“…In this sense, the DC and MC of the energy from the diets increased because the glycerin has higher coefficients than control diet. Higher amounts of dietary metabolizable and digestible energy with glycerin inclusion in the basal diet were also reported by Silveira et al (2015), who evaluated a product with 75% glycerol and 14% fatty acids.…”

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.

“…Furthermore, ileal digestibility of glycerol is very high (>99%) for diets containing crude glycerin (Oliveira et al, 2014). In addition, Silveira et al (2015) evaluated crude glycerin (0, 5, 10, and 15%), and registered that the digestible energy coefficient increased with the addition of glycerin, due to the fact that it is very digestible compared with regular feed. According to Robergs and Griffin (1998), glycerol is absorbed through the portal system and goes straight to the liver; after that, glycerin is transformed into glycerol-3-phosphate by glycerol kinase, and then it is oxidized to dihydroxyacetone phosphate on the outer face of the inner mitochondrial membrane, and goes through the glycolytic pathway for energy production.…”

Performance and serum parameters of growing pigs fed semipurified glycerin ¤ Desempeño productivo y parámetros séricos de cerdos en crecimiento alimentados con glicerina semipurificada Desempenho e parâmetros séricos de suínos em crescimento alimentados com glicerina semipurificada Rei, Praça Frei Orlando, 170, Centro, CEP 36307-352, São João Del-Rei, MG, Brasil. (Received: November 16, 2015; accepted: August 16, 2016) AbstractBackground: the use of semi-purified glycerin in pig diets has been studied as an alternative energy source. Objective: to evaluate growth performance and serum levels of glucose, triglycerides, cholesterol, and urea in pigs fed diets containing semi-purified glycerin during the growth phase. Methods: forty barrows with an initial weight of 27.30 ± 1.74 Kg, distributed in a randomized complete block design with four treatments and five replicates were used. The dietary treatments were a combination of corn and soybean meal diets with the addition of 0, 5, 10 or 15% semi-purified glycerin. The experimental period lasted 27 days and was divided into two periods. Results: during Period 1, pig performance did not differ with the inclusion of semi-purified glycerin in the diet. In Period 2, an improvement in average daily weight gain was observed. In the total period, an improvement was observed in the average daily weight gain, feed/gain ratio and final weight of the animals. However, serum parameters were not affected by the inclusion of semi-purified glycerin in the diets. Conclusion: the addition of up to 15% semi-purified glycerin to the diet of growing pigs improves growth performance without affecting serum parameters.Keywords : cholesterol, co-product, glucose, glycerol, triglycerides, urea. 12Rev Colomb Cienc Pecu 2017; 30:11-20 Verussa GH et al.

“…Groesbeck et al (2008), relataram que o valor energético do milho e da glicerina são semelhantes, demonstrando um grande potencial do coproduto em substituir parte desse cereal na dieta. Segundo Silveira et al (2015) se a produção de suínos e aves, utilizar 10% de glicerina bruta nas rações, esses mercados seriam capazes de consumir toda a glicerina gerada em demasia no Brasil. No entanto, não há estudos suficientes para estabelecer um nível ideal de glicerina nas rações, sem haver comprometimento no desempenho dos animais.…”

resUMoO objetivo do presente trabalho, foi avaliar o efeito da inclusão de diferentes níveis de glicerina bruta nas rações, sobre o desempenho de suínos em crescimento e terminação. Foram utilizados 60 suínos F1 (30 machos e 30 fêmeas), oriundos do cruzamento entre fêmeas Naïma e machos da linhagem comercial P76, com peso inicial de 18,46 ± 1,38 kg, distribuídos em delineamento inteiramente casualizado, com 4 tratamentos e 5 repetições, sendo 3 animais por unidade experimental. As rações foram formuladas à base de milho e farelo de soja, com a inclusão de 0, 5, 10 e 15% de glicerina bruta. As características de desempenho avaliadas foram: ganho de peso, consumo de ração e conversão alimentar. Não foi observada influência (p>0,05) da inclusão de glicerina bruta nas rações sobre as características de desempenho avaliadas nas fases de crescimento e terminação. Recomenda-se a inclusão de até 15% de glicerina bruta nas rações de suínos em crescimento e terminação, sem efeitos prejudiciais ao desempenho produtivo. Levels of crude glycerin in the feed of pigs in the phases of growth and termination sUMMarYThe objective of this study was to evaluate the effect of different levels of crude glycerine in the rations on the performance of growing and finishing pigs. 60 F1 pigs (30 males and 30 females), deriving from the cross between Naïma females and commercial line P76 males, with an initial weight of 18.46 ± 1.38 kg, distributed in a completely randomized design, with 4 treatments and 5 replications, with 3 animals per experimental unit. The rations were formulated on the basis of corn and soybean meal, with the inclusion of 0, 5, 10 and 15% of crude glycerine. The performance characteristics evaluated were: weight gain, feed intake and feed conversion. There was no influence (p>0.05) found in the inclusion of crude glycerine in the rations on the performance characteristics evaluated in the phases of growth and termination. The inclusion of up to 15% of crude glycerine in the diets of growing and finishing pigs is recommended, without harmful effects for productive performance. INTRODUÇÃOO biodiesel é um biocombustível derivado de fontes renováveis, podendo ser obtido a partir de óleos vegetais ou gordura animal. Em geral, sua produção consiste na transesterificação do óleo ou gordura com álcoois (metanol ou etanol) através de catalizadores (geralmente hidróxido de sódio), ocorrendo a separação dos triglicerídeos em ésteres metílicos (biodiesel) e glicerina bruta (Hansen et al., 2009). O termo glicerol, refere-se ao componente químico puro 1,2,3-propanotriol, enquanto a glicerina bruta aplica-se aos produtos na forma comercial, contendo normalmente, 95% ou mais de glicerol (Mota et al., 2009). De acordo com Carvalho et al. (2012), a glicerina é o principal coproduto resultante da produção de biodiesel, correspondendo cerca de 10% do volume total produzido. Nos últimos anos, com a inclusão obrigatória do biodiesel ao óleo diesel (Lei 11.097), observou-se um grande aumento na produção desse biocombustível, e consequente...
