Lupine seeds are a valuable nutritive source for animal feeding, but poultry nutrition, the content in crude fiber and non-starch polysaccharides (NSP) have an antinutritional factor. The aim of this research was to highlight effect partial soybean meal replacement with L. albus enzyme addition laying quail diets on productive performance, digestion, blood biochemical indices egg quality. A tot...

In two experiments, the effects of dietary fat and breeder hen age on relative yolk sac weight (RYSW) and total serum cholesterol (CHOL), high (HDLC) and low (LDLC) density lipoprotein cholesterol, triglycerides (TRI), and glucose (GLU) were monitored in broiler embryos and chicks. In Experiment 1, embryos at 18 d of incubation and chicks at hatch were sampled from eggs laid by breeder hens at ...

Apolipoprotein (apo) B, the principal structural component necessary for the synthesis and secretion of triglyceride-rich lipoproteins by the intestine and liver, is highly expressed in the yolk sac visceral endoderm of mammals, although its function in this tissue has been hitherto unclear. Disruption of the apoB gene in mice results in embryonic lethality (approximately 9.5 - 10.5 d). Here we...

This present study was conducted to evaluate the effects of dietary inclusion of 4, 8 and 12 g kg(-1) phytogenic feed additives mixture on performance, egg quality, ovary parameters, serum biochemical parameters and yolk trimethylamine level in laying hens. The results of experiment have shown that egg weight was increased by supplementation of 12 g kg(-1) feed additive whereas egg production, ...

BACKGROUND There is completely no report about both hen egg anti-lipase immunoglobulin yolk (IgY) and its anti-obesity action. Thus, we tried to isolate and characterize a novel anti-lipase immunoglobulin from hen egg yolk. Moreover, we investigated whether hen egg yolk anti-lipase IgY inhibits pancreatic lipase activity in vitro, and examined its ability to prevent obesity in a murine high fat...

The quality of eggs laid by 2 hybrid and 2 Italian dual-purpose genotypes of hens reared under organic farming system was studied. Hens belonging to Hy-Line Brown (brown eggshell, HLB), Hy-Line White (white eggshell, HLW), Ermellinata di Rovigo (brown eggshell, E), and Robusta maculata (brown eggshell, R) genotypes were reared from 24 to 43 wk of age. The trial was carried out from July to Dece...

The aim of this study was to investigate the effect different age and plumage color on egg quality traits cholesterol levels, in addition which can be used for weight prediction Japanese quails. eggs obtained from 23-week-old original colored Jumbo quails, 39-week-old quails; 40, 20 were respectively as research material. In terms difference, when quails compared yolk weight, height, diameter h...

This study determined whether supplementing the diet of laying hens in final third with vitamin D improves bird health and egg performance quality. The were separated into four groups six repetitions each five animals per repetition to test three doses supplementation (50, 100, 150 mg/kg). had no effect on performance; however, when we individually evaluated repetition, found that birds T100 T1...

Lipids are an important nutritional component of the avian egg. A review of the literature was completed to determine the fatty acid compositions in egg yolk from some avian species. Additionally, the nutritional influence of lipid and lipoprotein content on the plasma of male participants during 30-day feeding was discussed. The ostrich eggs had the highest unsaturated fatty acid and the lowes...

This study aimed to investigate the effects of sumac fruit powder (SFP; Rhus coriaria L.) supplementation on productive performance, egg quality traits and serum biochemical parameters in old laying hens. One-hundred-twenty, 54 weeks Hy-line W36 strain-laying hens were assigned three treatments, five replicates eight per replicate a completely randomised design. Experimental diets included: (1)...
