Karakteristik Estrus dan Keberhasilan Kebuntingan Calon Induk Domba Garut yang Diberi Konsentrat dengan Kandungan Protein Berbeda

Abstract

Penelitian ini bertujuan menganalisis pengaruh konsentrat terstandar yang ditingkatkan kandungan protein kasarnya (PK) terhadap karakteristik estrus dan keberhasilan kebuntingan calon induk domba garut. Penelitian ini menggunakan 20 ekor domba Garut dara dengan rataan bobot badan 36,37 ± 4,04 kg dan ditempatkan di kandang kelompok. Penelitian ini menggunakan rancangan acak kelompok (RAK) dengan 2 perlakuan dan 5 kelompok. Ransum kontrol = rumput + konsentrat komersial (60:40) dengan PK 11% dan ransum perlakuan = rumput + konsentrat terstandar (60:40) dengan PK 14%. Variabel yang diamati meliputi karakteristik estrus, kebuntingan pertama setelah pemberian perlakuan, jumlah fetus, persentase kebuntingan, dan korelasi body condition score (BCS) dengan jumlah fetus. Data yang diperoleh dianalisis dengan independent sample T-Test. Hasil penelitian menunjukkan bahwa penggunaan konsentrat terstandar nyata menurunkan (P<0,05) suhu vulva, namun cenderung meningkatkan (P<0,1) lendir vulva. Warna dan bentuk vulva relatif sama antar perlakuan. Terdapat korelasi positif antara BCS dan jumlah fetus. Pemberian konsentrat terstandar dapat meningkatkan persentase keberhasilan kebuntingan dari 70% menjadi 90%.

This research aimed to analyze the effect of standardized concentrates that are increased in crude protein (CP) content on characteristics of estrus and success of the gestation of Garut female lamb. This study used 20 female lamb with an average body weight of 36.37 ± 4.04 kg and placed in group cages. This study used a randomized block design (RBD) with 2 treatments and 5 groups. Control ration = grass + commercial concentrate (60:40) with 11% CP and treatment ration = grass + standardized concentrate (60:40) with 14% CP. Variables observed included estrus characteristics, first gestation after treatment, number of fetuses, percentage of gestation, and correlation of body condition score (BCS) to the number of fetuses. The data obtained were analyzed with an independent sample T-Test. The results showed that the use of standardized concentrate significantly decreased (P<0.05) vulval temperature, but tended to increase (P<0.1) vulval mucus. Vulvar color and shape were relatively similar between treatments. There was a positive correlation between BCS and number of fetuses. Providing standardized concentrate can increase the percentage of successful gestation from 70% to 90%.
