Dwarf Elephant Grass

Relatively short grazing periods in a pure legume pasture can be an alternative for increasing animal performance in medium-quality tropical pastures. Thus, the aim was to evaluate the herbage intake and animal performance of steers grazing dwarf elephant grass (Pennisetum purpureum Schum. cv. BRS Kurumi) with two access times [2 h (07:00 - 9:00) and 6 h (07:00 - 13:00)] to an area of forage peanut (Arachis pintoi cv. Amarillo). Twelve steers (219 ± 28.8 kg LW) were divided into four groups and assessed during three consecutive grazing cycles, from January to March 2013. The crude protein and neutral detergent fiber contents were 158 and 577 g/kg dry matter (DM) for dwarf elephant grass and 209 and 435 g/kg DM for forage peanut, respectively. The pre-grazing height and leaf mass of dwarf elephant grass and forage peanut were 94 cm and 2782 kg DM/ha and 15 cm and 1751 kg DM/ha, respectively. The herbage intake (mean = 2.7 ± 0.06% LW) and average daily weight gain (mean = 1.16 ± 0.31 kg/day) were similar for both treatments. However, animals with 2-h access to the legume paddock grazed for 71% of the time, whereas those with 6-h access grazed for 48% of the time. The performance of the steers that were allowed to graze forage peanut pasture for 2 h is similar to that of those that were allowed to graze the legume pasture for 6 h.

Abstract: The objective of this work was to evaluate the nutritional value of silages from tall-sized and dwarf elephant grass (Pennisetum purpureum) genotypes, intercropped or not with butterfly pea (Clitoria ternatea). The experiment was performed in randomized complete blocks, in a 4x2 factorial arrangement (four genotypes × two cropping systems). The genotypes intercropped or not with butterfly pea were: IRI-381 and Elephant B, tall sized; and Taiwan A-146 2.37 and Mott, dwarf. Forage was harvested 60 days after regrowth. In the silage from Mott grass intercropped with butterfly pea, lower contents of lignin (78.1 g kg-1), neutral detergent fiber (636.0 g kg-1), and neutral detergent insoluble protein (13.15 g kg-1), besides a greater dry matter recovery (873.3 g kg-1), were observed. The silage from Taiwan A-146 2.37 intercropped with the legume showed a greater crude protein content (136.1 g kg-1). In both silages, the ammonia nitrogen contents were quite reduced (26.4 g kg-1). However, greater residual water-soluble carbohydrate contents were observed in the silages from the intercrop (1.85 mg g-1) and from the Mott grass monocrop (1.51 mg g-1). Moreover, there was a lower in vitro dry matter digestibility (676.7 g kg-1) for the silage from the intercrop. Dwarf genotypes increase the nutritional value of elephant grass silage, compared with the tall-sized ones. Intercropping with butterfly pea improves silage fermentation characteristics, despite reducing its digestibility. Therefore, the ensilage of dwarf Mott elephant grass intercropped with butterfly pea shows more promising results.

The objective was to evaluate the productivity, chemical composition, ruminal degradability of dry matter and digestibility of BRS capiaçu grass (Pennisetum purpureum Schum.) managed at five regrowth ages. A completely randomized design with ten replications was used in the BRS capiaçu elephant grass subjected to five cutting intervals (30, 60, 90, 120 and 150 days) in the summer, making a total of 50 plots with a useful area of 4 x 2 m. There were daily increases in the dry matter production in the order of 382 kg ha-1, with 49,859 kg ha-1 being produced at 150 regrowth days. The dry matter content and organic matter linearly increased (P < 0.01) at different regrowth ages. The crude protein content, in vitro dry matter digestibility and in vitro digestibility of neutral detergent fiber linearly reduced (P < 0.01) 0.037%, 0.196% and 0.256% per day, respectively. Potential degradability of dry matter decreased from 68.9% at 30 days to 44.7% at 150 regrowth days (0.194 percentage units per day). The rate of degradation of fraction B 'c' was not modified (P = 0.94), averaging 1.46% hour-1. In the cultivation of BRS capiaçu elephant grass in the summer season, in the northern region of Minas Gerais, the age for harvesting between 90 and 120 days of regrowth is recommended.

