Abstract To determine the effects of maternal nutrition on modifications of foetal development of the skeletal muscle and possible increase in the potential of skeletal muscle growth in cattle, gestating cows were either fed 190% NRC recommendations (overnourished; ON) or 100% NRC recommendation (control; CO). Interaction between maternal nutrition (MN) and the foetal sex (FS) was also investigated. Foetuses were necropsied at four different time points throughout gestation (139, 199, 241 and 268 days of gestation) to assess the mRNA expression of myogenic, adipogenic and fibrogenic markers in skeletal muscle. Phenotypic indicators of the development of skeletal muscle fibres, intramuscular lipogenesis and collagen development were also evaluated. Modifications in mRNA expression of skeletal muscle of foetuses were observed in function of MN and FS despite the lack of effect of MN and FS on foetal weight at necropsy. Maternal ON increased the mRNA expression of the myogenic marker Cadherin-associated protein, beta 1 (CTNNB1) and adipogenic markers Peroxissome proliferator-activated receptor gamma (PPARG) and Zinc finger protein 423 (ZNF423) at midgestation. However, no differences on foetal skeletal muscle development were observed between treatments at late gestation indicating that a compensatory development may have occurred on CO foetuses making the effect of MN on skeletal muscle development not significant at late gestation. Moreover, our data have shown an evidence of sexual dimorphism during foetal stage with a greater skeletal muscle development in male than in female foetuses. In conclusion, providing a higher nutritional level to pregnant cows changes the trajectory of the development of skeletal muscle during midgestation, but apparently does not change the potential of post-natal growth of muscle mass of the offspring, as no differences in skeletal muscle development were observed in late gestation.

Cupania vernalis pertence à família Sapindaceae e é conhecida popularmente como camboatá. Suas sementes apresentam alto teor de umidade e são classificadas como recalcitrantes. Frente à dificuldade de armazenagem e na busca por métodos que acelerem a germinação e emergência, submeteu-se as sementes a diferentes tratamentos de superação de dormência. Foram testados os processos de escarificação, aquecimento em água quente a 50ºC por 5 minutos, desidratação a 40% e testemunha sem tratamento. As sementes tiveram o arilo removido antes da aplicação dos tratamentos. Para cada um dos tratamentos avaliou-se a emergência durante 30, 60 e 90 dias. O aquecimento em água quente a 50ºC por 5 minutos acelerou o processo de germinação, enquanto que o tratamento desidratação apresentou a menor emergência absoluta, ainda que não tenha provocado a total inviabilidade das sementes. Abstract: Cupania vernalis belongs to the family Sapindaceae and it is known than camboatá. Their seeds have high moisture content and are classified as recalcitrant. Facing the difficulty of storing and for methods to speed up germination and emergence, underwent the seeds to different treatments. Scarification, heating in hot water at 50ºc for 5 minutes, dehydration to 40% and control without treatment where tested. The seeds had the aril removed before application the treatments. For each one of the treatments was evaluated at 30, 60 and emergencies during 90 days. Heating in hot water at 50ºc for 5 minutes accelerated the process of germination, while treating dehydration presented the lowest absolute emergency, even though it has not caused the total impracticality of the seeds.
