This study was conducted to determine the effects of supplemented curcumin (CMN), derived from plant Curcuma longa, extract on performance and blood parameters of acetaminophen (ACT) induced quail hepatic injury. 240 quails from 0-37 days of age were used in a completely randomized design with 4 treatments of 4 replicates each and 15 chickens per replicate. All groups received 750 mg/kg body we...
this study was carried out to determine the effect of different levels of clove essential oil, as a natural growth promoter and probiotic on performance,carcass traits and serum components of broiler chickens. a total of 240 straight run day-old commercial broiler chicks (cobb 500) were distributed randomly into five groups. each group was subdivided into four replicates with 12 chicks each. th...
This research was conducted to investigate the effect of feeding processed shrimp waste products with gamma radiation on performance, carcass characteristics, blood parameters, liver enzymes and digestibility of broiler chicks. In this experiment, 560 one-day male broiler chicks (Ross 308) were allocated to 7 treatments, 5 replicates and 16 chicks per replicate in a completely randomized d...
A study on the effect of probiotic supplementation on broiler peiftmnance was carried out with 600 one day-old Avian broiler chicks. The duration of study was 35 da)lS and a commercially prepared lactobacillus culture was given to the treated birds via drinking water thmughout the 35 days. The results showed that the live weight of the I,·ealed bird was significantly (P<0.05) improved al 21, 28...

The present study was conducted to investigate whether dietary essential oils could affect growth performance, relative organ weights, cecal microflora, immune responses and blood profiles of broiler chickens fed on diets containing different nutrient densities. A total of eight hundred-forty 1-d-old male broiler chicks were randomly allotted into twenty-eight pens (7 pens per treatment, 30 chi...
This study was carried out to evaluate the duration of time of feeding starter and finisher diets on live performance and carcass characteristics of female broilers. Starter diet was fed to 14 or 21 days of age. Finisher diet was fed beginning at 35 or 42 days up to 49 days of age. The results indicated that reduction of duration of feeding starter diet reduced weight gain (P<0.0071) and impair...
The experiment was to study the effects of replacing soybean meal by rubber seed meal on growth, economics and carcass characteristics of broiler. A total of 150 day-old commercial broiler (Cobb-500) was reared for a period of 35 days. There were five treatments including T0 (without rubber seed meal), T1 (10% rubber seed meal), T2 (20% rubber seed meal), and T3 (30% rubber seed meal) and T4 (4...

The effects of different levels of metabolizable energy and energy to protein ratios on the performance of Fars native laying hens were examined during the second laying phase. In a feeding trial, 216 Fars native hens 42 weeks old were randomly allotted to 9 experimental diets using 6 replicated groups of 4 birds per cage. The diets were formulated with 3 levels of ME (2700, 2900 and 3100 kcal/...
