This experiment was conducted to study the effect of different dietary n-6: n-3 fatty acid (FA) ratio on performance, egg quality, some blood and reproductive parameters of Japanese quails breeder. A total of 720 Japanese quails (Coturnix coturnix japonica) were used in a completely randomized design with five treatments, six replicates and 24 birds (16 females and eight males) in each replicate. Dietary treatments were control (n- 6: n-3 FA ratio were 13:1) and different n-6: n-3 FA ratios (1:1, 3:1, 6:1 and 9:1). The results showed that, quails fed diet with n-6: n-3 FA ratio of 1:1 had the highest feed intake in comparison with the others (P <0.05). Egg mass of quail was increased significantly when their diets containing n-6: n-3 FA ratio of 6:1, in comparison with 9:1 and control (P <0.05). The birds fed diets containing n-6: n-3 FA ratio of 1:1 and 6:1 had higher eggs Haugh unit rather than control (P <0.05). Feeding quails with diets containing n-6: n-3 FA ratio of 1:1 to 9:1 reduced serum triglyceride concentration compared to the control group. Blood cholesterol concentration of birds that fed diets containing n-6: n-3 FA ratio of 1:1 and 6:1 was lower than control and blood glucose was the highest in the birds that fed diets containing n-6: n-3 FA ratio of 1:1 (P <0.05). The results of this experiment showed that the use of dietary n-6: n-3 FA ratio of 6:1 in breeder quail diets can improves production performance.

Two experiments were conducted to evaluate the nutritional value of Purslane powder and its effects on performance, egg quality and reproductive system parameters of laying hens. One hundred and twenty laying hens (Leghorn, Hy-Line W-36) were used in a completely randomized design with four treatments and five replicates. Hens received diet supplemented with different levels of Purslane powder (0, 1, 2 and 3 percent) for 8 weeks. The results of these expriments showed that gross energy, crude protein, ether extract and crude fiber contents of Purslane samples were 2921.67 (Kcal/Kg DM), 22.28 (percent), 3.99 (percent) and 9.47 (percent) of DM, respectively. The AME and TME values of Purslane powder were 1864.70 and 1956.08 Kcal/Kg DM, respectively. Performance parameters of the laying hens were not affected by inclusion different levels of dietary Purslane powder in the diet. Shell strength, shell thickness, egg yolk color, ovary and oviduct weights, the number of large yellow follicles and the weight of largest follicle showed significant increase (P< 0.05) in treatments containing Purslane as compared to control group. According results of this experiment, use of Purslane powder in laying hens diet can improve quantitative traits of eggs and reproductive parameters. Therefore, Purslane powder can be used in the diets of laying hens at three percent.
