“…Biodiesel production from oils and fats of vegetable or animal origin generates glycerin as a by-product, a substance high in energy (HENZ et al, 2014;LAMMERS et al, 2008;SWIATKIEWICZ;KORELESKI;2009) with potential for use in broiler chicken feed at different stages of production (CERRATE et al, 2006;GUERRA et al, 2011;SEHU et al, 2013).…”

The aim of this study was to investigate the effects of including purified glycerin in the diets of broilers from 22 to 42 days of age. Eighty Cobb 500® lineage broilers were distributed in a completely randomized design (CRD) to one of four treatment groups (0, 2, 4 and 6% of purified glycerin inclusion in feed) and five replicates of four birds. The birds were evaluated for performance (weight gain, feed intake and feed conversion); carcass yield; special cuts yield (thigh, drumstick and breast); muscle colour (L* = lightness, a* = redness, b* = yellowness); and crude protein, ether extract and moisture content of the breast muscle. Inclusion of purified glycerin in the diet did not affect (p > 0.05) any of the growth performance indicators, which demonstrated the technical feasibility of including up to 6% glycerin in the diet. Similarly, there was no effect on carcass yield; special-cut yields; muscle colour (L* = lightness, a* = redness, b* = yellowness); or crude protein, ether extract and moisture content of breast muscle. The inclusion of purified glycerin at up to 6% in the diet proved to be feasible in broilers treated from 22 to 42 days of age.

“…The energy value of CG, according to Henz et al (2014), may vary according to its level of inclusion in the diet, as well as other factors such as the age and sex of the animals. In addition, the composition of CG may influence its energetic value, such as, its content of glycerol, fatty acids, and methanol (Dozier et al, 2011).…”

“…After going through the refinement process, it can be employed in the pharmaceutical industry, the production of cosmetics, the military, and the food industry (Sehu et al, 2012). In this sense, research has been developed with the purpose of analyzing the use of glycerin in its crude form as an alternative to energetic foods in the diet of nonruminant animals, thus avoiding the refinement process (Silva et al, 2012;Henz et al, 2014).…”

The energetic values of crude glycerin (CG) were determined for broilers at different ages using the method proposed by Matterson and by polynomial regressions. Two trials were performed with broilers from 11 to 21 and from 31 to 41 days of age. The birds were distributed in a completely randomized experimental design with a reference ration (RR), without CG, and three ration tests with replacement of 5%, 10%, and 15% of RR by CG. The metabolizable energy values were calculated by the Matterson method, and the apparent metabolizable energy (AME) values were used in polynomial regression analysis. The mean values of AME, apparent corrected for nitrogen balance (AMEn), metabolizable coefficient of gross energy (CAMEB), and corrected for nitrogen balance (CAMEBn) of CG, for the phase from 11 to 21 days by the Matterson method were 10.08 MJ kg-1, 10.04 MJ kg-1, 67.06%, and 66.74%, respectively. The inclusion of CG presented an increasing linear effect for CAMEB and CAMEBn in this period. From 31 to 41 days, these values were 10.38 MJ kg-1, 10.27 MJ kg-1, 69.02%, and 62.24%, respectively. The predicted AMEn value through the polynomial regression equations was 10.49 MJ kg-1 and 10.18 MJ kg-1, respectively. According to the equations proposed by Matterson, the crude glycerin EMAn values for broilers from 11 to 21 and 31 to 41 days of age were 10.04 MJ kg-1 and 10.26 MJ kg-1, respectively. According to Adeola's method the AMEn values were 10.49 and 10.20 MJ kg-1 for each phase.

“…De acordo com dados apresentados na literatura a GB apresenta uma energia metabolizável aparente (EMA) entre 3353 e 3815 kcal kg -1 , valores estes que se assemelham aos determinados para o milho, 3.381 kcal kg -1 (Rostagno et al, 2011;Henz et al, 2014a), ingrediente comumente utilizado na formulação das dietas para aves. Porém, os valores enérgicos e a composição da GB, encontrados na literatura apresentam grande variação (Jung e Batal, 2011a), isso porque no processo de produção do biodiesel podem ser utilizadas diferentes matérias primas bem como processos.…”

“…Segundo Mandalawi et al (2014) o conteúdo energético da GB depende primariamente da concentração de glicerol que está possui. Henz et al (2014a) determinaram a energia metabolizável aparente corrigida pelo balanço de nitrogênio (EMA n ) da GB para frangos de corte em diferentes fases (11 a 20; 21 a 30 e 31 a 40 dias de idade), com níveis de 3, 6, 9, 12 e 15% de inclusão na ração referência e observaram valores médios de 3353, 3815 e 3667 kcal kg -1 de EMA n para as respectivas idades estudadas. E coeficientes de metabolizabilidade (CM) de 75,10, 85,50 e 82,84%, respectivamente.…”

REVISÃO Palavras chave adicionaisCoproduto. Desempenho. Valor energético. resUMo A glicerina bruta (GB) é um coproduto gerado no processo de produção do biodiesel, do qual representa 10% do produto final. A utilização da GB na alimentação de animais não-ruminantes torna-se interessante, pois apresenta um alto teor de energia bruta e, ainda, a sua utilização pode proporcionar o retorno de parte das matérias-primas empregadas na produção de energia à cadeia alimentar, dando origem a produtos de elevado valor nutritivo. O emprego da glicerina na sua forma bruta como alimento energético vem sendo estudado como uma alternativa para a redução do custo com a alimentação animal, além de proporcionar um destino ambientalmente correto a esse coproduto. Porém, os valores enérgicos e a composição da GB, encontrados na literatura, apresentam grande variação, porque no processo de produção do biodiesel podem ser utilizadas diferentes matérias primas bem como diferentes processos. Além disso, a GB pode apresentar altas concentrações de metanol e sal (sódio ou potássio), devido a utilização do metanol e hidróxido de sódio ou potássio durante o processo de produção do biodiesel. Neste contexto, é necessário o entendimento da capacidade da utilização da GB e seus possíveis efeitos adversos em frangos de corte. Perante estes factos, o objetivo desta revisão é caracterizar a GB como um alimento alternativo para frangos de corte, bem como os fatores que devem ser avaliados antes da sua utilização.inforMation Cronología del artículo. Recibido/Production and use of crude glycerin in the feed of broilers sUMMarY Crude glycerin (GB) is a byproduct generated during the production of biodiesel process, which represents 10% of the final product. The use of GB in non-ruminant animal feeding becomes interesting because it presents a high gross energy content, although its use can result in the return of part of the raw materials used in energy production back to the food chain, leading to high nutritional value products. The use of glycerin in its raw form as an energy food has been studied as an alternative to reduce the cost of animal feed, as well as providing an environmentally friendly destination to this coproduct. However, energetic values and GB composition in the literature show wide variation, what may be attributed to the fact that in the biodiesel production process various materials and processes may be used. Furthermore, GB can have high concentrations of methanol and salt (sodium or potassium), due to the use of methanol and sodium or potassium hydroxide during the biodiesel manufacturing process. In this context, the understanding of the utilization ability of GB and possible adverse effects in broilers is required. Thus, the aim of this review is to characterize GB as an alternative feed for broiler chickens, as well as the factors that must be evaluated before its use can be implemented. additional keYwordsCoproduct.
