Pneumonia of calves is a respiratory disease caused by the entry of bacteria and respiratory viruses into the body of calves, which occurs at the age of two to five months, and is more common in closed places and in the winter season. The best prevention of this pneumonia disease in calves is to give colostrum to calves. ...

Diarrhoea is a multifactorial disease entity that can have serious financial and animal welfare implications in dairy herds. It has been estimated that 75% of early calf mortality in dairy herds is caused by acute diarrhoea in the pre-weaning period Diarrhoea is a common complaint in cattle and young ruminants (particularly in the first few months of life). Many of the pathogens and management practices that cause diarrhoea in...

Chronic Respiratory Disease (CRD) is of high economic importance as this causes heavy production loss & mortality. Mycoplasma gallisepticum(MG) & Mycoplasma Synoviae(MS) is involved in polymicrobial “chronic respiratory disease” of chicken. Various antibiotics are used for management but pose the threat of MDR, & human food safety risks. Hence, the need of the hour is to find suitable alternatives for alleviation of sub-clinical infections and prevention of local...

Introduction Bovine respiratory disease (BRD) is the most important cause of economic loss of the beef industry in many parts of the world (12, 14, 26). It is a multifactorial condition that involves host and environmental factors, and several viruses and bacteria. The most common viruses associated in cattle with BRD are bovine herpesvirus (BHV-1), bovine parainfluenza virus 3 (BPIV-3), bovine viral diarrhea virus 1 and 2 (BVDV-1/2), bovine respiratory syncytial virus (BRSV)...

Introduction Evaluation of serum or plasma electrolytes is important part of the blood chemistry profile in cattle. Potassium (K+) and sodium (Na+) are the major intracellular and extracellular cations, respectively.1 Chloride (Cl) is the major anion in extracellular fluid.1,2 Changes in serum/plasma chloride concentration are generally parallel to those of sodium. ...

On 27 July 2015, Germany’s veterinary authorities notified the European Commission via an ADNS and OIE announcement that a highly pathogenic avian influenza H7N7 had broken out in a poultry flock of 14,104 layer hens in Herzlake Municipality, in the rural district of Emsland, Lower Saxony (see the flags on the map below).
An egg-laying decline, reduced food intake and a higher mortality rate were observed on 24 July. For these reasons, samples were taken to be analysed for...

Shipping Fever, also called bovine respiratory disease complex or pneumonic pasteurellosis, is an important respiratory disease of cattle that appears in animals from six months of age, usually after suffering stress caused by transportation, which may include mixing and grouping with other batches of animals of the same age during transportation, in the market and arrival at the finishing farm (Caswell, 2006; Kasimanickam, 2010). As a result of this...

Summary Bluetongue (BT) is an infectious non contagious, insect born viral disease of sheep and other ruminants. The clinical diagnosis of bluetongue is often difficult due to the marked variations in the severity of the symptoms and lesions. The primary problem caused by BTV in enzootic areas was the decrease in lamb and calf production. VMRD's competitive ELISA test kit was used to detect bluetongue group specific antibodies in 184 serum samples collected from apparently...

Introduction Infectious bovine rhinotracheitis is worldwide in distribution caused by bovine herpes virus-1 (BHV-1), however, IBR was reported for the first time in India by Mehrotra et al. (1976). It is one of the most prevalent respiratory and reproductive viral disease of cattle. Sinha et al . (2003) and Malmarugan et al . (2004) reported the IBR prevalence of 2.75 per cent and 81.0 per cent in...

Respiratory disease is the second leading cause of death losses (scours is the first) in un-weaned heifer calves. Respiratory problems have increased by 34 percent in the last 20 years, causing nearly 21 percent of all newborn calf losses (NAHMS 2007). Heifers that survive continue to perform poorly as adult cows. In order to prevent this costly problem, it is important to address both determinant and predisposing causes. PREDISPOSING CAUSES...

Bovine Viral Diarrhea Virus (BVDV) is a costly disease that affects cattle and other ruminants. The virus has many nasty effects, including fever, diarrhea, respiratory and reproductive disease, abortion, birth defects and death. The national economic impact of the disease has not been assessed in the United States, although one document from the U.S. Department of Agriculture (USDA) Animal and Plant Health Inspection Service (APHIS) estimates that acute BVDV could result in losses of $50 to...

Bovine respiratory disease continues to be the leading cause of illness and death loss from weaning through finishing. There is no objective method to evaluate a live animal’s severity of sickness or their response to treatment. A pilot study was conducted at a commercial feedyard to evaluate the ability of near infrared spectroscopy to differentiate between cattle identified as healthy and those identified as having undifferentiated Bovine Respiratory Disease (BRD). At processing, 215 randomly...
