Optimization of the utilization of blood meal with palm oil fronds absorbance fermented as feed stuff to changes of nutrition content

Abstract

The utilization of agricultural and livestock waste by-products, apart from being an alternative feed ingredient, can also reduce environmental pollution. Palm fronds as a by-product of oil palm plantations are rarely utilized and most of them will be burned and couraging climate change phenomenon. Cattle blood is a by-product of abattoirs that directly impact the environment. Most of the cattle blood not used efficiently, and pollutes the environment. The research aims to increase the use of blood meal with the absorbance of palm fronds fermented as feedstuff on changes in nutritional content. The study used a completely randomized design with a factorial pattern. Factor A is the inoculant treatment, namely A1: Bacillus amylolytic flavacient bacteria A2: Lactobacillus plantarum bacteria, factor B is the incubation time, namely: B1 = 0 hours; B2 = 60 hours and B3 = 120 hours., each treatment was repeated 3 times respectively. Parameters observed were nutrient content based on proximate analysis The results showed that there was interaction between the type of inoculant and the incubation time used in fermenting blood meal with the absorbance of palm fronds. Incubation time had a significant effect (P<0.05) on the content of dry matter, organic matter, crude fiber and crude protein, while the incubation time had no significant effect on (P>0.05) crude fat content. Based on the results of the study, it was found that in blood meal with absorbent palm oil fronds, Lactobacillus plantarum inoculants with an incubation times of 120 days gave the best results in blood meal with absorbance palm oil fronds fermented.
