On-farm processing of value-added dairy products can be a way for small dairy farms to diversify production and increase revenue. This article examines characteristics of three groups of Vermont farmers who have grass-based dairy farms—those producing value-added dairy products, those interested in such products, and those not interested in such products—and their needs for information and assi...

There is worldwide public expectation that responsible governments will protect their citizens from hazards from which they are unable to protect themselves. Meat and dairy products can pose substantial risks, and international trade in these products relies heavily on government-controlled food safety programmes, assurances and certification as to freedom from unacceptable levels of hazards.

The paper investigates the implications of hedonic pricing of components, with an application to the dynamics of dairy product prices. A conceptual model of hedonic pricing is developed under a Leontief technology, showing how commodity prices reflect the underlying value of their components. Implications for the existence of cointegration relationships among commodity prices are derived. An ap...

This method was relatively less effective for the detection of coliforms in many ...

Seven healthy subjects received, after an overnight fast, a single 200-mg oral dose of norfloxacin with water, whole milk, and unflavored yoghurt.

Taking of norfloxacin with these liquid dairy products should be avoided.

We investigated the effect of stage of pregnancy on estimates of breeding values for milk yield and milk persistency in Gyr and Holstein dairy cattle in Brazil. Test-day milk yield records were analyzed using random regression models with or without the effect of pregnancy. Models were compared using residual variances, heritabilities, rank correlations of estimated breeding values of bul...
