[ 1 ] - اثر سطوح کنجاله آفتابگردان و آنزیم پروتئاز بر صفات عملکردی و ریخت شناسی روده باریک در مرغ های تخم گذار
این آزمایش به منظور بررسی اثر سطوح کنجاله آفتابگردان و آنزیم پروتئاز بر عملکرد، صفات کیفی تخم مرغ و ریخت شناسی روده باریک در مرغ های تخم گذار از سن 78 تا 86 هفتگی انجام شد. مجموعا 120 قطعه مرغ تخم گذار سویه بونز وایت در 6 تیمار و هر تیمار شامل 5 تکرار و 4 قطعه مرغ در هر تکرار بصورت آزمایش فاکتوریل 2×3 در قالب طرح کاملا تصادفی استفاده شد. تیمارهای آزمایشی شامل 3 سطح (صفر، 78/6 و 56/13 درصد کنجال...
[ 2 ] - The Effect of Prebiotic and Types of Feed Formulation on Performance, Intestinal Microflora and Cecum Gas Production of Laying Hens
In this experiment, the effect of prebiotic Bio-Mos® (MOS) and types of feed formulation (total and digestible amino acids) were evaluated on performance and the small intestine microflora in laying hens for a duration of 10 wks. A total of 168 Hy line W-36 laying hens, with an initial age of 73 wks, were randomly allocated to 4 dietary treatments, 7 replicates and 6 birds in each replicate. Th...
[ 3 ] - Amino Acid Digestibility and Energy Value of Bitter Vetch (a Cheap Plant Protein) and Effects of Feeding this Plant Protein on Production and Egg Quality Parameters of Leghorn and Native Layer Strain
Three experiments were conducted to evaluate the nutritional value of bitter vetch. Experiment 1 was conducted to determine the metabolisable energy content of bitter vetch. Sixteen adult Leghorn roosters were used. Forty grams of bitter vetch were precision-fed individually to 12 roosters. In addition, 4 birds were not fed and served as a control treatment in the measurement of metabolic fecal...
[ 4 ] - The Effects of Different Levels of Pomegranate Seed Pulp with Multi-Enzyme on Performance, Egg Quality and Serum Antioxidant in Laying Hens
This study was conducted to investigate the effect of supplementation different levels of pomegranate seed pulp (PSP) on performance and blood parameters in laying hens. A total of 96 layers hens (Hy-line W-36) at 24 week of age were randomly assigned into 4 treatments including 0 (control), 5, 10 and 15% of PSP, with 4 replicates containing 6 layers in each. Results showed no significant effec...
[ 5 ] - Egg Iron Enrichment in Response to Various Levels of Pomegranate by-Product in Laying Hen Diet
The present study was conducted to investigate the effects of different levels of pomegranate by- product (PBP) on performance, egg quality and blood parameters in laying hens. A total of 144 Bobze layer hens from 44 to 56 weeks during 12 weeks were randomly assigned into 4 treatments including 0 (control, corn and soy bean meal), 4, 8 and 12% of PBP, with 4 replicates and 9 layers in each.
