Efeito do tamanho da leitegada sobre a variação dos pesos ao nascer e ao desmame em leitões da raça landrace

Abstract

Objetivou-se avaliar o efeito da classe de tamanho de leitegada ao nascer sobre a variação do peso ao nascer e ao desmame e sobre a taxa de sobrevivência dos leitões do nascimento ao desmame. Para isso usou-se informações de peso individual ao nascer e ao desmame de leitões de um banco de dados de 295 leitegadas de suínos da raça Landrace, nascidos entre 2000 e 2010, em uma granja de suínos do oeste do estado do Paraná. As leitegadas foram classificadas pelo número total de leitões nascidos em pequenas (até 7 leitões), médias (8 a 13 leitões) e grandes (14 e mais leitões). Os dados foram analisados considerando-se os efeitos de ano de acasalamento das porcas e classe de tamanho de leitegada ao nascer. Correlações entre as características de peso médio e variância do peso e tamanho da leitegada foram maiores nas leitegadas médias e grandes. Classe de tamanho da leitegada influenciou significativamente peso médio ao nascer e ao desmame dos leitões e variância do peso ao nascer. Leitões de leitegadas médias e grandes pesaram menos, apresentaram maior variação do peso ao nascer e menor taxa de sobrevivência até o desmame do que leitões de leitegadas pequenas.
