Alternative Transcription of Peroxisome Proliferator-Activated Receptor Gamma in the Liver Is Associated with Fatness of Chickens Rev. Bras. Ciênc. Avic.
Parada,R; Malewski,T; Jaszczak,K; Kawka,M.
ABSTRACT The expression of four transcription variant of peroxisome proliferator-activated receptor gamma gene (PPARG) (XM_015292931.1; XM_015292932.1; XM_015292933.1 and NM_001001460.1) in the liver of broilers was measured and its correlation with abdominal fat weight and relative abdominal fat content was investigated. The study was conducted with 92 slow-growing crossbred chickens (Cobb males x indigenous Green-legged Partridge female chickens) divided into “fat” and “lean” groups, according to their abdominal fat yield. The NM_001001460.1 transcriptwas upregulated with ratio of means 4.26 (p≤0.01) in the “fat” group in relation to the “lean” group. Expression of this transcript was highly correlated with relative abdominal fat content (0.71, p≤0.01)...

Association of CSSM066 and ILSTS011 microsatellite markers and thyroglobulin gene SNP with backfat in Canchim cattle Scientia Agricola
Veneroni,Gisele Batista; Meirelles,Sarah Laguna; Oliveira,Henrique Nunes de; Alencar,Maurício Mello de; Gasparin,Gustavo; Gouveia,João José de Simoni; Cervini,Marcelo; Regitano,Luciana Correia de Almeida.
Canchim, a synthetic breed of cattle derived from the Charolais and Zebu group has been used in the beef-cattle industry in Brazil as an alternative for intensifying production. One of the main concerns with this breed is its poor fat deposition and consequently, there is an effort to increase the performance for this trait. The thyroglobulin gene is located in a QTL region for fat deposition, and reports describe the influence of a polymorphism in the 5´ leader sequence of that gene on marbling and subcutaneous fat thickness. This study analyzed the association of this polymorphism in the thyroglobulin gene, as well as of two flanking microsatellite markers, CSSM066 and ILSTS011, with backfat thickness in 987 Canchim beef cattle. The CSSM066 and ILSTS011...

Bovine gene polymorphisms related to fat deposition and meat tenderness Genet. Mol. Biol.
Fortes,Marina R.S.; Curi,Rogério A.; Chardulo,Luis Artur L.; Silveira,Antonio C.; Assumpção,Mayra E.O.D.; Visintin,José Antonio; Oliveira,Henrique N. de.
Leptin, thyroglobulin and diacylglycerol O-acyltransferase play important roles in fat metabolism. Fat deposition has an influence on meat quality and consumers' choice. The aim of this study was to determine allele and genotype frequencies of polymorphisms of the bovine genes, which encode leptin (LEP), thyroglobulin (TG) and diacylglycerol O-acyltransferase (DGAT1). A further objective was to establish the effects of these polymorphisms on meat characteristics. We genotyped 147 animals belonging to the Nelore (Bos indicus), Canchim (5/8 Bos taurus + 3/8 Bos indicus), Rubia Gallega X Nelore (1/2 Bos taurus + 1/2 Bos indicus), Brangus Three-way cross (9/16 Bos taurus + 7/16 Bos indicus) and Braunvieh Three-way cross (3/4 Bos taurus + 1/4 Bos indicus)...

The objective of this work was to evaluate the effects of single-nucleotide polymorphisms (SNPs) in the genes IGF1 (AF_017143.1:g.198C>T), MSTN (AF_320998.1:g.433C>A), MYOD1 (NC_007313:g.1274A>G) and MYF5 (NC_007303:g.1911A>G) on carcass and meat traits in Nelore (Bos indicus) and Nelore x B. taurus. A total of 300 animals were genotyped and phenotyped for rib eye area (REA), backfat thickness (BT), intramuscular fat (IF), shear force (SF) and myofibrillar fragmentation index (MFI). The effects of allele substitution for each SNP were estimated by regression of the evaluated phenotypes on the number of copies of a particular allele using the general linear model. The polymorphism at IGF1 was non-informative in Nelore animals. In crossbred...

