Methylmalonic Acid in Low-Fat Milk Syndrome

Fatty Acid Nutrition and Milk Fat Depression

Milk fat concentration is variable and very responsive to many factors including genetics, season of the year, and physiological state, but is especially responsive to diet. Synthesis of milk fat is an energy demanding process, but also represents a significant portion of the economic and nutritional value of dairy products. First described over one and a half centuries ago, diet-induced milk f...

Effect of Feeding Canola or Sunflower Seeds on Conjugated Linoleic Acid Enrichment in Cow’s Milk Fat

Two experiments studied the effects of canola or sunflower seed supplementation on conjugated linoleic acid (CLA) concentration in milk fat of lactating cows. In each experiment, only eight cows in early lactation were available to assign to one of two treatments in a completely randomized design and were fed individually for 12 wk. Experiment 1 compared similar diets with or without the additi...

Conjugated Linoleic Acid: a Potent Anticarcinogen Found in Milk Fat

As an important source of nutrients, milk provides high quality protein, energy, calcium, and a variety of vitamins and minerals. Recent research has focused on altering the fat and protein content of milk and other dairy products in order to improve the nutrient content of these foods so that they more aptly reflect current dietary recommendations and trends. Conjugated linoleic acids (CLA), a...

Commercial Low-Fat Milk Markedly Stimulates Mammary Carcinogenesis in Rats

Commercial cows’ milk contains considerable amounts of estrogens. This study assessed the effect of commercial low-fat milk on the development of 7,12-dimethylbenz(a)anthracene (DMBA)-induced mammary tumors in rats. Eighty six-week-old female Sprague-Dawley rats received a single oral dose of 5 mg DMBA. Twenty-four hours later, the animals were divided into 4 groups of 20 animals each and given...
