Abstract
Experiments were conducted for 4 or 8 weeks to examine the nutritive value of succinic acid and di-ethyl succinate as energy source for poultry. At the dietary level of 5% or lower, response of the chicks to succinic acid corresponded exactly with its caloric value, i. e. 2.99kcal/g and no more, suggesting that succinic acid is hopeful as energy source if the price be reasonable economically.
Succinic acid at the dietary level higher than 5% and di-ethyl succinate at 5% level retarded the growth of chicks significantly, mainly due to poor appetite.
