Objective: The objective of the current study was to investigate effects dietary hatchery by-products (HBPs) as a replacement fish meal (FM) on growth performance, relative organ weight, plasma measurements, immune index, meat quality, and tibia characteristics broiler chickens. Methods: A total 720 chickens (3 d age) were randomly allotted 1 9 treatments with 8 replicates. Each replicate consisted 5 male female birds. basal diet formulated contain 5.0% commercial FM, whereas eight treatment...

Background. Despite the beneficial effects of alagebrium (ALA), a putative advanced glycation end-product (AGE) breaker, on diabetic nephropathy, its renoprotective mechanisms are incompletely understood. Since oxidative stress exacerbates renal injury through interaction with AGE, present study examined antioxidative property ALA in db/db mice, mesangial cells cultured under high glucose or H2O2 and test tube.

The objective of the current experiment was to investigate effect dietary magnesium (Mg) and δ-aminolevulinic acid (ALA) supplementation on productive performance egg quality in laying hens. present performed using a completely randomized design with 2 × factorial arrangements including levels supplemental Mg (0 0.12%) ALA 0.25%) diets. A total 192 43-wk-old Hy-Line Brown hens were allotted 1 4 treatments 6 replicates. Each replicate consisted consecutive cages per cage. Treatment diets fed...

The objective of the present experiment was to investigate effect dietary palm kernel meal (PKM) and β-xylanase supplementation on productive performance, egg quality, fatty liver incidence, excreta characteristics in laying hens. A total 320 Hy-Line Brown hens (33 weeks age) were allotted 1 4 treatments with 8 replicates a feeding trial. Each replicate consisted 10 consecutive cages hen per cage. corn-soybean meal-based control diet prepared. Additional prepared by including 10% PKM partial...

The objective of the present experiment was to determine ME concentrations and amino acid (AA) digestibility in various hatchery byproducts (HBPs) for broiler chickens. In 1, a total forty 60-day-old female chickens were allotted 1 5 dietary treatments with 8 replicates used measure HBPs. basal diet prepared contain corn, soybean meal, corn oil, other non-energy ingredients. Additional 4 experimental diets 10% infertile eggs (IFE), unhatched (UHE), low-grade or dead chicks (LDC), mixture...
