HYPOCHOLESTEROLEMIC EFFECT OF THE ANOXYGENIC PHOTOTROPHIC BACTERIUM RHOPSEUDOMONAS PALUSTRIS MGU001 IN HEN LAYING EGGS.

ABSTRACT: The study was designed to investigate the effects of dietary Rhodopseudomonas palustris on the laying hen. The values were recorded after about a period of 60 days. Dietary supplementation of four day old cultures of R.palustris at 0.08 % reduced cholesterol and triglycerides concentration in serum by 15.34 % and 6.19 % respectively. The hen egg-yolk recorded a reduction of about 17.18 % in cholesterol concentration. Also, supplementation of R.palustris in diets increased high-density lipoprotein cholesterol level and decreased atherogenic index in serum. Reduction in the levels of cholesterol was also observed in liver, breast and thigh muscles. Diets fed with R.palustris may lead to the development of chicken and eggs containing less cholesterol. Significance of the above results with respect to the existing literature are discussed in this communication
