“…Compared with quails fed without the addition of glycerin (control), quails fed with glycerin, considering all levels of inclusion of crude vegetable glycerin to the diet, had increased abdominal fat (Table 3). Similarly to the results obtained in this research, Batista et al (2013) evaluated quails aged 15-35 days fed with levels of inclusion of 4, 8, 12, and 16% of crude vegetable glycerin and semi-purified vegetable glycerin, and observed no significant differences in the yield of carcass, breast, and thigh + drumstick; however, there was a significant difference in the yield of abdominal fat. In contrast, Peña Martínez (2012) evaluated broiler chickens fed a diet containing 2% (age of 1-21 days) and 4% (22-40 days) soy glycerin and found a significant difference in carcass yield but no significant difference in the yield of commercial meat cuts (breast and leg), nor abdominal fat.…”

-The objective of this work was to evaluate the effect of the inclusion of vegetable and mixed glycerin in the diet of broiler quail (Coturnix coturnix coturnix) on animal performance, yield of carcass and organs, and physical and sensory characteristics of the meat. A total of 432 quails aged 1-42 days were used in a completely randomized design with a 4×2+1 factorial arrangement (5, 10, 15, and 20% inclusion of vegetable or mixed glycerin, besides one treatment without glycerin) with 4 replicates of 12 birds each. Feed intake, weight gain, feed conversion, yield (carcass, breast, thigh+drumstick, heart, liver, gizzard, and abdominal fat), and physical and sensory characteristics of the meat. The diet containing mixed glycerin resulted in higher feed intake and feed conversion. The yield of carcass, meat cuts, and organs, as well as the sensory characteristics of the meat, did not vary between the treatments. Abdominal fat content and shear strength were higher in birds fed diets containing vegetable glycerin. The tested glycerin and levels do not interfere with weight gain, yield, and sensory quality of the meat. However, weight gain and feed conversion are lower when mixed glycerin is used, although meat tenderness is higher when 15% vegetable glycerin is used.Index terms: Coturnix coturnix coturnix, carcass yield, meat quality, weight gain. Desempenho, rendimento e características da carne de codornas que receberam rações contendo glicerina vegetal e mistaResumo -O objetivo deste trabalho foi avaliar o efeito da inclusão de glicerinas vegetal e mista na dieta de codorna de corte (Coturnix coturnix coturnix) sobre o desempenho, o rendimento de carcaça e de órgãos, e as características físicas e sensoriais da carne. Utilizaram-se 432 codornas com 1 a 42 dias de idade, em delineamento inteiramente casualizado, no arranjo fatorial 4×2+1 (5, 10, 15 e 20% de inclusão de glicerina vegetal ou mista, mais um tratamento sem glicerina), com 4 repetições e 12 aves cada uma. Avaliaram-se o consumo de ração, ganho de peso, conversão alimentar, rendimento (de carcaça, peito, coxa+sobrecoxa, coração, fígado, moela e gordura abdominal) e características físicas e sensoriais da carne. A dieta com glicerina mista proporcionou maior consumo de ração e conversão alimentar. O rendimento de carcaça, cortes, órgãos, bem como as características sensoriais da carne, não variaram entre os tratamentos. Já a gordura abdominal e a força de cisalhamento foram maiores nas aves que consumiram ração contendo glicerina vegetal. Os níveis e as glicerinas testados não interferem no ganho de peso, nem nos rendimentos e na qualidade sensorial da carne. No entanto, há prejuízo no ganho de peso e na conversão alimentar quando se utiliza glicerina mista, embora a maciez da carne seja maior quando se utilizam 15% de glicerina vegetal.Termos para indexação: Coturnix coturnix coturnix, rendimento de carcaça, qualidade da carne, ganho de peso.

“…This shows that low inclusion levels of glycerin may not be adequate to determine its energy value, because can be underestimated. Working with the inclusion of 10% vegetable semi-purified glycerin (VSG) in quail diets, Batista et al (2013) obtained a GE value of 3,585 kcal/kg, and an AMEn value of 3,068 kcal/kg (FM), and the MCGE was 85.61%.

