Simple Summary: This review aims to deepen the understanding of buffalo farming in the Amazon, presenting the quality and nutritional value of buffalo meat and liver. We will explore the characteristics of nutrients and their influence on human health, with a special focus and particular emphasis in vitamins, minerals, and lipids. By investigating fatty acids and cholesterol, we seek to understand the complexity of lipids and their contribution to nutritional quality. The main objective of this study was to provide subsidies to improve buffalo farming practices, promote a healthier human diet and contribute to environmental sustainability in the Amazon region. Thus, this review aims to deepen the understanding of buffalo farming in the Amazon, presenting the quality and nutritional value of buffalo meat and liver. This information serves as a subsidy to improve practices related to the breeding system, nutrition, health and sustainability associated with aquatic buffaloes. For this, a review of the databases was carried out using the descriptors "nutritional value of buffalo meat", "nutritional value of buffalo liver" and "buffalo breeding in the Amazon". Thus, the consumption of foods derived from aquatic buffaloes has important nutritional value for human consumption. In view of this, it is possible to conclude that the nutrition of these animals is influenced by the biodiversity of the Amazon, giving unique characteristics to its products, also highlighting the importance of carrying out research that aims to value the potential use of this species and strengthen the economy of the region.

Simple Summary: The El Niño presents itself as a serious problem in the pastures of the northern region of Brazil, as it compromises the availability and quality of forage and water. Therefore, the objective of this study was to characterize the thermographic profile of three production systems in the Eastern Amazon, Brazil. The results show significant differences between areas with and without chestnut tree shade. Between August and November, the highest temperatures were recorded in full sun pastures, contrasting with lower temperatures in shaded areas. The interaction between the systems revealed significant thermal variations, highlighting the positive impact of native trees on thermal regulation and indicating possible strategies to mitigate the adverse effects of El Niño. The El Niño represents a substantial threat to pastures, affecting the availability of water, forage and compromising the sustainability of grazing areas, especially in the northern region of Brazil. Therefore, the objective of this study was to characterize the thermographic profile of three production systems in the Eastern Amazon, Brazil. The study was conducted on a rural cattle farm in Mojuí dos Campos, Pará, Brazil, between August and November 2023. The experiment involved livestock production systems, including traditional, silvopastoral and integrated, with different conditions of shade and access to the bathing area. An infrared thermographic (IRT) camera was used, recording temperatures in different zones, such as areas with trees, pastures with forage and exposed pastures. The highest mean temperatures (p = 0.02) were observed in pastures with full sun from August to November. On the other hand, the lowest average temperatures were recorded in areas shaded by chestnut trees (Bertholletia excelsa). The highest temperature ranges were found in sunny areas and the lowest were recorded in shaded areas. The highest temperatures were observed in the pasture in full sun, while the lowest were recorded in areas shaded by chestnut trees (p < 0.0001). The interaction between the systems and treatments revealed significant temperature differences (p < 0.0001), with the native trees showing an average temperature of 35.9 °C, lower than the grasses and soil, which reached 61.2 °C. This research concludes that, under El Niño in the Eastern Amazon, areas shaded by Brazil nut trees had lower temperatures, demonstrating the effectiveness of shade. Native trees, compared to grasses and soil, showed the ability to create cooler environments, highlighting the positive influence on different species such as sheep, goats and cattle.

