Avaliou-se a resposta de cabras tratadas com r-bST no protocolo de sincronização de estro. Foram utilizadas 26 cabras Toggenburg, divididas em dois tratamentos: T1 (n=13), tratadas com quatro injeções de ..250mg de rbST, a intervalos de 14 dias, e T2 (n=13), tratadas com solução salina (controle). Na semana seguinte à última injeção da r-bST, colocou-se o dispositivo intravaginal com progesterona (dia 0), previamente utilizado por cinco dias, e injetou-se PGF2.. (22,5µg) nos animais dos dois tratamentos, e o dispositivo foi retirado no dia 6. Todas as fêmeas em estro foram submetidas à monta natural. A porcentagem de animais em estro e a taxa de gestação foram 76,9 e 70,0 e 84,6 e 72,7%, no T1 e T2, respectivamente. Não houve diferença (P>0,05) na duração do estro, no intervalo tratamento-início do estro, no número de ovulações, nos intervalos: início e final do estro à ovulação e retirada do dispositivo à ovulação entre os animais dos dois tratamentos. O diâmetro médio dos folículos ovulatórios das fêmeas não diferiu (P>0,05). Durante a permanência do dispositivo, as concentrações séricas de progesterona apresentaram valores semelhantes (P>0,05) entre as cabras de T1 e T2. A r-bST não afetou a sincronização de estro.

The European Union Agency for Fundamental Rights (FRA), the EU body responsible for advising EU institutions on fundamental rights, is equipped with a Fundamental Rights Platform (FRP) to ensure an on-going and structured exchange of information and feedback between the FRA and Civil Society. When the FRA was founded in 2007, there was little pre-existing knowledge on how to design such a Platform; hence, the development of the relationship between the FRA and Civil Society over the first five years proved an interesting experiment. Although the Platform was never intended as a mechanism of democratic co-decision making, it is far more than a loose marketplace where Civil Society actors across the spectrum of fundamental rights themes gather. The Platform offers channels of consultation and exchange not only among the participants but also with the FRA. It allows for cross-pollination, ensuring informed grassroots input into FRA work and FRA expertise flow to Civil Society actors. This synergetic relationship builds upon both the self-organising forces of Civil Society and the terms of references of the FRP as defined by the FRA. The Platform allows to find a certain unity in the remarkable diversity of fundamental rights voices. To what degree, however, the Platform’s dynamics allow the transformation of sometimes ‘compartmentalised’ single human rights discussions into wider trans-sectoral and transnational debates within the Human Rights Community depends on the motivation and the interest(s) of the different Civil Society players.

Objetivou-se, no presente estudo, avaliar a produção de leite de caprinos leiteiros da região sudeste do Brasil, com intuito de verificar os fatores de meio e estimar os parâmetros genéticos pelo método dos mínimos quadrados (MMQ). Os controles de 1336 lactações foram inicialmente ajustados pela função multifásica (difásica) e calculou-se a produção de leite total (PLT). Os dados foram provenientes de sete propriedades e três raças (Parda Alpina, Saanen e Toggenburg). A média e o erro-padrão da PLT estimados pelo MMQ foram de 635,31 ±39,75 kg. A interação ano x estação do parto influenciou a PLT. em um dos anos estudados, a PLT foi menor para as cabras paridas no final da estação. Nas três estações de parto, observou-se comportamento quadrático da PLT, em função dos anos de parto. Para as três estações, a PLT aumentou de 1986 até meados de 1990, decrescendo em seguida. A idade de máxima PLT foi observada aos 46,65 meses. Das três raças estudadas, observou-se que as raças Parda Alpina e Saanen apresentaram alternância de superioridade na PLT em algumas fazendas, porém maiores que a Toggenburg. Os coeficientes de herdabilidade e repetibilidade da PLT estimados pelo MMQ foram de 0,296 ± 0,079 e 0,277 ± 0,033, respectivamente. Estes resultados revelam baixa confiabilidade em poucas observações dessas características ou na inconsistência das estimativas da função multifásica. Como a PLT é uma característica limitada ao sexo, sugere-se o teste de progênie como método de seleção mais eficiente para os reprodutores e uso de inseminação artificial como processo de disseminação do material genético selecionado.

