Effects of dietary levels of sun-dried sheep manure on productive performance and egg quality parameters of Shika-brown layers

An experiment was conducted to test the effect of dietary levels sun-dried sheep manure (SSM) on egg quality parameters and productive performance Shika-Brown layers. Six isonitrogenous almost isocaloric diets were formulated contain SSM at 0.0, 1.0, 2.0, 3.0, 4.0 5.0 % level inclusion. Diet I, which had no manure, served as control. White maize used for formulation diets. Each six replicated four times with five birds per replicate in a completely randomised design experiment. The housed singly cages. laying hens first maintained control diet contained very little or yolk pigmenting factor depigmentation period twenty-one days. During this period, samples eggs broken out colour scores determined using Roche Yolk Colour Fan (RYCF). By twenty-first day, (RYCF) dropped lowest value one. then placed experimental study, covered twelve weeks. Parameters measured included colour, Haugh unit value, index shell thickness. For characteristics, percent hen day production, peak feed intake, conversion efficiency (kg feed/12 eggs) cost /2 produced. Results obtained indicate that significant (P<0.05) RYCF intake but (P>0.05) other such weight, unit, index, thickness, shell, efficiency, (N/12 eggs), production.
