Montbéliarde (MO) × Holstein (HO) and Viking Red (VR) × HO crossbred cows were compared with pure HO cows in 8 large, high-performance dairy herds in Minnesota. All cows calved for the first time from December 2010 to April 2014. Fertility and survival traits were calculated from records of insemination, pregnancy diagnosis, calving, and disposal t...

The objective of this study was to identify genomic regions and candidate genes associated with feed efficiency in lactating Holstein cows. In total, 4,916 cows with actual or imputed genotypes for 60,671 single nucleotide polymorphisms having individual feed intake, milk yield, milk composition, and body weight records were used in this study. Cow...

Sole hemorrhages result from disruption to normal claw horn formation and are caused by a variety of internal and external factors. Evidence suggests that they are painful, although they do not usually cause clinical lameness and are difficult to detect by observing cow gait. Little is known about how or whether sole hemorrhages affect the cow syst...

Dried distillers grain with solubles (DDGS) is an alternative source of feed protein for dairy cows. Previous studies found that DDGS, based on grains other than corn, can substitute for soybean meal and canola cake as a dietary protein source without reducing milk production or quality. As societal concerns exist, and in many areas strict regulati...

Mycoplasma bovis can have significant consequences when introduced into immunologically naïve dairy herds. Subclinically infected carrier animals are the most common way that M. bovis is introduced into herds. Although M. bovis udder infections can be detected by milk sampling lactating animals before their introduction, currently, no definitive wa...

Reticuloruminal pH has been linked to subclinical disease in dairy cattle, leading to considerable interest in identifying pH observations below a given threshold. The relatively recent availability of continuously monitored data from pH boluses gives new opportunities for characterizing the normal patterns of pH over time and distinguishing these ...

The objectives of this study were to explore Canadian dairy producers' attitudes toward reproductive performance and challenges they perceive to be related to reproduction and reproductive management practices. A survey in both English and French was developed, validated, and administered to Canadian dairy farmers between March and May 2014 to coll...

Streptococcus thermophilus plays important roles in the dairy industry. Streptococcus thermophilus KLDS SM could produce a high amount of exopolysaccharides (EPS). To understand the possible link between the genotype and the phenotype regarding EPS, the complete genome of S. thermophilus KLDS SM was sequenced and investigated in silico for genes re...

Using soluble fiber sources in starter and grower feeds for dairy calves less than 4 mo of age is common to reduce costs compared with including traditional cereal grains. Beet pulp (BP) contains relatively high concentrations of pectin compared with other fibrous feed ingredients and has been shown to be an acceptable replacement for corn in adult...

An acute case of clinical mastitis in a Holstein cow from second lactation is reported here. A milk sample from the affected quarter was cultured on 5% bovine blood agar and incubated at 37°C for 72 h. After 24 h of incubation, numerous colonies of yeast were observed: the Candida characteristic was not detected by CHROMagar Candida (Difco, Frankli...
