Abstract

Introduction: Compared to bovine formula (BF), breast milk (BM) has unique properties. In the newborn intestine, there is a homeostatic balance between the counterparts of the immune system, which allows a physiological inflammation, modulated by the gut microbiota. Many studies have attempted to...

AbstractFull Text

Research in volcanic-ash soils has shown that they largely capture the dairy slurry following application to land; however, their hydrological properties would favor nutrient leaching. Our objective was to evaluate the contribution of biogeochemical and hydrological controls on the pollution of...

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...
