Abstract

This study, laid out in a 2 x 4 factorial arrangement compared egg lipid profile of egg-type chickens on two housing types (battery cage and litter-covered floor) and on extract of oyster mushroom (0, 10, 20 and 30 ml/L of water) at early and late lay phases. Each treatment consisted of 30 birds sub-divided into three replicates of ten birds each. Data obtained were subjected to analysis of variance. Results showed that birds in the battery cages recorded a higher (P ≤ 0.05) deep yellowish yolk colour and higher (P ≤ 0.05) triglycerides (1427 g/dl), and very low-density lipoprotein, VLDL, (285.40 g/dl) compared to those housed on litter-covered floor at early lay. In the extract of oyster mushroom (Pleurotus ostreatus), eggs from birds on 20 ml/L of water had the lowest (P ≤ 0.05) triglyceride (1362 g/dl) and VLDL (272.40 g/dl) in early lay. At late lay, higher eggshell thickness of 0.39 mm was obtained in eggs from birds on the litter-covered floors. In the interaction between housing types and extract of oyster mushroom, significantly (P ≤ 0.05) highest eggshell thickness (0.45 mm) was obtained in eggs from birds on litter-covered floors and on 10 ml/L extract of oyster mushroom. However, housing types and extract of oyster mushrooms did not significantly affect (P > 0.05) lipid profile of eggs at late lay. Housing types and extract of oyster mushroom neither increased nor decreased cholesterol contents of the eggs at both early and late lays.
