VAZQUEZ, Ysnagmy et al. Effect of distillers dried grains with solubles on the morphometric of the gastrointestinal tract and internal organs of growing rabbits. Cuban J. Agric. Sci. [online]. 2016, vol.50, n.2, pp. 267-271. ISSN 2079-3480.

A total of 56 growing rabbits (Black Aztec x Chinchilla) from 40 days of age were used in order to study the effect of including 0, 10, 20 and 30 % of distillers dried grains with corn solubles on the morphometric of the gastrointestinal tract ( GIT) and internal organs in a diet based on sorghum-soya. At the end of the fattening (56 days), 32 rabbits were slaughtered (eight per treatment) and the stomach full and empty, caecum and intestines were weighed, as well as the internal organs liver and spleen, all expressed as absolute weight(g), relative weight (g g^-1) and metabolic weight (g g 0.75^-1). With 30 % of distillers dried grains with corn solubles the higher weights  of the stomach full and empty, absolutes (93.75 and 33.75 g), relatives  (4.54 and 1.58 g) and metabolic (0.31 and  0.11 g g0.75^-1) were obtained. There were not differences in the relative weight and metabolic weight of the liver and spleen. It is concluded that the morphometric of the gastrointestinal tract and internal organs of rabbits is not affected with the inclusion of up to 30% of distillers dried grains with corn solubles
