Abstract(s)
A tradição na criação e no consumo de carne de coelho na União Europeia,
especialmente em países como Portugal, vem enfrentando desafios devido ao
aumento dos custos de produção, o que resultou em preços mais elevados para
os consumidores. Em resposta a esta situação, procuraram-se alternativas mais
sustentáveis visando minimizar os impactos ambientais e que reduzam os custos
produtivos. Neste contexto, este estudo investigou o potencial da suplementação
de folhas de oliveira, um subproduto muito abundante na indústria de azeite em
Portugal, na promoção da saúde intestinal de coelhos recém desmamados. A
abordagem experimental adotada foi a divisão de 30 coelhos em 4 grupos de
tratamento suplementado com folha de oliveira com ou sem selénio e, um grupo
controle. Embora as dietas implementadas não tenham tido impacto significativo
na taxa de crescimento específico dos diferentes lotes, os resultados
demonstraram que a suplementação com folha de oliveira promoveu
modificações na arquitetura do ceco nomeadamente com o aumento da
profundidade das criptas e com o aumento na quantidade de células M. Estes
resultados destacam o potencial da suplementação de folhas de oliveira como
uma estratégia benéfica para a saúde intestinal e possivelmente imunológica dos
coelhos. Além disso, o estudo ressalta a importância da suplementação com
selénio uma vez que os animais suplementados não demonstraram tantas
erupções cutâneas como os animais que não foram tratados com selénio
aquando, acometidos por uma dermatofitose. Esses resultados fornecem
informações de grande importância para a indústria da cunicultura e apontam
para possíveis direções em pesquisas futuras na área da nutrição desta espécie.
The tradition of breeding and consuming rabbit meat in the European Union, especially in countries such as Portugal, has been facing challenges due to rising production costs, which resulted in higher prices for consumers. In response to this situation, more sustainable alternatives have been sought to minimize environmental impacts and reduce production costs. In this context, this study investigated the potential of olive leaf supplementation, a abundant by-product in the olive oil industry Portugal’s, in promoting the gut health of newly weaned rabbits. The experimental approach adopted was the division of 30 rabbits into treatment 4 groups supplemented with olive leaf with or without selenium and a control group. Although the implemented diets did not have a significant impact on the specific growth rate of the different lots, the results showed that the supplementation with olive leaf promoted changes in the architecture of the cecum, namely with the increase in the depth of the crypts and in the amount of M cells. These findings highlight the potential of olive leaf supplementation as a beneficial strategy for the gut and possibly immune health of rabbits. In addition, the study emphasizes the importance of selenium supplementation since the supplemented animals did not show as many rashes as the animals that were not supplemented when they were affected by a dermatophytosis. These results provide information of great importance for the rabbit breeding industry and point to possible directions in future research in this species nutrition.
