this experiment was carried out to study the effects of different levels of canola meal of different fat sources on the egg quality, performance as well egg yolk cholesterol during the first 12 weeks of age in laying hens (hy-line w-36). throughout the experiment a total of 432 hens were employed in a completely randomized design in a factorial arrangement of 3×4, with three levels of canola me...
This experiment was conducted to investigate the effects of different levels of L-carnitine on productive performance, egg quality and blood parameters in laying hens. Forty-eight Hy-Line W-36 egg Layers were weighed at 90 weeks of age and randomly allocated into 16 cages (three hens per cage). Four dietary treatments were prepared by supplementing L-carnitine (0, 50, 100 and 150 mg/kg of diet)...

1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...
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 study was conducted to investigate the effects of different levels of black cumin powder on performance, yolk cholesterol content and egg oxidative stability in laying hens. A total of 96 Leghorn laying hens (Hy-Line W-36) of 25 weeks old were randomly distributed among eight cage replicates of three birds each. Experimental diets consisted of different levels (0, 5, 10 and 15 g/kg of diet...
A 3 × 2 factorial arrangements with completely randomized design, with a total of 72 Leghorn Hy-line (W-36) laying hens in the second cycle (98 wk old) of production were randomly assigned to 24 wire cages (45.7×30×30 cm3) and fed with diets containing three levels of guar meal (GM; 0, 4 and 8%) and two levels of β-mannanase (Hemicell®) enzyme (0.00 and 0.05%) for 12 wk period. There...
An experiment was conducted to evaluate the effects of different levels of mineral and vitamin premix on performance and egg traits of laying hens from 37 to 49 weeks of age. Two hundred and forty laying hens (Hy-Line W-36 strain) were randomly assigned to 5 dietary treatments of four replicates each with 12 hens per replicate). The levels of mineral and vitamin premixes in the experiment were ...
