Abstract

Although the over-use of antibiotics during food animal production is a potential driver of antimicrobial resistant microorganisms (ARMs), a high prevalence of cefotaxime resistant bacteria (CRB) has been observed in grazing animals raised without antibiotic supplementation. In this cross-sectional ...

Abstract

Here we report a previously undescribed coat color phenotype in Holstein cattle. Larson Blue Holsteins, located on a dairy in south Florida, exhibit a coloration pattern that is similar to that of black and white or red and white Holsteins except that, instead of being black or red, darker regions...

AbstractFull Text

Nutrient deficiency often occurs in animals provided forage-based diets due to seasonal variation in forage quality and quantity. This nutrient deficiency has been shown to impact reproductive performance of cows, but also fetal development. Maximal placental growth, differentiation, and...

Abstract

The objective was to evaluate the effect of housing type on health and performance of preweaned dairy calves. One hundred calves, Holsteins (HO) or Holstein-Jersey crosses (HJ), were randomly assigned to a Calf-Tel (L. T. Hampel Corp., Germantown, WI) polyethylene hutch exposed to direct sun light...

Abstract

Bovine viral diarrhea virus (BVDV) is a ubiquitous infectious agent affecting cattle worldwide. Animals that are born persistently infected (PI) with BVDV are considered the primary viral reservoirs in cattle herds and are capable of shedding copious amounts of virus into the environment. The...

Abstract

Vitamin D is critical for the growth and development of calves and positively contributes to immune function of cattle. Serum 25-hydroxyvitamin D (25(OH)D) concentrations above 20 ng/mL have traditionally been considered adequate for growth and development of cattle, but recent evidence has...

Abstract

The fertility of lactating Holstein cows is severely reduced during periods of heat stress. Despite this reduction in fertility, however, some inseminations conducted during heat stress result in successful pregnancies from which heifer calves are born. Many of these heifer calves are retained and...

Abstract

Reproductive efficiency is arguably the most economically important trait in commercial beef cattle production, as failure to achieve pregnancy reduces the number of calves marketed per cow exposed to breeding. Identification of variation in the genome with predictive merit for reproductive success ...

Abstract

This study was initiated to evaluate performance and patterns of cow traits and blood metabolites of 3 breeds of cows grazing bahiagrass (Paspalum notatum Flügge) pastures in central Florida. Purebred cows (n=411) of either Angus (Bos taurus), Brahman (Bos indicus), or Romosinuano (Bos taurus)...
