Effect of garlic powder supplementation on Production performance, meat quality, blood Parameters and lipid profile of coob 500 broilers Chicken

Abstract

Feed is the major bottleneck of poultry production in Ethiopia. Therefore, the aim of this experiment was to evaluate the effects of different level of garlic powdersupplementation on production performance, meat quality, blood parameters and lipid profile of coob 500 broilers chicken. A total of 180 unsexed day old (Coob500) broiler chicks were randomly allocated to four dietary treatments within three replicates in completely randomised design (CRD). The chickens were fed on three phase basal diets; starter, grower, and finisher diets. The dietary treatments consisted of T1=control (basal diet +0% of garlic powder), T2 (basal diet +1% of garlic powder, T3 (basal diet +3% of garlic powder), T4 (basal diet+5% of garlic powder). Growth performance, carcass yield and meat quality, haematology, serum biochemical and economic analysis were observed. All data were subjected to General linear model procedure of (SAS version 9.3, 2011). The result revealed that the chickens kept on T3 showed the highest (P<0.05)final body weight (2390.71g±14.96g), feed intake (4264.54g±25.92), low and better feed conversion efficiency (1.77±0.002), followed by group of birds fed on T2 final body weight (2185. 23g±51.29g), feed intake (3945.32g±169.1) and feed conversion ratio (1.80 ±0.04). The group of chickens kept on T4 attained the lowest growth performance (final body weight 1936.42g±34.06, total feed in take 3645g± 59.37and feed conversionratio(1.84±0.028). The highest dressed weight, drumstick with thigh , breast meat, and back weight was obtained from the group of birds fed on T3. The group of chicken fed on T3 showed the highest crude protein percentage (22.95±0.132) of breast meat as compared with T1 (17.77±0.69). Blood analysis revealed that T3 has showed the highest Total white blood cells count and lymphocyte (18.91±1.7 x 103/ul; 75.83 ± 6.05 percent as compared with control (T1)13.13±1.02 x 103/ul, 61.056±6.05 percent. The serum analysis of the broilers chickens fed different garlic level was significantly (P<0.05) different between the treatments. The low blood cholesterol content was observed in T3 and T4. The Group of chickens fed on T3 have chol(110.5mg/dl±10.83mg/dl),triglycerides(77.16mg/dl±12.15mg/dl), and T4 chol (108.66mg/dl±6.34mg/dl), triglyceride(104.16mg/dl±15.734mg/dl) as compared with T1 (control)185.33±28.28mg/dl,153.153 ±11.35mg/dl). There was significant (p < 0.05) increase in the level of high density lipoprotein in T3 (91.43±1.03 mg/dL) in comparison with other treatments.The partial budget analysis of the garlic supplementation illustrated that T2 and T3 had showed more net return (10347.55 ETB) and (11085.60ETB) as compared with control group (10000.4ETB).The lowest net income was obtained from the birds fed onT4 (7431.50ETB). Thus, it’s concluded that supplementation of garlic powder at1-3% level showed significant improvement in overall performance, haematological, biochemical profile and achieved best net return. Hence, to make efforts and more Comprehensive extra investigation should be desired on efficacy of garlic extract , garlic husk and leafs of the plant in the diferrant regions of the countries
