ABSTRACT
La incidencia de problemas alimenticios, nutricionales y metabólicos es cada vez mayor en hatos lecheros, así como la aparición de problemas sanitarios, productivos y reproductivos asociados a los mismos. La detección oportuna y correcta de éstos permite reducir su incidencia y, por tanto, las pérdidas económicas de los hatos. El monitoreo nutricional periódico hace posible establecer el estado nutricional de una población animal, e identificar las posibles causas de desbalances nutricionales y errores en la alimentación, así como orientar en la toma de decisiones acerca de los correctivos que se deben establecer cuando se detectan problemas. El análisis de las posibles relaciones existentes entre la información aportada por cada uno de los aspectos evaluados en el monitoreo nutricional permite una evaluación más adecuada que su análisis independiente y aislado.
Incidence of health and production problems related to feeding, nutrition and/or metabolism have being growing in dairy herds. early diagnosis allows their reduction and consequently reduces economic losses. monitoring nutritional status periodically allows to identify possible causes of nutritional unbalances and/or mistakes in feeding practices and establish corrective measurements.

OBJECTIVE: In this descriptive study we considered age, sex, and admission's month of children under 15 years-old admitted to the emergency room for acute asthma between January 94 to july 95. MATERIAL AND METHOD: There were 594 boys and 421 girls. Male to female mean ratio was 1.4:1. We found a greater and significative admission's number in boys than in girls (x2: p < 0.001). Odds ratio was greater in boys. 1.18 (CI 95%: 1.04-1.35) than in girls, 0.85 (CI 95%: 0.750.96). RESULTS: The acute asthma admissions monthly trend was in third place (median) and second place (mode) when compared with other children's admission diagnoses. Total monthly admissions amount did not show a significative differences when compared the first seven months of 1994 and 1995 (Mann-Whitney's U: p > 0.05). CONCLUSIONS: The acute asthma admissions are currently predominant in boys over girls, and that bronchial asthma is one of the more frequent emergency admission's causes in children.
