Enhancement of the feeding value of wheat offal for broiler feeding after its solid state fermentation with Aspergillus niger

Abstract

The objective of this study was to investigate the changes in in vitro dry matter digestibility (IVDMD) of wheat offal (WTO) after its biodegradation with Aspergillus niger and also to determine the effect of degraded WTO on the performance parameters of broiler birds at starter and finisher phases. A. niger was used for the biodegradation of WTO. There were five dietary treatments of 33 birds each. Having degraded the WTO, it was observed that there was improvement in crude protein value from 2.43 g/100 gDM to 4.00 g/100 gDM (39.25% improvement). The crude fibre had 28.02% reduction after the degradation. At the starter phase, body weight gain was significantly (P<0.05) higher in the birds fed degraded wheat offal (DWTO). At the finisher phase, feed conversion ratio was significantly (P>0.05) lower in birds placed on DWTO. The relative cost benefit (RCB) showed that economically, the birds placed on DWTO gave better profit margin than the ones placed on the undegraded wheat offal (UWTO). The results revealed that A. niger was able to enhance better availability of energy, crude protein and other nutrients which were hitherto encapsulated in the undegraded WTO.

Performance of broiler chickens fed wheat offal and maize based diets

“…The study was also in agreement with the study of Yusuf (2020) that replacement of maize in broiler chickens feed with 15% wheat offal increased the growth performance and organ yield of broiler chickens. The wheat offal increased the crude protein content of the broiler feed with enzyme supplement after fermentation by Aspergillus niger and this could increase the growth rate and body weight of the birds (Lawal et al, 2012). The effect of given broiler chicken wheat offal was statistically significant on the body weight gain compared with the broiler chickens fed maize feed in which the calculated value of t-test was 4.818 and table value of t-test was 3.497 at α ≤ 0.005.…”

“…This could be an indication that dietary fibre components of Soybean chaff, being plant protein origin, is more soluble and hydrolysable by endogenous enzyme to release more amino acids precursors or substrates needed for muscle protein synthesis compared to non-starch polysaccharides (NSP) fractions in wheat offal. Lawal et al (2012) had reported that plant cell wall contains a variety of polysaccharides which are interlinked with each other by covalent or non-covalent linkages, thus their efficient utilization as dietary fibre sources in poultry diets depend on the efficacy of its conversion into respective peptides or amino acids, oligo or monosaccharide. stick) indicates that the dietary treatment is adequate for maintaining broiler meat production.…”

Effect of Aspergillus niger and Trichoderma viride on the Nutritional Composition of Alkali Pretreated Groundnut Husk

“…The improvement seen in the available minerals may be explained by the ability of the organisms to elicit phytase which increases the availability of phosphorus and this may invariably lead to improvement in the availability of other minerals such as zinc, manganese, calcium, copper and iron that are susceptible to chelation with phytate [20].…”
