Abstract
This study investigated the in vivo effect of Murraya paniculata leaf on gastrointestinal nematodes reduction, growth rates and haematological changes of goats. Four experimental groups (n = 6) of goats naturally acquired gastrointestinal nematodes were control (GI) (untreated), positive control (GII) (treated with albendazole, 6 mg/Kg BW) and GIII and GIV treated with 5 and 10 g/Kg BW of M. paniculata leaves. Fecal samples collections were performed weekly for assessment of fecal egg count. Number of nematode eggs in goat feces (egg per gram; EPG) was determined from week 0 (pre-treatment) to week 8 (post-treatment) by modified McMaster egg counting technique. EPG values of GIV goats were significantly lower than that of the controls and those receiving the albendazole (p<0.05) at week 3. GII goats showed highly effective at EPG reduction in 1-2 weeks after giving albendazole and then the efficiency decreased until the end of the experiment. The effect of M. paniculata leaves on growth rate was studied by examining goat weight on days 0, 30, 60 and 90. GIV group revealed significantly higher weight change than other groups (p<0.05). The feeding of M. paniculata leaves at different levels did not affect on haematological parameters, glucose, total protein, urea, albumin and globulin of goats. It was found that values of the haematological parameters were within the range of the standard values. Compound analysis of M. paniculata leaves revealed that M. paniculata leaves contained higher protein content than grass and the protein content was closed to the meal concentrate. This corresponds to the best growth rates of GIV goats. The results demonstrated that M. paniculata leaves reduce the gastrointestinal nematode eggs of goats efficiently, safely and environment-friendly.

Summary
Goat farming is an interesting source of earnings for goat shepherd in Lopburi province, Thailand. Boonkusol (2016) studied prevalence of gastrointestinal parasites in goats at different age and sex in six districts of Lopburi province and reported that strongyle-type eggs, Trichuris spp. eggs and coccidian oocysts were found with prevalence rates of 67.2%, 4.4% 78.8%, respectively. High infection of gastrointernal parasites were observed in goats at age of 13 year (57.3%) and < 1 year (36.9%). Most of the effects caused by helminth parasitoses were unnoticed due to sub-clinical or chronic character of the diseases (Dawo and Tibo, 2005). Antibiotics use in the diseases control is no longer sustainable because of high levels of antibiotics resistance, high cost and residue problem (Waller, 2006)
