Summary: In this study, a bioclimatic zoning for dairy cattle in the Midwest region of Brazil was established using meteorological data. The impact of climate factors on milk production was estimated. The results showed three Temperature and Humidity Index (THI) classifications in the Midwest region throughout the year: 'normal', 'alert', and 'critical alert'. During spring and summer, a reduction in milk production of 1 to 2 kg was observed for cows with a daily production level of 25 kg, while cows with a daily production level of 10 kg showed no reduction in milk production.

Summary: As the Earth's climate warms, the frequency and severity of outdoor thermal conditions that threaten human life are increasing. To effectively prepare and adapt to this challenge, it is crucial to understand both the current baseline thermal conditions and how they will change in the future. However, current efforts to measure and model baseline thermal conditions have not fully considered the contributions of radiation and have been conducted at coarse temporal and spatial resolutions.

Summary: This study evaluated the dynamics of heat zones and their relationship with heat stress of weaner pigs during road transport in a tropical climate. The results showed that heat zones of different magnitudes occurred along the load, harmonized by ventilation dynamics. Weaners in the lower deck compartments were more susceptible to heat stress, while those in the upper deck compartments were more susceptible to physical stress and muscle exhaustion.

Summary: This study evaluated the behavior and thermal comfort of Girolando cows in the wettest period in the Eastern Amazon. The results showed that the cows spent more time in shaded areas, especially the dark-coated cows. Additionally, the light-coated cows spent more time in the sun while the dark-coated cows spent more time in the shade, which may negatively affect their health and zootechnical performance.

Summary: This study evaluates the thermoregulatory responses of goats fed with sugarcane in place of corn silage. The results show significant changes in rectal temperature and heart rate at different levels of sugarcane replacement, while skin temperature, respiratory rate, sweating rate, and body weight showed no significant differences. The observed higher heart rate and respiratory rate in the afternoon suggest that goats activate thermoregulatory mechanisms during the hottest times of the day. The study concludes that sugarcane partially influences the thermoregulatory responses of lactating Saanen goats.

Summary: This study found that cold-affiliated species in Andean tropical montane forests struggle to adapt their leaf functional traits to warming, while warm-affiliated species are able to adjust their traits from acquisitive to conservative strategies in response to cooling. This suggests that warm-affiliated species may have a competitive advantage under climate change, potentially leading to compositional shifts in these ecosystems.

Summary: The effects of housing system and stocking density on growth performance and carcase yield of broiler chickens in tropical conditions differed from temperate conditions. Low stocking density with outdoor access had enhancing effects on body weight, weight gain, feed intake, and feed conversion ratio, while outdoor access led to increased carcase yield.

Summary: Hyperuricemia is associated with renal and cardiovascular diseases, and its levels vary seasonally. This study investigated the correlation between urine acid (UA) levels and meteorological conditions, as well as the significance of these variations in clinical decision making. The Universal Thermal Climate Index (UTCI) was used to assess the impact of cold and heat stress on UA levels. The study found that UA levels differed based on age and gender, with a stronger correlation with age in females. Additionally, UA levels varied under different meteorological conditions, with higher levels in the autumn for females and differences in UA levels under cold and heat stress among the elderly. The UTCI was determined to be a suitable predictor of population variations in UA levels.

Summary: Animals respond to stimuli from their surroundings, and owls in captivity demonstrated different temperaments and glucocorticoid metabolite levels when challenged with predators. Adjectives indicating passiveness, vulnerability, and attentiveness were correlated with shyness, and owls with higher shyness scores showed higher post-predator challenge glucocorticoid metabolite levels. However, there were no significant differences in glucocorticoid metabolite levels before and after the predator challenge. This study confirms the relationship between shy temperament and adrenal response in nocturnal raptorial birds and provides non-invasive methods to assess the welfare of captive species.

Summary: Urban heat islands (UHIs) have negative impacts on the urban environment and outdoor thermal comfort (OTC) levels, especially in tropical cities. A study in Kuala Lumpur found that more than half of the urban dwellers experienced thermal discomfort, indicating strong thermal adaptive behaviors. Factors such as urban morphology, land cover, and human activity patterns also influence OTC levels. The findings highlight the importance of interventions like green infrastructure, UHI mitigation, and public awareness to improve outdoor thermal comfort.

Summary: This study investigated the effect of age at weaning of calves on non-esterified fatty acids (NEFA) and reproductive parameters of beef cows. The results showed that cows subjected to hyper-early weaning had better body weight and body condition score, and higher pregnancy rates. Additionally, NEFA levels decreased as the age at weaning decreased.

Summary: Beef production in subtropical areas relies mainly on extensive grazing systems. Energy supplementation during winter can help maintain desired production levels. This study found that adding 0.4% body weight of corn resulted in greater forage intake and improved performance in finishing steers.

Summary: This study examined the effects of three red seaweeds (Asparargopsis taxiformis, Mazzaella japonica, and Palmaria mollis) on in vitro fermentation, CH4 production, and adaptation using the rumen simulation technique (RUSITEC). The results showed that Asparargopsis taxiformis effectively inhibits CH4 production, but it requires an adaptation period and may restrict production performance.

Summary: This study evaluated the chemical and morphological characteristics of a nitrogen-fixing legume plant and assessed the benefits of including its fruits in ruminant diets composed mainly of tropical grasses. The results showed that the fruits of the legume plant had high protein and non-structural carbohydrates content and could serve as a natural energy and protein supplement for grazing ruminants during the dry season.

Summary: This study aimed to evaluate whether the variation in time spent feeding in the prepartum and postpartum periods may be used to detect the occurrence of metritis and subclinical ketosis (SCK) before the onset of the clinical symptoms at the postpartum. The results showed that the mean difference in feeding time between healthy and unhealthy animals was significantly higher during the postpartum period than during the prepartum period.
