In-vitro and In-vivo Evaluation of the Anthelmintic Efficacies of Chrysophyllum cainito and Psidium guajava Bark Extracts Against Ascaridia galli of Chicken (Gallus gallus domesticus) |Chapter 6| Research Perspective on Biological Science Vol. 3

Herbal medications still hold a significant place in local communities, particularly among small farm holders, mostly in resource-constrained areas. While technological advancements in animal medication rise and dominate these days, some associated issues, such as too much reliance on pharmaceuticals, may incubate unwanted drawbacks, including drug resistance and residuals in animal by-products. Thus, holistic treatment approaches to animals persist and are maintained, comprising the traditional uses of herbal plants, which have remained sustainable through the years.  This research aspires to bridge the gap between folklore and scientifically proven treatments, such as those synthetically prepared dewormers for commercialisation. This study assessed, via in vitro and in vivo assays, the anthelmintic activity of Chrysophyllum cainito and Psidium guajava, which are among the collection of documented flora in the Philippines utilised by locals in their ethno-veterinary medicine practices. In vitro anthelmintic evaluation displayed time-dependent and concentration-dependent efficacies. Chrysophyllum cainito bark ethanolic extract (60mg/ml) recorded 94.65% egg-killing activity, whereas Psidium guajava bark ethanolic extract was 92.64% effective at 30mg/ml and 96.28% effective at 60mg/ml. The worm-killing activity of the former at 60mg/kg yielded 88.88%, while the latter elicited 88.88% and 94.44% mortalities to worms at 30mg/ml and 60mg/ml, respectively. Probit analysis on the lethal concentration (LC50) against eggs and worms was conducted at different magnitudes for both plants, inferring substantial anthelmintic action. The in vivo evaluation through faecal egg count reduction (FECR) rate indicates that both plants can effectively inhibit and kill gastrointestinal nematodes, as substantiated by the significant ovicidal and wormicidal activities. The generated findings herein can contribute to the broader field of sustainable animal health practices and advocacies as we rally against current pressing issues relating to food safety and public health.
