Book Description
Eight Angus cross-bred cows (669 ± 23.2 kg of BW) fitted with duodenal and ruminal cannulas grazing winter wheat pasture (WWP) were used in a split-plot design to evaluate the effects of monensin supplementation and WWP stage of maturity on forage intake, digestive function, metabolizable protein, and ruminal fermentation. Supplemental treatment was the main plot, and stage of maturity was the subplot. Two levels of monensin supplementation: 1) Control (CON; 1.0 kgcow−1d−1 of wheat middling only), and 2) monensin (MON; CON plus 200 mg of monensin); and two stages of WWP maturity: 2) mid-March (MAR; March 13 to March 26; vegetative stage), and 2) early April) (APR; March 27 to April 8; heading stage) of 2017 were compared in a 2 x 2 factorial arrangement of treatments. Cows grazed in a single wheat pasture with supplements deposited directly into their rumens through their rumen cannula at 0700 daily. Monensin supplementation did not affect forage intake (P = 0.64), nutrient flow to duodenum (P ≥ 0.47) or total tract digestion expressed as kg/d (P > 0.45). Although, OM and CP flowing to the duodenum were not affected by monensin supplementation (P ≥ 0.53), microbial OM and microbial CP decreased (P = 0.03) with monensin supplementation. As stage of maturity of WWP advanced, forage intake (P = 0.02), ruminal digestibility of DM and OM (P ≤ 0.05) and total tract digestion expressed as kg/d (P = 0.01) decreased. Also, total duodenal CP (P = 0.01), microbial protein (P = 0.01), and feed protein (bypass protein; P = 0.03) flow decreased with advancing WWP stage of maturity. Monensin supplementation increased (P = 0.01) propionate (18.38, and 20.79 ± 0.55 mol/100 mol), and decreased (P = 0.01) the acetate: propionate ratio (3.26, and 2.73 ± 0.13). Ruminal pH (6.03 and 6.31 ± 0.08), acetate (54.6 and 58.3 ± 0.98 mol/100 mol), and acetate propionate ratio (2.52, and 3.48 ± 0.13) increased (P ≤ 0.04), and propionate (21.9, and 17.3 ± 0.56 mol/100 mol) decreased (P ≤ 0.05) with advancing WWP stage of maturity. Results suggest that monensin increases propionate without affecting forage intake, digestibility or metabolizable protein of cattle grazing WWP.

Masters Theses in the Pure and Applied Sciences

Book Description
Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Oata Analysis and Synthesis (CINOAS) * at Purdue. University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volumes were handled by an interna tional publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 33 (thesis year 1988) a total of 13,273 theses titles from 23 Canadian and 1 85 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this important annual reference work. While Volume 33 reports theses submitted in 1988, on occasion, certain univer sities do report theses submitted in previous years but not reported at the time.

Book Description
Biotechnology and Nutrition documents the proceedings of the Third International Symposium Biotechnology and Nutrition jointly sponsored by the University of Maryland, the United States Department of Agriculture, and E. I. du Pont de Nemours & Co. The symposium was organized to provide a forum for nutritionists, molecular biologists, animal and plant biochemists, food scientists, policymakers, and others who will influence the improvement of nutrition through the application of biotechnology. The contributions made by researchers at the symposium are organized into five parts. Part I provides a broad consideration of human nutrition and the ability of biotechnology to improve nutrition. Part II presents studies on carbohydrate nutrition, including industry trends and nutritional issues for food uses of starch and human physiological responses to dietary fiber. Part III focuses on proteins, including studies on improving the nutritional quality of legume seed proteins and increasing the lysine content of maize. The studies in Part IV deal with vitamins and minerals, such as genetic improvement of vegetable carotene content and iron uptake and translocation in plants. Part V examines molecular approaches in the modification and production of edible oils.
