<p>This feeding trial was designed to investigate two separate questions. The first question is, “What are the effects of substituting two non-fiber carbohydrate (NFC) sources at two rumen-degradable protein (RDP) levels in the diet on apparent total-tract nutrient digestibility, manure production and nitrogen (N) excretion in dairy cows?”. This is relevant because most of the N ingested by dairy cows is excreted, resulting in negative effects on environmental quality. The second question is, “Is phenotypic residual feed intake (pRFI) correlated with feed efficiency, N use efficiency, and metabolic energy losses (via urinary N and enteric CH4) in dairy cows?”. The pRFI is the difference between what an animal is expected to eat, given its level of productivity, and what it actually eats. The goal was to determine whether production of CH4, urinary N or fecal N is a driver of pRFI.</p> <p>This experiment was conducted at the Dairy Cattle Center of University of Wisconsin-Madison. The use and care of animals was approved by the University of Wisconsin-Madison Research Animal and Resource Committee.</p>

Intended use

This dataset provides basic information on the response of milk production, animal nitrogen balance, and methane emission to dietary changes, especially changing protein and starch levels. The information can be used to modify dairy cow diets to achieve environmental quality goals. The data can also be used to parameterize statistical or simulation models of dairy cow metabolism or production performance, to investigate further questions about optimal feeding and treatment of the animals.

Use limitations

The data are specific to the breed, age, parity and housing conditions of the animals in the experiment, and should be extrapolated to other contexts with care.
