Book Description
Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * 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 34 (thesis year 1989) a total of 13,377 theses titles from 26 Canadian and 184 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 34 reports theses submitted in 1989, on occasion, certain univer sities do report theses submitted in previous years but not reported at the time.

Book Description
Six ruminally and duodenally cannulated Angus cross bred cows (680 ± 47.1 kg of initial BW) were utilized in a crossover design to evaluate the effects of method of processing supplemental corn on forage intake, digestive function, metabolizable protein, and ruminal fermentation. Cows were maintained in individual pens (5 x 4 m) and offered hay and corn at 0700. Hay was offered to ensure ad libitum intake and 10% feed refusal daily. Corn grain was supplemented at 0.2% of BW (as fed basis) and placed directly into the rumen through the ruminal cannula. Bluestem hay (Bothriochloa ischaemum; 5.7% CP, 69.4% NDF, and 11.49% ash, DM basis) was offered after corn supplementation. Treatments consisted of 1) ground corn (GC) and steam-flaked corn (SF). Experiment consisted of 2 experimental periods in which 9 d were for adaptation and 4 for rumen fluid, duodenal, and fecal samples collection. Hay DM intake and total DM intake were greater (P = 0.04) for GC than for SF. Also, intake of CP (P = 0.02), NDF (P = 0.04) were greater and starch intake (P = 0.01) was lower for GC than SF. The flow of nutrients to the duodenum (P ≥ 0.11) was not affected by corn processing method with the exception of starch which was greater (P = 0.01) for GC than SF, and therefore starch ruminal digestion was greater (P = 0.01) for SF. Microbial efficiency was not affected (P = 0.11) by corn processing method. Total tract digestion of DM (P = 0.007), OM (P = 0.09) and NDF (P = 0.11) tended to be lower, while total tract digestion of starch (P = 0.02) was greater for SF than GC. Ruminal pH, total VFA production, and ammonia concentration were not affected (P ≥ 0.18) by corn processing method. However, the proportion of acetate (P = 0.01; 74.4, and 71.7 ± 0.77 mol/100 moles) was greater, propionate (P = 0.06; 14.8, and 17.2 ± 0.81 mol/100 moles), and butyrate (P = 0.05; 7.2, and 8.3 ± 0.32 mol/100 moles) were lower for GC than for SF. Supplemental SF decreased low-quality forage intake without negatively impacting microbial protein and feed protein supply to the duodenum.
