Data from five protein-coding loci related to dairy production were used to study the genetic diversity and population structure of Argentine and Bolivian Creole cattle breeds. Genomic DNA was extracted from blood samples of six Creole cattle breeds: Argentine (n = 230), Patagonian (n = 25); “Saavedreño” (n = 140), “Chaqueño Boliviano” (n = 30), “Yacumeño” (n = 27), and “Chusco” (n = 11). κ-cas...
inherent differences observed in ionic composition of gastrointestinal contents due to diet, feeding regimen and (or) site along the length of the digestive tract were controlled so that a clearer understanding of species differences could be obtained. Three species of ruminants (i.e., Zebu cattle, sheep and goat), a pseudo-ruminant (camel) and a nonruminant (donkey) were compared. Specific dif...
Cattle are one of the most important livestock species in West Africa, providing multiple services to farmers and contributing national economies. Various breeding strategies have been implemented enhance their productivity improved farmer livelihoods. This review describes cattle experiences across spanning N’Dama breed Mali, Senegal, The Gambia breeds Azawak Zebu, Fulani taurine Baoulé Burkin...
The fertility of zebu cattle (Bos indicus) is higher than that of the European purebred (Bos taurus) and crossbred (Bos taurus × Bos indicus) cattle in tropical areas. To identify proteins related to the higher thermo-tolerance and fertility of Zebu cattle, this study was undertaken to identify differences in sperm proteome between the high fertile Malaysian indigenous zebu cattle (Kedah Kelant...
The present study was aimed to screen genetic variation within a SNP (rs136500299) located at exon 14 region of bovine ITGB6 gene among different Zebu cattle breeds. The genotyping method describe in the present study is a tetraplex ARMS PCR, which offers extremely fast, economical, and simple detection tool. The distribution of the ITGB6 genotypes among the different breeds studied suggested t...
Bovine tuberculosis is a major economic problem and a potential public health risk. Improved diagnostics like the gamma interferon (IFN-gamma) test with ESAT6 and/or CFP10 could contribute to the control program. We assessed IFN-gamma responses in zebu (Ethiopian Arsi breed) and Holstein cattle kept indoors or in a pasture to tuberculin purified protein derivative (PPD) and an ESAT6-CFP10 prote...
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...
Characterization of mitochondrial genotypes in the foundation herd of the Canchim beef cattle breed.
The Canchim (5/8 Charolais + 3/8 Zebu) beef cattle breed was developed at Southeast-Embrapa Cattle to take advantage of hybrid vigor and to combine the higher growth rate and beef quality of Charolais with tropical adaptations of Zebu. The development of three lineages (old, new, and crossbred) has increased its genetic basis. The genotypic origin (Bos taurus or Bos indicus) of the mitochondria...
By using biological data and historical research, we have tried to explain the difference between resistance and susceptibility to the diseases transmitted (cowdriosis) or associated (dermatophilosis) with the tick Amblyomma variegatum, in two cattle breeds of the French West Indies: the Creole crossbred cattle of Guadeloupe and the Brahman zebu cattle of Martinique. Have been studied the polym...
Bovine tuberculosis in domestic livestock such as cattle is an economically important disease with zoonotic potential, particularly in countries with emerging economies. We discuss the findings of recent epidemiological and immunological studies conducted in Ethiopia on host susceptibility differences between native zebu and the exotic Holstein-Friesian cattle that are increasingly part of the ...
