Dairy cattle include replacement heifer calves and yearlings, dry cows, lactating cows, and breeding bulls used for research and teaching purposes related to milk production. The basic requirements for safeguarding the welfare of dairy cattle are an appropriate husbandry system that meets all essential needs of the animals. Dairy farming is a class of agriculture for long-term production of milk, which is processed for eventual sale of a dairy product. The text Dairy Cattle and Milk Production focuses on physical techniques for increasing milk production. The objective of first chapter is to explore the biological role of the FTO locus as a functional candidate on milk composition, in particular fat yield. Second chapter discusses on the GWA analysis for milk production traits in dairy sheep and genetic support for a QTN influencing milk protein percentage in the Lalba gene. Cattle management for dairying in Scandinavia’s earliest Neolithic has been discussed in third chapter. The objective of fourth chapter is to examine differences in the milk proteome and other important milk components in the colostrum and mature milk from three transgenic cloned cattle lines. Vaccination of lactating dairy cows for the prevention of aflatoxin B1 carry over in milk has been focused in fifth chapter. In sixth chapter, we discuss on improvement of prediction ability for genomic selection of dairy cattle by including dominance effects. A case study in dairy cattle has been introduced in seventh chapter. Eighth chapter deals with high prevalence of bovine tuberculosis in dairy cattle in central Ethiopia. A multiple-SNP approach for genome-wide association study of milk production traits has been discussed in ninth chapter. Prediction and control of brucellosis transmissions of dairy cattle have been revealed in tenth chapter. The application of selection mapping to identify genomic regions associated with dairy production in sheep has been presented in eleventh chapter. The objective of twelfth chapter is to investigate whether the maternal environment influences the subsequent postnatal milking performance of the resulting daughter and grand-daughters under New Zealand conditions. The aim of thirteenth chapter is to study the AFB1-specific Ab response in Holstein Freisian heifers immunized systemically with AnAFB1 conjugated with KLH and CRM197 carrier proteins. The effect of closantel treatment on milk production has been discussed in fourteenth chapter. The impact of bacterial and somatic cells content on quality fresh milk in small-scale dairy farms has been measured in fifteenth chapter. The objective of sixteenth chapter is to identify regions of the genome associated with milk production traits and somatic cell score in cattle fed a basal diet of grazed grass using single nucleotide polymorphisms regression.In seventeenth chapter, we assess the current occurrence of heat-stress days for dairy cattle and assess the impacts on milk yields.The objective of eighteenth chapter is to determine the effect on milk production in cows and heifers.A review on risk factors and potential sources of digital dermatitis in dairy cows has been discussed in nineteenth chapter.Last chapter examines the magnitude and direction of sex-biased milk synthesis in the Holstein breed of Bos Taurus.
