A study was carried out to find out the effect of supplementing different levels of linseed oil in the laying hens’ diet on egg white quality, yolk index and economics of feeding, during a period of 16 weeks. One hundred forty White Leghorn layers were randomly allocated into seven experimental groups having 5 replications of 4 birds in each and sited in individual cages from 22 to 38 weeks of age. The laying hens of control group (T1) were fed a basal diet formulated as per BIS (2007) standards. The layers of treatment groups T2, T3, T4, T5, T6 and T7 were fed basal diet supplemented with linseed oil at levels of 1, 2, 2.5, 3, 3.5 and 4%, respectively. The results of the study depicted that the result findings depicted that with respect to the whole period there was no significant increase in the yolk index percent by inclusion of different levels of linseed oil in either of the dietary treatments in the basal ration of hens. Albumin index values were significantly (P<0.05) higher in hens of treatment group T4 (2.5% Linseed oil), T5 (3% linseed oil), T6 (3.5% linseed oil) and T7 (4% linseed oil) as compared to the control and other lower dietary supplemental (T2 and T3) treatment groups. Whereas, no significant difference was observed among T1, T2 and T3. Haugh unit’s result reveal that during the whole period of experiment, hens in treatment groups T4 and T7 show significant (P<0.05) difference as compared to the control T2, and T5 experimental groups. Feed cost value for per kg egg mass production decrease in treatment groups T4 (2.5% linseed oil), with a reduction in cost per kg of egg mass production for Rs. 5.17 in treatment groups T4 (2.5% linseed oil) in comparison to T1 (non-supplemented maize based control diet). Thus we can conclude from this study that linseed oil supplementation significantly increase albumin index and Haugh unit but decrease in feed cost per kg egg mass production no effect on yolk index. However no significant results were found in case of yolk index.
