“…Fatty acid toxicity in rumen microorganisms is reduced when animals feed mainly on roughage (more than 80% roughage) because of the association of fatty acids with hydrophobic surfaces on forage particles (Moreira et al 2014). Notably, the lipid profile of licuri oil is richer in saturated fatty acids than are the majority of vegetable sources, thus reducing its toxicity to microorganisms.…”

(1 of licuri oil in concentrated dry matter. The intakes of dry matter, crude protein and non-fiber carbohydrate levels were not affected by the addition of licuri oil; however, the intake of neutral detergent fiber and total digestible nutrients decreased linearly. Neutral detergent fiber digestibility was reduced linearly with increasing levels of licuri oil in the concentrate. There were no changes in blood glucose levels, but blood urea nitrogen levels varied according to the time of the day when the blood was collected. Inclusion of licuri oil at 45.0 g kg (1 in feed concentrates results in improved dry matter and ether extract digestibility.

“…Studies aimed at characterizing the ruminal metabolism of these byproducts are needed to identify potential byproducts that could be used efficiently in the diet of ruminants to replace conventional ingredients (Cruz et al, 2014;Hulshof et al, 2012;Moreira et al, 2014;Silva et al, 2014). Among these byproducts, glycerin, which is obtained in the transesterification process from oil to biodiesel in the crude form, is an alternative (Cruz et al, 2014;Farias et al, 2012;Martínez-Fernández et al, 2014).…”

ABSTRACT. This study was realized to evaluate the production of gas and volatile fatty acids when glycerin was used to replace four forage species through the use of a semi-automated technique in vitro. The experimental design included 4 treatments and 4 replications. The treatments consisted of increasing levels of glycerin (0, 30, 50 and 70%), which was used to replace the forage plants Elephant grass, sugar cane silage, corn silage and Brachiaria grass. Replacement of the Brachiaria and Elephant grasses with glycerin linearly reduced the production of methane and carbon dioxide and ammonia nitrogen and had a positive effect on forage quality (p < 0.05). With the addition of glycerin, the values for acetate concentration decreased (p < 0.05); however, when added glycerin there was increased in propionic and butyric acid concentration (p < 0.05). Substitution of forage species for glycerin by tests for semi-automatic technique in vitro reduce the production of greenhouse gases (CH 4 and CO 2 ) which reduction in energy loss, and increase volatile fatty acids propionic and butyric.Keywords: acetate, butyrate, N-NH 3 , propionate, VFAs.Degradação e produção de gases in vitro de glicerina da cadeia produtiva do biodiesel RESUMO. Este estudo foi realizado para avaliar a produção de gás e ácidos graxos voláteis da glicerina em substituição à quatro espécies forrageiras pela técnica semi-automática in vitro. O delineamento experimental incluiu 4 tratamentos e 4 repetições. Os tratamentos consistiram em níveis crescentes de glicerina (0, 30, 50 e 70%), em substituição às forrageiras capim Elefante, cana-de-açúcar, silagem de milho e Braquiária. A substituição das gramíneas forrageiras capim Brachiaria e capim Elefante pela glicerina afetou a produção de metano, dióxido de carbono e nitrogênio amoniacal e teve um efeito positivo sobre a qualidade da forragem (p < 0,05). Com a adição de glicerina, os valores da concentração de acetato reduziram (p < 0,05). Todavia, a adição de glicerina aumentou as concentrações de ácido propiônico e butírico (p < 0,05). A substituição de espécies forrageira pela glicerina através da técnica semiautomática in vitro reduz a produção de gases de efeito estufa (CH 4 e CO 2 ) que diminuirá a perda de energia e eleva os ácidos graxos voláteis propiônico e butírico.Palavras-chave: acetato, butirato, N-NH 3 , propionato, AGVs.

“…The gases and volatile fatty acids (VFAs) production derived from rumen fermentation depende on the feed characteristics, the intake and digestibility of the feed by animal (Moreira et al, 2014;Oliveira et al, 2015). Thus, there is the possibility that gas mitigation could be accomplished by modifying the rumen fermentation through changes of diet and thus manipulating the microbiota of the rumen with feed additives or components naturally present in oilseed press cake Silva et al, 2016).…”

ABSTRACT. This study aimed to evaluate the production of methane, carbon dioxide, and volatile fatty acids and changes in ruminal pH in vitro with oilseed press cakes inclusion, such as, cottonseed, sunflower, castor bean, moringa and jatropha at four different levels (0, 30, 50 and 70%) in replacement to the sugarcane in ruminant feeding using semi-automated in vitro technique. The byproduct that produced less CO 2 was cottonseed cake (p = 0.0059). The cakes that produced the least amount of CH 4 were moringa at 70% (p < 0.05) and cottonseed at 70% levels (p < 0.0001). The cakes that had the highest increases in VFAs were cottonseed and castor (p < 0.0001). Additionally, greater pH was moringa at 70% and cottonseed at 50% levels (p < 0.0001). The greater acetate concentration was 70% cottonseed cake, propionate concentration with 30% cottonseed and butyrate concentration with 50% moringa in sugarcane replace. At the 70% level, the moringa cake displayed the highest decreases in methane production and reduction in energy loss. At the 50% substitution level, the cottonseed cake is the most suitable replacement for sugarcane in order to reduce the production of greenhouse gases.Keywords: acetate, butyrate, N-NH 3 , propionate, VFAs.Efeito da substituição de cana-de-açúcar por tortas oleaginosas sobre a produção in vitro de gases do efeito estufa e ácidos graxos voláteis RESUMO. Objetivou-se avaliar a produção de metano, dióxido de carbono, ácidos graxos voláteis e mudanças no pH ruminal in vitro com tortas de oleaginosas: algodão, girassol, mamona, moringa e pinhão manso incluídas em quatro níveis diferentes (0, 30, 50 e 70%) em substituição à cana-de-açúcar na dieta de ruminantes, utilizando-se a técnica semiautomática in vitro. O subproduto que produziu menos CO 2 foi o algodão (p = 0,0059). As tortas de oleaginosas que produziram menos CH 4 foram moringa (p < 0,05) e algodão (p < 0,0001) a 70% de inclusão. As tortas que aumentaram a produção de AGVs foram algodão e mamona (p < 0,0001). Além disso, o pH aumentou nos níveis de inclusão a 70% de moringa e 50% de algodão (p < 0,0001). A maior concentração de acetato ocorreu na torta de algodão a 70%, já o propionato na torta de algodão à 30% e a maior concentração de butirato na torta de moringa à 50% em substituição à cana-de-açúcar. Em nível de 70%, a torta de moringa apresentou maior redução no metano e na energia alimentar. Em nível de substituição de 50%, a torta de algodão foi a substituição mais adequada para a canade-açúcar, a fim de reduzir a produção de gases com efeito de estufa.Palavras-chave: acetato, butyrato, NH 3 , propionato, AGVs.
