The Site Of Absorption Of Xanthophylls And Factors Affecting Pigmentation Of Chickens, Egg Yolks, And Products Made From Egg Yolks, Lloyd Henry Littlefield
The Site Of Absorption Of Xanthophylls And Factors Affecting Pigmentation Of Chickens, Egg Yolks, And Products Made From Egg Yolks, Lloyd Henry Littlefield
Doctoral Dissertations
A total of four experiments were conducted to determine the location of the site of absorption of xanthophylls, to determine the relationship of egg yolk color produced by various feed xanthophylls to the color of mayonnaise, and to study the effect of the level of dietary cow manure, age, ambient temperature and feed consumption of xanthophyll pigmentation of hens and egg yolks.
Increases in the level of blood xanthophylls and visual pigmentation of xanthophyll depleted hens were used to measure the absorption of xanthophylls. Surgical removal of either the duodenum, jejunum, ileum or large intestine resulted in a slight but …
The Influence Of Dietary Sulfate On The Excretion Of 35S-Cysteine Sulfur As 35S-Taurine Sulfur By The Rat, Betty Ann Whittle
The Influence Of Dietary Sulfate On The Excretion Of 35S-Cysteine Sulfur As 35S-Taurine Sulfur By The Rat, Betty Ann Whittle
Doctoral Dissertations
The relationship of dietary sulfate to the efficiency of feed utilization, excretion of 35S-cysteine sulfur as 35S-taurine sulfur, and sulfation of lung tissue by the rat was investigated.
The feed efficiencies of animals fed diets from weaning that contained 0.10 per cent of inorganic sulfate and 0.47 per cent of organic sulfur as sulfate were significantly higher at the end of a six-week feeding period than were those of littermates fed diets that contained higher or lower levels of inorganic sulfate but comparable levels of total sulfur as sulfate. These findings showed that equivalent levels of sulfur as …
Relation Of Phospholipids To Selected Tissue Components In Light And Dark Portions Of Porcine Semitendinosus Muscle, Marian Dianne Ruff
Relation Of Phospholipids To Selected Tissue Components In Light And Dark Portions Of Porcine Semitendinosus Muscle, Marian Dianne Ruff
Doctoral Dissertations
The semitendinosus of pork contains a light and a dark portion that have physicochemical properties similar to those of uniformly white and red muscles, respectively. Although the two portions differ in metabolic activity they function as one muscle. The purpose of this study was to investigate the relation of phospholipid concentration to predominant fiber of the two portions of the porcine semitendinosus. The light and dark portions of the porcine semitendinosus were selected in order to minimize the possible effect of exercise on phospholipid content.
Phospholipids of the light and dark tissue of the porcine semitendinosus were studied in relation …
The Use Of Varying Levels Of Urea In Concentrates Fed To Dairy Cattle, John Roland Plummer
The Use Of Varying Levels Of Urea In Concentrates Fed To Dairy Cattle, John Roland Plummer
Doctoral Dissertations
Five experiments were conducted to investigate the use of concentrates that contained varying levels of urea for dairy cattle fed corn silage as the only forage.
Three experiments were conducted using 84 Holstein cows. Twenty-seven cows were used in Experiment I to compare a concentrate supplemented with soybean meal with a concentrate in which 2 percent urea (by weight) replaced a portion of the soybean meal on an equal nitrogen basis. Effects of frequency of feeding of concentrates containing urea were also studied. Results indicated that ration intake, body weight changes, milk production, milk protein, and milk SNF were not …
