The aim of this study was to determined the prevalence and infection disease degree of worm gastrointestinal on duck in two different geographical territories. The duck feces examination samples were using natif method, sedimentation, and floatation. The result of this examination of lowlands showed that 20% (12/60) ducks checked that infected by two worm species of nematoda, wich ia Ascaridia galli (11,7%), Heterakis sp. (8,3%), with the range of infection degree classified as low infection (0-500 EPG), while the examination results of highlands showed that 44% (33/75) ducks checked infected by two worm species of nematoda, which is Ascaridia galli (17,3%), Heterakis sp. (10,7%) and one species of trematoda, which is Echinostoma sp. (6,7%), with the range infection degree classified low infection (0-500 EPG). it can get both single or mix infection. The analysis result has shown that there was differences between lowlands and highlands on the prevalence and infection disease degree of worm gastrointestinal on duck, was highly significant (p<0,05).

This research aim to attest the potential anthelmintic extract  mango seed gadung  (Mangifera indica L.) against worms Mecistosirrus digitatus in vitro, the study also aims to determine the effect of immersion time, variasis concentration and the relationship between time and treatment. this study used 210 M. digitatus worm extracted regardless of gender worms. treatment that is given was  the concentration  extract  mango seed gadung  was 5%, 7.07%, 10%, 14.14%, 20%, negative control using NaCl physiological  and comparison using levamisole Hidrokloride 0.0025 mL. Observations death worm Mecistocirrus digitatus and observations were made at the 6th hour, 12th hour, 18th hour and 24th hour. The results showed that variations in concentration, soaking time and the relationship between soaking time with the treatment affect mortality Mecistocirrus digitatus worms. Test results of the analysis statitistik using factorial Anova and Duncan's Multiple Range Test showed a significant difference (p<0.01) between the time factor, variations in concentration and relations between time and treatment.

The purpose of this study was to identify the type of gastrointestinal worms egg of Spotted Deer (Axis axis) and Bawean Deer (Axis kuhlii) at Wonorejo Bibit Park and Surabaya Floral Park. The research was conducted in October-December 2017 used total 50 specimen of sample faeces, 40 sample faeces from Surabaya Flora Park and 10 sample faeces from Wonorejo Bibit Park, the samples analyzed at the Department of Parasitology Veterinary, Faculty of Veterinary Medicine, Airlangga University. The results showed that the degree of helmint gastrointestinal in Bawean Deer and Spoted Deer at Wonorejo Bibit Park showed 0% while at the Surabaya Flora Park is 15%. The type of worm found were Trematoda class it was Fasciola sp. The resuls of the analysis used Chi-Square test and showed no significantly differences degree of gastrointestinal helminth infection (p>0.05) .

The purpose of this research is to determine the kind of nematodes and to determine the prevalence result. Thirtysix samples of omasum and abomasum were collected from RPH Pegirian from September-November 2017 then using gastrointestinal surgery to get fresh adult worm, afterwards using Semichen-Acetic Carmine stainning method to makes the object easy to microscopic identify. The result showed that species was found Haemonchus contortus, as an identify result show that adult worm has a character on a anterior part called cervical papilae, female  worm has a barber’s pole on body also posterior part has a vulva flap, posterior part of male worm has a bursa copulatrix, spicula, gubernaculum and dorsal rays looks like Y shape. Seventeen positive samples and the prevalence rate was 47,2%, 273 adult worms and female worms 215 (78,75%) and the male worms 58 (21,25%). Chi-Square statistical test (P <0.05) showed that 13 positive samples of kambing kacang (65%) were higher infected Haemonchosis infection than 4 potitive samples of PE (25%).

This research was conducted to determine the anthelmintics effect of peel a pomegranate fruit extract etanol against Ascaridia galli worm in vitro. In this research, using 240 samples of A. galli with length 7-11cm without differentiating sex. The concentration of peel a pomegranate fruit extract etanol for immersing the Ascaridia galli were 10 mg/ml, 20 mg/ml, 40 mg/ml, and 80 mg/ml. Negative control was used PBS. Positif control was used piperazin citrate 10 mg/ml. Observation death A. galli worm and analysis of the data at the 6 hour, 12 hour, 18 hour, 24 hour, 30 hour and 36 hour using ANOVA test and Duncan Range Test. ANOVA result showed significant differences between treatments (p<0,05). Duncan Range Test result showed peel a pomegranate extract etanol 40 mg/ml had anthelmintics effects the 36 hour which comparable with piperazin citrate 10 mg/ml.
