The El Niño represents a substantial threat to pastures, affecting the availability of water, forage and compromising sustainability grazing areas, especially in northern region Brazil. Therefore, objective this study was characterize thermographic profile three production systems Eastern Amazon, conducted on rural cattle farm Mojuí dos Campos, Pará, Brazil, between August November 2023. experiment involved livestock systems, including traditional, silvopastoral integrated, with different conditions shade access bathing area. An infrared (IRT) camera used, recording temperatures zones, such as areas trees, pastures exposed pastures. highest mean (p = 0.02) were observed full sun from November. On other hand, lowest average recorded shaded by chestnut trees (Bertholletia excelsa). temperature ranges found sunny areas. pasture sun, while < 0.0001). interaction treatments revealed significant differences 0.0001), native showing an 35.9 °C, lower than grasses soil, which reached 61.2 °C. This research concludes that, under Brazil nut had temperatures, demonstrating effectiveness shade. Native compared showed ability create cooler environments, highlighting positive influence species sheep, goats cattle.

Environmental changes and the spread of non-native species significantly affect wetland ecosystems, such as coastal lagoons. This study investigates effects increased temperature on parental care behaviour, specifically pleopod fanning, in ovigerous females following three Palaemon species: global invader macrodactylus Mediterranean native elegans adspersus. Under controlled laboratory conditions, we measured beats per minute across a gradient to assess species-specific responses. Our results showed significant inter-species differences fanning with P. exhibiting lowest beat rate overall. Temperature strong positive correlation all species, whereas dissolved oxygen negatively correlated adspersus macrodactylus. Interestingly, exhibited unique response compared its congeneric because it was only among those studied that did not show negative between concentration. These findings have enhanced our understanding behavioural responses invasive environmental alterations, providing valuable insights into how interact their changing environments.

Thus, this review aims to deepen the understanding of buffalo farming in Amazon, presenting quality and nutritional value meat liver. This information serves as a subsidy improve practices related breeding system, nutrition, health sustainability associated with aquatic buffaloes. For this, databases was carried out using descriptors "nutritional meat", liver" "buffalo Amazon". consumption foods derived from buffaloes has important for human consumption. In view it is possible conclude that nutrition these animals influenced by biodiversity giving unique characteristics its products, also highlighting importance carrying research potential use species strengthen economy region.

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 climatic conditions and supplementation based on palm kernel cake, thermoregulation crossbred buffaloes in eastern Amazon. research carried out at Embrapa Amazônia Oriental (01°26′ S 48°24′ W), Belém, Pará, lasted 12 months (representing entire year).

The objective was to characterize the pastures by grazing cycle, as well evaluate performance of buffaloes in intensive rotational a silvopastoral system eastern Amazon supplemented with agro-industry co-products order cycles, composition fractions, and carcass yield. Fifteen non-castrated, crossbred water (Murrah × Mediterranean) were used. All animals used study clinically healthy weighed approximately 458 kg. grazed single group, supplementation (1% live weight—LW/day) divided into three treatments: control (control—conventional ingredients); Cocos nucifera coconut cake (Cocos nucifera) (coconut cake—70%); palm kernel (Guinean elaeis) (palm cake—70% cake). chemical forage is different each part plant, higher protein values leaves (11.40%) acid detergent fiber (ADF) stems (50.03%). Among ingredients supplement, corn has highest percentage indigestible (35.57%), most B3 (49.11%), Coco, B2 (51.52%).

There no difference daily weight gain yield, 1 kg/day 49.23%, respectively. Therefore, it can be concluded that including supplements based on by-products from oil agro-industries promotes yields compatible conventional supplements. Their use reduces production costs, optimizes utilization mass, enhances sustainability chain, and, therefore, recommended.
