What is the ruling on eating the meat of a kid goat that suckled from a female pig, or offering it as a sacrifice?

The milk of a pig is impure (najis), but if a kid suckles from a pig, the effect of impurity does not appear in its flesh. The majority of scholars are of the view that the flesh of the kid does not change due to impure milk, and that the milk transforms into another nature after being drunk, so it does not take the ruling of a "jallalah" (an animal that feeds on impurities) and its consumption is not disliked.

A "jallalah" is an animal that habitually eats carrion and does not mix its diet, and its flesh becomes foul-smelling, making its consumption forbidden. However, an animal that mixes its diet, consuming both carrion and other things in a way that its effect does not appear in its flesh, then there is no harm in eating it. So, if a kid suckles from a pig or a dog until it grows up, its consumption is not disliked because its flesh does not change as a result.

Impurities that undergo changes and transformations, when they become food and parts of organs, become pure after the transformation.

Based on this, there is no harm in sacrificing this kid. However, according to the view that its flesh is affected by suckling and becomes foul, if its suckling from the pig reaches the extent of a jallalah, then it takes its ruling. A jallalah is not sufficient for sacrifice if it eats nothing but impurities.
