Rooted Animals

[Fenix025]

I've been reading some posts, but i haven't find this specifically, so here it goes:

When I came back 3 weeks ago i got my last plot back.I shared it with Tacheron, the original and only owner, but he left like 2 weeks or 3 before i did come back, so animals started starving untill dead. When i started feeding them one of the remaining bulls died of starvation, so i got one last to reproduce them and so. Well, the thing is that i've been observing those animals and I've seen some things:

1-Cows:

They regain a bit of quality. The numbers u can see on their profile are the same as they were well feeded all the time, but as u might know they'r milk q and meat q and hide q its very lowered. As their milk regain a bit of quality, or that's what i think ive seen, other qualities dont. Then they stop regaining quality in milk.
Ive placed for nearly one week and a half the "damaged bull" with 2 females with highq (thanks Coles), and they havent done nothing but eating food. No new cows or bulls.

2- Pigs and sheep

Those ones have regained quality in meat, hide and wool, but also they stop this growing a while after the "regain". Ive succesfully reproduced them, but with other damaged animals. Tomorrow ill update this with the experience of sacrificing one. Let's see if they have the stats shown on their profile or some "damaged" ones. In that case, did the devs programed it like that?
