Epidemiology of cattle diseases in the northeast of La Pampa, Argentina

Abstract

A cross-sectional survey was carried out on 350 farms in the north east of La Pampa Province, Argentina. The goal was to record the prevalence of cattle diseases reported by farmers. Farms were stratified into three categories on the basis of adult herd size (300 to 500 cattle, 500 to 900 cattle and greater than 900 cattle) and a random sample selected from each strata. According to the productive system, farms were classified as fattening (F), cow-calf (C) and cow-calf-fattening (CF). Presented data are part of a comprehensive survey on cattle farms performed by INTA and Ministry of Production staff. The information described on this assay corresponds to principal signs and health problems recorded in different farms. Actinosis (n = 115 farms), bovine respiratory diseases (BRD) (n = 77), neonatal calf diarrhea (NCD) (n = 60), copper deficiency (n = 54), and blackleg, gas gangrene and enterotoxaemia (BGE) (n = 39) were the main diseases. NCD and BGE were geographically distributed on the southern half area, while actinosis, copper deficiency and pneumonia were distributed on the central-west area. BRD also showed a second risk area on the northwest. According to production system, BRD was found to be associated to F, while NCD, copper deficiency and BGE were associated to CF. According to strata level, no differences were found for any diseases considered for the present essay.

Factores de riesgo asociados a la aparición de alteraciones ganglionares mandibulares en bovinos

“…Un estudio de prevalencia realizado por el autor en un distrito de la Provincia de Santa Fe, arrojó una prevalencia de 0,66% (n= 10980). También, en la Provincia de La Pampa, se obtuvo una prevalencia de actinobacilosis y actinomicosis del 2,51% 8 . De esta manera, los estudios realizados en diferentes momentos, sobre poblaciones bovinas en lugares distintos, son consistentes con los resultados del presente trabajo, sugiriendo la presencia endémica de la enfermedad, aunque con baja prevalencia.…”

“…Sin embargo, datos de decomisos en frigoríficos a nivel regional y local, sugieren que esta enfermedad supera las presentaciones esporádicas 3,8 . A partir de la descripción en Argentina de la actinobacilosis bovina en 1902 6 se ha generado información sobre el agente causal y el proceso patológico, pero poco se conoce sobre los factores que se asocian a su presentación.…”

Prevalence of different dairy cattle diseases in selected dairy areas and farms of Bangladesh

“…The contribution of livestock in the magnitude of Gross Domestic Product (GDP) is about 16.23 % in Bangladesh (BBS, 2008). Cattle are very important component of the mixed farming system practiced in this country and health of cattle is one of the many factors that conspire against productivity of cattle production systems all over the world (Miranda, 2014). However, most of the animals in Bangladesh are weak and emaciated with non-satisfactory productive performance due to malnutrition and diseases.…”
