Resumo: | In order to evaluate the reproductive performance of sows under different alimentar regimens, 48 Large White gilts were utilized. They were subjected to four different rations during three consecutive reproductive cicle. These rations consisted of 2; 1.8; 1.6 and 1.4 kg of food per day, during gestation and "ad libitum" during lactation. During the gestation period, the sows were kept confined in groups of six per pen and they received the feed through individual feeders. Piglets wore weaned with 35 days of age. Each increase of feed consumption in the gestation period resulted in a linear increase in the weight gain of the sows (P<0,001). The weight of sows during lactation decreased linearly (P<0,01) with the increased consumption of feed during gestation. Biggest litters were observed in the second and third reproductive cicle. Nevertheless, no differences were observed among treatments in regard to the number of alive and death born piglets. Litters from sows kept under 2 kg of feed per day showed more weighty litters at birth and at the weaning period than those kept under 1.6 kg of feed. Mortality rate was higher among piglets from the third reproductive cicle than that from the second and first ones. Nevertheless, mortality rate was similar among litters from all treatments. |

Durante a gestação, as porcas permaneceram confinadas em grupos de seis por baia e receberam ração em bretes individuais, uma vez ao dia. O desmame dos leitões foi realizado aos 35 dias de idade. A cada aumento do nível de consumo de alimento na gestação resultou um aumento linear (P<0,001) no ganho em peso da porca. O peso durante a lactação decresceu linearmente (P<0,01) com o aumento de consumo na gestação. As porcas produziram leitegadas maiores na segunda e terceira parição, mas o número de leitões nascidos vivos ou mortos não foi diferente entre os tratamentos. O nível de 2 kg/dia proporcionou leitegadas mais pesadas (P<0,05) ao nascer e ao desmame em relação ao nível de 1,6 kg/dia.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraCosta, ValdomiroFerreira, Aloízio SoaresGomes, Paulo CezarFialho, Elias TadeuFreitas, Alfredo Ribeiro de2014-04-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/15950Pesquisa Agropecuaria Brasileira; v.17, n.6, jun. 1982; 933-940Pesquisa Agropecuária Brasileira; v.17, n.6, jun. 1982; 933-9401678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/15950/10066info:eu-repo/semantics/openAccess2014-04-16T13:42:02Zoai:ojs.seer.sct.embrapa.br:article/15950Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-16T13:42:02Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
