摘要：The experiment was conducted to evaluate the effect of probiotic and organic mineral complex (POMC) administration on performance and meat quality of local sheep. In this study, 6 sheep with an average initial body weight of 12.67±0.81 kg were arranged in a completely randomized design with 2 treatments and 3 replications. The treatments were T0: basal diet (control) and T1: basal diet + POMC. The basal diet consisted of forage and concentrate (60:40) with dry matter of feed intake as much as 5% of body weight. Dose of POMC used in this study was 15 g/d/head. The POMC contained lactic acid bacteria, i.e. Lactobacillus sp. (1x108 cfu/g) and S. cereviseae incorporated with micromineral Co (2 ppm), Cu (100 ppm), Fe (2.5 ppm), I (110 ppm) and Mn (100 ppm). The experimental period lasted for 11 wk (1 wk for adaptation and 10 wk for data collection). Data were analyzed using t-Student statistical test to compare the treatments. The results showed that POMC administration did not affect the body weight gain (BWG) (7.46 kg) compared to control (7.13 kg) while concentrate consumption (26.9 kg) of POMC was lower than the control (28.6 kg). Meanwhile POMC administration did not affect the meat quality (pH, moisture, cooking loss and tenderness), whereas the meat cholesterol was lower (34.25 mg/100g) than the control (38.87 mg/100g). It is concluded that administration of probiotic lactic acid bacteria combined with organic minerals decreases concentrate consumption and thereby potentially increases the animals energy utilization efficiency. In addition, the treatment also decreases the meat cholesterol content of local sheep.
其他摘要：Penelitian dilakukan untuk mengevaluasi pengaruh pemberian kombinasi probiotik dan mineral organik kompleks (POMC) terhadap performa dan kualitas daging domba lokal. Sebanyak enam ekor domba jantan dengan rataan bobot awal 12,67±0,81 kg dibagi secara acak ke dalam 2 perlakuan. Tiap perlakuan terdiri atas 3 ulangan dalam rancangan acak lengkap yang dianalisis menggunakan uji tStudent. Perlakuan terdiri atas T0: ransum basal (kontrol) dan T1: ransum basal + POMC. Hijauan dan konsentrat (60:40) diformulasi sebagai pakan basal, dengan proyeksi konsumsi bahan kering sebanyak 5% dari berat badan. Dosis POMC yang diberikan sebanyak 15 g/hari/ekor. POMC mengandung bakteri asam laktat Lactobacillus sp. (1 x 108 cfu/g) dan S. cerevisiae terkorporasi mikromineral Co (2 ppm), Cu (100 ppm), Fe (2.5 ppm), I (110 ppm) dan Mn (100 ppm). Percobaan dilakukan selama selama 11 minggu (1 minggu periode adaptasi dan 10 minggu periode koleksi data). Hasil penelitian menunjukkan bahwa pemberian POMC tidak mempengaruhi pertambahan berat badan domba (7,46 kg) dibandingkan kontrol (7,13 kg), namun menghasilkan konsumsi konsentrat yang lebih rendah (P<0,05) (26,9 kg) dibandingkan kontrol (28,6 kg). Pemberian POMC tidak mempengaruhi kualitas daging (pH, kadar air, susut masak dan keempukan), tetapi menghasilkan kadar kolesterol daging yang lebih rendah (34,25 mg/100g) dibandingkan kontrol (38,87 mg/100g). Dapat disimpulkan bahwa pemberian probiotik bakteri asam laktat yang dikombinasikan dengan mineral organik menurunkan konsumsi konsentrat yang berpotensi meningkatkan efisiensi pengggunaan energi dan juga menurunkan kadar kolesterol daging domba.
