Abstract

Forage is one of the supporting factors in planning animal production. Climate condition is one factor which influence forage production. This research attempted to map the class suitability of climate for seven forage species in Bali province and to analysis the level of vulnerability toward climate changes by using Geography Information System (GIS). The results showed that four from seven species observed have class suitability with climate S1. Rain climate factor was the important factor which was influence the climate unsuitability of forage in Bali province. The effect of climate change, such as La Nina 1998 caused positive and negative impacts towards the distribution of class suitability of climate at that year. The incident of La Nina caused the reduction of area of class suitability of S1, S2, and N climate, meanwhile increase the area of class suitability of S3 climate. On the other hand, some location of climate suitability class also changed due to climate change.

Abstract

Provision of animal feed in accordance with quality standards and adequate quantities has become a strategic need to increase livestock productivity and accelerate the availability and fulfillment of foodstuffs from livestock. In this regard, a survey research has been designed to study some of the local fodder plants that have superior potential as animal feed. Fodder plants are classified as superior feed varieties if they have properties: easy to breed, high productivity as a producer of forage and / or seeds, has a fast regrowth, is resistant to defoliation, resistant to grazing, resistant to environmental stresses, and palatable for livestock. Based on the results of the survey, several species of local animal feed plants that have superior characteristics have been found. One of them is a phasey bean plant (Macroptilium lathyroides (L.) Urb.). Phasey bean as a superior animal feed plant (TPT) besides being suitable for the above characteristics also has grown naturally in an area in Bali so it needs to be tested for its feasibility to be distributed throughout Bali. Keywords: phasey bean, superior legumes, tropical forage

Abstract

Tujuan penelitian ini adalah untuk mengetahui degradasi neutral detergent fiber (NDF) dan acid detergent fiber (ADF) dan protein kasar (PK) dari rumput raja (RR) secara in vitro menggunakan cairan feses sebagai inokulum. Sampel RR diambil dari Fapet Farm Fakultas Peternakan Universitas Jambi, kemudian dipotong-potong dengan ukuran panjang 5 cm kemudian dikering dan digiling dengan ukuran 1 mm mash. Feses dan cairan rumen diambil dari satu ekor sapi berfistula rumen. Sampel kemudian diinkubasi untuk mengetahui degradasi NDF, ADF dan PK. Penelitian ini menggunakan Rancangan Acak Lengkap (5x4) dengan lima perlakuan sebagai berikut A (Cairan rumen (kontrol)), B (Cairan feses), C (Cairan feses dan 2,5% gula), D (Cairan feses, 2,5% gula dan 2,5% urea) dan E (Cairan feses dan 2,5% urea). Hasil percobaan menunjukkan bahwa degradasi in vitro NDF dan ADF dari RR menunjukkan perbedaan nyata (P<0,05). Dapat disimpulkan bahwa penggunaan cairan feses dan penambahan gula sebagai sumber energi dan urea sebagai sumber nitrogen belum optimal yang terlihat dari masih rendahnya degradasi ADF dan PK kecuali NDF jika dibandingkan dengan penggunaan cairan rumen.

Abstract

The experiment that aimed to study the types and various levels of manure for improving growth and production of sweet corn was conducted for 9 weeks. Completely randomized design (CRD) arranged with nested model was used in this experiment. The main plot consisted of three kind of manures, there were broiler manure (A), horse manure (K), and pig manure (B). As sub plot were levels of manure: without manure D0 (0 ton/ha), D1 (10 ton/ha = 87.51 g/pot), D2 (20 ton/ha = 175 g/pot), D3 (30 ton/ha = 262.5 g/pot), with three replication in each combination treatment. Variables measured in this experiment were plant high, stem diameter, fresh and dry weight of leaf, stem and maize-ear of corn, total dry weight of forage production (stem + leaf) and dry weight ratio of stem and leaf of sweet corn. The result of the experiment showed that the effect of broiler, horse, and pig manure on all variables which measured in the experiment were not significantly different (P>0,05). The highest growth and production of sweet corn were obtained at 20 ton/ha level for all kind of manures that used in this experiment with total dry weight of forage production 48.88; 51.11; and 48.30 g/pot and dry weight of maize-ear production 23.80; 23.30 and 22.00 g/pot for broiler, horse and pig manure respectively. Based on results of the experiment it can be concluded that no different effect on type of manure (broiler, horse and pig) to the growth and production of sweet corn and the using manure at 20 ton/ha level give the highest growth and production of sweet corn.

Abstract

Forage is the main feed that contains almost all the nutrients needed by ruminants. This study aimed to determine the productivity of Panicum maximum, Setaria splendida Stapf, and Pennisetum purpureum grass were given organic fertilizer and knew the best organic fertilizer for each type of grass. The study used a completely randomized design in split plot pattern. The first factor (main plot) consists of three types of grass; Panicum maximum, Setaria splendida, and Pennisetum purpureum. The second factor (sub plot / subplot) is a type of organic fertilizer; without fertilizer, manure, compost, and vermicompost. Each treatment was repeated three times so that it consisted of 36 experimental units. The results showed that the interaction between the treatment of the type of organic fertilizer with the type of grass occurred in the variable number of tillers and the dry weight of the stem. The types of compost in significant can increase the number of tillers, the number of leaves, the dry weight of the stems, the dry weight of the leaves, and the total dry weight of forage, compared to without fertilizer. The type of grass has a significant effect on all observed variables. Based on the results of the study it can be concluded that the interaction between the treatment of the type of organic fertilizer with the type of grass affects the number of tillers and the dry weight of the stem, the three types of grass have different productivity, while among the organic fertilizers provided, compost gives the best results. Keywords: grass, manure, compost, vermicompost

Abstract

Teknologi pengolahan pakan diperlukan untuk mempertahankan ketersediaan pakan, meningkatkan kualitas pakan dan mengoptimumkan produksi ternak ruminansia. Teknologi pengolahan silase sudah lama dikenal. namun dengan perkembangan riset maka pengolahan silase dengan penggunaan berbagai metode telah banyak dikembangkan. Limbah organik pasar seperti limbah sayur-sayuran dapat menggantikan hijauan dikala musim kering. Tulisan ini merangkum sejumlah penelitian mengenai pemanfaatan teknologi silase dan produknya sebagai pakan ternak ruminansia yang telah dipublikasi di jumal atau prosiding lokal dalam beberapa tahun terakhir. Mikroorganisme digunakan untuk pembuatan silase terutama untuk meningkatkan kualitas limbah organik pasar dan fungsi rumen. Teknologi silase ini akan memberikan prospek yang semakin baik untuk meningkatkan produktivitas ternak ruminansia akan tetapi harus terus ditunjang oleh penelitian yang lebih spesifik dan mendalam tentang pemanfaatan silase limbah organik pasar pada ternak ruminansia. Kata kunci: teknologi silase, mikroorganisme, limbah pasar, ruminansia
