中文摘要 | 以4 週齡白羅曼鵝144 隻逢機分為4 處理組,每組4 重複並分二期,進行馬鈴薯與甘藷補充飼糧試驗。試驗前期:於鵝隻4 - 8 週齡進行。4 處理組包括:正對照組,以一般生長鵝料任食; 負對照給飼試驗飼糧,每日限飼170 g/隻;馬鈴薯或甘藷補充組,如負對照組限飼170 g/ 日/ 隻,再分別額外補充馬鈴薯或甘藷任食。試驗後期:8 - 13週齡,各組均給飼一般生長鵝料( 同試驗前期對照組) 任食。結果顯示,試驗前期:額外補充甘藷組的總飼料攝食量為351.0 ± 27.5 g/ 日/ 隻 (mean ± SD) 與正對照組相近,且顯著高於負對照組與補充馬鈴薯組(P < 0.05),表示甘藷的適口性優於馬鈴薯。試驗後期: 任食期間各組的飼料消耗量以負對照組最高為387.1 ± 29.6 g/ 日/ 隻,補充馬鈴薯組次之為379.1 ± 25.5/ 隻,此兩組的體增重顯著高於其它兩組(P < 0.05),顯示試驗後期的肉鵝有代償性生長的現象。就試驗全期而言,負對照組的飼料消耗量(290.6 ± 16.5g/ 日/ 隻) 顯著低於其它3 組 (P < 0.05),表示試驗前期給予限飼可降低飼料總攝食量。體增重則以正對照組最高為3.44 ± 0.23 kg/ 隻,顯著高於負對照組的3.06 ± 0.04 kg/ 隻 (P< 0.05),顯示雖然適當的限飼條件須再探討。額外補充馬鈴薯與甘藷組的體增重,分別為3.23 ± 0.16 與3.29 ± 0.16kg/ 隻,與正對照組間無顯著差異。綜合以上顯示,限飼再額外補充馬鈴薯或甘藷的給飼方法,對肉鵝而言,似乎為一可行的方式。 |
英文摘要 | A total of 144 geese at 4 weeks of age were randomly allocated into 4 groups to evaluate the method of supplying potato and sweet potato on growing geese. For 1st period, between 4 and 8 weeks of age, treatments were positive control group, giving growth diet ad libitum; negative control group giving experimental diet 170 g/day/goose restriction; two supplying groups were 170 g/day/goose restriction same with negative control group and supplying potato and sweet potato ad libitum at the same time, respectively. For 2nd period, all groups were giving same growth diet ad libitum between 8 and 13 weeks of age. The results of 1st period showed that the feed consumption of supplying sweet potato group was 351.0 ± 27.5 g/day/ goose (mean ± SD) which was closed to positive control group and significantly (P < 0.05) higher than those of negative control and potato supplying groups. It means that the palatability of sweet potato was better than potato for geese. At 2nd period, the highest feed consumption was in negative group 387.1 ± 29.6 g/day/goose and the supplying potato group was the next. And the body weight gain (BWG) of these two groups were significantly higher than those in the other two groups (P < 0.05). It means that the compensatory growth appeared at 2nd period. For whole period, the feed consumption of negative control group 290.6 ± 16.5 g/day/goose was significantly lower than those of the other 3 groups (P < 0.05). But their BWG 3.06 ± 0.16 kg/goose was significantly lower than positive control group 3.44 ± 0.23 kg/goose (P < 0.05). It means that the restriction method can reduce total feed consumption, but the suitable restriction conditions need further study. However, this supplying method may be useful for feeding domestic geese. |
