Ntim Khoom Thiab Khaws Cia
1. Ntim: Cov ntawv yas sib xyaw hnab ntim thiab hlua nrog cov hnab yas, 25kg / hnab.
2. Kev Khaws Cia: Cov khoom yuav tsum khaws cia rau hauv qhov chaw qhuav, txias, muaj cua nkag, thiab tiv taus nag, deb ntawm cov chaw kub. Qhov kub khaws cia yog qis dua 25 ℃ thiab qhov av noo tsawg dua 60%. Lub sijhawm khaws cia yog 12 lub hlis, thiab cov khoom tuaj yeem txuas ntxiv siv tom qab rov kuaj dua thiab tsim nyog thaum tas sijhawm.
