We aimed to evaluate the effects of maternal nutrition (MN) and foetal sex on the intestinal development of bovine foetuses throughout different days of gestation (DG). Forty-four multiparous, dry Holstein × Gyr cows with average initial body weight of 480 ± 10 kg were fed the same diet of either restricted feeding at 1.15% of body weight (CO, n = 24) or fed ad libitum (overnourished, ON, n = 20). Six cows from CO group and five cows from ON group were slaughtered at 139, 199, 241 and 268 DG, and foetuses were necropsied to evaluate the intestinal development. The mass, length and density of foetal intestines were not affected by MN (p ≥ 0.260). An interaction between MN and DG was observed for the villi length of jejunum (p = 0.006) and ileum (p < 0.001). Villi length of jejunum and ileum was higher (p < 0.10) in foetuses from ON-fed cows than in foetuses from CO-fed cows at 139 DG. However, at 199 DG, the villi length of jejunum and ileum of foetuses from CO-fed cows was higher than in foetuses from ON-fed cows. Despite these differences, MN did not affect the villi length of jejunum and ileum at 268 DG (p > 0.10). Female foetuses had greater small intestine mass (p = 0.093), large intestine mass (p = 0.022), small intestine mass in proportion to body mass (p = 0.017) and large intestine mass in proportion to body mass (p < 0.001) than male foetuses. Female foetuses had also longer small intestine (p = 0.077) and greater small intestine density (p = 0.021) and villi length of jejunum (p = 0.001) and ileum (p = 0.010) than males. We conclude that MN affects the pathway for the development of foetal villi length throughout the gestation in bovine foetuses without changing the final villi length. Female foetuses had higher intestinal mass, density and villi length than males during the foetal phase in bovines.
A composição de imagens fotográficas de capa da REVISBRATO são os registros que expressam atividades que compõem o Laboratório de Estudos Africanos, integrado às atividades e à Terapia Ocupacional - Iṣẹ́ (Lab-Iṣẹ́) da Universidade Federal do Rio de Janeiro. O Lab-Iṣẹ́ se dedica às atividades através das perspectivas africanas e/ou afro-brasileiras, a fim de restituir a dívida histórica que violou direitos e negligenciou singularidades da população negra. Frente a isso, o Lab-Iṣẹ́ propõe estratégias para enfrentar o racismo e fortalecer as expressões existenciais do povo preto, objetivo central do que este Laboratório tem nomeado de Terapia Ocupacional Afrorreferenciada. Palavras-chave: População negra, Terapia Ocupacional, atividades, Africanas AbstractThe composition of photographs on the cover of the REVISBRATO magazine are the records that express the activities that make up the African Studies Lab, integrated with the activities and Occupational Therapy (OT) - Iṣẹ́ (Lab-Iṣẹ́) of the Federal University of Rio De Janeiro. Lab-Iṣẹ is dedicated to activities through the African and/or Afro-Brazillian perspectives, in order to compensate the historic debt that violated rights and neglected the singularities of the black community. Regarding that, Lab-Iṣẹ́ proposes strategies to face racism and empower the existencial expression of black people. This is the main goal that this Laboratory is calling “Afro-referenced Occupational Therapy”. Keywords: Black community, Occupational Therapy, activities, African Resumen La colección de imágenes de la portada de REVISBRATO son los registros que expresan los trabajos que conforman el laboratorio de Estudios Afrikanos y las actividades de Terapia Ocupacional – Iṣẹ́ (Lab-Iṣẹ́) de la Universidad Federal de Rio de Janeiro. El Lab-Iṣẹ́ desarrolla sus trabajos a través de las perspectivas africanas y / o afrobrasileñas, buscando restaurar la deuda histórica que violó los derechos y desconoció las singularidades de la población negra. En este contexto, el Lab-Iṣẹ́ tiene como objetivo la implementación de lo que han denominado como terapia ocupacional afro-referenciada, proponiendo estrategias para enfrentar el racismo y fortalecer las expresiones existenciales de la población negra.
