13. A survey of nellore breed based on nine molecular markers.
The Brazilian Nellore is a Bos indicus brees developed from animals imported from india up to the middle of this centry. Due to its high tolerance ti the tropical environment, the Nellore became the most popular beef cattle brees in Brazil. Besidies its importance as pure breed, it has been successfully used in commeercial crosses and in the composition of n

14. Characterization of mitochondrial genotypes in the foundation herd of the Canchim beef cattle breed
The Canchim (5/8 Charolais + 3/8 Zebu) beef cattle breed was developed at Southeast-Embrapa Cattle to take advantage of hybrid vigor and to combine the higher growth rate and beef quality of Charolais with tropical adaptations of Zebu. The development of three lineages (old, new, and crossbred) has increased its genetic basis. The genotypic origin (Bos tauru

15. Comparação da resposta imune induzida pela vacinação de bezerros Curraleiros e Nelores com Mycobacterium bovis-BCG. / Comparison of immune response induced by vaccination of calves Curraleiro and Nellore with Mycobacterium bovis-BCG.
A raça Curraleiro se desenvolveu e se adaptou à criação extensiva na região do cerrado brasileiro. Estes animais rústicos parecem ser mais resistentes às doenças endêmicas regionais. A resistência às infecções esta diretamente correlacionada a resposta imune do hospedeiro. Para verificar se existe alguma diferença na resposta imune de animais C

16. Mitochondrial control region genetic diversity and maternal ancestry of a Brangus-Ibage cattle populations
The genetic diversity of 277 nucleotides in the mitochondrial DNA control region (nt 15,964 to 16,240 in reference sequence) was analyzed in crossbreed beef cattle (Brangus-Ibage, 5/8 Bos primigenius taurus x 3/8 Bos primigenius indicus) as well as in some Nellore samples (B. p. indicus). Fifty-seven mutations were found in Brangus-Ibage comprising 18 haplot

17. Avaliação do impacto dos atributos de qualidade em tourinhos de elite da raça nelore comercializados em leilão: uma aplicação do método hedônico / Impact of quality attributes in the price of Nellore breed sold at auction: an application of the hedonic
O presente estudo mensura o impacto no preço dos atributos de qualidade nos tourinhos da raça Nelore comercializados em leilões por meio de uma metodologia específica, baseada na Teoria dos Preços Hedônicos. Para tanto, utilizou-se como amostra três leilões - 368 observações - de uma fazenda padrão, o Nelore Jandaia. Assim, os atributos dos animai

19. Análise do padrão de metilação do gene Peg3 em diferentes regiões de cérebro de bovinos da raça Nelore / Methylation pattern assay of Peg3 in several regions of Nellore cattle breed brain
The maternal behavior is essential to survival and development of mammalian offspring. Throughout pregnancy, females receive sensory and hormonal stimuli which promote modifications and prepare the mothers brain to the onset of maternal behavior patterns (for example, by increasing numbers of neurons producing oxytocin in the hypothalamus). Studies have iden

20. PRE AND POST WEANING PERFORMANCE EVALUATION FOR A MULTIBREED ABERDEEN ANGUS X NELLORE POPULATION USING DIFFERENT GENETIC MODELS / AVALIAÇÃO DO DESEMPENHO NA PRÉ E PÓS DESMAMA PARA UMA POPULAÇÃO BOVINA MULTIRRACIAL ABERDEEN ANGUS X NELORE UTILIZANDO DIFERENTES MODELOS GENÉTICOS
The objective of this study was to estimate the genetic effects that affect the pre and post weaning performances of animals, products from Aberdeen Angus (A) and Nellore (N) breeds crosses. In Article 1, there were used the weaning weights (PD) to test five genetic models (M). The M1, complete, containing the fix breed genetic effects direct additive (AD) a

21. Fatty acids profile of meat from Nelore and F1 Sindi Nelore cattle. / Ácidos graxos na carne de bovinos Nelore e F1 Sindi Nelore.
The objective of the present study was to compare the fatty acids (FA) profile in Longissimus dorsi (LDM) muscle of bovine Nelore and F1 Sindi Nelore. A completely randomized experimental design in 2 x 2 factorial arrangements (two genetic groups and two ages - 36 and 48 months) was used. Sixteen young bulls (eight Nelore and eight F1 Sindhi Nellore), castra

22. Estudo da influência de touro e de genearca da raça Nelore nos aspectos quantitativos e qualitativos de carcaça e da carne / Study of the influence of steer and breeders of Nellore in the quality and quantitative aspects of carcass and beef
The present study had as objective to estimate the genetic variability between steers and breed lines of Nellore, these represented by the greatest breeders, referred to carcass and beef quality. The animals used to collect the samples of carcass and beef belonged to the project of genetic improvement and evaluation to emission of CEIP-Special Certificate of

23. Non genetics effects on reproductive traits in Nellore female. / Efeitos não genéticos sobre as características reprodutivas de fêmeas da raça Nelore.
Reproductive performance of Nellore cattle herd, raised in pasture, without supplementation in dry season, in Baixada Litorânea region, Rio de Janeiro state, between 1980 and 2004, was analysed. The gestation length (GL) average was 293.30 + 0.13 days. The GL varied from 275 to 305 days, with a higher concentration (67.08%) between 287 and 299 days. The GL

24. Behavioral patterns of Angus, Caracu and Nelore beef cattle under grazing conditions with availability of shade and water for immersion / Aspectos comportamentais de bovinos das raças Angus, Caracu e Nelore a pasto frente à disponibilidade de recursos de sombra e água para imersão
Cattle under grazing conditions in tropical areas seek for shade as a thermal comfort resource often during the hottest periods of the day. The objective of this study was to evaluate and understand how cattle of different origins (Caracu - adapted taurus, Nellore - zebu and Red Angus - european taurus) use the thermal comfort resources, quantifying the freq
