中文摘要 | 30頭雜交肉女豬,由體重20 kg單獨飼養至95 kg,以探討六種不同玉米與大麥配合比例(依次分別為100:0、80:20、60:40、40:60、20:80和0:100)對生長肥育豬飼養效果之影響。大豆粕用以調整各種處理組飼料之蛋白質用量,生長期(體重20~50 kg)飼料之蛋白質量為16.8%,當每一頭豬體重達50 kg後改換為14.5%。結果,生長期豬隻飼料中,玉米和大麥使用在100:0與40:60之間的配合比例使豬隻每日增重和飼料換肉率均顯著(P<0.05)或極顯著(P<0.01)地優於0:100者。肥育期豬隻飼料中,玉米和大麥配合比例對豬隻每日增重無顯著的影響,但飼料換肉率則在玉米和大麥使用在100:0與60:40之間的配合比例顯著(P<0.05)地優於0:100者。玉米與大麥使用比例中大麥超過上述適用比例雖有降低豬隻背脂厚度的趨勢,但統計結果差異不顯著。試驗結果顯示,餵給生長期和肥育期豬隻之飼料中可替代玉米的用量分別達60和40%,尚不影響豬隻之增重和飼料效率。同時,大麥適當的應用可使豬隻所需飼料蛋白質來源之大豆粕用量降低2~3%。 大麥餵飼生長期和肥育期豬隻之增重效率分別為玉米的86%和93%。 |
英文摘要 | 30 crossbred gilts were individually fed from 20 kg to 95 kg bodyweight to evaluate the feeding value of different maize: barley ratios (100:0, 80:20, 60:40, 40:60, 20:80 and 0:100, respectively) in growing-finishing pig diets. Soybean meal was used as the sole protein to supplement for adjusting the crude protein level of each diet. The pigs were started on a 16.8% protein diet and switched to a 14.5% when the pigs reached 50 kg bodyweight. During the growing period (20-50 kg) pigs on the maize: barley ratios between 100:0 and 40:60 gained faster and required less geed (P<0.05 or P<0.01) than pigs on the ratio of 0:100. During the finishing period (50-95 kg) pigs on the ratios between 100:0 and 60:40 required less feed than pigs on the ratio of 0:100, but their daily gains were not influenced by these different ratios. When the pigs were fed with diets containing more barley, there was a tendency to decrease backfat but without statistical significance. The results showed that daily gain and feed conversion were not influenced when 60% and 40% of maize in the diets were replaced by barley, respectively, for the growing and finishing pigs. The use of proper amounts of barley required 2-3% less soybean meal supplementation than did maize in order to bring the diets to the same protein content. The feed efficiencies of barley were 86% and 93% as compared with maize in the diets for the growing and finishing pigs, respectively. |
