KARAKTERISTIK KUANTITATIF SAPI LIMOUSIN DAN SIMMENTAL BERDASARKAN KELOMPOK UMUR DI RUMAH POTONG HEWAN LAMBARO

Abstract

This study aims to analyse the quantitative characteristics of Limousin and Simmental cattle based on age groups at the Lambaro Slaughterhouse, Aceh Besar Regency. The study used a comparative quantitative survey method with a 2 × 2 factorial design consisting of two breeds (Limousin and Simmental) and two age groups (2–3 years and 3–4 years). The parameters observed included body weight, chest circumference, body length, and height. Data were obtained through direct measurement, while body weight was calculated using the Winter Indonesia formula. Data analysis was performed using the Shapiro–Wilk test, Levene's test, and two-way analysis of variance (Two-Way ANOVA) at a significance level of 5%. The results showed that breed had a significant effect on body weight, chest circumference, and body length, but no significant effect on height. Age had a significant effect on all parameters observed. Simmental cattle had greater body weight, chest circumference, and height than Limousin cattle, while Limousin cattle had greater body length. There was no significant interaction between breed and age on all observed variables. It was concluded that the quantitative characteristics of beef cattle at the Lambaro Slaughterhouse were independently influenced by breed and age factors.
