IntroductionInert digestibility index markers are the anchor of many feeding trials designed to analyse nutrient utilisation and amino acid digestibility along the gastrointestinal tract of animals. Marker use is widely accepted as a method less laborious than total tract retention.Additionally, it enables the determination of digestibility along intestinal sections in ruminant and non-ruminant an ...

IntroductionOver the years, nutritionists have studied several ways to determine the ideal dietary supply of essential amino acids to optimize poultry performance. However, considering only performance objectives without taking into account economic factors may not reflect maximum profitability, since optimizing performance is not always viable (Pack et al., 2003). An economic approach to determin ...

INTRODUCTIONZinc (Zn) is an essential trace element in all living systems – from bacteria, plants and animals to humans – and plays an important role in various biological activities in animals, especially in fast-growing poultry (Liu et al., 2011). Poultry diets are commonly supplemented with Zn since many feed ingredients are marginally deficient in this trace element (Bao et al., 20 ...

Litter management is a cornerstone of sustainable poultry production, directly impacting bird health, environmental safety, and community acceptance. Among the many challenges faced by poultry producers, fly infestation and persistent odour remain the most difficult to control. These issues not only affect farm hygiene but also pose risks of disease transmission, regulatory scrutiny, and strained ...

1. IntroductionPast reviews describe recent progress and future perspectives on the use of next-generation sequencing (NGS) in veterinary medicine. Key advances in mammalian NGS-based diagnostics include the adoption of different types of sequencing platforms and the development of specific applications of NGS for the different mammalian hosts common for human and veterinary medicine. These advanc ...

I. INTRODUCTIONThe digestive dynamics of starch and protein are considered pivotal to broiler performance (Liu and Selle, 2015). Moreover, it was proposed that the rates of starch digestion and glucose absorption exceed the rates of protein digestion and amino acid absorption and this asynchrony in digestive dynamics compromises the performance of broiler chickens. If so, it follows that the provi ...
