Item Desempenho e características de carcaça de cordeiros alimentados com palma forrageira ensilada ou in natura sob restrição ou não de água(2025-03-11) Amaral, Thiago Garcia do; Monnerat, João Paulo Ismério dos Santos; http://lattes.cnpq.br/3851426263880079; http://lattes.cnpq.br/8390297229951855A pecuária no semiárido brasileiro enfrenta desafios devido à escassez hídrica e à baixa disponibilidade de volumosos de qualidade, sendo a palma forrageira uma alternativa para a alimentação e hidratação dos ovinos. No entanto, sua forma de fornecimento pode impactar o desempenho dos animais. Este estudo avaliou os efeitos da palma forrageira in natura e ensilada, associadas ou não à restrição hídrica, sobre o desempenho produtivo e as características de carcaça de cordeiros da raça Santa Inês. Foram utilizados 40 cordeiros machos, não castrados, com idade entre 90 e 120 dias e peso inicial médio de 23,07 ± 2,45 kg, distribuídos em delineamento em blocos casualizados (DBC), num esquema fatorial 2x2, com dois tipos de volumoso (palma in natura + feno ou silagem de palma e feno) e duas formas de oferta hídrica (livre ou restrita). O período experimental foi de 75 dias, incluindo 19 dias de adaptação e 56 dias de coleta de dados. Os tratamentos foram dieta a base de silagem de palma e feno com ou sem restrição de água e outro a base de palma in natura + feno com ou sem restrição de água, ambos na proporção volumoso: concentrado de 65:35. sendo ofertada duas vezes ao dia, às 8h e às 16h. O consumo alimentar foi monitorado diariamente. Ao final do período experimental, os cordeiros foram submetidos a jejum sólido de 16 horas e abatidos. Após o abate, as carcaças foram pesadas feitas avaliações de medidas morfométricas, rendimento de carcaça, deposição de gordura perirrenal e espessura de gordura subcutânea. Os animais que receberam silagem de palma e feno apresentaram maior (P<0,05) desempenho, rendimento dos cortes lombo e serrote e melhor conformação e acabamento, em comparação aos que consumiram palma in natura + feno, entretanto não foi observado efeito (P>0,05) nos rendimentos de carcaça, pH, temperatura, EGS e avaliações morfometricas da carcaça. Por outro lado, a restrição de água não afetou (P>0,05) as características e rendimento de carcaça, engorduramento e as avaliações morfometricas, porém interferiu (P<0,05) negativamente no desempenho, conformação, acabamento e cortes cárneos lombo e serrote dos cordeiros em crescimento, evidenciando a importância do acesso irrestrito à água para o desenvolvimento adequado dos cordeiros. Conclui-se que a utilização da palma forrageira ensilada se mostra como alternativa mais eficiente em comparação à palma in natura, proporcionando maior desempenho produtivo dos animais. A restrição hídrica impacta negativamente o desempenho e as características de carcaça dos cordeiros, independentemente do tipo de volumoso ofertado.Item Visitantes florais da jurubeba (Solanum paniculatum), no Setor de Meliponicultura, do Departamento de Zootecnia da UFRPE (Campus Dois Irmãos)(2025-02-24) Santos, Andreilson José dos; Souza, Darclet Teresinha Malerbo de; http://lattes.cnpq.br/3266223126925865A jurubeba (Solanum paniculatum) é uma planta medicinal indicada para o tratamento de diferentes tipos de doenças. Ela é um arbusto nativo das regiões Norte e Nordeste do Brasil, possui folhas de sabor amargo e frutos amarelo-esverdeados, que também podem ser incluídos na alimentação. O objetivo deste trabalho foi identificar os visitantes florais da jurubeba, tipo de coleta (pólen, néctar e/ou resina) e a frequência dessas visitações. O experimento foi realizado no Setor de Meliponicultura do Departamento de Zootecnia, na Universidade Federal Rural de Pernambuco, em Recife, PE. As observações foram realizadas das 6h às 16h, nos 10 minutos iniciais de cada horário, com três repetições, em três dias distintos, em janeiro de 2024. Foi observada a presença de várias espécies de abelhas, coletando pólen nas flores da jurubeba, entre elas: Augochloropsis sp. (53,7%), Bombus atratus (31,5%) e Melipona scutellaris (3,7%). Outros insetos como dípteros (11,1%) também foram observados nas flores. As abelhas Augochloropsis sp., da família Halictidae, aumentaram sua frequência até 11h, diminuindo após esse horário. As abelhas B. atratus visitaram as flores da jurubeba durante todo o dia, com pico de frequência entre 6h e 7h. As abelhas M. scutellaris visitaram as flores da jurubeba apenas entre 7h e 8h. Os dípteros foram observados apenas entre 9h e 12h. Concluiu-se que a jurubeba é uma planta que fornece pólen para diversas espécies de abelhas, sendo importante para a manutenção da