Abstract
The present investigation was performed to examine the changes in body weight, feed efficiency ratio (FER), organs development and some blood parameters in albino rats received daily ingestion of lower levels of two food additives: egg yolk (EY) and egg white (EW) at two levels (5% and 10%) for 30 days (malnutrition phase) followed by daily ingestion of balanced levels of 15% EY or EW (refeeding phase) for other 30days.
Results showed that lower levels of EY or EW reduced the final body weight, daily feed intake and FER during malnutrition. In spite of refeeding, these rats with diets of 15% EY or EW for 30 days still had lower weight and they did not quite reach control value. The diet of 10% EW enriched with 5% cholesterol reduced the FER. The weights of organs: liver, kidneys, spleen, heart, testes were reduced in both phases as compared to control (15% casein). Blood hematological parameters showed reduction in HB conc. during malnutrition .In refeeding phase, rats fed on diet of EY 15%, the counts of RBCs (10.6× 106) exceeded the control (8.8 × 106). Reduction in WBCs counts was observed in blood of rats fed on EW 5%. Packed cell volume (PCV) ranged between 31.3-40.1% in malnutrition and 38.9 – 45.1% in refeeding phase. Other parameters as mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH) and mean corpuscular hemoglobin concentration (MCHC) showed indefinite trend in the present study.
