| Abstract: | Domba merupakan ruminansia kecil yang berpotensi tinggi dalam pemenuhan protein hewani di Indonesia. Namun, faktor lingkungan seperti curah hujan dapat menimbulkan stres fisiologis yang akhirnya memengaruhi kesehatan ternak dan reproduksi. Penelitian ini bertujuan menganalisis hubungan curah hujan dengan rasio neutrofil/limfosit (N/L) sebagai parameter indeks stres dan kualitas semen pada domba. Penelitian dilakukan pada empat ekor domba jantan dewasa selama Desember 2024 hingga April 2025. Parameter yang diamati meliputi curah hujan (CH), rasio N/L, dan parameter kualitas semen meliputi volume semen, motilitas progresif (%M), konsentrasi, viabilitas (%V) dan abnormalitas (%Abn). Data rasio N/L dan kualitas semen diambil sebanyak 9 ulangan. Semua parameter dianalisis deskriptif dan dilakukan uji korelasi dan regresi. Hasil menunjukkan bahwa CH selama periode penelitian adalah termasuk musim hujan, profil diferensial leukosit termasuk normal dan kualitas semen adalah baik. Hasil analisis menyatakan bahwa CH berkorelasi negatif kuat dan berpengaruh tidak signifikan (p>0,05) terhadap rasio N/L dan %V; berkorelasi sangat kuat dan berpengaruh signifikan terhadap volume semen dan konsentrasi spermatozoa; berkorelasi negatif sangat kuat dan berpengaruh signifikan terhadap %M; serta berkorelasi lemah dan berpengaruh tidak signifikan terhadap %Abn. Disimpulkan bahwa pada musim hujan, curah hujan tidak memengaruhi level stres, namun memengaruhi kualitas semen domba. Ram are small ruminants that have high potential in fulfilling animal protein needs in Indonesia. However, environmental factors such as rainfall can cause physiological stress that ultimately affects the animal health and reproduction. The study aims to analyze the correlation between rainfall and the neutrophil/lymphocyte ratio (N/L) as a parameter of stress index and semen quality in rams. The study was conducted on four rams from December 2024 to April 2025. The parameters observed included rainfall (CH), N/L ratio, and semen quality parameters such as semen volume, progressive motility (%M), sperm concentration, sperm viability (%V), and sperm abnormality (%Abn). Data on the N/L ratio and semen quality were collected in nine replicates. All parameters were analyzed descriptively, and then subjected to correlation and regression tests. The results showed that CH during the study period was within the rainy season, leukocyte differentiation profiles were normal, and semen quality was good. The analysis results indicated that CH had a strong negative correlation but no significant effect (p>0.05) on the N/L ratio and %V; a very strong correlation and significant effect on semen volume and concentration; a very strong negative correlation and significant effect on %M; and a weak correlation and no significant effect on %Abn. It is concluded that during the rainy season, rainfall does not significantly affect stress levels, but affects the quality of ram semen. |
