Abstract (sommario):

Genetic variation at 20 microsatellite loci was surveyed to determine the evolutionary relationships and molecular biogeography of 20 different cattle populations from Africa, Europe and Asia. Phylogenetic reconstruction and multivariate analysis highlighted a marked distinction between humpless (taurine) and humped (zebu) cattle, providing strong support for a separate origin for domesticated zebu cattle. A molecular clock calculation using bison (Bison sp.) as an outgroup gave an estimated divergence time between the two subspecies of 610,000-850,000 years. Substantial differences in the dis

Abstract (sommario):

Digital dermatitis or Mortellaro’s disease is a highly prevalent bovine dermatological disorder situated in the foot region that causes lameness and impairs animal welfare. In this first part of a twin paper, the role of genetics, immunity, bacteria and hygiene in the development of this complex disease are described. There is still no consensus regarding the role of the immune system and the typically isolated Treponema spp. in the pathogenesis of digital dermatitis. Moisture and dirt are undoubtedly important for disease transmission in and between dairy farms; furthermore, the genetic compo

Abstract Various cattle populations in the Americas (known as criollo breeds) have an origin in some of the first livestock introduced to the continent early in the colonial period (16th and 17th centuries). These cattle constitute a potentially important genetic reserve as they are well adapted to local environments and show considerable variation in phenotype. To examine the genetic ancestry and diversity of Colombian criollo we obtained mitochondrial DNA control region sequence information for 110 individuals from seven breeds.

Abstract (sommario):

Bovine spongiform encephalopathy (BSE) is a prion disease that is invariably fatal in cattle and has been implicated as a significant human health risk. As a transmissible disease of livestock, it has impacted food safety, production practices, global trade, and profitability. Genetic polymorphisms that alter the prion protein in humans and sheep are associated with transmissible spongiform encephalopathy susceptibility or resistance. In contrast, there is no strong evidence that nonsynonymous mutations in the bovine prion gene (PRNP) are associated with classical BSE (C-BSE) disease susceptib

Abstract (sommario):

Genotype data from 21 microsatellites were used to evaluate genetic diversity and relationships of Gatacko cattle and Busha breeds. A total of 100 animals included in the study were divided into three groups: Gatacko cattle (GC), Busha from eastern Herzegovina (BEH) and Busha from western Herzegovina (BWH). Hardy-Weinberg equilibrium was observed for all loci in all groups, except for single locus (INRA35) in group of Busha from western Herzegovina. A total number of 166 alleles were detected in a total sample. The average number of alleles per locus was 7.9. The highest observed mean heterozy

Abstract (sommario):

Fatty acid composition and conjugated linoleic acid (CLA) content in pars costalis diaphragmatis (PCD) muscle from European and British crossbred (EBC; no Wagyu genetics) and Wagyu crossbred (WC; 75% Wagyu genetics) beef cattle were determined. Conjugated linoleic acid contents of PCD muscle from EBC (1.7 mg CLA g−1 lipid) and WC (1.8 mg CLA g−1 lipid) cattle were similar (P > 0.05), while WC cattle had higher (P < 0.05) CLA content 100 g−1 of beef on a DM basis because the lipid content of meat from WC cattle was greater (P < 0.05) than that from EBC cattle Key words: Conjugated lino

Abstract (sommario):

A comprehensive review of the impact of tropical pasture grazing, nutritional supplementation during feedlot finishing and fat metabolism-related genes on beef cattle performance and meat-eating traits is presented. Grazing beef cattle on low quality tropical forages with less than 5.6% crude protein, 10% soluble starches and 55% digestibility experience liveweight loss. However, backgrounding beef cattle on high quality leguminous forages and feedlot finishing on high-energy diets increase meat flavour, tenderness and juiciness due to improved intramuscular fat deposition and enhanced mono- a

Abstract (sommario):

Background. In Ethiopia, livestock contributes 45% of agricultural GDP. Despite the economic role played by the sector, there have been little efforts to genetically improve the indigenous cattle. Morphological characterization of selected Ethiopian indigenous cattle has been made for (Bonga, Jimma, and Kerayu) cattle types. But, the selected indigenous cattle were not characterized at molecular level (genetic diversity information). Hence, this work was initiated to detect and determine the genetic diversity and population structure of selected Ethiopian indigenous cattle ecotypes using micro

Abstract (sommario):

Plasma leptin concentrations and beef cattle carcass characteristics in eight Continental Crossbred steers [0% Wagyu Cattle (WC)] were compared to crossbred cattle with 50 and 75% WC (eight steers each) genetic makeup to determine if a relationship exists between plasma leptin concentrations and intramuscular fat content (marbling) in beef cattle. Plasma leptin concentrations were measured at two stages of cattle growth, 16 and 4 wk prior to slaughter (W P S). Beef cattle characteristics including marbling score, ribeye area, i.m. total lipid content, and backfat depth were determined, and cor

Abstract (sommario):

In vitro embryo production (IVEP) is used to develop high-quality genetics associated with intergenerational genetic gain. It is characterized by acquisition (in vivo or post-mortem) and maturation (MIV) of oocytes from donors, followed by fertilization (FIV) of matured oocytes and culture (IVC) of embryos, which are then sent to transferred or cryopreserved. Even with extensive knowledge on IVEP, some biochemical and hormonal regulations that involve embryonic development are still unknown, leading to a low overall efficiency of the biotechnological process. Although in vitro developed embryo

Abstract (sommario):

Bilateral convergent strabismus with exophthalmos (BCSE) is a malformation of the eyes and is recognized as a mild but progressive disorder that affects cattle in the first two years of life. This most likely inherited disorder is rarely described in cattle resembling autosomal dominantly inherited forms of human progressive external ophthalmoplegia (PEO). In German Braunvieh cattle, two linked genome regions were found that could be responsible for the development and/or progression of BCSE. The goal of this study was to phenotypically characterize BCSE in Holstein cattle from Germany and Swi
