Item Identificação e caracterização fenotípica dos grupos genéticos da raça Girolando nos rebanhos leiteiros do estado de Roraima(Universidade Brasil, 2017) Salgado, Léo Fernando de Faria; Frias, Danila Fernanda RodriguesThe dairy cattle in the State of Roraima is supported by crossbred Holstein x Gir cattle, more adapted to the tropical climate and traditional production systems. However, there is a need to adapt the genetic groups to the production systems and to raise awareness about the importance of the use of phenotypic visual evaluations as a tool to assist in the selection of animals. The objectives of the research were to identify the frequency and characterize the phenotype of the genetic groups ¼ Hol + ¾ Gir, ⅜ Hol + ⅝ Gir, ½ Hol + ½ Gir, ⅝ Hol + ⅜ Gir, ¾ Hol + ¼ Gir and ⅞ Hol + ⅛ Gir of the Girolando breed in the herds of the State of Roraima. The data were obtained from visual morphological evaluations to identify the genetic groups and to characterize the phenotype of the animals from August 2016 to February 2017. The following distribution of the frequency of genetic groups: 210 (21.26%) of the group ¼ Hol + ¾ Gir; 145 (14.68%) of the group ⅜ Hol + ⅝ Gir; 249 (25.20%) of the ½ Hol + ½ Gir; 166 (16.80%) of the group ⅝ Hol ⅜ + Gir; 126 (12.75%) of the ¾ Hol + ¼ Gir and 92 (9.3%) of the group ⅞ Hol + ⅛ Gir. In the phenotypic evaluations there were statistically significant differences (p <0.05) in the genetic group ¾ Hol + ¼ Gir for General Appearance (GA), in the genetic groups ⅝ Hol + ⅜ Gir and ⅞ Hol + ⅛ Gir for Body Capacity (CC), in the ½ Hol + ½ Gir group for Dairy Characteristics (CL) and in the groups ¾ Hol + ¼ Gir and ⅞ Hol + ⅛ Gir for Reproductive and Apparatus e aprumos (AR/A). The genetic group ½ Hol + ½ Gir presented superior characteristics in the Body Capacity (CC), the Milk Characteristics (CL) and the Reproductive and Apparatus e aprumos (AR/A), being better classified as to the type of Girolando breed demonstrating better characterization and uniformity by selective process.Item Quantificação e perdas econômicas por abscessos vacinais em bovinos oriundos da região norte do Brasil(Universidade Brasil, 2018) Silva, Danilo Mendes Hortêncio da; Dian, Paulo Henrique MouraInflammatory reactions causing abscesses are due to improper use of vaccines and / or medications. Vaccine abscesses bring concerns to breeders and entrepreneurs in the meat and meat industry because of the huge economic losses caused by the rejections of the parties involved in the vaccine reaction. The objective of this study was to measure carcass losses caused by vaccine abscesses. The study was carried out between July and December 2016, in a refrigerator in the municipality of Iranduba / AM. During the study, 20,909 bovine carcasses were collected from different states of northern Brazil, including the states of Amazonas, Roraima and Pará. In order to evaluate the losses caused by vaccine lesions in bovine carcasses, the animals were collected and weighed . A total of 20,399 cattle presented vaccine abscesses, 15,678 males and 4,721 females, presenting a general percentage of 97.56% of carcasses with vaccine lesions, which generated a discard of 7,673.4 kg of muscular portions of both sexes and provenances . It is concluded that the meat masses removed from the carcasses due to the formation of abscesses due to vaccination reaction cause significant losses to the producers, proving the necessity of insertion of cattle management in northern Brazil.Item Efeito do uso de biofertilizantes sobre parâmetros de produção e a modelagem matemática no preparo de canteiros no cultivo de rabanetes (RaphanussativusL.) = the effect of using biofertilizers over production parameters and mathematical modeling in garden preparation for radish cultivation (RaphanussativusL.)(Universidade Brasil, 2016) Martins, Wlamir do Nascimento; Andreani Junior, RobertoItem Proposta de instalação de observatório para questões socioambientais no município de Caraguatatuba/SP: estudo de necessidade e viabilidade = observatory of environmental issues for installation in Caraguatatuba/SP: necessity and viability study(Universidade Camilo Castelo Branco, 2015) Lopes, Paulo Eduardo; Lima, Leonice Domingos dos Santos CintraItem SYSCLIMATE – Sistema de monitoramento climático = SYSCLIMATE - Climate monitoring system(Universidade Brasil, 2019) Oliveira, André Marques de; Vanzela, Luiz SergioItem Comunicação municipal em Ribeirão Preto-SP: a “conversa” entre o poder público e a população para um ambiente sustentável = municipal communication in Ribeirão Preto, SP: the "conversation" between the public power and the population for a sustainable environment(Universidade Brasil, 2019) Gonçalves, Amanda Martins Ferreira; Lima, Leonice Domingos dos Santos CintraItem Programa educacional no currículo escolar para mitigar impactos ambientais por desastres naturais(Universidade Camilo Castelo Branco, 2015) Santos, Mércio Fabrício Souza; Bertipaglia, Liandra Maria AbakerItem Viabilidade do investimento empresarial em projetos para o meio ambiente abordando a contabilidade ambiental = viability of business investment in projects for the environment addressing environmental accounting(Universidade Brasil, 2019) Dias, Altino da Silva; Andreani Júnior, RobertoItem A influência da gestão de pessoas nas organizações frente aos impactos ambientais e a sustentabilidade = the influence of management of people in organizations to environmental impacts and sustainability(Universidade Brasil, 2019) Silva, Alessandre da; Castro, Cristina Veloso deItem Praças centrais de Caraguatatuba/SP: aspectos histórico-cultural, paisagísticos, arquitetônicos e de seus usuários = squares of central Caraguatatuba/SP: historical and cultural aspects, landscape, architectural and its users(Universidade Camilo Castelo Branco, 2015) Alcântara, Marli Aparecida dos Reis de; Vazquez, Gisele Herbst
