This experiment was conducted to examine the effect of multi-strain probiotic (Primalac) on performance, immune responses and cecal microflora in broiler chickens under cyclic heat stress condition. A total of 96 one-d-old mixed sex broiler chicks (Ross 308) were weighed and randomly allocated to two treatment groups, each with 4 replicate pens of 12 chicks. The dietary treatments were basal di...
an experiment was conducted to investigate the effects of different levels of rapeseed meal and diet formulation based on total and digestible amino acid (aa) using 192 day old ross 308 male broiler chicks. experiment was carried out using a complete block design with 4*2 factorial arrangements. the factors included different levels of rapeseed meal (0, 10, 20 and 30%) and two method of aa form...
The present study was conducted to evaluate the effects of dried citrus pulp(0, 5, and 10%) and pectinase enzyme supplementation (0 and 2000 unit per kg) on feed intake, body weight gain, feed conversion ratio, nutrient digestibility and the internal organ size of broiler chickens. A total of 240 one day old male Ross 308 broiler chicks were used in a factorial arrangement (2×3) based on a comp...
This experiment was conducted in a completely randomized design with five treatments and four replications. There were 15 chicks in each replication during the first 30 days and 10 chicks from day 30 to the end of experiment. Diets were control (without probiotic and dry whey) and levels 500 and 750 gm/ton probiotic, and each level contained two diets with and without %2 dry whey. Daily weight ...

this experiment was conducted to evaluate the effects of dietary salvia mirzayanii supplementation on performance, carcass characteristics, internal organs and cecal microbial population in broilers. a total of 200, one-day-old broiler chicks (ross 308) were fed five experimental diets containing different levels of s. mirzayanii (zero, 0.25, 0.50, 0.75 and one percent of diet) until 42 days of...
A 2×2×2 factorial arrangement with control group was conducted to study the effect of different levels of microbial phytase, metabolizable energy and available phosphorus on performance, carcass characteristics and phosphorus and calcium content of tibia in broiler chicks. In this experiment, 1260 Ross 308 male broiler chicks allocated to 9 treatments in a factorial arrangement, with 2 levels o...
The influence of dietary oxidized oil was studied on laying hen performance, egg quality and blood metabolites. Experiment was conducted on 160 laying hens (Hy-Line W-36, 54-61 wk of age) in a completely randomized design with five treatments and four replicated cages containing eight birds per cage. Dietary treatments replaced fresh soybean oil in the control diet (3% fresh soybean oil, 15.25...
the effects of probiotic (protexin) and formic acid were studied on humoral and cellular immunity in 200 cobb broiler chicks in a completely randomized design of with 4 treatments and 5 replications (10 observations per replicate). control group (c) did not receive any other than the base treatment. the chicks in the second (p), third (f) and forth (p+f) groups were fed with feed, which contain...
this experiment was conducted to evaluate the effect of the addition of a multi enzyme (natuzyme-p) to corn-soybean based diets and to determine the enzyme's nutrient equivalency on broiler chicks’ performance. ninety six day-old male broiler chicks were randomly assigned to a number of 24 battery cages in a completely randomized design. the chicks were grown up to 6 wk of age. six diets (...
