EGG white lysozyme concentrations in white plymouth rock hens treated with the immunomodulator helpankar

Egg white lysozyme concentrations were assayed in White Plymouth Rock hens, treated twice with the polybacterialimmunomodulator HELPANKAR. The experimental flock exhibited higher levels of egg white lysozyme compared to untreated birds throughout the observation period from 24 to 64 weeks of age. Maximumvalueswereattainedby42–44 weeks of age: 10325.64±158.43 mg/L and 10475.67±133.55 mg/L respectively. The lysozyme values in control flock were comparable, with highest values from 3448.15±212.82 mg/L to 3842.25±185.28 mg/L corresponding to 33.4% to 36.7% of those in the experimental flock. The twofold treatment of experimental breeder flock with the immunomodulator Helpankar resulted in 2-3 times higher lysozyme concentrations in breeder eggs.
