This study aimed to evaluate the ability of a saliva collection device (Salivette®) to measure cortisol levels in saliva samples of domestic cats and to assess the effect of a synthetic analogue of the feline facial pheromone fraction F3 (Feliway®) on cortisol levels. A total of 28 domestic cats from a private high-quality sanctuary were sampled before exposure to the facial pheromone and after 35 days of exposure. Two pheromone devices were placed in the area where the animals ate to guarantee the exposure of all cats. The collecting device yielded a sufficient volume of saliva (>0.20mL) to allow cortisol measurement. Cortisol measurements ranged from 0.02g/dL to 0.16μg/dL, with a difference between before (42.1%) and after (62.6%) exposure to the pheromone (F=3.2351; p≤0.0002). No difference in cortisol levels was observed between before (x =0.078μg/dL) and after (x =0.066μg/dL) (t=1.79; p=0.08) exposure. However, salivary cortisol levels decreased in 75% (21/28) of the cats after exposure (x2=12.07; p=0.0005), suggesting that the animals have different susceptibilities to the pheromone or that they spent different lengths of time in the area where the pheromone devices were installed. |

Brazilian Cerrado wheat has emerged as an alternative to expand a new agricultural frontier in tropical areas. In this study, technological quality of 34 samples grown in five locations situated in the Cerrado Mineiro was evaluated in terms of their grain, flour, and starch properties. Damaged starch was positively (p < .05) correlated with Single Kernel Characterization System parameters (r = 0.578) and pasting properties (r = 0.761), and negatively (p < .05) correlated with enthalpy (r = −0.400) and relative crystallinity (r = −0.379). The irrigation system strongly influenced the starch characteristics, rheological, and pasting properties. Piumhi location showed the highest mean of resistant starch (0.80 g/100g), bringing an interesting prebiotic appeal to these samples. Gluten index (mean = 90.6) and damaged starch (mean = 5.0%) values showed that genotypes present suitable standards for bakery products. This pioneering study highlights promising agronomic materials for cultivation in the Brazilian Cerrado region, which has great potential to produce tropical wheat. Practical applications Wheat is the second most significant staple grain after maize, constituting a strategic role in food security to the world economy. In Brazil, more than 90% of wheat is grown in traditional areas that include subtropical climates. In this scenario, Brazilian Cerrado has been standing out as a potential region for wheat cultivation to produce improver wheat class that is the main consumer-driven market. Wheat culture has been adapted under Cerrado conditions after massive investments regarding genetic improvement and integrated soil?water? nutrient? plant practices that allow high grain productivity. Thus, the characterization of wheat grain associated with flour rheological evaluation and starch profile is effective in predicting processing behavior and applicability in different bakery products. The results showed that irrigation system strongly influenced the rheological and pasting properties of starch. These samples showed suitable contents of dry gluten 11%?14%) and damaged starch (4.5%) for bakery products development.