biodiversidade dos polinizadores.Item Análise das condições da comercialização de crustáceos e moluscos nos principais mercados públicos do Recife(2025-02-27) Silva, Lucas Felix da; Porto Neto, Fernando de Figueiredo; http://lattes.cnpq.br/1475750525654086The sale of crustaceans and molluscs in Recife's public markets plays a fundamental role in the local economy, especially considering the city's strategic position as one of the main fishing centers in northeastern Brazil. These products are widely consumed by the population and, in addition to their gastronomic importance, represent a significant source of income for fishermen and traders in the region. However, the sale of these foods in public markets faces specific challenges related to the preservation of quality and food safety, requiring some special attention to handling practices and hygienic conditions. The lack of hygienic standardization, infrastructure and supervision in these markets can cause several problems for consumers. Therefore, this work aims to observe and analyze the conditions of fish marketing, mainly crustaceans and molluscs in the main public markets in Recife.Item Análise de condições de comercialização de peixes nos principais mercados públicos de Recife(2025-02-27) Silva, Gabriella Sá Lucena da; Porto Neto, Fernando de Figueiredo; http://lattes.cnpq.br/1475750525654086In the global context, fish are a crucial source of animal protein for millions of people, with the fishing industry playing a significant role in the economies of various countries, especially in coastal regions. However, global fish production faces challenges such as overfishing, environmental degradation, and the need for sustainable practices. In Brazil, fishing is also a highly relevant activity, with emphasis on the North and Northeast regions, which have vast coastal areas and a rich diversity of marine and freshwater species. The country ranks as one of the largest fish producers in the world, with Brazil being a major exporter of fish products, in addition to meeting the growing domestic demand. However, challenges related to the management of fishery resources, sustainability, and product quality still need to be improved. Recife fits into this context, with a significant fishing economy, both for internal consumption and for the trade of fresh and frozen fish. The Cais de Santa Rita and other local public markets play essential roles in the distribution and sale of these products. However, the city faces structural and operational difficulties regarding the handling and preservation of fish, which directly affects the quality of the products sold and, consequently, public health. This study aims to gather information from the main public markets in Recife and analyze which areas need improvement in the sale of these fish.Item Uso de tampas plásticas como mídia filtrante alternativa em Aquacultura: primeiro protótipo de filtro(2024-10-01) Maranhão, Alberia Jacqueline Alves; Porto Neto, Fernando de Figueiredo; http://lattes.cnpq.br/1475750525654086; http://lattes.cnpq.br/0852093549676817Water use increases as aquaculture grows. The quality and quantity of water is essential for aquaculture, mainly fish farming and indoor shrimp farming (freshwater). Another requirement is the aspect of treated effluents in discharges into the environment. Therefore, the present work aims to test and design a sustainable filter model, using plastic covers as filter media. 10-liter water bottles (PET) were used, perforated on their sides, with around 200 PET bottle caps as filtering media, thus simulating a biological and mechanical filter. Aquarium pumps were introduced inside the bottles, creating a circulation of bubbles where the water is pushed upwards, and water to be filtered enters the bottle in a dynamic water circulation system. Bacteria that settle in the filter will reduce organic matter (nitrogenous nutrients), and the shape of each cap reduces the velocity of particulate matter within the filter, reducing turbidity, and concentrating this particulate organic matter, and other debris, within the filter. filter. This makes filters lighter and cheaper, replacing traditional media (such as those made with ceramic), and reducing the disposal of plastic lids in the environment, reusing this type of material. The experiment was conducted in three 20-liter tanks, supplied with water from fish farming effluents from the Continental Johei Koike Fish Farming Station, at UFFRPE. Physical and chemical data were evaluated every 3 days. The results indicate that there was stabilization of pH, where the water initially had a pH of 6 (on average), to 7. There was an improvement in transparency, and an improvement in the degradation of total ammonia and nitrite, key factors in water quality, aiming to improve the management conditions and productivity in aquaculture.Item Armazenamento pós-colheita da palma forrageira afeta o índice de apodrecimento e a composição química dos cladódios?