The conclusion of this applied nature study showed that at early stages of plant growth i. e. 3rd leaf stage sorghum cultivars exhibited more HCN contents which could be toxic for the animals and with the advancement of growth stages the HCN contents were reduced. The result of this study showed that pre- booting stage to onward sorghum forage is safer i. e. 25 mg / 100 g from the HCN toxicity and more nutritive to feed animals. Postcutting intervals study showed that the HCN contents were decreased at all intervals but after 12 hours of postcutting intervals to onward maximum HCN...
