Book Synopsis Principles of Animal Biometeorology by : Roberto Gomes da Silva
Download or read book Principles of Animal Biometeorology written by Roberto Gomes da Silva and published by Springer Science & Business Media. This book was released on 2012-11-13 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book begins by describing in detail the mechanisms of energy exchange – radiative, convective, conductive and evaporative – together with techniques for their determination. The discussion extends to the importance of CO2, ozone and methane, together with that of aerosol pollutants and the evolution of atmospheric CO2. Subsequent chapters apply the results of the biophysical methods to mammals, birds and aquatic animals. Discussion includes problems of shelter and shade for animals in tropical environments and techniques for the thermal evaluation for shelters and for several tree types. The details of heat exchange between animals and the environment are presented, in separate chapters covering Mammals and Birds and Aquatic Mammals. A chapter on Shade and Shelter describes the importance of shade for animals, factors of shade efficiency, the protections offered by shelter and methods of calculating the protection afforded by both shade and shelter. A Special Methods chapter offers a variety of techniques for evaluating cutaneous and respiratory evaporation, and practical methods for sampling of hairs and the evaluation of hair coat characteristics.

Book Synopsis Genetic Parameter Estimates and Breed Effects for Calving Difficulty and Birth Weight in a Multi-breed Population by : Cashley Marie Ahlberg
Download or read book Genetic Parameter Estimates and Breed Effects for Calving Difficulty and Birth Weight in a Multi-breed Population written by Cashley Marie Ahlberg and published by . This book was released on 2014 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: There are multiple breeds of beef cattle available to utilize in breeding systems to maximize production and economics. Calving difficulty (dystocia) is a significant cost to beef production and is more prevalent in first-calf heifers. The objectives of this study were to estimate genetic parameters and breed differences for calving difficulty and birth weight as a first step towards the development of across-breed adjustment factors for calving difficulty. Two models were employed to analyze birth weight (BWT) and calving difficulty (CD) recorded on 4,579 first parity females from the Germplasm Evaluation program at the U.S. Meat Animal Research Center (USMARC). Both bivariate animal models fit CD and BWT either using CD scores based on USMARC scoring system (Model 1) or CD assigned as Z scores based on the midpoint incidence rate (Model 2). Heritability estimates (SE) for BWT direct, CD direct, BWT maternal and CD maternal for model 1 were 0.35 (0.10), 0.29 (0.10), 0.15 (0.08), and 0.14 (0.08), respectively. Heritability estimates for BWT direct, CD direct, and BWT maternal for model 2 were similar to model 1. The estimate of CD maternal from model 2 was 0.13 (0.08). Genetic correlation estimates were positive between BWT direct and CD direct (0.63 ±0.17; model 1) and (0.64±0.17; model 2). All other genetic correlations were not significant. Bos Indicus influenced breeds tended to have the largest estimates of BWT direct. Calving difficulty direct breed effects ranged from -1.01 to 7.50 for model 1 and from -1.06 to 7.36 for model 2. Calving difficulty maternal breed effects ranged from -1.55 to 5.27 for model 1 and from -1.55 to 5.25 for model 2. Diverse biological types of cattle have different effects on both birth weight and calving difficulty. These differences can be used to match breeds to complement needs of production systems. Across-breed adjustment factors are needed for producers to accurately make selection decisions between sires of different breeds to improve calving difficulty.
