Abstract: The objective of this work was to evaluate sperm cell motility after intrafollicular artificial insemination (IFAI) in vivo or after incubation in follicular fluid in vitro. In the in vivo experiment, IFAI was performed, followed by the recovery of follicular content 1 to 4 hours later, in order to assess sperm motility. In the in vitro experiment, spermatozoa from a pool of commercial frozen-thawed semen were evaluated for their kinetics after incubation for 1 or 3 hours, either pure (pool, control group) or in follicular fluid (FF). A low motility of sperm cells was observed in the FF samples, both in vitro and in vivo. In vitro, the main parameters negatively affected in the sperm cells incubated in FF, compared with the control, were: total motility (TM), progressive motility (PM), curvilinear distance, and straightness, after 1 hour of incubation; and TM, PM, average path velocity, and curvilinear velocity after 3 hours of incubation. The ovarian follicle and follicular fluid do not provide a suitable environment to maintain bovine sperm cell motility.

ABSTRACT: Gestation length in swine has a considerable amplitude and both early and delayed parturition are common. This variation increases the occurrence of unassisted farrowing and could lead to a wide-ranging age at weaning for piglets born from one batch. Supervision of sow parturition is crucial to reduce mortality of neonate piglets. To facilitate assistance, induction of farrowing using prostaglandin F2α (PGF) has been widely used in batch farrowing systems, whereby synchronization would concentrate the time of farrowing, allowing for better organization of employees. However, a viable alternative method that can be implemented to manage farrowing is to sustain high progestagen levels in the final days of gestation and, consequently, prevent early parturition. Efficient techniques to delay farrowing such as using oral progestagen supplementation have been previously described, but are only recently being considered for commercial use. The present manuscript reviews publications regarding delaying parturition and discusses the use of intravaginal devices (IVDs) containing progestagen. There is limited data addressing the effect of progestagen treatment during gestation on productive and reproductive performance. Therefore, future studies should focus on improving synchronization protocols following progestagen supplementation and evaluating piglet viability and sow fertility, before widely using progestagen supplementation to manipulate parturition.

Na lógica do SUS, as consultas compartilhadas por profissionais de diferentes áreas são utilizadas como uma ferramenta de promoção de saúde, e prevenção de doença, e que também tem por finalidade ampliar o cuidado e dar autonomia para o sujeito com sua própria saúde. As residências Multiprofissionais auxiliam nesse processo, disponde de mais profissionais e qualificando-os para o cuidado integral ao usuário na atenção primária. Com isso o presente artigo trata-se de um relato de experiência sobre consultas compartilhadas realizadas por profissional residente de nutrição e educação física, como também ressaltar a importância do trabalho multiprofissional realizado em uma Unidade Básica de Saúde de um município localizado na região Noroeste do Estado do Rio Grande do Sul. Os profissionais de Educação Física e os Nutricionistas trabalham de maneira semelhante, visando o cuidado sem utilização de tratamentos farmacológicos, assim auxiliam no processo de prevenção de doenças e de promoção de saúde através da proposta de alimentação saudável e prática regular de atividade física. Nessa lógica ampliada do cuidado, profissional da saúde e usuário são responsabilizados, deixando o usuário como protagonista do autocuidado e promoção da própria saúde.
