This study was conducted to investigate the effects of different levels of dried whey and protexin probiotic on the productive performance, carcass trait and blood parameters of broiler chickens. In this study, 360, one-day old male and female commercial Ross 308 broiler chickens of mixed gender were used in a randomized design with four treatment (six replicated in each treatment and 15 birds/...

To determine the effect of using Aloe vera and protexin probiotic on performance, carcass characteristics and some blood biochemical in Japanese quails, a total 300 ten days old Japanese quails quail chicks with an average weight of 19.5±5 g were divided into 8 treatments with 3 replicates as factorial randomized design experiment. The quails were fed by basal diet as control diet, (0 and 1 g.k...

The present study was conducted to investigate the effects of four different levels of dietary probiotic (protexin) on productive traits and egg quality of broiler breeder hens. One hundred sixty female 64-week-old broiler breeders (Hubbard classic) were involved in this experiment. The birds were randomly assigned to control Group A (unsupplemented diet), Group B (0.25% protexin supplemented d...

To investigate the effect of bactocell and protexin probiotics on performance and carcass characteristics of broilers, an experiment was conducted with completely randomized design with 3 treatments in 4 replicates and 25 day old female cobb 500 broiler chickens for each replicate for fortytwo days. Treatments include: 1-Control diet (without probiotics), 2-Control diet containing bactocell pro...

to consider the effect of probiotic and organic acids on performance, carcass characteristics, blood parameters and immune response of broilers, a completely randomized design test was done with four treatments and four replicate for each reatment. two hundred and forty one day-old mixed sex broilers (ross breed) were divided into four treatments with 15 chicks per each replicate (pen). treatme...

This study was conducted to investigate the effects of protexin probiotic and aquablend avian antibody on the performance and immune system of broilers. In this experiment, 320 1-day-old male broiler chicks of the Ross 308, with 5 treatments and 4 replications in a completely randomized design were distributed in experimental units (cages). The treatments include: control (C), protexin (P1), pr...

the effect of a commercial probiotic (protexin) on growth performance and survival rate in sobaity sparidentex hasta was investigated. 240 fish with average weight of 2.99±0.87g were treated for 10 weeks. this study was carried out in a completely random design with 12 experimental groups, in 4 treatments each with 3 replicates. experimental groups were consisted of four levels of 0.0, 0.5, 1.0...

this experiment was conducted to investigate the effects of using protexin, propionic acid growth promoters, and a blend of them on broilers performance. in a completely randomized design, three hundreds and twenty unsexed 1-d-old chicks were divided into four groups. dietary treatments were consisted of 1) control diet without any supplement, 2) the control diet + 0.01 % protexin, 3) the contr...

In this study, the effects of Protexin and artichoke extract (AE) were evaluated on performance oxidative stress chickens. Totally, 300 chicks divided into 4 groups that fed a basal diet, diet containing Protexin, AE, plus AE all over growing period. The growth indices measured weekly analyzed at 21 42 days age. At age, blood samples collected from concentrations liver enzymes, lipid profiles, ...
