Sweet Potato as Animal Feed and Fodder

摘要: Alternative sources of livestock feed to spur production and free cereal supplies for human consumption are receiving closer attention. Sweet potato has higher biological efficiency as food shows highest productivity (35-45 t ha -1 ). It relatively short vegetative cycle (4-5 months). Hence, fits nicely into tight cropping systems. also competes better with weeds than other root tuber crops. The DM content sweet varieties ranges from 21.70 34.78% which is more cassava. Its tubers can be given all ruminants fresh, chopped tubers, dried chips silage energy supplements along locally available grasses during the dry season. vine foliage a common pigs, livestock, in many countries, including China, India, Indonesia, Korea, Philippines, Papua New Guinea, Taiwan, Uganda Vietnam protein supplement. skin leaf tips contain comparatively protein, 50-90% 18-21%, respectively. Tubers essential amino acids, exception sulfur-containing especially cystine/cysteine. Digestibility appears problem some that grown under certain types conditions. digestibility carbohydrate fraction reported above 90%. Selections low trypsin inhibitor activities helps expand plant's potential wider use an animal feed. roots good source (3500 kcal kg ) poultry. Main reasons adoption dual-purpose economical viability, net returns crude (CP) fodder.