“…On the other hand, from day 1 to 42, the authors found no difference between the glycerin and control diets. Batista et al (2013), working with inclusion levels of vegetable semi-purified glycerin (4%, 8%, 12%, and 16%), showed that glycerin can be used to make up to 16% of diets, noting that its use will depend on the prices of other ingredients.…”

Semi-purified glycerin in the meat quails feeding

et al. 2014

Three experiments were conducted to determine the nutritional value of semi-purified glycerin (SG), and its economic feasibility for use in meat quail feed. Its effect on the performance, body chemical composition, and carcass yield were assessed. In experiment 1, 22-day-old quails, were housed in metabolic cages, distributed in a completely randomized design (CRD), with three treatments, five replicates, and five birds per repetition, using 75 quails in total. Treatments consisted of a reference diet (RD) and two test diets (TD) in which 8% and 12% SG replaced the RD. The estimated value of nitrogen-corrected apparent metabolizable energy (AMEn) for SG was 2,476 kcal/kg. In experiment 2, 1320 quails (55 quails in each box) were distributed in a CRD with six treatments and four replicates. The treatments consisted of a control diet, based on corn and soybean meal, and five diets with increasing levels of SG (3%, 6%, 9%, 12%, and 15%). There were no effects of SG on the performance variables. The cost per kilogram of live weight produced increased linearly (P<0.05) with the percentage of SG in the diet. The performance data suggest that SG may be included in up to 15% of the diet in 1-to 14-day-old quails. In experiment 3, 1032 quails (43 quails in each box) were distributed under the same conditions as in experiment 2. SG influenced linearly the litter moisture (P<0,05) and body biomass accumulated (BBA), and had a quadratic effect on feed conversion ratio and BBA (P<0,05). The cost per kilogram of live weight produced increased linearly (P<0.05) with the percentage of SG in the diet. Therefore, SG may be used to make-up 10% of the diet of 15-35-day-old quail.

“…Em codornas e frangos de corte, a inclusão de glicerol na dieta pode afetar características de desempenho, como ganho de peso e conversão alimentar (Raber et al, 2009;Batista, 2010), além de reduzir ou aumentar a expressão do RNA mensageiro (mRNA) de alguns genes mitocondriais, como a adenina nucleotídeo translocase (ANT) e a proteína desacopladora (UCP), relacionadas à síntese de ATP e ao estresse oxidativo (Gasparino et al, 2012).…”

Resumo -O objetivo deste trabalho foi avaliar o efeito de dietas com glicerol no desempenho produtivo de codornas japonesas de corte e na expressão do mRNA de genes mitocondriais da proteína adenina nucleotídeo translocase (ANT) e da proteína desacopladora (UCP), envolvidas no metabolismo energético e na resposta ao estresse oxidativo. As codornas foram alimentadas com dietas contendo 0, 8 e 12% de glicerol, em substituição parcial ao milho. Aos 28 dias de idade, o RNA total foi extraído de amostras do músculo do peito e a síntese do cDNA foi feita por meio de qRT-PCR com iniciadores específicos para genes da ANT e UCP, obtidos de Gallus gallus. A conversão alimentar e o consumo de ração foram avaliados para as três dietas testadas. A adição de 8% de glicerol não afetou o desempenho dos animais. No entanto, a adição de 12% aumentou o consumo de ração e piorou a conversão alimentar. O ganho de peso não foi afetado pela inclusão de glicerol na dieta. No grupo alimentado com 8% de glicerol, a expressão da UCP aumentou, mas a da ANT não variou, em comparação ao controle. A expressão da UCP foi menor e a da ANT foi maior no grupo alimentado com 12% de glicerol. A inclusão de 8% de glicerol na dieta não afeta o desempenho de codornas de corte, embora aumente a expressão da UCP. A inclusão de 12% de glicerol piora o desempenho e aumenta a expressão da ANT.Termos para indexação: Coturnix coturnix, estresse oxidativo, fosforilação oxidativa, metabolismo energético. mRNA expression of mitochondrial genes and productive performance of quails fed with glycerolAbstract -The objective of this work was to evaluate the effect of diets containing glycerol on the productive performance of Japanese meat quails and on the mRNA expression of the mitochondrial genes of the adenine nucleotide translocase (ANT) and uncoupling protein (UCP), involved in energy metabolism and oxidative stress response. The quail were fed diets containing 0, 8, and 12% glycerol in partial substitution of corn. At 28 days of age, total RNA was extracted from samples of breast muscle and cDNA synthesis was done with qRT-PCR using specific primers for ANT and UCP genes, obtained from Gallus gallus. Feed conversion and feed intake were evaluated for the three tested diets. The addition of 8% glycerol did not affect performance. However, the addition of 12% glycerol increased feed intake and worsen feed conversion. Animal weight gain was not affected by glycerol inclusion in the diet. In the group fed with 8% glycerol, UCP expression increased, but that of ANT did not vary in comparison to the control. The expression of UCP was lower and that of ANT was higher in the group fed with 12% glycerol. The inclusion of 8% glycerol in the diet does not affect the performance of meat quails, although it increases the expression of UCP. The inclusion of 12% glycerol decreases performance and increases the expression of ANT.
