In order to determine the feeding value of t:1e waste wood of Lentinus eddodes, the waste wood was milled and treated with $Ca(OH)_2$ and cellulase, then raw waste wood and the treated waste wood were fed to broiler chicken and Korean native goates. The results obtained were as follows; 1. The chemical composition of the waste wood was c. protein 2.26%. c. fat 2.57%. c. fiber 44.60 and c. ash 5.58%. No differences were detected between the raw waste wood and $Ca(OH)_2$ or cellulase treated waste wood in chemical composition. 2. In amino acid composition. no cystine and methionine was showed, but trace amount of Vitamin A, $B_1$, and $B_2$, and cholin chloride were detected. 3. Trichoderma viride SANK. No. 16374 was used to decompose the cellulose. 4. In broiler performance, when waste wood meal was subsituted for 5% wheat bran, no adverse effect was showed on weight gain, feed in take and feed efficiency. But $Ca(OH)_2$ and cellulase treated waste wood meal could be subsituted for 8% wheat bran. 5. In Korean native goat performance, feeding waste wood meal subsituted by 50% various bran (25% defatted rice bran and 25% barley bran) had no adverse effect on growth and feed efficiency. 6. Considering the above results, though the waste wood meal could be replaced to part of various bran, there was a bottle-neck to process the waste wood. The waste wood of Lentinus edodes was little feeding value on bed of ruminant.

As a series of the research for converting animal excreta into feedstuffs, feed substitutes by fermenting cattle waste was processed as follows: Active Dry Yeast and Yellow Koji were purchased at market, from which strains were separated. Dried cattle wastes mixed with same amount of corn flour were boiled with steam, inoculated with Active Dry Yeast and Yellow Koji, fermented at 30℃ for 48 hours and then dried in shade. In order to observe the optimum level of this feed substitute for mixed brans (barley bran and wheat bran was mixed at same rate in weight), 16 heads of rearing fattening piglets (12 of Landrace and 4 of tri-hybrids) were fed 4 different levels of experimental feed, such as 0, 10, 20 and 30 % by weight, for 4 months. The results obtained were summarized as follows: 1. Active Dry Yeast was classified as Saccharomyces cerevisiae and Yellow Koji as Aspergillus oryzae. 2. One gram of experimental feed was contained 5 to 6 × 10^9 cells of yeast. 3. Comparing the contents of raw cattle waste, the fermented experimental feed was shown increasing value of crude protein, crude fiber and crude ash while nitrogen free extract was decreased. 4. Fermented cattle waste contained more amino acid than that of raw material, especially lysine, methionine, histidine and arginine were doubled. 5. The weight of raw material was reduced by 5 - 6% during the process of fermentation. 6. During the first half period of fattening, substitution with experimental feed showed no bad effects upon fattening up to 30%. However 20 or 30% substitution of experimental feed showed remarkable decreasing value of body weight gain (p$lt;0.01) during the later half period of fattening. 7. No significance difference was observed in the amount of feed intake among the experimental lots. This seem to he that the fermented cattle waste had fair palatability for pig. 8. 10% substitution of experimental feed was observed better feed efficiency than that of control, bat 20% or 30% substitution was worse than control. Considering the above results, the fermented cattle waste could be substituted for various bran during the first period of fattening up to 30%, and later half period by 10%.

