Just deciding what I'm going to do with groups next year as out of season my hobs and jills are in mixed groups ... and wondered if anyone here has used a delvosterone injection at the start of the breeding season pre-empting the jills' seasons. I did this at the start of the year with Bracken, as she lives with one of my entire hobs, Basil, as one of a pair and I don't want to neuter her or split her from Basil. The injection has kept her out of season for the entire year.
I have some groups of young jills and hobs, and it would be handy if they could all stay together next year. I am not sure if I want to pre-empt the jills' first seasons with delvo as it would be messing with their hormones more than using delvo when in season. But wondered what other people's thoughts on this would be?
In dogs and cats, it has no proven negative effect on fertility or future seasons ...
The other option is to split the hobs from the jills until all of the jills have come into season and been jabbed and then put them all straight back into their groups. My only reservation with doing this is that I find hobs in their first season are actually okay with their jills IF they are not split from them. If they do get split and reunited, they can go a bit hobnoxious and the excitement of seeing their female friends again sends them into man-cave mentality where it may not happen otherwise.
Other option is to implant all of the hobs I'm not using, and physically remove the implant the autumn before I plan to use them .... but I don't like this as it will mean an unnecessary surgical procedure to remove the implant .... I know of quite a few breeders doing this, but it doesn't sit well with me to be honest. Otherwise it would be implanting them and hoping at some point in the next few years it does wear off and the hobs do come back into season. Some of these boys are 4 generations back my own line so I don't really want to lose their possible contribution to the future entirely ....
Edited to add, from the Delvosteron datasheet:
There is a note about not using for the first season in bitches .... but not the same note for queens or jills ....

Jills
Oestrus control: The product can be used to suppress or postpone heat in jills during the breeding season. Following injection in jills showing prolonged oestrus (suppression) the signs will usually abate within 10-11 days. Injections given just before the onset of the breeding season (postponement) or during the breeding season (suppression or postponement) will usually maintain the jill in anoestrus for the remainder of the breeding season.
Further information:
The product may be safely used in breeding bitches, queens or jills; fecundity at the oestrus following the cessation of medication is not adversely affected.
