Abstract
This study was conducted to: 1) identify the different species of gastrointestinal helminthes present in the experimental chickens; 2) determine the efficacy of decocted tobacco leaves against gastrointestinal helminthes of native chickens; 3) identify the species of gastrointestinal helminthes affected by decocted tobacco leaves; and 4) to determine the most effective dose of decocted tobacco leaves against gastrointestinal helminthes of native chickens.
Seventy-five Philippine native chickens were used in the study. They were randomly distributed into five treatments including the negative and positive controls, replicated three times using Randomized Complete Block Design (RCBD).
The treatments used were as follows: To'-(negative control) no treatment; To+ (positive control) niclosamide-levamisole combination; Ti - 0.5ml decocted tobacco leaves/kg BW; T2- 1ml decocted tobacco leaves/kg BW and T3- 1.5ml decocted tobacco leaves /kg BW.
Prior to treatment, fecal examination was done to determine the pre-treatment EPG count and the species of gastrointestinal helminthes which were further confirmed by adult worm identification at necropsy. They were treated once with decocted tobacco leaves with their corresponding dosages and fecal examinations were done on 1st, 3rd, 7th, 14th and 21st days post-treatment.
The gastrointestinal helminthes identified were as follows: Ascaridia spp., Capillaria spp., Heterakis spp. and Choanotaenia spp. All levels of decocted tobacco leaves (Tl, T2 and T3) were able to reduce the helminth EPG count based on the standard criteria set by Reik and Keith (1957). On post-treatment Ascaridia spp. and
Choanotaenia spp. eggs were eliminated, and the other parasite eggs were still present but all were reduced. The most effective dose was Ti (Iml/kg BW) which was rated highly effective in reducing the helminth EPG count on 21st day post-treatment, with 83.33% efficacy which was comparable to the effect of the commercial anthelmintic.
