Abstract

Administration of monensin to dairy cows during the transition period may improve cow health, although this is debated. An evaluation of the effects of an intraruminal controlled-released bolus of monensin on health and milk production in transition Holstein cows was done in a Chilean dairy farm....

Abstract

The objective was to analyze the effect of feeding dry molassed beet pulp (DMBP) on milk yield and milk composition in Holstein cows located in central Chile. Cows with similar days in milk, parity number, and management were randomly allocated in a control (n=71) and a treatment (n=74) group. The...

Abstract

Bulls in dairy production are usually slaughtered at an early age to avoid production problems and unnecessary costs. However, the animals could be a source of additional income and better quality meat. The objective of this work was to determine the characteristic and quantity of fatty acids of...

Abstract

Background: Ketogenesis is a secondary metabolic pathway to provide energy to dairy cows during early lactation; however when the production of ketone bodies (acetoacetate, acetone, β-hydroxybutyrate) is above certain levels a subclinical disorder may appear. The aim of the present study was to...

Abstract

The objectives of this study were to describe the incidence of postpartum disease and to evaluate the association with serum cholesterol concentrations during the first 3 weeks after calving in grazing dairy cows. The association between non-esterified fatty acids (NEFA), β-hydroxybutyrate (BHBA),...

Abstract

The objective of this work was to assess the potential of near infrared spectroscopy to predict the immunoglobulin G (IgG) content in bovine colostrum. Liquid colostrum samples (n=157) were collected from Holstein cows from 2 dairy farms in southern Chile. Samples were obtained within 1 h of...

Abstract

Lameness is one of the greatest infringements of welfare in dairy cows. The objective of this study was to investigate associations between milk yield and foot lesions causing lameness in Chilean dairy cattle with the hypothesis that if we can demonstrate that lameness reduces yield, and so income, ...
