Oxidative stress is a normal occurrence during the immune system’s inflammatory response to infection or injury. Inflammation plays a vital role in the body’s response to pathogens and tissue damage. However, considerable evidence now points to oxidative stress from chronic inflammation as a contributing factor in a number of health and production disorders in cattle. Research suggests that oxidative stress in dairy...

1. Introduction Inflammation and pain in dairy animals is manifestation of numerous disease related conditions influencing the overall animal well-being as well as their productive and reproductive capabilities. Mastitis is defined as the inflammation of the mammary gland [1] and udder tissue and is one of the major endemic diseases of dairy cattle [2]. It typically occurs as an immune response against the bacterial...

Introduction The milk and other products of dairy industry are integral part of food chain. It is estimated that population of planet earth is increasing day by day and will reach nine billion in 2040-2050 (Anonymous, 2005). So, demand of milk is increasing with ever increasing population (Buzby et al., 2006; Bilal, 2008; Serbester, 2012). Although there is an increasingtrend of milk production since last several years...

Introduction Lactation in the dairy cow is influenced by various management factors as well as the milking equipment. Milking efficiency is a combination of proficiency of the milker, operation of the milking equipment, and cow factors including udder shape, temperament and physiological traits. Computer monitoring is common in Israeli dairy herds, helping in the assessment of parlour...

Dairy cattle with enhanced immune responses not only have lower incidents of disease, but may also produce more bioactive compounds in their colostrum that are critical to newborn calves and are beneficial in fighting mastitis-causing pathogens, an Ontario Veterinary College (OVC) graduate student has found.
Research has shown that High Immune Responder (HIR) cows have a lower incidence of diseases, such as mastitis, metritis,...

1. Introduction Mastitis, generally defined as the inflammation of the mammary gland, is a costly and complex disease associated with variable origin, severity and outcome depending on the environment, pathogen and host (De Vliegher et al., 2012; Schukken et al., 2011). Mastitis is caused when pathogenic bacteria enter the sterile environment of the mammary gland, often as a result of disruption of physical barriers such...

Raising animals started many ages ago, and was aimed, as today, the benefit of man from the right care for domesticated animals. so; as production began, the health problems has also started, difficult problems, since in the past there wasn’t the large battery of antibiotics and antiseptics which have today. And many of these health problems still afflict producers today. One of these problems, to mention some of the most important might be the...

Introduction In theU.S., dairy products made with milk of small ruminants are considered to be specialty foods that are generally purchased by consumers who have little exposure to the realities of modern agriculture. Consumers assume that they are purchasing high quality, safe dairy products produced by healthy animals and harvested under hygienic conditions. Mastitis is an important disease of dairy animals...

Introduction The profitable production of high quality milk from healthy adult cows is the ultimate goal of most heifer management programs. The successful calving of a healthy heifer is the result of investments in effective animal health management over the 2 year period beginning at birth and culminating in the first calving. Deficiencies in health management during this period can result in the occurrence...

Introduction The quality of milk is defined based on the somatic cell count (SCC) and bacterial count of bulk tank milk. Since 1986, the dairy industry has successfully adapted to gradual reductions in allowable regulatory limits for SCC and bacteria. The dairy industry has responded by adopting methods to control contagious mastitis and the prevalence of mastitis caused by Staphylococcus aureus and Streptococcus agalactia has steadily declined...

Introduction Bovine Mastitis is economically the most significant disease of dairy cows and continues to be a persistent problem in the dairy industry at global level. With remarkably rising impact on Indian economy overall losses due to mastitis is estimated to be Rs. 7165.51 crores (Bansal and Gupta, 2009), a number which increased from 6053.2 crores in less than a decade before (Dua, 2001). As far the etiology is...

Introduction Mastitis continues to be the most frequent and costly disease of dairy cattle. Financial losses due to mastitis occur for both subclinical and clinical stages of the disease. Losses caused by subclinical mastitis are well documented. Each doubling of SCC above 50,000 cells/ml results in a loss of 0.4 kg and 0.6 kg of milk per day in first lactation and older cows, respectively (Hortet and Seegers, 1998). Losses caused by clinical...

Mastitis continues a major economic issue for dairy farmers, due to improved breeding, the cow's udder become very sensitive to infection due to its increase size, position of udder and rapid removal of large volume of milk. The heavy and big size of udder is again prone to injury and infection.
Mastitis is recognized as one of the most costly disease affecting dairy industry. It was estimated that mastitis reduces milk by 21% and butter fat by 25% (blood DC etal ) it was...

Introduction
Looking for one change in a cow's udder health status may not give you enough of a warning that something is wrong. You might miss the opportunity to treat a mastitis infection early to avoid further losses. By analyzing a combination of factors, you may be able to determine the severity of mastitis in your herd, which could help improve udder health, milk quality and your bottom line.
Clinical...

Proper dairy herd management should be designed to optimize the production of high quality milk, while minimizing any adverse effects on the health and welfare of dairy cattle. Two key ingredients in accomplishing these goals are adequate nutrition programs and sound mastitis control programs. Although historically these management areas may have been considered as separate entities, mounting evidence accumulated over the past 15 years has demonstrated a dramatic impact of proper...

One of the most common ways for dairy producers to increase milk production is by increasing milking frequency. Frequent milking during early lactation may not only increase milk yield during the frequent milking period, but also produce carry-over effects that last well into lactation. Furthermore, to produce increases in subsequent milk yield, the duration of the intervals between milking do not have to be the same, and frequent milking may only have to occur during the first 3 weeks after...
