Background and Aim: Gastrointestinal parasites (GIPs) pose a major health challenge for cattle in Indonesia. GIP infections affect the production and reproductive performance of cattle, resulting in economic losses. However, the prevalence and distribution of infections have not been comprehensively profiled at the national level. This study aimed to estimate the prevalence of GIP infections in cattle in Indonesia. Materials and Methods: Overall, 667 articles were identified from six databases in English and Bahasa Indonesia. After removing duplicates and screening titles and abstracts based on the inclusion criteria (i.e., GIP prevalence in cattle in Indonesia), 67 articles were included in the data review. Data were pooled using a random-effects model in STATA software. Heterogeneity was tested using Cochran’s Q-value and I2 statistics, whereas publication bias was assessed using Egger’s regression test. Results: The overall pooled prevalence of GIP in Indonesia was 46% (95% confidence interval 37%–55%), with a total population of 17,278 cattle screened. The I2 value was 99.59%, Cochran’s Q-value was 15,957.25, and p = 0.001. The results of the regional meta-analysis based on the provinces in the three zones of Indonesia showed estimated prevalence rates of 54.0%, 52.7%, and 53.7% in Western, Central, and Eastern Indonesia, respectively. The parasite with the highest prevalence was Eimeria spp. (37.7%), followed by nematodes (34.4%) and trematodes (Fasciola spp., 21.4%). Conclusion: The findings reveal a high prevalence of GIPs in cattle across Indonesia, with significant variability across regions and parasite types. Eimeria spp., nematodes, and trematodes represent the most prevalent infections and underscore the urgent need for region-specific control strategies, including improved livestock management practices, routine screening, and integrated parasitic control programs.

Background and Aim: Seeds from Carica pubescens were observed to be abundant as waste. This waste contains active plant compounds whose utilization has not been studied in the livestock sector. This study was conducted to evaluate the potential of an aqueous seed extract of Carica pubescens (ASE) as an anthelmintic agent during rumen fermentation and methane reduction. Materials and Methods: Aqueous seed extract of Carica pubescens was prepared from C. pubescens cultivated in Wonosobo, Indonesia. Phytochemical analyses were performed to quantify the secondary metabolite content of ASE. In vitro adult worm mortality tests, scanning electron microscopy, and gas production tests were conducted to evaluate rumen characteristics, methane reduction, and the potential of ASE as an anthelmintic against Haemonchus contortus. Adult worms and ruminal fluid were collected from Indonesian thin-tailed sheep. Two-way analysis of variance followed by Tukey’s test was performed using the Statistical Package for the Social Sciences® 21.0 software to detect significant differences. Results: In vitro study results showed that 1–5% ASE inhibited H. contortus after the 1st h of incubation, and 5% ASE suppressed 100% of adult H. contortus worms in the 5th h. Scanning electron microscopy analysis of ASE-treated worms ASE revealed damaged cuticle structures. ASE had no significant effect on pH, NH3, volatile fatty acid, acetate, propionate, butyrate, acetate: propionate, or microbial protein in rumen fluid (p > 0.05). The in vitro feed fermentation results showed that ASE significantly affected methane reduction. Conclusion: The inclusion of up to 5% ASE in sheep diets may serve as a potential alternative anthelmintic against H. contortus as well as a methane reduction agent, without deleterious effects on rumen fermentation.

Aim: This study was conducted to determine the anthelmintic activity of aqueous and ethanol extracts of Paraserianthes falcataria bark against Haemonchus contortus. Materials and Methods: Ethanol extract of bark (E.E.B.) waste and aqueous extract of bark (A.E.B.) waste of P. falcataria (at concentrations 0, 0.2, 0.4, 0.8, 1, 2.5, and 5%) and albendazole (2 mg/ml) as the positive control were placed in separate Petri dishes (50 mm). Twenty H. contortus worms were placed in Petri dishes and incubated at 37°C for 0.5, 1, 2, 3, 4, 5, 6, and 12 h. Mortality of each worm was ensured by pressing the body of the worm with a pair of tweezers and keeping it in lukewarm water for 5 min before declaring it dead. Mortality is defined as amount of death individuals and time of mortality of each worm was recorded. The parasites were then observed using scanning electron microscopy (SEM) at an accelerating voltage of 15 Kv. Statistical analysis was performed using SPSS 21.0 software, two-way ANOVA followed by Tukey's test to detect significant differences (p

Aim: This study was conducted to determine the prevalence of gastrointestinal (GI) worms in Wonosobo and thin-tailed sheep from the slope of Mount Sumbing. Materials and Methods: Fecal samples (n=305) were collected directly from the rectum of Wonosobo and thin-tailed sheep during the dry and rainy seasons in Wonosobo Regency, Central Java Province, Indonesia. The presence of GI helminth eggs in the fecal samples was assessed using the modified McMaster egg counting technique. The identification of the eggs or oocysts was done on the basis of their morphology and size. Results: The highest prevalence of GI worms was observed in male thin-tailed sheep (76.47%) during the rainy season, whereas the lowest prevalence was observed in female Wonosobo sheep (47.36%) during the dry season. The types of GI nematodes observed in these two types of sheep were Haemonchus contortus, Ostertagia spp., Trichostrongylus spp., Bunostomum spp., Trichuris spp., and Moniezia spp. The GI worms with the highest prevalence were of Haemonchus spp. and were observed in male thin-tailed sheep. The prevalences of the two types of sheep assessed at an altitude of 1150 m above sea level were higher than those observed at the altitude of 1586 m. The prevalence of clinical and sub-clinical parasites infestation in Wonosobo and thin-tailed sheep in Kwadungan village was significantly different (p
