Unfortunately there really havn't been very many people who have bred amarali & most of (me anyway) just don't have the time to visit this forum very often.
Anyway, here's some temp info from last season. Keep in mind that I heat my breeding room & have day/night setbacks on it. Each cage also has flexwatt hot spots which are turned on in the daytime mode only. My normal sumertime room temps are 85 deg. daytime/78 deg. night. On 11/30/03 I dropped the daytime high from 85 to 82 & nightime from 78 to 73. I also shortened the day from 15 hrs to 11 hrs. On 12/6/03 I dropped the daytime high from 82 to 80 & nightime from 73 to 69. On 12/15/03 I raised the room temp from 80 to 81 & dropped the nightime from 69 down to 66. If I remember correctly this is around when I introduced the males. On 12/30/03 I raised the room temp from 81 to 82 & raised the nightime from 66 to 73 & made the daytime 12 hours. Finally on 2/3/04 I put all temps & timers back to normal. Ovulations on the amarali were noticed on 3/02/04 (Bolivian), 4/07/04(S. Brazilian), & 4/13/04(S. Brazilian). There may be one more gravid that I missed also.
Hope this helps & remember that everyone does everything a little differently so just experiment & see what works for you. The most important thing is to have a good male & they seem to be scarce as hens teeth. I have produced clutches in previous years without any vigirous cooling. Last season was my first with serious cooling so we'll see how it goes. My first litter (N. Brazilians) was due a couple days ago counting 115 days P.O.S. My Guyana female is due today & Bolivian is due the 14th. Then I get a couple week break fortunately. Hopefully things will turn out nice. Nothing better then having them go past their due dates in my opinion.
