Protecting livestock from the stress due to Rising temperatures Heat stress casts a shadow over the performance and profitability of livestock production. Unfortunately, farmers cannot always measure precisely the losses associated with this insidious threat, even though studies have confirmed the high cost associated with it. For the U.S. market, the yearly losses have been …

The risk of oxidative stress for high prolific sows and the impact on the Litter livability High prolific sows have high energy needs to cover the fetal development during late gestation, but also to ensure a right lactation performance. The animals endure a stronger metabolic activity which generates intense free radical production. This is the …

Free radicals, the result of the Respiratory process Free radicals are products from the respiratory process. They are highly reactive and can induce important oxidative damage in the organism, leading to an impairment of bio-logical functions. Antioxidants are defense molecules used by the animal to fight against these reactive species. They can be produced by …

Detrimental effects of heat stress in Livestocks Heat stress has detrimental effects in livestock. Excessive thermal stress around parturition can have detrimental effects on reproduction success and litter growth in swine. Antioxidants are commonly used in various species to limit oxidative stress caused by excess environmental heat. Grape polyphenols have been extensively studied for the …

What are Polyphenols? Polyphenols exist in a majority of plants, but not all of them have the same properties. This broad classification is displayed in various categories such as phenolic acids, stilbenes, flavonoids and lignans for which there are other subcategories. Therefore, the profiles of polyphenols and their associated properties differ greatly between those encountered …

Last August 2022, in Thessaloniki (Greece) Doctor Bui (DVM, Nor-Feed R&D team) shared new data obtained with our encapsulated grape extract during the 70th International Congress and Annual Meeting of the Society for Medicinal Plant and Natural product research (GA). Rumen-by-pass formula of Nor-Grape® to protect active molecules from Ruminal retention Natural grape extract constituted …
Colostrum quality and Oxidative stress During the peripartum period, the massive modulation in metabolism, physiology, immunity, etc., frequently generates the overproduction of reactive oxygen species (ROS), which causes oxidative stress [1]. The negative correlation between maternal oxidative imbalance and quality of colostrum has been confirmed by several studies. Some studies have shown that the supplementation …
Weaning in piglets: A critical period Piglets are fragile animals at birth as they have to build their immune system after farrowing through lactation and especially through colostrum ingestion. This building of the immune system must then continue during weaning, which is a critical period in the life of piglets that may be associated with …
