Abstract
This study was conducted to determine the feed value of total mixed rations (TMR) containing different winter forage crop silages on feed intakes, daily gain, nutrient digestibility, and nitrogen retention in Korean black goats. A total of 12 male goats were used in this study and each goat was housed in individual metabolism crates. The treatments were four diets, consisting of whole crop barley silage (T1), rape silage (T2), rye silage (T3), and Italian ryegrass silage (T4). The experiment was designed as a $4{\times}4$ Latin square arrangement in three replicates. Daily intakes for dietary dry matter (DM), organic matter (OM), crude protein (CP) per head were highest in rape silage treatment, and lowest in whole barley silage (p<0.05). Digestible intakes for CP and acid detergent fiber were highest in rape silage treatment. The daily gain of rape, rye, and Italian ryegrass silages were significantly (p<0.05) higher than that of whole crop barley silage. Digestibility of DM. CP, fiber were highest in whole crop barley silage, and lowest in rape silage (p<0.05). Nitrogen (N) intake and N retention were significantly highest in rape silage and lowest in whole crop barley silage (p<0.05). The results showed that, among different winter forage crop silages, rape silage incorporation into TMR had the best performances indicating increases of feed intakes and N retention in Korean black goats.
