Comparison of a 3ABC Elisa and the Liquid-Phase Blocking Elisa of Foot-and-Mouth Disease in an Area of Endemicity

Abstract

A study was conducted to determine the parameters of productivity of local chickens raised in semi-intensive farming. This study involved 64 chickens divided into two groups of 32 animals. One group was raised in semi-intensive farming (test group) and the other group (control) was raised in free-range farming. The hens brood their eggs themselves and raised their chicks until weaning. After 365 days of study, it was noted that the number of eggs laid per hen was 87.69 ± 2.41 for the chickens in the test group, and 41.41 ± 3.00 eggs for free-range chickens (controls), the number of reproductive cycles was respectively 5.82 ± 0.14 for the test group and 3.20 ± 0.21 for control chickens. Hens under semi-intensive conditions produced on average 64.73 ± 1, 38 chicks for an average of 74.14 ± 1.36 eggs hatched, while controls totaled 28.95 ± 2.65 for an average of 40.86 ± 3.03 hatched eggs, and the average number of weaned chicks under semi-intensive conditions was 56.50 ± 3.53 heads against 16.32 ± 3.03 weaned chicks for free-range hens. The semi-intensive farming system improved the productivity of local hens.
