Abstract
The objective of this work was to evaluate the response of broiler chicks to different types and mixtures of-spices as growth promoters. Three feeding trials were conducted in which black or hot pepper, canella, and carnation were fed at 0.2% individually (Trial 1), or as a mixture (Trials 2 and 3) and compared to spices free diet and antibiotic (Neomycin) supplemented-diet. Growth of Broilers, feed intake and feed conversion ratio (FCR) as well as percentage of dressing and internal organs were the studies traits. Moreover, in trial 4, the digestibility of protein and fat as affected by Neomycin and different types as well as mixtures of spices was determined. Results could be summarized as' fellows~ 1- Results frerr» trial' 1 iJiTl!ti~ tInat" €ll~ Qf I1l.ladt Ijl.eIjlPeJi ir.lsipfi"c:aza1J¥ improved gmw!1ili by 2..2.%. 11IiT.eaJi1WlitJle FCR was ilililf1l:cmeall si![mif€aJlltllW lilY' u_3Jll1D wmen oo~di t~ tlire commH did..

They showed similar growth and FCR to Neomycin supplemented-diet. 3- It was concluded from trial 3 that, a mixture of either black pepper or hot pepper with canella, and carnation significantly improved growth by 3.9 and 4.2% as well as FCR by 6.7 and 6.7%, respectively as compared to the control group. They also exhibited signifcantiy better growth than Neomycin supplemented-diet, even though FCR was not significantly different. 4- The significant improvement in fCR of Neomycin, and spices supplemented-diets occurred mainly during 6-21 d of age, and lessen thereafter, and this correlated with the significant reduction in feed intake of broilers during this period. 5- Comparing results from trials, 2 and 3 indicated a synergistic effect of canella when added over black pepper and carnation as well as carnation when added over hot pepper, and canella on growth by 10.3 and 5.5%, and FCR by 5.6 and 4.7, respectively. 6- In general, the results from trials 1, 2, and 3 indicated that 0.2% black pepper improved growth insignificantly, and FCR significantly as compared to the control diet, and being equal potent as any mixture of spices as well as Neomycin. 7 - There were insignificant differences in efficiency of the protein, or fat retention among different types or mixtures of spices and the control 'group as well Neomycin in trial 4, however, numerical improvements were observed. 8- In general, Neomycin and different types and mixtures of spices had no adverse effects on dressing and internal organs of broilers. it is concluded that 0.20% of black pepper could serve as non conventional feed additive in broilers diets, however, further research for alternative feed additives should be continued.
