“…The equations generated to predict values showed that every additional 1% glycerin in the diet would generate an 8.37 and 7.45 kcal kcal −1 difference in DE and ME (as-fed basis), respectively; this would mean a 126 and 112 kcal increase in the diets containing 15% glycerin. These results reinforce the expressive energy potential of glycerin in pig diets and that it can be characterized as an energy feedstuff alternative to conventional ingredients, as reported by Gomide et al (2012).

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.

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.

“…O mesmo foi observado por Gomide et al (2012), que encontraram menor perda de líquido por descongelamento ao utilizar níveis crescentes de até 160g/kg de glicerina bruta para suínos em terminação. A análise estatística revelou interação entre os diferentes níveis de glicerina e sexo para o teor de cinzas no pernil dos suínos, mostrando comportamento diferenciado em relação ao sexo, com efeito quadrático para machos castrados, que mostraram um maior teor de cinzas no nível de 156,67g/kg de glicerina na alimentação (Fig.…”

Universidade Federal de Lavras  Lavras, MG  RESUMO O objetivo deste trabalho foi avaliar os efeitos do fornecimento de diferentes níveis de glicerina na alimentação sobre a qualidade da carne de suínos em terminação. Foram utilizados 30 machos castrados e 30 fêmeas que apresentaram peso inicial de 79,3±4,0kg. Utilizou-se delineamento em blocos casualizados (peso inicial) em esquema fatorial 2 × 4 + 2, sendo duas categorias sexuais (macho castrado e fêmea), quatro níveis de glicerina bruta (50, 100, 150 e 200g/kg) e dois grupos controle (macho castrado e fêmea alimentados com dieta sem glicerina), totalizando dez tratamentos com seis repetições e a unidade experimental representada por um animal. Após o abate, foram realizadas as análises físico-químicas e centesimais dos músculos Longissimus dorsi (lombo) e Semimembranosus (pernil) do lado esquerdo das carcaças. Os resultados mostraram interação entre os níveis de glicerina e sexo para a intensidade de vermelho e cinzas no pernil. Observou-se que, nos corte do lombo, o pH final dos machos castrados foi maior do que o das fêmeas suínas. Os resultados indicaram que suínos machos castrados apresentaram maior teor de extrato etéreo no pernil e no lombo quando comparados às fêmeas. No pernil, o teor de cinzas das fêmeas suínas foi superior ao dos machos castrados. Entretanto, no lombo, não se verificou influência dos níveis de glicerina sobre a composição centesimal. Contudo, apesar de o uso da glicerina ter ocasionado modificação na cor vermelha e teor de cinzas no pernil de machos castrados, de forma geral não provocou mudanças relevantes sobre as características físico-químicas e centesimais da carne de suínos, podendo ser utilizada até o nível de 200g/kg na alimentação desses animais. (50, 100, 150 and 200g/kg) Palavras-chaves: biocombustível, composição centesimal, composição físico-química ABSTRACT The objective of this study was to evaluate the effects of providing different levels of glycerin in the diet on meat quality of finishing pigs. 30 barrow and 30 female pigs were used, with initial weight of 79.3±4.0kg. A randomized block design was used (initial weight) in a factorial 2 x 4 + 2, being two sex categories (barrow and female), four levels of crude glycerin

“…Similar results were found by Gallego et al (2014), who studied neutralized semi-purified glycerin at the levels of 0, 3.5, 7, 10.5, and 14% and did not observe an influence on performance parameters. Gomide et al (2012) did not observe an effect of substitution of corn in finishing pig diets for crude glycerin at the levels of 0, 4, 8, 12, and 16% on any of the analyzed performance traits. Similar results were reported by Berenchtein et al (2010).…”

“…Biodiesel has the great advantage of being produced from renewable sources, such as oilseeds, mirrored by the enormous growth of its production and consequent supply of the byproduct glycerin, which was 69 m 3 in 2005 and rose to 3,419,838 m 3 in 2014 (ANP, 2015). The main component of glycerin, glycerol, is a highenergy compound present in feedstuffs and in the animal metabolism that has the potential to be used as a partial substitute for cereal grains or other high-starch ingredients in pig diets (Berenchtein et al, 2010;Gallego et al, 2014;Gomide et al, 2012); however, a consensus has not been reached as to its inclusion level in diets. Berenchtein et al (2010) reported that purified glycerin can be used at levels up to 9% in the diet, whereas Huepa et al (2015) asserted it is possible to include up to 12% without impairing the performance of finishing animals.…”

-The objective of this study was to evaluate performance and carcass and meat characteristics of finishing pigs fed diets with different levels of glycerin, while maintaining the electrolyte balance. Forty barrows with an initial weight of 97.76±13.44 kg were distributed, in a randomized block design, into four treatments with five replicates. Treatments consisted of diets containing 0, 5, 10, and 15% glycerin. Inclusions of salt and sodium bicarbonate were adjusted to balance the sodium content and maintain the same electrolyte balance of the diets as a function of glycerin inclusions. In vivo backfat thickness, daily feed intake, daily weight gain, and feed conversion were measured. After the animals were slaughtered, pH and temperature were measured 45 min and 24 h postmortem, and backfat thickness, loin-eye area, drip loss, and colorimetry were determined. Glycerin inclusion levels did not influence the performance of barrows. Hot carcass weight, dressing percentage, and lightness had higher values when pigs were fed diets containing 2.32, 2.43, and 2.61% glycerin, respectively. The other carcass and meat characteristics were not influenced. Glycerin can be used in finishing pig diets without compromising results of performance or carcass and meat characteristics up to the inclusion level of 15%.
