Gross efficiency of protein and metabolisable energy utilization of sugarcane press residue incorporated in layer diets

Abstract

Sugarcane press residue (SPR), a nonconventional feed ingredient is a soft, spongy, amorphous, dark brown to white material was fed to 32-week-old white-leghorn-layer at 0, 5, 10 and 15 per cent either in the soya-based or fish-based diets to form T1 to T8 diets, respectively. Each diet so formulated was offered to five-replicates of four laying-hens each constituting a total of one-sixty birds reared for 84-days. Results revealed that the cumulative efficiency of protein utilization values of layers fed different experimental diets were 29.36, 28.62, 27.20, 29.11, 27.90, 28.21, 28.02 and 25.95 in T1 through T8 groups, respectively. Likewise, efficiency of energy utilization values ranged non-significantly from 28.18 (T1) to 24.84 (T8). Whereas, average EPU and EEU values due to main factors were found to be statistically non-significant. It was concluded that SPR can be included up to 15% in soya and fish based layer diets for energy and protein utilization apart from inorganic-matter.
