Última MORBIDITY/MORTALITY AND HEALTH MANAGEMENT OF SWINE IN THE UNITED STATES AgEcon Bush, Eric J.. A national survey on swine health was conducted by the National Animal Health Monitoring System ( NAHMS ) from December 1989 through January 1991. The survey sample was designed in collaboration with the National Agricultural Statistics Service (NASS ) in order to provide inferences about the nation's hog population, 95 percent of which was represented. The program consisted of two parts: the first was a general farm management and policy questionnaire that was completed by 1,661 producers. The second part of the program was a monitoring phase that took place over a three-month period for each of 712 participating producers. Per litter estimates for the national population showed an average of 9.9 piglets born alive and 8.4 weaned. Estimates attributed 57...

Ano: 1992 URL: http://purl.umn.edu/32761 DAIRY '96, PART I: REFERENCE OF 1996 DAIRY MANAGEMENT PRACTICES AgEcon Ott, Stephen L.. The NAHMS Dairy '96 Study was designed to provide both participants and the industry with information on the nation's dairy animal population for education and research. The USDA's National Agricultural Statistics Service (NASS) collaborated with NAHMS to select a statistically valid sample yielding 2,542 producers. Included in the study were 20 states that represented 83.1 percent of the U.S. milk cows as of January 1, 1996. NASS interviewers collected data for Part I via a questionnaire administered on-farm from January 1 through 26, 1996.

Ano: 1996 URL: http://purl.umn.edu/32758 EQUINE '98, PART I: BASELINE REFERENCE OF 1998 EQUINE HEALTH AND MANAGEMENT AgEcon Garber, Lindsey. The NAHMS Equine '98 Study was designed to provide both participants and the industry with information on the nation's equine population for education and research. The USDA's National Agricultural Statistics Service (NASS) collaborated with NAHMS to select a statistically valid sample such that inferences can be made for all places with equids and for all equids in the participating states. Included in the study were 28 states that accounted for 78.2 percent of the U.S. horses and ponies and 78.0 percent of farms with horses and ponies. NASS interviewers collected data from 2,904 participants via questionnaire from March 16 through April 10, 1998 for Part I. Inventory data from the 133 participating race tracks were included in this report....

Ano: 1998 URL: http://purl.umn.edu/32746 Daily birth numbers in Passo Fundo, South Brazil, 1997-1999: trends and periodicities BJMBR Mikulecky,M.; Lisboa,H.R.K.. Between October 6, 1997 and April 30, 1999, 5011 births (mean: 8.76 per day) were registered in the city of Passo Fundo, South Brazil. The sequence of 572 daily birth numbers was not random (iteration test). Neyman distribution (m = ¥) showed the best fit. Clusters of days with higher birth numbers alternated with days with low numbers of births. Periodogram analysis revealed a significant periodicity of 6.98 days. The cosinor regression, testing 10 a priori supposed period lengths, found significant seasonality peaking in August-September and significantly highest birth numbers on Thursdays. Among the lunar and solar rotation cycles, the tropic lunar cycle and its 4th harmonic were most pronounced, in agreement with results concerning natality in Germany...
