| We empirically investigate the effects of beef packer concentration and size efficiencies, packer procurement and pricing methods, and other market variables and quality characteristics on the prices paid by packers for slaughter cattle. We find that packers pay less for fed cattle in more concentrated regions. However, we find that concentration is only one of numerous market factors determining fed cattle prices and less important than many. Quality variables controlled by sellers, like cattle type, are more important in determining the price paid by packers than packer concentration, size economies, procurement methods, or other variables outside seller control. |

| This survey was carried out in slaughter plants in the southern of the Espírito Santo State in order to study the causes and the percentages of liver condemnation during post mortem examination from 2008 to 2010. The main reasons for the condemnation of cattle livers in routine meat inspection of the State Inspection Service were fasciolosis (62.2%), telangiectatic (12.2%), bleeding (5.9%), abscess (5.2%), cysticercosis (4.0%), adherence (3.7%), infection (1.9%) and tuberculosis (1.1%). The hepatic fascioliasis was responsible for most of the lover condemnations, constituting a major challenge to livestock health in the south of the Espírito Santo. |

| A mosca-dos-chifres, Haematobia irritans e considerada a maior praga dos bovinos nos Estado Unidos (Drummond et al., 1981) e uma das maiores pragas na Australia, sendo tambem muito importante na Europa. No Brasil, a mosca ocorre praticamente em todo o Pais, e os pecuaristas, especialmente da regiao do Cerrado, tem apontado o inseto como responsavel por grandes prejuizos. Sua introducao ocorreu por volta de 1976 na regiao norte, e a partir dai dispersou-se rapida e eficientemente. No Distrito Federal, a mosca foi observada pela primeira vez em 1990 (Saueressig, 1990). Por ser uma praga relativamente nova, existe pouca informacao sobre sua epidemiologia, controle e possiveis danos (nivel e grau de prejuizo) nessa regiao. A partir da sua dispersao no Brasil,... |

| No Oeste da Bahia, a revitalização e o desenvolvimento da pecuária de corte têm sido considerados como prioridades. Nesse sentido, a Secretaria de Agricultura, Irrigação e Reforma Agrária (SEAGRI) resolveu, sob a coordenação da Empresa Baiana de Desenvolvimento Agrícola S/A (EBDA), tomar a iniciativa de elaborar um plano de ações que contemplem esta demanda. Esse relatório tem como objetivo oferecer subsídios para elaboração do referido plano e fundamenta-se numa abordagem participativa com a comunidade local. O declínio da pecuária é caracterizado por uma redução do rebanho, manifestada pela substituição de venda de boi gordo por bezerro desmamado. Grande parte das pastagens encontra-se degradada ou em processo de degradação. A falta de capacitação dos... |

| Twenty-eight Brangus cattle were used to determine the effect of copper and selenium supplementation on the carcass characteristics, fatty acid composition of the longissimus dorsi muscle and on the copper and selenium concentrations in the liver. The treatments were: no supplementation of copper or selenium; 2 mg Se/kg DM as sodium selenite; 40 mg Cu/kg DM as copper sulfate; and 2 mg Se/kg DM as sodium selenite and 40 mg Cu/kg DM as copper sulfate. The fat thickness, rib eye area and fatty acid composition of the longissimus dorsi muscle were not affected by treatments. There was no effect on carcass yield and cooling loss with the supplementation of copper, selenium or selenium × copper in the levels studied. For the ether extract concentration in the... |

| The objective of this study was to evaluate the correlations existing between nutrient intake and ingestive behavior of crossbred steers in the post-weaning phase on Brachiaria brizantha cv. Marandu, during the rainy period. Twenty-two steers were distributed into a completely randomized design, with two types of supplement and eleven replications, managed under rotational grazing, in a 6.5 ha area. Pearson’s Linear Correlation analysis was performed between the behavior variables and the performance variables values. The correlation coefficients were tested by the t test. The average daily gain (ADG) showed positive correlation with the times spent ruminating and eating at the trough and total chewing time. Positive correlation was observed between the... |

| Objectives were twofold: Determine key factors influencing preconditioning cost and returns; and determine the premium for age and source verified, preconditioned calves sold at a public livestock market. Data provided by the Samuel Roberts Noble Foundation show preconditioning returns depend significantly on number of days preconditioned, average daily gain, and cost of vaccinations, hay, feed, and mineral. Noble Foundation cooperators received a premium for age and source verified, preconditioned feeder cattle when sold at market. Significant coefficients averaged across five sales conclude that Noble Foundation management practices receive a $2.49/cwt premium when compared to all other cattle sold at market. |

| Different culture systems have been studied that support development of somatic cell nuclear transfer (SCNT) embryos up to the blastocyst stage. However, the use of sequential and two-step culture systems has been less studied. The objective of the present study was to examine the developmental potential and quality of bovine SCNT embryos cultured in different two-step culture media based on KSOM, SOF and the macromolecules FBS and BSA (K-K/FBS, K-S/BSA and K-K/BSA, respectively). No differences were observed in the cleavage rate for any of the culture systems. However, there was a significant difference (P<0.01) in the rate of blastocyst development, with the K-K/ FBS culture system yielding a higher rate of blastocysts (28%) compared to other... |

| The NAHMS Dairy '96 Study was designed to provide both participants and the industry with information on the nation's dairy animal population for education and research. This report contains demographic changes of the U.S. and world dairy industry from a historical perspective from data provided by the National Agricultural Statistics Service (NASS), Census of Agriculture, and Foreign Agriculture Service. Results of two NAHMS national studies overview changes in the U.S. dairy industry in the 5-year period of 1991 to 1996. The 1991 National Dairy Heifer Evaluation Project included herds of 30 or more milk cows and heifer-rearing operations in 28 states representing 83 percent of U.S. milk cows. NAHMS Dairy '96 described dairy production for operations... |

| The NAHMS Dairy '96 Study was designed to provide both participants and the industry with information on the nation's dairy animal population for education and research. The USDA's National Agricultural Statistics Service (NASS) collaborated with NAHMS to select a statistically valid sample yielding 2,542 producers. Included in the study were 20 states that represented 83.1 percent of the U.S. milk cows as of January 1, 1996. Veterinary Medical Officers (VMO's) and Animal Health Technicians (AHT's) collected data for Part III from 1,219 operations that had 30 or more milk cows on January 1, 1996, from February 20 through May 24, 1996.

| Trinta e cinco vacas de rebanhos leiteiros da região Norte do estado do Paraná, com histórico de abortamento, foram pesquisadas sorologicamente para verificar a presença de anticorpos contra Neospora caninum, Toxoplasma gondii, Leptospira spp., Brucella abortus, BHV-1 e BVDV. Vinte e uma vacas apresentaram títulos sorológicos compatíveis com infecção. Todas elas, soropositivas para N. caninum, foram também soropositivas para outros agentes infecciosos, sugerindo a possibilidade de associação desses agentes nos problemas reprodutivos de bovinos, no estado do Paraná. |

| The present study aims to identify dermatological alterations due to the work carried out by women on dairy farms and presents an intervention process on dermatology health with women working in these locations. It is a quasi-experimental study, in an intervention form, in which each subject is independent. It was performed with 20 women working on a dairy farm in Rio Grande, Rio Grande do Sul, Brazil, between July and October 2011. Most (60%) women identified dermatological changes due to the work. During the intervention, dermatological care action was focused on. The knowledge of these results offers valuable information for those who teach and advice people about dermatological care in rural working places, where such rates of occurrence are high. |
