- Abstract:
- ... Nelore cattle breed was farmed worldwide due to its economic importance in the beef market and adaptation to the tropics. In Brazil, purebred Nelore animals (PO) receive a certificate from the breeders' association based on the animal's genealogy and morphological characterization. The top 20 to 30% of the superior animals are eligible to receive the Special Certificate of Identification and Produ ...

- Abstract:
- ... Sugarcane is a major crop cultivated globally for sugar and bioenergy production, with increasing relevance as a biomass source. Association mapping studies, in turn, identify markers associated with target traits that may assist genotype selection. Here, we used a diversity panel comprising 100 sugarcane genotypes to investigate the clustering patterns using phenotypic data, i.e., sugar content ( ...

- Abstract:
- ... A new goal in animal breeding programs is to improve not only trait means, but also to decrease the level of phenotypic variation. One way to achieve uniformity is through selection for reduced residual (environmental) variance, if this is a trait under genetic control. The objective of our study was to evaluate the opportunity of selection for uniformity of harvest weight (HW) and to investigate ...

- Abstract:
- ... Increasing productivity through continued animal genetic improvement is a crucial part of implementing sustainable livestock intensification programs. In Zebu cattle, the lack of sexual precocity is one of the main obstacles to improving beef production efficiency. Puberty-related traits are complex, but large-scale data sets from different “omics” have provided information on specific genes and b ...

- Abstract:
- ... The inclusion of genomic information became a reality in shrimp breeding and it is expected to accelerate the genetic gain over time. The decay of linkage disequilibrium (LD) between single nucleotide polymorphisms (SNPs) is an important measure to evaluate the feasibility of implementing genomic selection. The aim of this study was to evaluate the use of a novel 50 K SNP array tool to characteriz ...

- Abstract:

There is evidence in the literature that MS outperforms OCS in controlling inbreeding under the same expected genetic gain in the short-term. It is unclear, however, if the same would occur in the long-term. This study aimed to compare OCS and MS re ...

BACKGROUND: A cost-effective strategy to explore the complete DNA sequence in animals for genetic evaluation purposes is to sequence key ancestors of a population, followed by imputation mechanisms to infer marker genotypes that were not originally reported in a target population of animals genotyped with single nucleotide polymorphism (SNP) panels. The feasibility of this process relies on the ac ...