(2024-09-18) Felix, Thamyres Priscylla Silva de Oliveira; Santos, Mércia Virginia Ferreira dos; Silva, Natália Viana da; http://lattes.cnpq.br/0190091649509674; http://lattes.cnpq.br/9565465836878202; http://lattes.cnpq.br/4093484221298909Item Consumo e digestibilidade de nutrientes em pequenos ruminantes alimentados com dietas contendo gérmen de milho e palma forrageira orelha de elefante mexicana (Opuntia stricta [Haw], Haw])(2024-09-30) Castello Branco, Natália Pereira; Carvalho, Francisco Fernando Ramos de; http://lattes.cnpq.br/8552194153767195; http://lattes.cnpq.br/6243605185116079The aim was to evaluate the effect of using corn germ and forage palm in diets for small ruminants on the consumption and digestibility of nutrients. Four male sheep and four male goats were used, castrated, fistulated and cannulated in the rumen, with an average initial body weight of 38 kg and 35 kg, respectively. The animals were kept in a confinement system in individual stalls (2,0m × 1,0m), with slatted floors and equipped with feeders and drinkers. A Latin square experimental design was used in a 2x4 factorial scheme.The experimental period lasted 88 days, with four experimental periods lasting 22 days each, 14 days for adaptation to the diets and management and 8 days for data and sample collection. The treatments were based on four experimental diets: without forage palm Opuntia stricta [Haw], Haw] (POEM) and corn germ (treatment - CONT); without (POEM) + corn germ (treatment - GIEM); with (POEM) and without corn germ (treatment- POEM); with (POEM) and corn germ (GIEM+POEM). The effects of species (E), treatment (T) and interaction effect of species with treatment (ExT) were evaluated, assuming significance at (P< 0,05). Related to the consumption, no effect of species (E) or interaction between species and treatments (ExT) for none of the variables (P>0,05). A significant effect (P<0,05) of treatments (T) was observed for the consuming variables of dry matter (DM), mineral matter (MM), crude protein (CP), ether extract (EE), total carbohydrates (TCH), non-fibrous carbohydrates (NFC) and total digestible nutrients (TDN). In which the diet containing (GIEM+POEM) promoted greater dry matter intake and other constituents, while the diet (GIEM) promoted lower consumption of dry matter, mineral matter, crude protein, total carbohydrates, non-fibrous carbohydrates and total digestible nutrients, but favored (P<0,05) greater consumption of ether extract along with the diet (GIEM+POEM). The digestibility coefficients of dry matter, crude protein, ether extract and neutral detergent fiber were not influenced by the association of forage cactus with full- fat corn germ (P>0,05), however, significant values were observed (P<0.05) for the organic matter and non-fibrous carbohydrates digestibility coefficients.Item Qualidade de queijos coalhos adicionados de óleos essenciais em sua formulação(2024-09-30) Silva, Maria Manuele Dantas Pereira da; Soares, Luciana Felizardo Pereira; Rocha, Laura Leandro da; http://lattes.cnpq.br/7226123934022759; http://lattes.cnpq.br/4071178363761831; http://lattes.cnpq.br/9024775534481122The objective of this study was to evaluate the physicochemical composition of coalho cheese with the addition of essential oils of oregano, rosemary, and thyme in its formulation at different maturation times. The research was designed as a completely randomized design in a 3x4 factorial arrangement, in triplicate, at three maturation times: 0 (fresh cheese), 15, and 30 days, with four types of coalho cheese: control cheese without essential oil; with oregano essential oil; rosemary oil; and thyme oil, the last three with equivalent concentrations of 40 μL. The physicochemical characteristics of the cheeses at each period were evaluated. The quality of the milk used as raw material was assessed for physical properties, chemical composition, and the presence of pathogenic microorganisms. The milk used as raw material met the quality standards required by legislation. Compared to fresh cheese, a decrease in moisture content was observed over the maturation period, from 55.94% moisture at 0 days to 54.62% and 53.58% at 15 and 30 days, respectively. Regarding the percentage of fat, ash, and acidity, there was a reduction over the evaluated times. There