1 Bem-estar e manejo nutricional de fêmeas suínas gestantes: uma breve revisão Well-being and nutritional management of pregnant pigs: a brief review Bienestar y manejo nutricional de hembras porcinas preñadas: una breve revisión Resumo A suinocultura tem recebido um incremento forte, com introdução de novas técnicas e com isso vem crescendo fortemente no Brasil e no mundo. Segundo a Associação Brasileira de Proteína Animal, o Brasil ocupa o 4º lugar como maior produtor e exportador de carne suína. Esses dados mostram que no sistema de produção de suínos o proprietário tem uma extrema importância na área, a qual manejos corretos em todas as fases de criação trazem resultados positivos, assim como perdas na produção no que se diz respeito ao manejo incorreto. Os consumidores estão cada vez mais atentos ao bem-estar animal, estando este quesito entre as exigências principais. O ambiente deve ser limpo e seco e com um manejo correto das canaletas a fim de diminuírem os problemas sanitários. A densidade é de 2,5 m²/animal para fêmeas em baias coletivas e 1,8 m²/animal para leitoas. Recomenda-se atenção redobrada na questão de regular a quantidade de ração fornecida para as fêmeas no final da gestação e lactação. Quanto mais cedo for o diagnóstico de gestação melhor, uma vez que se retira as fêmeas vazias do grupo de parição. O estudo, através de revisão de literatura referente ao bem estar e os manejos para com a gestante suína, auxilia favorecendo procedimentos devidos e alertando acerca dos indevidos para cada situação, de forma a reduzir gastos, assim como, melhorar a questão de bem estar animal.

According to the Brazilian Animal Protein Association, Brazil ranks 4th as the largest pork producer and exporter. These data show that in the swine production system, the owner has an extreme importance in the area, which correct management in all stages of creation bring positive results, as well as losses in production with regard to incorrect handling. Consumers are increasingly aware of animal welfare, with this Research, Society and Development, v. 9, n. 4, e52942829, 2020 (CC BY 4.0) | ISSN 2525-3409 | DOI: http://dx.doi.org/10.33448/rsd-v9i4.2829 3 requirement being among the main requirements. The environment must be clean and dry and with proper handling of the channels in order to reduce sanitary problems. The density is 2.5 m² / animal for females in collective pens and 1.8 m² / animal for gilts. It is recommended that extra attention be given to the question of regulating the amount of feed provided to females at the end of pregnancy and lactation. The sooner the pregnancy diagnosis is better, since the empty females are removed from the farrowing group. The study, through a literature review related to the welfare and management of swine pregnant women, helps by promoting proper procedures and warning about the undue...

The tranquilization of acepromazine and the synergism resulting from its association with xylazine were evaluated. Seven pigs, SRD, healthy, male, aged 60 to 70 days and weighing on average 18.3 ± 2.7 kg were used. Compounds of two groups: group A - acepromazine 1%, 0.1 mg / kg, intramuscular; and 2% AX - xylazine group, 0.3 mg / kg, associated with 1% acepromazine, 0.1 mg / kg, in the same syringe. The following were evaluated: heart rate; systolic blood pressure; respiratory frequency; oxyhemoglobin saturation; body temperature and electrocardiogram. Sedation: absent, discrete or intense sedation. Muscle relaxation: absent, moderate or excellent. Measurement of the parameters: 0 and at 15, 30, 45, 60, 75, 90, 105 and 120 minutes after. The HR was higher in GA. There was no significant difference in f. SpO2 did not vary between groups or between moments. CT significantly reduced GAX. SBP did not vary in both groups. In the ECG, there was a change in the amplitude of the R wave. During the latency period and during the duration of sedation there was no significant difference between groups. In muscle relaxation GAX was higher in M75. Both protocols are safe and promote sedation in pigs, with synergism when using acepromazine associated with xylazine.
