This study aims to utilise thyme oil (TO) as a natural growth promoter in comparison to mannanoligosaccharides (MOS) for broilers raised under hot climates from 1 to 28 days of age. Thus, a total of 180, day-old broilers chicks were divided into five groups (36 broilers/group in 6 replicates of 6 broilers/replicate). The chickens were fed the same corn-soybean meal basal diet and were submitted to one of the following five dietary treatments: (a) positive control group, fed the basal diet supplemented with MOS at 1g/kg feed; (b) negative control group, fed the basal diet without supplementation; (c) thyme oil 1.0 (TO_1.0) group fed TO at 1.0 g/kg feed, (d) thyme oil 1.5 (TO_1.5) group fed TO at 1.5 g/kg feed and (e) thyme oil 2.0 (TO_2.0) group fed TO at 2.0 g/kg feed. The TO_1.0 displayed a better feed conversion ratio (FCR) than did the other treatments (p < .01). The MOS, TO_1.5 and TO_2.0 groups had higher (p < .01) plasma total protein than the control, and TO_1.5 also increased plasma globulin (p < .01) compared to the control, but decreased plasma albumin/globulin ratio. Moreover, the TO groups significantly decreased the plasma AST. Groups on the MOS and TO_1.0 diets showed higher (p < .01) white blood cells (WBCs) than the other groups. In addition, the MOS and TO_2.0 groups exhibited a greater (p < .01) antibody titre to infectious bursa disease (IBD) than the control group. In conclusion, TO at 1.0 g/kg diet may be used as a potential growth enhancer for broilers in hot region during 1-28 days.ARTICLE HISTORY

“…Najafi & Torki (2010) indicated that dietary supplementation with essential oils (thyme, cinnamon and clove) did not affect cholesterol or HDL level in broilers. Hong et al (2012) showed that broilers supplemented with essential oil (oregano, anise and citrus peel) had higher HDL and lower VLDL levels compared with the controls, while no effect was observed on LDL concentrations.…”

Present study was conducted to investigate the effects of the dietary supplementation of coriander oil on broiler performance, blood characteristics, microbiota, and small intestine morphology measurements. A number of one-day-old broiler chickens (Ross 308) were allocated to five treatments, with four replicates according to a completely randomized design (CRD). Birds were offered either a cornsoybean meal basal diet (control), or the basal diet supplemented with 600

“…Modification NRC nutrient recommendations (Maroufyan et al, 2010;Fanooci and Torki, 2010), using feed additives like enzymes (Zangiabadi and Torki, 2010), organic acids (Mahdavi and Torki, 2009) or medicinal plants (Ghasemi et al, 2010;Najafi and Torki, 2010) has been reported by other researchers. A patented enzyme product (β-mannanase, Hemicell) has been shown to improve feed conversion in cornsoybean diets fed to layers (Zangiabadi and Torki, 2009).…”

Problem statement: Using Guar Meal (GM) in poultry diets has being limited because of having β-mannan, one of the Nonstarch Polysaccharides (NSP). In this study we try evaluating effects of enzyme supplementation of GM-included diets on productive performance of laying hens. Approach: A total number of 144 Lohmann LSL-Lite hens were divided in 24 cages (n = 6). Based on a 3 × 2 factorial arrangement of treatments, six iso-caloric and iso-nitrogenous diets including 3 levels of GM (0. ) with and without enzyme (Hemicell® a β-mannanase-based enzyme, 0.0 and 0.6 g kg ) were assigned to hens in 4 cages (replicates). Data was analyzed based on completely randomized design using GLM procedure of SAS. Results: Dietary GM inclusion significantly affected on Egg Production (EP) on weeks 2, 4 and 6 as well as the overall trail period. Hens fed the GM-included diets did have decreased EP compared to hens fed the control diet. Almost the same trend was observed in terms of Egg Mass (EM); so that hens fed the GM-included diets showed decreased EM compared to the hens fed the control diet. Enzyme supplementation did not have significant effect on EP in the present experiment, but EM was significantly improved in the hens fed the β-mannanase-supplemented diets on weeks 3, 6 and the overall experimental period. Dietary inclusion GM increased Feed Conversion Ratio (FCR) of laying hens compared to the hens fed the control diets on weeks 2, 4, 6 and overall trial period. Conclusion/Recommendations: Including GM in laying hens' diets more than 3% may decrease productive performance. Supplementing cornsoybean or corn-soybean-GM diets by β-mannanase would have beneficial effects on performance of hens especially in terms of FCR and EP.