Simple Summary: The objective of this work was to evaluate the effects of climatic conditions and supplementation based on palm kernel cake, on the thermoregulation of crossbred buffaloes in the eastern Amazon. Over a 12-month period, 24 female buffaloes with an initial age of 54 ± 7 months and an average weight of 503.1 ± 23 kg were divided into four groups with different levels of palm kernel cake supplementation relative to body weight. The animals were kept in Brachiaria brizantha pastures with access to water and mineral salt. Supplementation did not influence the physiological variables of thermoregulation. Throughout the year, mean values of rectal temperature, respiratory rate and body surface temperature were higher in the afternoon (p > 0.05). Supplementation with palm cake did not result in influences on the thermoregulation of buffaloes in the study region. The respiratory rate showed an association with the annual seasonality of temperatures, with higher averages in the afternoons of the rainy season. The positive correlation between the rectal temperature, respiratory rate, and body surface temperature indicates that buffaloes respond to atmospheric thermal elevations (afternoon period), which is reflected in increasing thermal indices. In ruminants, diet composition has a positive correlation with heat production, which can influence thermoregulation, energy expenditure and, consequently, animal performance. The objective of this work was to evaluate the effects of climatic conditions and supplementation based on palm kernel cake, on the thermoregulation of crossbred buffaloes in the eastern Amazon. The research was carried out at Embrapa Amazônia Oriental (01°26′ S and 48°24′ W), Belém, Pará, and lasted 12 months (representing the entire year). Twenty-four buffaloes, females, with initial age and an average weight of 54 ± 7 months and 503.1 ± 23 kg, respectively, non-pregnant, non-lactating and clinically healthy were used, divided into four treatments based on the supplementation content of the palm cake (%DM) in relation to their body weight (%): 0, 0.25, 0.50 and 1.0. The animals were kept in paddocks with Brachiaria brizantha (cv. Marandu), in a rotating system, with water to drink and mineral salt ad libitum. Equipment was installed to record environmental data (temperature and relative humidity, dew point temperature, wet bulb and black globe) and physiological data: rectal temperature (RT); respiratory rate (RR); and body surface temperature (BST), recorded twice a day, always in the morning (6:00 a.m. to 7:00 a.m.) and afternoon (12:00 p.m. to 1:00 p.m.) shifts, and were used to calculate the Globe Temperature and Humidity Index (GTHI). Supplementation did not influence the physiological variables of thermoregulation (p > 0.05). However, there were differences in the GTHI between the shifts, with higher means in the afternoon shift, especially in the less rainy period of the year, where the GTHI reached 92.06 ± 2.74 (p < 0.05). In all periods of the year, the mean values of RT, RR and BST were higher in the afternoon shift (p > 0.05). The respiratory rate (RR) is associated with the annual seasonality of the thermal waters, with higher averages in the afternoons of the rainy season. The positive correlation for rectal temperature, respiratory rate and body surface temperature indicated that buffaloes respond to thermal elevations in the atmosphere (afternoon period) and, consequently, reflect on the GTHI. Supplementation does not influence thermoregulation; the changes observed occurred in response to the region's thermal and rainfall conditions (mainly in the afternoon shift), with higher GTHI values.

The objective of this work was to perform the thermographic evaluation of the mammary glands and the eyeball of dairy cattle females on a rural property in the municipality of Mojuí dos Campos, in Western Pará. Eight (n = 8) pluriparous Girolando dairy females were used, maintained in a semi-intensive system, with an average age and weight of 7 years and 450 kg, respectively. The females were divided into two experimental groups, Lactating (LACT, n = 4) and Non-Lactating (N-LACT, n = 4). An infrared thermographic camera was used to obtain the surface temperature of the mammary glands (upper, middle and final third region) and the eyeball. Past version 2.16 was used, obtaining mean and standard deviation and analysis of variance with the Anova One-Waye Tukey test (5%). Mean surface temperature was observed in the mammary glands in the LACT and N-LACT group of 40.2ºC±0.8 and 39.6ºC±0.9, 38.9ºC±0.6 and 38.0ºC±0.7, and 37.5ºC±0.6 and 36.8ºC±0.7 in the upper, middle and final third regions, respectively. The females in the N-LACT group had an average temperature of the eyeball of 36.3ºC ± 0.8 and the LACT 37.3ºC±0.8. There was a numerically higher surface temperature in the mammary gland of lactating females, especially in the upper third, and lower temperatures in the final third (teats), however, statistically significant differences were not detected between the groups (P≥0.05). Greater thermal amplitude was found in the middle third of the mammary glands and higher surface temperature in the eyeball region of lactating females. Thus, infrared thermography is a technique capable of pointing out specific regions in the detection of changes in dairy cattle herds. El objetivo del estudio fue realizar la evaluación termográfica de glándulas mamarias y globo ocular de hembras de ganado lechero en una propiedad rural del municipio de Mojuí dos Campos, en el occidente de Pará.Se utilizaron ocho (n = 8) hembras lecheras multirraciales Girolando, mantenido en un sistema semi-intensivo, con edad y peso promedio de 7 años y 450 kg, respectivamente. Las mujeres se dividieron en dos grupos experimentales, lactantes (LACT, n = 4) y no lactantes (N-LACT, n = 4). Se utilizó una cámara termográfica de infrarrojos para obtener la temperatura superficial de las glándulas mamarias (tercera región superior, media y final) y del globo