The "loss of all the future experiences of the babies" bit doesn't apply here. Animals stay creatures without moral worth through their whole lives, and so the "suffering and death of the animals" here has no moral value.

Pigs can meaningfully play computer games. Dolphins can communicate with people. Wolves have complex social structures and hunting patterns. I take all of these to be evidence of intelligence beyond the battery farmed infant level. They're not as smart as humans but it's not like they've got 0 potential for developing intelligence. Since birth seems to deprive your of a clear point in this regard - what's your criteria for being smart enough to be morally considerable, and why?
