<p>The objective of this study was to evaluate the quantitative performance of thirty-six Krui cattle aged 18 to 36 months, raised on a traditional farm located in the Krui Selatan and Pesisir Selatan district, Pesisir Barat Regency, Lampung. A survey method using purposive sampling was employed to collect the samples. Body measurements, including body weight (BW), body length (BL), chest width (CW), chest circumference (CC), chest depth (CD), and hip circumference (HC), were recorded. The collected data were analysed descriptively. The findings revealed that BW, BL, CW, CC, CD, and HC of the Krui cattle in Krui Selatan District were: 175.40 ± 41.77 kg, 111.18 ± 5.74 cm, 28.18 ± 2.56 cm, 138.55 ± 16.88 cm, 52.73 ± 8.19 cm, and 18.00 ± 1.41 cm, respectively. At the same time, the Krui cattle's BW, BL, CW, CC, CD, and HC in Pesisir Selatan District were 154.23 ± 65.70 kg, 110.64 ± 9.36 cm, 24.86 ± 5.15 cm, 120.80 ± 11.2 cm, 47.67 ± 5.33 cm, and 17.64 ± 1.36 cm, respectively. This study concludes that the quantitative performance of Krui cattle in Traditional Farming in Krui Selatan District is greater than that of Krui cattle in Pesisir Selatan District. Still, more miniature compared to other local cattle breeds (Madura cattle, Bali cattle, Aceh cattle, Ongole grade cattle, and Jabres cattle) in Indonesia.</p>

<p>This study aimed to estimate the value of genetic correlation and the regression equation between body weight and body measurements of male Ongole crossbred (PO) cattle across various age groups. The sample used consisted of 80 male PO cattle divided into four age groups: I₀ (&lt;18 months), I₁ (18 to 24 months), I₂ (24 to 30 months), and I₃ (&gt;30 months). The parameters observed include body weight (BW), body length (BL), body height (BH), hip height (HH), and chest circumference (CC). Correlation and regression data were analysed using the Excel program; the regression between body weight and body size was analysed using the best subset regression method. The results showed a strong to robust genetic correlation between body weight and body size, with the highest correlation value in chest circumference (CC) in all age groups (0.92-0.98). The regression equations revealed that chest circumference had the highest regression coefficients (ranging from 2.36 to 3.87), indicating that it is the most reliable body size measurement for predicting body weight in PO cattle. This study concludes that chest circumference can be used as a reliable parameter to estimate the weight of PO cattle in various age groups, especially for farmers who do not have access to scales.</p>
