The effect of the phenotypic combination of genetic variants κ-CN/β-Lg on the contents of technologically and nutritionally important components of milk as well as technological properties of milk was...
The results of chemical and microbial analyses of raw milk samples coming from organic and conventional farming systems were statistically compared. The samples were analysed during a twelve-month per...
The purpose of the present study was to estimate the effect of total blood plasma calcium (TBPCC) concentration at calving on milk yield in dairy cows. Data originated from 153 dairy cows in 27 herds ...
Eighteen cows had been selected for their responsiveness to psychological stress during the first lactation and were classified as having low (n = 10) or high (n = 8) cortisol concentrations in respon...
Fifteen multiparous Holstein cows averaging 39 DIM were used in a replicated 5 x 5 Latin square design to compare roasted soybeans and animal by-products as supplements for increasing the RUP content ...
Multiparous Holstein cows (n = 18) were bred artificially to the same Holstein bull and then slaughtered at times from 190 to 270 d postmating to assess S and Se accretion in the fetus and nonfetal co...
Six ruminally cannulated cows were used in an experiment with a 3 x 3 Latin square design. Three all forage diets—alfalfa silage, alfalfa hay, or corn silage plus 2.2% urea (DM basis)—were fed for ad ...
Logistic regression was used to examine the association between milk yield and disease. We studied 8070 cows of second or higher parity from 25 New York State Holstein herds, calving between June 1990...
The associations among milk yield, days open, and days to first breeding were studied in 15,320 Holstein cows, calving between June 1990 and November 1993, in 26 New York herds. Survival analysis, inc...
In the lactating cow, galactopoiesis is stimulated by treatment with recombinant bovine somatotropin (bST) and by an improved plane of nutrition. The present study determined the interaction between t...
Twenty-four lactating dairy cows, averaging 30.0 kg/d of milk and 159 d of lactation, were used to study the effect of feed intake and growth hormone-releasing factor in a 2 x 2 factorial arrangement....
This experiment examined the effect of complete diets composed of 60% grass silage and 40% concentrate based mainly on beet pulp, ground wheat, wheat treated with NaOH, or ground corn on milk producti...
Four lactating cows equipped with rumen and duodenal cannulas were fed a diet of grass silage and concentrates containing either 12.4 or 17.2% CP (DM basis) in a change-over design. Additional protein...
Forages (corn silage and alfalfa hay) were sprayed with liquid enzymes prior to combining with a concentrate to form a total mixed ration (50% forage:50% concentrate, dry matter basis) and fed to lact...
The associations between occurrence of diseases, milk yield, and body condition score on conception risk after first artificial insemination (AI) were analyzed in an observational study on a convenien...
