Abstract

|
Body weight gain in the niadn deficient group of quail was markedly lowered as compared to that of the control group, but heart, kidney and liver weight were slighdy reduced reladve to the body weight. Nicotinic acid deficiency resulted in the significant increase of serum glucose level but the serum cholesterol, albumin and total protein levels were not affected to any extent. Glutamic oxaloacetate iransaminase and glutamic pyruvate transaminase activities were significandy enhanced but alkaline phosphatase and lactic dehydrogenase activities were not influenced. Tryptophan and tyrosine levels were remarkably reduced and a similar observation was also made with aspartic acid, glutamic acid and alanine plus serine. However, the levels of basic amino acids such as arginine, histidine and lysine plus branched chain amino acids such as isoleucine, leucine and valine were not affected.