ocular (región medial). Se utilizó la versión anterior 2.16, obteniendo media y desviación estándar y análisis de varianza con la prueba Anova One-Waye Tukey (5%). Al comparar los grupos LACT y N-LACT, no se detectó diferencia significativa entre ellos (P ≥ 0,05). La temperatura superficial media de las glándulas mamarias en el grupo LACT y N-LACT fue 40,2ºC ± 0,8 y 39,6ºC ± 0,9, 38,9ºC ± 0,6 y 38,0ºC ± 0,7, y 37 , 5ºC ± 0,6 y 36,8ºC ± 0,7 en la tercera región superior, media y final, respectivamente. Las hembras del grupo LACT tuvieron una temperatura media del globo ocular de 37,3ºC ± 0,8 y la N-LACT de 36,3ºC ± 0,8. Se encontró una mayor amplitud térmica en el tercio medio de las glándulas mamarias y una temperatura más alta en la región del globo ocular de las hembras lactantes. Así, la termografía infrarroja pudo determinar que las hembras evaluadas se encontraban en condiciones adecuadas de confort térmico ambiental y los cambios fisiológicos resultantes de la lactancia no lograron provocar un aumento en la temperatura superficial. O objetivo do estudo foi realizar a avaliação termográfica das glândulas mamárias e globo ocular de fêmeas bovinas leiteiras em uma propriedade rural no município de Mojuí dos Campos, no Oeste do Pará. Foram utilizadas oito (n=8) fêmeas leiteiras pluríparas da raça Girolando, mantidas em sistema semi-intensivo, com idade e peso médio de 7 anos e 450 kg, respectivamente. As fêmeas foram divididas em dois grupos experimentais, Lactantes (LACT, n=4) e Não-Lactantes (N-LACT, n=4). Foi utilizada uma câmera termográfica infravermelho para a obtenção da temperatura superficial das glândulas mamárias (região do terço superior, médio e final) e do globo ocular (região medial). Utilizou-se o programa Past versão 2.16, obtendo-se média e desvio padrão e análise de variância com o teste de Anova One-Waye Tukey (5%). Ao comparar os grupos LACT e N-LACT não foi detectada diferença significativa entre os mesmos (P≥0,05). Foram observadas nas glândulas mamárias temperatura média superficial no grupo LACT e N-LACT de 40,2ºC±0,8 e 39,6ºC±0,9, 38,9ºC±0,6 e 38,0ºC±0,7, e 37,5ºC±0,6 e 36,8ºC±0,7 na região do terço superior, médio e final, respectivamente. As fêmeas do grupo LACT apresentaram temperatura média do globo ocular de 37,3ºC±0,8 e as N-LACT de 36,3ºC±0,8. Foi constatada maior amplitude térmica no terço médio das glândulas mamárias e maior temperatura na região do globo ocular das fêmeas lactantes. Assim, a termografia infravermelho foi capaz de determinar que as fêmeas avaliadas estavam em condições adequadas de conforto térmico ambiental e as modificações fisiológicas decorrentes da lactação não foram capazes de ocasionar elevação da temperatura superficial.

The objective of this study was to analyze the perception of risk in the use of agrochemicals regarding the use and disposal of empty packaging in vegetable gardens in the municipality of Santarém, Pará. The study was carried out in the municipality of Santarém, Pará, in order to verify the perception of producers who use agrochemicals in vegetable gardens, thus, were evaluated on the spot with the application of a questionnaire containing 10 open and closed questions, with 7 vegetable producing communities being evaluated (Área Verde, Cristo Rei, Floresta, Jutaí, Mararu, Tabocal and Urumanduba ), totaling 30 farmers. Analyzing the results, it was observed that all producers respect the grace period and a large part makes use of conventional methods, following mainly as label instructions, it was also observed that most producers receive guidance from professionals with technical knowledge on the subject. It was noticed that the most widely used agrochemical was the insecticide, besides, only a small part of the producers used complete personal protective equipment and most of them wash the after use, however, they do not perform a triple washing of the empty packaging. Finally, it can be seen that most producers are unaware of the collection point and discard the packaging of agrochemicals mainly in the trash. In view of the above, it is concluded that vegetable producers in the municipality of Santarém do not correctly dispose of empty agrochemical packages, discarding them in an advanced environment, and no producer returned a package at the collection point as recommended by Brazilian legislation. O objetivo neste estudo foi analisar a percepção de risco no uso de agroquímicos quanto a utilização e descarte das embalagens vazias em hortas no município de Santarém, Pará. O estudo foi realizado no município de Santarém, Pará, com o intuito de verificar a percepção dos produtores que utilizam agroquímicos em hortas, assim, foram realizadas entrevistas in loco com aplicação de questionário contendo 10 perguntas de caráter aberto e fechado, sendo avaliadas 7 comunidades produtoras de hortaliças (Área Verde, Cristo Rei, Floresta, Jutaí, Mararu, Tabocal e Urumanduba), totalizando 30 agricultores. Analisando os resultados, observou-se que todos os produtores respeitam o período de carência e grande parte faz uso de métodos convencionais, seguindo principalmente as instruções do rótulo, observou-se também que a maioria dos produtores recebe orientação de profissionais com conhecimento técnico sobre o assunto. Percebeu-se que o agroquímico mais adotado foi o inseticida, além disso, apenas uma pequena parte dos produtores utiliza equipamento de proteção individual completo e a maioria realiza a lavagem das roupas após a utilização, entretanto, não realizam a tríplice lavagem das embalagens vazias. Por fim, pode-se perceber que grande parte dos produtores não tem conhecimento sobre o posto de coleta e descartam a embalagem dos agroquímicos principalmente no lixo. Diante do exposto, conclui-se que os produtores de hortaliças do município de Santarém não fazem o descarte correto das embalagens vazias de agroquímicos, descartando-as em ambiente inadequado, sendo que nenhum produtor devolveu a embalagem no posto de coleto conforme preconiza a legislação brasileira.

