(4(3):1-12)A Study on Sesbania Sesban Merr. (No. 2) Seed as Protein Supplement for Livestock

1．關於處理方法，據本試驗結果，以化學及微生物併用法爲最優，玆將其處理程序列下：田菁元粒壓扁→加5~6倍水，待沸騰后將田菁投入，煮沸10分鐘濾過→加5倍之1% HCl液，浸60分隱過→加10倍水，浸60分濾過。加2%食鹽混和，放置1~2日使之醱酵後，乾燥。 2．處理后田菁組成(表格略) 3．處理后田菁中之特殊成分(表格略) 4．處理後田菁中之酸度以乳酸表示=0.22% 5．飼料化田菁製成率乾物對乾物=82.9%即純乾物100kg田菁，可製成純乾物82.9kg飼料化田菁。 6．廢液中鹽酸囘收利用 依下列公式，可算出廢液中應添加之HCl量，而使之成爲1% HCl液。 A×B×C=D A=浸酸廢液＋浸水廢液總量 C=1%鹽酸濃度 B=恆數0.8 D=應添加之HCl cc.數 例如10kg沸煮後田菁，浸酸液要50kg，水漬液要100kg，浸酸液吸收20%=10kg，故廢液中只剩40kg，浸水液無變化，故仍舊爲100kg，兩者混合，計成140kg，此值代入上公式：(方程式略) 即加入1120cc. HCl，將140kg，廢液變爲1% HCl液140kg，可供田菁浸酸之用，如是連續使用，不特鹽酸可以囘收利用，且用水液見經濟。 註：浸酸液按田菁重量5倍，浸水液按田菁重量10倍。 7．保存試驗 保仔六個月後，除重量稍增加（約增8.9%，此乃吸收空中濕氣關係）外，其他狀態如發霉色澤及香味等，均無變化。 According to the qualitative and quantitative analysis in previous experiment (see the first report), it is found that Sesbania seed contains special components which have strong physiological effect in livestock and a peculiar odor which makes the livestock refuse to feed. The purpose of this experiment is to find out the way to remove these disagreeable components, and make the seeds be capable of being used as a protein supplement for livestock. The results are summarized as follows: 1) The methods used for processing Sesbania seeds in this experiment are divided into mechanical treatment, biological treatment, chemical treatment, and chemical combine with biological treatment. Among these methods, as it is shown by this experiment, the chemical combine with biological treatment is the best. The procedure of which is written in the following: The seeds are first rolled→5~6 times boiling water is added to the seeds and boiled for 10 mins. then drained-soaking in 1% HCI solution 5 times the volume of seeds for 60 mins. and drained→soaked in water 10 times the volume of seeds for 60 mins. then drained→added 2% common salts to the seeds and exposed in the air for 1-2 days until they are fermented→dried. 2 The composition of treated seeds. (The from abridges) 3) The special components of treated seeds (The from abridges) 4) The acidity of treated seeds as expressed in percentage of lactic acid is 0.22%. 5) About 82.9% product is obtained from the raw Sesbania seeds in dry condition. 6) The drained hydrochloric acid solution may be restored for further use, and the quantity of water used in above process may also be saved economically. In order to make it become 1% HCI solution, hydrochloric acid is added to the drained solution. The amount of which can be calculated by the following formula. A×B×C=D Remarks: A=the total amount of the drained solution and drained water. B=a constant of 0.8. C=1% concentration of hydrochloric acid. D=the quantity of hydrochloric acid added, as expressed in cc. 7) Experiment of preservation. After six months preservation no change (such as moulding, colour, or flavour etc.) was occurred, except a slight increase in weight (about 8.9% it is absorbed moisture from the air)
