Sorry but if you say you are going to try to get a female up to weight for upcoming season, and she is still 800 grams I highly doubt you know what you are doing.

I have 2010 females 1300 grams and up and I'm still giving them another year to grow up. Don't push your yearlings when you are only thinking about breeding.

The health of your animals is what should concern you most - breeding comes second.

Greets,
