400 one day-old broiler chicks were allocated on a randomized complete design experiment with five treatments consisting of four replications for 42 days. experiment treatments were included: 1 . based diet consist 20 percent barley (barley control), 2 . barley control + 0.1 percent of mixed essential oil (antibiofin), 3 . barley control + 0.2 percent organic acid, 4 . barley control + 15 ppm o...
This experiment was conducted to determine the effects of replacing corn by 20% barley supplementedwith probiotic, prebiotic and antibiotic on performance, immune response, intestinal morphology, carcass development and nutrient digestibility of broilers. Four hundred Ross 308 one day-old broiler chicks were assigned randomly to 5 dietary treatments and were tested for 42 days in a com...
the present experiment was carried out to determine the effects of antibiotic growth promoters, blend of medicinal plants, prebiotic and organic acid on performance and nutrients apparent digestibility in a six week period, using one hundred ninety two one- day- old broiler chicks (cobb 500) on a randomized complete block design experiment with six treatments consisting of 4 replications and ...
to evaluate the efficiency of nanocid as growth promoter in comparison antibiotics and with organic acids on performance and intestinal morphometric characteristics of broiler chickens, 240 male broiler chicks of one dayage (ross 308) were utilized in an experiment of a completely randomized design of 4 treatments and 4 replicates. the experimental treatments included: 1) control (no additives)...
abstract this study was carried out to compare disinfecting effects of nanosilver with other feed disinfectants on layer hen performance, immune system, gastrointestinal microflora and intestinal morphology. total of 90 layers (lsl) were divided into five groups consisting: 1-control, 2- formalin (200 ppm), 3- formaycin (200 ppm), 4- nanosilver in drinking water (7.5 ppm) and 5-nanosilver in f...
Three trials were conducted with 252 pigs to determine the effects of the dietary additions of Cu (250 ppm as copper sulfate), with and without sulfide (500 ppm as ferrous sulfide), and antibiotics (55 ppm chlortetracycline or 27.5 ppm virginiamycin) on the performance and liver Cu stores of growing-finishing pigs. Single additions of Cu, chlortetracycline or virginiamycin to a 16% protein, cor...
in this research, we investigated the effects of medicinal plants, prebiotic and probiotic as alternatives to antibiotics on the growth performance, immune response and blood cholesterol in broilers. a total of 288 one- day-old broiler chicks (cobb 500) were randomly assigned to 6 treatments and replicated 4 times with 12 chicks per pen in a completely randomize design experiment in 6 wk. diet ...
This research was conducted to compare the effects of two medicinal plants (peppermint and aloe vera) and antibiotic growth promoter on ileum microflora population and growth performance of broiler chickens. In this experiment, 375 one-day old male broiler chickens (Ross 308) were used on a completely randomized design with 5 dietary treatments which were replicated 5 times with 15 birds per re...
this research was conducted to examine the effect of a concurrent training on rest level of leptin of plasma and some hormonal factors in non-athlete subjects. the research population included non-athlete men who didn’t participate in any organized sport activities. 30 men were chosen voluntarily among the above-mentioned population and were divided into 2 groups: experimental (15 subjects) an...
A semi-field study was carried out to evaluate the effect of two medicinal herbs, individually and in combination, on growth performance, carcass traits, nutrient digestibility and immune response of broiler chickens. A total of 384 one-day-old straight-run Arbor Acres broiler chickens were allocated into 24 floor pens prepared in a commercial broiler house. Pen-groups were fed one of the foll...
