“…The dietary BP inclusion led to a significantly lower SFA content (p < .001) in the hind leg meat, mainly due to a reduction in the contents of C14:0, (p < .001), C15:0 (p < .001), C16:0 (p < .001) and C17:0 (p ¼ .014). Branched chain fatty acids (BCFA) are indicative of the rabbit peculiar digestive system, which allows the recycling of large amounts of caecal microorganisms, and consequently microbial FA, via caecotrophy (Papadomichelakis et al 2010b). The total BCFA amount was significantly affected (p ¼ .014) by BP inclusion in the diet, with lower values recorded in the BP15 group if compared to the other groups.…”

The aim of the present study was to evaluate the effects of dietary bilberry pomace (BP) on colour, cooking losses, proximate composition and fatty acid (FA) profile of hind leg meat in growing rabbits. One hundred and forty-four Grimaud weaned rabbits (35 days old) were randomly divided into four groups of 36 animals each and fed ad libitum with a basal diet (C diet) tested against three assay diets developed by substituting 50, 100 and 150 g/kg of the C diet with BP (BP5, BP10 and BP15 diets, respectively). At 83 days of age, the rabbits were slaughtered without fasting. Inclusion of BP in the diet did not significantly affect colour, cooking losses, ash and protein contents, but determined a significant increase of ether extract in the muscle. Increasing dietary inclusion of BP also determined a proportional increase of total polyunsaturated fatty acids (PUFA) and total n-3 FA, as well as a proportional decrease of total saturated fatty acids (SFA), total branched chain fatty acids (BCFA) and total monounsaturated fatty acids (MUFA) in the muscle. Dietary BP significantly improved the PUFA/SFA ratio, the R n-6/R n-3 FA ratio and the atherogenicity, thrombogenicity and hypocholesterolemic/hypercholesterolemic FA indexes of rabbit meat but it decreased D5-desaturase plus D6-desaturase index. The obtained results suggest that BP inclusion in growing rabbit diets can improve the fatty acid profile of hind leg meat, with consequent health benefits to consumers. ARTICLE HISTORY

“…Four diets, described in detail previously (Papadomichelakis et al., 2010), were used in this work. The diets had either a low‐ or a high‐digestible fibre (DF, hemicellulose and pectin) content [LDF: 180 vs. HDF: 260 g/kg dry matter (DM)], approximately estimated fromtables (Gidenne, 2003) and were supplemented with SO (20 g/kg) or not for each case.…”

The study aimed to describe the interactions between nutrition and caecal bacteria abundance using odd-numbered and branched-chain fatty acids (OBCFA). Following a 2 × 2 factorial design, 47 rabbits were fed diets with two levels of digestible fibre (DF, 180 vs. 260 g/kg DM) supplemented with soybean oil (SO, 20 g/kg) or not. At 77 days of age, fatty acid (FA) composition was determined in caecal contents. The microbial origin of OBCFA vs. dietary FA in caecal contents was illustrated by clustering of these FA in the loading plots of principal component analysis. The contribution of odd-numbered FA in the OBCFA pattern was increased (p < 0.05) for high DF diets, whereas that of branched-chain FA decreased (p < 0.05), indicating potential shifts in the relative abundance of Gram-negative and Gram-positive fibrolytic bacteria respectively. Soybean oil reduced the relative importance of OBCFA (p < 0.001) in total microbial FA; however, its effects appeared to depend on the readily available fermentable substrate, as indicated by the DF × SO interactions (p < 0.001). In conclusion, OBCFA may be potentially used as markers of caecum function, but further detailed studies are necessary to validate their use as diagnostic tools in rabbit nutrition.

“…Isso se deve ao seu potencial de gerar produtos com diferentes funções e alto valor biológico, devido ao alto teor de proteína e óleo presente nos grãos (ALBRECHT et al, 2008). Os produtos originados, como o farelo de soja, podem ser utilizados na alimentação animal (PAPADOMICHELAKIS et al, 2010), o óleo (CELLA et al, 2002) e a carne de soja (TAKAHASHI; TAKAHASHI, 2008) na alimentação humana, e também como matéria prima para produção de biocombustíveis (SUAREZ et al, 2009).…”

A sustentabilidade da produção de soja (Glycine max (L.) Merrill.) deve obrigatoriamente considerar a utilização de insumos alternativos, que reduzam o custo de produção e sejam sustentáveis do ponto de vista ambiental. Sendo assim, o objetivo do trabalho foi comparar duas formulações de adubação organomineral com adubação mineral, em três cultivares de soja. Objetivou-se também determinar a melhor dose de adubação organomineral para três cultivares de soja. Foram realizados dois experimentos distintos, ambos utilizando três cultivares de soja, de grupo de maturação distinto, submetidas a tipos de adubos (experimento 1) e a doses de adubo organomineral (experimento 2). Os experimentos foram realizados em blocos ao acaso com quatro repetições, sendo avaliados, massa seca de plantas, número de nódulos e componentes de produtividade da soja. O organomineral SQ/CP possui resposta intermediária em relação à adubação mineral, não diferindo do organomineral JN1, sendo superior a testemunha. No primeiro experimento não se observou interação entre adubos e cultivares para produtividade. O fertilizante mineral não diferiu do organomineral JN1, sendo ambos superiores à testemunha. No segundo experimento houve interação entre as doses e cultivares para a variável produtividade, em que a cultivar Nidera 7321 respondeu a até duas vezes a recomendação do organomineral SQ/CP.
