| 中文摘要 | 本研究評估熱季於環控鵝舍調控降溫系統及馬達安裝變頻器對舍內環境參數、鵝隻生長、屠體性狀、鵝舍電力消耗、用水量和二氧化碳排放量的影響。環控鵝舍尺寸為600 × 337平方公分,每個欄位配備了一個水簾和一個風扇。96隻5週齡白羅曼鵝分成處理組和對照組,處理組鵝舍配置之風扇、水簾馬達安裝變頻器,降溫系統控制條件為舍內溫度達25℃或相對濕度達60%或氨氣濃度達0.5 ppm,風扇以50%效能(30赫茲)運轉;舍內溫度達27℃或相對濕度達70%或氨氣濃度達1.0 ppm,風扇以100%效能(60赫茲)運轉;舍內溫度達29℃水簾啟動。對照組配置之風扇及水簾馬達無安裝變頻器,控制條件為舍內溫度到達25℃啟動風扇,並以100%效能運轉,溫度達29℃啟動水簾。試驗為期8週(自2024年7月3日至8月26日),期間記錄鵝舍環境參數、鵝隻體重、採食量、鵝舍用電、用水量及鵝隻屠體性狀等。結果顯示,處理組二氧化碳濃度較對照組低,但氨氣濃度高於對照組。處理組鵝隻血液中總蛋白質濃度顯著高於對照組。試驗全期之鵝隻體重、採食量、體增重、飼料轉換率及13週齡屠體性狀於兩組間均無顯著差異。此外,處理組較對照組減少9.4%用電量及134.23公斤碳排放量。本試驗結果顯示,環控鵝舍透過降溫系統調控及馬達安裝變頻器,能有效節省電力並降低溫室氣體排放。 |
| 英文摘要 | The study evaluates the variations of indoor environmental parameters, goose growth, carcass traits, electricity consumption, water usage, and carbon dioxide emissions in environmentally controlled goose houses with cooling system regulation and motor variable frequency drive (VFD) installation during the hot season. The pen size of closed cooling pad house is 600 × 337 cm^2, with equipping a set of cooling pad system and fan per pen. 96 five-week-old White Roman geese were divided into the treatment and control groups with four repetitions. The difference between two groups was the motors of fan and cooling pad system were equipped with VDF in treatment group, while the control group was not. Three experimental conditions were set in the treatment group. The fan was turned on and set to operate at 50% efficiency (30 Hz) when the temperature reached 25°C, or relative humidity reached 60%, or ammonia concentration reached 0.5 ppm; while the temperature reached 27°C, or relative humidity reached 70%, or ammonia concentration reached 1.0 ppm, it was set to operate at 100% efficiency (60 Hz). When the temperature exceeded 29°C, the cooling pad system was activated as well. Two set up conditions were applied in control group. The fan was turned on and ran at 100% efficiency when the temperature reached 25°C, then the cooling pad system was switched on when the temperature exceeded 29°C. The entire experiment period was from July 3 to August 26, 2024. The records included environmental parameters of the goose house, geese body weight, feed intake, carcass traits, electricity and water consumption of the goose house were collected. The results showed that the carbon dioxide concentration in the treatment group was lower than that in control group, while the ammonia concentration was higher. The total protein concentration in blood of geese in the treatment group was significantly higher than that in control group. Throughout the trial, there were no significant differences between the two groups in body weight, feed intake, weight gain, feed conversion ratio, or carcass traits at 13 weeks of age. Additionally, the treatment group reduced electricity consumption by 9.4% and carbon emissions by 134.23 kg compared to control group. Our results demonstrate that cooling system regulation combined with motor VFD installation can effectively save electricity and reduce greenhouse gas emissions. |
