Book Description
Book "Milk Production - Advanced Genetic Traits, Cellular Mechanism, Animal Nutrition and Management" is made for the publication of continuation of advances in the knowledge involving milk production. This book is divided into two main sections and is devoted to more specific consideration of areas with aspects of genetics factors and the molecular and cellular mechanisms, animal management, nutrition and husbandry. This book will be useful for students, researchers, teaching staff, practicing professionals connected with dairy science, animal science, food science, nutrition, physiology, biochemistry, veterinary medicine and other related fields. Each chapter in this book has an extensive bibliography which can future aid the reader in keeping abreast of the developments in this field.

Book Description
This book is the most comprehensive introductory text on the chemistry and biochemistry of milk. It provides a comprehensive description of the principal constituents of milk (water, lipids, proteins, lactose, salts, vitamins, indigenous enzymes) and of the chemical aspects of cheese and fermented milks and of various dairy processing operations. It also covers heat-induced changes in milk, the use of exogenous enzymes in dairy processing, principal physical properties of milk, bioactive compounds in milk and comparison of milk of different species. This book is designed to meet the needs of senior students and dairy scientists in general.

Book Description
Bovine milk production and composition traits are complex quantitative phenotypes, reflecting the interplay of many environmental and genetic factors influencing mammary and lactation biology. Despite a largely quantitative architecture, genetic mapping studies have identified a handful of major effect loci in dairy cattle, each containing a large number of trait-associated sequence variants. Identifying the specific variant causally responsible at these genetic signals requires extensive experimental follow-up, where many of the genomic regions implicate present no obvious candidate mutations. The association signal is instead represented by many non-coding variants that are difficult to functionally prioritise. The aim of the research described in this thesis was to investigate four such loci segregating in NZ dairy cattle, aiming to mechanistically link causative genes and variants to the milk production and composition effects. The results of this thesis describe the identification of expression quantitative trait loci at each of the four major associated regions, providing evidence that the variants responsible exert their phenotypic influence through the modulation of mammary gene expression. Further genetic and functional experiments were conducted to elucidate the mechanism by which the implicated variants impact gene expression. Highlights of this work include the demonstration of a new mechanism of effect for the largest and most highly cited causal mutation in the bovine literature. This work also reports the discovery of major milk production effects for a mutation previously only implicated in bovine growth and stature. This thesis also reports the development and optimisation of CRISPR-Cas9 mediated genome editing as a method for testing the function of regulatory variants directly. By presenting an efficient in vitro engineering approach in mammary cells, the work creates a framework to genetically isolate candidate variants, creating opportunities to study the major effect variants reported in this thesis, and investigate other as yet undefined milk composition loci. Taken together, the work presented in this thesis provides enhanced understanding of the mechanisms linking major effect genetic variants to bovine milk production and composition, and raises the profile of these and other variants as markers to incorporate in animal selection and breeding strategies.
