The latest edition of Animal Nutrition has been updated thoroughly to provide a clear and comprehensive introduction to the science and practice of animal nutrition. This classic, market-leading text is a trusted resource for undergraduates studying Animal Science, Veterinary Science, Agriculture, Biology and Biochemistry. It is supported by key experimental evidence throughout about modern advancements in animal food nourishment, composition of foods and feeding standards for dairy and beef cattle, sheep, pigs and poultry, horses, and cats and dogs.

It is split into six main sections covering: The components of food; The digestion and metabolism of nutrients; Quantifying the nutrient content of foods: digestibility, energy and protein values; The nutrient requirements of animals; The nutritional characteristics of foods; and Animal products and human nutrition. Quantitative aspects of the subject are clearly explained and illustrated by worked examples. Problems have been added to all chapters to aid student learning and the appendices include solutions to all chapter-end numeric questions.

This edition includes nutritional topics related to molecular biology, the environment, and companion animals - dog and cat nutrition has been expanded. Under nutrient requirements of animals, usage of novel foods such as insects has also been added. Chapter-end summaries and questions allow students to recap and test their knowledge of the chapter topic.

In this multi-volume edition, the poetry of W.B. Yeats (1865–1939) is presented in full, with newly-established texts and detailed, wide-ranging commentary. Yeats began to write verse in the nineteenth century, and over time his own arrangements of poems repeatedly revised and rearranged both texts and canon. This edition of Yeats’s poetry presents all his verse, both published and unpublished, including a generous selection of textual variants from the many manuscript and printed sources. The edition also supplies the most extensive commentary on Yeats’s poetry to date, explaining specific references, and setting poems in their contexts; it also gives an account of the vast range of both literary and historical influences at work on the verse. The poems are presented in order of composition, and major revisions or rewritings of poems result in separate inclusions (in chronological sequence) for these writings as they were subsequently reconceived by the poet.

This first volume collects Yeats’s poetry of the 1880s, from his ambitious and extensive juvenilia (including hitherto little-noticed dramatic poems) to his earliest published pieces, leading to his first substantial book of verse. The pastoral romance of classically-inflected early work like ‘The Island of Statues’ is succeeded in these years by the Irish mythic material that finds its largest canvas in the mini-epic ‘The Wanderings of Oisin’. In Yeats’s work through the 1880s, an adolescent poet’s youthful absorption in Romantic poetry is replaced by a commitment to esoteric religious speculation and Irish political nationalism. This edition allows readers to see Yeats’s emergence as a poet step by step in compelling detail in relation to his literary influences – including, significantly, the Anglo-Irish poetry of the nineteenth century. The commentary provides an extensive view of Yeats’s developing personal, cultural, and historical worlds as the poems gain in maturity and depth. From the first attempts at verse of a teenage boy to the fully accomplished writings of an original poet standing on the verge of popular success with poems such as ‘The Lake Isle of Innisfree’, Yeats’s poetry is displayed here in unprecedented fullness and detail.

In this second volume, the poems of Yeats’s early maturity emerge in the contexts of his engagement with Irish history and myth, along with nationalist politics; his increasing involvement with ritual magic and esoteric lore; and his turbulent, often unhappy, personal life. The poems of The Countess Kathleen and Various Legends and Lyrics (1892) reveal a poet of intense narrative power and metaphorical resource, adept at transforming miscellaneous sources into haunting and original poems. A major revision of his earlier narrative, ‘The Wanderings of Oisin’, takes place in this decade when Yeats is also taken up with the composition of elaborate and uncanny symbolic lyrics, many of them resulting from his love for Maud Gonne, that are finally collected in The Wind Among the Reeds (1899). This edition makes it possible to trace in detail Yeats’s debts to folklore and magic, alongside his involved and often difficult private and public life, in poetry of exceptional complexity and power.

In this third volume, Yeats’s poetry of the first decade of the twentieth century is brought into sharp focus, revealing the extent of his efforts to re-fashion a style that had already made him a well-known poet. All of the major modes in Yeats’s earlier work are subject to radical re-imagining in these years, from poetic narrative founded in Irish myth, in poems such as ‘Baile and Aillinn’ and ‘The Old Age of Queen Maeve’, to the symbolist drama-poetry of The Shadowy Waters, here edited in its two (completely different) versions of 1900 and 1906. In a decade when the theatre was one of Yeats’s principal concerns, his lyric poems, which were becoming increasingly explicit in personal terms, began to discover new intensities of conversational pitch and mythic resonance. Poems such as ‘The Folly of Being Comforted’, ‘Adam’s Curse’, ‘No Second Troy’, and ‘The Fascination of What’s Difficult’ are given close attention in this new edition, alongside topical and epigrammatic pieces that are often passed over in accounts of Yeats’s development. The evolving complexities of Yeats’s personal and political lives are crucial to his artistic growth in these years, and the commentary gives these generous attention, showing how the poetry both feeds upon and often transcends the circumstances of its composition. The volume offers strong evidence for this decade as a crucial one in Yeats’s poetic life, in which the poet created wholly new registers for his verse as well as new dimensions for his imaginative vision.
