Srimad Bhagavatam Canto 10, Chapter 27, Text 18

SB 10.27.18

athaha surabhih krsnam
 abhivandya manasvini
sva-santanair upamantrya
 gopa-rupinam isvaram
 
Translation: 
 
Mother Surabhi, along with her progeny, the cows, then offered her obeisances to Lord Krsna. Respectfully requesting His attention, the gentle lady addressed the Supreme Personality of Godhead, who was present before her as a cowherd boy.
 
Purport: 
 
The statement here that the heavenly cow Surabhi approached Lord Krsna along with her progeny (sva-santanaih) is a reference to the transcendental cows who play with Lord Krsna in Vrndavana. Although Lord Krsna’s cows are transcendental, the heavenly cow Surabhi affectionately saw them, as indeed Lord Krsna Himself did, as related to her. Since Lord Krsna was appearing in the form of a cowherd boy, the whole situation was quite congenial, and Surabhi took the opportunity to offer the following prayers.
