Maternal-offspring behavior of Guzerat beef cattle
Pires,Bianca Vilela; Freitas,Luara Afonso de; Silva,Gabriele Voltareli da; Mendonça,Gabriela Geraldi; Savegnago,Rodrigo PelicioniAbstract: The objective of this work was to evaluate the characteristics of the maternal-offspring behavior of Guzerat bovines (Bos indicus) and the influence of this behavior on herd losses. A total of 73 gestating cows (multiparous and primiparous) and their respective calves were evaluated for the following behavioral traits: contact period between cow and calf (CPCC), cow age at calving, teat conditions, ca...
Somatic cell count obtained by Ekomilk Scan® and correlations with other method...
Gonçalves,Ana Carolina Siqueira; Roma Júnior,Luiz Carlos; Privatti,Rafaela Torrezan; Salles,Márcia Saladini Vieira; Paz,Claudia Cristina Paro deABSTRACT: The study aimed to evaluate the equipment Ekomilk Scan® as an alternative to somatic cell count (SCC) in milk. For this individual cow milk samples of various ages and different stages of lactation in northeastern state of São Paulo region were collected. The analyzes performed were divided into variables related to the equipment: repeatability and reproducibility, and variables that could influencing...
Estimates of genetic parameters and cluster analysis for worm resistance and re...
Oliveira,Elisa Junqueira; Savegnago,Rodrigo Pelicioni; Freitas,Luara Afonso de; Freitas,Anielly Paula; Maia,Suellen Rodrigues; Simili,Flávia FernandaAbstract: The objective of this work was to estimate genetic parameters for traits related to resistance to endoparasites in Santa Inês sheep, for a possible inclusion in sheep breeding programs, as well as to evaluate the additive genetic pattern of the animals using cluster analyzes, in order to assess whether there are groups within the population that can be used as candidates for selection for resistance t...
Associação genética entre ocorrência de mastite clínica e produção de leite em ...
Oliveira,Elisa Junqueira; Bignardi,Annaiza Braga; Santana Junior,Mário Luiz; Paz,Claudia Cristina Paro de; Zadra,Lenira El FaroRESUMO: O objetivo deste trabalho foi estimar os parâmetros genéticos e fenotípicos para ocorrência da mastite clínica (MC) e para a produção de leite acumulada até 305 dias (PR305) e estudar as associações genéticas entre elas, usando informações de 11.738 lactações de 5.084 vacas de um rebanho da raça Holandesa, paridas entre 1995 a 2010. Os componentes de covariância foram obtidos por abordagem Bayesiana, so...
REPRODUCTIVE TRAITS SELECTION IN NELORE BEEF CATTLE
Moreira,Heverton Luis; Buzanskas,Marcos Eli; Munari,Danisio Prado; Canova,Érika Breda; Lôbo,Raysildo Barbosa; Paz,Claudia Cristina Paro deGenetic breeding programs of beef cattle in Brazil are including new features, mainly related to reproductive efficiency.Thus, it is necessary to study the effectiveness of selection and quantify genetic gain for these traits in herds. This study estimated genetic and phenotypic parameters and genetic trends for reproductive traits used in breeding programs for Nelore beef cattle. The traits studied were the sc...
Performance and rumen parameters of crossbred dairy cows fed two sugarcane vari...
Lima,Maria Lúcia Pereira; Simili,Flávia Fernanda; Medeiros,Maria Izabel Merino de; Balieiro Neto,Geraldo; Ribeiro,Enilson GeraldoTwo sugarcane varieties (IAC86-2480 and IAC91-2195) combined or not with soybean hulls (SH), partially replacing corn in concentrate, were included in the diet of crossbred dairy cows to evaluate the effects on feed intake, milk production, milk composition and rumen parameters of crossbred cows. The sugarcane varieties (IAC86-2480 and IAC91-2195) and concentrate compositions (with and without SH) were analyzed...
Hydrocyanic acid content and growth rate of sorghum x sudangrass hybrid during ...
Simili,Flávia Fernanda; Lima,Maria Lúcia Pereira; Medeiros,Maria Izabel Merino de; Paz,Claudia Cristina Paro de; Ruggieri,Ana ClaudiaIn central Brazil after soybean or other annual agricultural species is harvested, sorghum hybrids are planted in the fall in order to establish pastures for grazing animals. This study conducted for two consecutive years aimed at quantifying the contents of hydrocyanic acid in the leaves and determining plant height, forage dry matter yield and the leaf/stem ratio for sorghum hybrid 1P400 at different ages. St...
Respostas do híbrido de sorgo-sudão às adubações nitrogenada e potássica: carac...
Simili,Flávia Fernanda; Gomide,Carlos Augusto de Miranda; Moreira,Andréia Luciane; Reis,Ricardo Andrade; Lima,Maria Lúcia PereiraA pesquisa foi instalada no Setor de Forragicultura da FCAV/UNESP-Jaboticabal, para avaliar o híbrido de sorgo-sudão AG 2501C no outono e inverno. O manejo da pastagem foi conduzido, simulando o sistema de lotação intermitente. O experimento foi desenvolvido de março a setembro de 2002. A forrageira foi submetida a nove tratamentos: três doses de N (100, 200 e 300 kg/ha) e três doses de K (0, 80 e 160 kg/ha de ...
Amostragem, diversidade e sazonalidade de Hemerobiidae (Neuroptera) em Coffea a...
Lara,Rogéria Inês Rosa; Freitas,Sérgio de; Perioto,Nelson Wanderley; Paz,Claudia Cristina Paro deEste estudo teve por objetivo avaliar métodos de amostragem, abundância sazonal e diversidade da população de Hemerobiidae associada a cultivo de café Coffea arabica L. cv. Obatã em Cravinhos, São Paulo, Brasil. Para tanto foram realizadas amostragens semanais no período de maio de 2005 a abril de 2006. Os métodos de amostragem utilizados foram: rede de varredura e armadilhas de Möericke e luminosa. Foram colet...
Differential growth retardation and Myofibrillar fragmentation in rats submitte...
Leonardo,Eric Franchi; Delgado,Eduardo Francisquine; Bagaldo,Adriana Regina; Lanna,Dante Pazzanese Duarte; Paz,Claudia Cristina Paro deFeed regimens alter muscle growth rate, hence they might impact the proteolytic system involved in tenderization during meat conditioning. The aim of this project was to verify the effects of feed restriction regimens on muscular and animal growth and their impact on postmortem myofibrillar fragmentation. The regimens were: 1) Feeding ad libitum for 11 d (Al/2); 2) Feed restriction (60% of Net Energy for mainte...
