Growing evidence suggests that the consumption of dairy products may contribute to a reduced incidence of cardiovascular risk factors, such as obesity, dyslipidemia, and type 2 diabetes. The fatty acid composition in milk fat, the duration of ripening, and the complexity of the food matrices are important factors that may interfere with the physiological impact. In this study, we treated geneti...

2. Maximal lactational response in different experiments depended upon wha t Mg source was supplemented and the milk production level (stage of lactation) of cows . For midlactation cows supplemented with feed grad e magnesium phosphate, .48% total dietary Mg resulted in greatest milk yield . When midlactation cows were provided additional dietary Mg as Mg O maximal lactational response was obt...

An animal model with a REML algorithm was used to estimate variances of additive genetic effects and interaction effects of sire and herd. Milk and fat yields were analyzed for first, second, and third lactations of Holsteins from California, New York, and Pennsylvania. Twenty samples of data were used in the study: 10 from California, 4 from New York, and 6 from Pennsylvania. Mean number of la...
