Genetic characterization of Indubrasil cattle breed population. Repositório Alice
ZANELLA, R.; LAGO, L. V.; SILVA, A. N. da; PÉRTILLE, F.; CARVALHO, N. S. de; PANETTO, J. C. do C.; ZANELLA, G. C.; FACIOLI, F. L.; SILVA, M. V. G. B..
Abstract The Indubrasil breed was developed in the Brazilian region called Triângulo Mineiro as a result of a cross between zebu cattle. Initially, it was used as a terminal cross and currently it represents approximately 4.45% of all the Brazilian zebu cattle. Studies were conducted to estimate genetic parameters in the Indubrasil using pedigree information, however, until now, no study has been developed using large-scale genomic markers in this breed. Pedigree information are widely used to investigate population parameters; however, they can neglect some estimates when compared to the use of genomic markers. Therefore, the objective of this study was to investigate the population structure and the genetic diversity of Indubrasil cattle using a...

Genome-wide detection of CNVs and their association with meat tenderness in Nelore cattle. Repositório Alice
SILVA, V. H. da; REGITANO, L. C. de A.; GEISTLINGER, L.; PÉRTILLE, F.; GIACHETTO, P. F.; BRASSALOTI, R. A.; MOROSINI, N. S.; ZIMMER, R.; COUTINHO, L. L..
Brazil is one of the largest beef producers and exporters in the world with the Nelore breed representing the vast majority of Brazilian cattle (Bos taurus indicus). Despite the great adaptability of the Nelore breed to tropical climate, meat tenderness (MT) remains to be improved. Several factors including genetic composition can influence MT. In this article, we report a genome-wide analysis of copy number variation (CNV) inferred from Illumina1 High Density SNP-chip data for a Nelore population of 723 males. We detected >2,600 CNV regions (CNVRs) representing 6.5% of the genome. Comparing our results with previous studies revealed an overlap in 1400 CNVRs (>50%). A total of 1,155 CNVRs (43.6%) overlapped 2,750 genes. They were enriched for...

High-throughput and cost-effective chicken genotyping using next-generation sequencing. Repositório Alice
PÉRTILLE, F.; BOSAGNA, C. G.; SILVA, V. H. da; BOSCHIERO, C.; NUNES, J. de R. da S.; LEDUR, M. C.; JENSEN, P.; COUTINHO, L. L..
Chicken genotyping is becoming common practice in conventional animal breeding improvement. Despite the power of high-throughput methods for genotyping, their high cost limits large scale use in animal breeding and selection. In the present paper we optimized the CornellGBS, an efficient and costeffective genotyping by sequence approach developed in plants, for its application in chickens. Here we describe the successful genotyping of a large number of chickens (462) using CornellGBS approach. Genomic DNA was cleaved with the PstI enzyme, ligated to adapters with barcodes identifying individual animals, and then sequenced on Illumina platform. After filtering parameters were applied, 134,528 SNPs were identified in our experimental population of chickens....

Identification of polymorphisms associated with production traits on chicken (Gallus gallus) chromosome 4. Repositório Alice
PÉRTILLE, F.; ZANELLA, R.; FELÍCIO, A. M.; LEDUR, M. C.; PEIXOTO, J. de O.; COUTINHO, L. L..
Genetic selection for production traits has resulted in a rapid improvement in animal performance and development. Previous studies have mapped quantitative trait loci for body weight at 35 and 41 days, and drum and thigh yield, onto chicken chromosome 4. We investigated this region for single nucleotide polymorphisms and their associations with important economic traits. Three positional candidate genes were studied: KLF3 (Krüeppel-like factor 3), SLIT2 (Slit homolog 2), and PPARGC1A (peroxisome proliferator-activated receptor gamma, coactivator 1 alpha). Fragment sequencing of these genes was conducted in 11 F1 animals, and one polymorphism in each gene was selected and genotyped in an F2 population (N = 276) and a paternal broiler line TT (N = 840)....
