“…Estes resultados estão de acordo com outros pesquisadores, que, analisando níveis de inclusão de glicerina bruta na ração, relataram que a sua utilização na ração não afetou o desempenho de suínos na fase de creche (Lammers et al, 2007), crescimento e terminação (Mourot et al, 1994;Berenchtein, 2008 Groesbeck et al (2008) avaliaram os efeitos da inclusão de 3 e 6% de glicerina bruta e 6 e 12% de glicerina bruta associada com óleo de soja sobre o desempenho de leitões na fase de creche e observaram um efeito linear positivo no ganho diário de peso dos leitões que receberam glicerina bruta na dieta, sem, no entanto, afetar o consumo diário de ração e a conversão alimentar. A inclusão de até 30% de glicerol bruto na dieta de suínos em crescimento e terminação, segundo Kijora et al (1995), resultou em menor ganho diário de peso e pior conversão alimentar, sem, entretanto, afetar o consumo diário de ração para o maior nível.…”

“…Há estudos cujos resultados indicam a possibilidade de uso desse subproduto como fonte de energia para suínos, pois possui em torno de 4.320kcal de energia bruta por kg para o glicerol puro (Mourot et al, 1994;Kijora et al, 1995;Lammers et al, 2007). Porém, a glicerina bruta possui entre 80,0 e 95,0% de glicerol (Ramos et al, 2000).…”

RESUMOAvaliou-se o efeito da substituição do milho por glicerina bruta em dietas para suínos em terminação. Foram utilizados 80 suínos, machos castrados, híbrido comercial, com média de peso de 67kg, em um experimento em delineamento inteiramente ao acaso, com cinco tratamentos e oito repetições, com dois animais por unidade experimental. Os tratamentos foram: 0,0; 4,0; 8,0; 12,0 e 16,0% de glicerina bruta em substituição ao milho nas dietas. A substituição do milho por glicerina bruta não afetou as características de desempenho (P≥0,05). Observaram-se efeito linear crescente de tratamento (P≤0,05) sobre a espessura de toucinho na carcaça e efeito linear decrescente de tratamento (P≤0,05) sobre a perda de líquido no descongelamento e na força de cisalhamento. A glicerina bruta pode substituir em até 16,0% do milho da dieta para suínos em terminação, sem prejuízos do desempenho e rendimento de carcaça, com melhoras na qualidade da carne.

“…Several authors have evaluated the effects of adding crude glycerin to weanling (Groesbeck et al, 2008;Zijlstra et al, 2009) and growing-finishing pig diets (Kijora et al, 1995;Lammers et al, 2008a;Della Casa et al, 2009;Mendoza et al, 2010). However, studies with sows fed diets containing crude glycerin have rarely been conducted (Schieck et al, 2010a).…”

“…Crude glycerin inclusion in the diets of growing-finishing pigs has also provided conflicting results as regards growth performance. Some studies found enhanced ADG and ADFI in pigs fed glycerin (Kijora et al, 1995;Schieck et al, 2010b), while others reported negative effects (Della Casa et al, 2009) or no effects on the growth rate and feed efficiency (Lammers et al, 2008a;Mendoza et al, 2010).…”

