Does anyone out here have experience with these long shot pole syringes that and interchangeable with a calf catch hook? I am looking into getting one, just wanted to know if they are worth it. I have a heifer that the neighbors bull got to and I was wondering if it would discharge the Lut quick enough if Istuck her in the pasture before she ran away. Penning these heifers would involve penning 2 other pastures of cows to get them to the pens, and I don't really want to do that, and leaving her bred is not an option. Thanks for any input.
