Tridge summary

A recent study aims to address the mystery surrounding the low milk production and fat content in dairy from Southeast Asian countries, particularly Thailand and Vietnam, by focusing on the fermentable organic matter (FOM) content of tropical forages. The study was conducted due to the lack of data on FOM in these regions and seeks to provide solutions to improve milk production and quality. The research utilized innovative testing methods, including an in vitro automated gas production test and the nylon bag technique, to evaluate the FOM content of common tropical grasses in Southeast Asia. Additionally, the study suggested strategies for enhancing harvest times and formulating dairy cow diets to optimize milk production and fat content, offering promising insights for improving dairy farming efficiency and productivity in the target countries.

Original content

SummaryIt is often claimed that the fermentable organic matter (FOM) content of tropical forages is low and that this is the reason for low milk production and low milk fat content in some Southeast Asian countries. In practice, the FOM content of forages, including fresh grasses, is largely unknown because it is not routinely measured in Southeast Asian countries. The study described in the thesis investigated the FOM content of tropical grasses common in Southeast Asia to determine whether milk fat content can be increased. The study used an in vitro automated gas production test and the well-established nylon bag technique to assess the breakdown of grasses in the rumen of dairy ...