The aim of this study was to present a systematic review and scientometric analysis on commercial eggs production in Brazil. For the systematic review, articles targeted to the described subtopics were selected. In contrast, the scientometric analysis was performed considering the articles indexed on CAPES, SCIELO, SCORPUS and WEB OF SCIENCE platforms. Subsequently, the articles found were analyzed and grouped according to the number of publications per year, the theme addressed in the publications, regions where the publications occurred, main authors, list of journals where the articles were published and the qualifications of the journals. The results showed that articles on commercial eggs have decreased in recent years, with Salmonella detection and contamination being the most addressed topic (30%). In addition, it was possible to observe that publications are more concentrated in the Southeast (35%) and Northeast (15%). The author with the most publications on the subject was Pinto, A. T., being the journal Arquivo Brasileiro de Medicina Veterinária and Zootecnia being the one that published the most on the subject (20%). Finally, all articles found were published in a journal with expressive qualities greater than B3, with A2 being the one that most covered the publications, totaling 40%, demonstrating the importance of the theme. Furthermore, it is concluded that there are regions where research on commercial eggs production is still not widespread. In addition, this study presents a current overview of the production of commercial eggs in Brazil, providing possibilities for expanding knowledge through studies in areas and topics little researched. El objetivo de este estudio fue presentar una revisión sistemática y análisis cienciométrico sobre la producción comercial de huevos en Brasil. Para la revisión sistemática se seleccionaron artículos dirigidos a los subtemas descritos. Por el contrario, el análisis cienciométrico se realizó considerando los artículos indexados en las plataformas CAPES, SCIELO, SCORPUS y WEB OF SCIENCE. Posteriormente, los artículos encontrados fueron analizados y agrupados según el número de publicaciones por año, el tema abordado en las publicaciones, las regiones donde ocurrieron las publicaciones, los autores principales, el listado de revistas donde se publicaron los artículos y las calificaciones de las revistas. Los resultados mostraron que los artículos sobre huevos comerciales han disminuido en los últimos años, siendo la detección y contaminación de Salmonella el tema más abordado (30%). Además, se pudo observar que las publicaciones están más concentradas en el Sureste (35%) y Nordeste (15%). El autor con más publicaciones sobre el tema fue Pinto, A. T., siendo el Archivo Brasileño de Medicina Veterinaria y Zootecnia el más publicado sobre el tema (20%). Finalmente, todos los artículos encontrados fueron publicados en una revista con cualidades expresivas superiores a B3, siendo A2 el que más cubrió las publicaciones, totalizando un 40%, demostrando la importancia del tema. Además, se concluye que hay regiones donde la investigación sobre la producción comercial de huevos aún no está muy extendida. Además, este estudio presenta un panorama actual de la producción de huevos comerciales en Brasil, brindando posibilidades para ampliar el conocimiento a través de estudios en áreas y temas poco investigados. O objetivo neste estudo foi apresentar uma revisão sistemática e análise cienciometrica sobre produção de ovos comerciais no Brasil. Para a revisão sistemática, selecionou-se artigos direcionados aos subtópicos descritos. Em contrapartida, a análise cienciometrica foi realizada considerando os artigos indexados nas plataformas CAPES, SCIELO, SCORPUS e WEB OF SCIENCE. Posteriormente, os artigos encontrados foram analisados e agrupados quanto ao número de publicações por ano, temática abordada nas publicações, regiões onde ocorreram as publicações, principais autores, lista das revistas onde os artigos foram publicados e o qualis dos periodicos. Os resultados demostraram que os artigos sobre ovos comerciais diminuíram nos últimos anos, sendo a detecção e contaminação de Salmonella a temática mais abordada (30%). Além disso, foi possível observar que as publicações se concentram mais na região Sudeste (35%) e Nordeste (15%). O autor que mais teve publicações sobre a temática foi Pinto, A. T., sendo o periódico Arquivo Brasileiro de Medicina Veterinária e Zootecnia o que mais publicou sobre o assunto (20%). Por fim, todos os artigos encontrados foram publicados em revista com qualis expressivos superiores a B3, sendo A2 o que mais contemplou as publicações, totalizando 40%, demostrando a importância da temática. Ademais, conclui-se que existem regiões onde a pesquisa sobre a produção de ovos comercias ainda é pouco difundida. Além disso, este estudo apresenta um panorama atual da produção de ovos comercias no Brasil, proporcionando possibilidades de expansão de conhecimento através de estudos em áreas e temas poucos pesquisados.

