Poultry welfare
Proper animal welfare involves providing the proper housing, management, nutrition, disease prevention and treatment, responsible care, humane handling and, when necessary, humane euthanasia. These factors allow for the most optimal and humane growing environment. The concept of animal welfare includes three elements: the bird’s normal biological functioning, its emotional state and its ability to express its natural behaviors. Improving animal welfare can be accomplished through offerings like poultry feed enrichment, which can reduce stress, thereby increasing performance, productivity and profitability. Animal welfare is currently a major requirement for intensive poultry production. Beak trimming, stocking density, free access to feed, heat stress, and air pollutants became important issues, which are regulated in several countries. Animal welfare is observed by watching how birds naturally behave and even by looking at mortality stemming from aggressive behaviors.

1. Introduction One of the main goals of free-range egg production is to optimise laying performance and egg quality while supporting hen health and welfare. However, opportunities provided in the free-range system allow for the expression of a variety of behaviours, interactions and physical experiences (e.g., being exposed to uncontrolled environmental conditions) which may impact hen health, welfare, and survival [1–3]. For example, free-range flocks are frequently...

I. INTRODUCTION The global supply of poultry products will need to double by 2050 if we are to meet the aspiration of all people to be food secure. We will need to produce more poultry meat in the face of changing consumer perceptions and constrained resources. Consumers expect this to be achieved in a sustainable manner. The industry has the skills to achieve this. Genotypes continue to improve; production methods and business models are evolving; and we have enhanced our...

When humans domesticate and breed an animal, they tend to select for a very specific trait. In laying hens, artificial selection for high egg production has led to hens that can produce 320 eggs a year. But could artificial selection have unintentionally altered hen brain morphology?
In a new study, published in the July issue of Poultry...

INTRODUCTION Despite superior color vision, hue discrimination, and motion detection, broiler chickens are typically kept in lighting conditions deemed suitable for humans. Environments tailored to poultry vision could lead to improvements in bird health, welfare, and performance by supporting the development of normal vision and in male broilers (Edwards, 2003). UVB exposure also improved bone mineral density, egg production, and levels of vitamin...

Gangrenous dermatitis (GD) is a serious bacterial disease affecting poultry. It generally is fatal, often within 24 hours. It sometimes seems to appear almost out of nowhere because suddenly you will have healthy birds and dead birds, but not many birds in between. While GD has been reported in commercial layers, turkeys, and broiler breeders, it usually occurs in fast-growing broilers between 4 and 8 weeks of age .
In recent years, there has been an increase of...

The occurrence of pasty vent is usually observed after 3 days of age when chicks are mainly depending on their feed rather than their yolk sac. Some chicken flocks present pasty vent more often than others, being their frequency variable and hard to track. How can it be prevented or treated? Could this characteristic damage the growth or feed conversion ratio at the market age? The pasty vents are produced because the cecal dropping has a sticky consistence and thereby not be released out...

Maintaining bird comfort during the hot, humid summer is critical for optimum weight gain, feed conversion, and livability. In most situations, modern-day poultry houses are equipped with tunnel ventilation systems with large exhaust fans at one end and evaporative cooling pads at the opposite end. Evaporative pads are chosen mainly for their high efficiency, while foggers (low-pressure misting systems) may be installed as a supplement to cool cell systems. Unfortunately, however,...

Researchers from Spain and the Netherlands performed a study to determine if adding a mineral and vitamin mix (AHS and Vitamin C) would have an effect on broiler performance in heat-stressed conditions.
1,824 one-day-old birds were randomly allocated to 48 identical pens of 38 birds each. All birds were equally fed a 3-phase feeding program. There was no variation in feed throughout this study.
The control group(s) were...

1. Introduction Heat stress (HS) has undesired effects on the growth performance [1,2] and meat quality [3] of broiler chickens. During HS, chickens seek to dissipate unwanted and excess body heat by increasing panting, resulting in alteration of blood acid/base status, which in turn can give rise to respiratory alkalosis [4] and disruptions in muscle membrane integrity [3]. Additionally, the work required to maintain body temperature consumes diverts energy from metabolic...
