Egg Laying Performance and Blood Chemistry of Birds Fed Fermented and Unfermented African Locust Beans Based Diets
Journal Title: Journal of Animal Production Advances - Year 2015, Vol 5, Issue 12
Abstract
The study was carried out to compare the effects of unfermented and fermented African locust beans on performance and blood chemistry of laying hens in the unfermented African locust beans (UALB), the seeds were dehulled prior to boiling in water. The fermented African locust beans (FALB) contained seeds that were dehulled and boiled in water prior to natural fermentation for 4 days. One hundred 40- week old laying hens (Nera black) were randomly assigned to five dietary treatments in which UALB and FALB replaced soybean meal at 50% and 100% levels respectively. Higher residual amounts of tannin and phytate were obtained in the UALB. Egg weight and hen day production were conspicuously (P<0.05) reduced in birds fed 100% UALB. The hemoglobin, packed cell volume, red blood cells and white blood cells were significantly (P<0.05) reduced in hens fed 100% UALB. The serum enzymes, alanine transaminase, aspartate transaminase and alkaline phosphatase were significantly (P<0.05) increased in the birds fed 50% UALB and 100% UALB respectively. Marginal differences were however obtained in all the response indices between hens fed the control diet, 50% FALB and 100% FALB respectively. It is therefore concluded that fermentation is a better processing method for optimal utilization of Africa locust beans in diets of laying hens.
