“…The following year Sullivan et al (1956) noted that crude fiber was inadequate as an estimate of carbohydrate availability and suggested the use of cellulose and lignin. Likewise, nutritive value was presented in two 1955 articles in the Journal of Animal Science and expressed as proximate analyses (Fontenot et al, 1955; Long et al, 1955). Three articles appeared in a similar form in 1956 (Erwin et al, 1956; Lloyd et al, 1956; Watkins and Kearns, 1956).…”

Division C‐6 was established in 2000, but members associated with forages and grazinglands have been active in the Crop Science Society of America (CSSA) since its inception; 21 have served as President and many authored textbooks and comprehensive reference works. Complex forage and pasture mixtures were common in 1955, but shifted to monocultures in the 1960s and 1970s. Mixtures returned in the 1980s as N prices increased, broader values of legumes became known, nutritive value was better understood, and environmental issues increased. Alfalfa (Medicago sativa L.) for dairy production had strong leadership from the private sector in seed production and breeding. Tall fescue (Festuca arundinacea Schreb.) was well‐adapted, conserved soil, and extended grazing in the transition zone to increase beef cow–calf production. Bermudagrass [Cynodon dactylon (L.) Pers.] benefited from vegetative propagation, conserved soil, and was improved for adaptation, yield, and nutritive value. Yield advancements, except for a few species, have been discouraging. Management benefited from advances in disease resistance, methods for assessing nutritive value, and understanding the role of endophytic fungi. Modest increases in nutritive value, coupled with improved pasture management, have increased animal performance. Emerging interests include biomass, carbon sequestration, and roles of biodiversity. Molecular techniques offer potential to better understand the plants and make genetic progress.

“…If this is a criterion of the metabolic activity of this tissue, these observations suggest, irrespective of the gross observation noted above, that metabolic activity of the rumen epithelium is not affected by physical form of feed. Long et al (1955) and Blaxter et al (1955) reported that grinding and pelleting long hay rations lowered ration digestibility. The latter author reported an accelerated passage of feed through the gastro intestinal tract when the ration was ground and pelleted.…”

“…Lack of a benefit associated with feed processing for finishing feedlot cattle, however, differs greatly from benefits associated with pelleting finishing feedlot lamb diets. Long et al (1955) reported increased DMD of pelleted complete diets fed to finishing lambs compared to ground diets of identical ingredient composition. reported no effect of feeding pure pelleted alfalfa hay on OMD of finishing lambs when compared to chopped alfalfa hay.…”

Loop, and Laurel Shires, for their time and assistance in the feed mill. I must also express my thankfulness to Tammy Webster and Sarah Beamer for their cooperation and assistance. A sincere thank you also goes out to the West Virginia University Animal and Nutritional Sciences office support staff for the seemingly endless amount of assistance that you have provided throughout the past few years. I would also like to thank Mrs. Jo Gulley, as well as the entire Division of Animal Feeds at the U.S. Food and Drug Administration's Center for Veterinary Medicine for giving me the opportunity to begin a career while subsequently completing my degree. I would like to express my deepest gratitude to my family; my parents, John and Carolyn Smith, my siblings, Kimberly Huffman and Ethan Smith, and my grandparents, Hazel and Bill McAmis, and Margaret and Dean Smith, for their endless support, patience, and encouragement.
