The forage cactus plays a fundamental role in animal feed, especially during drought periods in Northeastern Brazil. However, the cultivation and use of this forage require significant labor investment throughout the entire process, from planting to harvesting and daily transport for animal feeding. This study hypothesized that post-harvest storage of the forage cactus cultivars ‘Orelha de Elefante Mexicana’ (Opuntia stricta [Haw.] Haw.) and ‘Miuda’ (Opuntia cochenillifera (L.) Mill), for up to 56 days, may interfere by reducing the digestibility levels and gas production of the forage. The objective was to evaluate the effect of different post-harvest storage times on the in vitro digestibility and in vitro total gas production parameters of the forage cactus cultivars ‘Orelha de Elefante Mexicana’ and ‘Miuda’. The experiment was conducted at the Experimental Farm of the Federal Rural University of Pernambuco (UFRPE) Prof. Antônio de Pádua Maranhão Fernandes, located in Garanhuns - PE, Brazil. The forage cactus used was obtained from a one-year-old cactus plantation established on the farm, preserving the mother cladode during harvest. The experiment was conducted in a completely randomized design, with repeated measures over time and four replicates. Two experiments were carried out, with each cultivar of forage cactus evaluated independently. Eight experimental treatments were evaluated: 0, 8, 16, 24, 32, 40, 48, and 56 days of post-harvest storage. During storage, the aim was to maintain the cladodes without damage throughout the experimental period, with storage taking place in a covered warehouse open on the sides. The samples for analysis were composed of cladodes of different orders and from different parts of the piles. The variables evaluated were in vitro Dry Matter Digestibility (IVDMD), Indigestible Neutral Detergent Fiber (iNDF), and in vitro Total Gas Production (TGP). An analysis of variance was performed, using Tukey’s test with a significance level of 5%. The forage from Orelha de Elefante Mexicana showed high IVDMD, being 823.1 g/kg at time 0 (no storage), and an average of 660.2 g/kg from 8 to 56 days post-harvest. For iNDF, high levels were observed for Orelha de Elefante Mexicana as the storage time increased, with the 40 and 56-day post-harvest times being statistically superior to time 0 (no storage). For Miúda, iNDF on days 32, 40, and 48 of post-harvest storage was 43% higher than at time 0 (no storage). For gas production and fiber carbohydrate degradation, values of 251.5 and 153 mL/g DM were observed, respectively. The forage from Miúda presented high IVDMD at times 0 and 8 (738.4 and 726.4 g/kg), and higher gas production at times 0 and 8 (267.7 and 179.9 mL/g DM, respectively). Both forage cactus cultivars can be stored post-harvest for up to 56 days without significant compromise in digestibility levels and gas production.

This monographic work has as its object of study children's drawings, so it sought to delineate the theme about the use of drawing in art classes, presenting a social and psychological panorama that is attributed to drawing, but linking these to didactic and artistic issues involved in it. The choice for this theme was justified by the constant contact with the children's drawing produced within the preschools, which raised concern about the visible need to revise the purpose of drawing in childhood. In this sense, the general objective was to study “the conception of drawing as an artistic tool in the practice of the preschool teacher”, followed by the specific objectives that guided the research as a whole: to analyze the use of drawing as an artistic tool by Child education; understand drawing as an instrument in child development; observe the practice with the use of drawing in the kindergarten classroom; to this end, a case study was carried out in a kindergarten and elementary school in Santa Cruz do Capibaribe-PE, with a qualitative approach. As a sampling design were focus of the study four preschool teachers with students with an average age between one and a half and four years. In addition to the use of semi-structured questionnaires applied to these teachers. As a theoretical basis, the studies by Ana Mae Barbosa (2008), Zélia Gomes (2009) and Edith Derdyk (1989) were approached in order to support the analysis of the data obtained throughout the research.
