Effect of Dietary Supplementation of Cinnamon and Curcumin on Performance, Carcass Traits, Humoral Immune Responses, and Blood Serummetabolites in Growing Rabbits

Abstract

total of seventy-two V-line rabbits of both sexes, 5 weeks old, with initial weights of 639.4 ±.25.97 g were used for the study. Rabbits were randomly allocated to 6 treatment groups, each of which included 4 replicates of 3 rabbits. The experiment lasted for 6 weeks to be finished at 11 weeks of age and dietary treatments were as follows: 1) Control (basal diet); 2) basal diet+ 100 mg/kg antibiotictylosin; 3) basal diet+ 0.5 g /kg turmeric (as a source of curcumin); 4) basal diet+ 1.0 g/kg turmeric; 5) basal diet+ 0.5 g/kg cinnamon; 6) basal diet+ 1.0 g /kg cinnamon. The results showed that there were significant (P ≤ 0.05) differences in body weight, weight gain, feed intake and feed conversion ratio among treatments and the control group. The highest body weight and weight gain values and the best feed conversion ratio were recorded in the groups given 1.0 g /kg diet turmeric or cinnamon. The highest feed intake values were observed in the control and Tyrosin fed groups, while the lowest feed intake values was recorded in cinnamon fed group. Tylosin, cinnamon and turmeric supplementation significantly (P ≤ 0.05) improved digestibility of DM, OM, CP, CF, EE and NFE and also, improved the nutritive values of nutrients as TDN and DCP in comparison with control. General significant (P ≤ 0.05) increase in RBCs, Hb and PCV % due to the different feed additives in comparison with control group. Serum lipid profile improved by phytogenic feed additives compared with tylosin and control groups. Phytogenic feed additives reduced Malondialdehyde (P ≤ 0.05), while, increased total antioxidant capacity concentrations and glutathione peroxidase activities. Immunostimulatory effects of phytogenic feed additives were recorded. In conclusion, we state that cinnamon and turmeric could have beneficial effects on performance, digestibility, immunomodulatory and play an important role as an exogenous antioxidant.Keywords: Rabbits, cinnamon and turmeric, antibiotic, performance, immunity and blood lipid profile. 1 Vit+Min mixture provides per kilogram contains: Vit A 6000 IU; Vit D 3 450 IU; Vit E 40 mg; Vit K 3 1 mg; Vit B 1 1 mg; Vit B 2 3 mg; Vit B 3 180 mg; Vit B 6 39 mg; Vit B 12 2.5 mg; Pantothenic acid 10 mg; biotin 10 mg; folic acid 2.5 mg; choline chloride 1200 mg; Manganese 15 mg; Zinc 35 mg; Iron 38 mg; Copper 5 mg; Selenium 0.1 mg; Iodine 0.2 mg; Selenium 0.05 mg. 2 Analyzed values according to AOAC (1995).

The Protective Role of Ginger (Zingiber Officinale) on Alleviation of Heat Stress in Broiler Chicken

“…Uric acid is a potent scavenger of free radicals in birds, and high concentrations of ACTH have been linked with elevated rates of uric acid. This may be attributed to higher plasma corticosterone levels caused by heat stress, which in turn raises the blood uric acid content [28]. Chronic heat stress produced a large rise in uric acid as compared to TNC group.…”

Amelioration of Sarcoptic Mange-Induced Oxidative Stress and Growth Performance in Ivermectin-Treated Growing Rabbits Using Turmeric Extract Supplementation

“…Co-treatment of IVM + 1 and 2 mg TE resulted in a progressive recovery demonstrated by reducing the negative effect of single injectable IVM therapy on the performance and physiological functioning of rabbits. In this context, rabbits fed a diet containing 1.0 g/kg turmeric gained the highest body weight and had the best FCR [25,41]. There was a significant improvement in weight gain when TE was included in the diet at 1 and 2 mg, which may be attributed to its active components with an antioxidant activity, which would stimulate protein synthesis by the rabbit.…”

“…These treatments have been shown to increase the protein, albumin, and globulin levels compared with the untreated animals. Zeweil et al [25] observed that different doses of turmeric (0.5 and 1.0 g/kg) significantly decreased triglycerides and LDL compared with the control group. In addition, [42] found that increasing turmeric levels to 7 g/kg diet significantly decreased the triglycerides and total cholesterol.…”

“…Curcuminoids and curcumin of turmeric were found to increase feed utilization, resulting in an improved growth performance [42]. According to Zeweil et al [25], feeding rabbits a diet supplemented with 1g of turmeric/kg increased the digestibility of DM and CP compared with the control. It was shown that TE at a dose of 0.04 mL/kg of body weight had the best digestibility coefficient for OM and CP compared with the control group [49].…”

“…Turmeric has a wide range of health benefits at a low cost and no has negative effects on livestock production [24]. Due to its vitamin and mineral content, turmeric has also been used as dietary supplementation that improves feed intake, nutrient digestibility, and growth performance in rabbits [25]. Although the efficacy of IVM in treating scabies worldwide has been well established, little is known about its side effects in rabbits [26].…”
