Evaluating Corn Silage Quality For Dairy Cattle
Introduction This fact sheet has been developed to support the implementation of the Natural Resources Conservation Service Feed Management 592 Practice Standard. The Feed Management 592 Practice Standard was adopted by NRCS in 2003 as another tool to assist with addressing resource concerns on livestock and poultry operations. Feed management can assist with reducing the import of nutrients to...
متن کاملPlasma and milk urea nitrogen in relation to pregnancy rate in lactating dairy cattle.
The objectives of this study were to relate concentrations of plasma (PUN) and milk (MUN) urea nitrogen to pregnancy rate in dairy cows and compare various methods of analysis and preparation of milk for measuring MUN. In two experiments, blood or milk samples were collected on the day of AI from Holstein cows (n = 160 and n = 155, respectively). Three methods of MUN analysis were compared. Two...
متن کاملAnalyses of rumen fluid from "sudden death", lactic acidotic and healthy cattle fed high concentrate ration.
The sudden death syndrome (SDS) is a relatively new problem in the feedlot industry. With SDS, apparently healthy cattle in late finishing die suddenly with no sign of sickness or lesions indicative of other diseases. Rumen fluid pH, histamine, total lactate, L(+) lactate and volatile fatty acids (VFA) were compared among 19 SDS cattle, two animals with lactic acidosis produced through grain en...
