| 中文摘要 | 探討蘭嶼豬、畜試迷彩豬及商用豬加工特性之差異,以供品牌化之用。試驗分為三組:蘭嶼豬、畜試迷彩豬及LYD 商用豬,其中蘭嶼豬與畜試迷彩豬飼養30 週(開始體重:蘭嶼豬20 ㎏,約18 ~ 20 週齡、畜試迷彩15 ㎏,約16 ~ 18 週齡)後屠宰,商用豬約25 週齡屠宰。屠宰後取得里脊肉、腹脇肉與後腿肉三種部位測定一般肌肉化學組成、蒸煮失重、屠後24 小時保水性、截切值、咀嚼性、ATP 關聯化合物、與感官品評等項目。結果顯示,蘭嶼豬在各部位之水分含量顯著高於畜試迷彩豬與LYD 商用豬(P < 0.05),而在各部位之粗脂肪含量以畜試迷彩豬含量最低(P < 0.05)。蘭嶼豬烹煮失重顯著低於商用豬及畜試迷彩豬(P < 0.05)。蘭嶼豬有較高保水性之趨勢(P < 0.10)。蘭嶼豬截切值、咀嚼性均較LYD 商用豬低。ATP 關聯化合物方面,蘭嶼豬IMP 含量顯著較高(P < 0.05),HX 含量較低;里脊肉及後腿肉之HXR 各組間無顯著差異。在感官品評方面:蘭嶼豬香氣顯著高於商用豬(P < 0.05),氣味以LYD 商用豬有較低之趨勢。LYD 商用豬之里脊肉嫩度較蘭嶼豬低,但腹脇肉部位較蘭嶼豬高(P <0.05)。總接受度以蘭嶼豬和畜試迷彩豬高於LYD 商用豬。 |
| 英文摘要 | The objectives of this study were to understand the effects of irrigation of pig waste water with anaerobic fermentation on forage yield and quality of nilegrass (Acroceras macrun ) and the properties of soil and leaching water. Four quantities of waste water irrigated were equivalent to 400, 600, 800 and 1,200 kg N ha-1year-1, respectively. The electric conductivity (EC), the total N, NH4 + and NO3 - and the dissolved P in leaching water collected at 1 m depth were increased with increasing amount of irrigation. The contents of organic matter, total N, available P, exchangeable K and EC in surface soil increased significantly with the amount of waste water. However, no significant difference was observed in soil pH and the contents of exchangeable Ca and Mg in soil treated with different amounts of waste water. The forage yield and the chemical constituents, i.e., crude protein, ammonium nitrogen, nitrate nitrogen, P and K in the plants increased with the amount of irrigation. However, the ratio of K / (Ca+Mg) didn’t exceed 2.2 and won’t affect animal health, even though the irrigation with the waste water being equivalent to 1,200 kg N ha-1year-1. The contents of inorganic N in the plant grown in the cool season would exceed 1,000 ppm when nilegrass was irrigated with the waste water equivalent to 800 and 1200 kg N ha-1year-1. Based on these results, application of pig waste water with anaerobic fermentation in nilegrass pasture increased forage yield and improved soil fertility. However, the content of inorganic N in nilegrass and the quality of leaching water from soil layers should be monitored after long-term irrigation with pig waste water. |
