Indigofera sp is a tree leguminous forage species known to be adaptable to the drought climate and saline soil and so it has potential as alternative feed resource to support the ruminant animal production. This study aimed to study the responses of goats fed Indigofera sp as the sole foliages in their diets. Twenty male Boer x Kacang crossbred goats (6 months of age;16 ± 2,1 kg BW) were randomly assigned to four dietary treatments containing fresh or wilted leaves of Indigifera sp. as the sole foliages and supplemented with high carbohydrate (HCC) or protein (HPC)concentrates. Consumable parts i.e. leaves and twigs of about 8 to 10 months of age of Indigofera sp. were harvested by hand plucking every day in the morning. The experiment was a 2 x 2 factorial design arranged in a completely randomized design. The ruminal pH ranged from 6.14-6.85 and were not affected (P > 0.05) by wilting nor by the type of concentrates. Wilting did not affect (P > 0.05) the concentration of ruminal NH3-N, but it was significantly higher (P < 0.05) in HPC group (32.36-32.54 mg dL-1) than those in HCC group(17.94-23.57 mg dL-1). Total VFA concentration were not affected by wilting nor by the type of concentrates (P > 0.05). Goats in the HCC group,however,numerically have higher total VFA concentration (178.5-183.75 mmol L-1) than those in the HPC group (142.21-174.64 mmol L-1). The apparent digestibility coeficients of DM, OM, CP and energy of the diet were not different (P > 0.05) when contained wilted or fresh Indigofera foliage. Significant increases (P < 0.05) in the DM and OM, but not in the CP and energy apparent digestibility coeficients were observed in the HPC goats. Dry matter intakes were not different (P > 0.05) among dietary treatments, but the ADG of goats in the HCC group (60-63 g d-1) were significantly lower (P < 0.05) than those of goats in the HPC treatment (80-87 g d-1). Blood glucosa concentration was not affected by wilting nor by type of concentrates (P > 0.05). BUN was not affected by wilting process, but providing high protein concentrates significantly (P < 0.05) increased the BUN concentration. It is concluded that foliage of Indigofera sp could be used as the sole forage in intensive production of goats. Wilting the foliage prior to feeding seemed to be unnecessary, since this process does not improve the animal productivity in term of daily gain and efficiency of feed utilization.

Plant morphology and physiology such as leaf area, total chlorophyll, and chlorophyll a/b ratio were affected by shading and fertilization. An experiment was conducted in Indonesian Research Institute for Animal Production (IRIAP) Ciawi, West Java. The objective of this study was to determine the morphology and physiology adaptation of three short grasses species for grazing namely Paspalum notatum, Brachiaria humidicola, Stenotaphrum secundatum on different shading and fertilization level. The experiment was arranged in split-split plot design. The main plot was shading level (0, 38, 56%); sub-plot was fertilizer dosage (0, 100, and 200 kg N/ha) while sub-sub plot was grass species. The results showed that leaf area were significantly different on different grass species, and there was interaction between shading and species on total leaf area. P. notatum on 38% shading level has the highest total leaf area (240.2 cm2). S. secundatum and P. notatum had a better adaptation in shading area compared to B. humidicola by increasing of total chlorophyll and decreasing of chlorophyll a/b ratio. Relative growth rate (RGR) of P. notatum and S. secundatum were increased by the increasing shading level. On the other hand relative growth rate of B. humidicola was decreased by the increasing shading level. Leaf area, chlorophyll content, and RGR were not significantly affected by fertilization dosage.

