in this study, the effects of culban seed (vicia peregrine l.) on live body weight, feed intake, feed efficiency, egg production, egg quality characteristics, egg yolk fatty acid profiles and yolk cholesterol content in laying hens were investigated. the experiment consists of seven treatment groups with ten replications containing one laying hen in each and for 32 weeks old seventy laying hen ...

Background Low-density lipoproteins (LDL) is known to protect boar sperm during freezing–thawing, but little information is known about the effects of LDL extracted from different avian egg yolks on post-thaw boar semen quality. The purpose of this study was to compare and analyze the effects of LDL at various concentrations and different species on boar sperm quality after freezing–thawing. Ma...

Omega-3 polyunsaturated fatty acids (n-3 PUFAs) enriched eggs are popular for their enrichment of PUFAs, but their freshness and quality are prone to decline with time, particularly if storage conditions are not well maintained. Home storage is the last but a neglected important tach in eggs supply chain, but few studies are available on the egg storage in the home stage. This study aimed to ev...

A method has been developed to isolate cortical granules (CG) free in suspension. It involves the mechanical disruption of the CG from CG lawns (CGL; Dev. Biol. 43:62-74, 1975) and concentration of the CG by low speed centrifugation. The isolated CG are intact and are a relatively pure population as judged by electron microscopy. Granule integrity is confirmed by the fact that isolated intact C...

Salmonella enterica is a major food-borne pathogen of world-wide concern. Sensitive and rapid detection methods to assess product safety before retail distribution are highly desirable. Since Salmonella is most commonly associated with poultry products, an evanescent wave fiber-optic assay was developed to detect Salmonella in shell egg and chicken breast and data were compared with a time-reso...

Diapause is a common biological phenomenon that occurs in many organisms, including fish, insects, and nematodes. In the silkworm (Bombyx mori), diapause generally occurs in the egg stage. Treatment with O₂, HCl, or other compounds can prevent egg diapause. Here, we characterized the transcriptomic responses of newly laid eggs treated with O₂ or HCl. Digital gene expression analysis showed that...

This study aims to analyze the Break-Even Point of Backyard laying hens business in Sidenreng Rappang Regency. research was conducted Bulo Village, backyard farm. from February April 2020. In this used a case study, results are not generalized. The total profit earned by these people's farm is IDR 137,717,244. For price 37,000 eggs, it will reach BEP at 1,617,723/ egg, 1,436,727,272 with egg 88...

to study the effects of post-stripping oocyte ageing at low temperatures on the viability of kutum (rutilus kutum) oocytes, unfertilised eggs of five females were stored in ovarian fluid at temperatures of 4 and 7 degree centigrade for 24 hours post stripping (hps). the stored ova of five female kutum were separately fertilised at 0 (i.e., control eggs fertilised prior to storage), 4, 8, 12, 16...

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)...

The fatty acid compositions of egg yolks subjected to industrial processing treatments, namely, homogenization, pasteurization, drying, and "omega-3-enrichment", were studied. In general, the total contents of C16:0, C18:0, C18:1 n-9, and C18:2 n-6 fatty acids accounted for close to 90% of the total fatty acids. Statistical analysis of the data revealed correlations among the fatty acids; signi...
