中文摘要 | 本地黑山羊(Na)、努比亞(Na)、F1(Nu×Na)、G1(Nu×F1)、G2(Nu×G1)等五個品種 參與本試驗。在離乳後平均每日之增重比較上,Na、F1、G1與G2各別為0.097±0.4、0.124 ±0.04、0.099±0.03及0.088±0.03公斤,而以F1之增重最佳話P<0.05),四個品種的飼料 利用效率在統計上雖然顯著差異,但仍以F1 及G1有較佳的趨勢.在繁殖效率方面Na、F1、 G1、G2的受胎率分別為83.8%、72.1%、72.5%、100% 及 76.7%,除G2因係均為女羊參 試及頭數較少而致高達100%之外,Na之受胎率最高,但由於努比亞山羊原屬多胎性高之 品種,雙胞胎及三胞胎百分比均高(46.4% 及 32.2%)。雜交級進的結果使F1、G1、G2的產 仔率仍優於本省山羊,屠體性狀調查發現Nu之脂肪率遠高於Na(10.5% vs. 7.1%),F1 則居 中為8.3%,其他在屠宰率與淨肉率等項目則Na、Nu及F1之間無顯著差異。 |
英文摘要 | Post-weaning growth traits, reproductive performanceand carcass characteristics of Taiwan Native goat (Na), Nubian(Nu),F1(Nu×Na), G1(Nu×F1) and G2 (Nu×G1) mere compared' Average daily gain of Na, F1 , G1 and G2 was 0.097± 0.04, 0.124±0.04, 0.099± 0.03 and 0.08± 0.03 kg ,respectively, and the F1 has best performance (p<0.05). No difference was found on feed efficiency among breeds Conception rate of Na, F1, G1, G2 and Nu was 83.8% 72.1%,72.5%, 100%and 76.7%, respectively, Except G2's highest Conception rate fromyoung primiparous does, the Na performed best, In considering kidding rate however, Na, F1, G1, G2 and Nu was 161.3%, 184.9%, 186.0%, 164.3% and 212.1%, respectively, There was no difference on dressing percentage, Nubian's carcass had highest fat percentage (10.5%) when compared with Na's 7.1% and F1's 8.3%, In conclusion, by crossing Nubian to Taiwan native goat, there were improvement in fertility although no advantage in carcass quality. |
