“…The reaction is catalyzed by an acid or a base, using sodium hydroxide or potassium hydroxide (OLIVEIRA et al, 2013). In this reaction, the main molecules of oils and fat, named triacylglycerols, are separated into fatty acids and glycerin (LARSEN, 2009).…”

The aim of this study was to evaluate the effects of vegetable glycerin on performance and egg quality of red-egg layers in the second production cycle. A total of 252 Hy-Line Brown layers weighing 1.919 ± 0.095 kg, at 90 weeks, were used in a completely randomized design with six treatments and seven birds per replication. The experiment lasted 84 days. Treatments consisted of a control diet (no glycerin) and five diets with increasing levels of vegetable glycerin (2, 4, 6, 8, and 10%). The following variables were evaluated: feed intake (g/bird/day); egg production (%); egg weight (g); egg mass (g/bird/day); conversion per egg mass (kg kg) and per dozen eggs (kg/dz); percentages of albumen, yolk, and shell; eggshell thickness (mm); and egg specific gravity. (Y = 67.69 + 54.23X, R 2 = 0.78) and egg mass (Y = 44.84 + 42.87X, R 2 = 0.66) improved linearly with the glycerin levels. A quadratic effect was observed (Y = 114.11 + 336.96 X -3,169.6 X 2 , R 2 = 0.52) on feed intake. In conclusion, glycerin can be used to partially replace corn in diets for layers in the second production cycle at inclusion levels of up to 10%. Key words: Alternative feedstuff. Nutrition.

Foram utilizadas 252 poedeiras Hy-Line Brown, pesando 1,919 ± 0,095 kg com 90 semanas, em um delineamento inteiramente casualizado com seis tratamentos e sete aves por repetições. O experimento teve duração de 84 dias. Os tratamentos consistiram em uma dieta controle (sem glicerina), e cinco dietas com níveis de glicerina vegetal (2, 4, 6, 8 e 10%). As variáveis avaliadas foram: consumo de ração (g/ave/dia), produção de ovos (%), peso do ovo (g), massa de ovos (g/ave/dia), conversão por massa de ovos (kg/kg), conversão por dúzia de ovos (kg/dz), percentual de albúmen, gema e casca, espessura de casca (mm) e gravidade específica dos ovos. A produção (Y = 67.69 + 54.23X, R 2 = 0.78) e massa de ovos (Y = 44.84 + 42.87X, R 2 = 0.66) melhoraram linearmente com os níveis de glicerina. Foi observado efeito quadrático (Y = 114.11 + 336.96 X -3.169.6 X 2 , R 2 = 0.52) sobre o consumo de ração. Conclui-se que a glicerina pode ser utilizada em substituição parcial ao milho, nas dietas para poedeiras em segundo ciclo de produção, no nível de até 10% de inclusão.

“…Moreover, the antinutritional factors of ricin are able to bind to the ribosomes, stopping intracellular protein synthesis and causing cell death (Oliveira, Antoniassi, Freitas, & Muller, 2013), making it highly detrimental to rumen microorganisms and explaining the reduction in gas production.…”

ABSTRACT. This study aimed to evaluate the in vitro degradability and gas production in diets containing byproducts from the national biodiesel industry (castor bean, canola, forage radish and black sunflower) replacing Brachiaria grass in four levels (0, 30, 50 and 70%). The inoculum for in vitro incubation was obtained from three fistulated Holstein cows. The experimental design was 4 x 4 factorial completely randomized experimental design consisting of four byproducts and four levels. All byproducts studied had a significant effect (p < 0.05) on in vitro digestibility. The castor bean byproducts promoted the lowest cumulative gas production at the end of 48 hours incubation. Regarding digestibility, the byproducts of canola and radish at 70% level did not affect the degradability of dry matter.

“…As stated by Oliveira et al (2013), considering the total biodiesel produced in the plants, 33.2% were generated in those using soybean oil exclusively; 36.8% in plants that employ soybean trivial task, though, mainly in some laboratories. Furthermore, the incomplete recovery of this marker in the feces has significantly influenced the precision of results obtained with this method (RIBEIRO FILHO et al, 2008).…”

Glycerin is a by-product from the biodiesel chain whose energy value can be beneficial to pig diets. In this study, eight barrows were distributed individually into metabolic cages in a completely randomized block design. The animals were fed diets containing 0, 5, 10 and 15% glycerin from soybean oil and subjected to the methods of total feces and urine collection and chromic oxide marker. We determined the digestibility coefficients (DC); the dietary levels of digestible dry matter (DM), organic matter (OM), crude protein (CP), mineral matter (MM), ether extract (EE), an neutral detergent fiber (NDF); digestible energy (DE); metabolizable energy (ME); and these last two variables corrected for the nitrogen content (DEn and MEn). Digestible OM values increased linearly with glycerin inclusion in the diets. The digestible CP of the diets showed an inversely proportional relationship with glycerin inclusion levels. Digestible MM decreased linearly when determined by the total collection method and quadratically when determined by the marker method. There was a linear increase in the digestible and metabolizable coefficients of energy, DE, DEn, ME and MEn of the diets as the glycerin inclusion level was increased. Inclusion of up to 15% glycerin obtained from soybean oil production increased the digestible fractions of organic matter and energy of the diets. Key words: Biodiesel. Digestibility. Glycerol. Marker. Metabolizability. Total feces collection. ResumoA glicerina é um coproduto oriundo da cadeia do biodiesel que possui valor energético capaz de contribuir favoravelmente em dietas para suínos. Neste estudo, foram utilizados oito suínos machos castrados, distribuídos individualmente em gaiolas de metabolismo em delineamento experimental de blocos ao acaso. Os animais foram alimentados com dietas contendo 0, 5, 10 e 15% de glicerina oriunda do óleo de soja, submetidos ao método de coleta total de fezes e urina e o indicador óxido crômico. Foram determinados os coeficientes de digestibilidade (CD); e níveis dietéticos digestíveis de matéria seca (MS), matéria orgânica (MO), proteína bruta (PB), matéria mineral (MM), extrato etéreo (EE) e and tallow; and 9.1% in units that use the soybean and cottonseed oils.
