Poultry gut health
The efficient conversion of feed into its basic components for optimal nutrient absorption is vital for both broiler and broiler breeder production and welfare. Gut health, an intricate and complex area combining nutrition, microbiology, immunology and physiology, has a key role to play. When gut health is compromised, digestion and nutrient absorption are affected which, in turn, can have a detrimental effect on feed conversion leading to economic loss and a greater susceptibility to disease. In addition, recent changes in legislation on the use of antimicrobials, differing feed requirements and more efficient birds highlight the need for a better understanding of gut function and gut health.
Over the last two decades, several types of gut health supporting additives have been shown to have at least the potential to improve gut health and animal performance and as such, to be applied as alternatives to antibiotics. Initial research on these products was largely focused on their direct ‘antimicrobial’ effect, as it was tempting to hypothesize that any successful alternative for antibiotics would need to have a similar (antimicrobial) effect. However, it becomes clearer...

The growing global livestock production is moving away from antibiotic growth promoters and coccidiostats, means that the industry will therefore face new challenges impacting gut health. As a consequence, gut health management has become a key focus in the livestock production. The role of betaine and its physiological functions Over the last years, the use of betaine in animal feed diets has moved from selective utilization, to that of a core ingredient in key feed...

INTRODUCTION Since the 1970’s, broilers have substantially improved in growth rate, breast-meat yield and efficiency of feed conversion (Dawkins and Layton, 2012). Feed conversion ratio (FCR), calculated as the ratio of feed consumed to weight gained, is a widely used performance measure, representing how efficiently the feed is utilized and converted into body mass (Stanley et al., 2012). The extraction of energy...

Introduction To help customer’s understanding, we were gathering some recent commercial trials data from Korea. In Korea, we have recommended to use AQUABLEND AVIAN during day 1-3 in drinking water or anytime at veterinarian’s discretion. At present, we have many customers who are using AQUABLEND AVIAN in broilers, layers, ducks and breeders. At 35-36 days old, AQUABLEND AVIAN-treated birds have shown around...

1. Introduction Microbiota is defined as the microbial community, including commensal, symbiotic and pathogenic microorganisms, which colonise different areas of animals and have an important influence on animal health, productivity and disease control [1–9]. Hence, the presence of beneficial microbiota plays an important role in production, protection from pathogens, control of epithelial cell proliferation and differentiation, detoxification (controlling the behavioural...

The average commercial broiler consumes 3.2 kg of feed over 35 days to achieve 1.8 kg of body weight, compared with more than 20 kg of feed over 112 days to attain the same weight in the 1920’s. This improvement in poultry growth performance has been achieved, in large part, through advances in animal genetics, health, and nutrition, including the use of in-feed antibiotic growth promoters such as virginiamycin and bacitracin methylene disalicylate. Dietary antibiotics have been used...

Probiotics offer one alternative to antibiotic growth promoters as they have been shown to improve the development and maintenance of a stable gut microbiome in poultry, which leads to reduced enteric disease and improved growth performance. Therefore, the objective of this study was to delineate the effects of Bacillus subtilis DSM 32315 (BS DSM32315) on intestinal morphology, microbial composition and performance in broiler chickens. A total of 240 Arbor Acre (AA) male birds were...

It's not always that the high performance brings production stress to poultry, it's the way you deal with it. The high performing animals and feed is need of the competitive world. The crucial mission is to support them adequately to perform. Some choices are available as feed additives to control the production stress. But they are limited by their stability, safety and...

Dietary antibiotics have been used in the food animal industry for more than 60 years, not only to control infectious diseases, but also to increase feed efficiency and improve growth performance. In chickens, subtherapeutic, in-feed antibiotics can increase body weight gain up to 8% and decrease the feed conversion ratio (feed intake/body weight gain) up to 5%, both compared with an antibiotic-free diet. Antibiotics overuse and abuse on a global scale have led to the emergence of multi-drug...
