Milk samples were collected in the morning (07:00–08:00 h) and afternoon (16:30–17:30 h) for five consecutive days during early and late lactation. Within the day, de novo FA as the total FA basis was higher in the morning than in the afternoon, whereas preformed FA as the total FA basis was lower in the morning than in the afternoon. The weighted averages of milk FA composition according to milk yield collected in the morning and afternoon were significantly different between cows in early and late lactation; however, these were not significantly different among the consecutive five sampling days in each period. It was concluded that milk samples collected in the morning and afternoon for 1 day are suitable for milk FA determination.

By measuring the changes in milk amount after different durations of milk accumulation (0–24 h) using a ductal cannulation technique and oxytocin supplementation, we estimated the milk production rate at a single mammary gland level. In addition, collected milk was available to assess milk quality, including creamatocrit, osmolarity, and concentrations of ions, lactose, and total protein. Moreover, as a proof of principle, the effects of intraductal administration of a hypertonic solution to the abdominal mammary gland were examined.

Early lactation dairy cows may develop endoplasmic reticulum (ER) stress in the liver, potentially leading to liver-related diseases and contributing to ER stress in mammary epithelial cells, resulting in decreased milk production. Natural products that alleviate ER stress have been identified, and if further in vivo studies confirm their efficacy, they have potential as feed additives to prevent disease and reduce milk yield.
