· VFA analysis & ammonia
Volatile fatty acids analysis gives producers an idea of what the fermentation has done in the silo, in terms of proper fermentation levels, and is useful in predicting the performance in terms of rumen microbial performance and milk protein production. Excess ammonia from forages can be wasted if not properly balanced across all the diets in a herd.
· Amino acids
Balancing diets for amino acids takes precedence over balancing metabolizable protein or crude protein. Accurate amino acid profiles of proteins and byproducts provides knowledge to properly balance low protein (14 to 15 percent) diets with milk urea nitrogen (MUN) tank levels below 10. This improves protein purchases and reduces nitrogen losses.
· Fatty acids
Fatty acids provide a more accurate measure of true digestible energy coming from the fat of forages and ingredients. Fatty acid profile improves the ability to balance poly-unsaturated fatty acid (PUFA) load which has a bearing on reproductive performance and milk fat yield.
“Evaluating feedstuffs prior to feeding will help to optimize your rations for optimal health, milk components, income over feed cost and overall profit potential,” says Roseler.
