Resumo: | To evaluate the inclusion of yeast extract (YE), on the diets of the pigs replacing partially the plasma over the performance (FW – final weight, DWG – daily weight gain, DFI – daily food intake and FC – food conversion) and the pigs intestine morphometry at the age of 21 days, two experiments were carried out. In the first experiment, 120 animals were used, from 21 days to 35 days of age, and distributed in experimental randomized block design, constituted by five diets (4.0 % of PL; 2.0 % of PL with 0.0; 1.0; 2.0 or 3.0% of YE) six replicates and four pigs per experimental unit. To evaluate the duodenum and jejunum morphometry, a 35 days old subject was slaughtered per experimental unit. In the second experiment 105 piglets were used, from 21 days to 60 days of age. From the weaning (21 days of age) to 35 days of age, the piglets were fed with a diet that generated the best performance on the first experiment. At the age of 36 days, the piglets were distributed in experimental randomized block design, constituted by five diets (2.0 % of PL; 1.0% of PL with 0.0; 1.0; 2.0; or 3.0% of YE) seven replicates and three pigs per experimental unit. From 50 days to 60 days of age, the animals were fed with only one diet. It was noticed, on the first experiment from 21 to 35 days, that the levels of YE + PL affected (P<0.10) quadratically the DFI and the FW increasing both to a level of 1.91%; DWG and FC were not affected (P>0.10). When comparing the diets containing different levels of YE with the basal diet, it was noticed that the diet containing 2.0% PL + 2.0 YE generated the biggest FW and the diet containing 2.0% PL + 1.0% YE resulted in the worst FC (P<0.10). The height of intestinal villi and the duodenum crypt depth were affected (P<0.10) quadratically by the YE levels obtaining the best levels 1.64 and 1.16% respectively. The ratio villi/crypt increased (P<0.10) linearly with the increase of YE levels. The jejunum morphometry variables were not affected (P>0.10) by the YE levels. There wasn’t any difference (P>0.10) in the duodenum and jejunum morphometries when comparing diets containing YE levels with the basal diet. In the second experiment, from 36 to 49 days of age, none of the performance variables was affected (FW, DWG, DFI, FC) (P>1.0). From 50 days to 60 days of age, the quadratic influence (P<1.0) of the YE on the DFI and DWG was noticed, increasing its levels until the level of 1.67%; however, the effect (P>0.10) of the YE on the FC was not detected. When comparing the diets containing YE with the basal diet, the diet with 1.0% PL + 2.0% YE was the one with the best FC. The conclusion is that the inclusion of 1.91 and 1.67% YE on piglets diets from 21 days to 35 days of age and from 36 days to 49 days of age respectively, allows partially the replacement of 50% of plasma on the diet, which can reduce its inclusions from 4.0 to 2.0% and from 2.0 to 1.0% on the distinct phases. |

No primeiro experimento foram utilizados 120 leitões, dos 21 aos 35 dias de idade, distribuídos em delineamento de blocoscasualizados, com cinco tratamentos (4,0% de PS; 2,0% de PS com 0,0; 1,0; 2,0 ou 3,0% de EL), seis repetições e quatro leitões por unidade experimental. Para avaliações da morfometria do duodeno e jejuno, aos 35 dias de idade um animal por unidade experimental foi abatido. No segundo experimento foram utilizados 105 leitões, dos 36 aos 60 dias de idade. Do desmame (21 dias) aos 35 dias de idade, os leitões foram alimentados com uma dieta única que proporcionou o melhor resultado de desempenho no experimento I. Aos 36 dias de idade, os leitões foram distribuídos em delineamento de blocos casualizados, com cinco tratamentos (2,0% de PS; 1,0% de PS com 0,0; 1,0; 2,0 ou 3,0% de EL), sete repetições e três animais por unidade experimental. Dos 50 aos 60 dias de idade, os animais receberam uma dieta única. No primeiro experimento, dos 21 aos 35 dias de idade, observou-se que os níveis de EL + PS influenciaram (P<0,10) de forma quadrática o CRD e o PF que aumentaram até o nível estimado de 1,91%, GPD e a CA não foram influenciados (P>0,10). Ao comparar as dietas contendo diferentes níveis de EL com a dieta basal, observou-se que a dieta contendo 2,0% de PS + 2,0% de EL proporcionou o maior PF e a dieta contendo 2,0% PS + 1,0% EL proporcionou a pior (P<0,10) CA. A altura de vilosidade e a profundidade de cripta do duodeno foram influenciadas (P<0,10) de forma quadrática pelos níveis de EL, obtendo-se os melhores resultados com os níveis estimados de 1,64 e 1,16%, respectivamente. Os níveis de EL proporcionaram aumento (P<0,10) linear na relação vilo/cripta. Os níveis de EL não alteraram (P>0,10) as variáveis de morfometria do jejuno. Não houve diferença (P>010) na morfometria do duodeno e jejuno ao comparar as dietas contendo níveis de EL com a dieta basal. No segundo experimento, dos 36 aos 49 dias de idade, nenhuma variável de desempenho (PF, GPD, CRD e CA) foi influenciada (P>0,10). Dos 50 aos 60 dias, foi constatada influência quadrática (P<0,10) dos