Bras. 32(10):980-986, outubro 2012 980 RESUMO.-[Transferência de imunidade passiva e proteinograma sérico de bezerros das raças Crioula lageana e Holandesa preta e branca nos primeiros seis meses de vida.] O objetivo do presente trabalho foi veriϐicar e comparar a transferência de imunidade passiva e o proteinograma em bezerros da raça Crioula Lageana (CL) e Holandesa Preta e Branca (HPB). Foram utilizados dois grupos sendo 13 bezerros da raça Crioula Lageana e 10 da raça HPB. Amostras de sangue foram colhidas para a mensuração da proteína sérica total, eletroforese das proteínas séri-cas, atividade da gama-glutamiltransferase e concentração de IgG pelo método de turvação pelo sulfato de zinco nos períodos entre 24 e 36 horas de vida, 15, 30, 60, 90, 120, 150 calves. Two groups were utilized with 13 Criollo Lageano and 10 BWH calves. Blood samples were collected for the measurement of total serum protein, electrophoresis of serum proteins, activity of the gamma glutamyl transferase, and concentration of IgG by the method of the zinc sulfate turbidity in periods between 24 and 36 hours of life, 15, 30, 60, 90, 120, 150 and 180 days. Statistical analysis was performed by ANOVA and Tukey test at 5% signiϐicance level, and correlations between variables were calculated. Variations of serum proteins followed a pattern of physiological behavior over the ϐirst six months of life and production of immunoglobulins was active earlier in BWH calves and slower in the Criollo Lageano, without causing any impact on their health. Gamma globulin in the ϐirst days of life (24-36h) was correlated with IgG (r=0.87 for CL and r=0.89 for BWH), PTS (r=0.91 for CL and r=0.92 for BWH), Glob (r=0.99 for CL and r=0.98 for BWH) and GGT (r=0.14 for CL and r=0.83 for BWH). It was concluded that there was no failure in the transfer of passive immunity in Criollo Lageano calves but this failure occurred in the BWH calves. IgG values estimated by the zinc sulfate turbidity and serum proteins were considered good indicators of the transfer of passive immunity in calves between 24 and 36 hours of life. de ANOVA e Tukey ao nível de 5% de signiϐicância, e correlações entre as variáveis. As variações das proteínas séricas obedeceram a um padrão de comportamento ϐisiológico ao longo dos seis primeiros meses de vida e a produção ativa de imunoglobulinas foi mais precoce nos bezerros da raça Holandesa e mais lenta nos da raça Crioula Lageana, sem provocar qualquer impacto sobre a saúde dos mesmos. A gamaglobulina no primeiro dia de vida (24-36h) correlacionou-se com a IgG (r=0,87 CL e r=0,89 HPB), PTS (r=0,91 CL e r=0,92 HPB), Glob (r=0,99 CL e r=0,98) e GGT (r=0,14 CL e r=0,83 HPB). Conclui-se que não houve falha na transferência de imunidade passiva nos bezerros da raça Crioula Lageana e falha na raça Holandesa Preta e Branca. Os valores de IgG estimados pelo método da turvação pelo sulfato de zinco e das proteínas séricas foram bons indicadores da transferência de imunidade passiva nos bezerros entre 24 e 36 horas de vida.TERMOS ...

