Relação materno-filial da raça Morada Nova recebendo dietas com três níveis de energia, ao final da gestação

Abstract: RESUMO -Objetivou-se com este trabalho avaliar os efeitos de diferentes níveis de energia ofertados no terço final da gestação sobre o comportamento materno-filial de animais da raça Morada Nova. O experimento consistiu de três tratamentos -três grupos de oito matrizes, alimentadas com dietas isoprotéicas contendo diferentes níveis energéticos (2,0; 2,4 e 2,8 Mcal EM/kg MS), com oito repetições cada. Observou-se efeito dos tratamentos sobre as variáveis comportamentais maternas avaliadas (vocalização, ato de c… Show more

“…Moreover, results revealing that MBS was not correlated with the weight of the lamb at birth and the weight of the placenta show that there was apparently no close relationship between the ewe´s nutrition at the end of pregnancy (Clarke, Heasman, Juniper, & Symonds, 1998) and maternalfilial behavior. Mariz et al (2007) found that ewes receiving increased energy intake vocalized and licked more their offspring, but failed to change the lamb´s behavior. This result adds to what was already reported in a recent publication by Asmad et al (2014) that nutrition during pregnancy of sheep has a limited effect on performance of lambs from birth to weaning.…”

“…Several factors may influence maternal behavior (Hernandez, Matthews, Oliver, Bloomfield, & Harding, 2009;Corner et al, 2010), such as previous experience, breed, ewe body condition score, nutritional state, production system and other factors. Since young females may show little or no ability (Mariz et al, 2007;Dwyer, 2008;Dwyer, 2014), they reduce lamb viability without human interference. Fear-caused reaction by female sheep was greater in young animals than in older ones (Silveira, Fischer, & Mendonça, 2010).…”

“…A manutenção do comportamento materno é facilitada pela ação hormonal (estradiol, prolactina, ocitocina e opióides) e sensorial (audição, olfato e visão) (MARIZ et al, 2007). O olfato é extensivamente usado em muitos aspectos maternais em mamíferos, assegurando a coordenação das interações materno-filiais.…”
