Diet, nutrition, and foraging strategies of canvasbacks (Aythya valisineria) and redheads (A. americana) were studied by collecting actively feeding birds throughout the reproductive season in 1980 and 1981; samples of available foods were taken each time a bird was collected. Nutrient composition of the aggregate diet was determined for each...
Eight experiments, two with poults and six with chicks, were
undertaken to determine the requirement for supplemental folic acid
as related to protein level and major protein source. Protein levels
for chicks and poults were 21, and 28 or 28 and 32%, respectively.
Major protein sources were soybean meal, fish...
An experiment was conducted during the period November 1967
to November 1968 at Oregon State University (OSU) and the Umatilla
Branch Experiment Station (BES) at Hermiston, two trials at each
location, to answer several questions: (1) could comparable rations
for swine be formulated by a computer on a least-cost basis;...
An experiment was conducted with 48 Yorkshire x Berkshire
crossbred barrows to evaluate the influence of varying Calorie: protein ratios in high-fat rations on performance and carcass quality
of growing-finishing swine. Pigs were individually fed rations containing
three levels of fat (lard): 0, 15 and 30 percent. Each fat
level...
