The aim of this study was to analyze the relationship of the body condition score (BCS) with milk yield, reproductive efficiency and the postpartum metabolic profile in Holstein cows of the Bolivian tropics. Sixteen primiparous and multiparous Holstein cows aged between three and seven years were monitored during the first 150 days of lactation. The pre-partum BCS was better than during the post-partum period (p<0.05). However, there were no significant differences between BCS and daily milk yield, milk production in the first 150 days, body weight, calving to first service interval and calving to conception interval. The components of the metabolic profile (glucose, aspartate aminotransferase, alanine transaminase, total protein, albumin and urea) did not show significant differences due to BCS.

Background: Point prevalence surveys (PPSs) on antibiotic use are useful for understanding different aspects related to prescription patterns in hospitals. Methods: An adaptation of the WHO methodology for a PPS on antibiotic use was applied. Hospital wards were divided into medical (MED), surgical (SUR), ICUs, gynaecology and obstetrics (GO), high-risk (HR) and mixed wards (MIX). A web application (RedCapVC ) through a mobile device was used for data collection. Results: Between December 2018 and August 2019, 5444 patients in 33 hospitals in five countries were included (10 hospitals in Cuba, 7 in Paraguay, 6 in El Salvador, 5 in Mexico and 5 in Peru). Of these patients, 54.6%received at least one antibiotic, with variations between and within hospitals and countries. Antibiotics were more frequently used in ICUs (67.2%), SUR (64.5%) and MED wards (54.2%), with 51.2% of antibiotics pres...
