Mitochondrial control region genetic diversity and maternal ancestry of a Brangus-Ibage cattle populations

open access: yesGenetics and Molecular Biology, 2005
The genetic diversity of 277 nucleotides in the mitochondrial DNA control region (nt 15,964 to 16,240 in reference sequence) was analyzed in crossbreed beef cattle (Brangus-Ibage, 5/8 Bos primigenius taurus x 3/8 Bos primigenius indicus) as well as in ...

The genomes and history of domestic animals [PDF]

open access: yes, 2016
This paper reviews how mammalian genomes are utilized in modern genetics for the detection of genes and polymorphisms (mutations) within domesticated animal (mostly livestock) genomes that are related to traits of economic importance to humans.

Supplementation strategies for beef cattle managed in integrated systems: Impacts on animal production and grain yields

open access: yesAgronomy Journal, Volume 117, Issue 6, November/December 2025.
Abstract The use of feed supplements can enhance land yield in crop‐livestock integrated systems (CLIS). Thus, a study was conducted in Montes Claros de Goiás, Brazil, between 2020 and 2023. The system comprised soybean [Glycine max (L.) Merr.] cultivation during spring/summer (generally, sowing in November and harvesting in March), followed by Zuri ...

Observations of tear‐drinking by lepidopterans on moose (Alces americanus americanus) in northeastern North America

open access: yesEcosphere, Volume 16, Issue 11, November 2025.
Abstract Lepidoptera have long been known to feed on the tears of vertebrates as a presumed source of minerals or nutrients. While this unusual behavior has been observed in a variety of species, only a single previous record has been documented outside of the tropics. Here, we present the first documentation of moths visiting the eyes of a bull moose (

Quantitative trait locus affecting birth weight on bovine chromosome 5 in a F2 Gyr x Holstein population

open access: yesGenetics and Molecular Biology, 2005
Segregation between a genetic marker and a locus influencing a quantitative trait in a well delineated population is the basis for success in mapping quantitative trait loci (QTL). To detect bovine chromosome 5 (BTA5) birth weight QTL we genotyped 294 F2

Comparisons of \u3ci\u3eBos indicus\u3c/i\u3e and \u3ci\u3eBos taurus\u3c/i\u3e Inheritance for Carcass Beef Characteristics and Meat Palatability [PDF]

open access: yes, 1993
Crossbreeding is used widely to exploit heterosis and additive genetic variation among breeds to improve efficiency of beef production. The economic value of Bos indicus breeds of cattle, primarily Brahman, in crossbreeding programs in subtropical and ...

Detecting Convergence of Amino Acid Physicochemical Properties Underlying the Organismal Adaptive Convergent Evolution

open access: yesMolecular Ecology Resources, Volume 25, Issue 8, November 2025.
ABSTRACT Many studies have proposed various comparative genomic methods to probe the molecular basis for adaptive functional convergence between species, conventionally by detecting the convergence of amino acid states between orthologous protein sequences of these species or lineages.

Distinctive gene expression patterns and imprinting signatures revealed in reciprocal crosses between cattle sub-species

open access: yesBMC Genomics, 2021
Background There are two genetically distinct subspecies of cattle, Bos taurus taurus and Bos taurus indicus, which arose from independent domestication events.

Dietary Response of Black‐Backed Jackals (Lupulella mesomelas) to Contrasted Land Use

open access: yesEcology and Evolution, Volume 15, Issue 10, October 2025.
This study examines dietary shifts in black‐backed jackals across different land‐use types using DNA metabarcoding. Results reveal that jackal diets vary significantly by landscape and season, with a strong reliance on sheep in livestock areas, selective feeding on greater kudu on game farms, and a broader, more even prey profile in nature reserves ...
