Abstract

This study aims to evaluate the effect of adding papaya leaf juice added to egg yolk citrate diluting medium (S-KT) to assess its effect on the quality of boar sperm from crosses between landrace and duroc breeds. Fresh semen from boar aged 1.5 who were in good health and had received training in semen collection methods was used in the study. Six treatments and five repetitions were employed in an experimental setting as part of a completely random research design, namely: egg yolk citrate without papaya leaf juice (P0), egg yolk citrate + 0.5% papaya leaf juice (P1), egg yolk citrate + 1% papaya leaf juice (P2), egg yolk citrate + 1.5% papaya leaf juice (P3), egg yolk citrate + 2% papaya leaf juice (P4),  egg yolk citrate + 2.5% papaya leaf juice. All treatments are stored in a coolbox with a temperature of 15-20ºC. Every twelve hours, the spermatozoa's mobility, survival, form, and ability to migrate were assessed. With a motility of 53.00±2.73%, viability of 67.70±1.4%, abnormality of 6.00±0.70%, and survival of 54.60 hours (P<0.05), the P5 treatment with the addition of papaya leaf juice up to 2.5% produced the best outcomes at 48 hours of storage. In comparison to previous treatments, it can be said that adding 2.5% papaya leaf juice to the S-KT dilution medium improved the quality of the liquid semen produced by Landrace and Duroc cross boar

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.
