Perfil fermentativo, composição química e estabilidade aeróbia de silagens de brotos de mandioca com palma forrageira

Objetivou-se avaliar o efeito de níveis de palma forrageira (0, 15, 30 e 45%) em silagens de brotos de mandioca sobre o perfil fermentativo, composição química e estabilidade aeróbica. Quatro tratamentos foram testados com 5 repetições, totalizando 20 silos. A inclusão de palma forrageira nas silagens de broto de mandioca promoveu aumento nas perdas por gases (P < 0,001), capacidade tampão (P < 0,001), pH (P = 0,033), matéria mineral (P < 0,001), carboidratos totais (P < 0,001), carboidratos não fibrosos (P < 0,001) e diminuição nos teores de matéria seca (P < 0,001), matéria orgânica (P < 0,001), extrato etéreo (P = 0,002) e proteína bruta (P < 0,001). Efeito quadrático foi observado para perdas por efluentes (P < 0,001), sendo as maiores perdas por efluentes (94.78 kg/t natural matter) obtidas com a inclusão de 30% de palma forrageira nas silagens de brotos de mandioca. A inclusão de palma forrageira na silagem de brotos de mandioca promoveu redução do pH durante a exposição ao oxigênio (P = 0,008). A inclusão de palma forrageira em até 45% na silagem de brotos de mandioca provoca alterações nas características fermentativas e nutricionais, porém, os valores encontrados nas silagens estão de acordo com os padrões de silagens de boa qualidade.The aim was to evaluate the effect of the cactus pear levels (0, 15, 30, and 45%) in cassava shoot silages on the fermentation profile, chemical composition, and aerobic stability. Four treatments were tested with five repetitions, totaling 20 silos. The inclusion of cactus pear in cassava shoots silages promoted an increase in gas losses (P < 0.001), buffering capacity (P < 0.001), pH (P = 0.033), mineral matter (P < 0.001), total carbohydrates (P < 0.001), non-fiber carbohydrates (P < 0.001) and a decreasing in dry matter (P < 0.001), organic matter (P < 0.001), ether extract (P = 0.002), and crude protein (P < 0.001) content. A quadratic effect was observed for effluent losses (P < 0.001), with greater effluent losses (94.78 kg/t natural matter) obtained with the inclusion of 30% cactus pear in cassava shoots silages. Cactus pear inclusion in cassava shoots silage promoted a reduction in the pH during oxygen exposure (P = 0.008). Including cactus pear in up to 45% of cassava silage, shoots cause changes in the fermentation and nutritional characteristics. However, values found in the silages are by good quality standards

Flipchart application for promoting maternal self-efficacy in breastfeeding

Objective: evaluating the effects of using a flipchart as an educational intervention in improving maternal self-efficacy in breastfeeding. Methods: a quasi-experimental study with 41 postpartum women: Intervention Group (n = 20) and Control Group (n = 21) of a public hospital. The intervention consisted of implementing the flipchart “I can breastfeed my baby” in the immediate postpartum and were contacted by telephone after 15 days. For both groups, Breastfeeding Self-Efficacy Scale-Short Form was applied at baseline and after 30 days. Results: before the intervention, the intervention group was 75% with high self-efficacy and 71% of the mothers in the control group of had high self-efficacy. It was found that after educational intervention, all the mothers in the intervention group showed high self-efficacy, while the percentage remained similar to before in the control group (76%). Conclusion: the flipchart had a positive effect on the elevation of self-efficacy in nursing mothers.\u
