Assessing the phosphorus and potassium balances in Oregon's dairies

Creator:: Higgs, Kathryn N.
Abstract:: A field study was conducted to assess phosphorus (P) and potassium (K) concentrations of both lactating and dry cow diets on Oregon's dairies. Thirty-seven dairy farms, located in western Oregon, were grouped according to geographic region, valley (V) or coast (C), and herd size, small (S) or large (L). Farms...

Feed management : a tool for balancing nutrients on dairies and other livestock operations

Creator:: Gamroth, Michael J., Downing, Troy (Troy Woerner), French, Patrick D., 1969-, and Oregon State University. Extension Service
Abstract:: Many studies have shown that dairies consistently overfeed nutrients such as phosphorus (P) and potassium (K). This practice is expensive and potentially damaging to the environment and to animal health. This publication suggests ways to improve feed management and thus avoid overfeeding P and K. Proper ration balancing is good...

Identification of potential copper and molybdenum livestock nutrition problems with forage analysis

Creator:: Kresge, Paul Owen
Abstract:: Copper deficiency and Mo-induced Cu deficiency are nutrition problems of ruminant livestock in the Burns and Klamath Falls area of Oregon. Chemical analysis of plant and soil samples was used to survey Cu and Mo levels in forage in these areas. The objectives were to assess the possibility of animal...

Potential new protein sources for monogastric animals

Creator:: Kinzell, John Harold
Abstract:: A series of four trials was conducted to evaluate activated sewage sludge (AcSS) as a protein source. In the first trial the protein efficiency ratio (PER) of sun-dried and auto-claved, sun-dried AcSS was measured with rats. Growth of AcSS-fed rats was extremely poor as compared to those rats fed casein,...

Effects of dietary selenium ad vitamin E on he gray-tailed vole

Creator:: Pond, Finn Richard
Abstract:: The gray-tailed vole (Microtus canicaudus) demonstrated a requirement for selenium and vitamin E. Animals deficient in both nutrients suffered from liver necrosis and an unthrifty condition characterized by inappetence, profuse diarrhea, and swollen eyes. Vitamin E appeared less effective than selenium as a prophylaxis against this syndrome. Total body weights,...

Relationship of dietary crude protein to factors in uterine secretions and plasma in high producing postpartum dairy cows

Creator:: Jordan, Ellen Rae
Abstract:: Eighteen multiparous, high producing (7,836 kg 4% FCM) Holstein dairy cows were assigned randomly to iso- . caloric rations containing either 12 or 23% crude protein (CP) on day 40 postpartum. After a 10-day adaptation period, uterine secretion and blood samples were collected on the day of estrus (day 0-1),...
