The making of milk by a woman's or a female animal's body — the process, and also the period of time it goes on for. It is the noun that goes with the verb lactate, and like it, it belongs to medicine, nursing, and farming rather than to daily chat.

The making of milk by a woman's or a female animal's body女性或母動物身體製造乳汁 — the process就是這個過程, and also the period of time it goes on for也是這段過程持續的時間。It is the noun that goes with the verb lactate它是動詞lactate（泌乳）對應的名詞, and like it而且跟lactate一樣, it belongs to medicine, nursing, and farming rather than to daily chat屬於醫療、護理和畜牧的用語，不是日常聊天的字。

You will see it in fixed phrases: a lactation consultant (a specialist who helps new mothers with feeding problems — a real job title in Taiwanese hospitals too), lactation room (a private room at work for expressing milk), and in dairy farming, a cow's 'lactation period', the months after calving when she gives milk.

You will see it in fixed phrases你會在固定的詞組裡看到它: a lactation consultanta lactation consultant（泌乳顧問） (a specialist who helps new mothers with feeding problems — a real job title in Taiwanese hospitals too)（幫新手媽媽解決哺餵問題的專業人員——在台灣醫院也是真的職稱）, lactation roomlactation room（哺集乳室） (a private room at work for expressing milk)（公司裡讓人擠奶的隱密房間）, and in dairy farming在酪農業裡, a cow's 'lactation period'一頭乳牛的「lactation period」, the months after calving when she gives milk是牠生完小牛後開始產奶的那幾個月。

Because it names the process rather than the act of feeding, it can cover pumping, storing, and supply problems, not just a baby at the breast.

Because it names the process rather than the act of feeding因為它指的是這整個過程，而不是餵奶這個動作本身, it can cover pumping, storing, and supply problems它可以涵蓋擠奶、儲存，還有奶量的問題, not just a baby at the breast不只是嬰兒在吸奶而已。
