Resumo: The effect of oestradiol benzoate (OB) on mortality rate and performance of a sample of 706 newborn Large White x Landrace piglets from 62 litters. After being individually weighed, they were divided into 3 treatments: T0, T1 and T2. T0 piglets weighing less than 1.200g were administered commercial drug (0.1mg OB, 0.1ml ethanol, 2.5mg chlorobuthanol diluted 0.9ml vegetal oil). T1 piglets weighing less than 1.200g also received similar commercial drug, with the exclusion of OB. T2 group weighing over, 1.200g received no treatment. Each litter was considered a replicate. Mortality rates for T0 and T1 were respectively 25.82% and 25.45%, while 5.62% for T2 showed to be significantly different (P≤0.05). Mortality rate was not influenced by OB administration, but only by the weight at birth. The weight gain from birth to 21-day age was different (P≤0.05) between T0 (4,199.6g), T1 (4,045.1g) and T2 (3,958.9g), but showed no significant difference between the treatments for weight at 21-day age.

Os leitões, ao nascimento, foram individualmente pesados e divididos em 3 tratamentos: T0 - leitões com peso inferior a 1.200g, tratados com uma composição comercial* (0,1mg de BE, 0,1ml de etanol, 2,5mg de clorobutanol, suspensos em 0,9ml de óleo vegetal); T1 - leitões com peso inferior a 1.200g, tratados com 1ml do veículo (mesma fórmula de T0, sem BE), T2 - leitões com peso superior a 1.200g, sem qualquer tratamento. Considerou-se cada leitegada como uma repetição. A taxa de mortalidade para os leitões do T0 e T1 foi, respectivamente, 25,82% e 25,45%, sendo diferente (P≤0,05) do valor dos leitões de T2, igual a 5,62%. A taxa de mortalidade não foi melhorada pelo BE, mas foi influenciada pelo peso ao nascer. Houve diferença (P≤0,05) para o ganho de peso do nascimento até os 21 dias de idade para os leitões do tratamento T0 em relação aos do T1 e T2, respectivamente, 4.199,6g, 4.045,1g e 3.958,9g. Não houve diferença no peso aos 21dias de idade entre os animais dos tratamentos.Editora da Universidade Estadual de Maringá2008-07-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.uem.br/ojs/index.php/ActaSciAnimSci/article/view/440810.4025/actascianimsci.v20i0.4408Acta Scientiarum.
