Past research in dairy cattle nutritional management has focused almost exclusively on the nutritive aspects of the diet, resulting in many discoveries and improvements in dairy cow health and production. Despite many advances this field we are still faced with several challenges associated with feeding dairy cattle. Recent field observations suggest that housing and management can play as large of a role as nutrition in the performance and health of...

Introduction Bovine lameness is an important condition in commercial dairy and beef operations worldwide. Its economic impacts include decreased reproductive performance and milk yield and increased culling rates, milk losses and labor. One relatively new finding in the field of lameness is the non-healing lesions (NHL) such as toe necrosis (Blowey, 1999; Tozzo, 2000) and wall ulcers (Holzhauer, 2008; Cook and Burgi, 2008). These lesions typically are unresponsive or poorly...

Introduction • Questions have risen on impact of many hoofbath chemicals on human health and the environment, and also concerns about water usage. • Topical spray disinfectant solutions are an interesting alternative to hoofbaths because they address those concerns. • While 1 L/cow disinfecting solution is standard recommendation in a hoofbath treatment, only 50 mL/cow would be required if spraying. • This study evaluated the preventive...

The GIT, or rather the gastrointestinal tract, is the organ of the all organism mostly colonized by the microbial population: it hosts more than 70% of all the microbes of the animal body and forms the gastrointestinal microbiome, consisting of bacteria, yeasts, fungi and viruses. The viruses present,...

A cross sectional study was undertaken to determine the prevalence and intensity of parasitic infections in dairy cattle in the high tropics of Colombia. A total of 1003 rectal samples were collected from dairy cows at 29 farms between May and June 2014 to represent the number of farms, age groups, and size of the 65,000-cow population in the municipality of San Pedro de los Milagros. Coprological techniques were used to detect gastrointestinal nematodes, liver flukes, coccidian oocysts, and...

Introduction The southern cattle tick Rhipicephalus ( Boophilus ) microplus (Acari: Ixodidae) is a persistent vector for infective tick-borne diseases in cattle such as babesiosis and anaplasmosis (Cossio-Bayugar, Miranda, and Holman 2005). The endemic nature of this bovine blood-sucking ectoparasite is considered an obstacle for development of the cattle industry in tropical and subtropical cattle grazing areas world-wide (Nu ez, Mu oz-Cobe as,...

Background Mycobacterium avium subsp. paratuberculosis (MAP) is a slow-growing bacterium that causes Johne’s disease, a wasting disease in ruminants and other animals. A common test for Johne’s disease is the serum antibody ELISA test which monitors the humoral immune response of the animal following MAP exposure. However there are well known limitations of this test, for example the sensitivity can be...

INTRODUCTION Adequate rest has been positively associated with productivity, health, and welfare of dairy cattle. When access to stalls is restricted, cows prioritize lying down over feeding (Munksgaard et al., 2005), and preventing cows from lying down induces stress (Cooper et al., 2008). As a consequence, measures of lying behavior, such as the daily duration and the frequency and duration of lying bouts, is a measure of cow comfort (Haley et al., 2001; Rushen et al.,...

Introduction The transcriptome is the momentary sum of all DNA transcribed in a cell. Classically, the transcriptome included the measurement of each of the ribosomal RNA, messenger RNA (mRNA), and transfer RNA. These include a relatively small portion of the whole genome.1 The rest of the DNA was considered, until recently, not to be transcribed.1 The accumulation of data in the last decade or so has provided vast...
