A study was carried out to determine the effect of turmeric (Curcuma longa), ginger (Zingiber officinale), and garlic (Allium sativum) powder supplementations in feed on egg quality traits and intestinal microflora of small size local hens from 22-32 weeks age. A total of 180 Ac local hens at the 21 weeks of age were randomly distributed in a completely randomized design experiment, with 4 treatments and 15 replicates, each replicate consisted of a pen with 3 birds/pen. The experimental data was collected during 10 weeks. Treatments used: (1) Control (Cont): Basal diet (B) without any supplement in feed; (2) TUP: B + turmeric powder; (3) GIP: B+ ginger powder; (4) GAP: B + garlic powder, all supplemented at 0.5% in the diets.
The results showed that, average daily feed intake was not effect by turmeric, garlic and ginger supplementation in the diets (P>0.05).But, there was a little improvement hen day production (PSalmonella.spp; E. coli and Clostridium perfringens in the feces of Ac hens. In conclusion, turmeric and ginger powders supplemented in the diet at 0.5% improved the egg production and yellow color of egg yolk of Ac hens to compare with that of garlic and control groups. However, the highest egg weight was found in garlic treatment. And supplementation of turmeric, ginger and garlic reduced Salmonella.spp;E. coli and Clostridium perfringens in the feces of Ac hens.
