Putting embryo in a cow

[darcelina4]

I have a mixed herd but am going more to red Angus. I have some registered heifers. I have a Jersey nurse cow that I raised from a bottle calf. She is a small stature compact cow that only weighs 800. She is bred to calve in march with her third calf. She has had 2 calves that were 1/2 beef shorthorn. Heifer was 77 pounds, bull was 67. She spit them out and the calves were nursing in under 30 minutes. She is not a big milk producer but can raise 2 fat calves at a time. I am wondering if it would be worth the expense to try an put a registered red Angus embryo in her. I haven't gotten far enough to look into the cost so some of you could guide me with that info. I know this would be for a 4th calf and people like to implant heifers for fertility but she has always been a good fertile cow calving every march. So give me your opinions please.
