Growth of the modern broiler is very adaptable to a vast range of diet nutrient densities, and so formulation matrices are greatly impacted by prevailing economic situations. The broiler still eats quite precisely to its energy needs and alters its feed intake in response to variable diet energy level. For example, 25-35d broilers can be fed diets a low as 2850 kcal/kg or as high as 3500 kcal/kg a ...

1. IntroductionInfluenza A virus (IAV) is an enveloped RNA virus, a member of the Orthomyxoviri dae family, and is known to infect humans, mammals, and birds [1]. The virus is subtyped based on the antigenic cross-reactivity and sequence identity of two surface glycoproteins, namely, hemagglutinin (HA) and neuraminidase (NA) [2]. Excluding the recently identified H17N10 and H18N11 in bats, 16 HA a ...

1. IntroductionThe misuse and overuse of antibiotics in humans and livestock animals are primary drivers of antimicrobial resistance [1,2], which is projected to become the leading cause of global human mortality by 2050 [1]. Consequently, the subtherapeutic use of medically important antibiotics for growth promotion and disease prevention in livestock has been banned in an increasing number of co ...

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 ...
