Abstract Livestock production supports economic growth, jobs and nutrition, but contributes to is vulnerable climate change. A transition thus needed for livestock systems become more sustainable resilient, with clear positive effects on the Sustainable Development Goals. It unclear, however, where global community should invest support this We identified priority geographies system investments in 132 low- middle-income countries (LMICs), at mid- low latitudes. Our results show that adaptation mitigation goals are inextricably linked vast majority of these countries. An equal weighting indicators suggests top five investment priorities India, Brazil, China, Pakistan Sudan. Across LMICs, act as critical control points sector’s interactions system, land livelihoods.

Abstract Human-induced climate change significantly alters the spatiotemporal characteristics of zones, which drives agricultural land use and ecosystem change. However, detectability shifting zones rate time changes has yet to be adequately addressed at regional-to-local scale. We mapped analyzed temperature precipitation across Kenya during past four decades, linked those shifts in geographic distribution arrangement regional scales. observed an approximate 1 °C increase average annual over 40-year period. A total 76,346 km 2 shifted from cooler hotter while 1298 zones. Tropical regions expanded 91 93%, with 13,000 alpine temperate tropical regions.

Heat stress causes functional and metabolic alterations in different cells tissues. There are several pathomorphological changes biomarkers associated with head load adaptive productive organs of livestock. stress-induced histopathological livestock were categorized as degenerative (fatty degeneration, steatosis, hydropic degeneration), necrosis (pyknosis, fibrosis), circulatory disturbances (hyperemia, edema, hemorrhage, congestion, thrombosis, ischemia), growth (hyperplasia, atrophy) focal/diffuse inflammation (vascular changes, exudation). Upon immunohistochemical analysis, the identified growth-related HSP70, HSP60, GABA, GABAAR, GABABR, HSP90, GnRH, LH, FSH, m6A, Nrf2, C/EBPβ. The reproductive Bax, Bcl-2, Caspase-3, HSPB9, HSPB10, HSF1, HSP40, T, E2, Cyt-C, CAT, BCL2L1, VEGF. immune CD3+ T cells, CD4+ CD8+ Bcl-2. All these could serve reliable variables heat assessment Further, NPY, HSP27, NF-κB, AQP2, Insulin, CD172a, EGF, AQP1, AQP3, AQP4, AQP5, CRYAB, GHR, 5-HT, CCK, GLP-1 stress-related that help assessing climate resilience a species improving understanding about mechanisms. Among biomarkers, HSP70 was established to be ideal cellular biomarker for scaling response Thus, examining heat-stressed organ histopathology identifying markers by immunohistochemistry may lay foundation screening climate-resilient breeds challenging climatic scenario. such an approach developing concepts combat detrimental consequences ensure sustainability production.

Опубликована: Апрель 10, 2023

Heat stress is one of the most stressful events in livestock life, negatively impacting animal health, productivity, and product quality. Moreover, negative impact heat on quality has recently attracted increasing public awareness concern. The purpose this review to discuss effects physicochemical component meat ruminants, pigs, rabbits, poultry. Based PRISMA guidelines, research articles were identified, screened, summarized based inclusion criteria for safety Data obtained from Web Science. Many studies reported increased incidences welfare Although impacts can be variable depending severity duration, exposure animals (HS) affect Recent have shown that HS not only causes physiological metabolic disturbances living but also alters rate extent glycolysis postmortem muscles, resulting changes pH values carcasses meat. It been a plausible effect antioxidant activity.

Опубликована: Май 26, 2023

With the recent trend of global warming, HS-instigated diminishing could extremely jeopardize animal health, productivity, and farm profit. Marjoram essential oil (MEOE) is a worthy source wide range phytogenic compounds that may improve heat tolerance, redox inflammatory homeostasis, immunity newly weaned rabbits, specifically if included in diets nano form. One hundred rabbits were randomly distributed into four homogeneous groups. The first group (control group) received basal diet without supplementation. In contrast, other three groups supplemented with 200 (MEONE200), 400 (MEONE400), 800 (MEONE800) mg MEONE/kg diet, respectively. Among MEONE-treated control groups, MEONE400 showed highest (p < 0.001) growth performance traits, including final body weight, average daily gain, feed efficiency, index. Compared to control, all MEONE-supplemented possessed lower rectal temperatures respiration rates, recording lowest values group. oxidative stress biomarkers immunoglobulins G M significantly improved MEONE800 compared MEONE200 addition MEONE (400 or mg/kg) decreased concentrations serum interleukin-4 = 0.0003), interferon gamma 0.0004), tumor necrosis factor-α 0.0001) but elevated activity nitric oxide, amyloid A lysozyme.
