| Summary, etc. | The present study aimed to investigate the impact of probiotic as commercial growth promoter and either fenugreek or black seed as natural growth promoter at levels of 0.05, 0.1 and 0.15% in practical laying diets on productive performance and economical efficiency during 40-59 weeks of age. A total number of 240 Hy-Line White laying hens were distributed into 10 equal groups , each of 24 birds in four replicates .The first group received the basal diet without any supplementation, whereas the other groups were given the basal diet supplemented with either probiotic, fenugreek or black seed each at levels of 0.05 , 0.1 and 0.15% . The results obtained could be summarized as follows: 1- The highest body weight at 59 weeks of age was obtained from 0.05% inclusion level of each of probiotic, fenugreek and black seed. However, fenugreek treatment was significantly surpassed over all dietary treatments. 2- The inclusion level of either 0.1% probiotic,0.05 and 0.15% fenugreek or 0.1and 0.15% black seed significantly gave higher egg production than those of control group. However, fenugreek and black seed were insignificantly superior than the probiotic group. 3- Inclusion levels of probiotic, 0.05% fenugreek or 0.05 and 0.15% of black seed significantly increased egg weight. Moreover, egg mass was significantly increased with all studied levels of probiotic, black seed and 0.05% and 0.15% fenugreek . 4- There were no significant differences in feed consumption among all dietary treatments including the control group. While, feed conversion was significantly (P<0.05) improved at levels of 0.1, 0.05 and 0.15% for probiotic, fenugreek and black seed, respectively. 5- There were insignificant increase (P<0.05) in egg shape index (SI), yolk index (YI) and shell thickness (ST) and significant effect on Haugh units (HU) for all treatments. Furthermore, probiotic at 0.1% level, fenugreek at 0.15% and black seed at all levels had significant increase on yolk color (YC). 6- Probiotic, fenugreek and black seed inclusion had significant effects (p<0.05) in decreasing yolk total cholesterol compared with the control group and had no significant effect on total lipids of egg yolk. 7- Either probiotic, fenugreek or black seed had no positive effect on unsaturated fatty acids of egg yolk oppositely, they had positive effect on some saturated fatty acids like Palmitic acid (c16:0) . 8- Economic evaluation for egg production was improved by using all dietary treatments. However, the best value was achieved by using 0.05% fenugreek, 0.15% black seed and 0.1% probiotic . |
