A series of four animal experiments utilizing 129 pigs
and associated laboratory studies was conducted to study the causes
of the lowered performance on high barley rations fed to swine. Previous
work at this Station has shown barley to have a value of 80-85
percent of corn for swine, and...
Seven in vitro trials were conducted to compare the effects of
soaking annual ryegrass straw in solutions of sodium hydroxide (Na₄OH),
potassium hydroxide (KOH), ammonium hydroxide (NH₄OH), or sodium
formate (NaCHO₂) at varying levels. Dry matter digestibility (DDM)
was the criterion used to measure treatment response. A 3 x 3...
Studies were conducted with Indian River "Hybro" broiler chicks
and Oregon Agricultural Experiment Station dwarf and normal White
Leghorn hens to improve the utilization of white western wheat. Chick
studies were primarily concerned with characterizing the growth
inducing properties of an antibiotic fermentation residue (Vigofac)
which had shown a greater...
Observations were made on silage pH, chemical composition and 24hr in vitro dry matter digestion (IVDMD) to evaluate effects of various additives ensiled with annual ryegrass straw. Additives were compared in factorial designed trials utilizing .95 1 glass jar silos. Selection of additives used in each subsequent trial was based...
Five experiments were conducted to investigate the
effect of dietary fish meal on the incidence of Sudden Death
Syndrome (SDS) in broiler chickens. Growth, feed
efficiency, total mortality and mortality due to SDS were
evaluated. Necropsy examination was performed on broilers
suspected of dying from SDS. Liver lipid and fatty...
