Few years back I quit my job and came into dairy farming. Biggest problem I face is cattle not conceiving. We give sperm with doctor or bull and then wait two months and again call doctor to check if she is pregnant or not. Like humans have small pregnancy test kit at home same thing for cattle also saves so much time and money. And like we have smartwatch to track our health same way ear tags for cattle that tracks activity feeding temperature helps detect problems early. Farmer should not wait for doctor visit to know basic things about his own cattle.
