“…Essas divergên-cias entre resultados de pesquisa podem estar relacionadas à composição química das glicerinas utilizadas nos experimentos que podem varias quanto a fonte de obtenção (Bernardino et al 2014), teores de metanol, glicerol e sódio dentre outros (Dozier et al 2011) Os resultados do eritrograma, proteína plasmática total e fibrinogênio (Quadro 3) e do leucograma (Quadro 4) apresentaram valores médios dentro da faixa de normalidade para a espécie em todos os grupos e momentos. Demonstrando que a inclusão de glicerina não acarreta nenhum prejuízo na hematologia de frangos de corte.…”

RESUMO.-Em função da grande variabilidade na composição da glicerina oriunda do biodiesel, torna-se imprescindível a busca por informações que contribuam estabelecê--la com uma alternativa na alimentação de aves. O objetivo deste estudo foi avaliar o efeito da inclusão de glicerina com alto de teor de metanol em dietas para frangos de corte sobre o desempenho e parâmetros sanguíneos. Due to the great variability in the composition of glycerin derived from the biodiesel, it is essential to search for information which helps establish it with an alternative in poultry feed. The aim of this study was to evaluate the effect of inclusion of glycerin with high methanol content in diets for broilers on performance and blood parameters. They used 90 Cobb male broiler chicks with 8 days old, distributed in a completely randomized design with three treatments (0, 6 and 12% glycerin inclusion levels) and six replications of five birds each, a total of 18 experimental units. Diets were formulated based on corn and soybean meal to meet the nutritional requirements and glycerin used contained 1.4% methanol and 3158Kcal/kg of metabolizable energy. At 21, 33 and 42 days of age the remains of feed and the birds were weighed to determine the feed intake, body weight, body weight gain and feed conversion. Were collected 1 to 3ml of venous blood of the birds during the last days of each phase (19 to 21, 31 to 33 and 40 to 42 days of age) for determination of hematocrit, hemoglobin concentration, reticulocyte total plasma proteins and fibrinogen. To evaluate the serum biochemistry were collected venous blood of birds without anticoagulant, only in the final phase (40 to 42 days). Performance data, hematological and biochemical obtained were submitted to analysis of variance. We used the Tukey test with α = 0.05 probability, to compare the means. There were no statistical difference between the treatments on the performance parameters and biochemical and blood parameters, except plasma proteins for between 19 and 21, which increased with the inclusion of glycerin, and reticulocytes that reduced with the inclusion of glycerin. The inclusion of up to 12% glycerin with 1.4% residual methanol in broiler diets (8 to 42 days of age) can be performed without loss in performance and health.

“…Evaluating three different glycerin sources (crude, mixed and semi-purified) and four inclusion levels (1.75, 3.50, 5.25 and 7.0%), Bernardino et al (2014) observed that broilers fed diets containing crude and semi-purified glycerin linearly increased serum glycerol concentrations and concluded that the studied glycerins can be included in the diet at up to 7% without impairing the performance of broiler chickens from 8 to 21 days old. Mandalawi et al (2014) tested 2.5, 5.0, 7.5 and 10% glycerin in the feed of broilers from 1 to 21 days and concluded that glycerin can be used to replace the dietary energy sources at up to 10% without any negative effect on the broiler performance.…”

This paper aimed to evaluate the metabolizability, performance and economic viability of purified glycerin inclusion in balanced diets fed to chicken broilers from 8 to 21 days old. Two experiments were conducted. In the first experiment, 100 broilers (14 days old) were distributed in a completely randomized design into two treatments, with five replications of 10 broilers. Treatments consisted of a control diet and a test diet, in which purified glycerin replaced 10% of the control diet. In the second experiment, 200 broilers (8 days old) were distributed in a completely randomized design into four treatments (0, 2, 4 and 6% of purified glycerin inclusion), with five replications of 10 broilers. The weight gain, feed intake, feed conversion, final weight, apparent metabolizable energy (AME), nitrogen-corrected apparent metabolizable energy (AMEn), metabolizability coefficients of dry matter (DMMC), crude protein (CPMC) and gross energy (GEMC), and the cost of feed per kg of broiler produced were evaluated. The AME, AMEn, DMMC, CPMC and GEMC from the purified glycerin were 3790 and 3560 kcal/kg, and 83.72, 71.52 and 86.27%, respectively. The glycerin levels did not affect (p>0.05) any of the performance characteristics (weight gain, feed intake, feed conversion and final weight). The lowest feeding cost and the highest gross margin were obtained for broilers fed with 6% purified glycerin. The inclusion of 6% purified glycerin in balanced diets for broilers from 8 to 21 days old was technically and economically feasible.

“…No entanto, os cuidados com o manejo da cama devem ser aumentados de maneira a minimizar a umidade (Guerra et al, 2011). Bernardino et al (2014), concluíram que a inclusão de glicerina bruta de soja a partir de 35,0g/kg, a glicerina bruta mista em todos os níveis avaliados e a glicerina sem purificada inclusa em 17,50g/kg promoveram melhores resultados de conversão alimentar em relação aos obtidos para as aves alimentadas com ração sem glicerina.…”

The use of soy by-products in poultry feed has proven to be an important sustainable alternative, being capable of minimizing the environmental damage caused by the disposal of these residues and at the same time reducing the cost of production. However, for the use of these by-products in poultry feeding, it is necessary to know their chemical composition, antinutritional factors and also necessary measures to reduce these factors, as well as the best levels of inclusion that must meet the nutritional requirements of the animals in each production phase. In this context, the purpose of this review is to demonstrate the potential use of soy by-products (soy husk, soy acid oil, glycerin, soybean chopsticks, soy gum and okara) in the feeding of broilers, laying hens and cutting and laying quails, as well as the adverse effects that each can cause on animal performance. To carry out this review, analysis was carried out in several scientific studies that used soy by-products in the feeding of broilers and laying hens. It can be concluded that the potential for using soy by-products in Brazil is enormous, which expands the alternative ingredients that can replace soybean meals in poultry feed, without causing damage to performance, intestinal health, biochemical and hematological parameters, in addition to reduce the environmental pollution generated by the inappropriate disposal of these residues, as these ingredients could be a way to reduce the costs of diets.
