    Recommendations have varied for the optimal age at first calving in order to maximize milk production and profitability.  However, due to variability in bodyweight, there is likely no optimal age at first calving and perhaps we should be focused on optimal bodyweight at first calving instead.  Several factors should be considered when determining what optimal means for a dairy farm, listen to today’s podcast to hear about which factors were considered by researchers.

    Dairy Management Inc. has announced a goal for the dairy industry to achieve carbon neutrality by 2050.  We now have to figure out innovative strategies to make that possible.  One strategy we are exploring today is a seaweed based feed additive that has shown promise in reducing methane emissions.

    377-Hypocalcemia in Dairy Cattle

    377-Hypocalcemia in Dairy Cattle
    Hypocalcemia in dairy cattle is not a new phenomenon, however, researchers are making progress on understanding nutrition and management strategies to mitigate the change in calcium that occurs around calving. Dr. Jesse Goff, a leading researcher on hypocalcemia, has recently provided an update on hypocalcemia in dairy cows. This episode of the Purdue Dairy Digest will talk about an update from Dr. Jesse Goff on hypocalcemia.

    376-In utero heat stress

    376-In utero heat stress
    As we experience hot weather, cows are subject to heat stress. While we observe reduced milk production and reduced reproductive success in lactating cows, there are also negative consequences for dry cows that experience heat stress during late gestation. We will be discussing a journal article that looked at the long term effects of daughters and granddaughter from heat stressed dams.

    375-High Class III prices may not reflect higher milk checks

    375-High Class III prices may not reflect higher milk checks
    No one said that milk pricing was easy and certainly the volatility of milk prices recently have made us all question what we know about milk markets.  We have seen very high Class III milk prices recently however, there are some factors that make prevent dairy farmers from seeing the full benefit of high Class III prices in their milk checks.  Listen to the podcast to hear more about what is happening with milk pricing today.

    #371-Should I start feeding my calves milk instead of milk replacer?

    #371-Should I start feeding my calves milk instead of milk replacer?
    In this podcast, Dr. Tana Dennis will discuss what a producer needs to consider if they are going to start feeding milk to calves instead of milk replacer. While there is a surplus of milk, some farms may be tempted to feed their calves milk instead of milk replacer. This may make sense economically however, there are some important things that farms need to be able to manage before making this switch.
