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 Inclusão de polpa cítrica em dietas de grão inteiro de milho no confinamento de novilhos.(Universidade Brasil, 2019) Souza, Eduardo Freire de; Dian, Paulo Henrique MouraItem Concentração inibitória e bactericida mínima de ácidos orgânicos, associados ou não, frente à Escherichia coli e Salmonella spp.(Universidade Brasil, 2019) Rosique, Priscila E.; Dian, Paulo Henrique MouraItem Efeito da inclusão de pigmentantes naturais à dieta de frangos de corte sobre o desempenho. e coloração da pele do peito(Universidade Brasil, 2019) Biavatti, Hildene Andrey Zago; Mello, Juliana Lolli Malagoli de; Sgavioli, SarahItem Custos e benefícios da inseminação artificial nas pequenas propriedades leiteiras na região central de Rondônia.(Universidade Brasil, 2018) Morais, Sergio Batista de; Orlandi, Cássia Maria BarrosoItem Índices de tolerância ao estresse térmico e características fisiológicas de cabras Saanen no Tocantins(Universidade Brasil, 2019) Moraes, Eder Brasil de; Bertipaglia, Liandra Maria AbakerItem Software online de gestão da pecuária leiteira.(Universidade Brasil, 2019) Santos, Cleverson Oliveira dos; Pereira, Luiz Arthur Malta; Bertipaglia, Liandra Maria AbakerItem Eficiência do uso de cipermetrina sobre o controle de cascudinhos e desempenho do frango de corte.(Universidade Brasil, 2019) Souza, Christian Joppert Dias de; Santos, Elaine Talita; Sgavioli, SarahItem Características qualitativas da silagem de híbridos de milho com tecnologia VT PRO 2.(Universidade Brasil, 2019) Horbach, Ana Paula S. de Lazari; Dian, Paulo Henrique Moura
