I. INTRODUCTIONConsumer demand for organic and free-range poultry products is driving the commercial egg industry away from conventional housing systems towards free-range housing systems that allow birds access to the outdoors. Whilst these systems are considered higher welfare, they also carry more health risks that can impact the intestinal health of the bird, such as greater exposure to parasi ...

Amine Benarbia (NOR-FEED)     Eimeria spp. completes its life cycle within the host’s gastrointestinal tract. its reproduction has been known to damage enterocytes, leading to decreased growth performance and welfare in chickens. Controlling the reproduction cycle and limiting oocyst excretion could explain the observed efficacy of steroidal saponin-based standardized premixtu ...

The livestock industry is currently confronted with stringent regulations limiting the use of antibiotics, along with growing challenges from resistant pathogenic bacteria. These factors have prompted an urgent need to seek alternative strategies that can effectively promote animal health and optimize feed efficiency. In this context, postbiotics have gained significant attention as a modern solut ...

1. IntroductionThere is considerable interest in the successful development of low protein diets for broiler chickens, which axiomatically contain high inclusions of supplemental amino acids. This is because low protein diets have the potential to generate economic, environmental and bird welfare advantages.Formulation of low protein diets are usually achieved by decreasing soybean meal inclusions ...

1. IntroductionCorn ranks among the most globally cultivated cereals, with the production of more than 1200 million tons in the 2022/2023 harvest, mainly concentrated in the United States, China, and Brazil [1]. In Brazil, corn is the second most produced grain, following soybeans. For the 2023/2024 harvest, the estimated production in Brazil will exceed 118 million tons [2]. In the Brazilian mar ...

Avian Influenza (AI), commonly known as bird flu, is a highly contagious viral disease affecting poultry and other birds. It poses a serious threat to the poultry industries, causing significant economic losses due to high mortality rates, trade restrictions, and culling measures. The disease is particularly prevalent in Southeast Asia, where dense poultry farming and live bird markets facilitate ...

1. IntroductionIn poultry nutrition, soybean meal is one of the main protein sources used due to several factors such as the percentage of crude protein (CP), its good amino acid profile, and its bioavailability [1]. However, the existence of antinutritional factors (AF) in soybean meal has been shown to have a considerable effect in reducing the bioavailability of elements in this product, such a ...
