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.
Introduction Poultry, due to its genetic, nutritional and managemental upgradation have become a source for quick productivity. But, skyrocketing conventional ingredients, fluctuating managemental conditions, and other quality parameters of rearing birds, farmer...

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...

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 Controlling production costs and animal welfare are important factors for breeders. Feed accounts for 50 to 70% of the production cost in poultry production (van Horne, 2018). The feed conversion ratio (FCR), which is the ratio of feed consumption to meat or egg production, is an important criterion for the profitability of these farms. It is also an indicator of the environmental impact of production. For example, the reduction of 10% in FCR results in a reduction...

INTRODUCTION Broilers and turkeys are traditionally kept under monotonous environmental conditions, which compromise bird welfare due to inactivity, restriction of the behavioural repertoire and various health hazards. Recent development of welfare labels request enrichment devices in order to stimulate the expression of a wide spectrum of behaviours and to improve the physical and psychic conditions of the birds. Consequently there has been a rapid development of studies...

In 2020, the poultry industry had a combined value of over $35.5 billion in the United States. Of that, $21.7 billion came from broiler chicken production (USDA-NASS, 2021). Over 9.22 billion broiler chickens were raised and brought to market though the year, making it the largest and most valuable sector of U.S. poultry production. With such...

Sickness behavior is an animal’s adaptive response to disease which aids in their recovery. When an animal is infected by a pathogen, an immune response involving immune cell and immune molecule activity is stimulated and sickness behavior results. Sick chickens are difficult to identify because they rarely show signs of illness before it...

In most regions, summer is around the corner and poultry farmers need to prepare the birds to combat the heat and hence stay productive. Adding a powerful yeast postbiotic can help broilers absorb nutrients more readily and keep cool. When the chicken is healthy and performing at its best, the bird is in a state of physiological equilibrium (homeostasis). When the animal is exposed to stressors, coming from external sources (such as heat stress) or internal sources (such as metabolic...

Bird performs well within a certain range of environmental temperatures. As the temperature gets higher than the range, the bird falls on stress generally called heat stress. Heat stress is the most significant stressors influencing poultry productivity and causing considerable economic losses in the poultry industry. This induces several negative effects on physiological response of bird. Reducing feed consumption, body weight gain, feed efficiency, egg production and immune response are of...

INTRODUCTION Although rearing the meat poultry in cage systems has recently attracted a lot of attention, however, some of the meat poultry stocks particularly broiler chicken still grow up on the floor of the poultry houses with a substrate known as litter material as poultry bedding. The recent trend in poultry industry has increased the demand for litter materials. Litter serves a number of important functions, such as absorbing moisture of excreta, reducing contact between...

Though broilers often appear to be evenly distributed throughout a house, more times than not our eyes are deceiving us. Figures 1 and 2 are of the tunnel fan and tunnel inlet ends of a 50' X 600' broiler house with 20-day-old birds. At first glance bird density appears fairly uniform but when examined closely, it becomes apparent that there are more birds near the tunnel doors (far right of Figure 2) than in any other area of the house. The question are, of course, is this...
