Studies on Egg Yolk Cholesterol

Egg Yolk Cholesterol of Hens Fed Barley Malt Rootlets

This study aimed to decrease the cholesterol content of egg yolk of laying hens through inclusion of barley malt rootlets in the diets. Forty-two, 54-week-old, Lohman laying hens were fed for a 12 weeks laying period on 3 iso-caloric and iso-nitrogenous diets contained 0 (control), 25.5 or 51.1g barley malt rootlets/kg. Inclusion of barley malt rootlets at 25.5 or 51.1g/kg diet significantly de...

Studies on the Egg Yolk Agglutinating Factors in Boar Semen

The author and his co-workers have found out that, when the diluents including egg yolk for freezing of boar spermatozoa were used, egg yolk agglutinated immediately after the dilution and most of the spermatozoa were enclosed into the agglutinated masses and their motility was drastically suppressed. On the other hand, by using skim milk-diluent widely used for storing liquid boar semen at 15°...

Analysis of cholesterol oxides in egg yolk and turkey meat.

A study was conducted to develop a solvent system that will clean egg yolk samples and concentrate cholesterol oxides effectively before analysis. Cholesterol oxide standards or lipid samples (0.2 g) loaded onto a silicic column were washed with a portion of Solvent I (hexane/diethyl ether, 9:1, vol/vol) and then with Solvent II. Four different Solvent II preparations (Solvent IIa, hexane:ethyl...
