Cryopreservation protocols induce partially irreversible damage to mammalian sperm plasma membranes. Previous studies have indicated that adding cholesterol to the plasma membrane, as cholesterol-loaded-cyclodextrins, improves cryosurvival of sperm. Therefore, the purpose of this study was to determine if treating sperm of Markhoz bucks with cholesterol-loaded-cyclodextrins (CLC) (0, 0.75, 1.5,...

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, feed...

in this experiment, a total of 128 hy-line w36 hens at 63 weeks of age were used. the hens were put at random into 4 treatment groups (4 replicates and 32 hens per treatment) and were fed four different diets: three diets with different levels of spirulina (1.5, 2.0 and 2.5%) and one control group based on wheat and soybean meal. all birds were housed in commercial cages, had ad libitum access ...

Straková E., P. Suchý, M. Šugerková, M. Macháček: Positive Effect of Plant-Based Diet on the Performance and Health of Laying Hens. acta vet. Brno 2007, 76: S31-S37. an entirely plant-based feed mixture was prepared to minimize the potential risk of transmitting prion infections through animal feed. It consisted of two protein components (soya extracted meal and lupin seed meal) and was compare...

The aim of the study was to determine whether a diet with an addition black cumin seeds (BCS) can be used in functional egg production. At 8 weeks age, flock 96 female quails divided into 3 groups. control group received their standard feed (0 BCS). offered test groups supplemented BCS amount 20 and 50 g · kg–1, respectively. Dietary supplementation decreased intake improved efficiency. Egg yol...

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 aimed to evaluate the effects of dietary egg yolk phosphatidylcholine (EPC) and soybean (SPC) on obesity mice fed a high-fat diet (HFD). After 60 days intervention, were evaluated by biochemical indices serum lipidomic analysis. EPC SPC markedly reduced total cholesterol, triacylglycerol (TAG) low-density lipoprotein while increased high-density cholesterol. was more effective in red...

Membrane microdomains or lipid/membrane rafts are distinct areas on the plasma membranes, where a specific subset of lipids (e.g. cholesterol, sphingolipids) and proteins (e.g. glycosylphosphatidylinositol-anchored proteins, growth factor receptor/kinases) are getting together and functioning for several aspects of cellular functions. Our recent investigation has revealed that fertilization of ...
