Fasciolosis is a disease caused by the genus Fasciola which attacks wild animals, livestock and humans. Molecular characterization of Fasciola sp. important for identifying the species Fasciola sp. The aim of this research was to analyze the characteristics of the worm Fasciola sp. molecularly on samples of cattle slaughtered at the Kediri City Slaughterhouse Regional Technical Implementation Unit. This research was carried out from January to February 2023. The samples were adult worms Fasciola sp. taken from one beef cattle and one dairy cattle. The PCR used is conventional PCR with primers from mitochondrial DNA genes. PCR products are passed to the sequencing stage. The PCR test results read on 2% agarose gel electrophoresis showed that the PCR product had high specificity, namely forming a single band at position 752 bp showed positive for F. gigantica. the results of the phylogenetic tree of Fasciola sp. with data in GenBank showing Fasciola sp. beef and dairy cattle isolates in Kediri City are closely related to Fasciola sp. dairy cattle isolate from China with Accession Number KF543343.1 and Fasciola sp. long-haired cattle (yak) isolate from China Accession Number MH621335.1. The existence of international livestock trade can result in the introduction of various diseases, one of which is Fasciolosis. Livestock import-export activities from China allow the introduction of Fasciola sp. to Indonesia.

Ten cattle with severe generalised skin lesions due to dermatophilosis were taken up for the study. Typical exudative dermatitis lesions with matting of hairs, thick scab formation and fissures on the skin were noticed in lower limbs, udder, perineum, inguinal region, axilla, neck and ears. Haematological analysis revealed anaemia and an increase in the absolute eosinophil count in affected animals. Serum biochemical estimations revealed hypoalbuminaemia, hyperglobulinaemia, a decrease in A/G ratio, increase in the blood urea nitrogen value and decrease in the zinc level in affected animals

The quantum of inclusion of concentrates in cattle feeding depends solely on availability and its price. An attempt was made to model and forecast the feed prices of dairy cattle feed in Tamil Nadu using time series data collected from Central Feed Technology Unit, Kattupakkam for the period from January 2012 to December 2022. Various time series models viz., Mean, Naïve, Random drift, Seasonal naive, Simple Exponential Smoothing, Holt linear, Holt-winter, Autoregressive Integrated Moving Average - ARIMA and Seasonal Autoregressive Integrated Moving Average models were fitted. The error measures, parameter estimates, forecast estimates and plots were assessed to ascertain the best fit model. Random drift model and ARIMA (0,1,0) model were found to be the best fit models for dairy cattle feed. Further, Holt-winter multiplicative model and SARIMA (1,1,0)(1,0,1) model were identified as the best fit models for the dry cattle feed price forecasting. Thus, these models could be utilized by the various stakeholders to predict the short term price forecasts of cattle feed for efficient planning and making right decisions. 

Objective: Different sources and levels of starch in the total mixed ration might result in different rumen fermentation profiles, rumen microbial composition, and enteric methane production. The current study aimed to evaluate the effect of dietary starch intake on enteric methane production through a meta-analytical approach by integrating related published studies. Materials and Methods: Papers that provided study results on enteric methane production from cattle fed different sources and levels of starch were selected. A total of 52 publications were filtered based on some specified criteria, comprised of 73 studies focused on enteric methane production in cattle fed a basal diet supplemented with starch. The collected data were subjected to statistical meta-analysis through a mixed methodology model. The p-value and root mean square error (RMSE) were applied as the statistical models. Results: Results showed that increasing the level of dietary starch intake and its digestibility in the rumen as well as increasing propionate significantly decreased the acetate to propionate (A/P)ratio as well as enteric methane production (p < 0.01). Conclusions: It is concluded that the addition of starch to diets mitigates enteric methane production from cattle, primarily through two ways, i.e., manipulation of the protozoa population and alteration to a lower A/P ratio.

Objective: To isolate and characterize cellulolytic rumen bacteria from the rumen of Sahiwal cattle using rumen bacterial inoculum to increase the nutritional value of rice bran used as broiler feed. Materials and Methods: The ruminal liquid was kept at an optimal pH of 6.9 and a redox potential of less than −300 mV while being incubated anaerobically at 39°C in a medium containing rumen fluid glucose cellobiose agar. By using the Hungate technique, the organisms were detected based on their morphological, physiological, biochemical, and molecular testing. Results: The findings revealed that the isolated Ruminococcus albus, and Ruminococcus flavifaciens were obligate anaerobic, generally Gram-positive, nonmotile cocci or rod, single or pair, occasionally short chain, producing yellow pigment when grown on cellulose, and having a clear zone around the colonies. Both isolate fermented sugars such as cellobiose, glucose, and lactose, as well as decomposed xylan. The results also showed that the isolates recognized as Ruminococcus spp., a cellulolytic rumen bacterium, were catalase-negative, indole-negative, and gelatin liquefaction-positive. Conclusion: Isolation and characterization of Ruminococcus spp. may be helpful for Bangladesh in reducing the cost of producing poultry feed and circumventing restrictions on rice bran use. We can also develop more efficient and long-lasting plans to enhance poultry performance and feed efficiency, as well as increase the nutritional value of rice bran used as broiler feed, by understanding how various Ruminococcus spp. function in this process.