The continued growth in biofuel production has led to a search for alternative value-added applications of its main by-product, crude glycerin. The surplus glycerin production and a higher cost of feedstuffs have increased the emphasis on evaluating its nutritive value for animal feeding. The aim of this research was to evaluate the effect of the dietary addition of crude glycerin on sow and litter performance, and to determine the serum concentrations of hormones related to energy metabolism and feed intake in sows during gestation and lactation. A total of 63 sows were assigned randomly to one of three dietary treatments, containing 0, 3 or 6% crude glycerin (G0, G3 and G6, respectively) added to a barley-soybean meal-based diet. During gestation, none of the dietary treatments had an effect on performance, while during lactation, glycerin-fed sows consumed less feed than those fed the control diet (3.8 v. 4.2 kg DM/day; P = 0.007). Although lactating sows fed the G3 diet had a higher BW loss than those fed the control diet (−20.6 v. −8.7 kg; P = 0.002), this difference was not reflected in litter performance. In gestation, the inclusion of glycerin did not affect blood concentrations of insulin or cortisol. However, pregnant sows fed diets supplemented with glycerin showed lower concentrations of acyl-ghrelin and higher concentrations of leptin (−55 and +68%, respectively; P < 0.001). In lactating sows, there were no differences between dietary treatments for any of the hormones measured. Pre-prandial acyl-ghrelin concentrations were positively correlated with cortisol concentrations during gestation ( r = 0.81; P = 0.001) and lactation ( r = 0.61; P = 0.015). In conclusion, the inclusion of up to 6% crude glycerin did not affect the performance of sows during the gestation period; however it had a negative effect on the feed intake and weight loss of lactating sows. Moreover, further research is needed to elucidate the potential relationship between glycerin inclusion levels in the diet and the serum concentrations of hormones related to feed intake and energy balance control.Keywords: crude glycerin, feed intake, metabolic hormones, sow ImplicationsAccording to our results, crude glycerin up to 6% could be added to the diet from confirmation of pregnancy without affecting the performance of pregnant sows. Our results also suggest a relationship between the inclusion of glycerin in the diet and the serum concentrations of feed intake regulating hormones, such as acyl ghrelin and leptin; but more studies are needed to increase the understanding of interactions between diet composition and hormone concentration.

Vortrag, gehalten auf dem DGF-Symposium ,,Einsatz von Phospholipiden, Fetten und Olsaaten im Mischfutter zur Steigerung der Leistung und Gewinnung hochwertiger Nahrungsmittel" im November 1995 in Wallenhorst.The utilization of two different technical glycerols from "Biodiesel" production as a feed component was investigated in a feeding experiment using 6 x 6 barrows (Pietrain x Fl). Glycerol was included into the diets in amounts of 5 and 10% (Diets 3-6). The control diet [l] contained no glycerol, whereas diet 2 was supplemented with 10% pure glycerol. The contents of dry matter of the two technical glycerols were 77.6% and 99.7%. respectively. The contents of ash were 18.7% and 4.8010, respectively. The feeding performance of the pigs in the growing period was elevated by 7.5% in all groups which received glycerol compared to control group 1. The improvement of the daily gain depended strongly on the actual intake of glycerol in this growing period. This effect could not be observed in the finishing period. The dietary treatments did not have any significant effects on meat quality. Glycerol reduced the water content in tendency. There were no differences between technical and pure glycerol concerning the feeding performance. A possible contamination with ash and a dilution with water should be considered in regards to the nutritive value in pigs.Bewertung von technischem Glycerol aus der ,,Biodiesel"-Produktion fur die Schweinernast. In einem Futterungsversuch mit 6 x 6 Borgen (Pietrain x F1) wurde die Einsatzmoglichkeit von zwei verschiedenen technischen Glycerinen aus der Biodieselproduktion wahrend einer Mastperiode als Rationskomponente in Hohe von 5 bzw. 10% Glycerin im Vergleich zu einer Kontrollgruppe 1 (ohne Glycerin) und einer Kontrollgruppe 2 (10% reines Glycerin) gepruft. Der Trockenmassegehalt (TS) der technischen Glycerine \ag bei 77.6% bzw. 99,7O/o, und die Rohaschegehalte betrugen 18,7% bzw. 4.8%. Unabhangig von der Qualitat der Glycerine war die Mastleistung in der Vormastperiode gegeniiber der Kontrollgruppe 1 in allen Glyceringruppen um durchschnittlich 7.5% erhoht. Dabei bestand in dieser Periode ein enger Zusammenhang zwischen der tatsachlichen Glycerinaufnahme und der taglichen Lebendmassezunahme. In der Hauptmastperiode wurde dieser Effekt trotz ebenfalls tendenziell erhohter Futteraufnahme nicht bestatigt. Die Fleischbeschaffenheit wurde nicht signifikant verandert. In der Tendenz ergaben sich geringere Wassergehalte im Fleisch nach Glyceringabe. Zwischen reinem und technischem Glycerin gab es keine Unterschiede in der erzielten Mastleistung. Bei Einsatz von technischen Glycerinen als Futterkomponente muO hinsichtlich der Einsatzempfehlungen der Mineralstoff-und Wassergehalt berucksichtigt werden.
