“…Papadomichelakis et al (2015) concluded that feeding CG at 7% level improved the feed efficiency in broilers but did not affect the growth rate. Further increase in CG to 10 to 21% affected the bird's performance, feed intake and increased the water intake which affected litter quality (Cerrate et al, 2006;Papadomichelakis et al, 2015). Loose litter quality may result in coccidiosis and mortality.…”

Increased concern on greenhouse gas emission, concomitant global warming and decreasing fossil fuels have created the necessity to find an alternative source of energy for the transportation vehicles. Biodiesels is an alternative renewable fuel source, which releases less carbon dioxide, carbon monoxide, sulfur and nitrogen oxides upon combustion. These environmental friendly features of biodiesel make it a potential alternative to the conventional one. Biodiesel can be extracted from the edible or non -edible source of triglycerides. During this extraction process, crude glycerol (CG) is obtained at the rate of 10% as a byproduct of trans-esterification reaction. Chemically, CG so obtained is composed of catalysts, salts and fatty acids. Purification of CG to >95% involves the cost (0.28 USD/L production) and time consuming process. Hence, economical management of CG is the need of hour, one such alternative way is its entry in animal food chain as an energy source. Basically, glycerol is a glycogenic intermediate product of fat digestion converted to glucose by the action of key enzyme glycerol kinase. The CG undergo glycolysis and TCA cycle to liberate ATP. The digestible and metabolizable energy content of CG are comparable with the commonly used cereal grains in livestock feeding. Thus, CG acts as a bridging gap between the biodiesel industry and livestock production. Studies have showed that CG

The objective metrics to evaluate changes in the components of the intestines of broilers fed the diet with the addition of crude glycerin to 7% and to compare the dimensions of these components in the different intestinal portions. This research was carried out in the experimental shed in XXXXXX the poultry sector were selected 16 animals randomly, and these were divided into two groups, one without crude glycerin added to the feed (A), and another with the addition of crude glycerin to feed (B). The animals were fed until 46 days of age, were subsequently euthanized and samples taken from the duodenum jejunum and ileum for histomorphometric assessment and comparison between groups between intestinal portions. Histomorphometric evaluation of the small intestine of the two groups showed a significant difference only in the duodenum, where there was a reduction of villi length in the treatment with the addition of crude glycerin to 7% (172,08 x 132,12 µm; control and treated group, respectively). When comparing the size of the mucosa of the components of each intestinal portion was observed a gradual reduction of villi and crypt and the muscular wall in the cranio-caudal direction. It is concluded that the addition of glycerin in broiler diet reduces the duodenum villus length and the dimensions of the components of the intestinal mucosa decrease in the cranio-caudal direction intestine.
