Does eating camel meat and fat invalidate ablution?

Eating camel meat nullifies ablution (Wudu') according to Imam Ahmad. The Hanbalis differed regarding the nullification of ablution by eating camel fat, other parts of it, its broth, and its milk. Al-Mardawi mentioned in "Al-Insaf" that the dispute extends to the other parts besides the meat. In "Al-Furu'," there are two narrations concerning the ruling on the remaining parts, broth, and milk. Also, in "Al-Ri'aya Al-Kubra," there are two opinions regarding its hump, fat, broth, stomach, and intestines, and it was also said concerning its skin and bones. Al-Mustaw'ib mentioned two opinions regarding its fat.
