Cassava and sweet potato leaves are agricultural byproducts which are potential to be utilized as feed for small ruminants. In year 2009, it is assumed that dry matter productions of cassava and sweet potato leaves are 2,590,929 and 348,008 tons, respectively. Cassava and sweet potato leaves, both contain high level of protein (> 20%) so that they are good protein sources for goats. Cassava leaves, however, contain cyanide acid (HCN) that varied depended on the age and require wilting process before fed to goat. Several experiments on utilization of cassava or sweet potato leaves for small ruminants showed positive responses on animal performance and could replace 50% of concentrate feed. Besides, cassava leaves can reduce worm eggs while sweet potato leaves contain high lutein. At present, the development of cassava and sweet potato is expected to provide feed as byproduct for ruminant. Key words: Cassava, sweet potato, feed resource, ruminant

An experiment was conducted in Indonesian Research Institute for Animal Production (IRIAP) Bogor, West Java. The objective of this research was to study the production and nitrogen uptake of three short grasses species for grazing namely Paspalum notatum, Brachiaria humidicola, Stenotaphrum secundatum on different shading and fertilization. This experiment was arranged in split-split plot design. The main plot was shading level (0, 38, and 56%); sub-plot was fertilizer dosage (0, 100, and 200 kg N/ha) while sub-sub plot was grass species. Data were analyzed by analysis of variance, and continued with Duncan multiple range test (DMRT) if there were significantly different among treatments. The highest shoot production, shoot/root ratio, and crude protein content were observed on S. secundatum with 38% shading levels and 100 kg N/ha fertilizer. The higher shading level had the lower nitrogen uptake by plant, whereas the higher fertilizer dosage gave higher nitrogen uptake. Â Â Key Words: Shading, Fertilization, Production, Nitrogen Uptake

Biomass by-products or plant residues from the plantation system would play a crucial role in animal production since the utilization of forages from the underneath tree crops would be less or minimal when the palm oil crop mature. By-products generated from the palm oil system vary, but in relation to the animal production they could be generally categorized into the fibrous by-products and the non-fibrous (concentrate) by-products. Palm oil mill effluent (POME) and palm kernel cake (PKC) are concentrate by-products produced during the processing of palm oil extraction which have great potency to support sheep and goat production, although limiting factors such as contamination of shell and high copper level in PKC need to be considered in their utilization as feed. The fibrous palm oil by-products include oil palm fronds (OPF) and oil palm trunk (OPT) generated from the palm crop trees and oil palm empty fruit bunch (OPEFB) and palm pressed fiber (PPF) generated from processing of fresh fruits to yield crude oil. These fibrous by-products cannot meet the metabolisable energy required for high growth rate and for lactation of sheep and goats due to low DM digestibility, low crude protein content, low fermentable carbohydrate and low level of intake. Limited inclusion level in ration should be applied for those by-products to yield an acceptable production level of sheep and goats. Pretreatments (physical, chemical, and biological) gave some improvement in their nutritional qualities, however additional cost of pretreatments need to be considered. In the future, there would be a great challenge for the utilization of those fibrous by-products as animal feed since bioconversion of lignocellulosic materials to products such as chemicals (bioethanol, sugar, and bioplastic), fuels, and organic fertilizers are receiving greater interest. Some comparative advantages of these natural wastes are their relatively low cost, renewable and widespread in nature for used in an industrial operation.

Boerka goat is the best meat type goat. Feed quality is one of the biggest factors that affect productivity, so it is necessary to know in advance the need for nutrients. The purpose of this study was to determine the dietray of crude protein (CP) and Total Digestible Nutrients (TDN) in efficient feed for the production of Boerka goats male growing phase. This study was designed in a completely randomized design, consisting of six combination feed treatments with six replications. Namely: 1 (CP 13.00% and TDN 63.10%); 2 (CP 13.03% and TDN 65.07%); 3 (CP 13.00% and TDN 70.00%); 4 (CP 15.00% and TDN 62.69%); 5 (CP 15.12% and TDN 65.00%); 6 (CP 15.00% and TDN 70.00%). The observed variables were feed consumption, feed consumption ratio (FCR), nutrient digestibility (dry matter, organic matter, crude protein) and average daily gain (ADG). Results of this study show that the balanced of CP and TDN has no significant effect on consumption and FCR. However, it was significantly different for digestibility and ADG. Feed treatment (CP 13.03% and TDN 65.07%) obtained the higher digestibility of DM and OM (71.49 and 70.5%), while the highest CP digestibility was treated with CP 15.05% and TDN 62.69% (71.59%). The ADG response of Boerka goats with CP 13.03% and TDN 65.07% was the good results (144.90 g head-1day-1) while the lowest response was on CP 13.08% and TDN 63.10%. It is concluded that the dietray of CP 13.03% and TDN 65.07% is a recommended of Boerka goat male growing phase.
