so how long ...
... are c.batesii gravid anyway? for many species it's figured out with only a couple of days either way for date of birth after ovulation, and for these animals I read 200-250 days which is quite an overlap. maybe I'm just looking in the wrong places :roll: Jurgen.

200 plus days for sure. Mine ovulate in late April to the end of May. They give birth from late Nov. to late Dec.

Can be a lot lower. Basin Pre ovulation swelling 4 April, birth 6 Sept = 155 days. Post Ovulatory Shed + 134.

Steve & Jules, Does the temperature make a difference in the lenght of time to birth? If you think so, what temps did you keep your females at to arrive at the difference in the number of days? Thanx, Craig

Craig. I should think temps play a part in the length of pregnancy. In this case she had the option of 80-95 F 24/7 though i dropped this slightly for the last 3 weeks as she was spending more time at the cooler end.

Jules temps are a good 5 degrees higher than I use.

Jules temps are a good 5 degrees higher than I use. She spent most of the time at 95 because she chose too! My cages are large and she had the options to stay at 80F 24/7 if she wanted. Whats the problem?. There is no " It must me done this way" formula. I think it might be better to give them an option of a large temperature gradient rather than to assume we know " exactly" what they want because that is not the case. As Peter O'toole said to his young admirer in Lawrence of Arabia "Nothing is written !" In this case she dropped only 3 days shy of the generally accepted average POS + 137. The survivors were born 50g + and are thriving. The job was done!

Jules , I have NO problem . I was merely stating the facts. I use a lower temp than you , period. Sounds like you have great success . How many were slugs or still born. I have read accounts that suggest high temps with no night drop lead to still higher than average slugs and still born babies. I have one female that gives me 70 gram babies. She is huge!

Jules temps are a good 5 degrees higher than I use. My apologies Kyle! I thought you were addressing me directly with the above quote. Only six live 1 slug. 3 apparantly healthy and well formed died within 48 hrs. Wierd!. For a 5ft female with a just a short time with a male i was happy with that.

Jules , no worries. In my opinion , basins would have a hard time reaching 95 degrees in the tree tops. Please don't take this as a critique, only a suggestion. You may be interested in trying lower temps next time, as I have heard others tell stories of high slug count, full term deaths , babies dying when using high temps (90+) and no night drop. As you said before , no one has all the answers , but lower temps and a night drop will NOT have a negative impact on your results, quite the opposite in my opinion. I have only produced 5 litters over the last 4 years so I am hardly the most experienced with basins. Out of those 5 litters I have only had 2 or 3 slugs and 1 born dead. Lower temps may take a while longer but certainly won't hurt your results. You seem to know what you are doing, just thought I would give you something to think about. Good luck , and continued success! Kyle
