Water is a critical nutrient that receives little attention until a problem arises. Not only should producers make an effort to provide water in adequate quantity, they should also know what is in the water that will be flowing through the water lines to be used in evaporative cooling systems and consumed by the birds. Water is needed for bird consumption, reducing air temperature (including evaporative cooling pad and fogging systems) and facility sanitation. Broilers consume approximately 1.6 to 2.0 times as much water as feed on a weight basis. Water is a critical nutrient in bird metabolism and nutrition. From a physiology perspective, water consumed by the bird is used for nutrient transportation, enzymatic and chemical reactions in the body, body temperature regulation and lubrication of joints and organs. There is a strong relationship between feed and water consumption; therefore, water can be used to monitor flock performance.
Drinking behavior in poultry develops within the first couple days of life. When an open water source is provided, birds stick their beak roughly 10 mm into the water, use a scooping motion to collect water in their beak, extend...
1. Introduction Emerging biomarkers hold the potential to revolutionize veterinary medicine by enabling swift disease diagnosis, enhancing animal health monitoring, and optimizing welfare and production efficiency [1]. Nevertheless, the journey from biomarker identification to practical application is often fraught with challenges. Existing diagnostic tools for assessing gut health in poultry suffer from drawbacks, including invasiveness, subjectivity, labor intensiveness, and/or...
A poultry house controller's temperature sensors are, in a sense, its "eyes" enabling it to “observe” what is happening throughout a poultry house so it can accurately determine what equipment it needs to operate to maintain the proper environmental conditions throughout a house. As a result, a...
What is litter? Litter and its management are an essential part of bird management and ensuring bird welfare. This goes for broilers, turkeys, or laying hens kept on litter floors. Litter is a combination of the bedding used within a house combined with the excreta from the birds. Good quality litter provides...
Probiotics are included in the feed and administered continuously during the entire production cycle to maintain intestinal integrity and strengthen the immunity of the bird, thus reducing the need for repeated medication. Alternatively, water-soluble probiotics are often applied to quickly react to upcoming stress situations in the flock – but they can negatively impact the formation of biofilm in the water lines. For this reason, formulations that reduce the formation of biofilms...
The WVEPAH training program is designed for veterinarians and poultry professionals who wish to consolidate and refine their knowledge in areas such as pathology, nutrition, biosecurity, and epidemiology, among others. We are pleased to announce our upcoming course:

Gonzalo Moreno (FENAVI Executive President) comments on the relevance of a sustainability program as a managerial tool, and how to better communicate its impact, in this Engormix interview....
Air is made up of appox. 21% oxygen. Air acts as a big reservoir for oxygen. Oxygen concentration in water is limited by its solubility:
Borewell/Tube well water has NO DISSOLVED OXYGEN?
“Normal underground water concentrations have little or no dissolved oxygen”

INTRODUCTION Campylobacteriosis is among the most frequently reported bacterial foodborne infection in both the European Union (EU) and the United States, with Campylobacter jejuni as the major causative agent. In the last decade, the number of confirmed infections in the EU exceeded 200,000/year. Symptoms of campylobacteriosis include diarrhea, fever and cramps. Death rarely occurs, but complications can increase more than fivefold due to infections with antibiotic-resistant...
The first few days of life are some of the most important in chicks' lives. During this time, chicks start developing and set themselves up for the rest of their lifetime. The husbandry decisions made at this point can impact the birds' growth, development, health and welfare. This newsletter will focus on three important...
1. Introduction Animal welfare is a fundamental component of sustainability, agricultural development and food security. In order for a livestock system to be sustainable, it should be sustainable economically, environmentally and ecologically, and at the same time, it should be accepted ethically and socially [1–3]. Today, a product of animal origin is not considered sustainable unless the social demand for welfare of the production animals is satisfied [1]. Animal...

We know that young geese benefit from warmer drinking water, but what is the optimal water temperature? Poultry scientists take a closer look
A new investigation into goose health suggests providing drinking water that is at least 18? (64.4?) may boost the activity of digestive enzymes, promote intestinal development, increase water consumption, and even increase goose eye temperature. Based on their findings, the...
Dr. Mário Penz (Cargill) discusses the consequences of not managing water properly and the different factors to consider regarding its quality, during this Engormix interview....
INTRODUCTION In practice it is very difficult, if not impossible; to formulate diets with natural feed ingredients that will provide all the amino acids needed by broiler chickens in adequate quantities. The optimal use of liquid and synthetic amino acids in animal diets, therefore, becomes important not only in nutrition and economic aspects, but also in environmental aspects. It is well known that optimal use synthetic amino acid improves amino acid balance and protein...
I Introduction As the single greatest nutrient input into the production of eggs and meat, water quality and quantity deserve careful attention to assure optimal flock performance. Twenty-five years of assisting the poultry industry worldwide with identifying and correcting drinking water challenges provides the foundation of experience and expertise which will be shared in this paper. Birds are fairly tolerant of most contaminants in drinking water. While standards exist for...
Mohammad Afrouziyeh (University of Alberta / Poultry Innovation Partnership) shares his recommendations and insights on water quality, as well as a new tool to control it, during this Engormix interview....
While summer spells fun for most of us, it’s a little different for our poultry animals such as broilers and laying hens. High temperatures cause drops in production, dehydration and heat stress which may lead to more problems like foot pad dermatitis, respiratory symptoms, shell quality problems and even death. So let's take extra care to ensure poultry welfare by providing them with easy access to clean water, shade, and proper ventilation to prevent heat exhaustion. Make sure to monitor...
The issue of antibiotics resistance on animals has raised concerns about meat safety and human health. The banning of antibiotics- growth promoter in animal feed was announced in the EU in 2006. Other countries are starting to follow the regulation to comply with the compulsory withdrawal periods to ensure ‘antibiotics free products. Supplementation in nutrients to enhance the immunity system and lower the risk of the pathogen can help to reach the balance between maintaining animal...
