Abstract
Abstract | Fermentation palm oil waste that can break down fiber content, supplementation of cassava leaves silage and addition of organic micro minerals are also efforts to increase the nutritional content that it can meet the needs of animal feed. The effect of fermented palm oil fronds, supplementation of cassava leaves and organic micro minerals on growth and digestibility nutrients of goat. This study used 12 Ettawa Grade goats, used a Randomized Block Design (RBD) method which was and based on body weight. Feed materials used in this study were fermented palm oil waste (palm fronds and fronds), cassava leaves silage, and organic micro minerals. The treatments consisted of R1: control ration; R2: ration waste based on fermented palm oil; R3: R2 + cassava leaves silage; and R4: R3 + organic micro minerals. Supplementation of cassava leaves silage and organic micro minerals in palm oil waste based rations significantly affected (P 0.1) on crude fiber digestibility, digestibility of crude protein, crude fat digestibility, and TDN in goats. Supplementation of cassava leaves silage and organic micro minerals in palm oil waste based rations with different treatment on goats had improved on body weight gain and feed efficiency but not affect on digestibility of crude fiber, crude protein, crude fat, and TDN in goats.

Highlights
The main feed of goats are forage, forage is a good source of energy and vitamins, but the crude protein content is relatively low compared to grain feed
Efforts to improve ruminant animal feed based on palm oil waste that are considered quite effective are by conducting fermentation technology
Data obtained from the results of the study were analyzed using analysis of variance (ANOVA) and the least significant difference test (LSD) would be carried out if the ANOVA was significant (Steel and Torrie, 1991)
Summary
The main feed of goats are forage, forage is a good source of energy and vitamins, but the crude protein content is relatively low compared to grain feed. Utilization of plantation industrial waste is an alternative that needs to be done so that it can meet the needs of animal feed with high nutrient content and digestibility. Efforts to improve ruminant animal feed based on palm oil waste that are considered quite effective are by conducting fermentation technology. This fermentation technology can increase the structural digestibility of carbohydrates and increase the amount of protein by chemical, physical, and biological fermentation. Supplementation of cassava leaves silage and addition of organic micro minerals are efforts to increase the nutritional content of the ration and the digestibility of the ration so that it can affect production (Muhtarudin et al, 2016, 2018)
