The Montana Tropical® Composite is a recently developed beef cattle population that rapidly expanding in Brazil and other tropical countries. This mainly due to its improved meat quality adaptation climate conditions compared Zebu Taurine breeds, respectively. study aimed investigate the genetic architecture of ultrasound-based carcass traits cattle. Therefore, we estimated variance components parameters performed genome-wide association studies using weighted single-step Genomic Best Linear...
In order to determine whether selection for traits included in the index used a breeding program would increase mature weight (MW) of females, this study analyzed association between MW and four composing index: weaning (WW), post-weaning gain 345 days (PWG), scrotal circumference (SC), muscling score (MUSC). Additionally, genetic relationship with probability pregnancy at 14 months (PP14) was evaluate sexual precocity. The database 480,000 Nellore animals from Agropecuária CFM born 1984...
The ECA23:22999655C>A DMRT3 variant has been described as a causative region for the four-beat gait in horses, however it remains uncertain two distinct types observed Brazilian Mangalarga Marchador (MM) breed. This study aimed to perform single-step GWAS, prospecting genetic architecture of marcha batida (MB) and picada (MP) MM horses. Phenotypic records from 1,230 animals pedigree file containing 3172 individuals were considered current analysis. A total 192 (86 MB 106 MP) horses genotyped...
The DMRT3 gene has been described as the main influencing gait in horses; however, most studies have examined its effects by comparing information from trotted and gaited individuals.Within Brazilian Mangalarga Marchador breed, animals can present two types of gaits (marcha batida marcha picada), which differ movement form -diagonal batida) or lateral picada).We a possible association g.22999655C>A SNP with type gait, this two-gaits breed.The relationship between individuals was calculated...
Mangalarga Marchador (MM) is a very important Brazilian gaited horse breed. These animals show two gait types, differing in proportion of lateral or diagonal movements. Thus, it possible to consider the type as binary categorical trait our statistical models. Threshold models (TM) are strongly recommended handle traits for genetic evaluation purposes. However, TM susceptible extreme problem (ECP). ECP usually observed due absence variation within subclasses given systematic effect and can be...
Various studies have been conducted to improve feed efficiency in Nellore beef cattle, as well select for more sexually precocious animals.In order understand how reproduction is affected by selection efficiency, we analyzed a database containing phenotypic information from 194,063 animals, pedigree file 331,752 and genotyping of 7,631 animals.The evaluated traits were probability pregnancy at 14 months (PP14), stayability (STAY), cumulative annual productivity (COWPROD), residual intake...
A mata ciliar do Submédio São Francisco possui grande fitodiversidade com atividade biológica potencial e relação intrínseca a população ribeirinha. Com isso, o objetivo desta pesquisa foi identificar espécies conhecidas utilizadas como medicinais atestadas pela tradicionalidade uso. Os sujeitos da foram os moradores comunidade de Jatubarana localizada 600 metros das margens Rio Franciscono município Chorrochó, Bahia. coleta dados ocorreu por campo, aplicando lista livre questionário...
