Abstract
Influence of Housing Floor on Air Quality, Growth Traits, and Immunity in Broiler Chicken Farms
Highlights
The poultry industry as one of the main sources of animal protein and white meat in Egypt and worldwide faced a lot of obstacles, including the choice of the perfect housing floor system
The five rooms were supplied with different housing floors; the 1st room was supplied with wood shaving litter, the 2nd was supplied with rice husks litter, the 3rd room was supplied with wheat straw litter, the 4th room was supplied with plastic slats, and the 5th room was supplied with horizontal cages
Growth Traits Bodyweight gains (WG) and performance indices (PI), as recorded in Table 2 revealed highly significant increases (P < 0.01) in broilers raised on the battery and slatted floor with no significant differences between the battery and slatted floor systems in WG values
Summary
The poultry industry as one of the main sources of animal protein and white meat in Egypt and worldwide faced a lot of obstacles, including the choice of the perfect housing floor system. Over many years raising broiler chickens worldwide and in Egypt was depending on the deep litter system using a variety of litter types (Aviagen, 2016). US Publishers litter system in raising broilers is dependent on many management factors to control litter moisture percent and pH as well as to control ammonia levels inside poultry farms (De Jong and Gunnink, 2014). If these managemental factors were not optimized and maintained, diseases risk like respiratory diseases and dermatitis can be increased (Sohirat Torfy et al, 2017; Petek et al, 2014). The degree of dryness of the bedding material in deep litter systems depends on many factors like stocking density, watering system, type of bedding material, indoor temperature, relative humidity, and degree of thermal insulation (Petek et al, 2015; Jacob et al, 2016)
