an experiment was conducted to investigate the effects of using different levels of ginger rhizome powder (grp) and turmeric rhizome powder (trp) on production performance and some blood metabolites in laying hens. ninety 103-week old laying hens were divided into 5 treatments in a completely randomized design with 3 replicates and 6 birds in each cage. the birds were fed a corn-soybean meal ba...

the aim of current study was to determine the effects of vitamin c on bone mineral density (in terms of osteoporosis), eggshell quality and investigation of correlation between these factors in laying hens reared under normal condition. one hundred and ninety two 24 - weeks - old laying hens diet was supplemented with 4 levels of vitamin c (0, 250, 500 and 750 mg/kg diet). the experimental desi...

An experiment was conducted to investigate the effects of dietary supplementation of Rhodobacter capsulatus KCTC-2583 on egg-yolk and serum cholesterol, egg production and quality parameters during the late laying periods in hens. A total of 160 Hy-Line Brown layers (54 wk-old) were randomly allotted to 4 treatment groups on the basis of laying performance. Each treatment had 4 replicates with ...

Soybean meal is the main source of protein in laying hens’ diet that generally imported. This study aims to explore yellow mealworm larvae (Tenebrio molitor) “TM”, and curcuma effects on performances, physical nutritional eggs quality. One hundred hens were divided randomly into 4 groups. The first group (Control) received a standard commercial (SCD), while test groups (TM, TP, TM-TP) SCD with ...

Coronary heart disease (CHD) is the leading cause of death in the United States. Elevated levels of plasma total cholesterol (TC), and particularly plasma low density lipoprotein-cholesterol (LDLC), are primary contributing factors to CHD. Dietary plant sterols (phytosterols) have been shown to significantly reduce plasma TC and LDLC in humans, primarily through inhibition of intestinal cholest...

two experiments were conducted to evaluate the nutritional value of purslane powder and its effects on performance, egg quality and reproductive system parameters of laying hens. one hundred and twenty laying hens (leghorn, hy-line w-36) were used in a completely randomized design with four treatments and five replicates. hens received diet supplemented with different levels of purslane powder ...

this experiment was conducted to evaluate the effects of different levels of costmary(tanacetum balsamita)medicinal plant on performance, egg traits, and blood biochemical parameters of laying hens. hundred-eighty of hi-line laying hens (w 36) from 46 until 58 weeks of age were used in a completely randomized design in five treatments and three replicates (12 birds per replicate). the treatment...

This 6-wk study was conducted to determine the effects of probiotic (Enterococcus faecium DSM 7134) supplementation of different energy and nutrient density diets on performance, egg quality, excreta microflora, excreta noxious gas emission, and serum cholesterol concentrations in laying hens. A total of 432 Hy-Line brown layers (40 wk old) were allotted into 4 dietary treatments with 2 levels ...