<p>Coconut plantation area in North Sulawesi is an ecological basis for cattle but lower in terms of productivity of feed d annutrients. This study aims to improve the productivity of feed and nutrient  for beef cattle development in the coconut palm plantation through the introduction of superior forage P. purpureum Schum cv. Mott. The study was conducted from July 2012 to January 2013, in the Ongkaw Village, South Minahasa Regency, North Sulawesi. Coconut palms used in this study was 50 years-old tall coconuts with planting system of  9 m x 9 m at farmer plantation area. The research followed a completely randomized design with three treatments and three replications. The treatments tested were types of animal feed, which consists of (1). P. purpureum  Schum cv. Mott  (dwarf elephant grass),  Cynodon sp. (native grass), and P. purpureum (forage elephant grass). Planting systems of livestock forage are 20 cm x 20 cm, for Cynodon sp.  100 cm x 50 cm for  both  P. purpureum  Schum cv. Mott and P. purpureum. The first defoliation was done 70 days after planting, after that, the defoliation was done every 45 days. The result showed that the dry weight of animal feed/ha was 15.31 tons, 163.73   tons and 128.21 tons for Cynodon sp., P. purpureum  Schum cv. Mott and P. purpureum, respectively. Dry matter and nutrients of P. purpureum  Schum cv. Mott was higher than that of Cynodon sp. and P. purpureum. The result showed that the introduced P. purpureum  Schum cv. Mott significantly increased both animal feed production and feed nutrients in coconut plantation area as compared to the local forage crops (Cynodon sp. and P. purpureum). The P. purpureum  Schum cv. Mott can adapt to the shade of bearing coconut palms.</p><p>ABSTRAK </p><p>Lahan perkebunan kelapa di Sulawesi Utara merupakan basis ekologi sapi namun produktivitas dan nutrisi pakan rendah. Penelitian ini bertujuan meningkatkan produktivitas pakan dan nutrisi untuk pengembangan sapi potong di lahan perkebunan kelapa, melalui   introduksi hijauan pakan ternak unggul Pennisetum purpureum Schum cv. Mott. Penelitian dilaksanakan pada Juli 2012 sampai dengan Januari 2013 di Desa Ongkaw, Kabupaten Minahasa Selatan, Provinsi Sulawesi Utara. Tanaman kelapa yang digunakan dalam penelitian ini adalah Kelapa Dalam umur 50 tahun dengan jarak tanam  9 m x 9 m. Penelitian  menggunakan  Rancangan  Acak  Lengkap  dengan tiga perlakuan dan           tiga ulangan. Tiga perlakuan yang diuji adalah jenis pakan ternak, yang terdiri atas P. purpureum Schum cv. Mott, Cynodon sp. dan Pennisetum purpureum. Jarak tanam pakan ternak tersebut adalah 20 cm x 20 cm untuk Cynodon sp., dan 100 cm x 50 cm untuk P. purpureum Schum cv. Mott dan P. purpureum. Defoliasi pertama dilakukan 70 hst, setelah itu defoliasi dilakukan setiap 45 hari. Hasil penelitian ini menunjukkan bahwa berat kering pakan ternak per ha adalah 15,31 ton; 128,21 ton; dan 163,73 ton/ha berturut-turut untuk  Cynodon sp., P. purpureum, dan P. purpureum Schum cv. Mott. Bahan kering dan nutrisi pakan P. purpureum Schum cv. Mott  lebih tinggi dari Rumput Cynodon sp. dan Pennisetum purpureum. Hasil penelitian menunjukkan bahwa P. purpureum Schum cv. Mott  yang diindtroduksi meningkatkan produksi dan nutrisi pakan ternak pada lahan perkebunan kelapa secara nyata dibanding tanaman pakan lokal Cynodon sp. dan P. purpureum. Pennisetum  purpureum Schum cv. Mott  dapat beradaptasi di bawah naungan kelapa dewasa.<br /><br /></p><p> </p><p> </p>
