“…Oliveira et al (11) não observaram diferenças nas medidas de morfometrias no intestino delgado de leitões que receberam dietas com níveis de 9% e 18% de glicerina bruta. Contudo, observaram aumento do número de células secretoras de IgA no jejuno ao adicionarem 9% de glicerina bruta; diferenças na expressão de RNAm com o aumento de 9% e 18% de glicerina bruta no jejuno e íleo e redução das células caliciformes no íleo.…”

“…Com a finalidade de reduzir o custo das dietas de suínos, sobretudo o custo energético, a glicerina bruta passou a ser incluída nas rações de leitões na fase de creche (7) . Por tratar-se de um produto de sabor adocicado, com boa palatabilidade e alta digestibilidade (5,(8)(9) , podendo substituir em parte cereais (5) , como também a lactose e o soro de leite em pó (2,(10)(11) , ingredientes tradicionalmente incluídos nas dietas de pós-desmame como fontes energéticas de alta digestibilidade, é um ingrediente alternativo que poderá facilitar a transição da dieta líquida (leite da porca) para a dieta sólida. O período pós-desmama é marcado pelo consumo reduzido de alimento, mobilização de reserva energética do leitão e alterações na mucosa intestinal, que ocorrem em função da mudança da dieta, reduzindo a capacidade de digerir e absorver os nutrientes (12) .…”

ResumoObjetivou-se avaliar a inclusão de glicerina bruta para leitões na fase de creche. No ensaio de desempenho, foram usados 80 animais machos, castrados, com peso inicial de 6,64 ± 0,8 kg. O delineamento foi de blocos ao acaso e os tratamentos consistiram em 0%; 2%; 4% e 6% de glicerina bruta. Houve efeito quadrático para peso final, ganho médio diário e consumo de ração, a máxima inclusão de glicerina bruta foi de 2,77% para maior consumo diário. Para o GMD, o nível de 2,76% de glicerina bruta possibilitou o melhor ganho e peso final; contudo, sem efeito na conversão alimentar. Houve diferença sobre a incidência de diarréia (p=0,014), quando se incluiu 2% de glicerina bruta na dieta. Houve efeito linear decrescente na porcentagem do TGI (p=0,006), intestino delgado (p=0,038), rins (p=0,089) e fígado (p=0,037) dos leitões que não receberam glicerina bruta na ração. Observou-se efeito quadrático no peso relativo do baço e do pâncreas dos leitões, o nível de 2,73% de glicerina bruta resulta em menor peso de pâncreas e 3,04% de glicerina aumentou o peso do baço. O nível de 2,76% de glicerina bruta promove o maior ganho de peso para leitões na fase de creche. Palavras-chave: desempenho; digestibilidade; glicerol; suíno. AbstractThis study evaluated the inclusion of crude glycerin for piglets in the starter phase. In the performance assay, we used 80 barrows, with initial weight of 6.64 ± 0.8 kg. The experimental design was of randomized blocks and the treatments consisted in 0%, 2%, 4% and 6% of crude glycerin. There was a quadratic effect on final weight, average daily gain and feed intake, the maximum inclusion of crude glycerin was of 2.77%, for higher daily intake. For the ADG, the level of 2.76% of crude glycerin allowed the best gain and final weight, despite any effect on food conversion. There was a significant effect on the incidence of diarrhea (p=0.014) when 2% of crude glycerin was included in the diet. There was a linear decreasing effect on the percentage of GIT (p=0,006), small intestine (p=0,038), kidneys (p=0,089) and liver (p=0,037) of piglets that did not have glycerin in the diet. We observed a quadratic effect on the relative weight of the spleen and pancreas of piglets, the level of 2.73% of crude glycerin resulted in lower pancreas weight, and 3.04% of glycerin increased spleen weight. The level of 2.76% of crude glycerin promotes the highest weight gain for piglets in the nursery phase.

“…In this context, glycerin appears to be the only byproduct associated with the biodiesel production chain whose energy value can favorably contribute to diets for pigs. In addition to its high level of metabolizable energy (around 3,579 kcal/kg), which is similar to that of corn (around 3,340 kcal/kg) (ROSTAGNO et al, 2011), glycerin is considered palatable to animals, as it is a sweet liquid, and can be used by pigs as glycogenic or lipogenic source (JAGGER, 2008). However, its nutritional value and influence on pig diets may vary according to several factors; e.g., type of feedstock employed in the biodiesel production, chemical characterization, evaluation method used in the process, inclusion level of the test feed, statistical analysis, among others.…”

“…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.

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.

This experiment was conducted to investigate the effects of feed conditioners (single-layer, double-layer and retentionconditioner) on the growth performance, meat quality and intestinal morphology of pigs throughout the growing to finishing phase. A total of 96 growing pigs ((28.70±3.20) kg) were selected and randomized into three treatment groups with four replicates per group. Eight pigs were used per replicate for the 17-week feeding trial. The grower diet was given at 0 to 6 weeks and a finisher diet was given at 6 to 17 weeks. The treatments were as follows: SC diet (control; single-layer conditioning), DC diet (double-layer conditioning), and RC diet (retention-conditioning). Starch gelatinization was significantly higher (P<0.05) in the RC treatment than in the SC treatment, however, there was no significant difference in the starch gelatinization between the DC group and the RC group. In the growing phase, the feed to gain index (F:G) was significantly lower (P<0.05) in the RC group than in the SC and DC groups. Between growing and finishing, the F:G was the lowest (P<0.05) in the SC group compared to the RC or DC group. Drip loss, a measurement of meat quality, was significantly lower (P<0.05) in longissimus dorsi tissue collected from pigs fed the RC diet than in tissues collected from pigs fed the SC diet. The intestinal quality of the duodenum and jejunum tissues showed a significant increase (P<0.05) in the crypt depth and villus height in the RC group compared to the SC-or DC-treated pigs. These results demonstrated that the retentionconditioner treatment decreased the F:G in growing pigs, improved intestinal morphology and enhanced the meat quality in the finishing pigs. However, the retention-conditioner treatment had a negative impact on growth performance in the finishing pigs.
