1. Introduction The population of the world is growing at exponential rates and, according to United Nation’s Revision of World Population Prospects https://esa.un.org/unpd/wpp/), it is projected to reach a number of over 9.7 billion by 2050. This population growth poses issues that may affect the sustainability of demographic, social and economic systems. More specifically, one of the main challenges consists of finding a way to feed all these people and agriculture,...

1. Introduction Ochratoxin A (OTA) is a secondary metabolite of certain species of the Aspergillus and Penicillium genus [1]. The chemical structure of OTA consists of weak organic acids with a dihydroisocumarin moiety joined by a peptide bond to 1-phenylalanine [2]. There are three ochratoxin forms, designated as A, B and C, which have slight structural differences; however, ochratoxin A (OTA) is chlorinated and is the most toxic one [3]. OTA contamination in Europe in the year...

Ingredients are the basis of all animal feed. In times where alternative ingredients receive more and more attention, we should not forget to ask ourselves how ingredient properties affect the transition into actual feed. It is time to unravel the black box that is...

Introduction
The issue of gut health in relation to gut bacterial became more evident with the ban of antibiotic growth promoters (AGPs) in animal/poultry nutrition. This ban became preeminent with the development of resistant bacteria strain getting into the food chain. This will ultimately result in bacteria related health issues for consumers of poultry product. In the poultry industry, gut health is not just an interaction between gut bacteria; nutrients provided...

Deoxynivalenol (DON) is one of the most common trichothecenes mycotoxins, and is a natural occurrence mycotoxin produced by Fusarium graminearum . DON also is known as vomitoxin due to its strong emetic effects after consumption and causes animals’ vomit. DON occurrence in food and feed represents more than 90% of the total number of samples, and it is a potential marker of the occurrence of other mycotoxins.
The occurrence of mycotoxins originates from before and after...

USPOULTRY and the USPOULTRY Foundation announce the completion of a funded research project at Texas A&M University in College Station, Texas, in which the role dietary calcium plays in necrotic enteritis (NE) development and pathogenesis was examined. The research was made possible in part by an endowing Foundation gift from the Sanderson Farms and is part of the Association’s comprehensive research program encompassing all phases of poultry and egg production and processing. A...

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...

INTRODUCTION Newcastle disease virus (NDV) is Avian avulavirus type-1 that belongs to the genus Avulavirus of the family Paramyxoviridae (Swayne and Glisson, 2013). Newcastle disease virus isolates vary in their pathogenicity to chickens and may include at least 3 pathotypes; lento-genic (low virulence), mesogenic (moderate virulence), and velogenic (high virulence). Velogenic NDV remain a major threat to the poultry industry because of high mortality and reduced egg production...

Mycotoxins are a group of structurally diverse secondary metabolites of fungi that occur as contaminants of grains worldwide. Aspergillus, Alternaria, Claviceps, Fusarium and Penicillium species of fungi are ubiquitous in nature and under ideal conditions often infect economically important crops during storage, shipment and processing. Many secondary metabolites produced by these fungi can cause serious health problems in poultry and their presence in agricultural commodities may result in...

In some companies, fertility and hatchability start to decrease during the last weeks of production, for example after 50 weeks, at the same time there is a loss of feathers in the back or there is an overweight of the egg. How can we improve fertility and hatchability in the last phase of production of broiler breeders? To improve fertility and hatchability we must evaluate three important points: (a) management of the roosters, (b) hen feather cover and (c) egg size. ...

Methionine belongs to the twenty amino acid making up proteins. It is an essential sulfur-containing amino acid. As essential aminoacid, It cannot be synthesized by the animal and its requirement should be supplied trough the feed. It is one of the first limiting amino...

1. Introduction In hot climates, the growth of broilers is usually slow, as high temperature adversely affects feed intake, and high-protein diets, used to sustain animal growth, may impair broiler tolerance to heat stress due to the high heat increment induced by protein metabolism [1,2]. Decreasing dietary protein levels of broiler diets could be a good strategy, but the amino acid requirements for broiler chicks must be satisfied by supplementing synthetic amino acids to the...
