Effect of replacement of sugarcane by oilseed press cakes in greenhouse gases and volatile fatty acids production in vitro. Repositório Alice
MOREIRA, M. N.; SILVA, A. M. de A.; BEZERRA, L. R.; CARNEIRO, H.; MORAIS, R. K. de O.; MEDEIROS, F. F. de.
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 CO2 was cottonseed cake (p = 0.0059). The cakes that produced the least amount of CH4 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...

In vitro degradation and gas production of glycerin generated in the biodiesel production chain. Repositório Alice
SILVA, L. S.; BEZERRA, L. R.; SILVA, A. M. de A.; CARNEIRO, H.; MOREIRA, M. N.; OLIVEIRA, R. L..
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...
