Game is very laggy with lots of animals

When I played in 1.17 I built a little farm(close next to my house and mine)I can't say the game when smoothly but I was playable. But when I updated to 1.18 I started having troubles mining, placing block(in other words: doing anything..) I thought I had render or chunks problems, but after creating a copy of my world and experimenting I found out that the problem  was that I had "a lot" of animal... Soo I was wandering if there's some kind of limit's for mods being in a chunk or is my PS4 having problems or if this is a actual problem😐🤔
