Turmeric (Curcuma longa Linn.) as a phytogenic growth promoter alternative for antibiotic and comparable to mannan oligosaccharides for broiler chicks

Abstract

This work aimed at investigating the potential as a growth enhancer of different dietary concentrations of turmeric (Curcuma longa Linn.) as an alternative to oxytetracyline and antibiotics and as comparable to mannan oligosaccharide for broiler chicks. A total of 252 Hubbard broiler chicks at one day of age were distributed randomly in a straight run experimental design among six treatments, each replicated seven times, with six unsexed chicks per replicate. The basal diet was administered without supplements (control group) or supplemented with turmeric at 0.5, 1, and 2 g/kg diet, or with mannan oligosacride (MOS) at 1 g/kg feed or with oxytetracycline (OTC) at 50 mg/kg feed. Growth performance, carcass characteristics, meat quality traits, blood biochemical constituents, antioxidant status and red blood cell (RBCs) were investigated. Turmeric supplementation at 1 g/kg feed significantly improved feed conversion ratio (FCR) and European production index compared to the control group and MOS groups. The results indicated that turmeric can be used at 1 kg/t feed as a phytogenic feed additive as an alternative to OTC or MOS without negative effects on the productive and economic traits of broilers. There were no differences from using OTC and MOS, while there was an increase in the European production efficiency index and the broilers’ health status.

Effects of dietary supplementation with nanocurcumin on quality and safety of meat from broiler chicken infected with Eimeria species

“…reported that dietary supplementation with curcumin did not affect textural characteristics of broiler chicken meat (Negari, Isroli, & Nurwantoro, 2015). Similar to our findings, Attia et al reported that there was no significant effect of turmeric extract on textural characteristics of broiler chicken meat (Attia et al, 2017).…”

“…Dietary supplementation with curcumin could increase plasma thyroid hormone (T4) level (Rajput, Muhammad, Yan, Zhong, & Wang, ). Nanocurcumin supplementation improved villus height and width which can enhance nutrient absorption (Attia, Al‐Harthi, & Hassan, ; Rahmani, Golian, Kermanshahi, & Bassami, ; Rajput et al, ). The results of the current study are in good agreement with Durrani et al, who reported higher dressing percentage and breast and thigh weights of broilers fed a diet containing 5 g/kg of turmeric powder (Durrani et al, ).…”

Effects of Ananas comosus leaf powder on broiler performance, haematology, biochemistry, and gut microbial population

“…Their use as growth promoters is prohibited in many countries (Attia et al, 2011). Alternative growth promoters from herbal plants and their bioactives are becoming more important because of their antimicrobial effects and digestion-enhancing capacities (Dhama et al, 2015;Attia et al, 2017a;Attia et al, 2017b).…”

Blood parameters and hepatic histopathology of broilers fed rations supplemented with essential oils

“…In contrast, the use of organic acids, enzymes, pre-and probiotics, and essential oils may result in higher performance and better intestinal health without the inconvenience of antibiotic resistance (Dhama et al, 2015;Zeng et al, 2015;Cho et al, 2014;Krishan and Narang, 2014). Variable results have been obtained using oils for antimicrobial purposes, such as rosemary (Traesel et al, 2011), thyme (Saleh et al, 2014;Toghyani et al, 2011;Toghyani et al, 2010;Tollba et al, 2010;Attia et al, 2017b), and ginger (Mehr et al, 2014) oils. However, the possible toxic effects and/or changes in metabolism caused by essential oils still generate doubts regarding their safety.…”

“…Current research aims at evaluating the effect of phylogenics and essential oils on biochemistry and blood components. Available results are promising, indicating no changes in physiological parameters and improvement of the health status of treated birds (Attia et al, 2017b;2018;Bortoluzzi et al, 2018;Chowdhury et al, 2018;Mokhtari et al, 2018).…”
