Abstract

Ovarium sebagai organ reproduksi utama pada sapi betina, berfungsi menghasilkan oosit yang penting dalam proses reproduksi. Kualitas oosit yang dihasilkan oleh ovarium sangat dipengaruhi oleh kondisi fisiologis dan ukuran ovarium itu sendiri. Pemahaman mengenai hubungan antara ukuran ovarium dan kualitas oosit sangat penting untuk meningkatkan efisiensi reproduksi pada sapi Bali. Oleh karena itu, penelitian ini bertujuan untuk mengetahui pengaruh ukuran ovarium sapi Bali terhadap kualitas oosit. Rancangan penelitian ini menggunakan rancangan acak kelompok (RAK) faktorial dengan 2 faktor kemudian mengelompokkan masing-masing faktor menjadi 3 kelompok dengan 9 ulangan. Faktor yang dilihat yaitu ukuran ovarium dan berat ovarium yaitu ovarium dengan volume ≤30 mm3, ovarium dengan volume 31-49 mm3 dan ovarium dengan volume ≥50 mm3. Analisis data menggunakan analysis of variance (ANOVA) dan uji lanjut beda nyata terkecil (BNT). Berdasarkan hasil penelitian yang telah dilakukan bahwa ukuran ovarium sapi Bali berpengaruh terhadap kualitas dan kuantitas oosit, ukuran ovarium sapi Bali yang optimal menghasilkan oosit ovarium dengan volume 31- 49 mm3 yaitu sebanyak 27 oosit atau 61,3% dari total ovarium yang dikoleksi.

Abstract

Prostaglandin and estrogen hormones are two types of hormones commonly used in heat synchronization aimed at inducing earlier estrus in livestock. This study aims to determine the success rate of artificial insemination (AI) in beef cattle synchronized in heat with different hormones. The research method used is a Completely Randomized Design (CRD) consisting of 3 treatments and 4 replications: P0 (natural estrus), P1 (prostaglandin injection), and P2 (estrogen injection). The parameters tested in this study include the percentage of estrus, intensity of estrus and time of estrus symptoms. The analysis used is Analysis of Variance (ANOVA). The results indicate that the percentage of cattle showing signs of estrus in all three treatments reached 100%. The intensity of estrus in each treatment was assessed in three categories: clear estrus (score 3+++), moderate estrus (score 2++), and low estrus (score 1+). The results showed that in P0 and P2, 50% of the cattle exhibited clear estrus and 50% moderate estrus, while in P1, 66.7% showed clear estrus and 33.3% moderate estrus. The onset of estrus symptoms in P0 occurred on average at hour <480 or days 18-20 from the first to the second estrus cycle, whereas in P1 and P2, it appeared at hour 48 or day 2 after injection.

Abstract

Prostaglandin and estrogen hormones are two types of hormones commonly used in estrus synchronization aimed at inducing earlier estrus in livestock. This study aims to evaluate the effectiveness of estrus synchronization using prostaglandin and estrogen hormones on Non Return Rate (NRR), Conception Rate (CR), and Service per Conception (S/C) in Beef Cattle. The research method is a field experiment, where female cattle are divided into several treatment groups based on the type of synchronization hormone used, namely P0 (natural estrus), P1 (prostaglandin injection), and P2 (estrogen injection). The parameters tested in this study are Non Return Rate (NRR), Conception Rate (CR), and Service per Conception (S/C). The data obtained were analyzed descriptively and calculated using the formulas for NRR, CR, and S/C. The results of this study show that the average NRR for the three treatments is 66.67%, with treatment P1 achieving the highest result of 83.33%, followed by P2 (66.67%) and P0 (50%). The highest CR was also obtained in treatments P1 and P2 with a percentage of 66.67%, while P0 was only 33.33%, with an overall average of 55.7%. For the S/C value, treatment P1 showed the highest efficiency with an average of 1.6 inseminations per pregnancy, followed by P2 (2.0) and P0 (3.33), with an overall average of 2, 31.

Abstract

Penggunaan bungkil inti sawit (BIS) dalam pakan broiler pada penelitian bertujuan untuk mengetahui respon konsumsi pakan, pertambahan bobot badan, konversi pakan dan IOFC ayam ras pedaging (broiler). Sebanyak 40 ekor broiler ditempatkan di dalam kandang unit percobaan menggunakan rancangan acak lengkap yang terdiri 5 perlakuan dan 4 ulangan. Perlakuan yang diberikan meliputi: P1= Pakan Basal, P2= Pakan Basal + 10% BIS, P3= Pakan Basal + 10% BISF, P4= Pakan Basal + 15% BISF dan P5= Pakan Basal + 20% BISF. Berdasarkan hasil statistik menggunakan analisis sidik ragam menunjukkan perlakuan tidak memberikan pengaruh yang nyata P<0,05) pada konsumsi pakan, pertambahan bobot badan, dan konversi pakan, namun memberikan pengaruh yang nyata (P<0,05) pada Income Over Feed Cost. Penggunaaan bungkil inti sawit terfermentasi (BISF) tidak memberikan pengaruh yang buruk sampai 20%, sehingga dapat dijadikan sebagi bahan pakan sibtitusi dedak padi.   Kata kunci: bungkil inti sawit, performa, ayam ras pedaging, Income Over Feed Cost
