This study aimed to find out the compoSItion and distribution of thin-tailed sheep’s carcas tissue fed with green concentrate feed on the different breeding system. A total of 20 female thin-tailed sheep around 1 year old with an average initial weight of 18.3 ± 2.01, intenSIvely and semi-intenSIvely nurture for 119 days. Feed was given in the form of brachiaria humidicola grass and green concentrate with commercial concentrate as a control. Green concentrates and commercial concentrates are given in the morning at 07.00 and grass is given at 11.00, with a ratio of 40:60%. Concentrates were given with different nurture systems was carried out with four treatments, namely five sheep grazed for 6 hours with commercial concentrate feed (SIKK), five sheep grazed for 6 hours with green concentrate feed (SIIZ), five sheep grounded with grass feed and commercial concentrates (IKK), and five sheep are grounded with grass feed and green concentrate (IIZ). The experiment was carried out in a completely randomized factorial pattern with 2×2 treatments and 5 replications with initial weights as a correction factor. The results showed that sheep that were given green concentrates had lower weight, carcass weight, lower fat weight compared to commercial concentrates. However, with semi-intenSIve nurture it produces weight and percentage of muscle that is not much different from sheep that are given commercial concentrates.
Pengeringan bertujuan untuk mengurangi kadar air sehingga dapat meningkatkan daya tahan dan kualitas bahan pakan terutama jagung. salah satu metode pengeringan yang dapat digunakan yaitu pengeringan lapis tipis. Metode ini dapat menghilangkan air atau pelarut dari lapisan tipis bahan yang diterapkan pada suatu permukaan, sehingga tujuan dari penelitian ini adalah untuk mengetahui pengaruh pengeringan lapis tipis pada jagung (kadar air, moisture ratio, dan laju pengeringan) sebagai bahan pakan dengan tingkat suhu pengeringan yang berbeda-beda yaitu pada suhu 50, 60 dan 70 °C. Kadar air konstan yang diperoleh pada pengeringan suhu 50 °C mencapai 22.92%, pada suhu 60 °C mencapai 21.58%, sedangkan pada suhu 70 °C mencapai 17.58%, namun kadar air yang dihasilkan pada penelitian ini belum memenuhi standar kadar air yang dibutuhkan dalam penyimpanan bahan pakan (14%). Semakin tinggi suhu pengeringan yang digunakan maka akan semakin singkat proses pengeringannya dan pengurangan air bahan akan semakin cepat, mengakibatkan nilai Ln MR semakin menurun. Pada suhu pengeringan 50 °C diperoleh nilai rata-rata Ln MR= -2.4796 (R2=0.969), suhu 60 °C diperoleh nilai Ln MR= -2.7369 (R2=0.951), sedangkan pada suhu 70 °C dengan rata-rata Ln MR= -4.2102 (R2=0.977). Pada laju pengeringan pada suhu 60 °C lebih rendah dibandingkan dengan suhu 70 °C yaitu berkisar 0.44 gram/jam, sedangkan laju pengeringan pada suhu 70 °C yaitu mencapai 0.73 gram/jam. Dari hasil uji statistik dari ketiga level suhu pengeringan menunjukkan bahwa estimasi intercept tidak signifikan secara statistik pada level signifikansi 0.05.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
