1. UTILIZAÇÃO DE MODELOS DE REGRESSÃO ALEATÓRIA PARA OBTENÇÃO DE PARÂMETROS GENÉTICOS DE BOVINOS DA RAÇA TABAPUÃ
Resumo Este trabalho utilizou 28.643 registros de pesos, do nascimento aos 660 dias de idade, de 6.471 animais da raça Tabapuã para estimar componentes de variância, covariância e parâmetros genéticos, utilizando o modelo de regressão aleatória. Foi utilizado algoritmo de busca AIREML através do método da máxima verossimilhança restrita pelo prog

2. Efeitos do plasma sangüíneo sobre o desempenho bacteriano e estrutura intestinal de leitões recém desmamados em diferentes idades / Effects of spray dried plasma on wall structure and on the microbiological colonization in the gut of piglets weaned at different ages
Aiming to determining whether the plasma has other effects on piglets weaned at different ages that are not only related to feed intake increased, three trials were conducted. In trial 1, sixteen piglets weaned at 21 days of age were used in an experiment with randomized blocks design with four treatments (diets with 0.0, 2.5, 5.0 and 7.5% of plasma), four r

3. Desempenho de bezerros da raça holandesa com desaleitamento aos 28 ou 56 dias de idade, com ou sem aditivo à base de oligossacarídeo de manana / Performance of holstein bull calves weaned at 28 or 56 days of age, with or without additive based on mannanoligosaccharide
Vinte e quatro bezerros da raça Holandesa foram utilizados num experimento com delineamento completamente casualizado, em arranjo fatorial 2x2 (desaleitamento aos 28 ou 56 dias, com ou sem a adição de oligossacarídio de manana à dieta), e seis repetições por tratamento. Não houve interação entre os fatores período de aleitamento e uso ou não de a

4. FEED INTAKE, YIELD AND COMPOSITION OF MILK FROM EWES AND PERFORMANCE OF SINGLE OR TWIN LAMBS / CONSUMO DE NUTRIENTES, PRODUÇÃO E COMPOSIÇÃO DO LEITE DE OVELHAS E DESEMPENHO DE CORDEIROS ORIUNDOS DE PARTO SIMPLES OU DUPLO
The experiment was conducted in the Sheep Division of the Universidade Federal de Santa Maria (UFSM) to determine nutrient intake, and yield and composition of milk from ewes, as well as its relationship with performance and carcass characteristics of either single or twin lambs. Sixteen multiparous ewes from an alternate crossing between Texel and Ile de Fr

5. Desempenho de bovinos superprecoces não castrados ou castrados em diferentes idades criados no sistema pasto/suplemento / Performance of young beef cattle uncastraded or castraded in grazing reared in pasture system/supplement
This work was developed in two chapters. The objective of the study described in the first chapter was to evaluate the performance nutritional and carcass traits of grazing young bulls castrate at different ages or not, supplemented or not. Fourty seven crossbred Nellore young bulls with initial age of 120 30,1 were used, housed in paddocks of Brachiaria dec

6. Avaliação do desempenho de Suínos Alimentados com Mananoligossacarídeos (MOS) / Effects of mannan oligosaccharides on gilts and litters performance
The present study evaluated the effects of mananoligossacarides (MOS) as a feed additive on the performance of primiparous sows in late gestation and lactation, as well as on performance and health status of their progeny up to 65 days of age. The experiment was conducted in the Laboratory of Swine Research (FMVZ/USP) Pirassununga SP. For this purpose a comp

7. Desempenho produtivo de bezerros holandeses submetidos a diferentes idades de desaleitamento e de fornecimento de feno / Productive performance of Holstein calves submit at diferennt ages of weaning and hay careted
There is complex interaction between feeding milk purpose, when talk about period of feeding and intake of solid feed, between concentrate intake and hay, roughages age and concentrate should be given and its interactions about the performance of calves. This work was carried on with objective to evaluate the performance and calves intake in two ages of wean

8. Behavior of piglets in function of the protein source in the diet after the weaning / Comportamento de leitões em função da fonte protéica na dieta e idade ao desmame
Two experiments were conduced, the first using 48 piglets, weaned to the 21 days of age, and with initial weight of 5,60 0,75 kg, distributed at random in three treatments and sixteen repetitions with an animal for experimental unit, with the objective of evaluating the behavior after the weaning fed with diets containing different protein sources. The treat

9. Influence of genetic and environmental factors on production and reproduction traits in a nellore cattle herd in Goias state HERD IN GOIAS STATE / Estudo da influência de fatores genéticos e ambientais sobre as características produtivas e reprodutivas em um rebalho de bovinos da raça Nelore no Estado de Goiás
The objective of this study was evaluate genetic and non-genetic factors which influence production and reproduction traits in a Nelore herd in Goiás state. Direct and maternal heritabilites and direct and common environmental effects were evaluated for birth weight (PN), weaning weight corrected for 205 days (P205), age at first calving (IPP), calving inte

10. Substitution of the spray-dried milk protein by the spray-dried blood plasma protein in diets for piglets weaned at 28 days of age / Substituição da proteína do leite em pó por proteína do plasma sangüíneo em pó em dietas para leitões pós-desmame aos 28 dias
Objetivando-se avaliar níveis de plasma sanguíneo em pó (PSP) em dietas para leitões desmamados aos 28 dias de idade foi realizado um experimento utilizando 128 leitões com peso inicial médio de 7,64 0,103 kg, distribuídos em delineamento em blocos, composto por quatro tratamentos, oito blocos e quatro animais por unidade experimental. Os tratamentos

11. EFFECT OF THE INCLUSION OF THE DIRECT-MATERNAL COVARIANCE ON THE ESTIMATIVE OF GENETIC PARAMETERS AND ON THE PREDICTION OF THE GENETIC VALUES FOR WEIGHT GAIN FOR CATTLE / EFEITO DA INCLUSÃO DA COVARIÂNCIA GENÉTICA DIRETA-MATERNA, NA ANÁLISE PARA ESTIMAR PARÂMETROS GENÉTICOS E PREDIZER VALORES GENÉTICOS PARA GANHO DE PESO EM BOVINOS DE CORTE.
The present study has as objective to evaluate the effect of the inclusion in the model of analysis, the covariance between the additive genetic direct and maternal effects, on the estimation of genetic parameters for average daily gain from birth to weaning (GMDND) and from weaning to 550 days of age (GMDDS), and on the prediction of genetic values and rank

12. Antibody-Mediated Protection against Infection with Helicobacter pylori in a Suckling Mouse Model of Passive Immunity▿
Studies of active immunization against Helicobacter pylori indicate that antibodies play a minor role in immunity. There is also evidence, however, that the translocation of antibodies in the stomach may be insufficient to achieve functional antibody levels in the gastric lumen. We have used a suckling mouse model of passive immunity to determine if perorall
