Abstract

This study was motivated by the importance of understanding the production performance of local sheep in Indonesia, particularly in Gucialit Village, Lumajang Regency, considering its significant role in meat production. This study aimed to examine the effect of age and sex on the production performance of local sheep, which includes body weight, chest girth, body length, and shoulder height. An observational method with a quantitative approach was employed. Local sheep were grouped based on sex (male and female) and age (<1 year, 1-1.5 years, and 1.5-2 years), followed by measurements of the aforementioned variables. Data were analyzed descriptively and statistically using a Completely Randomized Design (CRD). The results showed that age had a very significant effect (P<0.01) on all sheep production performance variables. As the age of the sheep increased, body weight, chest girth, body length, and shoulder height increased significantly. Sex differences also showed a significant effect on production performance. Male sheep had greater body weight, chest girth, body length, and shoulder height compared to female sheep within the same age group

Abstract

This study aimed to analyze population structure, disease case frequency, and post-vaccination antibody responses of Pampangan cattle and buffalo following Septicaemia Epizootica (SE) vaccination in Ogan Komering Ilir (OKI) Regency, South Sumatra. The research employed a quantitative longitudinal observational design based on secondary data collected from March to August 2024, including livestock population records, disease cases, vaccination coverage, and antibody test results measured using the ELISA method. Data were analyzed descriptively and inferentially through normality tests, independent t-tests, Mann–Whitney U tests, Chi-Square tests, and Kruskal–Wallis tests according to data distribution. The results indicated significant to highly significant differences in population structure between cattle and buffalo. Cattle populations were higher in total number (35,999 vs. 10,297 head), proportion of calves (17.48% vs. 14.54%) and young stock (25.05% vs. 23.25%), male–female ratio (66.38% vs. 62.03%), and replacement rate (40.61% vs. 38.79%). In contrast, buffalo showed higher proportions of adult animals (62.21% vs. 57.47%), breeding herd (38.84% vs. 35.75%), and potential dams (53.90% vs. 50.26%). Nevertheless, both cattle and buffalo met national standards for sex ratio and replacement indicators. The frequency of SE cases did not differ significantly between species; however, descriptively, increased vaccination coverage was associated with a decline in reported cases. Post-vaccination antibody responses were not significantly influenced by species, breed, or geographical area. In conclusion, SE vaccination proved effective in reducing disease spread and generating consistent immunity across livestock, despite existing differences in population structure.
