Cow

Nanda Maharaja had 900,000 cows. Visvanatha Cakravarti gives this description of the cows of Vrindavana. Krishna knew every cow by name. If any cow was missing Krishna would immediately chase after the missing cow and call her by name. The cows were divided into herds by color, either

1. black, 
2. white, 
3. red, or 
4. yellow. 

In each color there were

1. 25 further divisions 
2. making a total of 100 herds. 
3. There were also eight herds of cows that were spotted or speckled or had heads shaped like a mridanga or that had tilak marks on their foreheads. 

There was a total of 108 different herds of cows. Each of the 108 herds had a herd leader.To count these 108 groups of cows, distinguished by colour and form, Krishna uses a mala of 108 jewel-beads.

For cows, Krishna sits atop a tree and plays flute to keep a check on the number of 9 hundred thousand cows herding with Him. Before returning home, He calls each and every one of the cow by her name – through the sound of His flute. He calls all of them one by one – Chandrika, Dhavali, Ivali..When He playes flute for Chandrika cow, only Chandrika is able to hear her name through the sound of Krishna’s flute. She gets delighted to hear her name being called by Krishna and comes running towards Him. Then He calls Dhavli, Ivali and every other cow in the same way. Thus no cow is left behind.

Thus when Krishna calls out,

Color

1. 'Hey Dhavali' (the name of a white cow) a whole group of white cows comes forward, and when Krishna calls 'Hamsi, Candani, Ganga, Mukta' and so on, the twenty-four other groups of white cows come. 
2. The reddish cows are called 'Aruni, Kunkuma, Sarasvati, etc., 
3. the blackish ones 'Shyamala, Dhumala, Yamuna, etc., and 
4. the yellowish ones are Pita, Pingala, Haritaki, etc. (Srimad Bhagavatam 10.35.19 purport)

Mark

1. Those in the group with tilaka marks on their foreheads are called Citrita, Citra-tilaka, Dirgha–tilaka and Tiryak-tilaka. (Ibid.) 
2. There are groups known as Mrdanga-mukhi [mridanga-head], Simha-mukhi [lion-head] and so on.