The kidding intervals (IDP) of dairy goats raised in Southeastern Brazil were studied to quantify the influence of environmental factors and to estimate genetic parameters by means of least squares (MMQ) and restricted maximum likelihood (REML). The data analyzed were obtained from five farms and three breeds (Alpine, Saanen, and Toggenburg). The overall mean and standard error of IDP, as estimated by MMQ, were 339 +/- 12.70 days. The interaction of year x season of parturition influenced IDP. In two of the years studied, goats kidding at the end of the kidding season showed a shorter IDP when compared to those that were kidding after the end of the season. A quadratic trend of IDP over years was observed across the three kidding periods. For the three seasons. IDP increased from 1986 until mid-1989 and decreased thereafter. The heritability and repeatability of IDP, as estimated by MMQ and REML, were: 0.046 +/- 0.071 and 0.103 +/- 0.043, and 0.00026 and 0.08411, respectively. These estimates indicate that little genetic gain can be expected from selection for this trait.

Data from 2439 goats of the Saanen, Alpine, Anglo Nubian and Toggenburg breeds recorded from 1976 to 2009 by the Association of Goats and Sheep Breeders of Minas Gerais were used in principal component analysis. After consistency of data, six morphological variables (thorax perimeter, body length, withers height, height, width and length of the rump) and 12 variables related to breed standard score and fitness (breed characteristic, head, palette and topline, feet and legs, dairy type, body capacity, udder, rear and front ligament, udder texture, teat and final score) were analyzed. Based on the magnitude of the eigenvalue (lower than 0.7), eleven variables considered redundant were discarded, resulting in reduced costs of technician labor to evaluate the animals. Maintenance of records on height, length, rump width, breed characteristic, dairy type, front ligament and udder texture is recommended.

BACKGROUND In 2006, bluetongue virus serotype 8 (BTV-8) was detected for the first time in central Europe. Measures to control the infection in livestock were implemented in Switzerland but the question was raised whether free-ranging wildlife could be a maintenance host for BTV-8. Furthermore Toggenburg orbivirus (TOV), considered as a potential 25th BTV serotype, was detected in 2007 in domestic goats in Switzerland and wild ruminants were considered a potential source of infection. To assess prevalences of BTV-8 and TOV infections in wildlife, we conducted a serological and virological survey in red deer, roe deer, Alpine chamois and Alpine ibex between 2009 and 2011. Because samples originating from wildlife carcasses are often of poor quality, we also documented the influence of hemolysis on test results, and evaluated the usefulness of confirmatory tests. RESULTS Ten out of 1,898 animals (0.5%, 95% confidence interval 0.3-1.0%) had detectable antibodies against BTV-8 and BTV-8 RNA was found in two chamois and one roe deer (0.3%, 0.1-0.8%). Seroprevalence was highest among red deer, and the majority of positive wild animals were sampled close to areas where outbreaks had been reported in livestock. Most samples were hemolytic and the range of the optical density percentage values obtained in the screening test increased with increasing hemolysis. Confirmatory tests significantly increased specificity of the testing procedure and proved to be applicable even on poor quality samples. Nearly all samples confirmed as positive had an optical density percentage value greater than 50% in the ELISA screening. CONCLUSIONS Prevalence of BTV-8 infection was low, and none of the tested animals were positive for TOV. Currently, wild ruminants are apparently not a reservoir for these viruses in Switzerland. However, we report for the first time BTV-8 RNA in Alpine chamois. This animal was found at high altitude and far from a domestic outbreak, which suggests that the virus could spread into/through the Alps. Regarding testing procedures, hemolysis did not significantly affect test results but confirmatory tests proved to be necessary to obtain reliable prevalence estimates. The cut-off value recommended by the manufacturer for the screening test was applicable for wildlife samples.
