Evaluation of Nutrient Digestibility of Goats Fed on Biofermented Cocoa Pods Using Phanerochaete chrysosporium Supplemented by Mangan (Mn) and Calsium (Ca)

Abstract

An in vivo experiment was conducted to evaluate biofermented cocoa pods to substitute forages for goats. The experiment was carried out using a Randomized Block Design on a total of 15 goats with 5 treatments and 3 blocks. Ration wasRation was designed iso-protein (50 g/day) and TDN (359 g/day) using cocoa pod (CP) or napier grass (NG) as forages and concentrate. The treatments consisted of concentrate plus : 80% NG (R1); 60% EG (R2); 30% EG and 30% untreated CP (R3); 30% EG and 30% bio fermented CP supplemented Mn and Ca (R4), and 30% NG and 50% biofermented CP supplemented Mn and Ca (R5). Variables measured were feed consumption, nutrient digestibility and average daily gain. Data were analyzed. Data were analyzed with analysis of variance and followed by Duncan`s multiple range test. Results showed that ration contained 30% biofermented CP supplemented by 100 ppm Mnbiofermented CP supplemented by 100 ppm MnCP supplemented by 100 ppm MnMn and 1 190 ppm Ca, 30% napier grass and 40% concentrate 40% concentrate resulted in a better goat performance and more profitable than other rations. Goats receiving such ration had more advantage on dry matter consumption (560.33 g/day/head), dry matter digestibility (70.48%), organic matter digestibility (74.31%), feed conversion (5.50), average daily gain (101.79 g/day/head) and income over feed cost (Rp 1 192.80) compared to the other treatments. It was concluded that cocoa pod biofermented with Phanerochaete chrysosporium supplemented by Mangan ( 100 ppm Mn) and Calsium (1 190 ppm Ca) is potential to be used as forages for substituting napier grass for feeding goats during growing period.
