Consumer demand for high quality and safe foods that will have a positive impact on their health has increased in recent years. Today, it is possible to meet those demands by combining the genetic potential of domestic animals and applying different feeding strategies. Nutrigenomics is one of the "omics" sciences that studies the interaction between nutrients and the genome together with their influence on metabolic and physiological processes in the body. While nutrition of domestic animals is solely based on studying the influence of nutrients on animal health and production traits, nutrigenomics integrates the fields of nutrition, genomics, molecular genetics and bioinformatics. By understanding the molecular relationships between different forms and/or concentrations of nutrients in feed and genes, it is possible to answer the question of how small changes in the diet of farm animals can produce a quality product with positive effects on human health. The aim of this article is to describe how the manipulation of adding different nutrients in the feed affects the expression of different genes in chicken and consequently alters their phenotype.

Background: Ration composition may significantly impact the nutrient absorption, duodenal parameters, intestinal health and feed efficiency of animals.
Objectives: The objective of this study was to analyse the impact of concentrate- and forage-based diets on essential morphological parameters of the duodenum, including villus height, villus width, crypt depth and goblet cell density, in three different lamb breeds.
Methods: Forty-five lambs, aged between 2.

Leptospirosis is a zoonotic disease caused by bacteria, affecting humans and a broad range of wild and domestic animals in diverse epidemiological settings (rural, urban, and wild). The disease's pathogenesis and epidemiology are complex networks not fully elucidated. Epidemiology reflects the One Health integrated approach of environment-animal-human interaction, causing severe illness in humans and animals, with consequent public health burdens.

The origin of domestic sheep (Ovis aries) can be traced back to the Asian mouflon (Ovis gmelini), in the Near East around 10 000 years ago. Genetic divergence within mouflon populations can occur due to factors such as geographical isolation, social structures, and environmental pressures, leading to different affinities with domestic sheep. However, few studies have reported the extent to which mouflon sheep contribute to domestic sheep in different regions.

Background: Gastrointestinal diseases in weaned piglets are a frequent cause of high morbidity and mortality in domestic pigs. The use of antibiotics is problematic due to increasing antibiotic resistance in bacterial populations, for which reason the use of suitable probiotics is highly recommended to maintain animal health and welfare.
Results: In this study, 57 strains of biologically safe lactic acid bacteria (LAB) and bifidobacteria originating from the gastrointestinal tract (GIT) of pigs were identified and characterized in terms of their probiotic properties for potential use in weaned piglets.
