Performance of two egg type chicken farms maintained different bio-security levels

This study was aimed to determine the productive and economic performances of two different genotype egg producing chicken farms carried out with good, fair and poor bio-secured intervention in the south western region of Bangladesh. The world class Hisex White and Hisex Brown layer strainwas used as egg type chicken. According to obtain marks each of one hundred (total two hundred) surveyed farms were divided into good (≥ 80%), fair (61-79%) and poor (≤ 60%) bio-secured categories. Highest numbers of Hisex White (41%) farms but lowest numbers of Hisex Brown (29%) farms were reared under good biosecured condition in the study area. Under good bio-secured level Hisex White and Brown was taken highest amount of feed and produced highest number of eggs. The average egg weight and egg mass of both Hisex White and Brown was not differed significantly (P>0.05) under good, fair and poor bio-secured farms respectively. Under good bio-secured farms FCR value was better than fair and poor farms respectively. Highest percentage of survivability occurs in good and lowest in poor bio-secured condition, both white and brown layer strain. The BCR of Hisex White was found highest (1.13) under good but similar (1.12) under fair and poor bio-secured farms and did not differed significantly (P<0.01). However, the BCR of Hisex Brown was found highest value (1.17) under different bio-security level. This result revealed that the Hisex Brown was less biosecurity sensitive and highly profitable than that of Hisex White farms.
