Abstract

This study aims to determine the response to selection based on variations in selection intensity for birth weight in Priangan sheep. The study was conducted at a local farm in Nenggeng Village, Darangdan Sub-District, Purwakarta Regency, using a case study approach. The data analyzed were derived from the recorded birth weights of 108 lambs, which were the progeny of 6 rams and 36 ewes. Data analysis used descriptive statistics and analysis of variance (ANOVA). The response to selection was calculated based on standard deviation, heritability, and selection intensity. The most optimal selection intensity was achieved with the use of 0.44% (1 male lamb) and 4.11% (10 female lambs). The results of the analysis indicated that the response to selection was 0.138 kg. If selection is applied to the current generation, the birth weight of the next generation is expected to increase from 2.17 kg to 2.308 kg.

Abstract

ORF disease is a contagious skin infection in sheep caused by a virus of the Parapoxvirus genus. The resulting scabby lesions can lead to decreased productivity and secondary infections. This study aimed to evaluate the effectiveness of citronella (Cymbopogon nardus) essential oil in accelerating the healing of ORF wounds. A total of 24 local sheep infected with ORF were divided into three groups: Group I (1% concentration), Group II (5%), and Group III (10%). The treatment solution was applied topically every two days over a 14-day period. The results showed that Group III had the fastest healing time. Citronella essential oil at 10% concentration was proven effective as a natural treatment for ORF and holds potential for further development in veterinary applications for sheep farmers.
