    Book synopsis: This book argues that feminist aesthetics as practices of adult education can inform our responses to gendered, racial, class and ecological injustices. It illustrates the critical, creative, and provocative pedagogical theorising, research, and engagement work of feminist adult educators and researchers who work in diverse community, institutional, and social movement contexts across North America and Europe. This book captures the complexity, diversity, energy, and imagination of those who theorise, decolonise, facilitate, investigate, visualize, story, and create within the politics of gender (in)justice and radical change

    Avaliou-se o efeito da suplementação de cromo sobre o desempenho e o rendimento de cortes de frangos, mantidos em ambiente de alta temperatura, no período de um a 42 dias de idade. Foram utilizados 400 frangos de corte, machos, da linhagem Cobb, em um delineamento experimental inteiramente ao acaso, com cinco tratamentos, 0, 350, 700, 1.050 e 1.400ppb de cromo na ração, oito repetições e 10 aves por repetição. Nos períodos de um a 21 e de um a 42 dias de idade, não houve influência dos tratamentos sobre o ganho de peso, o consumo de ração e a conversão alimentar das aves, mas observou-se que o consumo de cromo aumentou de forma linear. Os tratamentos não influenciaram os pesos absoluto e relativo de nenhum dos cortes, peito, coxa e sobrecoxa, avaliados aos 42 dias de idade. A suplementação de até 1.400ppb de cromo na ração não influenciou o desempenho e o rendimento de cortes nobres de frangos de corte mantidos em estresse por calor, no período de um a 42 dias de idade.<br>The effect of dietary organic chromium supplementation on the performance and yield of prime cuts of male broilers from one to 42 days of age reared under high environmental temperature was evaluated. Four-hundred Cobb male broilers, averaging 38±0.14g were distributed in a simple sample random design with five treatments (0; 350; 700; 1,050; and 1,400ppb of chromium in ration), eight replicates, and ten birds per replicates. In periods from one to 21 and from one to 42 days of age, the treatments did not influence the weight gain, the food intake, and the feed:gain ratio of the birds. However, the chromium intake increased in a linear way. No effect of both absolute and relative weights of all evaluated cuts (breast, thigh, and drumstick) was observed. The dietary chromium supplementation up to 1,400ppb did not influence the performance and the carcass traits of the male broilers kept under heat stress from one to 42 days of age
