Simply feeding milk or milk replacer isn’t enough in developing calves. Their rumens need a separate source of pure water to feed the fermentation process that promotes rumen development. Research in a 5-week comparison period found calves getting water by a bottle consumed an average of 1.4 quarts of water per day, compared to 0.2 quarts for the bucket group.

Knowing open cows more important than knowing pregnant ones
The most important controllable component of any breeding program is to identify your open cows, says Donna Amaral-Phillips, PhD. The faster open cows are identified, the sooner they can be rebred. Lost pregnancies are not just frustrating. They often cause long-term financial impacts. The more cows with extended days open, the greater the total cost.” - Donna Amaral-Phillips, … [Read more...]
