This experiment was carried out to estimate the nutritive value of mixed-sowing winter forage crop and whole crop barley by investigating the effects of feeding mixed-sowing winter forage crop and whole crop barley in KBG (Korean black goat) on feed intake, average daily body weight gain, nutrient digestibility and nitrogen retention. The 12 male KBG were divided into four experimental groups - i.e. T1: barley silage added group, T2: mixed-sowing hairy vetch silage added group, T3: mixed-sowing field peas added silage, T4: mixed-sowing Italian rye grass added silage group. Three KBG per each treatment were allotted into individual metabolic cages by Latin-square design. The results from this study are as follow. The DMI (dry matter intake) and organic matter intake in T4 were significantly (p<0.05) higher than those in T1 and T3 and crude protein intake in T4 also recorded the highest among treatments (p<0.05). The highest values in intakes of ADF and NDF were observed in T4 followed by T2, T1 and T3 in order. The average daily body weight gains in T4 and T2 were significantly (p<0.05) higher than those in TI and T3. The dry and organic matter digestibility in T2 and T4 were significantly (p<0.05) higher than those in T1 and T3. The crude protein digestibility in T1 was significantly (p<0.05) lower than those in T2 and T4. The nitrogen intakes in T2 and T4 were significantly (p<0.05) higher than those in T3. The results obtained from this study suggested that the feeds supplemented with whole crop barley with hairy vetch and Italian rye grass mixture silage increased KBG productivity resulted from increases in feed intake, nutrient digestibility and nitrogen retention.
