The objectives of this study were to investigate the effects of different dietary sources of unsaturated fatty acids (fish oil (FO) and/or linseed oil (LO)) on laying performance, egg yolk fatty acid composition, ovarian follicular development, antioxidative properties, immune response and tibial bone characteristics in aged laying hens. A total of 100 Hisex Brown hens at 56 weeks of age were h...
Egg yolk is the most commonly used cryoprotective agent for sperm cryopreservation of several species.The objective of this experiment was to compare the effectiveness of egg yolk from four avian species(domestic chicken, duck, turkey and pigeon) on sperm quality following cryopreservation of the ram semen.Ejaculates were collected, using an electroejaculator, from six fertile rams. Samples wer...
One of the main problems of multiple-trait genetic evaluation in poultry breeding is high computing costs. Principal components analysis (PCA) is a method for reducing the number of traits in correlated trait analysis. The aim of the present study was to determine the most effective principal components (PCs) of internal egg quality and some performance traits of Azarbayjan native chickens. ...
The egg quality is one of the most important economic factors for layers that are crucial for hatchability and marketing. Given the low number of egg quality traits records, one of the approaches in estimating phenotypic and genetic parameters is multi trait analysis. The aim of this study was to estimate the phenotypic and genetic parameters of west Azerbaijan native hens egg quality traits by...
The present study was an attempt to raise hen egg yolk Ig (IgY) simultaneously directed against Salmonella Enteritidis (SE) and Salmonella Typhimurium (ST) in the same egg yolk. The immunopotentiating effect of 2 different adjuvants -- Freund's adjuvants (FA) and immunostimulating complexes matrix (IM) -- on antibody response was also evaluated. Bacterial outer membrane proteins (OMP) were sele...
Hen egg yolk is normally used as a cryoprotective agent in semen freezing extenders, but its use has sanitary and practical disadvantages. Moreover the protection afforded by egg yolk has not yet been completely elucidated. The objective of this study was to compare the egg yolk plasma fraction to whole egg yolk in stallion freezing extender. Plasma contains mainly Low Density Lipoproteins (LDL...
This study was conducted to assess the physical and morphological characteristics of fresh, pre-freeze and post-thaw black Bengal buck (Capra hircus) semen processed in Tris-egg yolk-citrate-fructose-glycerol (TEYCFG) extender containing 4 different concentrations (2.5, 5, 7.5 and 10%) of egg-yolk. Ejaculates were collected once a week for eight weeks from six mature bucks (48 ejaculates) using...
During the semen cryopreservation, various biochemical and anatomical compartments in the sperm cells may be altered. Therefore, the most important part of sperm-freezing protocols is use of cryoprotectant agents in freezing. The aim of this study was to determine the effect of different dosage of egg yolk (15, 20 and 25 %) as natural a cryoprotectant plus different dosage of sodium dodecyl sul...
cultured under serum-free conditions for the mass production of human MoAbs,S+ Howcver, the Ig productivity ofhuman-human hybridomas has been lewer than that of mouse-mouse hybridornas, especially in serum-t'ree media.6' To enhance the Ig productivity of human-human hybridomas under serum-free conditions, we screened the immunoglobulin production stimulating factor (IPSF), and have found cellul...
