Dairy cows may suffer thermal stress during the colder seasons especially due to their open-air housing systems. Free water temperature (FWT) and feed (FT) are dependent on ambient (AT) can be critical for maintaining body reticulorumen (RT) in cold conditions. The objective of this study was determine effects FWT FT RT fluctuations, AT drinking eating behaviors late-lactation exposure. Data were collected from 16 multiparous lactating four 6-d periods autumn winter seasons. (224 ± 36 days milk; mean SD) had an average milk yield (MY) 24.8 4.97 kg/d 38.84 0.163 °C.

Hypothalamic Neuromodulation of Hypothermia in Domestic Animals

Animals, Journal Year: 2024, Volume and Issue: 14(3), P. 513 - 513

Published: Feb. 4, 2024

When an organism detects decreases in their core body temperature, the hypothalamus, main thermoregulatory center, triggers compensatory responses. These responses include vasomotor changes to prevent heat loss and physiological mechanisms (e.g., shivering non-shivering thermogenesis) for production. Both types of require participation peripheral thermoreceptors, afferent signaling spinal cord efferent pathways motor and/or sympathetic neurons. The present review aims analyze scientific evidence hypothalamic control hypothermia central that are triggered domestic animals.

Efficient farm practices are crucial for livestock health and performance, cold stress is a major challenge cattle in winter. This study aimed to preliminarily investigate the effects of warm water intake winter on growth thermal indicators, serum hormones metabolites, rumen fermentation parameters, fiber degrading enzyme, microflora yellow during Eight Wandong Bulls (Bos taurus) were divided into two groups: group C, which received (6.36 ± 1.99 °C), E, (32.00 3.12 °C) 30 d. The results showed that significantly increased ADG (p = 0.024) DMI 0.046) decreased 0.047) ratio feed weight gain.

Enhanced propionate and butyrate metabolism in cecal microbiota contributes to cold-stress adaptation in sheep

Microbiome, Journal Year: 2025, Volume and Issue: 13(1)

Published: April 24, 2025

During cold stress, gut microbes play crucial roles in orchestrating energy metabolism to enhance environmental adaptation. In sheep, hindgut ferment carbohydrates generate short-chain fatty acids (SCFAs) as an source. However, the mechanisms by which and their metabolites interact with host facilitate adaptation environments remain ambiguous. Herein, we simulated a winter environment (- 20 °C) provided rationed diet compare between Hulunbuir Hu sheep. Our findings show that exposure enhances SCFA sheep cecum. acetate, butyrate, total concentrations increased, whereas propionate butyrate notable increase SCFAs. Notably, concentration was higher than under stress. Following exposure, proinflammatory cytokine IL-1β levels increased both breeds. addition, showed IL-10, exhibited elevated secretory IgA levels. The cecal microbiota responded differently, no changes alpha beta diversity, considerable alterations. abundance of fungi, specifically Blastocystis sp. subtype 4, decreased, several Lachnospiraceae species (Roseburia hominis, Faecalicatena contorta, Ruminococcus gnavus) involved increased. Pathways related carbohydrate metabolism, such starch sucrose galactose pentose glucuronate interconversions, were upregulated. Treponema bryantii, Roseburia 499, Prevotella copri upregulation pathways amino acid metabolism. Cold node connectivity within symbiotic networks breeds, network vulnerability microbial community decrease influence stochastic processes on assembly, corresponding role selection. Conversely, shift evident Further transcriptomic analysis revealed distinct regulatory protein synthesis, thermogenesis substantially By contrast, immune conservation through reduced ribosome synthesis. Correlation indicated holds central position networks, exhibiting more complex tightly regulated involving SCFAs, microbiota, functions, transcriptomes. Partial least squares path modeling altered transcriptomes affecting SCFAs cytokines. this study suggest acetate fermentation rely tissue for exhibit diversity function, leading This may promote physiological innate defense, balancing heat loss enhancing