Regost, Christelle; Arzel, Jacqueline; Cardinal, Mireille; Robin, Jean; Laroche, M; Kaushik, Sadasivam.
A study was undertaken with marketable size turbot to evaluate the effects of dietary fat levels on chemical composition. lipogenesis and flesh quality, Four experimental diets containing graded levels of fish oil in order to obtain 10%, 15%, 20% and 25% of crude fat were fed to triplicate groups of turbot (initial body weight of 660 g) for 12 weeks in full strength seawater at temperature of 17 degreesC. Nutrient digestibility was not influenced by dietary fat levels. The best growth performance was observed in fish fed 10% and 15% dietary fat. High dietary lipid levels led to higher fat deposition in whole fish, although lipid level in muscle remained low (1.1% in dorsal muscle and 1.7% in ventral muscle irrespective of diet), Significant subcutaneous...

Genome-wide characterization of genetic variations and regions under selection in broilers and layer chickens. Repositório Alice
BOSCHIERO, C.; MOREIRA, G. C. M.; GHEYAS, A.; GODOY, T. F.; GASPARIN, G.; MARIANI, P. D. S. C.; PADUAN, M..
Abstract: Background Meat and egg-type chickens have been selected for several generations for different traits. Artificial and natural selection for different phenotypes can change frequency of genetic variants, leaving particular genomic footprints throghtout the genome. Thus, the aims of this study were to sequence 28 chickens from two Brazilian lines (meat and white egg-type) and use this information to characterize genome-wide genetic variations, identify putative regions under selection using Fst method, and find putative pathways under selection.

Investigation of Leptin gene in broiler and layer chicken lines Scientia Agricola
Ninov,Kerli; Ledur,Mônica Corrêa; Alves,Helena Javiel; Rosário,Millor Fernandes do; Nones,Kátia; Coutinho,Luiz Lehmann.
Leptin, a polypeptide hormone secreted mainly by adipose tissue, plays an important role in feed intake regulation, energy metabolism and reproduction in several species. Its function has been intensively studied in mammals; however, in birds limited information is available. The cDNA sequence for chicken leptin has been reported, and high hepatic expression levels of leptin were associated with fat deposition in selected bird lines. However, controversies still remain concerning to the chicken leptin gene and several authors failed to amplify this gene from genomic DNA or cDNA. In view of this controversy and the importance of this gene, the present study aimed to investigate the leptin gene in a population of birds developed by Embrapa Swine and Poultry...

Performance and Carcass Yield of Broilers Fed Crude Glycerin at Differing Inclusion Levels Rev. Bras. Ciênc. Avic.
Broch,J; Henz,J; Nunes,R; Eyng,C; Savaris,V.
ABSTRACT This experiment was conducted to evaluate the effect of crude glycerin at differing inclusion levels on performance and carcass characteristics of broilers and litter moisture. 960 broilers of 21-42 days of age were used in a completely randomized design with six crude glycerin inclusion levels (0, 3, 6, 9, 12, 15%), with eight replicates containing 20 broiler chickens per experimental unit. There was a quadratic effect (p<0.05) for weight gain, feed intake and feed:gain ratio from 21 to 42 days of age. Higher levels of crude glycerin in diets increased (40.24%, p<0.05) the litter moisture and reduced (6.04%, p<0.05) the viability of of the birds. There were no effects (p>0.05) on carcass yield, breast, or liver percentages. However,...

Prospecting candidate SNPs for backfat in Canchim beef cattle. Repositório Alice
VENERONI, G. B.; MEIRELLES, S. L.; GROSSI, D. A.; GASPARIN, G.; IBELLI, A. M. G.; TIZIOTO, P. C.; OLIVEIRA, H. N.; ALENCAR, M. M. de; REGITANO, L. C. de A..
Canchim is a composite cattle breed developed in Brazil for beef production. One of the breeding objectives is to increase fat deposition. QTLs for fat thickness and/or marbling have been reported on BTA4 and BTA14. The IGFBP3 and DDEF1 genes, mapped to BTA4 and BTA14, respectively, affect adipogenesis. We looked for SNPs in the IGFBP3 and DDEF1 genes that could be associated with backfat thickness in Canchim beef cattle. For SNP identification, sires with the highest accuracy were ranked according to expected breeding value for fat thickness; the 12 extremes (six sires with the highest and six with the lowest expected breeding value for the trait) were chosen. Six regions of the IGFBP3 and 14 regions of the DDEF1 were sequenced using the Sanger method....
