Measurments Of Haptoglobin, Serum Amyloid A, Fibrinogen, And Leukocytes To Evaluate Stress In Organically Managed, Pasture-Fed And Conventional Managed, Totally Mixed Ration-Fed Jersey Cattle., Dorothy Ann Perkins
Master's Theses and Capstones
In cattle sub-acute inflammatory disorders are difficult to assess because visual symptoms of diseases are not easily detectable with large numbers of dairy cattle in loose housing. In addition, inflammation is not always followed by leukocytosis in cattle, which makes the use of common blood tests like total white blood cell counts less reliable as a diagnostic tool. More sensitive and objective methods are needed to evaluate health status. Research has been focused on the use of acute phase proteins (APPs) to diagnose acute and chronic illness in cattle, because acute phase proteins respond very quickly when an inflammation event …
Effects Of Ground Flaxseed Supplementation On Animal Production And Milk Fatty Acid Profile In Organically-Certified Lactating Jerseys During The Grazing Season, Brianna Jeanette Isenberg
Effects Of Ground Flaxseed Supplementation On Animal Production And Milk Fatty Acid Profile In Organically-Certified Lactating Jerseys During The Grazing Season, Brianna Jeanette Isenberg
Master's Theses and Capstones
The objective of this thesis was to evaluate the effects of supplementing a pasture-based diet with ground flaxseed (GFLAX) on milk production and composition, blood parameters, digestibility, ruminal characteristics, nitrogen excretion, methane (CH4) and carbon dioxide (CO2) production, and income over feed cost (IOFC). Twenty organically-certified lactating Jerseys were blocked by milk production and days in milk (DIM) and randomly assigned to 1 of 2 treatments: 1) control (soybean meal and ground corn grain as 10% of total diet dry matter (DM) or 2) GFLAX as 10% of total diet DM. Treatments were top-dressed onto a 25% mixed grass-legume baleage, …
