Sesbania (Sesbania grandiflora) supplementation for growth performance and gastrointestinal parasites control in goats
Abstract:
There were six experiments conducted in this study. Experiment 1, prevalence of gastrointestinal parasites infection in goats, was studied in Bangkok and vicinity in Central Thailand. Assessment on infection type and risk factors were studied and comparison was made with prevalence in Malaysia. Infection in Bangkok and vicinity was recorded at 68.65% on individual level. Two risk factors significantly influenced the infection in Bangkok; sex and type of goat reared in farm. Experiment 2, tannin as a responsible anthelmintic property in experimental plant, Sesbania grandiflora leaves, was measured by quantification method. Tannins were measured at 1.0842% and categorized as medium level. Experiment 3, in vitro anthelmintic efficacy test, was conducted on three different life cycle stages of helminth parasites; egg, infective larvae and adult for three selected important species in goats. In vitro anthelmintic tests showed significant inhibition effects on egg hatching and motility for larval and adult stage of helminth parasites (P<0.05). Subsequently, preliminary trial of goats preference towards fresh and dried leaves of S. grandiflora was conducted for four weeks in Experiment 4. Utilization of S. grandiflora showed significant anthelmintic effect (P<0.05) but no statistically different observed between fresh and dried leaves. Thus, in term of practical management, dried leaves were chosen to be used for supplementation form in Experiment 5. Supplementation feeding with dried leaves of S. grandiflora was conducted for four weeks with designated feeding regime. The last experiment, treatment with aqueous oral drenching of S. grandiflora, was conducted in goats for 12 weeks in Experiment 6. Supplementation feeding with dried leaves of S. grandiflora and two frequencies of treatment with aqueous oral drenching of S. grandiflora; daily and weekly displayed a positive effect on growth performance and parasite egg count reduction. No side effects were recorded as indicated by negative observation on toxicological symptoms. In conclusion, S. grandiflora was scientifically proven to have the ability to be use as a growth performance supplementation and natural anthelmintic for goats.
