Proteins consumed by poultry turns into ammonia as a result of microbial activities depending on the pH, temperature, moisture content of the litter, litter type, manure condition, relative humidity and ventilation condition and spreads to the environment as ammonia gas. Ammonia gas, which is one of the problems caused by poultry breeding, is a harmful gas in terms of animal welfare, health of employees and its effects on the environment. In this article, ammonia gas emission in poultry and practices to reduce this emission have been discussed and recommendations have been made.

Peptides with antimicrobial properties as an alternative to antibiotics antibiotic growth promoters in poultry nutrition have been studied in recent years. These peptides, which can be supplemented to diet or water, are effective not only against bacteria but also against fungi, viruses and parasites. In this article, the definition, the structures, the types, the sources of production, the application areas, the microorganisms they act on and the mechanism of action of antimicrobial peptides and information about the studies related to their use in poultry nutrition will be given.
