A total of 700 day old female broiler chicks (Ross 308) were distributed into seven groupsin acompletely randomized designwith five replicates, and 20 chicks in each replicate. Dietary treatments, timeof the switch from an unsaturated sunflower oil (SFO) to a saturated tallow (T)dietary fat source, were: 1) SFO for the entire growth period (6 weeks), 2) SFO for 5 weeks followed byT for last wee...

This experiment was carried out to evaluate the effects of four levels of dietary threonine (Thr) supplementations on growth performance, gut size and histomorphometric alterations of small intestines in broiler chicks in 1-14 days. Two hundred eighty-eight Ross 308 one-day-old male broiler chicks were randomly assigned to four treatments with six replicates (12 birds per replication) received ...

This experiment was undertaken to evaluate the effect of dietary level of artichoke (Cynara scolymus) on growth performance and immune response of broilers under heat stress (HS). Two hundred forty day-old broiler chicks (Ross, 308) were randomly assigned to one of four dietary treatments with four replicate pens per treatment (15 birds per pen) in a completely randomized design with a 2 × 4 fa...

effect of natural zeolites and nano-zeolite on gut flora, tibia bone characteristics, blood parameters and performance of broilers investigated with 336 male ross 308 broilers chicks allocated to   seven treatments with four replicates and 12 chicks per each. experimental treatments were control (no zeolite supplemented), natural zeolite (0.5, 1 and 1.5 percent) and nano-zeolite (0.5, 1 and 1.5...

Two hundred eighty days old male broiler chicks(Ross strain) were randomly distributed into seven groups with four replicates (10 birds in each replicate) and were fed diets supplemented with different dietary fat sources.The results indicated that the different dietary treatments did not affect weight gain, feed intake and feed conversion ratio at 21 d (P>0.05). However, addition of dietary fa...

The present study was carried out to examine the effect of supplemental dietary valine in the starter diet of broilers (0-15 d of age) on performance, antibodyresponse to Newcastle disease virus vaccination and bone mineralization. The experiment was conducted using 300 Ross 308 male broilers. One-day-old chicks were randomly allotted to 3 groups; each group consisted of 5 replicate pens with 2...

This study was conducted to determine the effects of three different fat sources and their combination on growth performance, carcass traits and intestinal measurements of broiler chickens reared to 42 d of age. Two hundred day-old male broiler chicks (Ross 308) were randomly assigned to one of five treatments with four replicates of 10 chicks based on a completely randomized design. The dietar...

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...

Abstract The purpose of this research was to examine the impact varying doses ginger powder on broiler productivity. There were 180 commercial strain Ross 308 day old chicks utilized in experiment, and each chick weighed allocated randomly among four treatments. Three different treatments tested, with a replication 15 chicks. diet supplemented 0.5, 1.0 2.0g/kg powder, respectively, as control. ...
