Abstract

Penelitian ini bertujuan untuk menguji pengaruh penambahan level sari buah anggur (SBA) dalam pengencer Sitrat-kuning telur (S-KT) guna mempertahankan kualitas spermatozoa babi persilangan landrace x duroc selama penyimpanan. Penelitian ini menggunakan semen segar yang berasal dari seekor babi persilangan landrace x duroc yang berumur 1,5 tahun dalam kondisi yang sehat dan sudah terlatih dalam penampungan semen. Penelitian ini dirancang menggunakan rancangan acak lengkap yang terdiri dari lima perlakuan dan lima ulangan yakni: P0 = S-KT, P1: S-KT + SBA 3%, P2: S-KT + SBA 6%, P3: S-KT + SBA 9%, P4: S-KT + SBA 12%. Semen yang telah diencerkan disimpan dalam styrofom box pada suhu 18-20oC.Variabel yang diuji meliputi: motilitas, viabilitas, abnormalitas, dan daya tahan hidup spermatozoa. Data yang dikumpulkan dianalisis dengan Analisis of Variance dan dilanjutkan dengan uji Duncan. Hasil penelitian menunjukkan bahwa perlakuan P3 pada jam pengamatan ke-60 menghasilkan kualitas spermatozoa dengan perbedaan nilai yang signifikan (P0,05) dibandingkan perlakuan lainnya dengan nilai motilitas: 57,00%, viabilitas: 66,50%, abnormalitas: 5,10%, dan daya tahan hidup spermatozoa: 56,28 jam. Simpulan dari penelitian ini adalah penambahan sari buah anggur dengan level 9% dalam pengencer Sitrat-kuning telur memberikan respon yang terbaik dalam mempertahankan kualitas spermatozoa babi persilangan landrace x duroc.

Abstract

This study aimed to analyze the relationship between linear body measurements including chest girth (CG), body length (BL), and wither height (WH) and body weight (BW) in Rote sheep ewes across different age groups to determine the most reliable predictor of body weight. The research employed a quantitative method through direct field measurements and weighing. Data collected including vital statistics (CG, BL, WH) and BW from Rote sheep ewes categorized into three age groups (I0, I2, and I4). The data were analyzed statistically using correlation coefficient (r), the coefficient of determination (R²), and bias analysis to evaluate the accuracy of weight estimation. The results revealed that chest girth exhibited the highest correlation with body weight, particularly in the I0 group (r = 0.93; R² = 86.05%), indicating a strong positive relationship and high predictive accuracy. Body length showed a moderate relationship (r = 0.87; R² = 76.11%) in the same group, while wither height demonstrated a relatively weaker correlation (r = 0.73; R² = 53.94%). Across all age groups, the predictive strength of body measurements decreased with increasing age, suggesting that skeletal growth contributes less to body weight variation in mature sheep. In conclusion, chest girth was identified as the most accurate and reliable linear measurement for predicting body weight in Rote sheep ewes, particularly in younger age groups, and can therefore be used as a practical and non-invasive tool for estimating livestock weight.
