| Abstract |
The present study was aimed to investigate the effect of dietary supplementation of different crushed Nigella Sativa seeds (NS) levels and two feeding regimes on some productive performance and physiological parameters in Mamourah laying hens. One hundred and five, 28 - weeks old, Mamourah hens were divided into five equal groups according to the following design: group A: received the control diet; group Band C:
received control diet plus 0.75% and 1.5 % crushed black seeds, respectively which given continuously for 12 weeks(28-40 wks). Whereas groups D and E received the same levels of NS seeds 0.75 and 1.5 %, but with an intermittent feeding 15:15 days system for the same period.
The results indicate that, finial body weight, body weight gain and egg weight were significantly (P<0.001) increased, but production efficiency, egg number, hen day percentage, egg mass (g / hen / day), economical efficiency percentage, feed intake (g / hen / day) and feed conversion were decreased by addition of 0.75% crushed NS seeds in continuous supplementation. However, inclusion of 1.5 % crushed NS seeds in the diet had no significant effect on final body weight, body weight gain and production efficiency in both continuous and intermittent feeding systems as compared with the control group. The addition of crushed NS seeds to the diet significantly (P<0.00l) reduced cholesterol and total lipids levels in serum and yolk. Shell weight and percentage, yolk index, Haugh Units score, and specific gravity were significantly (P<0.05) increased by dietary level of 0.75 crushed NS seeds in both continuous and intermittent feeding systems. However, dietary level of 1.5% crushed NS seeds had no effect as compared with control. Egg weight, yolk weight, yolk percentage, and yolk index were significantly (P<0.00l) increased, while Haugh Units score, albumen percentage, and shell thickness were significantly (P<0.00l) decreased with advancing production interval. Hen day percentage, feed intake, and egg mass (g / hen/ day) were significantly increased (P<0.00l). While the egg number increased (P<0.05) to reach the maximum during the period 32 -36 weeks of age and then decreased with advancing production interval. Concentration of cholesterol and total lipids in serum and yolk were significantly decreased by advancing of production intervals.
It could be concluded that addition of crushed NS seeds in layer diets may produce eggs with low cholesterol and total lipids content. These eggs may be more desirable for consumers, especially those suffering from heart disorders.