The purpose of this study was to investigate the genetic polymorphism of fifteen microsatellites loci in Brazilian (blue-egg Caipira) chickens. Samples were collected from 100 blue eggs of Caipira chickens from rural properties in the city of Dois Lajeados, RS. After DNA extraction, the fragments related to molecular markers LEI0248, LEI0221, LEI0214, LEI0192, LEI0217, LEI0254, LEI0194, LEI0212, MCW0371, ADL0278, LEI0234, MCW0183, MCW0216, MCW0330 and MCW0081 were obtained by polymerase chain reaction (PCR). The statistical analysis were carried out with the softwares ARLEQUIN 3.5 version and CER-VUS 3.0.3 version. The allelic and genotypic frequencies, deviations from Hardy-Weinberg equilibrium, estimates of observed (HO) and expected (HE) heterozygosity and polymorphic information content (PIC) were obtained for each marker locus. A total of 186 alleles from 15 loci were obtained, with sizes ranging of 83 to 490 base pairs. The medium number of alleles was 12.4, the HE was 0.76±0.14 and HO was 0.49±0.21 and PIC was 0.706. The first conclusion is that the microsatellites used are polymorphic and can be used to genetic studies in chickens. The second is that the "Caipira" chicken (blue eggs) population investigated has a great genic variability, which makes than an important source of genetic resources for future animal breeding programs. Genetic polymorphism of fifteen microsatellite loci in Brazilian (blue-egg Caipira) chickens nhas caipiras de ovos azuis analisada apresenta grande variabilidade gênica, o que as torna uma importante fonte de recursos genéticos, e que poderão, assim, serem utilizadas em futuros programas de melhoramento genético animal.

This research was performed by a multidisciplinary and interagency team and sought to determine the blood profile, total plasma protein and fibrinogen concentrations of clinically healthy adult Campeiro horses. A total of 138 horses (14 stallions, 74 non-pregnant and 50 pregnant mares)

RESUMOAmostras de sangue foram obtidas de 138 equinos registrados da raça Campeiro, com idade média de 9,7±5,4 anos, sendo 14 machos (10,15%) e 124 fêmeas (89,85%). Observaram-se valores médios da atividade sérica de GGT: 13,73±4,08 U/L; AST: 246,34±72,87U/L; ALT: 5,13±1,18U/L; FA: 284,32±53,33UI/L; CK: 132,54±72,25U/L; LDH: 511,38±143,65U/L; e das concentrações séricas de ureia: 38,65±12,62mg/dL e de creatinina: 1,24±0,24mg/dL. Os valores médios de AST, FA, ALT, ureia e creatinina foram semelhantes aos propostos na literatura para outras raças. Os valores de CK, GGT e LDH foram superiores aos comumente utilizados como referências. Não houve diferença nas concentrações de nenhum dos componentes séricos avaliados nas diferentes idades analisadas. Maiores valores médios nas concentrações de ureia e menores de creatinina foram observados nas fêmeas em relação aos machos, assim como a maior atividade sérica de FA em fêmeas gestantes em relação às éguas vazias. O perfil bioquímico sérico de equinos sadios da raça Campeiro apresenta variações peculiares que devem ser levadas em consideração na interpretação de exames laboratoriais.Palavras-chave: equino, Campeiro, análises clínicas, bioquímica sérica, enzimas GGT: 13.73 ABSTRACT Blood samples were obtained from 138 equines of the Campeiro breed with mean ages of 9.7±5.4 years, including 14 males (10.15%) and 124 mares (89.85%).

The aim of this study to measure the fractions of the total serum proteins of the Campeiro horse and identify the influences of biological variants. Blood samples were taken in 138 horses of the breed Campeiro for measuring the concentration of total serum protein by the biuret method. Serum concentrations of protein fractions were measured by electrophoresis using agarose gel. Groups were formed according to age, sex and reproductive condition. The average values of serum fractions: albumin (2.85±0.36g/dl), alpha 1 (0.28±0.11g/dl), alpha 2 (0.26±0.08g/dL) beta 1 (0.57±0.15g/dl), beta 2 (0.89±0.28g/dL), gamaglobulinas (1.86±0.34g/dL), albumin/globulin ratio (0.75±0.18) and 2.5% percentile and 97.5% had slight differences in relation to the reference interval proposed for the species. They observed higher values of alpha 1 and 2 globulins in the group from that had six to eight years old and gammaglobulins in group above 13 years old. Serum protein concentrations were similar in horses and mares and between non-pregnant and pregnant. Sex and pregnancy status did not affect serum proteinogram. Alpha and gammaglobulins have higher values as the age increases. Serum proteinogram of Campeiro horses shows variations that have to be considered in the interpretation of laboratory tests.
