“…In present trial, we also observed that the relative cloacal fat weight tended to increase in broilers fed with glycerol supplemented, especially at a level of 10% CG due to overestimation of metabolically energy assigned to glycerine [18] . Similarly, Lessard et al [6] have also found out that inclusion of 5% glycerol had increased the cloacal fat pad weight. However, the variances among treatments had no statistical meaning for this finding for present trial.…”

“…Glycerine, also known as glycerol or glycerin, is a by-product of biodiesel production and usage of this product as an energy source for animal diets has been got attention in recent years [2][3][4] . Glycerine has been evaluated for poultry as a feed ingredient which provides energy for cellular metabolism [5][6][7][8][9] . Moreover, several studies have been performed for understanding effects of dietary glycerine addition on performance in broiler chickens [4,[7][8][9] , quails [10] , and laying hens [11] .…”

The aim of the current study was to evaluate the effects of graded levels of crude glycerine addition to diets on growth and economic performance, carcass yield, organ weights and moisture levels of meat in broiler chickens. For this purpose, a total of 270 one day old male chicks (Ross 308) were randomly divided into 3 equal groups which fed with isocaloric and isonitrogenous diets with graded levels (0%, 5% and 10%, respectively) of crude glycerine. Each of experiment group was constituted by 5 subgroups with 18 birds each. The birds had ad libitum access to feed and water until termination of the experiment at d 42. Results indicated that 5% dietary crude glycerine addition improved body weight, body weight gain and feed conversion ratio compare with birds fed with basal diet at d 42 (P<0.01). Similarly, dietary 10% crude glycerine supplementation also increased growth performance and improved FCR in broiler chickens at 28 th and 42 nd days of experiment (P<0.05 and P<0.001, respectively). Moreover, birds fed with 5% dietary crude glycerine had showed over 20% higher relative economic efficiency compare than birds fed basal diet. As a conclusion, dietary crude glycerine addition improved growth and economic performance and Feed Conversion Ratio of broilers in both supplementation levels.

Bu amaçla toplam 270 adet bir günlük yaşta erkek broyler civciv (Ross 308) her biri izokalorik ve izonitrojenik olan ve artan düzeylerde (sırasıyla %0, %5 ve %10) ham gliserin içeren yemlerle beslenen üç eş gruba ayrılmıştır. Her bir deneme grubu her biri kendi içinde 18 adet civciv içeren 5'er alt gruba ayrılmıştır. Hayvanlar denemenin sonlandığı 42. güne kadar yem ve suya ad libitum olarak ulaşmışlardır. Deneme sonunda %5 düzeyinde ham gliserin ilavesinin canlı ağırlık, canlı ağırlık artışı ve yemden yararlanma oranlarını bazal rasyonla beslenen hayvanlara göre önemli ölçüde iyileştirdiği belirlenmiştir (P<0.01). Benzer olarak rasyona %10 düzeyinde ham gliserin ilavesi denemenin 28. ve 42. günlerinde büyüme performansını arttırmış ve yemden yararlanma oranını iyileştirmiştir (sırasıyla, P<0.05 ve P<0.001). Buna ilaveten, %5 ham gliserin ile beslenen hayvanlar bazal rasyonla beslenenlere göre %20 daha yüksek göreceli ekonomik etkinlik göstermiştir. Sonuç olarak rasyona ham gliserin ilavesi, her iki düzeyde de, broylerlerde büyüme ve ekonomik etkinlik ile Yemden Yararlanma Oranı'nı iyileştirmiştir.

“…Several researchers have reported that glycerin is an acceptable feed ingredient for poultry (Campbell and Hill, 1962;Brambilla and Hill, 1966;Lin et al, 1976;Lessard et al, 1993;Simon et al, 1996Simon et al, , 1997Cerrate et al, 2006;Swiatkiewicz and Koreleski, 2009;Min et al, 2010).

“…Adding glycerin up to 5% of the diet had no adverse effects on growth performance or carcass yield in broilers (Lessard et al, 1993;Simon et al, 1996;Cerrate et al, 2006). Increasing dietary glycerin above 10%, however, can adversely affect growth performance and meat yield of broiler chickens (Simon et al, 1996;Cerrate et al, 2006), although this may be due to reduced flowability of feed observed when 10% glycerin was supplemented (Cerrate et al, 2006).…”

“…The influence of glycerine supplementation on weight gain, feed intake and feed conversion ratio was beneficial when included in the complete diet at levels from 5 to 10 %. Broilers fed a 20 % glycerine diet had the same weight, feed intake or feed conversion as control diet (Campbell and Hill, 1962;Lin et al, 1976;Lessard et al, 1993;Simon et al, 1996).…”

Scientific Opinion on the abiotic risks for public and animal health of glycerine as co‐product from the biodiesel production from Category 1 animal by‐products (ABP) and vegetable oils

Following a request from the European Commission, the European Food Safety Authority (EFSA) was asked to deliver a scientific opinion on the abiotic risks for public and animal health of glycerine as co-product from the biodiesel production from Category 1 animal by-products (ABP) and vegetable oils. Crude glycerine is used as an energy-rich feed component in animal diets. Glycerine derived from biodiesel produced from vegetable oils may contain up to 0.5 % methanol and 1 % sodium, used as catalysts in the biodiesel production process. Inclusion rates of such produced glycerine at levels of up to 15 % in the diet of ruminants and up to 10 % in monogastric animals are well-tolerated and exerted no adverse effects on animal health. In contrast, these findings would need to be confirmed for crude glycerine derived from biodiesel production using feedstocks (input materials) other than vegetable oils, as the production process is slightly different. More importantly, no data are available on the levels of possible contaminants of crude glycerine derived from biodiesel production using recycled animal fats or animal by-products classified as category 1 materials due to chemical risk. Therefore, the Panel on Contaminants in the Food Chain recommends the collection of data on the presence of impurities and contaminants in crude glycerine from biodiesel production that is used as animal feed component. SUMMARYFollowing a request from the European Commission, the European Food Safety Authority (EFSA) was asked to deliver a scientific opinion on the risks for public and animal health of glycerine as a coproduct from the biodiesel production from Category 1 animal by-products (ABP) and vegetable oils. The Panel on Contaminants in the Food Chain (CONTAM Panel) noted that the increasing demand for alternative fuels for diesel engines has resulted in a significant increase in biodiesel production. Subsequently, diverse input materials (feedstocks) including recycled animal fats and ABP are used for this purpose. The main co-product of biodiesel production is crude glycerine that is used as an energy-rich feed component in animal diets. Previous assessments of crude glycerine from biodiesel production were confined to the evaluation of biodiesel produced from vegetable oils, intended for human consumption. Data show that inclusion rates of such produced glycerine up to a level of 15 % in the diet of ruminants and up to 10 % in the diet of monogastric animals had no adverse effects on animal health. These findings indicated also that the residual amounts of methanol (up to 0.5 % in the crude glycerine fraction) and sodium (up to 1 % in crude glycerine) used as catalysts in the biodiesel process exerted no adverse effects. These findings are in agreement with the known toxicological data for the individual compounds, but need to be confirmed for glycerine derived from biodiesel using other sources than vegetable oils as feedstock material, as in this case the production process can be different.The CONTAM Panel noted th...
