2.29.3

kṣīraghṛtabhṛtā hi vatsān upahanyuḥ / iti vetanopagrāhikam //

(1) When a cowherd, a buffalo-herdsman, a milker, a churner, and a hunter (lubdhaka) fed by wages graze milch cows (dhenu) in hundreds (satam satam)--for if they graze the herds for the profit of milk and ghi, they will starve the calves to death,--that system of rearing the cattle is termed ‘herds maintained for wages.’
