Abstract
This pragmatic article founds grounds to establish a farm policy to include multiple sources of starch in commercial ruminant diets to improve rumen and ruminant health. Rumen environment has a dramatically fluctuating nature that requires versatile species of microbes to inhabit. As such, multiple sources of differently fermentable starch (varying degradation extent and rate) are required to maintain ruminal microbial versatility and integrity. For its considerable dietary inclusion rate, starch from multiple grain and forage sources better meets energy requirements of a variety of microbial groups and helps minimize risks from metabolic complexities such as subacute rumen acidosis and immune deficiency.
Highlights
Innovations and Discussion reduce microbial growth, efficiency and yield. This is because given microbial groups' requirements for particular fermentation behaviour may not be optimally met when only specific types of starch are fed
Feeds with fitting extents and rates of degradation must be provided towards securing such microbial growth and efficiency. This match-feeding of rumen microbes, helps minimize energy loss and risks from metabolic problems such as SARA, bloat, endotoxemia, immune deficiency, and hepatic malfunction [6,7]
Starch properties A variety of cereal grains are planted worldwide and fed to ruminants mainly based on their availability and costs
Summary
Innovations and Discussion reduce microbial growth, efficiency and yield. This is because given microbial groups' requirements for particular fermentation behaviour may not be optimally met when only specific types of starch are fed. Rumen environment Rumen possesses highly varying biophysical and biochemical conditions that require fitting microbial versatility and feeding management [1,2,3].
