Скачать или смотреть Nitrooxypropanol (3-NOP): Effects on Enteric Methane, Feed Intake, and Milk Yield in Dairy Cows

Enteric methane emissions from dairy cows are a major challenge for sustainable livestock production. In this video, we examine the first methane mitigation strategy in our series: 3-Nitrooxypropanol (3-NOP).

Based on results from multiple controlled studies in lactating Holstein dairy cows, we explain how supplementing diets with 3-NOP at 40–80 mg per kg of dry matter intake can reduce enteric methane emissions by approximately 25–40%, while maintaining dry matter intake and milk yield.

This video focuses on:

How effective 3-NOP is at reducing enteric methane

Whether methane reduction is stable over time

The effects of 3-NOP on feed intake

The impact of 3-NOP on milk production

Changes in rumen fermentation efficiency

Importantly, the studies discussed show that methane reduction with 3-NOP is not associated with a significant decrease in milk yield, making it one of the most promising nutritional tools currently available for methane mitigation in dairy systems.

In upcoming videos, we will analyze and compare other methane mitigation strategies, including dietary fats, nitrates, and seaweeds, using data-driven and science-based comparisons.
