Última DAIRY HEIFER MORBIDITY, MORTALITY, AND HEALTH MANAGEMENT FOCUSING ON PREWEANED HEIFERS AgEcon Ott, Stephen L.. The National Dairy Heifer Evaluation Project ( NDHEP ) was conducted by the National Animal Health Monitoring System (NAHMS ) from April 1991 through July 1992. A total of 921 producers monitored calves on a daily basis from the first through the eighth week of life; results were extrapolated to the U.S. dairy population. Mortality of heifer calves was examined according to region ( west, midwest, northeast, southeast ). Mortality was highest in the western region ( 9.1 percent ) and lowest in the midwestern region ( 5.6 percent ). Calf deaths were highest in the two quarters October-December and January-March ( 8.4 percent each quarter ) and lowest in the quarter April-June ( 5.2 percent ). The overall average of stillborn calves was 1.6 percent. Calving...

Ano: 1993 URL: http://purl.umn.edu/32756 DAIRY HERD MANAGEMENT PRACTICES FOCUSING ON PREWEANED HEIFERS AgEcon Ott, Stephen L.. The National Dairy Heifer Evaluation Project ( NDHEP ) was conducted by the National Animal Health Monitoring System (NAHMS ) from April 1991 through July 1992 with the assistance of 1,811 producers from 28 states. Producers included in the study each had herds of 30 or more milk cows, representing 78 percent of the milk cows in the U.S. The average total of cattle and calves on each operation was 169.4. The main breed on 94.9% of operations was Holstein. Slightly over 46 percent of operations stated reproductive problems as the cause of low milk production of cows culled from the herd. Newborn calves were separated from their mothers before nursing on 28.0 percent of operations and less than 12 hours after birth on 39.6 percent of operations. On 64.0...

The fermentative, microbiological and nutritional dynamics of bovine colostrum fermented under anaerobic conditions at different temperatures is provided. Colostrum was homogenized and stored in PET bottles in anaerobic conditions and incubated at controlled temperature (32.5 ± 1°C or 22.5 ± 1°C) or at room temperature (17.4 - 21.5ºC) and opened after 0, 1, 7, 14, 21, 28 and 35 days to determine fermentative and nutritional parameters and bacteria, yeast and mold counts. Further, pH rates showed significant variations during the fermentation period (p < 0.0001), with colostrum stored at 32.5°C, exhibiting the lowest rates and significant reduction during the first days. Titratable acidity and lactic acid concentration showed increasing rates and LAB...
