  • Sixteen Friesian Cows were allocated equally into 4 groups in a $4{\times}4$ Latin square design to evaluate the effects of utilizing bean by-products on the feed intake and milk production. Cows were fed on 4.5% of their body weight fresh alfalfa; the remainder of their requirements were covered by one of 4 experimental concentrate treatments: 1) commercial concentrate (CC), 2) 70% CC + 30% bean hulls (BH), 3) 70% CC + 30% Polished bean (PB) and 4) 70% CC+ 15% BH + 15% PB. Results showed that the inclusion of bean hulls at 30% improved (p<0.05) milk yield, 4% fat corrected milk yield, feed conversion ratio and fat percent of the milk over the other treatments. Feeding cows on a commercial concentrate plus 30% BH or 30% PB or 15% from each of BH and PB decreased the cost of feed per kg milk by 13.6, 2.5 and 1.3 %, respectively, lower than those fed on the commercial concentrate.

  • This study was performed to evaluate the planting properties of herbaceous plant and cool-season grass in porous polymer blocks that were manufactured by using recycled coarse aggregates and unsaturated polyester resin to develop environmentally friendly planting blocks. Unsaturated polyester resin, natural and recycled coarse aggregates and $CaCO_3$ were used. The mix proportions were determined to satisfy the requirement for the workability and slump according to aggregate sizes(5-10 and 5-20mm). Tests for the void ratio and compressive strength of porous polymer concrete were performed at curing age 7 days. Also, porous polymer block using recycled coarse aggregates were applied to kinds of plants such as tall fescue, Perennial ryegrass, Lesedeza and Alfalfa. After seed, initial germination, germination ratio, cover view and growth length for planting blocks were estimated by various methods.

  • A virus which induced yellowing, vein banding and ruffling on pepper in the field was investigated. The virus reacted strongly with PVY - antiserum in ELISA, but not with antisera of cucumber mosaic virus, tobacco mosaic virus, tomato black ring virus, alfalfa mosaic virus, tomato spotted wilt virus, tobacco etch virus, pepper mottle virus, and tobacco ringspot virus. Electron micrographs revealed that the virus was a flexuous rod of 750-760nm in length. The virus was transmitted mechanically and by Myzus persicae in a nonpersistent manner. The host range was similar to that of PVY, except that Chenopodium amaranticolor and C. quinoa were infected systemiclly.

  • A macerating technique which can apply to the mechanical production system of the agricultural by-product was developed to increase the utilization of agricultural waste and solve the shortage problem in the forage supply for the livestock production. The macerating method is to shred the agricultural by-product by the two rolls which rotate at different speeds each other. The testing macerator was built and the optimum operating conditions are suggested. Results of this research are as follows: 1. The increase of the base roll speed and speed ratio between two rolls shows the better shredding index but decrease the drying rate. The optimum conditions of the base roll speed and the speed ratio between two rolls for the rice straw are 1200 rpm and 1.7-2.0 respectively. 2. The macerated alfalfa was dried to the 15%(w.b.) within 3 hrs in a field at speed ratio of rolls, 2:1 and base roll speed, 1800rpm. 3. The milled surface and straight knurled surface for the macerating roll have same effect on the drying rate of material. Both rolls have self-cleaning functions during operation.

  • Fresh sprouts such as alfalfa, mung bean, radish, broccoli, and soybean sprouts have become very popular due do their high nutritional value. However, there have been several outbreaks of illness in the last few years that have been attributed to sprout consumption. A number of methods have been used to improve the safety of seed sprouts. One promising technology is the use of ionizing radiation treatment. Irradiation with doses up to 8 kGy has been approved in the USA to control microbial pathogens in seeds intended for sprout production. This review focuses on the potential use of ionizing radiation in reducing the pathogen levels in seed sprouts. The effects of irradiation on seed germination and the nutritional quality of the sprouts are discussed.

  • An expreiment with non-nodulating alfalfa (Medicago sativa L.) plants was designed to investigate the changes in protein contents and the activities of proteolytic enzymes during a regrowth period of 24 d. Shoot removal caused a depression of root growth and significantly reduced protein contents in roots. An initial decline of root proteins for the first 10 d was followed by a rapid recovery from d 11 to 24. The major increase of regrowing shoot weight occurred also from d 11. The activities of aminopeptidase and endoprotease slightly decreased in regrowing leaves, while protein contents remains stable after shoot removal. Roots exhibited source behaviour with a rapid increase of endoprotease activities for the first 10 d of regrowth; about a 370% increase over the initial level was observed. Increase in endoprotease activity in roots coincided with the time of protein remobilization after shoot removal, indicating the important role of endoproteases in protein degradation.

  • The DNA fragment containing ginseng ribulose-1,5-bisphosphate carboxytase/oxygenase large subunit(rbcL) gene was cloned from the ginseng chloroplast EcoRl library by colony lift hybridization with tobacco rbcL gene probe. From the screened clone, the DNA fragment containing ginseng rbcL gene was digested with several restriction enzyme and analyzed by Southern blot hybridization for the construction of restriction map. The ginseng rbcL gene fragment was subcloned in pBluescript II SK + vector and sequence analysis was performed. The nucleotide sequence of ginseng rbcL gene was compared with those of petunia, tobacco, alfalfa, rice and barley, which showed a homology of 93.1%, 95.2%, 90.5%, 85.5% and 84.3%, respectively.

  • This study was conducted to investigate the antioxidant contents and activities of twelve vegetable sprouts (broccoli, red radish, radish, mizuna, kale, taatsai, pak choi, Chinese cabbage, turnip, rapeseed, chicory, and alfalfa). The total flavonoid contents of the broccoli, red radish, and radish sprout were $25.36{\pm}0.13$, $25.26{\pm}1.80$, and $25.16{\pm}1.25mg$ CE/100 g FW, respectively, and were significantly higher than those of the other tested vegetables. Radish sprouts had the highest total phenolic content (112.42 mg GAE/100 g FW), followed by red radish and broccoli sprouts. The main polyphenols in the vegetable sprouts were epicatechin and chlorogenic acid, but they varied across sprout varieties. The correlation between total flavonoids and total phenolics for the 12 vegetable sprouts was very high (r=0.926). The total antioxidant activity (DPPH and ABTS radical scavenging activities) was also highly correlated with total flavonoids and total phenolics.
