Penelitian bertujuan untuk mengetahui pengaruh varietas dan jarak tanam yang berbeda terhadap kandungan nutrisi hijauan jagung. Penelitian dilakukan pada bulan Desember 2018  hingga Juni 2019 di Laboratorium Lapang Terpadu dan Laboratorium Nutrisi dan Makanan Ternak, Jurusan Peternakan, Fakultas Pertanian, Universitas Lampung. Perlakuan dilakukan secara eksperimental menggunakan Rancangan Acak Kelompok Faktorial. Faktor pertama adalah varietas jagung (A = Bisi-18, B = NK 212, C = Pioneer 36) dan faktor ke dua jarak tanam jagung (J1= 60x20 cm, J2=80x20 cm). Tahapan penelitian mencakup tujuh tahap yaitu tahap pembuatan kompos kotoran sapi, persiapan lahan dan penanaman, pemupukan, pemeliharaan hijauan, panen dan pascapanen, pengambilan sampel, serta tahap analisis proksimat. Setiap perlakuan dikelompokkan berdasarkan ketinggian lahan menjadi kelompok 1, kelompok 2 dan kelompok 3. Peubah yang diamati adalah kandungan nutrisi bahan organik, protein kasar, lemak kasar, serat kasar dan Total Digestible Nutrient hijauan jagung. Hasil penelitian menunjukkan tidak terdapat interaksi antara perlakuan varietas dan jarak tanam. Perlakuan varietas serta jarak tanam tidak berpengaruh nyata terhadap kadar protein kasar, lemak kasar dan serat kasar hijauan jagung. Kata kunci : Analisis proksimat, Hijauan jagung, Jarak tanam, Kandungan nutrisi, Varietas jagung.

This research aimed to determine the effect of fermentation and ammoniation treatment of cassava peels on ration on dry matter digestibility (DMD) and organic matter digestibility (OMD) in male sheeps. This research was conducted in May--June 2019 in the cage unit and the Laboratory of Nutrition and Animal Feed, Department of Animal Husbandry, Faculty of Agriculture, University of Lampung. The experimental design applied was a completely randomized design (CRD) with 3 treatments and 3 replications. The experimental unit used were 9 sheeps. The treatments given were ration+15% cassava peels without treatment (R0), ration+15% fermented cassava peels (R1), and ration+15% ammoniated cassava peels (R2). The results showed that the use of cassava peel fermentation and ammoniation treatment had a significant effect (P<0.05) on dry matter digestibility (DMD) and organic matter digestibility in male sheep. The average of total digestibility of dry matter and organic matter of ration showed an increase of digestibility. The treatment of fermentation and ammoniation gave the best effect when compared to that without processing.   Keywords: Ammoniation, Fermentation, Cassava peels, Dry matter digestibility and organic matter digesbility, Sheep

This research intended to determine the effect of palm oil tree shade and mixed planting on grass and leguminous on productivity.  This research has been done on March—June 2018 in Tanjung Agung Area, Katibung District, Kalianda, South Lampung. This research used Completely Randomized Design (CRD) with split plot design method.  The treatment was implemented in this research is (1) shading, consist of two levels, which are N0 (without shade) and N1 (palm oil tree shade) and (2) mixed plant species, consist of two variations; which is A1 (elephant grass and purple bush bean) and A2 (dwarf elephant grass and purple bush bean).  The data which obtained were analyzed by analysis of variance on 5% significant level, then if the result significantly difference, it were analyzed with Duncan Multiple Range Test (DMRT).  The results showed that palm oil shading has not significant effect on grass productivity. there is an interaction between the type of grass and oil palm shade on the number of elephant grass and odot grass tillers. The dry matter of grass on mixed planting on land without shade was significantly different with dry matter of grass on mixed planting in palm oil shade.  However, it has tendency to increase organic matter of grasss on palm oil shade. Keywords: Palm Oil Shade, Elephant Grass, Dwarf Elephant Grass, Mixing Grass, Productivity

This study aimed to determine the best dose of purslane flour on total plasma protein, albumin, and globulin in Jawarandu Goats. This research was conducted in February-March 2021 at the Rambon Asri Farmer Group, Rejo Asri Village, Seputih Raman District, Central Lampung Regency, Lampung Province. Examination of total plasma protein, albumin, and globulin was carried out at the Veterinary Center of Lampung Province. The experimental design used was a completely randomized design (CRD) with 4 treatments and 5 replications. The treatments were basal ration (P0), basal ration with 5% purslane flour supplementation (P1), basal ration with 10% purslane flour supplementation (P2), and basal ration with 15% purslane flour supplementation (P3). The data obtained were analyzed using analysis of variance with a significance level of 5%. The results showed that purslane flour supplementation had no significant effect (P>0.05) on total plasma protein, albumin, and blood globulin of Jawarandu Goats but remained in the normal range.   Keywords : Albumi, Globulin, Jawarandu goat, Purslane flour, Total plasma protein

This research intended to determine the effect of using fermented and ammoniated of cassava peel on body weight gain and feed convertion in male sheep.  This research was conducted in June until August 2019 in a cage unit located in the Animal Husbandry Department, Agriculture Faculty, Lampung University.  The research used Completely Randomized Design with 3 treatments and 3 replications.  Experimental unit of this experiment were nine sheeps.  The treatment used were P0 (Ration + 15% cassava peel without processing), P1 (Ration + fermented cassava peel), and P2 (Ration + ammoniated cassava peel).  Variable in this study were feed intake, body weight gain, and feed conversion.  The data obtained were analyzed for variance with significance level 5%.  The results showed that the use of fermented and amoniated of cassava peel was not significant (P>0,05) on feed intake, body weight gain, and feed conversion.  Conclusion of this research is that fermented and ammoniated of cassava peel use in ration did not significantly increase body weight of sheep.   Key words: Amoniation, Body weight gain, Cassava peel, Feed convertion rate, Fermentation
