Mishna Berurah in your Mailbox

Today's halachos deal with saying the sections of korbanos during Shachris. The gemora explains that today in leu of being able to offer korbanos, being involved with these sections of Torah are considered as if one has offered the korbanos. Thus, there is discussion regarding whether the details of saying the sections korbanos should be similar to the halachos of sacrificing the korbanos in the Bais Hamikdash:

Korbanos were only offered during the day.

Voluntary korbanos were not offered during the week.

The korban chatas required that one have knowledge that he did something wrong in order to be able to offer the Korban. 

More details of these halachos are discussed further in siman 48. 

It is best to recite the Parshas Hatamid and the korbanos in shul before Shacharis (as printed in the siddur). However, one should not miss davening with the tzibbur in order to recite these sections, as they can be said after davening if need be. - Beur Halacha ד"ה ופרשת

Even those who generally do not recite the sections of Korbanos, should at a minimum, get into the habit of saying Parshas Hatamid. (Bamidbar 28:1-8)
