Abstract: This study was carried out to evaluate the effect of dried ginger (Zingiber officinale) root powder (DGRP), as natural anti-bacterial on productive, reproductive and physiological performance of Mandara developed local strain hens. A total number of 240 laying hens and 24 cocks from Mandara strain at 24 weeks of age were assigned equally to four experimental groups of 3 replicates each, Birds in groups 1 (control, B') and 3 (B+) fed on basal diet, while birds in groups 2 (G-) and 4 (G+) fed on ginger diet (GD) with 1% dried ginger root powder (DGRP) as replacement from corn. Birds of groups 3 and 4 (B+ and G+) were orally treated with 1 ml S. enteritidis broth culture/hen (+) at 24 weeks of age, While birds in groups 1 and 2 (B- and G-) not treated by S. enteritidis (-). The basal diet was formulated to be 16% CP and 2700 Kcal ME/Kg diet according to Agriculture Ministry Decree (1996). The experimental work extended for 12 weeks and the feed consumption, live body weight. egg production parameters, fertility and hatchability % were recorded every 4 weeks, while the egg quality parameter. plasma analysis. some liver and egg yolk analysis, colonization of S. enteritidis on some organs were recorded at the end of the experiment. Also, the immune response of birds against New Castle disease (ND) was measured, and the economic efficiency of using DGRP level 1 % was calculated at the end of the experiment.
The overall results showed that, infection with S. enteritidis depressed the recorded values of all studied criteria of Mandara laying hens, but feeding hens on diet containing 1 % dried ginger could moderate the deleterious effects of S Enteritidis, Also, feeding on diet containing 1 % dried ginger improved values of egg number, egg weight, egg mass, feed conversion ratio, fertility and hatchability and most of egg quality parameters comparing with other groups. Although, using diet contained 1% OGRP did not change yolk lipid contents, yolk and liver total cholesterol, the determined values of plasma total cholesterol were decreased than that recorded for un-supplemented basal diet group,
Adding 1 % DGRP to the diet of treated Mandara laying hens with S enteritidis decreased the colonization of S enteritidis on internal body organs especially spleen and intestine. On the other hand, S.enteritidis infection reduced the immune response of hens against ND. Economically, DGRP decreased the feeding cost/dozen egg by 5.21 % compared with that of B- group.
So, it could conclude that adding 1% DGRP to diet of Mandara laying hens could enhance their productive, reproductive and immunological performance especially in case of S. enteritidis infection.