níveis de EL sobre as variáveis CRD e GPD que melhoraram até o nível estimado de 1,67%, porém não houve efeito (P>0,10) dos níveis de EL sobre a CA. Ao comparar as dietas contendo EL com a dieta basal, constatou-se que a dieta com 1,0% PS + 2,0% EL proporcionou a melhor (P<0,10) CA. Conclui-se que a inclusão de 1,91 e 1,67% de extrato de levedura na ração de leitões dos 21 aos 35 e dos 36 aos 49 dias de idade, respectivamente, permite a substituição parcial do plasma nas dietas, podendo reduzir suas inclusões de 4,0 para 2,0% e de 2,0 para 1,0% nas distintas fases.Conselho Nacional de Desenvolvimento Científico e Tecnológicoapplication/pdfporUniversidade Federal de ViçosaMestrado em ZootecniaUFVBRGenética e Melhoramento de Animais Domésticos; Nutrição e Alimentação Animal; Pastagens e ForragiculNucleotídeoPlasmaSuínosDesempenhoMorfometria intestinalNucleotidePlasmaPigsPerformanceIntestine morphometryCNPQ::CIENCIAS AGRARIAS::ZOOTECNIA::NUTRICAO E ALIMENTACAO ANIMALExtrato de levedura em dietas com plasma sanguíneo para leitões dos 21 aos 60 dias de idadeYeast extract on piglets diet at the age of 21 days to 60 daysinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisinfo:eu-repo/semantics/openAccessreponame:LOCUS Repositório Institucional da UFVinstname:Universidade Federal de Viçosa (UFV)instacron:UFVORIGINALtexto completo.pdfapplication/pdf290741https://locus.ufv.br//bitstream/123456789/5687/1/texto%20completo.pdf2cfb5553046b949b1606cc5390be93deMD51TEXTtexto completo.pdf.txttexto completo.pdf.txtExtracted texttext/plain96891https://locus.ufv.br//bitstream/123456789/5687/2/texto%20completo.pdf.txt1c98970ba38f79c2f15593fc286f7405MD52THUMBNAILtexto completo.pdf.jpgtexto completo.pdf.jpgIM Thumbnailimage/jpeg3658https://locus.ufv.br//bitstream/123456789/5687/3/texto%20completo.pdf.jpge7e8721a4a2ad941783b29b27be12719MD53123456789/56872016-04-10 23:15:15.28oai:locus.ufv.br:123456789/5687Repositório InstitucionalPUBhttps://www.locus.ufv.br/oai/requestfabiojreis@ufv.bropendoar:21452016-04-11T02:15:15LOCUS Repositório Institucional da UFV - Universidade Federal de Viçosa (UFV)false |

To evaluate the inclusion of yeast extract (YE), on the diets of the pigs replacing partially the plasma over the performance (FW – final weight, DWG – daily weight gain, DFI – daily food intake and FC – food conversion) and the pigs intestine morphometry at the age of 21 days, two experiments were carried out. In the first experiment, 120 animals were used, from 21 days to 35 days of age, and distributed in experimental randomized block design, constituted by five diets (4.0 % of PL; 2.0 % of PL with 0.0; 1.0; 2.0 or 3.0% of YE) six replicates and four pigs per experimental unit. To evaluate the duodenum and jejunum morphometry, a 35 days old subject was slaughtered per experimental unit. In the second experiment 105 piglets were used, from 21 days to 60 days of age. From the weaning (21 days of age) to 35 days of age, the piglets were fed with a diet that generated the best performance on the first experiment. At the age of 36 days, the piglets were distributed in experimental randomized block design, constituted by five diets (2.0 % of PL; 1.0% of PL with 0.0; 1.0; 2.0; or 3.0% of YE) seven replicates and three pigs per experimental unit. From 50 days to 60 days of age, the animals were fed with only one diet. It was noticed, on the first experiment from 21 to 35 days, that the levels of YE + PL affected (P<0.10) quadratically the DFI and the FW increasing both to a level of 1.91%; DWG and FC were not affected (P>0.10). When comparing the diets containing different levels of YE with the basal diet, it was noticed that the diet containing 2.0% PL + 2.0 YE generated the biggest FW and the diet containing 2.0% PL + 1.0% YE resulted in the worst FC (P<0.10). The height of intestinal villi and the duodenum crypt depth were affected (P<0.10) quadratically by the YE levels obtaining the best levels 1.64 and 1.16% respectively. The ratio villi/crypt increased (P<0.10) linearly with the increase of YE levels. The jejunum morphometry variables were not affected (P>0.10) by the YE levels. There wasn’t any difference (P>0.10) in the duodenum and jejunum morphometries when comparing diets containing YE levels with the basal diet. In the second experiment, from 36 to 49 days of age, none of the performance variables was affected (FW, DWG, DFI, FC) (P>1.0). From 50 days to 60 days of age, the quadratic influence (P<1.0) of the YE on the DFI and DWG was noticed, increasing its levels until the level of 1.67%; however, the effect (P>0.10) of the YE on the FC was not detected. When comparing the diets containing YE with the basal diet, the diet with 1.0% PL + 2.0% YE was the one with the best FC. The conclusion is that the inclusion of 1.91 and 1.67% YE on piglets diets from 21 days to 35 days of age and from 36 days to 49 days of age respectively, allows partially the replacement of 50% of plasma on the diet, which can reduce its inclusions from 4.0 to 2.0% and from 2.0 to 1.0% on the distinct phases. |
