Two experiments were conducted in consecutive years to determine the effects of prepartum nutrient level and postpartum ruminally undegraded protein intake on nutrient status, milk production, subsequent calf production, and reproductive performance of 126 crossbred, primiparous beef heifers. Prepartum treatments were low nutrient intake (LN) (approximately 2.5 kg of TDN, .5 kg of CP animal-1.d...

Previous research has shown that eastern gamagrass (EGG; Tripsacum dactyloides L.) will survive winter climatic conditions common throughout central Wisconsin, and will produce yields of dry matter (DM) ranging approximately from 7,000 to 10,000 kg/ha annually when managed with a 1-cut harvest system. The objective of this research was to determine whether the fibrous nature of this perennial w...

To obtain a comprehensive picture of the spatial distribution of water-soluble organic nitrogen (WSON) in marine aerosols, samples were collected during research cruises in the tropical and southern Atlantic Ocean and also in the southern Indian Ocean (Amsterdam Island) for a 1year period (2005). Samples were analyzed for both organic and inorganic forms of nitrogen, and the factors controlling...

BACKGROUND After an acute attack of pancreatitis, walled-off pancreatic fluid collections (PFC) occur in approximately 10 % of cases. Drainage of the cavity is recommended when specific indications are met. Endoscopic drainage has been adopted as the main intervention for symptomatic walled-off PFC. Altered gastric anatomy in these patients poses an interesting challenge. We present the first c...

An Excel (v 7.0) spreadsheet was created to simplify balancing winter diets (energy and protein), estimating feed needs and evaluating the impact of winter feeding programs on annual cow cost and calf break-even price by using inputs readily found on the farm (e.g., forage test results, accounting and production records). The spreadsheet operates on the substitution method and requires the foll...
