The Beef Cattle Institute at Kansas State University (BCI) has developed bilingual educational tools based on audiovisual technology to improve technical knowledge within livestock operations. The Dairy Animal Care and Quality Assurance (DACQA) program is available in a package of 36 multimedia modules with a total length of 2hrs and 42 min of training material to train animal care givers in ar...

A growing concern of the dairy industry is to increase dairy cattle wellbeing in anticipation of a demand from the general public of welfare-certified dairy products. Lameness is one of the most important welfare issues of high producing dairy cows in North America (Vermunt, 2007). It is a debilitating condition that challenges sustainability of production systems used in North America because ...

economic data and performance records from 10 iranian holstein dairy cattle herds, as well as milk production and fertility records from iranian center of animal breeding and animal production improvment were used to estimate the effect of calving difficulty on milk production, fertility and as well on the economic aspects of maternal and direct calving difficulty. calving difficulty could be d...

Commercial artificial insemination (AI) is arguably one of the greatest animal biotechnologies introduced in the 20 century. The benefits of improved genetics and reduced disease transmission have been readily recognized and accepted by the dairy producer, and at present, approximately 70% of the US dairy cattle population are bred by AI. Since the introduction of commercial AI in the early 194...

Bovine neosporosis caused by the apicomplexan protozoan parasite N. caninum, was initially recognized in 1989 and is now reported as a leading infectious cause of reproductive failure in dairy cattle in world wide. The aim of this study was to determine the seroprevalence of N. caninum infection in industrial dairy cattle of Hamedan province (west of Iran) by ELISA method. Blo...

Dairy cattle breeding programs have been based in the selection for traits related to milk production. In this research a data set of 63 herds of East Azerbaijan province Holstein cattle, collected during 2002-2013 by the Iranian Animal Breeding Center was used to estimate the repeatability and heritability of three traits of economic importance. Genetic parameters for first three lactations of...

Reproductive failure in inseminated cattle results from poor fertilization and embryo survival. Recent studies utilizing dairy and beef cattle indicate that fertilization rates are higher for nulliparous dairy and beef heifers and nonlactating beef cows than lactating beef and dairy cows and nonlactating dairy cows. Several factors affect fertilization rates, but the greatest impact was observe...

introduction about 500,000 species of fungi have been realized up to now. there are abundant fungi in air, soil and our environment. so the growth of them increases in the presence of air moisture and appropriate temperature. however saprophytic fungi have a wide distribution in nature, they are responsible for decomposition of organic materials and playing an important role in the biogeochemic...

This paper addresses the economic and strategic position of animal health in the dairy operations and the way that animal health care should be properly designed. Examples of biosecurity plans and quality risk management are further elaborated. Disease risk identification and disease risk management as primary preventive issues are pivotal in modern animal health care on both the small and larg...

Infectious bovine rhinotracheitis (IBR) is a highly infectious disease of cattle caused by bovine herpesvirus 1 (BHV-1) that causes considerable economic losses to the dairy and beef industry. This report describes the results of two surveys in which prevalence of serum antibodies against BHV-1 in Galicia (NW Spain) was determined. The first was performed on the entire cattle population of the ...
