Abstract
Two hundred and forty one-day-old male broiler chickens (Ross-308) were randomly distributed into four groups, each of which had four replicates and 15 birds in each. The birds used to evaluate the effects of turmeric rhizome (Curcuma longa L.) and protexin (as multistrain probiotics) alone or their combination, on performance traits, serum lipoproteins, cecum micro flora and gut morphology of broiler chickens. The chicks received the same basal diet based on corn-soybean meal (T1. control), plus 2g/kg turmeric rhizome (T2), and 0.12g/kg (T3), and combination turmeric and protexin with the same level (T4). The performance traits recorded as weekly and calculated on d 21 and 42. Furthermore, on d 42, four birds (one bird/cage) as randomly selected and samples of gut and chyme had removed to further analysis. Addition of turmeric or protexin to the basal diet significantly increased (P<0.05) average daily gain of broilers on d 42. The feed-to-gain ratio was significantly decreased (P<0.05) for the birds fed diets with combination additives in contrast to the control (on d 42). Dietary inclusion of 0.12g/kg protexin numerically (P>0.05) enhanced the mass of Bifidobacterium and Lactobacillus, and the number of E. coli decreased in the small intestinal and cecum of chyme (P<0.05) on 42 d. Morphological parameters for the duodenum, and jejunum revealed that no significance difference for villi height (VH), crypt depth (CD), and VH/CD ratio in the birds that fed additives alone. However, VH, CD, and VH/CD ratio in the birds fed diets inclusion of the blend of protexin and turmeric were higher (P<0.05) at the jejunum than control and other treatments. According to the present results, it could be conclude that dietary the blend of protexin and turmeric rhizome increased performance parameters, improved gut micro flora and morphological traits of broilers. Hence, a dietary combination of protexin and turmeric rhizome has a positive effect on the productivity and health of broiler chickens.
