“…It will be absorbed passively rather than forming a micelle that is compulsory to absorb the medium and long chain fatty acid (Mcmurry & Begley, 2005;Guyton, 1991) AMEn and TMEn value of experimental feed with crude glycerine tended to decrease eventhough not statistically difference when the level of crude glycerine increased. This is due to the increased blood glycerol levels (Kerr, Shurson, Johnston, & Dozier III, 2011;Simon et al, 1996) after crude glycerine is absorbed, the complete renal reabsorption is averted and urine will increase due to glycerol excretion (Kijora, Bergner, Kupsch, & Hageman, 1995). Same result happened in the work of Lammers et al (2008), using crude glycerine in finishing pig, it decreased the metabolizable energy as the crude glycerine inclusion increased from 0 to 20% in the diet.…”

“…Gross energy between both crude glycerines was significantly differrent due to the high amount of crude fat in the CG2. Kerr et al (2011) reported that the amount of fatty acid was the main factor that influence the gross energy value in the crude glycerine, the energy value will be increased as the fatty acid content increased. Even though, this study did not determine the fatty acid content, it can be replaced by crude fat, as it is also known as the ether extract or the free lipid content, the lipid materials may include triglycerides, diglycerides, monoglycerides, phospholipids, steroids, and free fatty acids (Association of American Feed Control Officials [AAFCO], 2014).…”

ABSTRACT.A study was conducted to determine the dry matter digestibility, gross energy (GE), the nitrogen-corrected apparent metabolizable energy (AMEn), and the nitrogen-corrected true metabolizable energy (TMEn) of two crude glycerine from two different sources. The first crude glycerine (CG1) was from a large scale biodiesel producer with high content of glycerol (89.49%) and low content of crude fat (1.73%), meanwhile the second crude glycerine (CG2) was from a medium scale biodiesel producer with lower content of glycerol than CG1 (38.36%) and high content of crude fat (23.63%). Fed rooster assay based on Sibbald (1976) was used in the experiment. The experimental feed consisted of ground corn and three levels of crude glycerine (0, 10, and 20%). Twenty four Hisex brown roosters were housed in metabolic cages. Roosters were force fed with 30 g experimental feed, after 24 hours of fasting. Excreta collection was performed for two days while the roosters were fasting again. The content values of GE, AMEn, and TMEn of CG1 were 4065.18, 2926.59, and 3068.73 kcal kg -1 and for CG2 were 5928.09, 4010.11, and 4054.52 kcal kg, respectively.Keyword: large scale biodiesel producer, medium scale biodiesel producer, Sibbald method.Digestibilidade da matéria seca e energia metabolizável da glicerina bruta originada a partir de óleo de palma usando ensaio de alimentação forçada com galos RESUMO. O presente estudo foi realizado para determinar a digestibilidade da matéria seca, energia bruta (EB), energia metabolizável aparente corrigida pelo balanço de nitrogênio (EMAn) e energia metabolizável verdadeira corrigida pelo balanço de nitrogênio (EMVn) de glicerinas brutas de duas diferentes fontes. A primeira glicerina bruta (GB1) foi obtida de um produtor de biodiesel de grande escala contendo alto teor de glicerol (89,49%) e baixo teor de gordura bruta (1,73%), enquanto a segunda glicerina bruta (GB2) era de um produtor de biodiesel de média escala com menor conteúdo de glicerol do que GB1 (38,36%) e alto teor de gordura bruta (23,63%). O ensaio de alimentação forçada com galos baseado em Sibbald (1976) foi utilizado no experimento. A ração experimental foi composta de milho moído e três níveis de glicerina bruta (0, 10 e 20%). Vinte e quatro galos Hisex brown foram alojados em gaiolas metabólicas. Os galos foram alimentados a força com 30 g da ração experimental após jejum de 24 horas. A coleta de excretas foi realizada durante dois dias enquanto os galos permaneceram novamente em jejum. Palavras chave: produtor de biodiesel de grande escala, produtor de biodiesel de média escala, método Sibbald.

The aim of this study was to evaluate the effect of the inclusion of crude glycerin in post-weaning diets for piglets on growth performance and digestibility. The study was carried out with a total of 360 piglets over a 39 day period. Animals were blocked by body weight (7.7 ± 0.86 kg) and allotted randomly to one of three dietary treatments containing 0, 2.5 or 5% glycerin (G0, G2.5 and G5, respectively). Considering the whole period, glycerin did not affect the average daily gain. However, the average daily feed intake (ADFI) and the feed conversion ratio (FCR) tended to decrease or decreased linearly as the amount of glycerin increased, respectively (p = 0.060 and p = 0.039). The apparent total tract digestibility (ATTD) of dry and organic matter (DM, OM) increased linearly with increasing glycerin in both periods (p ≤ 0.05). At the end of the study, there were no differences between treatments for any of the hormones measured. In conclusion, the FCR and digestibility of DM and OM were improved although the ADFI tended to be lower when glycerin was included at 5%. Consequently, crude glycerin could be used as an alternative ingredient to partially replace sweet whey and wheat in post-weaning diets.
