Antimicrobials for cattle
Welcome to the page about Antimicrobials for cattle of Engormix; a source of knowledge on Antimicrobials for cattle.
In Spain, the beef fattening system is an intensive system where calves are commonly housed in partially open barns with straw bedding and 40% of the calves, mainly males, are from dairy origin (surplus calves). These calves are transported by road for long hours (up to 3-5 days) from their dairy origin farms to the rearing farm where these calves are fed low amounts of milk replacer for 6-8 weeks and concentrate and straw ad libitum in separate feeders from very young ages with a resulting...

1. Introduction A major challenge for public health is the increment in resistance to common antimicrobial compounds. Consequently, antimicrobial resistance (AMR) is regarded as a priority, and the main goals of the World Health Organization (WHO) aim at containing this problem [1,2]. Microorganisms can develop resistance to antimicrobial agents. In bacteria, for instance, antibiotic resistance traits can arise from mutations in the genome [3], which can then be mobilized...

1. Introduction Antimicrobial resistance (AMR) is one of the top 10 global threats to public health and is thought to be partly driven by the widespread use of antibiotics in food-producing animals (WHO, 2021). Globally, a greater proportion of the tonnage of all antibiotics sold are for use in food-producing animal sectors compared to for use in humans (Van Boeckel et al., 2017). In 2017, an estimated 93 million kilograms of active ingredient were sold worldwide for use in...

Introduction Antimicrobials, including antibiotics, antivirals, antifungals, and antiparasitics, are used to prevent and treat infections in humans, animals, and plants. 1 Microbes can become resistant to antimicrobials as a result of ineffective or prolonged antimicrobial treatment. This resistance may be “innate” owing to the slow and long evolutionary process that microorganisms undergo to adapt to changing environmental conditions; this adaptation is...

Author: ballyabio Just like humans, dairy cows are also prone to a number of infectious diseases and health conditions. Timely diagnosis of diseases and effective treatment strategy is very much important for the well-being animals and significant growth of dairy business. Overall profitability of the dairy business highly depends upon how you keep cows healthy and free from diseases.

INTRODUCTION Haemorrhagic septicaemia (HS) is a disease of cattle and buffalos (Abdulkadir, 1989) caused by 1 of 2 serotypes of Pasteurella multocida, designated B:2 and E:2 (FAO, 2015; IIL, 2015). The disease in cattle is prevalent in the tropics, particularly in the equatorial region of South East Asia and Africa, where outbreaks mostly occur during the rainy season (Dhanda, 1966; Anosa and Esoun, 1975). In Nigeria, HS in cattle was first reported in Sokoto, Bauchi,...

General After 40 years of giving the entire herd blanket dry cow therapy (DCT), some dairy farms in Israel have transitioned to “selective drying-off” (SDCT) at the start of the dry period. This change is a welcome one since it once again emphasizes the recognition of the necessity of minimizing the use of antibiotics, without of course harming the health and well-being of the animals. Years ago, in Northern Europe and America, a number of countries issued...

Introduction Mastitis is a worldwide problem of dairy production characterized by physical and chemical changes in milk. The microbiological and pathological changes in the glandular tissue of the udder alter the quality of milk. Mastitis has emerged as a health hazard responsible for the economic losses in dairy animals (Cady et al., 1983). It has been noted that amongst all diseases, mastitis is most expensive and ranks at the highest point list of disease of dairy animals by...

Background Salmonella is a diverse bacterial species comprising over 2600 serotypes [1]. Salmonella commonly colonizes a range of animal hosts such as mammals, amphibians, reptiles, birds and insects [2]. There are 2 species of Salmonella: Salmonella enterica and Salmonella bongori. Salmonella enterica is further classified into 6 subspecies (Salmonella enterica subspecies enterica, S. enterica Subspecies salmae, S. enterica Subspecies arizonae, S. enterica Subspecies...

Introduction Control of mastitis caused by Streptococcus agalactiae and Staphylococcus aureus has resulted in reductions in bulk tank somatic cell count (SCC) but many herds continue to struggle with treatment of clinical mastitis caused by environmental pathogens. On many modern dairy farms, mastitis is caused by an increasingly diverse group of opportunistic pathogens (Figure 1). Common environmental mastitis pathogens...

Introduction Mastitis remains the most common disease of dairy cows and treatment or prevention of this disease is the most common reason that antibiotics are administered to cows (Pol and Ruegg, 2007, Saini et al., 2012). Mastitis is detected by inflammation that is caused by infection by microorganisms and occurs in both clinical and subclinical forms. Milk obtained from quarters of cows with subclinical mastitis looks...

Introduction For several decades, the use of sub-therapeutic levels of antibiotics in animal feeds has been a common practice in many countries in order to improve growth performance and prevent from the adverse effects of pathogenic and non-pathogenic enteric microorganisms. However, there are increasing concerns for the public health about the consequences from the use of antibiotics in livestock [1]. The risk of...

INTRODUCTION Supplementation of feedlot diets with either lasalocid or monensin may improve gain efficiency (Berger et al., 1981; Delfino et al., 1988). This effect has been attributed, in part, to shifts in ruminal fermentation patterns toward reduced methane energy loss (Bergen and Bates, 1984; Russell and Strobel, 1988). Both monensin and lasalocid supplementation may decreases dry matter intake in feedlot cattle...

Recently, livestock producers and veterinarians have been hearing about changes coming in the way antibiotics are used in food animals. In mid-December, the Food and Drug Administration (FDA) published a final “guidance for industry” that starts the clock running on some of these changes. Initially, it’s the animal health companies that will be adjusting their practices -- adjustments that will eventually make their way down to the people who...
