Comparison of the Keratinase Gene Sequences of Fast, Slow and Intermediate Feather Degrading Strains of Bacillus licheniformis
Abstract: Feathers are composed of beta keratin which is an insoluble protein resistant to degradation. Bacillus licheniformis has a gene that codes for a keratinase enzyme that hydrolyzes feathers. The DNA sequences of the genes coding for keratinase enzymes of various strains of B. licheniformis were compared. Some strains of the bacteria hydrolyze feathers rapidly, some slowly, and some at an intermediate rate. The mature keratinase enzyme is composed of 274 …

Chicken Feather Degradation Using Thermus aquaticus YT-1 and Application of Keratinolytic Protease Produced
Abstract: ABSTRACTAim of the study undertaken was to develop a process to manage chicken feather waste, without use of potential infectious microorganism. Biodegradation of chicken feather mediated by production of keratinolytic protease involving use of non- pathogenic thermophile Thermus aquaticus was investigated. The structural complexity of native chicken feather acts as inducer to increase protease production as compared to feather meal. The keratinolytic protease produced demonstrated more than 50 % stability …

Development of Starch/Keratin/Chitosan Composite Material as a Substitute for Polystyrene in Food Packaging
Abstract: The increase in awareness of the environmental impact of non-biodegradable waste from food packaging, has seen manufacturers push towards initiating production of eco-friendly packaging materials. This research serves as a step forward in the direction of going green, through the development of a composite material from natural, biodegradable polymers, for use in production of packaging material for fast foods. The composite was prepared from starch and chitosan with chicken feather …

Phase-Specific Nutrient Requirements in Broilers: Implications for Behavior, Gut Health, Performance, Meat Quality, Welfare, and Economics
Abstract: The broiler industry plays an inevitable role in global food security, requiring optimal formulation strategies tailored to each growth phase, starter, grower, and finisher for sustainable production. This review explores phase-specific nutrient requirements and their implications for broiler performance, meat quality, welfare, and economics. During the starter phase (1–10 days), nutrition focuses on immune development, gut health, and skeletal growth, with high protein and low energy needs. In the grower …

Rethinking Stocking Density in Broilers: Assessments of Physiological, Behavioral, and Environmental Impacts
Abstract: High stocking density in broiler production is a common practice aimed at maximizing space utilization and economic returns. However, it poses significant challenges to the performance, health, and welfare of the birds. This study explores the multifaceted impacts of elevated stocking density on broiler chickens, highlighting the physiological, behavioral, and environmental factors that deteriorate their overall well-being. Increased stocking density is associated with reduced growth rates, poor feed conversion efficiency, …

Utilization of Different Fiber Feedstuffs in Poultry
Abstract: The difficulty of using high fiber raw materials and ways to improve their nutrient availability is always a hot topic. However, fiber is functionally important for poultry performance, health, and welfare. Although some fiber is indigestible, it plays an important role in the digestive system. It influences gizzard function as well as digesta passage rate. The latest researches precisely recommend 3–4% crude fiber for poultry for a greater period while …

Therapeutic Management of Cutaneous form of Pigeon Pox with Turmeric Paste
Abstract: Initial study has been done to examine the therapeutic management of cutaneous form of pigeon pox with turmeric paste. Avian pox is one of the most common infectious and contagious bird diseases. Pigeon pox is observed during humid summer and winter weather. Avian pox occurs in two forms in birds including cutaneous and diphtheritic forms. A flock of 30 pigeons were kept for the research purpose in a loft in …
