Optimum Hatching egg size and sexual maturity: Management procedures must be strictly followed through out growing life cycle for quality eggs.
For example – hens grown to have smaller frames will produce smaller eggs that consequently produce smaller and more fragile chicks.
- » These chicks hatched from small eggs normally experience a higher percent rate of mortality.
- » They will grow more slowly and require a longer time to achieve projected body weights.
- » The end result is lost Dollar/pounds/Rupee of poultry meat on a production unit.
Clean Nest Material:
» A gram of contaminated litter can have up to 600,million microorganisms.
» High quality litter material and practicing good litter management and sanitization can significantly reduce percent of dirty eggs and contamination, explosions, and second quality chicks.
» As breeder age increased the percent of eggshell contamination increases due to thinning of egg shells. Thus it is suggested to double the disinfectant dosage in the egg sanitizing spray used on eggs from breeders after after 55 weeks of age.
» Exploders should be removed by 10–12 days of incubation. Exploded eggs in the setter will facilitate dissemination of bacteria and molds and result in contamination to other eggs and to recently hatched chicks in the setter.
