中文摘要 | 本試驗目的,在測定?糞乾物等量取代飼糧16%或添加牛脂3%,飼餵肥育後期豬隻對增重、飼料換肉率以及屠體品質的影響。根據供試平均體重48kg之公豬40頭,分為四處理,經飼養60日測定所得結果,其在期末增重、飼料增重比率、屠宰率、屠體長度、背脂厚度、腰跟肌肉面積、後腿、背脊、前腿、肩胛、腹協、四分切、五分切重百分率之平均值,順次(A)單純基本飼糧對照為46.66 kg, 3.154, 71.81%, 81.25 cm, 2.98 cm, 29.20cm2, 22.84%, 17.82%, 12.28%, 6.86%, 17.95%, 59.91%, 77.86%;(B)基本飼糧添加牛脂者為47.28 kg, 3.058, 73.79%, 80.75 cm, 3.00 cm, 28.87 cm2, 21.74%, 18.47%, 11.52%, 6.95%, 18.92%, 58.66%, 77.37%;(C)?糞試驗飼糧者為39.24 kg, 3.713, 71.27%, 75.50 cm, 2.92 cm, 25.17 cm2, 20.16%, 20.41%, 11.86%, 7.34%, 19.68%, 59.76%, 79.44%;(D)?糞試驗飼糧添加牛脂者為 38.82 kg, 3.737, 71.45%, 76.00 cm, 3.13 cm, 21.13 cm2, 22.37%, 20.00%, 13.04%, 6.58%, 17.08%, 61.98%, 79.05%。顯示經飼餵?糞豬隻之增重及飼料利用成績,均較基本飼糧者低劣,且有極顯著之差異,牛脂添加於基本飼糧或?糞試驗飼糧後,對豬隻增重及飼料利用率,與未添加者無差異(P>0.05),至於對豬隻屠宰率及屠體各項性狀,除腰跟肌肉面積,後腿重佔屠體重百分率處理間分別有極顯著及顯著之差異外,其他各項成績,四處理彼此間,差異均不顯著(P>0.05)。供試各處理豬隻屠體依照美國農部所訂標準,均可列入US No.1等級,品質優良。?經飼餵?糞豬隻屠體,並無不良影響。 |
英文摘要 | Study was made to determine the effects of sun-dried chicken manure containing 12% moisture and 22.46% crude protein as substitute for 16% equal weight of feed in finishing diet with or without 3% tallow on growth, feed conversion and carcass quality of the fattening pigs. Forty male crossabred pigs averaging 48kg in weight were divided into 4 treatments on the basis of litter and nody weight of 10 head each treatment. Treatment A received corn-soybean finishing basal diet as control. Treatment B, basal diet + tallow 3%; Treatment C, basal 84% + chicken manure 16%; Treatment D basal 84% + chicken manure 16% + tallow 3%. The pigs were housed on concrete-floored individual pens; diets were given twice daily individually and allowed free access to water at all time. Body weight and feed consumption records of each pig were kept at the intervals of 20 days throughout 60 days of the feeding trial. At the completion of the feeding trial two pigs from each of the four treatments were slaughtered for carcass study. The results were given in tables 3 and 4. It showed that the mean values of weight gains, feed conversion rate of the pigs at the end of the feeding trial, dressing percentage, carcass length, back fat thickness, lean loin eye area, percentage weight of trimmed ham, loin, picnic, butt, belly, 4 lean cuts, 5 primals for the pigs of treatment A were 46.66 kg, 3.154, 71.81%, 81.25 cm, 2.98 cm, 29.20 cm2, 22.84%, 17.82%, 12.28%, 6.86%, 17.95%, 59.91%, 77.86%; of treatment B were 47.28 kg, 3.058, 73.79%, 80.75 cm, 3.00 cm, 28.87 cm2, 21.74%, 18.47%, 11.52%, 6.95%, 18.92%, 58.66%, 77.37%; of treatment C were 39.24 kg, 3.713, 71.27%, 75.50 cm, 2.92 cm, 25.17 cm2, 20.16%, 20.41%, 11.86%, 7.34%, 19.68%, 59.76%, 79.44%; while of the treatment D were 38.82 kg, 3.737, 71.45%, 76.00 cm, 3.13 cm, 21.13 cm2, 22.37%, 20.00%, 13.04%, 6.58%, 17.08%, 61.98%, 79.05% respectively. The data indicated that the growth and feed conversion rate of the fattening pigs were significantly decreased (p<0.01) as the chicken manure was used to replace 16% of ingredient on dry weight basis in the finishing swine diet. The addition of tallow 3% to either the basal control diet or the chicken manure experimental diet did not improve the growth and feed conversion rate of the fattening pigs. However, no detrimental effects were found on their health and carcass qualities from this trial. |
