The study aimed to investigate the effects of offering different levels of ensiledÂ or fresh Indigofera arrecta in completete diets on the feed consumption, ADG, ruminal fermentation characteristics and blood metabolites concentrations in growing goats. The I. arrecta/concentrate ratios of the complete diets were set at 85/100,75/100 and 65/100. Thirty weaned-male goats were used in the study, and were randomly allocated to one of the six treatments (5 heads per treatment). The diets were offered at 4% BW and the animals were weighed weekly. The study was arrangedÂ as a completed randomized design. Feed intake, average daily gain, feed efficiecy ratio, ruminal fermentation (pH, NH3 and VFA characteristics and blod metabolites (glucose and urea) were analysed. Feed intake of goats receiving ensiled Indigofera arrecta were lower (P < 0.01) compared to those receiving fresh I. arrecta. ADG were higher (P > 0.01) when goats were fed diets with lower level inclusion of Indigofera arrecta. Efficiency of feed utilization decreased (P < 0.01) when ensiled Indigofera arrecta was used in the diets, but it was not affected (P > 0.01) by the inclusion level of I. arrecta in the diets. Ruminal pH was not affected by ensiling process, but ruminal NH3 concentrations were greater (P < 0.01) in goats receiving fresh Indigofera arrecta. Ruminal VFA levels were also greater (P < 0.05) in the group offered fresh Indigofera arrecta, but the differences were not significant (P > 0.05) when diets consisted of 65% Indigofera arrecta in the complete diets. IncreasedÂ rate of Indigofera arrecta inclusion in the diets resulted in lower (P < 0.01) counts of ruminal microbial population. The concentration of plasma urea nitrogen were neither affected by the ensiling process nor by the levels of I. arrecta inclusion in the diet (P > 0.05), however, the plasma glucose level decreased (P < 0.05) as the level of I. arrecta inclusion in diets increased. It is concluded that I. arrecta could be used as the sole fresh or ensiled foliage in complete diets, although the performances of goats were better whenÂ fresh I. arrecta was offered. The level of I. arrecta inclusion in complete diets was recommended at not greater than 65%. Key Words: I. arrecta, Silage, Complete Feed, Goat

Nutritional Support for Small Ruminant Development Based on Oil Palm By-products simon petrus ginting; K Simanihuruk; A Tarigan; K R Pond

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.
