| Abstract |
A total number of 150 unsexed 7day old Hubbard chicks were distributed into five experimental treatments. Each of 30 chicks in 3 replicates (10 chicks I replicate) was used in this study. The first experimental group was fed on the control diet, whereas, groups 2, 3,4 and 5 were fed on control diet supplemented with Tafla (local clay) at a level of 1.5,3,4.5, and 6% .A starter diet was used during the starter period (7-28 days of age) contained 22.03 % CP and 3105 kcal ME /kg diet, while the finisher diet contained 19.00 % CP and 3196 kcal ME /kg diet was used during the finisher period (29-49 days of age) , all the nutrients were as recommended by NRC (1994). Diets were nutritionally evaluated through growth performance feed intake and feed conversion as well as percentage of dressing, digestibility trials and blood parameters.
Results obtained could be summarized as follows:
1. Average live body weight and body weight gain were significantly (P<0.01) increased in broiler groups fed on the diets supplemented with 3% Tafla compared with other group.
2. Values of feed conversion were significantly improved, while average feed consumption was decreased significantly with Tafla supplementation 1.5% level.
3. Digestibility coefficients of DM, OM CP, EE, CF and NFE were significantly (P<0.01) increased with Tafla supplementation at levels 1.5 and 3%.
4. Relative weights of total edible parts were significantly affected by Tafla supplementation.
In general, these results indicate that using 1.5 and 3% Tafla as feed additives enhancement the productive performance and economical efficiency with no adverse effects on blood constituents of broiler chicks.
Key words: Clay, Tafla, broiler, diets, productive performance.