Alfalfa (Medicago sativa L.) is a herbaceus legume which is potential to be used as goat feed for it’s high production and nutritive value. This research was aimed to study the adaptation of alfalfa planted at highland-moderate climate and it’s utilization for goat feed. This research concists of two activities, ie 1) Agronomy of alfalfa that adapted to highland as a goat feed resource, and 2) The alfalfa usage technology as goat feed. On the first activity alfalfa was planted on highland-moderate climate Gurgur, Tobasa District, North Sumatra Province. Data was collected included: growth percentage, morphology and production aspects, and nutritive value. The harvesting was conducted for three times, where the first cutting had done at 100 days after planting. Investigation of morphology characterirtics was done before alfalfa harvesting. The utilization of alfalfa as goat feed was carried out on the second activity which was arranged in a completely randomized design. Twenty male Boer x Kacang crossbred (Boerka) goats of 5-6 months of age with average body weight 14.2±0.8 kg were randomly assigned to four feed treatments where each treatment consited of five replications. The four feed treatments were: P1 = 100% grass + 0% alfalfa; P2 = 90% grass + 10% alfalfa, P3 = 80% grass + 20% alfalfa, and P4 = 70% grass + 30% alfalfa. Data observation included dry matter intake, average daily gain, feed efficiency, and income over feed cost. Results showed that alfalfa growth percentage was 65% with good growth and high either production or nutritive value. The average shoot dry matter production was 438.6 g/m2 which was equivalent to 26.3 t/ha/yr. The crude protein content of alfalfa on the first, second and third harvesting were 17.93; 21.89 and 17.73 per cent, respectively. The utilization of alfalfa that had been processed to be crude-meal can be applied as goat feed. Supplementation of 70% grass and 30% alfalfa meal showed the best results: ADG 59.17 g/d, feed efficiency 0.14, and IOFC Rp 736/h/d. Key Words: Alfalfa, Herbage, Production, Meal, Feed, Goat

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

The cultivation of mulberry as forages is scarce in Indonesian feeding system for ruminant production, although many studies have indicated its nutritional potential as animal feed especially ruminants. This study was aimed to investigate the effects spacing of plant and cutting age on productivity and chemical composition of some species mulberry plants. The experiment was conducted in a randomized block design with factorial treatments. The factors species were (M. indica cv kanva, M. nigra, M. cathyana, and M. Multicaulis), the spacing of plants (1 x 0.5 m, 1 x 1 m and 1 x 1.5 m) and cutting ages (210, 240, and 270 days after planting). The results showed that species, M. multicaulis and M. cathyana are the highest growth, using a spacing of 1 x 0.5 m with cutting age 270 days after planting. Dry matter production highest (P 0,05) in M. Cathyana at spacing of 1 x 0.5 with cutting age 270 days after planting. The ratio of leaves and stems of plants are affected by age, the highest proportions of leaf is obtained at the cutting age of 210 days. Chemical composition were highest in M.multicaulis at the age of 270 days. The highest content of organic matter (OM) were found in M.Kanva and not different with M. Nigra at the age of 270 day after planting. In treatment of cutting ages have no effect (P 0.05) on the Crude protein (CP), ADF, NDF, lignin and tannin content. The average content of CP obtained gained 20.69%, 32.38% ADF, NDF 33.99%, 12.45% lignin and tannin 0.3%. Concluded that mulberry plants with a plant spacing of plant 1 x 0.5 and 270 days after plant have more advantages for use as animal feed.

The study was conducted in the Tinggi Raja village and Sumber Harapan Village of Sub district Tinggi Raja, in the Asahan District. Each location study has the same agro-ecosystems. The study was conducted using survey method in year of 2013 by interviewing 15 farmers respondent as cooperators and 15 non-cooperators. Primary data and secondary data were analyzed economically, using descriptive and quantitative tabulation. The purpose of this study was to determine the increase in business of goat breeders for economic analysis. The results showed that the net profit of the business of goats in cooperators breeders at the amount of Rp.8.411.168,83/year, B/C ratio of 1.4. Then for the non-cooperator farmers at the amount of Rp.1.644.051.24/year, B/C ratio of 1.2. This data showed that the benefit of farmer cooperators is higher than the non cooperator breeders. Therefore we need to implement the introduction of technological innovations for the farmer in non-cooperators breeders. For cooperators they could get into commercial business, that resulted in their goats achieving a higher market value in terms of price.
