Abstract :
The response of Brown laying hens to palmitic,stearic,oleic and linoleic acids was investigated.Five experimental diets were obtained by supplying the above fatty acids up to 30 g kg -1 each to an inadequate protein and sulphur amino acid (SAA) diet. Each diet was fed to 24 individual hens from 39 to 50 weeks of age.Only supplemental palmitic acid increased egg production and egg output significantly.Egg weight was increased by added linoleic acid significantly.Supplemental palmitic acid improved the efficiency of protein,SAA and energy utilization.
