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 …

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 …
Improving the use of pigments in poultry Pigmentation has always been identified as being a quality indicator for chicken products worldwide. If we look at broilers, their yellow skin is traditionally associated to a free range and a corn feed diet. While in laying hens,the yellowness intensity of egg yolk is associated to its nutrients‘ …
Consider the Antioxidant system Antioxidant diversification is essential to improve heat stress resilience and tackle the oxidative stress issue. In livestock, certain polyphenols from grape extracts allow to preserve a high level of performance and help combat the negative effects of heat stress. Looking at the metabolism of livestock animals, they all share a very …
