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.

When it comes to setting minimum ventilation fan runtimes during cold weather it is important to keep in mind that one of the primary objectives of minimum ventilation is to manage house moisture levels. Too much fan runtime will not only result in excessive moisture removal from a house, leading to dry, dusty conditions which can lead to bird respiratory issues, but it will also result in high heating costs. Conversely, if the minimum ventilation fans are not operated enough, too little...

Introduction Heat stress is one of the major problems of poultry in heat areas of the world including Iran, especially in summer, leading to reduced performance, the production, feed intake, growth rates and effective use of the feed (Sahin ., 2009). In general, birds have a thermal comfort zone, which ranges between 18 to 22 ° C and no problem for the physiological regulation of body temperature in this range will. Birds lack sweat glands, increase in...

Thermal stress happens when the animal leaves its thermal comfort zone, it means neither too cold nor too hot, let's say it feels good. In both of the cases, the stress due to heat and cold, the problem itself is not the temperature alone, but its relation to relative humidity level. The...

The house has been preheated for 36 hours to 92°F. The chicks will be arriving in a few hours and the controller’s six temperature sensors (positioned one foot above the floor) indicate the air temperature is between 91 and 92°F (Figure 2). A thermal image indicates the floor temperature is between 87 and 102°F...

Introduction Global consumers have ongoing concerns about the effects of animal production systems on animal welfare and their effects on quality attributes of food products from intensive production systems [1]. Due to consumer concerns, research on animal welfare has been strengthened [2]. Welfare has become one of the most important and essential topics for modern animal production because animals are sentient beings capable of suffering and experiencing emotional states [3,4]....

As discussed in  Part 1 of "Balancing Poultry House Moisture Levels,"  one of the primary objectives of a minimum ventilation system during cold weather is to manage house moisture levels. If we get rid of too much moisture, a house will become dry and dusty, which can lead to respiratory issues. Conversely, if we don't get rid of enough moisture,...
