Abstract

the aim of present study was investigat the effect of Purslane powder on cecal microbial population, blood parameters and tibia characteristics of laying hens. One hundred and twenty Leghorn Hy-Line (W36) strain in 44 to 52 weeks of age used in a completely randomized design with 4 treatments and 5 replicates to receive diet supplemented with 0 (control), 1, 2 and 3 % of dried purslane. The results showed that Purslane powdered supplementation was significantly reduced E.coli and coliform bacteria (P<0.05). Lactobacillus bacteria population affected by the experimental treatments were significantly higher than controls (P<0.05). Use purslane powder of different levels to diet had no significant effect on blood cholesterol and triglyceride concentrations (P>0.05) but significantly decreased of glucose (P<0.05). These experiments showed that the addition of purslane powder in the diet of laying hens had no significant effect on the weight of bone, epiphysis diameter, outside diameter, inside diameter and thickness of the tibia (P>0.05). Volume weight, dry weight and tibia ash were significantly affected by the experimental treatments (P<0.05). The results showed that the purslane powder had positive effects on cecal microbial populations have and led to better tibia bone mineralization in caged laying hens.
