There is nothing wrong with giving from the udhiyah meat to non-Muslims especially if they are relatives or neighbours or poor.

The Shar`i evidence indicates that a sheep that has reached the age of six months may count as a sacrifice, as may a goat that has reached the age of one year, a cow that has reached the age of two years, and a camel that has reached the age of five years. Sacrificing an animal that is younger than that is not permitted, but if an animal that is older than that is sacrificed, it is permitted and is better.

The one who offers the udhiyah should be independent of means, in that the price of the udhiyah is surplus to his needs and the needs of those on whom he spends. The udhiyah is prescribed for the members of the household. If a woman is living on her own or with her children, then she should offer the udhiyah.

The Sunnah for one who wants to slaughter the udhiyah is to say: Bismillah, wa Allahu akbar, Allahumma hadha minka wa laka, hadha ‘anni (or if it is being offered on behalf of someone else, hadha ‘an [fulan]), Allahumma taqabbal min [fulan] wa ali [fulan].
