Characterization of bovine MHC DRB3 diversity in global cattle breeds, with a focus on cattle in Myanmar
(BioMed Central, 2020-09)
Background: Myanmar cattle populations predominantly consist of native cattle breeds (Pyer Sein and Shwe), characterized by their geographical location and coat color, and the Holstein-Friesian crossbreed, which is highly ...
Descriptive study of Rhabditis freitasi nematodes taken from Gir cattle with severe otitis in northern Brazil
(2013)
Otitis induced by rhabditiform nematodes in Gir and Indubrasilhas cattle has been reported in several states of Brazil. Nematodes eggs, larvae and adults of both sexes rhabditis freitasi were taken from infested Gir cattle ...
Parasitic otitis caused by Rhabditis (Rhabditis) freitasi (Nematoda: Rhabditidae) in the cattle Gir breed in the State of Acre
(2016-04-01)
The bovine parasitic otitis has been reported in several states of Brazil. It is caused by rhabditiforms nematodes, attacking cattle Gir and Indubrasil breeds. The aim of this work was to describe the occurrence of the ...
Análise da comercialização de bezerros de corte no sudoeste do Paraná
(Universidade Tecnológica Federal do ParanáDois VizinhosBrasilZootecniaUTFPR, 2012-10-19)
The objective of this work was to evaluate the choices of calf buyers in auctions at Southwest region of Paraná State, as well as the price variation obtained for those animals. Thus, auctions from five municipalities were ...
RAPID COMMUNICATION: Multi-breed validation study unraveled genomic regions associated with puberty traits segregating across tropically adapted breeds
(2019-07-02)
An efficient strategy to improve QTL detection power is performing across-breed validation studies. Variants segregating across breeds are expected to be in high linkage disequilibrium (LD) with causal mutations affecting ...
Genomic predictions for crossbred dairy cattle
(2020-02-01)
Genomic evaluations are useful for crossbred as well as purebred populations when selection is applied to commercial herds. Dairy farmers had already spent more than $1 million to genotype over 32,000 crossbred animals ...
Synaptomenal complex analysis of four breeds of Bos taurus taurus x B. taurus indicus hybrids
(Hereditas-distribution, 2000-12-01)
The synaptonemal complex (SC) was analyzed in four F1 hybrids of Bos taurus taurus and B. taurus indicus including Gyr-Simmental (G-S), Nelore Simmental (N-S), Gyr-Holstein-Friesian (G-H) and Nelore-Piemontese (N-P). We ...
Effects of breed proportion and components of heterosis for semen traits in a composite cattle breed
(2018-02-01)
The aim of this study was to estimate the non-additive genetic effects of the dominance component of heterosis as well as epistatic loss on semen traits in admixed Swiss Fleckvieh, a composite of Simmental (SI) and Red ...
Analysis of a polymorphism in the DGAT1 gene in 14 cattle breeds through PCR-SSCP methods
(Elsevier, 2006-06)
The diacylglycerol O-acyltransferase (DGAT1) is a microsomal enzyme that catalyzes the final step of triglyceride synthesis. Recent work have evidenced a significant association between lysine at amino acid position 232 ...
