Abstract

This study was conducted to investigate the effects of dietary feed regimes (FR) and microorganism strain (MS) on egg quality traits, semen quality, fertility and hatchability per total or fertile eggs as well as economic efficiency of Inshas hens (Egyptian local developed strain) during laying period. A total number of 240 laying pullets + 24 cockerals, 24 weeks old were randomly taken to be similar in body weights (1463.15±5.57), which were randomly divided into eight experimental groups, (30 pullets + 3 cockerals in each). Each group was contained three replicates (10 pullets +1 cockeral in each). The experimental groups involved a 2x4 factorial arrangement, 2 diet groups feed regimes ( ad -libitum, mash diets and restricted mash diets (110g diet/bird/day) and 4 microorganism Bacillus strains as feed additives, which were  0.5 % Bacillus subtilus (109CFU/gm),  0.5 % Bacillus licheniformis (109CFU/gm) and 0.5 % Bacillus amyloliquefaciens (109CFU/gm)), respectively, during the experimental period lasted four month from 24 to 40 weeks of age. The obtained results showed that feeding regimes in laying hens' significantly (P<0.05 and P<0.01) caused to improve in Haugh unite and shell weight percentage and fertility percentage and significantly (P<0.01) decrease of albumin index when compared to ad libitum group. While, egg weight, shape index, sell thickens, yolk index, yolk weight %, albumen weight % and hatchability of egg set and fertile eggs % were not significant effected. However, the effect of differences between FR show at 110g diet/bird/day an increase of net revenue (NR) and economic efficiency than the fed ad libitum. Concerning effect of microorganism Bacillus strains supplementation in layer diets caused to increase improved (P≤0.01) significantly of yolk index, Haugh units, yolk weight and albumen weight percentages, sperm motility, dead spermatozoa, sperm abnormalities, sperm cell concentration and fertility values when compared to control group. However, the effect of MS supplementation showed the best of (EEF) when treated with B.subtilus. The interaction effects between FR and MS supplementation were significant (P≤0.05) and (P≤0.01) in egg shape index, albumen index and albumen weight and shell weight percentage percentages were significantly (P<0.05) while, semen quality fertility and hatchability per total or fertile eggs values were insignificantly effect. The higher average of relative EEf (41.52, %) was found in the interaction between 110g dietary consumed and dietary supplementation B. subtilus, whereas, the lower one (14.00%) was shown in the interaction between add- libitum dietary consumed without any additives,  Conclusively, it can be concluded that, feeding layer diets at 110g with supplementation MS at level 0.5% were more effective for improving of yolk index, Haugh units, albumen index, shell weight (%), semen quality, fertility and hatchability per total or fertile eggs values as well as recorded the highest (EEF) when compared to other treatment groups of Inshas laying hens.
