This book was released on 2019 with total page 71 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objectives of this research were to 1) evaluate the effects of late gestation supplementation, synchronization and creep feeding on cow and calf production traits 2) evaluate the pooled effects of 5 studies involving late gestation supplementation on cow and calf traits. Experiment 1 was a three year study conducted on 8 pastures at the Gudmundsen Sandhills Laboratory. Cows were assigned to 1 of 4 late-gestation supplementation treatments, postpartum progestin or control, and 1 of 2 creep feed treatments to make up a 4 x 2 x 2 factorial arrangement. Calves were followed through to slaughter. Experiment 2 involved 5 studies all conducted at the UNL Gudmundsen Sandhills Laboratory. Studies were pooled based on similar treatments of late gestation supplementation on dormant upland pasture or meadow and different weaning periods. Cow and calf data was analyzed for various traits. Within Experiment 1 all three levels of supplementation increased cow BW and BCS, while the non-supplemented decreased in both. Supplementation treatments did not affect reproductive efficiency such as calving date, calving rate, weaning rate or pregnancy rate. Synchronization had similar results as there were no effects on reproductive measures or calf BW. Supplementation to cows had no effect on calf production traits through slaughter. Creep feeding calves significantly increased calf BW at weaning, yield grade and 12th rib fat. However on a cost/ benefit analysis creep feeding under these conditions added no value on profitability. Different results were achieved with the larger data set of late gestation supplementation. The pooled analysis demonstrated significant effects from supplementation on cow pregnancy rate, adjusted calf BW at weaning but no effect on carcass characteristics. March systems had a higher average pair feed cost but lower cow replacement cost compared to May. The March calving system had higher average net returns based on 9 yrs of market data compared to a May calving system. These studies indicate the effect and importance of late gestation supplementation on cow and calf productivity in a spring calving herd. Cow-calf producers should carefully consider calving system utilization based on their unique production goals.

This book was released on 2012-12-06 with total page 588 pages. Available in PDF, EPUB and Kindle. Book excerpt: This publication contains the proceedings of a seminar held in Germany (Fed. Rep.) on May 4 -6, 1977, under the auspices of the Commission of the European Communities, as part of the EEC programme of co ordination of research on beef production. The programme was drawn up by a combined scientific working group on Genetics and Selection and on Nutrition and Management on behalf of the Beef Production Committee. The working group consisted of Professor Dr. Neimann S~rensen (Denmark, Chairman), Dr. Brolund Larsen (Denmark), Mr. Boccard (France), Dr. H. de Boer (Netherlands), Priv.-Doz. Dr. B. Hoffmann (Germany, Fed. Rep.), Professor Dr. H.J. Langholz (Germany, Fed. Rep.), Dr. J.W.B. King (UK), Mr. R. Jarrige (France), Mr. B. Vissac (France), Professor Dr. A. Romita (Italy), Professor Dr. E.P. Cunningham (Ireland), Mr. P. L'Hermite (CEC) and Dr. J.C. Tayler (Scientific Adviser to CEC). The subject chosen for this seminar was drawn from the list of priorities in research objectives drawn up in 1973 by members of a committee (now the Standing Committee on Agricultural Research, (~PRA). One of the functions of this series of seminars was to summarise and update the information available on the selected subjects and to discuss future needs for research, so as to assist the Commission in evaluating the probable impact of research on agri cultural production within the Community.

Download or read book Factors Affecting Calf Crop written by Michael J. Fields and published by CRC Press. This book was released on 2021-11-18 with total page 385 pages. Available in PDF, EPUB and Kindle. Book excerpt: Factors Affecting Calf Crop summarizes the latest information available from leading cattle physiologists and geneticists regarding factors known to influence the production of live calves at weaning. You get practical information on management techniques for improving reproduction efficiency in the herd. You'll also learn about the functioning of the reproductive system and how this may affect reproductive processes in the cow herd. Managers will benefit from a clearer understanding of the factors known to limit efficient reproduction, while veterinarians and other professionals who advise cattlemen will appreciate the substantial reference material and color photographs for defining cow condition scores. Color photographs are also used to illustrate the discussions of testicular thermographies and their applications. Other chapters in the book cover developments in improving reproductive performance of the replacement heifer, the brood cow, and the bull. Topics on reproduction include physiology/endocrinology, the use of growth promotants, genetics and physiological and economic considerations in selecting the age to breed heifers, heritability of fertility, length of the breeding season, prepartum and postpartum nutrition, nursing by the calf, cloning of embryos, and much more.
