Summary: Scientific evidence shows that plant feed additives (PFA) can be a viable alternative to synthetic antioxidant vitamins in poultry nutrition. PFA, represented by plants, essential oils, plant extracts, and by-products from herbal or crop processing, have been increasingly used in the feed industry due to their antimicrobial and antioxidant effects. A systematic literature review comparing the effects of PFA and synthetic vitamins on poultry products in the past 20 years revealed that PFA have positive impacts on oxidative stability, organoleptic characteristics, and fatty acids profile without specific effects on performance. The effects of PFA are variable but often similar to those of vitamin E, suggesting the opportunity for a partial substitution in poultry diets.

Summary: The main stress factors that disrupt homoeostasis in poultry are environmental, nutritional, microbiological, and managing. Among these factors, high ambient temperatures have a significant impact on poultry production and health. High temperatures lead to oxidative stress and damage the antioxidant capacity of poultry. Nutrients such as vitamins E and C, selenium, and curcumin play a crucial role in enhancing the antioxidant defence system and mitigating the detrimental effects of heat stress.

Summary: This study found that dietary addition of chromium propionate can improve the laying rate and yolk color score of laying ducks, as well as reduce the feed/egg ratio. Moreover, high doses of chromium propionate increased albumen height and the Haugh unit, decreased serum cortisol and heat shock protein-70, increased serum insulin and total protein, and enhanced antioxidant enzyme activities.

Summary: This review article discusses the effects of betaine as a feed additive on poultry. Different concentrations of betaine can improve performance, feed conversion ratio, and carcass traits in poultry, and also have osmoregulatory, anticoccidial, immune-modulatory, and heat-stress alleviation activities.

Summary: This study investigated the prevalence of plasma micronutrient abnormalities and their impact on clinical outcomes and treatment complications in paediatric cancer patients. The results showed a high prevalence of micronutrient abnormalities, especially deficiencies in vitamin A and zinc, along with low selenium levels predicting adverse clinical outcomes and treatment complications. Further research and clinical trials are needed to better understand and address these micronutrient issues in paediatric cancer care.

Summary: This study aimed to evaluate the association between antioxidant consumption and lung cancer incidence. Data from the PLCO cancer screening trial were used, and a total of 98,451 participants were included. The results showed that antioxidant intake from food sources was associated with a lower risk of lung cancer, while no effects were observed in the supplemental group. It is recommended to consume a combination of various antioxidants for potential benefits.

Summary: The objective of this research was to evaluate the thermal exchanges, physiological responses, productive performance and carcass yield of Guinea Fowl under thermoneutral conditions and under thermal stress. The results showed that when the air temperature increased, the physiological responses and water consumption of the guinea fowl increased, but it did not significantly affect the productive performance and carcass yield.
