The Collection and Summarization of Feed Composition Data. II. A Proposed Source Form for Collection of Feed Composition Data¹

Utah State University, Logan, and Macdonald College (McGill University), Province of Quebec, Canada

Abstract

A cooperative feed composition project between the United States and Canada is being conducted to compile nutrient composition data for feed manufacturers, students and research workers. A source form has been designed for use in collecting and summarizing these data for all classes of feeds. The form requests the following identifying and descriptive information: reporting laboratory, origin of sample as country, state, date collected, literature reference, feed name including components, as origin or parent material; species, variety or kind; the part actually eaten; the process(es) to which the feed was subjected; stage of maturity; cutting or crop; and grade or quality designation. Information is also desired about digestibility trial data, the animals from which the data were collected; type of feeding, percent of test ingredient in ration; length of collection period; amount of feed consumed and basis for calculating level of feeding. Space is provided for data about proximate analyses, carbohydrates, lignin, fatty acids, gross, digestible, metabolizable, and net energy, total digestible nutrients,16 minerals, 17 vitamins and 21 amino acids. Preferred units of measure for these are percent, kilocalories per kilogram, and milligrams per kilogram. These source forms have blocks for codes, so that the data may be punched into IBM cards for machine processing.
