Pregnant RTB?

Pregnant RTB?

Postby JamesR » Wed May 18, 2011 2:55 pm

I have had a male and female RTB for the past 2.5 years. The male is about 1.7 metres and the female about 1.9 metres long. My female weighs between 5.5 & 6kgs. They have been kept in the same cage since I got them at 3 weeks olds. They have mated on and off over the past 6 months but I never changed the temperature or light settings in the cage as I was not intent on breeding them this year. Neither boa has ever refused a meal until 6 weeks ago. The male has continued feeding as eagerly as ever; however, the female has shown no interest in feeding over the past 6 weeks. Having said that, she has definitely gained weight and considerable girth in her rear half. I trust that she is gravid and having never bred boas before I was hoping to get some advice at what stage she might be at and what to expect from here on, especially with regards timing to ensure I have the necessary food supply etc. should she give birth. I am attaching 2 photos taken today to indicate the swelling. I hope this will be sufficient for an assessment. How many offspring should I expect for a boa of this age and size?

I have been trying for the last hour to figure out how to insert an image including using the search function! Alas, no joy. I eventually managed to get 2 images into the gallery, but then what? If the images do not appear, please could somebody explain how to load an image in a post. Thank you.

To try and predict how many babies a boa will have is not that easy. She could have 10 huge babies, or 20 or 30 smaller babies. Size and weight have nothing to do with it. I've had a female in prime condition who only had 15 babies, and then someone else's boa who was skinny have 27 babies.

With them it's a question of having patience. Good luck!!

Thanks very much Bushbaby. I wasn't expecting any so I will be over the moon with whatever comes our way. Is there anyway of estimating an expected birth date from the photos? Just want to be sure I have everything in place.

When last did she shed? Did she have a "bubble" at other time, or is this the first time you have noticed it?

It is usually 105 -120 days after the Post Ovulation shed or about 60 days from the mid term shed.

The pictures do not help at all.

That bubble is right as high as it is there. As they get further along with the whole process the "bubble" will move down to the bottom of the body.

This does look like an Ovulation and not a "pregnancy" swell. Take note of when she sheds & it should be around 60 days till the next shedding.

Nope 60 days till the next shedding and then another 45 to 65 till she has babies.

Offer her small food items every week although she will probably not eat until she has dropped babies.

If she eats, keep on feeding her, but if she doesn't, you can offer her smaller food. Some will take food a week or so before birthing as well.

Thanks Bushbaby. She did actually take a 250 gram rat last weekend compared to the usual 500 gram rats she eats. I will keep offering her a meal every 2 to 3 weeks.
