Blood samples were collected from eight native Japanese breeds of chickens (Miyadi-dori, Ohiki, Onaga-dori, Shoukoku, Tosa-Jidori, Tosa-Kukin, Toutenkou and Uzurao) and two foreign breeds of chickens (White Leghorn and Rhode Island Red) to examine the genetic variability and relationships among the breeds by using a microsatellite DNA technique. Except for the Shoukoku breed, the other Japanese...
Autochthonous cattle breeds are a valuable reservoir of genetic diversity in Spain. Along their history, these breeds had been subjected to strong forces of differentiation and common selection. Based on genomewide SNP data from five different autochthonous breeds, in this study we computed two classical selection signatures statistics in a sliding windows scan along the genome. The statistics ...
the purpose of the given work was to study the dairy efficiency of the delivered, local and crossbreed goats in three different generations (f1, f2 and f3), derived from their crosses, as well as the biochemical composition of milk and some bloodplasma hormones, participating in the process of lactopoez. for the biochemical tests of milk we have selected casein and serumproteins, iron in lactof...
Till date the available data regarding goat breeds suggests that out of 570 breeds; 187 (33%) are found in Europe, 146 (26%) Asia and Pacific region 89 (16%) Africa [1]. All these totally comprise 422 breeds. But exact for remaining 48 under controversy. Speculatively they either wild or on verge extinction having only a few numbers individuals [2].
Domestic dogs share a wide range of important disease conditions with humans, including cancers, diabetes and epilepsy. Many of these conditions have similar or identical underlying pathologies to their human counterparts and thus dogs represent physiologically relevant natural models of human disorders. Comparative genomic approaches whereby disease genes can be identified in dog diseases and ...
Despite the long history of purebred dogs and the large number of existing breeds, few studies of canine litter size based upon a large number of breeds exist. Previous studies are either old or include only one or a few selected breeds. The aim of this large-scale retrospective study was to estimate the mean litter size in a large population of purebred dogs and to describe some factors that m...
Tsigai and Improved Valachian are the most spread sheep breeds in Slovakia. Both are multi-purpose breeds (Krupová et al., 2009), well adapted to local climate and environment. Tsigai is one of the oldest native breeds in areas from 500 to 800 m above sea level, mostly in the semi-extensive production system (Krupová et al., 2009), while improved Valachian is mostly kept in mountains and foothi...
BACKGROUND American Creole cattle presumably descend from animals imported from the Iberian Peninsula during the period of colonization and settlement, through different migration routes, and may have also suffered the influence of cattle directly imported from Africa. The introduction of European cattle, which began in the 18th century, and later of Zebu from India, has threatened the survival...
In this study, we performed a population viability analysis on 3 domestic horse breeds (Equus caballus) of Danish origin, namely, the Frederiksborg, the Knabstrupper, and the Jutland breeds. Because of their small population sizes, these breeds are considered endangered. The Vortex software simulation package was used for the population viability analysis. First, we investigated the future viab...
Objective: An increased risk of mast cell tumours (MCT) in certain breeds has been described repeatedly in the literature. The incidence of MCTs for registered breeds in Austria, an estimate of the risk by means of the odds ratios based on breed as well as the anatomic localisation of MCTs were examined. Material and methods: In the first part of the study, the ranking of breeds in Austria base...
