Background and Aim: A local microorganism-based probiotic has been developed as an alternative to using antibiotic growth promoter and its effect on broiler meat quality has been studied, when supplemented with poultry feed at different concentrations. This study aimed to understand the effect of local microorganism-based probiotic sourced from cattle rumen and chicken intestine and added as feed supplement at different concentrations on broiler meat quality. Materials and Methods: The local microorganism-based probiotic made from cattle rumen and chicken intestine contained Lactobacillus spp., Bifidobacterium spp., Streptococcus spp., and Bacillus spp. The experiments followed a completely randomized design. Treatments in the study were: P0, i.e., control (without probiotic), P1 (probiotic administered at 5 ml/kg feed), P2 (probiotic administered at 10 ml/kg feed), and P3 (probiotic administered at 15 ml/kg feed). Each treatment was repeated 5 times. Parameters examined in this study were pH, meat tenderness, fat content, and meat protein content. Results: Based on a total of 200 chickens, the percentage of meat protein content in treatments P1, P2, and P3 showed an increase of 19.34%, 19.42%, and 19.64%, respectively, when compared with P0 that showed a protein content increase of 19.14%. The fat content of meat for P1, P2, and P3 was 21.54%, 21.46%, and 21.30%, respectively, which was less than the value for P0 (21.69%). The treatments did not significantly affect pH or meat tenderness when compared with the control. The usage of this novel probiotic as a feed supplement resulted in an increase in meat protein content and a decrease in fat content. Conclusion: This study indicates that using the local microorganism-based probiotic sourced from cattle rumen and chicken intestine to supplement poultry feed did not have a significantly different effect (p>0.05) on meat pH; however, it had a significantly different (p<0.05) on protein and fat content of broiler meat.

The aim of study was investigate gastrointestinal disease on cow fed forage from Progo watershed. Sixty three feses samples were taken from cows on Progo watershed. The method of feses analysis used was sentrifuge and Parfitt Bank. The results showed that 63 samples of cows feces were examined, among 25 were infected by Fasciola sp., 7 Paramphistomum sp., 14 Strongyle, and 9 Coccidiosis. The conclusion was the prevalence of gastrointestinal disease in cows was dominant incidence of Fasciolosis by 40%, Strongyle 22%, 14% Coccidiosis, and Paramphistomum sp.11%.

Parasit cacing (Helminth) merupakan kendala kesehatan yang berhubungan dengan investasi parasit sering dijumpai pada ayam. Penelitian ini bertujuan untuk mengidentifikasi keragaman parasit cacing yang terdapat pada ayam kampung di Kabupaten Jember. Prosedur pengambilan sampel ekskreta ayam kampung dilakukan secara acak. Sampel ekskreta yang diambil sebanyak 150 sampel di Kabupaten Jember. Identifikasi keragaman spesies cacing dilakukan melalui pemeriksaan telur cacing pada sampel ekskreta dengan metode sedimentasi yang dilakukan di BBVet (Balai Besar Veteriner) Wates, Yogyakarta. Parasit cacing yang teridentifikasi pada sampel ekskreta ayam kampung merupakan cacing dari kelas Nematoda yang terdiri dari Capillaria sp. (24,67%); Heterakis sp. (10,67%); Strongyloides sp. (3,33%); dan Ascaridia sp. (2,67%).

One of several factors that can decrease productivity of laying chicken is health problems caused by worm parasite (helminthiasis). The aim of this research is to identify the diversity of worm parasites in laying chicken in Jember District. Obtained information on worm parasite species can be used as a database for prevention and treatment strategies of helminthiasis in laying chicken in Jember District. One-hundred-and fifty laying chicken excreta samples were randomly collected in the Jember area which was started from July to August 2020. Identification of worm species diversity was carried out by examining worm eggs found in excreta samples using the sedimentation method and the Whitlock method performed at Balai Besar Veteriner (BBVet) Wates. Based on the results of chicken excreta examination in Jember, worm parasite eggs were found from the nematode class consisting of Strongyloides sp.; Heterakis sp., and Ascaridia sp.
