RUMINANT ENVIRONMENTAL IMPACT
However, this research will need to be translated into
meaningful data/end-products that can be used at farm level if
it is to be effective. An example in progress is the use of buccal
fluid as a predictor of the rumen microbial community.
Are genetics the key to methane reductions?
From a political and public relations standpoint, the
need for methane reduction is more likely the most crucial in the immediate future, and there are a myriad of
strategies that can help to reduce methane but, ultimately,
genetic selection might be the greatest, most feasible and
long-term method, from a commercial standpoint.
We also know microbial diversity is key to efficiency
and health; therefore, people have begun to ask, "What
constitutes a healthy, effective microbiota, and what sort
of aberrant deviations can occur?"
Research has shown that it may also be unwise to focus
primarily on reducing methane - a rumen that exhibits
reduced methane production isn't necessarily more efficient. Having said that, ruminant agriculture still needs to
be seen to be addressing the environmental impact of ruminant livestock and reducing methane output is viewed,
by many consumers, as the most critical parameter.
To that end, maybe it would be better to look at the
most beneficial rumen ecosystem as far as balancing
production efficiency and emissions. Metagenomic whole
gene and 16S rRNA sequencing have been effectively used
to investigate microbial diversity in humans, as well as
animals (including ruminant microflora), and the Hungate
1000 project is attempting to address microfloral diversity
and its role in rumen function with the aim of developing
methane mitigation strategies without losing productivity.
The project is looking to generate 1,000 reference microbial genome sequences of bacteria, archaea, fungi and

Formulating DDGS into Monogastric Diets to Maximize Profits
Feed costs represent the greatest expense associated with swine or poultry
production. Utilizing less expensive ingredients, such as DDGS, reduces costs
and maintains animal performance. However, the process for ethanol production
continues to evolve, changing nutritional characteristics of DDGS. As a result,
strategies for DDGS inclusion in monogastric diet formulation also need to adapt.
This webinar will discuss practical approaches for including DDGS in both swine
and poultry diet formulations as well as provide insights into how DDGS can
provide an economical alternative to other higher priced ingredients.