The objective of this study was to report the diseases that occur in calves up to one year of age, establishing the main epidemiological factors associated with the occurrence of these diseases. The breeding phase is considered the most sensitive of the entire production system. Calves, especially in the first weeks of life, are more susceptible to acquiring diseases, being important attention by the caregivers on basic care, thus avoiding the highest mortality rates that occur mainly until the weaning, with the most frequent problems being navel infections, diarrhea, pneumonia, verminoses and parasitic sorrows. In view of the above, this study made it possible, through analyzes of scientific studies, to conclude that neonatal care is extremely necessary to prevent the animal from being affected by some type of illness, environmental conditions and inadequate sanitary management associated to the lack of measures prophylactic factors are determinant for the increase in the number of sick animals. On the other hand, the correct nutritional management, prevention and control of these diseases favor to improve health, allowing the animal to express its maximum potential for production and reproduction throughout its life, contributing to a positive economic return, reducing expenses with treatments and with future epidemics. El objetivo en este estudio fue relatar las enfermedades que ocurren en becerros hasta un año de edad, estableciendo los principales factores epidemiológicos asociados a la ocurrencia de esas enfermedades. La fase de cría se considera la más sensible de todo el sistema de producción. Los becerros, principalmente en las primeras semanas de vida, son más susceptibles de adquirir enfermedades, siendo importante la atención por los cuidadores en cuanto a cuidados básicos, de esta forma evitando las tasas más altas de mortalidad que ocurren principalmente hasta el desmane, siendo que los problemas más frecuentes son las infecciones del ombligo, diarreas, neumonías, verminosis y tristezas parasitarias. En el presente estudio, este estudio posibilitó por medio de análisis de trabajos científicos, concluir que los cuidados neonatales son extremadamente necesarios para evitar que el animal sea acometido por algún tipo de enfermedad, las condiciones del ambiente y el inadecuado manejo sanitario asociado a la escasez de medidas profilácticas son determinantes para el aumento del índice de animales enfermos. Por otro lado el manejo nutricional correcto, prevención y control de esas enfermedades favorece para mejorar la salud, posibilitando que el animal exprese su máximo potencial para la producción y reproducción durante todo su período de vida, contribuyendo con un retorno económico positivo, disminuyendo los gastos con tratamientos y con futuras epidemias. O objetivo neste estudo foi relatar as enfermidades que ocorrem em bezerros até um ano de idade, estabelecendo os principais fatores epidemiológicos associados à ocorrência dessas enfermidades. A fase de cria é considerada a mais sensível de todo o sistema produção. Os bezerros, principalmente nas primeiras semanas de vida são mais suscetíveis de adquirir doenças, sendo importante a atenção pelos tratadores quanto a cuidados básicos, dessa forma evitando as mais altas taxas de mortalidade que ocorrem principalmente até o desmane, sendo que os problemas mais frequentes são as infecções do umbigo, diarréias, pneumonias, verminoses e tristezas parasitárias. Diante do exposto, este estudo possibilitou por meio de análises de trabalhos científicos, concluir que os cuidados neonatais são extremamente necessários para evitar que o animal seja acometido por algum tipo de enfermidade, as condições do ambiente e o inadequado manejo sanitário associado á escassez de medidas profiláticas são determinantes para o aumento do índice de animais adoecidos. Por outro lado o manejo nutricional correto, prevenção e controle dessas doenças favorecem para melhorar a saúde, possibilitando que o animal expresse o seu máximo potencial para a produção e reprodução durante todo seu período de vida, contribuindo com um retorno econômico positivo, diminuindo os gastos com tratamentos e com futuras epidemias.
