Background Water is the most important nutrient for calves and plays an important role as solvent of nutrients, rumen development, thermoregulation and other functions in the body. In addition other researchers found that calves started feed consumption earlier and consumed more when unlimited access to clean drinking water is available. Generally, water comprises 70 to 75% of the weight of the calf, and they require greater...

Escherichia coli bacteria are a major cause of clinical coliform mastitis in dairy cattle. Uncontrolled bacterial replication caused by dysfunctional immune responses results in severe mammary tissue damage and death. Excessive production of reactive metabolites (RM) by phagocytic cells results in oxidative mammary tissue damage observed during coliform mastitis. Increased metabolism of polyunsaturated fatty acids (PUFA) such as arachidonic acid (AA) generates...

1. Introduction Endoparasitic nematodiasis are considered as one of the main factors seriously affecting the livestock industry, since they cause an important reduction not only in the animal weight but also their main products; that is, meat and milk are also diminished [1]. Other problems derived from nematode parasitic infections are the continuous expenses in chemical treatments and eventually the death of young...

The Dairy Focus Team at the University of Illinois at Urbana-Champaign has developed the Dairy Focus Somatic Cell Count Calculator, which allows producers to analyze their test day milk numbers and take appropriate action regarding somatic cell count. The main goal of the Dairy Focus Somatic Cell Count Calculator is to assist dairy producers in making management decisions on an individual herd level, which will improve overall health and decrease economic losses due to mastitis. Making these...

How heifers are managed at first breeding (1st breeding) represents a significant economic opportunity on many dairies. DairyComp305 records from four free-stall Holstein dairies in the Central Valley of California show how first breeding selection criteria impact first lactation (1st lactation) and subsequent reproductive performance. Our California Dairies 1, 2, 3, and 4 illustrate how...

Introduction Preventing the spread of PRRS virus (PRRSv) between groups of pigs is a major goal of pork producers. Many hog operations utilize liquid disinfectant boot baths as a part of biosecurity protocols aimed at minimizing the spread of PRRSv. Several problems arise from the current use of liquid disinfectant boot baths including their effectiveness following contamination with fecal matter and in freezing...

US -The state of California has passed a law restricting the use of antibiotics in livestock production – outlawing their use as growth promoters and feed efficiency enhancers.
The new law, which was introduced in December 2014, was passed by both the Californian Senate and Assembly last month.
It is now awaiting the final signature of the state governor Jerry Brown...

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...

Cattle constitute one of the major livestock species and an important economical factor in many countries. The world cattle population is estimated at 1.5 billion animals, more than 1 billion of them in tropical and subtropical countries. There, they are heavily exposed to numerous internal and external parasites, which drastically affect their well being as well as their productivity. Infectious diseases also play an important economical role in cattle. This paper discusses important...

Ample bedding in stalls can optimize cow comfort, reduce hock lesions and lameness, and increase cow longevity (Tucker and Weary, 2004). The great price increase seen in other more traditional bedding sources has resulted in recycled manure solids (RMS) becoming increasingly common on dairy farms. Recycled manure solids are obtained by mechanical separation of manure removed from dairy cows’ housing systems. Their low cost of recovery,...

INTRODUCTION Post partum fertility has a profound im-pact on the economic viability of dairy industry. Post-partum period is the most crucial transitory phase in bovine life when various physiological, gynaecologi-cal, biochemical and immunological changes are occurring. During this phase, cattle are exposed to increased risk of infection of uterus, as during parturition the anatomical barriers are broached and remain open for several days (Goff...
