Tb122: Comparison Of Alpha- And Beta-Carotene Content Of Supermarket Vs Roadside Stand Produce In Maine, R. J. Bushway, A, Yang, A. M. Yamani
Tb122: Comparison Of Alpha- And Beta-Carotene Content Of Supermarket Vs Roadside Stand Produce In Maine, R. J. Bushway, A, Yang, A. M. Yamani
Technical Bulletins
A study was conducted to determine the alpha- and beta-carotene content of supermarket vs roadside stand produce using high-performance liquid chromatography (HPLC). The fruits and vegetables were obtained from a major local supermarket chain and three roadside stands in Dixmont, Etna and Charleston, ME. Thirteen vegetables and one fruit were sampled during a ten-week period between July and September of 1985. Significant differences at the 0.05 level were observed between supermarket and roadside stand produce for only Swiss chard and green peppers with roadside stands having higher beta-carotene levels in both instances. Alpha-carotene was shown to be nonsignificant among sources …
Tb120: Alternative Assessment Of Individual Dietary Intake--A Pilot Study, Paula A. Quatromoni, Richard A. Cook
Tb120: Alternative Assessment Of Individual Dietary Intake--A Pilot Study, Paula A. Quatromoni, Richard A. Cook
Technical Bulletins
In an initial effort to devise a rapid assessment alternative that would provide a reliable estimate of an individual's usual dietary pattern, a Predicted Food List (estimated, abbreviated food frequency), an Actual Food List (recorded, truncated food frequency), and a Typical Diet Day (foods perceived as commonly consumed in a 24-hour period) were compared with a 75-day food record. Overall, the Predicted Food List appeared to be the best tool for depicting an individual's usual food intake. It was concluded that a shortened list of food items characterizing an individual's normal nutrient intake level may be a useful instrument allowing …
Tb42: The Mycotoxic Effects Of Fungi Isolated From Poultry Feed Ingredients: The Response Of Ducklings And Performance Of Commercial Broiler Chickens Fed Experimentally Infected Corn Diets, Elizabeth S. Barden, H. L. Chute, D. C. O'Meara, Hilda T. Wheelwright
Tb42: The Mycotoxic Effects Of Fungi Isolated From Poultry Feed Ingredients: The Response Of Ducklings And Performance Of Commercial Broiler Chickens Fed Experimentally Infected Corn Diets, Elizabeth S. Barden, H. L. Chute, D. C. O'Meara, Hilda T. Wheelwright
Technical Bulletins
The present work, planned to investigate the possibility of mycotoxins occurring in feed ingredients fed to poultry in Maine, was designed with the following objectives: (1) to isolate fungi from poultry feed ingredients; (2) to grow the m separately on corn (the carbohydrate source of poultry rations) for later mixing into the diets; (3) to test the variously infected lots of this corn substrate for mycotoxicity by feeding ducklings, a bioindicator for toxins; (4) to determine the effects of aflatoxin and other mycotoxins from feed ingredients, on the performance of commercial broiler chickens; and (5) to appraise this response as …
Tb38: Utilization Of Amino Acids From Protein By The Growing Rat: Efficiency Of Carcass Protein Formation, Frederick H. Radke, Herman Dehaas, Richard A. Cook
Tb38: Utilization Of Amino Acids From Protein By The Growing Rat: Efficiency Of Carcass Protein Formation, Frederick H. Radke, Herman Dehaas, Richard A. Cook
Technical Bulletins
Ten experiment stations in the Northeast have cooperated in investigating three sources of amino acids (pure amino acids, milk protein and wheat gluten) at two levels (1.2% and 1.6% dietary nitrogen) with different subjects (humans, rats, pigs and protozoa) under different conditions (growth, maintenance and stress) in order to study availability of amino acids in protein. The publication describes the effect of the three nitrogen sources containing equal amounts of essential amino acids and nitrogen on the growth of rats over two and four weeks.
Tb40: Effect Of Dietary Changes On The Tissue Composition Of Rats, Frederick H. Radke, Herman Dehaas, Eileen K. Gabrielson
Tb40: Effect Of Dietary Changes On The Tissue Composition Of Rats, Frederick H. Radke, Herman Dehaas, Eileen K. Gabrielson
Technical Bulletins
The following experiments were done to study the effects of both long-term and day-by-day dietary changes of fat and protein on tissue fat and serum cholesterol levels.
