Abstract

Leptospirosis is a zoonotic disease caused by Leptospira bacteria. The disease was spreadout arround the world, especially in the tropical and subtropical regions included Indonesia. The International Leptospirosis Society has established Indonesia is the country with high incidence of leptospirosis. Daerah Istimewa Yogyakarta is one of the regions in Indonesia with endemic of leptospirosis. Leptospirosis infection in humans can occur through direct or indirect contact with the urine of infected animals. Cattle is one of the source of transmission leptospirosis to human and other animals. The purpose of this study was to determine the prevalence rate of leptospirosis and identify serovar caused of leptospirosis in cattle at Giwangan’s abattoir Yogyakarta. Blood collection taken from ten heads of cattle via jugular vein and the serum was separated for leptospirosis examination by Microscopic Aglutination Test (MAT) which taken placed at Balai Besar Penelitian dan Pengembangan Vektor dan Reservoir Penyakit (B2P2VRP), Salatiga. Microscopic Aglutination Test carried out on various Leptospira serovar, namely: Bangkinang, Canicola, Pyrogenes, Robinsoni, Hardjo, Djasiman, Grippotyphosa, Hebdomadis, Icterohaemorragie, Pomona, Bataviae, Rama, Mini, Sarmin and Manhao. The prevalence rate detemine by compared between the number of MAT positive and samples examined. Positive agglutination indicated the serovar types that caused leptospirosis in cattle. The results showed that two samples were positive against antigen serovar Grippotyphosa (1/2), Hebdomadis (2/2) dan Mini (1/2). It can be concluded that the prevalence rate of leptospirosis in cattle at Giwangan’s abattoir Yogyakarta were 20%. The cause of leptospirosis in cattle at Giwangan’s abattoir Yogyakarta namely Leptospira interrogans serovar Grippotyphosa, Hebdomadis and Leptospira borgpetersenii serovar Mini.

Abstract

Research was carried out to examine the effect of giving Citrus aurantifolia as an acidifier on growth in broiler. The research uses an experimental model with the application of a Completely Randomized Design (RCD). The treatments tested consisted of four treatments which were differentiated based on the level of use of Citrus aurantifolia in drinking water, namely without Citrus aurantifolia (T0), 25 ml/975 ml drinking water (T1), 50 ml/950 ml drinking water (T2), and 75 ml/925 ml drinking water (T3). Each treatment was repeated four times so that there were 16 experimental units, each experimental unit consisted of 5 broiler chickens so that a total of 80 chickens were used. The variables observed were body weight gain, feed consumption and feed conversion. Data analysis used analysis of variance (Anova) and Duncan’s multiple range test. The results showed that the increase in body weight for T0, T1, T2 and T3 was 103,13±3,72, 107,21±5,08, 112,31±073, 120,94±2,13 g/head. Feed consumption was 162,65±1.80, 165,82±0.49, 168,30 ±0.71, 170,36±0.23 g/head. Feed conversion was 1,58±0,05, 1,55±0,07, 1,50±0,01, 1,41±0,02 g/head. The result statistical analysis (Anova) showed that the treatment had a very significant effect (P>0,05) on body weigth gain, feed consumption and feed conversion of broiler. it was concluded that the addition of Citrus aurantifolia as an acidifier in drinking water can have a positive effect on body weight gain, feed consumption and feed conversion in broiler.

Abstract

The aimed of this research is to determine the prevalence of Haemonchus. contortus and the associated risk factors. In this study, 739 fecal samples from Lakor goats were randomly collected from five villages in Lakor District, Southwest Maluku. All samples were taken from goats showing clinical symptoms such as emaciation, diarrhea, dull fur, and inactive. Fecal samples were examined using the native method. Data presentation was analysed using the Chi-Square (X2) and Spearman's test statistical analysis methods. The prevalence of H. contortus in Lakor goats in the Lakor sub-District was 81.60% with the highest prevalence was found in Yamluli Village and Lolotuara Village. The correlation coefficient was 0.838** - 0.931** (P0.01). These data indicated that there is a close relationship between the incidence of H. contortus worm infection in lakor goats and the risk factors in the form of gender, age of the goat and body score condition (BCS) as indicated by the high correlation values.
