畜試所開發樹薯粉碎糙米混合飼料 可替代75%飼料玉米

Quick Look

農業部畜試所將樹薯粉與公糧碎糙米按1:2比例混合,開發出可替代75%飼料玉米的離乳豬飼料配方。雖成本略高,但豬隻採食量、日增重、飼料利用效率與健康狀況無差異,具高度替代可行性,有助降低對進口玉米依賴並提升糧食安全。

AI-generated summary

Why It Matters

臺灣飼料主要原料玉米幾乎全依賴進口,易受國際地緣政治與氣候變遷影響導致價格波動,畜試所致力開發可替代飼料玉米的替代原料以降低風險。

國內飼料主要原料之一的玉米幾乎全部都倚賴進口,為開發更多可替代玉米的原料,農業部畜試所團隊將樹薯粉與公糧碎糙米用一比二的比例混合後,成功開發出可替代75%飼料玉米的離乳豬隻替代配方,雖成本略高,但豬隻飼養品質仍穩定。

進口玉米常因國際地緣政治變化與氣候變遷價格波動,畜試所尋找可替代進口玉米的飼料原料,該所團隊選擇具高澱粉熱能的樹薯與蛋白質及胺基酸含量較豐富的糙米,透過體外澱粉消化率試驗,調配出最佳的1:2混合比例,以克服樹薯澱粉較難消化及蛋白質不足之特性,該所在4週齡離乳豬進行為期4週的測試,發現用樹薯粉混碎糙米粒方式可取代75%的飼料玉米,並且豬隻採食量、日增重與飼料利用效率與健康等都和飼料玉米沒有差別。

請繼續往下閱讀...

畜試所進一步指出,進口飼料級樹薯乾片每公斤約12元,公糧撥售碎糙米則約每公斤8.325元(以美國玉米高雄港大盤均價9.25元/kg9折計算),兩者1:2混合原料成本每公斤約9.55元,替代75%玉米後,配合飼料成本分別較未取代組每公斤增加約 0.225元,畜試所表示,樹薯粉與碎糙米混合原料飼料成本略高,且目前仍有仰賴進口及供應量較低等限制,但仍具高度替代可行性,也可配合政府雜糧轉作政策及活化休廢耕農地,更能因應進口大宗穀物供給風險,建構我國糧食安全防線。

Insects are scarce during the flowering period of Gaoping candied dates. Worry about production reduction and price increase

Candied dates in the Gaoping area have entered the flowering stage, but due to the heavy rains in the south for nearly a month, the number of pollinating insects such as bees, butterflies, and flies has been greatly reduced, resulting in poor pollination. Farmers are worried that the fruiting rate will decline, the output may be reduced this year, and the price may rise before the Spring Festival. Currently, artificial pollination can only be strengthened to reduce losses.

Harvesting is in progress at Gansu Jiuquan Flower Seed Production Base, with an annual output of up to 15 million kilograms.

The 119,500 acres of flower seed production fields in Jiuquan City, Gansu Province have entered the intensive harvesting period, with an annual output expected to reach 15 million kilograms. Herbaceous flower seed supply accounts for 70% of the country, and exports account for half of the country. It benefits from sufficient sunshine and wide day and night temperatures. The seeds are irrigated by poor, lack of rain and snow water from the Qilian Mountains. The seeds are separated by space to prevent powder contamination. After harvesting, they undergo deep processing and quality testing such as air sorting and color sorting to achieve a purity of 95%. Preparations are currently being made for export, and the customs has set up a green channel to improve customs clearance efficiency.
