this study was carried out to investigate the effects of humulus lupulus essential oils as an alternative to antibiotic and antioxidant on productive performance, lipids stability of meat and ileum microbial population in broiler chickens during days 1 to 42 of age. a total of 625 day-old arian broiler chicks were used in a completely randomized design with five treatments (200 and 400 mg/kg hu...
The effects of Trigonella foenum graecum (TF) and Foeniculum vulgare (FV) seeds powder on antimicro-bial activity and performance of broiler chickens were studied. Based on a completely randomized design, 240 broiler chicks (Ross 308) were assigned to 4 treatments and 4 replicates. The treatments were a basal diet (control, T 1), T 1 plus 0.5% TF (T 2), T 1 plus 0.5% FV (T 3) and TFFV (0.25% TF...
The purpose of this experiment was to compare the effects of essential oils blend with probiotic and Flavomycin as antibiotic growth promoter on humoral immunity, meat quality, and some blood parameters in broiler chickens. A total of 288 day old Ross 308 strain broiler chicks based on a completely randomized design was allocated to four treatments with four replicates and 18 birds in each repl...
nowadays, technical terminology translation plays an important role in human life. specific groups of people all over the world refer to learn these terminologies in order to be familiar with a subject and improve their knowledge in that domain. on the other hand, saving the technical translation equivalent is a particularly salient challenge for technical translators. the present study was con...
The objective of the present study was to determine the best dietary level of L-arginine on the growth performance, carcass traits, and blood parameters of female Ross broiler chickens in the starter and grower periods. In this experiment, 192 day old female Ross broiler chicks were fed with 4 dietary treatments in a completely randomized design, in which each dietary treatment included 4 repli...
The present study was aimed at studying the effects of inclusion of pomegranate seed extract to fat-containing diets on nutrients digestibility, intestinal microflora and performance of broilers. A total of 320 one-day-old broiler chicks (Ross 308) were selected in a 2 × 2 × 2 factorial experiment in a completely randomized design with 4 replicates o...
This study was conducted to investigate the effects of L-carnitine and different levels of animal fat on performance, carcass characteristics and some blood parameters of broiler chickens. Two hundred one-day old male broiler chicks were allotted to5 treatments in 4 replicates and 10 birds in each replicate. Dietary treatments consisted of: 1) diet with 5% vegetable oil (T1), 2) diet with 5% ve...
This experiment was conducted to evaluate the effects of caffeine and trans-cinnamaldehyde (TC) on growth performance, hematological parameters, stress hormones, immune response, and some blood parameters of broiler chickens. Three hundred fifty 1-d-old broiler chicks were randomly assigned to 7 dietary treatments (five pens/ treatment of 10 male broilers each) in a completely randomized desig...
This study investigated the effectiveness of clove and cardamom alcoholic extracts as growth promoters on performance, carcass traits, some blood serum components, immunity parameters, intestinal microbial population morphology broiler chicks. To this purpose, a total 240 one-day-old chicks (Ross 308 strain) were distributed randomly into three groups in form completely randomized design. The e...
the objective of the present study was to investigate the effects of dietary l-arginine on performance, meat production and its chemical composition, carcass fat deposition, intestine morphology and blood parameters of ross broiler chickens during 46 days. in this experiment, 192 day old commercial female ross broiler chicks were used with 4 dietary treatments and 4 replications in a completely...
