  1. Short communication: Genetic evaluation of stillbirth in US Brown Swiss and Jersey cattle.

    Journal of Dairy Science 97(4):2474 (2014) PMID 24508434

    Stillbirth (SB) often results in reduced milk yield, compromised reproductive performance, and decreased dam longevity. Corrective mating can be used as a short-term solution to the problem, but long-term improvement of the population requires the routine calculation of genetic evaluations. Breeding...
  2. Interactions of alfalfa hay and sodium propionate on dairy calf performance and rumen development.

    Journal of Dairy Science 97(4):2270 (2014) PMID 24508441

    The objective of this experiment was to investigate the effects of different levels of alfalfa hay (AH) and sodium propionate (Pro) added to starter diets of Holstein calves on growth performance, rumen fermentation characteristics, and rumen development. Forty-two male Holstein calves (40±2kg of bi...
  3. Urea-N recycling in lactating dairy cows fed diets with 2 different levels of dietary crude protein and starch with or without monensin.

    Journal of Dairy Science 97(3):1611 (2014) PMID 24377801

    Rumensin (monensin; Elanco Animal Health, Greenfield, IN) has been shown to reduce ammonia production and microbial populations in vitro; thus, it would be assumed to reduce ruminal ammonia production and subsequent urea production and consequently affect urea recycling. The objective of this experi...
  4. Use of micellar casein concentrate for Greek-style yogurt manufacturing: Effects on processing and product properties.

    Journal of Dairy Science 97(3):1259 (2014) PMID 24440261

    The objective of this work was to develop and optimize an alternative make process for Greek-style yogurt (GSY), in which the desired level of protein was reached by fortification with micellar casein concentrate (MCC) obtained from milk by microfiltration. Two MCC preparations with 58 and 88% total...
  5. Fine mapping of a quantitative trait locus for bovine milk fat composition on Bos taurus autosome 19.

    Journal of Dairy Science 97(2):1139 (2014) PMID 24315323

    A major quantitative trait locus (QTL) for milk fat content and fatty acids in both milk and adipose tissue has been detected on Bos taurus autosome 19 (BTA19) in several cattle breeds. The objective of this study was to refine the location of the QTL on BTA19 for bovine milk fat composition using a...
  6. Effects of milk replacer feeding strategies on performance, ruminal development, and metabolism of dairy calves.

    Journal of Dairy Science 97(2):1016 (2014) PMID 24342682

    Performance, rumen development, and metabolism of male Holstein calves (n=54) were evaluated according to 1 of 3 liquid feeding strategies: 4 L of milk replacer (MR)/d until 60 d old (4L-60d), 6L of MR/d until 29 d old and 4 L/d from 30 to 60 d (6L-29d/4L-60d), or 6L of MR/day until 60 d old (60d-6L...
  7. Short communication: Effect of blackberry and pomegranate oils on vaccenic acid formation in a single-flow continuous culture fermentation s...

    Journal of Dairy Science 97(2):1067 (2014) PMID 24342694

    A single-flow continuous culture fermenter system was used to study the effect of blackberry and pomegranate oils on vaccenic acid (trans-11 C18:1; VA) formation. Four continuous culture fermenters were used in a 4×4 Latin square design with 4 periods of 10d each. Diets were (1) control (CON), (2) c...
  8. Production of galactooligosaccharides using a hyperthermophilic β-galactosidase in permeabilized whole cells of Lactococcus lactis.

    Journal of Dairy Science 97(2):694 (2014) PMID 24359820

    Galactooligosaccharides (GOS) are novel prebiotic food ingredients that can be produced from lactose using β-galactosidase, but the process is more efficient at higher temperatures. To efficiently express the lacS gene from the hyperthermophile Sulfolobus solfataricus, in Lactococcus lactis a synthe...
  9. Short communication: Maternal heat stress during the dry period alters postnatal whole-body insulin response of calves.

    Journal of Dairy Science 97(2):897 (2014) PMID 24359830

    Heat stress during the dry period not only negatively affects a cow's performance but also affects her offspring. Previous studies indicate that calves born to cows heat-stressed during late gestation have lower birth weight but similar overall weight gain during the prepubertal period compared with...
  10. Evaluation of selective dry cow treatment following on-farm culture: Risk of postcalving intramammary infection and clinical mastitis in the...

    Journal of Dairy Science 97(1):270 (2014) PMID 24183691

    The objective of the study was to evaluate the utility of a Petrifilm-based on-farm culture system when used to make selective antimicrobial treatment decisions on low somatic cell count cows (<200,000 cells/mL) at drying off. A total of 729 cows from 16 commercial dairy herds with a low bulk tank s...
