    A suitable method of fluorimetric determination of riboflavin was developed, and riboflavin in various poultry feeding stuffs was determined by its use. Riboflavin was determined in fodder plants, vegetable refuse and wild plants. The influence of seasonal changes and of different stages of growth on the riboflavin content in fodder plants was investigated. Summer-grown plants contain more riboflavin than those grown in the rainy winter season. The riboflavin content of the plants declines in the course of their growth.

    Influence of an intake of the riboflavin that exerts upon osteogenesis in this research, was examined by a nutritional methods. It search the condition of femur in rats they reared and given three type riboflavin dosage, namely, sufficient riboflavin, few deficient riboflavin and administered sufficient after few deficient riboflavin. As a result, an influence of riboflavin dosage was not recognized about each of the body weight, food intake, and weight and length of femur. In other words, a deficiency symptom was not observed seemingly in the rat that given riboflavin deficiency diet. Also, the calcium contents in the femur decreased significantly by the deficiency of riboflavin. And, the low value was shown the even in the rat that administered sufficient fibroflavin later. Furthermore, even breaking force of the femur decreased by the deficiency of riboflavin.

    Did you know that mushrooms are a good source of riboflavin? Riboflavin is one of the B vitamins, also known as vitamin B2. We need riboflavin to use the carbohydrates, fats, and proteins in the foods we eat. Riboflavin helps us use these nutrients for energy in our bodies and additionally functions as an antioxidant. Riboflavin also is needed to properly use the vitamins niacin, folate, and vitamin B6. For more facts about riboflavin, check out this revised 2-page fact sheet written by R. Elaine Turner and Wendy J. Dahl, and published by the UF Department of Family, Youth and Community Sciences, April 2012. FCS8668/FY211: Facts about Riboflavin (ufl.edu)

    Objective To investigate the riboflavin status of military personnel in heavy labor units, so as to provide the basis for revising the standard of recommended riboflavin intake. Methods Eleven units were selected from different regions. Dietary survey, physical check and 4 h-riboflavin urinary load test were used to evaluate the riboflavin status. Results Dietary riboflavin intake among different units ranged from 1.0 mg to 1.7 mg. Based on 4 h-riboflavin urinary load test, most of the subjects were in insufficient or deficient status while a small number of the subjects were in normal status. Eighteen out of 317 subjects (5.7%) were found to have the signs of riboflavin deficiency. It was calculated that recommended riboflavin intake was 1.8 mg for prevention of riboflavin deficiency. Conclusion The recommended riboflavin intake is 1.8 mg for prevention of riboflavin deficiency in heavy labor units. However, the recommended riboflavin intake for adequacy or sufficiency is remained to be further investigated.

    THE importance of riboflavin, also called vitamin B2 or vitamin G, in poultry feed is quite generally recognized. Numerous studies have been made concerning the relationship of riboflavin to hatchability, chick growth, and the prevention of curled-toe paralysis. The effect of riboflavin intake on the content of eggs has not been studied extensively and particularly since improved methods of analyses have become available. Eggs are one of the good sources of riboflavin in the human diet and the relationship of the amount of riboflavin in poultry feeds to the content in eggs needs further study. Ellis, Miller, Titus, and Byerly (1933) noted that the riboflavin content of the diet influenced the content of the eggs, which was further observed by Heiman (1935). A more complete study to show this effect was made by Norris and Bauernfeind (1940) in which they used groups of hens fed different levels of riboflavin. Their . . .

    Agriculture is an important component of the Iowa economy. When considered in combination with Iowa's food manufacturing and Iowa's industries that specifically produce agricultural inputs, the broader agriculture and agriculture-related manufacturing sectors explain a substantial fraction of the state's jobs and labor incomes. If those industries are analyzed in terms of their contributions towards final demand sales (the preponderance of which are exports from Iowa), all of the jobs linked to those final demand sales can be quantified. By doing so, it is possible to estimate the total number of jobs in Iowa that are directly or indirectly linked to agriculture and agriculture related manufacturing.
