Abstract

Masalah pengenceran semen segar yaitu adanya pengaruh lama penyimpanan. Kelemahan ini dapat diatasi dengan perlakuan waktu pada semen segar. Penelitian ini bertujuan untuk mengetahui viabilitas dan derajat keasaman (pH) semen babi Landrace pada pengencer sitrat kuning telur yang disimpan selama 24 jam. Semen yang digunakan berupa semen segar dari pejantan babi Landrace berusia 1 tahun 8 bulan. Semen dikoleksi dengan metode manual menggunakan induk buatan. Penelitian ini dilaksanakan bulan Februari sampai Maret 2016 menggunakan metode eksperimen menggunakan Rancangan Acak Lengkap (RAL) dengan empat perlakuan (R1= 60 menit, R2 = 120 menit, R3 = 180 menit, R4 = 240 menit) dan empat ulangan sehingga terdapat 16 unit percobaan. Penelitian ini diawali dengan melakukan penampungan semen segar babi Landrace bertempat di Tunbakun, selanjutnya semen segar langsung dievaluasi makroskopis dan mikroskopis di Laboraturium Faperta Universitas Timor. Kemudian dilakukan perlakuan pengenceran terhadap semen segar dengan lama waktu 60 menit, 120 menit, 180 menit, 240 menit, setelah itu diamati viabilitas dan derajat keasaman (pH) semen. Hasil penelitian menunjukkan bahwa penambahan pengencer sitrat kuning telur dalam semen babi Landrace berpengaruh sangat nyata (P<0.01) terhadap viabilitas semen babi Landrace dengan persentase R1 60 menit 88.38%, R2 120 menit 52.63%, R3 180 menit 43.38%, dan R4 240 menit 24.00%. Penambahan pengencer sitrat kuning telur memberikan daya hidup terbaik dengan lama waktu penyimpanan selama 180 menit. Sedangkan untuk derajat keasaman (pH) tidak memberikan pengaruh yang nyata (P>0.05) dimana nilai rataan pHnya R1 60 menit 5.5, R2 120 menit 5.25, R3 180 menit 5.25 dan R4 20 menit 5.0.

Abstract

The purpose of this study was to determine the effect of adding probio in feed on live weight, carcass weight, breast weight, upper thigh weight, and lower thighs of broiler chickens. In this study 80 day old broiler chickens (DOC) were used. The method used was an experimental method with a completely randomized design (CRD) using 4 treatments and 4 replications. The treatments consisted of R0 = 100% commercial feed, R1 = 99.7% commercial feed + 0.3% probio, R2 = 99.5% commercial feed + 0.5% probio and R3 = 99.3% commercial feed + probio 0.7%. The results of analysis of variance showed that the use of probio in commercial feed had no significant effect on body weight, breast weight, upper thigh weight and lower thighs of broiler chickens but had a significant effect on carcass weight (P <0.05). The conclusion from the results of this study is that it can be concluded that the addition of probio in feed up to the level of 0.3% increases the weight of broiler chicken carcasses but does not affect the life weight, carcass percentage, weight and percentage of breast weight, percentage of thigh, upper thigh and lower thigh of broiler chickens at the age of 45 days.
