Addition of Aspergillus Niger Palm Waste (Animal Feed Alternative)

Abstract

The study aimed to determine the effect of adding the fungus Aspergillus niger to the chemical quality of fermented palm oil leaf and midrib waste as an alternative feed ingredient. The research design used a Completely Randomized Design (CRD) in one direction with four treatments and four replications. The treatment given to oil palm leaves and midribs was P0 = oil palm leaves and midribs + 20% EM4, P1 = oil palm leaves and midribs + 20% EM4 + 1% Aspergillus niger, P2 = oil palm leaves and midribs + 20% EM4 + 2% Aspergillus niger, P3 = oil palm leaf and midrib + 20% EM4 + 3% Aspergillus niger. This fermentation was carried out using the Least Significant Difference Test (SDT) method. The results showed that the fermentation of oil palm leaves and midribs could significantly increase the crude protein content in the P2 treatment (10.32%) and organic matter in the P1 treatment (29.09%), but had no significant effect on dry matter and crude fiber.

Pre-Treatments of Sonneratia Alba Fruit as The Potential Feed for Ruminant Using Aspergillus Niger at Different Fermentation Times: Tannin Concentration, Enzyme Activity and Total Colonies

“…Ikhlas et al (2023) stated that the use of lime water with a concentration of 5% for 10 minutes can reduce tannins up to 4.54%. Fermentation is a technology to improve the quality of animal feed using microorganisms (Ciptaan et al 2022;Syamsuddin et al 2022). Mold is the most commonly used microorganism for tannase production (tannin acyl hydrolase).…”
