Recent publications by Verhelle und Saremi (2024) and Westreicher-Kristen et al. (2025) reported broiler feeding experiments to evaluate the nutritional value of guanidinoacetic acid (GAA) in comparison to L-arginine (L-Arg). Basically, reported broiler performance responses are in agreement with expectations based on literature. However, the authors drew misleading conclusions on the efficacy of ...

IntroductionHigh levels of production and efficient feed conversion are the need of the modern livestock industry which to a certain extent could be achieved by using specific feed additives. Feed additives are of great interest in the poultry industry due to their property to promote growth and performance. Common feed additives used in poultry diets include antibiotics, antioxidants, emulsifiers ...

Introduction. The indigestible soy galactooligosaccharides (GOS) stachyose and raffinose are considered anti-nutritional factors in poultry because they decrease the metabolizable energy of soy protein (Leske et al., 1993) and decrease performance (Jiang et al., 2006). The objective was to investigate if there was a dose-response effect of increasing levels of the soy GOS raffinose and stachyose i ...

IntroductionThere is a mandatory requirement for crude protein (CP) in broiler chicken diets ranging from 180 to 230 g/kg. When dietary energy density is not limiting, the quality and quantity of dietary CP dictates birds’ growth performance. The digestibilities of protein and amino acids are pivotal to the quality of the inclusion of any feedstuff in diets for chicken-meat production. ...

INTRODUCTIONIt is imperative to identify factors that inhibit the digestibility of nutrients for successful commercial poultry production. The non-starch polysaccharides (NSP) like substances of hemicellulose, cellulose, and pectin can reduce nutrient digestibility in poultry (Choct, 1999). Among the NSP, β-mannans are a group of hemicelluloses, which are present in many ingredients used for ...

The following article is a special collaboration from AFMA (Animal Feed Manufacturers Association) www.afma.co.zaWe thank their kind support.SummaryEnzymes have been used in the feed industry for more than 30 years. Traditional applications have included improving the digestibility and bird performance of ingredients such as barley and wheat. As our understanding of the anti-nutritive factors that ...

A study was conducted to investigate whether the functional oligosaccharides released in situ as a consequence of fibre-degrading enzyme application ameliorate the severity of necrotic enteritis (NE) in broilers offered wheat- or maize-based diets. Day-old Cobb 500 mixed-sex broilers (n = 1536) were assigned to a 2 × 2 × 4 factorial arrangement of treatments, with six replicates per tr ...