was no significant variation in protein content between the maturation periods. According to the average yields of the treatments (kg), they corresponded to 1.41 kg, 1.30 kg, 1.51 kg, and 1.43 kg for cheeses without oils, with oregano oil, rosemary oil, and thyme oil, respectively. Greater economic viability was observed in cheeses with rosemary and thyme oils, with percentages of 19.5% and 2.9% more favorable compared to the control. The use of essential oils of oregano, rosemary, and thyme in the formulation of coalho cheese proved to be a promising strategy that can modify and improve specific characteristics of coalho cheese, depending on the desired objective. Additionally, it can increase the yield of cheeses with the addition of rosemary and thyme oils, offering a viable and advantageous alternative for the dairy industry and providing differentiated products with higher added value for the consumer market.Item Massa de forragem e valor nutritivo de capim-braquiária [Urochloa decumbens (Stapf) R. D. Webster] sob pastejo em monocultivo, com ou sem adubação, e em sistema silvipastoril(2024-10-01) Cavalcanti, Isaque da Silva; Cunha, Márcio Vieira da; Silva, Rita de Cássia Manso; http://lattes.cnpq.br/0329511011280265; http://lattes.cnpq.br/8936474723708253; http://lattes.cnpq.br/5434373242065945Silvopastoral systems provide significant ecological, economic, and social benefits. These systems can mitigate the negative effects of monoculture on soil by diversifying production through the integration of forestry practices, promoting animal welfare through shading, and enhancing nutrient cycling, which can improve soil fertility, particularly when involving tree legumes. Signal grass (Urochloa decumbens Stapf.) is the most widespread forage species in Brazilian pastures. The hypothesis of this study is that the silvopastoral system with the tree legume sabiá (Mimosa caesalpiniifolia Benth.) improves the nutritional value of Signal grass compared to monoculture, especially without fertilization, without significantly impacting herbage mass. The objective of this thesis was to evaluate herabage mass and the nutritional value of signal grass in monoculture, with or without fertilization (50 kg of N, P, and K ha⁻¹ year⁻¹), and in a silvopastoral system with the sabiá legume, during the rainy season (March to August 2023) and dry season (December 2022 to February 2023 and September to November 2023), in the semi-arid region of Pernambuco, Brazil. The grazing method used was continuous stocking with variable stocking rates, utilizing non-castrated male crossbred Nelore cattle with an average initial live weight of 170 kg. The experimental design was randomized block with three repetitions. The silvopastoral system showed a lower dry mass of green signal grass forage (2045 kg ha⁻¹) compared to the fertilized monoculture (2703 kg ha⁻¹), while it did not differ from the unfertilized monoculture (2327 kg ha⁻¹). Herbage mass was greater during the rainy season (2987 kg ha⁻¹). The silvopastoral system had a lower amount of senescent material compared to the unfertilized monoculture. Additionally, it exhibited a higher incidence of invasive plants compared to monocultures. There were no significant effects of treatments and seasons on the levels of dry matter, mineral matter, organic matter, neutral detergent fiber corrected for ash and protein, and hemicellulose of signal grass (296 g kg⁻¹ DM, 84 g kg⁻¹ DM, 916 g kg⁻¹ DM, 725 g kg⁻¹ DM, and 39 g kg⁻¹ DM, respectively). The crude protein content of the grass in the silvopastoral system was higher (51 g kg⁻¹ DM) than that of the unfertilized monoculture (41 g kg⁻¹ DM) and did not differ from that of the fertilized monoculture (44 g kg⁻¹ DM). However, it was not affected by the time of year. The levels of neutral detergent fiber and acid detergent fiber in signal grass were higher during the rainy season, averaging 794 and 402 g kg⁻¹ DM, respectively. The in vitro digestibility of dry matter of the forage was higher in the dry season (499.8 g kg⁻¹ DM). The silvopastoral system with the sabiá legume, while promoting lower signal grass herbage mass compared to fertilized monoculture, offers nutritional and structural advantages, such as increased crude protein content and reduced dead material, which can enhance animal diet and consumption.Item Benefícios e desafios das feiras agroecológicas de Recife - PE: uma análise da comercialização local(2024-10-01) Silva, Gleyce Kelly de França; Ribeiro, Maria Norma; Rocha, Laura Leandro da; http://lattes.cnpq.br/7226123934022759; http://lattes.cnpq.br/3643578234373660; http://lattes.cnpq.br/8532351925608551
