“…The use of glycerin in swine feeding also casts doubts as to the adequate level of its inclusion in the different production stages; for example, 120 g kg −1 for 15 to 30 kg (Carvalho et al, 2012), 150 g kg −1 for 27 to 48 kg (Verussa et al, 2017), 160 g kg −1 for 67 to 107 kg (Gomide et al, 2012), 150 g kg −1 for 97 to 115 kg (Leite et al, 2017). However, studies aimed at analyzing the addition of glycerin in swine nutrition, considering its digestibility (Gallego et al, 2014;Madrid et al, 2013), are of paramount importance.…”

-The objective of this study was to determine the nutritional value of glycerin for pigs using different inclusion levels of this test ingredient and the methodologies of total collection and chromium oxide marker. Eight barrows were distributed individually into metabolic cages, in a randomized-block experimental design, and fed diets containing 0, 50, 100, and 150 g kg −1 plant-derived crude glycerin. The feed digestibility methodologies of total feces and urine collection and chromium oxide marker were analyzed. Inclusion of up to 150 g kg −1 crude glycerin improved the digestibility coefficients of organic matter and energy of the diets. The collection method based on the use of chromium oxide marker underestimates the digestibility coefficient of ash and the energy values of glycerin in relation to the total collection method, but yields similar results to those obtained with the total collection method for the dry matter, organic matter, crude protein, ether extract, and neutral detergent fiber assessed.

“…Verussa et al (2017) suggested that a reduction of circulating cholesterol and triglyceride levels could happen due to the replacement of the glycerin in corn diets, thus reducing substrate for the synthesis and transport of fatty acids by liver. However, these authors found no difference in cholesterol and plasma triglyceride in growing pigs receiving up to 15% of soy oil semi-purified glycerin.…”

-The objective of this study was to evaluate performance and carcass and meat characteristics of finishing pigs fed diets with different levels of glycerin, while maintaining the electrolyte balance. Forty barrows with an initial weight of 97.76±13.44 kg were distributed, in a randomized block design, into four treatments with five replicates. Treatments consisted of diets containing 0, 5, 10, and 15% glycerin. Inclusions of salt and sodium bicarbonate were adjusted to balance the sodium content and maintain the same electrolyte balance of the diets as a function of glycerin inclusions. In vivo backfat thickness, daily feed intake, daily weight gain, and feed conversion were measured. After the animals were slaughtered, pH and temperature were measured 45 min and 24 h postmortem, and backfat thickness, loin-eye area, drip loss, and colorimetry were determined. Glycerin inclusion levels did not influence the performance of barrows. Hot carcass weight, dressing percentage, and lightness had higher values when pigs were fed diets containing 2.32, 2.43, and 2.61% glycerin, respectively. The other carcass and meat characteristics were not influenced. Glycerin can be used in finishing pig diets without compromising results of performance or carcass and meat characteristics up to the inclusion level of 15%.

“…Insulin is a hormone whose levels usually increase after feeding to provide energy to the cells, decreasing blood glucose levels. However, no effect of crude glycerin on blood glucose or insulin concentration was observed in piglets [ 10 ] growing [ 41 ] or finishing pigs [ 3 , 42 , 43 ]. Ghrelin, in turn, is a fast-acting hormone that increases appetite so it is also known as the “hunger hormone”.…”

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.
