Breeding Statistics / Part III

[muddoc]

I know that the last two times we posted this, everyone found it very interesting, and I couldn't help but put it up again. I have seen a very large increase this year in questions from new breeders that this data can answer. Contraty to this quote,"I am going to try and keep a running tally this year, so that the data will already be compiled once the last baby hatches", that I made last year, I did not keep all of the data, and had to go dig it all up. Once again, I know that this data comes late, but I still thought people breeding now would find it interesting. I posted links to the previous year's postings, however, all of the data from all three years is included in this thread. I did grab some data this year that I missed last year, so there are a few holes in the data.

Below is the link to the 06/07 year's thread, followed by the 07/08 year's thread:

Without further ado, here are the numbers (the first number is the 06/07 season, the second number is the 07/08 season and the third number is 08/09):

Total females in our breeding program: 40 / 71 / 94

Total females that copulated at least once: 35 / 68 / 84

Total females to lay eggs: 21 / 45 / 58

Breeding success rate: 53% / 63% / 62%

Total Slugs: 4 / 20 / 30

Total infertile eggs: 4 / 4 / 14

Total eggs that went bad during incubation: 12 / 18 / 13
Average Clutch Size: __ / __ / 5.7 eggs (I didn't figure this out the first 2 seasons)

Total good eggs that went full term: 118 / 224 / 306

Total hatchlings: 118 / 221 (3 died in egg after cutting) / 282 (24 died in egg)

Total hatchlings that died: 0 / 2 / 2 (1 died within 1 week, and one died after three months of thriving. My guess is that it had some internal problems, as it regurged it's last three meals before dying).

Final Sex Ratio: 55.64 / 130.91 / 133.149

As I stated in last year's thread, I didn't collect this data in 07/08, but I got some of it this past year.

Lightest Hatchling: 23.0 grams / __ / 24.0 grams

Heaviest Hatchling: 87.6 gram / __ / 92.6

There are too many hatchlings now to keep up with this. Sometimes data collection can impede the important stuff, but the data below was on a pretty good sample size, and I thought it may help someone, so I left it in here.

Total Hatchling Weight: 6911.3 grams (we hatched 15.36 pounds of snakes)

Average Hatchling Weight: 60.1 grams


I hope someone could find this interesting, or at least, it can help someone plan for how there seasons will work for them in the future.
