this experiment was conducted to evaluate the effects of using rice bran, combo multi-enzyme and probiotic (protexin) in diet on performance, egg traits, biochemical parameters and blood cells of commercial laying hens. this experiment carried out using 384 hi-line (w36) laying hens in a completely randomized design as factorial (2×2×2) arrangement with two levels of rice bran (0 and 10%), two ...
Broken rice (BR) is one of the important by-products of rice production, which is produced in large scales in northern provinces of Iran. An experiment was conducted to investigate the effect of different levels of BR on egg quality and performance of laying hen, with 5 levels of BR (0, 10, 20, 30 and 40%) in a completely randomization design (CRD) on 90 Hy-line W36 egg-type laying hens f...
This research aimed to compare the effects of pigments extracted from dried petal meal of marigold flower and synthetic pigments on productive performance of laying hens, egg quality and antioxidant properties of the egg. A total of 64 laying hens, aged 75 weeks, were distributed in a completely randomized design in 4 treatments and 4 replications containing 4 hens per cages. Experimental group...
This experiment was conducted to evaluate the effect of graded dietary levels of pure curcuminoid on productive performance, egg quality traits, some biochemical blood parameters, immune response and its digestibility in the late phase of production of laying hens. A total of 160 sixty-weeks-old Hy-Line (W-36) laying hens were used in a completely randomized design, including 4 treatments in fo...
An experiment was conducted to investigate the effects of using different levels of Red Pepper powder (RP) and Marigold flower powder (MF) on egg production, egg yolk color andsome blood metabolites in laying hens. Ninety, 103-weeks old laying hens were divided into 5 treatments groups of 6 birds in each cage with 3 replicates in a completely randomized design. The birds were fed a corn-soybean...

This experiment was conducted to examine the effect of different levels of protein (13 and 15%) and methionine (0.25, 0.30 and 0.35%) on performance and some egg indices in the late laying period of layer hens. Ninety six leghorn 80 weeks W-36 layers were used as a 2×3 factorial arrangement based on the completely randomized design. The results have shown that as methionine level was increased,...
The present study was carried out to determine the effects of fenugreek powder (FP) and extract (FE) on performance, egg quality, blood parameters and immune responses of laying hens. One-hundred and fifty Leghorn laying hens were used in a completely randomized design with five treatments and five replicates for eight weeks. Treatments were various levels of FP and FE including zero (control; ...
This study was conducted to consider the effect of theophylline in laying and some of egg characteristics on laying hens. Commercial egg type Hy-Line hens were used in a completely randomize design with 4 treatments and 3 replicates for 50 days period. The levels of different theophylline supplements (treatment) were 0 (control), one, three, and five mg per kg of body weight for 50 days. The av...
this experiment was conducted to evaluate the effect of increasing levels of alfalfa leaf meal (alm) on egg production, egg traits and blood parameters of laying hens with 144 hy-line (w36) laying hens from 65-75 weeks of age in 4 treatments, 3 replicates and 12 hens in each replicate in a completely randomized design. experimental groups included: 1) control group, 2) group with 1% of alm, 3) ...
