You must read this article, if you think that Bio-fuel research is all about finding appropriate biomass like corn grain or soybean oil etc and converting it into fuel. Scientists have discovered environmental and economical benefits of the byproducts of bio-fuel production. Did you know that we can yield approximately two-thirds of a pound of crude glycerin while producing a gallon of biodiesel from soybean. When refined to 99 percent purity, this glycerin can be used medicines, foods, drinks, cosmetics, and toiletries.
Livestock and poultry producers are looking for new sources of feed supplements to save costs and boost nutrition. Animal scientist William Dozier evaluated the use of glycerin supplements in poultry feed as it contains energy-providing nutrients for animals. Dozier dealt with broilers and gave glycerin-supplemented poultry feed to those between age group of 7 to 45 days. He calculated the apparent metabolizable energy (AME) intake for the group under observation and a control group (with regular diet).
The youngest chicks under observation, aged between 7 to 10 days, showed no significant differences in body weight or energy lost excretion (urine and feces). The second group aged between 21 to 24 days also showed insignificant difference in body weight, energy excretion and AME. Except that, their feed intake and the amount of energy provided by the diet intake (gross energy) increased with the increase in glycerin supplements. However, the oldest broilers in age group of 42 to 45 days showed increases in feed consumption, gross energy, and AME.
Dozier noted that this technology could be an alternative dietary energy source to save feed costs among poultry. By supplementing livestock feed with glycerin, the corn grain and soybeans used as livestock feed are now being used for bio-fuel production.
