Download or read book Embryonic Mortality in Farm Animals written by J.M. Sreenan and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reproductive wastage is a major inefficiency in all livestock production with embryonic mortality accounting for a major portion of this loss. Accordingly the Commission of the European Communities encouraged the organisation of a seminar on embryonic mortality in farm animals which was held in Brussels on the 11th and 12th of December 1984. This book contains the text of the papers, discussions and final summary presented at that Seminar. As a background to the Seminar, the extent and timing of embryonic loss was described for farm animals. Particular consideration was then given to the various mechanisms and signals, both embryonic and uterine in origin, that are so far known to be involved in the establishment of pregnancy. Possible causes of embryonic death including physiological, endocrinological, genetic and immunological components were outlined and discussed. The final summary contains general conclusions from the Seminar and recommendations for future research work on this topic. J.M. Sreenan M.G.

Diskin, The Agricultural Institute, Belclare, Tuam, Galway, Ireland ABSTRACT The extent and timing of embryonic mortality in heifers, normal cows and repeat breeder cows has been reviewed.

Available in PDF, EPUB and Kindle. Book excerpt: Master's Thesis from the year 2015 in the subject Biology - Zoology, , language: English, abstract: In the present study semen samples from NRF bulls were analysed for sperm viability, acrosome integrity and ATP content. The effect of incubation at 37 °C on sperm viability, acrosome integrity and ATP content was investigated on fresh and frozen semen samples from 20 NRF. Semen was incubated at 37 °C and the sperm quality parameters were analysed at 0 hr and after 6 and 24 hrs of incubation for both fresh and frozen samples. Sperm viability and acrosome integrity was assessed with flow cytometry and ATP content with luminometer. The incubation time at 37 °C had a significant effect on all studied parameters. However, ATP content was significantly more affected than sperm viability and acrosome integrity. After 24 hrs of incubation ATP content of frozen samples decreased approximately to 0 for all tested samples, while percentage of viability and acrosome integrity decreased by 78 ± 11.9 %. Percentage of AIL sperm cells of frozen samples decreased at corresponding rate as in fresh samples. Concerning ATP content there was however, a more marked decline in frozen samples compared to fresh samples during incubation. Sperm samples from eight NRF bulls with high and low fertility were also analysed for sperm viability, acrosome integrity and ATP content at 0 hr (right after thawing), 3, 6 and 24 hrs incubation at 37 °C. The ATP content adjusted for % AIL at 0 hr was significantly correlated with fertility measured as 56 days NRR, while % AIL or ATP content analysed separately were not correlated to field fertility.

Download or read book Reproduction in Cattle written by Peter J. H. Ball and published by John Wiley & Sons. This book was released on 2008-04-15 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cattle play a fundamental role in animal agriculture throughout the world. They not only provide us with a vital food source, but they also provide us with fertilizer and fuel. Keeping reproduction levels at an optimum level is therefore essential, but this is often a complicated process, especially with modern, high yielding cows. Written in a practical and user-friendly style, this book aims to help the reader understand cattle reproduction by explaining the underlying physiology of the reproductive process and the role and importance of pharmacology and technology, and showing how management techniques can improve reproductive efficiency. This edition includes: Recent research findings on the physiology of the oestrous cycle and its control; New techniques for monitoring and manipulating reproduction, including pregnancy diagnosis and embryo transfer; Advice on identifying common infertility problems and how to prevent and treat them. Reproduction Cattle 3e is essential reading for veterinary and agricultural students, as well as veterinarians and farmers involved in cattle reproduction.

Book excerpt: Artificial insemination is used instead of natural mating for reproduction purposes and its chief priority is that the desirable characteristics of a bull or other male livestock animal can be passed on more quickly and to more progeny than if that animal is mated with females in a natural fashion. This book contains under one cover 16 chapters of concise, up-to-date information on artificial insemination in buffalos, ewes, pigs, swine, sheep, goats, pigs and dogs. Cryopreservation effect on sperm quality and fertility, new method and diagnostic test in semen analysis, management factors affecting fertility after cervical insemination, factors of non-infectious nature affecting the fertility, fatty acids effects on reproductive performance of ruminants, particularities of bovine artificial insemination, sperm preparation techniques and reproductive endocrinology diseases are described. This book will explain the advantages and disadvantages of using AI, the various methodologies used in different species, and how AI can be used to improve reproductive efficiency in farm animals.

This book was released on 2010-04-01 with total page 357 pages. Available in PDF, EPUB and Kindle. Book excerpt: This practical, extensively illustrated handbook covers the procedures that are undertaken in andrology and ART laboratories to analyse and assess male-factor infertility, and to prepare spermatozoa for use in assisted conception therapy. The content is presented as brief, authoritative overviews of the relevant biological background for each area, plus detailed, step-by-step descriptions of the relevant analytical procedures. Each technical section includes pertinent quality control considerations, as well as the optimum presentation of results. In addition to the comprehensive 'basic' semen analysis, incorporating careful analysis of sperm morphology, the handbook provides established techniques for the use of computer-aided sperm analysis and sperm functional assessment. Throughout the handbook the interpretation of laboratory results in the clinical context is highlighted, and safe laboratory practice is emphasized. It is an invaluable resource to all scientists and technicians who perform diagnostic testing for male-factor infertility.