This study was performed to affirm any effects of methylthiouracil and estradiol 17β-cypionate administered to young bulls for short term fattening. Eighteen bulls of Korean native breed, approximately 1.5 to 2 years of age and 260㎏ to 360㎏ in weight, were used in this study. All bulls had received a basal ration of soiling corn and concentrate made up of 55% grains, 40% brans and 5% others, in a period of 40 days. Bulls were divided into six groups as follows: group C was not treated, group M-2 received 2g of methylthiouracil per day, group M-3 received 3g of methylthiouracil per day, group EM-0 was injected intramusculary with 25㎎ of estradiol 17β-cypionate in the neck region 10 days after the beginning of the fattening period, group EM-2 was injected with estradiol 17β-cypionate as above mentioned and simultaneously received 2g of methylthiouracil per day, and group EM-3 was injected with estradiol 17β-cypionate as above mentioned and simultaneously received 3g of methylthiouracil per day. The results obtained were summarized as follows. 1. The average daily gain was for group C: 0.83㎏, group M-2: 1.07㎏, group M-3: 1.40㎏, group EM-0, 0.93㎏, group EM-2: 0.95㎏, and group EM-3: 1.18㎏. The M-3 group gained significantly(P$lt;0.05) more weight than C and EM-0 group. There were no significant differences in the average daily gain between the groups injected with estradiol 17β-eypionate and the control group. 2. The average daily concentrate intake was as follows: group C: 5.47㎏, group M-2: 5.00㎏, group M-3: 4.52㎏, group EM-0: 5.21㎏, group EM-2: 4.35㎏, and group EM-3: 4.61㎏. The consumption of concentrate was decreased by 17% in the M-3 group compared with the C group. There was no significant difference in the soiling corn intake among these groups. 3. Feed consumed for 1㎏ gain were decreased by the supplementation of methylthiouracil. The consumption of DCP for 1㎏ gain was in group C: 0.82㎏, group M-2: 0.59㎏, group M-3: 0.41㎏, group EM-0: 0.70㎏, group EM-2: 0.59㎏, and group EM-3: 0.50㎏. The amounts of TDN required were; group C: 6.57㎏, group M-2: 4.76㎏, group M-3: 3.39㎏, group EM-0: 5.67㎏, group EM-Z: 4.87㎏, and group EM-3: 4.08㎏. The consumption of DCP and TDN for 1㎏ gain in the M-3 group was about a half of that in the C group. 4. There was not any significant difference in the increase in body measurements among the various groups. 5. The average margins in the fattening period of 40 days were for group C: 2,950won, group M-2: 5,327won, group M-3: 9,158won, group EM-0: 3,310won, group EM-2: 3,623won, and group EM-3: 5,575won. The margin of group M-3 was about three times higher than that of group C. In short, this experiment demonstrated that methylthiouracil when fed to young native Korean bulls at the proper level 40 days before slaughter would bring a noticeable effect on weight gain, feed efficiency and economic advantage. There were no advantages from the simultaneous injecting estradiol 17β-cypionate with methylthiouracil. The proper supplementation level of methylthiouracil would appear to be 3g per head per day in this experiment.

The effects of hexestrol dicaprylate (HESC) implantation on rate of gain and economic feed utilization were studied. Ten Korean native yearling bulls and a corresponding number of controls were used in this experiment. All animals were fed a fattening ration of soiling corn and concentrate made up of 50% corn, 48% brans and 2% others for 105 days. Implanting with 100㎎ of HESC increased rate of gain by 0.6%. Feed required per 1㎏ of gain was decreased by the implanting of HESC. Implanting with HESC increased rate of nutrient utilization for 1㎏ of body gain by 6.6% DCP and 6.9% TDN. No undesirable effects was noted in the experiment.

The effect of hexestrol dicaprylate implantation on the rate of gain of Aberdeen Angus(♂)×Korean native cattle (♀) F₁ steers were studied. Three steers were implanted with 100㎎ of hexestrol dicaprylate and 3 steers was not treated. All steers grazed native pasture with feeding supplements for 105 days. The average daily gain of the hexestrol implanted steers were more by 9.5% than that of the controls. However, there was no significant difference in daily gain between the groups. The daily gain in the present study were found to be less than that of the young bulls of Kim, et al. (1971). No undesirable side-effects such as development of mammary gland resulted from hexestrol implantation.

This experiment was carried out in order to investigate the nutritive value of rice straws, which were produced by inoculated with the isolate of Pleurotus Ostreatus SACCARDO. A feeding trial was conducted for 4 months to evaluate the feeding value of either raw rice straw or Pleurotus Ostreatus SACCARDO treated rice straw for growing fattening calves. Eight Korean native steer calves were randomly assigned into 2 groups according to their age and body weight. The obtained results were summarized as follows. 1. The rice straw inoculated with isolate of Pleurotus Ostreatus SACCARDO increased significantly (p$lt;0.01) about 40% in crude protein contents from 3 weeks after the treatments, and increased slightly in crude ash, but crude fat decreased significantly (p$lt;0.05) and the other ingredients showed some decrease in contents. 2. Lignin contents of treated rice straw decreased little by little as the time elapsed but there was no any significant decreases in this experimental period. 3. The treated rice straw was consumed a little less in quantity than raw rice straw. 4. During the experimental period, the average total body weights gain of calves which were fed with the treated rice straw was 92.50㎏, while that of calves fed with raw rice straw was 91.25㎏. 5. As for the amount of feeds required per l㎏ of body weight gain, in treated rice straw plots calves consumed 3.23㎏ of concentrate and 3.82㎏ of treated rice straw and in the raw rice straw plots calves consumed 3.25㎏ of concentrate and 4.22㎏ of raw rice straw, so that a better feed efficiency was showed in the treated straw.
