(6(4):1-6)EXPERIMENT ON THE LEUCAENA SEED MEAT INSTEAD OF SOYBEAN OIL CAKE AS PROTEIN SUPPLEMENT FOR HOGS

本試驗應用銀合歡種子經加水煮沸、脫殼、水洗、晒乾後之種子肉代替大豆餅為蛋白質補充飼料，其與大豆餅進行比較試驗之結果，兩組斷乳豬其平均體重達90公斤所需要期間均為160天。銀合歡組與大豆餅組之生長速度相近似。飼料利用效率銀合歡組較大豆餅組為高，但其差異不明顯。至於兩組之屠宰率亦以銀合歡組較大豆餅組為高，然其兩者整異亦不顯著。在試驗期中銀台歡組豬隻健康情形良好而無任何中毒現象。由此可證明經處理後之銀合歡種子肉之營養價值，可以完全利用為代替大豆餅以飼養豬隻。 The farmers in Taiwan have been used the Leucaena seed as feed for hogs. The bad results such as causing vomiting, red skin in appearance, and hair lossing have been reported The use of the meat of the Leucaena seed as a vegetable protein supplement after cooking de-shelling and washing processes for hogs has been observed by Lee et al (1955). The result has shown very good as to the growth rate, daily gain and economy of feed utilization etc. And in the observation period the hogs did not show any ill effects. This experiment has been carried on from Jan. first to Jun. 13th of 1956. Ten hybrids (Berkshire ♂ × Native ♀ and Yorksire ♀× Berksire ♂ ) were divided into two lots, five per lot. The averaged initial weight of the weaning pigs was 14.22 kgs. in the Leucaena seed meat lot, and was 13.82 kgs. in the Soybean oil Cake meal lot (Check lot). The protein level of two lots during the experimental period about the same. The final weight of 90 kgs both the Leucaena seed meat lot and Check lot required 160 days. The averaged daily gain of the two lots were the same was 0.476 kgs. The averaged feed utilization of the Leucaena seed meat lot was 4.114 and of the Check lot was 4.184. The Leucaena seed meat lot was slightly better in feed utilization than that of Check lot, but no significant differences was observed. The averaged dressing percentage of the Leucaena seed meat lot and soy bean oil Cake meal lot were 78. 816and 77. 761 respectively but also shown non-significance between the two lots
