranks using the formula yi = (1/P) (ri-3/8)/(n + 1/4), and after normalization the data were evaluated by using PROC GLM (general linear model) procedure for main and interaction effects.…”

Traditional booths where sensory evaluation usually takes place are highly controlled and therefore have limited ecological validity. Since virtual reality (VR) is substantially interactive and engaging, it has the potential to be applied in sensory science. In this preliminary study, three chocolate types (milk, white, and dark) were evaluated under three contextual settings, including sensory booths (control) and two VR environments (360-degree videos using VR headsets: (i) a pleasant sightseeing tour, and (ii) a live music concert). Untrained participants (n = 67) were asked to rate their liking and the intensity of different chocolate attributes based on the 9-point hedonic scale and just-about-right-scale (JAR). Emotions were evaluated using the check-all-that-apply (CATA) method. Results showed that there were no significant effects of context type on the tasting experience; however, there were significant effects of chocolate type. Milk and white chocolates were preferred over dark chocolate irrespective of the context type. Additionally, more positive emotions were elicited for the dark chocolate in the “virtual live concert” environment. Dark chocolate under the other two environments was associated with negative emotional terms, such as “bored” and “worried.” In terms of more reliable and ecologically valid sensory responses, further research is needed to match suitable VR environments to different chocolate types.

“…It has been investigated that there are many types of behaviors in poultry rearing, such as sitting, lying, standing, feeding, drinking, walking, and preening [44][45][46][47]. Among them, the sitting behavior is a state in which the poultry's ventral part and the fibula and tibia of the leg are in contact with the floor, and it is a behavior that occurs frequently in broilers and laying hens [47][48][49]. This behavior is similar to that observed in our study, and in the case of broilers, it is affected by the rearing density and environment, and the duration time and frequency increase as the body weight increases [50][51][52][53].…”

“…Behavioural changes among animals are observed in response to changes of their physiological parameters, and these changes, can influence their welfare. Thus, behaviour observations are useful to find improvements for animal welfare (Gonçalves et al, 2017).…”

“…Quails housed in higher density environments had longer panting time and greater aggressiveness due the stress. Gonçalves et al (2017) reports that birds gasping is one of the most effective signal of heat loss and, if the relative humidity is appropriate, most birds will be able to dissipate their metabolic heat through this mechanism. Laganá et al (2011) reported that the laying rate increases when birds are submitted to beak trimming due to lower mortality and lower pecking egg index because of less aggressive behaviour.…”

The present experiment was conducted to evaluate the productive performance, egg quality and behavioral patterns of Japanese quails (Coturnix coturnix japonica) with and without beak trimming submitted to two stocking densities. The study was conducted for 84 days. In total, 196 Japanese quails were randomly allocated to a 2 x 2 factorial scheme: submitted or not to beak trimming procedure and low (237.5 cm²/bird) and high stocking density (316.7 cm/bird) and its interaction. Eight replicates per treatment were used, totaling 32 experimental units. Collected data were submitted to analysis of variance and, means of parametric data were compared by Tukey test (p<0.05); otherwise non-parametric analysis of variance were applied for non-parametric data of quail behavior. Lower feed intake was observed in the high stocking density group (p<0.05) but did not affect other parameters (p>0.05). There was no interaction (p>0.05) between beak trimming and stocking density over performance and egg quality. Quails without beak trimming housed in higher density showed more aggressiveness and stress. Egg quality as well as performance parameters of Japanese quails are not affected by applying 316.7 cm2/bird density.
