TLDR
In this paper, 12 lactating Holstein cows were used in a 12-week experiment to compare a conventional concentrate mixture containing: 4.2% ether extract and 13.5% crude protein with the same mixture modified by the addition of soybean oil in different combinations with protein.About:

Fat in lactation rations: review.
D.L. Palmquist,T.C. Jenkins +1 more
TL;DR: Current research and practice demonstrate that 3 to 5% fat may be added to diets for lactation to increase energy intake of high-producing cows and/or to reduce starch feeding, thereby increasing the ratio of forage to concentrate to prevent depression of milk fat.

Effects of dietary fat on metabolic disorders and reproductive performance of dairy cattle
Ric R. Grummer,D.J. Carroll +1 more
TL;DR: Energy balance data for early lactation cows fed supplemental fat are not plentiful; however, slight but statistically nonsignificant increases have been observed when feeding fat.
Journal ArticleDOI
Effects of feeding lactating dairy cows diets containing whole soybeans and tallow.
TL;DR: The data indicate that relatively large amounts of unprotected fat can be added to the diet of lactating dairy cows without deleterious effects on milk composition, ruminal fermentation, or nutrient digestibilities.

Heat-Treated Soybeans for Lactating Cows
C.D. Mielke,David J. Schingoethe +1 more
TL;DR: In this article, an experiment with 12 cows in switchback design determined the feeding value of a heat-treated soybean product, and the results showed that milk production by cows past peak production was not significantly greater than production with conventional corn-soybean meal diets.

TL;DR: In this article, the authors measured milk yield, mammary blood flow and arteriovenous differences of each plasma lipid fraction, and their specific radioactivities, during the infusion of [U-(14)C]stearate, oleate and palmitate into fed lactating goats.

TL;DR: The proposed method correlates with the method of Abell et al., has a repeatability of 0.7%, a day-to-day variability of 2.8% and a reproducibility between laboratories of 1%.
