Abstract In recent years, nanoparticles have become a fashionable subject of research due to their sizes, shapes, and unique intrinsic physicochemical properties. particular for the last 5 nano-Se has received tremendous attention in terms its production, characteristic, possible application poultry/animal science medical sciences. Indeed, Nano-Se is shown be potential source Se nutrition. However, there an urgent need address questions related absorption, assimilation, metabolism. It not clear at present if major biological effects are Se-protein synthesis, direct antioxidant/prooxidant effects, or both. necessary understand how metallic can converted into H 2 further SeCys incorporated selenoproteins. The aforementioned issues must resolved before finds way animal/poultry production as feed supplement clearly this warrants investigation.

Poultry, Journal Year: 2022, Volume and Issue: 1(4), P. 246 - 277

Published: Nov. 7, 2022

Oxidative reactions in premixes or final-compound feed pose considerable challenges to the poultry industry, both terms of rancidity reducing palatability and shelf life vivo oxidative stress negatively impacting animal performance. Whilst there has been broad awareness oxidation for many years, recognition impact on industry grown past twenty years. The appearance woody breast associated muscle meat myopathies led a rapid increase research output reactions. widely demonstrated damage tissue, lipids, DNA, is thought be linked conditions such as leaky gut, coccidiosis, ascites, amongst others. use dietary antioxidants found protect from ameliorate some detrimental effects with stress, including improving performance, increasing antioxidant capacity, mitigating heat transport stress. Therefore, aim this review provide insight into process in-feed summary benefits different kinds well their potential added value, based findings reported within all scientific literature.

Essential Oils as a Dietary Additive for Laying Hens: Performance, Egg Quality, Antioxidant Status, and Intestinal Morphology: A Meta-Analysis

Agriculture, Journal Year: 2023, Volume and Issue: 13(7), P. 1294 - 1294

Published: June 25, 2023

This meta-analysis aimed to evaluate the effects of dietary supplementation with essential oils (EOs) on egg production and quality, antioxidant status in blood serum, intestinal morphology laying hens. The data used were obtained from 38 peer-reviewed publications. effect size was evaluated by weighted mean differences (WMD) between experimental treatments (diets added EOs) control without EOs). EO increased (p < 0.001) (WMD = 2.171%), weight 0.636 g), mass 1.679 g/d), decreased feed conversion ratio −0.074 g/g; p 0.001).

Protective effect of glutathione S-transferase enzyme activity against aflatoxin B1 in poultry species: relationship between glutathione S-transferase enzyme kinetic parameters, and resistance to aflatoxin B1

Poultry Science, Journal Year: 2021, Volume and Issue: 100(8), P. 101235 - 101235

Published: May 4, 2021

Comparative studies designed to investigate the role of glutathione S-transferase (GST) activity on enzyme catalyzed trapping aflatoxin B1-8,9-epoxide (AFBO) with glutathione, and relationship B1 (AFB1) resistance have not been conducted in poultry. Hepatic cytosolic fractions chickens, quail, turkeys ducks were used measure vitro enzymatic parameters maximal velocity (Vmax), Michaelis-Menten constant (Km) intrinsic clearance (CLint) for GST activity. AFB1 ranged from 2.0 157.5 µM AFB1-GSH produced was identified quantitated by HPLC. Significant differences found Vmax values, being highest followed turkeys. The Km values also significantly different, chickens < quail. Chickens had higher CLint value contrast ducks.

Abiotic stressors in poultry production: A comprehensive review

Journal of Animal Physiology and Animal Nutrition, Journal Year: 2024, Volume and Issue: unknown

Published: Aug. 12, 2024

Abstract In modern animal husbandry, stress can be viewed as an automatic response triggered by exposure to adverse environmental conditions. This range from mild discomfort severe consequences, including mortality. The poultry industry, which significantly contributes human nutrition, is not exempt this issue. Although genetic selection has been employed for several decades enhance production output, it also resulted in poor resilience. Stress manifested through a series of physiological reactions, such the identification stressful stimulus, activation sympathetic nervous system and adrenal medulla, subsequent hormonal cascades. While brief periods tolerated, prolonged have more consequences. For instance, extreme fluctuations temperature lead accumulation reactive oxygen species, impairment reproductive performance, reduced immunity. addition, excessive noise slaughterhouses linked altered bird behaviour decreased efficiency. Mechanical vibrations shown negatively impact meat quality broilers during transport well egg hatchability hatcheries. Lastly, heavily influenced light intensity regimens, inadequate management result deficiencies, visual anomalies, skeletal deformities, circulatory problems. there growing body evidence demonstrating stressors on physiology, disproportionate representation research. Recent studies focused chronic heat stress, reflecting current interest scientific community climate change. Therefore, review aims highlight major abiotic elucidate their underlying mechanisms, addressing need comprehensive understanding diverse contexts.
