RODRIGUEZ, Janhad L et al. Contents of anti-nutritional factors in grains of new sorghum cultivars harvested at two vegetative stages and in two seasons of the year. Cuban J. Agric. Sci. [online]. 2015, vol.49, n.4, pp.529-533. ISSN 0864-0408.

Randomly selected grain samples from new sorghum cultivars (CIAP MC-04-12 and CIAP 132-05) harvested in different seasons of the year and at different vegetative stages in 2011 and 2012, were used for determining the contents of phenolic compounds (condensed tannins, total phenols, non-tannin phenols and tannin phenols), β-glucans, phytic acids and cyanogenic glucoside. Results demonstrated that the sorghum cultivar, the vegetative stage and the harvesting season of the grain influenced on the studied concentrations of anti-nutritional factors (ANFs). Tannin phenols in the grains were from 2.6 (CIAP MC-04-12) to 2.8 (CIAP 132R-05) times higher in the dry season regarding the rainy period. Condensed tannin concentrations represented 87 % of the tannin phenols, while the concentrations of β-glucans were from 2.7 to 4.8 times higher (P < 0.001) in the treatments based on CIAP 132R-05 than on those of CIAP MC-04-12.  It is concluded that the two cultivars studied are low in all ANFs.  This suggests a low effect of these ANFs on nutrient digestibility, energetic content and productive performance of monogastric animals receiving diets in which the grains of these cultivars are the main energy source
