Chitosan combined with technical cashew nut shell liquid improves in vitro rumi...
Vieira,Elis Regina de Queiroz; Goes,Rafael Henrique de Tonissi e Buschinelli de; Diaz,Tatiana Garcia; Osmari,Milene Puntel; Seno,Leonardo de OliveiraABSTRACT The objective was to evaluate the inclusion of chitosan (CHI) and technical cashew nut shell liquid (CNSLt) as natural feed additives in cattle diets on nutrient digestibility, ruminal fermentation, and in vitro gas production kinetics. We conducted a completely randomized design with 5×4 factorial arrangement, with 20, 35, 50, 65, and 100% Tifton 85 hay and four additives, monensin (200 mg/kg DM), CNS...
Importance of naturalized breeds as a base for the formation of exotic sheep (O...
Oliveira,Joyce Azambuja de; Egito,Andrea Alves do; Crispim,Bruno do Amaral; Vargas Junior,Fernando Miranda de; Seno,Leonardo de OliveiraAbstract Recent molecular tools and technologies have marked the discovery of the origin and domestication processes of a wide variety of species, using either genomic or mitochondrial molecular markers to provide input for selection programs, as well as the management and conservation of animal breeds. This study aimed to analyze genes of mitochondrial DNA of the following sheep (Ovis aries) breeds: Pantaneira...
Different intervals of behavioral observation in the scanning method and the re...
Oliveira,Geyssane Farias de; Caldara,Fabiana Ribeiro; Garcia,Rodrigo Garófallo; Seno,Leonardo de Oliveira; Marcon,Ádila Vasconcelos; Foppa,LucianaABSTRACT The objective of this work was to study the behavior of swine females in the grower phase using different observation intervals (continuous, 5, and 10 min). A total of 42 swine were used, 14 of them for each treatment, which were identified with a marker stick. These animals were observed using the focal sampling method for 5 h. The treatments were the observation intervals: continuous, every 5 min, an...
Prediction of weight and percentage of salable meat from Brazilian market lambs...
Ricardo,Hélio de Almeida; Roça,Roberto de Oliveira; Lambe,Nicola Ross; Seno,Leonardo de Oliveira; Fuzikawa,Ingrid Harumi de SouzaABSTRACT This study assessed the use of conformation and fatness scores of the EUROP sheep carcass grading system to predict weight and percentage of salable meat from Brazilian market lambs. Data were collected from in vivo, carcass, and retail production from 252 uncastrated lambs. Evaluated models included single regressions, two multivariate models, and one determined by the stepwise procedure. Conformation...
Compostagem de resíduo sólido de abatedouro avícola
Sunada,Natália da Silva; Orrico,Ana Carolina Amorim; Orrico Junior,Marco Antônio Previdelli; Centurion,Stanley Ribeiro; Oliveira,Arley Borges de MoraisEm virtude da grande demanda por proteína de origem animal, tem-se aumentado a produção de frangos de corte e consequentemente a geração de resíduos provenientes do abate de aves, sendo necessário o desenvolvimento de técnicas que permitam o aproveitamento e reciclagem desses materiais. Objetivou-se com a execução deste trabalho avaliar a eficiência da compostagem no tratamento e reciclagem do resíduo sólido de...
Adição de óleo e lipase sobre a biodigestão anaeróbia de dejetos suínos
Rodrigues,João Paulo; Orrico,Ana Carolina Amorim; Orrico Junior,Marco Antonio Previdelli; Seno,Leonardo de Oliveira; Araújo,Laura Costa deO objetivo do trabalho foi verificar a eficiência da co-digestão anaeróbia dos dejetos suínos com crescentes níveis de adição de óleo de descarte e lipase. Foram testadas quatro doses de óleos (8, 12, 16 e 20g kg-1 de substrato) e 3 doses de lipase (1, 2 e 3g kg-1 de substrato). Os parâmetros avaliados foram: redução de sólidos totais (ST), sólidos voláteis (SV) e número mais provável (NMP) de coliformes totais...
Reproductive efficiency of Nellore cows nursing Nellore or crossbred Simmental ...
Vargas Junior,Fernando Miranda de; Wechsler,Francisco Stefano; Oliveira,Marcus Vinicius Morais de; Seno,Leonardo de OliveiraThe objective of this study was to analyze the influence of genetic group (GG) of the calf during gestation, mobilization of body reserves and period of postpartum anestrus in Nellore cows. Thirty-seven primiparous and multiparous cows were used: 24 gave birth to Nellore (NEL), and 13 gave birth to ½ Simmental × ½ Nellore (SIM) calves. According to the date of calving, cows were divided into three blocks, with ...
Marinade with alkaline solutions for the improvement of pork quality
Santos,Viviane Maria Oliveira dos; Caldara,Fabiana Ribeiro; Seno,Leonardo de Oliveira; Feijó,Gelson Luis Dias; Paz,Ibiara Correia de Lima AlmeidaThe objective of this work was to evaluate the effects of alkaline solution marinades on the characteristics of pork subjected to post-mortem pH decrease in pig muscle. The pH of carcasses was measured in a commercial slaughterhouse (n = 526), 45 min after slaughtering (pH45) and, then, the carcasses were divided into the groups with pH45<5.7 or pH45>5.7. Ten samples of the longissimus dorsi muscles of each ...
Genetic parameters for milk, fat and protein yields in Murrah buffaloes (Bubalu...
Aspilcueta-Borquis,Rusbel Raúl; Sesana,Roberta Cristina; Berrocal,Milthon Honorio Munoz; Seno,Leonardo de Oliveira; Bignardi,Annaiza BragaThe objective of the present study was to estimate genetic parameters for test-day milk, fat and protein yields and 305-day-yields in Murrah buffaloes. 4,757 complete lactations of Murrah buffaloes were analyzed. Co-variance components were estimated by the restricted maximum likelihood method. The models included additive direct genetic and permanent environmental effects as random effects, and the fixed effec...
