With heat and drought taking its toll on dairy farms, this could be the last time in 29 months that the U.S. Department of Agriculture reports a milk production increase.

On July 19, the USDA reported milk production in June was up 1 percent compared to June 2011 in the top 23 dairy states.

It’s a smaller growth rate than seen previously this year. In April, production on a year-over-year basis was up 3.5 percent and in March it was up 4.3 percent.

The states showing the largest increases in June were: Colorado (5.5 percent), Florida (5.2 percent), and Utah (5.1 percent).

In the top 23 dairy states, the number of milk cows grew 57,000 head from June 2011 to June 2012. However, the number of cows was down 14,000 head from the previous month.

Meanwhile, milk per cow increased 7 pounds on a year-over-year basis.

One last gasp for milk production increases?
