Equine Color Genetics, Fourth Edition presents a detailed examination of the color variation in horses and donkeys and the genetic mechanisms that produce color variations. * Thoroughly covers the ...basic colors in horses, including bay, chestnut, black, and brown * Details the genetic basis of the colors built from the basic coat color, including dilutions and white patterning * Provides an explanation of genetic mechanisms that determine coat color * Presents a thorough revision and update, including new advances in molecular genetics, biochemistry, molecular mechanisms, genetic loci, coat colors before domestication, and more * Offers a new introduction describing the principles of genetics and genomics research to help outline how knowledge is discovered and to assist the reader in understanding concepts covered in the book
Artificial weaning is a standard practice known to be one of the most stressful events in a domestic foal's life. Research has mainly focused on ways to alleviate weaning stress. However, there is ...still a need for more detailed research on what should constitute best practices with respect to animal welfare. The aim of this review is to address this issue by examining the natural weaning process. We first provide an overview of the scientific literature on the natural temporal dynamics of the dam-offspring bond in horses: it is to be noted that the natural process of weaning is little documented, individual variations have been poorly investigated and immediate effects of weaning on the mare-foal relationship remain unexplored. To partly address these gaps, we performed a study around the weaning period on 16 mare-foal pairs kept with minimal human interference. Most foals were weaned spontaneously when 9-10 months old, with individual variations mainly due to the conception rate of mares. Natural weaning induced no stress response in either partner and was performed without clear signs of rejection by the dams either just before or after. We lastly open up the discussion on the need for rethinking weaning practices under domestic conditions.
There is a lack of reliable data in agribusiness regarding the economic efficiency of horse breeding, and this limits its further development. The purpose of this study was to create rational ...parameters for the development of productive horse breeding as an effective agricultural business, in particular, in relation to farms.
The methods of investigation used were induction and deduction, as well as analytical, statistical, and economic-mathematical analysis. We also used the dynamics of time series, CVP analysis, direct costing, and microeconomic analysis. Data were taken from the Russian Federation's official statistics on animal husbandry as well as closed (commercial) data of agricultural enterprises from our study region.
Horse ownership in the Republic of Bashkortostan is higher than in the rest of Russia with about 9% of the total number of horses in Russia. We found that landowners need one hectare of arable land to ensure profit and that the highest economic income occurs on farms specializing in kumis production. The production of kumis under intensive farming is less profitable than with free-range horses kept in pastures. Family farms need a large amount of arable land with natural foliage to balance space and profit.
Successful implementation of these parameters will make it possible to turn agriculture into successful horse breeding businesses. The expected volume of agricultural production may be approximately 9-11 thousand US dollars per employee.
In 2012, the New York Times published a series of reports addressing doping and fatal breakdowns in U.S. horse racing. This study examines the extent to which the Times transferred the salience of ...certain story attributes to news media at the regional and national levels. Reports appearing after the Times began its investigation were more likely to mention (1) an injured or deceased horse, (2) equine drug use, and (3) a trainer suspension or other disciplinary action. The study concludes that, in addition to transferring object salience, the Times also may affect how news organizations characterize issues and events.
The theory and application of mammalian genetics have been evolving rapidly over the past two decades. This has given scientists fresh insight into the biological processes which affect the functions ...of the animal in question. This is the latest title in our successful series of genetics books. Reference book providing a comprehensive review of the current research in horse geneticsChapters written by international experts in the field Of worldwide relevance
Imagine a hawk's view of the magnificent bluegrass pastures of Kentucky horse country. Circle around the remnants of a breeding farm, four beautiful horses grazing just beyond the paddock. Inside the ...ramshackle house, a family is falling apart. Hack, the patriarch breeder and trainer, is aged and blind, and his wife, Louetta, is confined by rheumatoid arthritis. Their daughter, Jewel, struggles to care for them and the horses while dealing with her own home and job—not to mention her lackluster second husband, Eddie, and Carley, her drug- addicted daughter. Many days, Jewel is only sure she loves the horses. But she holds it all together. Until her brother, Cal, shows up again. Jewel already has reason to hate Cal, and when he meets up with Carley, he throws the family into crisis—and gives Jewel reason to pick up a gun. Every family has heartbreaks, failures, a black sheep or two. And some families end in tatters. But some stumble on the secret of survival: if the leader breaks down, others step up and step in. In this lyrical novel, when the inept, the addict, and the ex-con join to weave the family story back together, either the barn will burn to the ground or something bigger than any of them will emerge, shining with hope. Remember My Beauties grows large and wide as it reveals what may save us. For more information, visit lynnehugo.com
The aim of this study was to estimate microbiological quality of bioaerosols sampled from indoor and outdoor air of stables. Two types of closed stables (type 1 and 2) and one opened were tested ...during winter, spring and summer periods. Summary the highest number of bacteria was in closed stable type 2 (above 105 CFU×m-3), then opened (up to 105 CFU×m-3) and stable type 1 (near low 104 CFU×m-3). The number of fungi did not exceed 104 CFU×m-3 and was the greatest in stable type 1. Pool of mesophilic bacteria isolated from bioaerosols of both closed stables represented almost the same genetic profile, as well as between psychrophilic bacteria isolated from opened stable and background.
