INTRODUCTION The poultry industry is one of the main suppliers of animal protein worldwide, contributing both meat and eggs (1, 2). This is an industry in constant growth, as demonstrated by the United States Department of Agriculture (USDA). The USDA reported that 102.9 million tons of chicken meat were produced in January of 2020, which represents a 3.9% increase compared to the same period of the previous year (3). This increase is important, given that by 2050 the human...

INTRODUCTION Coccidiosis is the term used to describe an enteric disease caused by infection with one or more species of Eimeria (1), and has a high economic impact on the poultry industry worldwide (2, 3). The etiology of this intestinal disease are pathogenic Eimeria species that belong to the phylum Apicomplexa, in particular Eimeria maxima, E. tenella, and E. acervulina (1). Currently, seven species of Eimeria are known to infect chickens and differ in pathogenicity....

Introduction Soyabean meal is the most important source of dietary protein for poultry in South Africa and much of the world. The increased use of vegetable protein meals in animal feeds has been brought about through consumer pressure for more sustainable and welfare oriented animal protein production. The increased use of vegetable protein sources has highlighted the importance of protein quality and the methods used to control quality have increased proportionately....

INTRODUCTION Genetic selection for higher growth rate, and providing balanced diet and superior health care measures led to a higher body weight in commercial broilers. The birds that are being reared in open-sided poultry houses may lead to stress due to constant dynamic variations in temperature and humidity in the environment, which causes adverse effects on performance (Niu et al., 2009), meat quality and immune responses (Thompson and Scott, 1970). Further, heat causes a...

INTRODUCTION In recent years, interest in the welfare of hens has been increasing. The public and activist groups than by scientific evidence have influenced much of current European legislation on the welfare of laying hens more. These groups proposed that the European Union abolish the cage housing system by the enriched cage system (750 cm 2 of surface per bird); where the hens also have perches and nesting material (Bulmer y Gil, 2008). In this regard, in the...

INTRODUCTION Poultry are important Campylobacter reservoirs, with 50 to 70% of human infections related with food preparation flaws and the consumption of poultry products (FAO/WHO, 2001). Campylobacter is frequently detected in the digestive tract of poultry, and particularly of broilers older than three weeks of age, rapidly disseminating until market age (Stern & Robach, 1995; Jacobs-Reitsma, 1995). Campylobacter incidence in broilers may be related to management...

INTRODUCTION A healthy gut can help birds to gain optimum growth performance because gastrointestinal tract (GI) is meant for digestion/absorption of nutrients and immune response. The mucosal membrane of the intestine serves as a barrier between luminal digesta and tissues and requires a dynamic balance between different components of gut like epithelial cells, microbiome, and immune system cells for proper functioning. One of the most important components that affect...

Protein is the second most expensive nutrient in animal feed formulation, after energy. Diets which have excess crude protein can overload the gastrointestinal tract with excess amino acids and undigested protein (Apajalahti and Vienola, 2016), resulting in impaired feed efficiency, health and welfare issues as well as negative environmental impacts via excess nitrogen excretion. Reducing dietary protein in poultry diets can help to mitigate some of these negative effects. In poultry diets,...

INTRODUCTION Coccidiosis remains one of the most significant diseases affecting poultry production globally. It is well-recognized that infection with Eimeria parasites occurs in every location where chickens are raised and these infections influence growth, feed efficiency, mortality and the susceptibility to other diseases. As a result, the economic impact of coccidiosis is likely greater than any other disease affecting poultry production, with a recent global estimate of...

Glucagon-like peptide (GLP) is one of the major intestinal hormones and has two subtypes, GLP-1 and GLP-2. GLP-1 is a 36-amino acid peptide released from intestinal L cells in response to ingested nutrients [1]. In the gut, this peptide hormone performs a variety of physiological and biological roles. Some of these functions include enhancing glucose-dependent insulin release, inhibiting glucagon secretion, increasing pancreatic β cell growth [10, 27], decreasing food intake [1],...

One of the greatest challenges to production facing poultry farmers in India is heat stress and the strain that it causes to the bird. Climatic conditions in India are such there is intense radiant energy for an extended period of time. Poultry create a large quantity of metabolic heat and accumulate additional heat from radiant energy. Heat production and accumulation, coupled with compromised cooling capability because of environmental conditions, causes heat load in the bird to increase...
