Abstract

Bovine Brucellosis is endemic in Polewali Mandar Regency with a prevalence above 2%. Control programs implemented through active and passive surveillance, public awareness of the impact of the disease, and tests and slaughter have not been able to reduce the prevalence rate. This study aimed to examine the impact and risk factors of brucellosis on the productivity of beef cattle in Polewali Mandar Regency. A total of 100 primary data from cattle farmers related to brucellosis were used in this cross-sectional study. Descriptive analysis was employed to determine the parameters that were important in the occurrence of brucellosis. To establish risk factors, a univariate logistic regression analysis was carried out and revealed that odds of infection were significantly higher in history of abortion (OR = 11.82, 95% CI: 4.08 - 34.19,   p < 0.001) and in gestational age (OR = 0.0214, 95% CI: 0.0063 - 0.0724, p < 0.001) and in dry season than wet season (OR = 14.89, 95% CI: 4.97 - 44.62, p < 0.001).  The brucellosis control program through mass vaccination must immediately become a recommendation for regional and central governments to reduce brucellosis transmission to prevent economic impacts and losses for farmers, particularly the public health risk.

Abstract

This study aimed to analyze the effect of dangke nuggets with the addition of corn flour on the physicochemical properties of dangke nuggets. This study used a completely randomized design (CRD) factorial pattern with three replications and three treatments. The first factor was corn flour addition level of 0%, 5%, and 10%, and the second factor was storage time of 0, 14, and 28 days in the freezer. Physicochemical testing included the Cooking Loss test, nugget breakability, water content, protein content, and fiber content. The results showed a correlation between the corn flour addition level and the storage time, which had a significant effect (P<0.01) on the Cooking Loss, water content, protein content, and fiber content of dangke nuggets. At the same time, there was no correlation between the corn flour addition level and the storage time for shear force, which had no significant effect (P>0.05). Based on the study, it can be concluded that the addition of 5% corn flour to the formulation can increase protein content. In comparison, adding 10% corn flour provides the best quality in terms of cooking loss, nugget-breaking power, and water content and increases the fiber content of the nugget. The longer the storage, the lower the water content and protein content, reducing the quality of cooking loss and nugget-breaking power.
