Adapted by Noelia Silva-del-Ro and Carol Collar, UCCE Tulare and Kings Counties We have recently summarized BTM quality and pathogen culture data from California dairies.

Adapted by Jed Asmus, Independent Nutritionist and Jennifer Heguy, UCCE Stanislaus and San Joaquin Counties Our last article talked about the cost of feeding excess. This follow up article expands upon the topic by explaining the logic and lost opportunities associated with over supplying nutrients.

Adapted by Noelia Silva-del-Ro, UCCE Tulare County What is Milk Urea Nitrogen? Milk urea nitrogen (MUN), the concentration of urea in milk, is a tool to monitor the efficiency of crude protein utilization in dairy cows. In the rumen, microbes degrade dietary protein to ammonia.

Adapted by Betsy Karle, UCCE Glenn & Tehama Counties Nothing seems to strike fear like a call from the media. In recent months, they have been none too kind to our industry, but as dairy producers you really do have the opportunity to tell your story.

Adapted by Alejandro R. Castillo, UCCE Merced County Feed efficiency can be defined as the amount of milk produced per unit of feed intake during a normal lactation, and will be affected by body weight changes and environmental factors (e.g. heat stress).

Adapted by Noelia Silva-del-Ro, UCCE Tulare County, Dennis Craig and Vernal Gomes of Mycogen The dry matter of the crop standing in the field can be estimated by evaluating the greenery of the canopy, breaking down the stalk and examining the kernel milk line.

Adapted by Alejandro R. Castillo, UCCE - Merced County Recent water use estimations in California dairy farms indicate 40 to 50% of water is used for animal cooling and consumption.

Adapted by Larry Schwankl, Allan Fulton, Terry Prichard - UCCE There are two important components of irrigation water management: (1) knowing when and how much water to apply to the crop, and (2) irrigating so that most of the applied water is available to the crop.
