Effect of dietary supplementation of α-calcidiol on growth performance and carcass traits of broiler chicken

The research was conducted to study the effect of feeding broiler chickens on diets containing isomaltooligosaccharides on the growth performance, carcass traits and immune response. 90-one day old broiler chicks were used according to completely randomized two treatment groups and one control, 30 birds each. Birds fed ad-libitum on basal starter and grower-finisher diets for 35 day. Diets of treatment`s groups contained 0.5 g/Kg and 1 g/Kg of Isomaltooligosaccharides, while the control group fed on the basal diets without Isomaltooligosaccharides supplementation. Dietary supplementation of broiler chickens with Isomaltooligosaccharides improved body weight, feed conversion, carcass traits, two lymphoid organs weight and log antibody titer against avian flu vaccine. Most of the highest values were for birds fed low levels of Isomaltooligosaccharides. Feed intake decreases as Isomaltooligosaccharides level increases. Dietary supplementation with Isomaltooligosaccharides did not affect the lipids profile (triglycerides, total cholesterol, LDL and HDL), however the blood VLDL levels decreased with increased levels of Malondialdehyde and Glutathione reductase. Collectively, Dietary supplementation of broiler chickens with 0.5 g/Kg diet of Isomaltooligosaccharides improved growth performance, carcass traits and immune status.

The objective was to explore the possible impacts of dietary supplementation with a synbiotic, organic acids or their combination on the growing efficiency, carcass traits and some blood constituents in broilers. In total, 160 1-day-old male broilers (Ross 308) were randomly assigned into four equal groups (40 birds with 8 replicates). The control group received the basal diet with no supplements, while diets of the treated groups were supplemented with organic acids (OA; 1 g/kg), a synbiotic (S; 1 g/kg) and an equal mix of OA and the synbiotic (OS; 2 g/kg). The dietary supplementation with OA decreased the feed intake (P = 0.011) and bodyweight gain (P = 0.011) when compared with other experimental groups. However, the dietary supplementation with the synbiotic plus OA resulted in a considerable improvement in the overall feed conversion rate when compared with the control and OA-supplemented groups (P = 0.001). Groups fed the diets supplemented with the synbiotic or the synbiotic plus OA showed significantly higher net profits and the profit to cost ratio than did the CON and OA-supplemented groups (P = 0.010 and 0.005 respectively). Birds in the S and OS groups had a significantly higher jejunum villus height (P = 0.001), and carcass (P = 0.012) and breast meat (P = 0.001) yields than did those in the control and OA groups. However, the synbiotic-supplemented group produced significantly lower abdominal fat percentage (P = 0.021). The dietary supplementation with the synbiotic or the synbiotic plus OA decreased the lymphocyte counts (P = 0.003) and the serum reduced glutathione concentration (P = 0.001), but significantly decreased the heterophil to lymphocyte ratio (P = 0.001), and the serum cholesterol (P = 0.014) and oxidised glutathione (P = 0.002) concentrations compared with the control and OA-supplemented groups. The present findings showed that dietary supplementation with a synbiotic or a synbiotic plus OA can improve the growth performance, carcass traits, serum antioxidant activity and blood-related indices in broilers.

Abstract This study was performed to investigate the effects of dietary supplementation with garlic and turmeric powder as growth promoter agents on performance, carcass traits, serum biochemistry, and antioxidant enzyme activities of growing rabbits. A total of 112 New Zealand White rabbits (NZW) at 5 weeks of age were randomly assigned to seven treatments with four replicates. The dietary treatments consisted of 7 groups as follows; the basal diet as control, phytogenic additives groups were supplemented with 2, 4, and 6 g/kg garlic or turmeric powder added to the basal diet. There were no linear and quadratic differences (P<0.05) in growth performance after garlic or turmeric supplementation at all studied ages. Compared with the control group, supplementation of diets with garlic or turmeric linearly and quadratically elevated immunity biomarkers such as total protein (TP), albumin (AL) and immunoglobulin (IgG) levels and decreased (linearly and quadratically, P<0.05) aspartate aminotransferase (AST), alanine aminotransferase (ALT ), triglyceride (TG) and total cholesterol (TC) levels in rabbit serum. However, TP, AL, globulin (GL), IgG and IgM levels were linearly and quadratically enhanced with increasing turmeric levels versus the control diet. Hepatic superoxide dismutase (SOD), catalase (CAT ) and glutathione peroxidase GSH-Px activities as well as reduced glutathione (GSH) concentrations were linearly and quadratically (P<0.05) improved in garlic or turmeric additives fed groups. While MDA concentration was statistically (linearly, P= 0.022) reduced in comparison with the control group. It could be concluded that garlic or turmeric supplementation (2, 4 and 6 g/kg) did not linearly and quadratically affect growth performance but improved the immunity responses and lowered the lipid profile in blood and lipid peroxidation in liver and increased hepatic antioxidant activity in treated rabbits.
