Resumo: | The purpose of this experiment was to study the effects of years and periods of the year on weight and size of Landrace litters. A factorial 3 x 2 (years and periods of year) was studied according to a completely randomized design with 40 replications per treatment. Simple correlations were studied in 102 litters at three ages. Statistical differences were observed between years and periods of the year in same analysis. Weight and size of litters at birth and 21 days of age were greater during the dry-cold period. Weight gain of litters until 21 days of age was statistically different between years and periods of the year. However, better weight gain was observed during dry-cold period. Simple correlations between weights, between sizes and between weight and sues were positive and significant but correlations between birth weight and 21 days of age were not significant. |

Foi utilizado um delineamento inteiramente casualizado com seis tratamentos, num esquema fatorial 3 x 2, com os fatores anos e períodos do ano, com 40 repetições. Correlações simples foram estudadas em 102 leitegadas, em três idades. Observou-se que os anos e períodos do ano apresentaram diferenças estatísticas para algumas análises. O período seco-frio registrou maiores médias para peso e tamanho de leitegadas ao nascer e aos 21 dias de idade. O ganho de peso das leitegadas até a idade de 21 dias foi estatisticamente diferente entre os anos e períodos do ano; no entanto, o período seco-frio apresentou melhor média. As correlações simples em três idades entre os pesos, entre os tamanhos e entre os pesos e tamanhos foram positivos e significativas, exceto entre o peso ao nascer e aos 21 dias de idade.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraLui, Jeffrey FredericoBarbosa, José CarlosCarregal, Ronaldo DessimoniGiannoni, Marcos Antonio2014-04-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/16341Pesquisa Agropecuaria Brasileira; v.17, n.10, out. 1982; 1529-1534Pesquisa Agropecuária Brasileira; v.17, n.10, out. 1982; 1529-15341678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/16341/10567info:eu-repo/semantics/openAccess2014-04-15T19:48:12Zoai:ojs.seer.sct.embrapa.br:article/16341Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-15T19:48:12Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
