Trials have been conducted to determine the acceptability of hydrolyzed leather meal (HLM) in the broiler diets. The results obtained were summarized as follows; 1. The crude protein and ash content of HLM was found to be respectively 66.65 and 14.45 percent. Also, glycine and methionine content was 17.05 and 0.26 percent. 2. There was not significantly difference among the groups in the weight gain, feed intake and feed efficiency. 3. in vico and in vitro protein digestibility were found to be 82.73 and 70.85 percent. 4. Chromium content of HLM was 1.14 percent and chromium in liver and kidney eras higher as to increase level of HLM in formula feed, but there was no apparent accumulation of chromium in muscle to 4 percent level. This results indicate that hydrolyzed leather meal for the place of oil cakes can be used up to 4 percent level in the broiler ration.

The experiments were designed to evaluate nutritive value of whole sweet potato (root to stem and leaf ratio in 3 : 1), being pressed and sun-dried, for the pig grower. The potato was substituted with corn meal at the levels of 0, 10, 20 and 40% on air dried matter basis in the first trial. For the subsequent trial, the substitution level was extended to 60% basis. In the first feeding trial, overall growing performance including weight gain and feed efficiency, and the results of carcass analysis were not significantly different between the control and the potato groups. Nutrient digestibility of sweet potato was, however, inferior to that of the control group. The digestible energy value of potato sample was estimated as 2,678 ㎉/㎏. Contrarily, for the second feeding trial, the of reds of feeding the potato upon weight gain, feed efficiency and nutrient availability were somewhat decreased with increasing the level of potato but little significant difference was attained between the control and the groups of 40% potato feeding. The feed cost required per ㎏ weight gain for the potato groups of upto 40% feeding was tuned cut to be favorable over the control.

This experiment was conducted to study the nutritive value (TDN) of rice straws which were produced by chemical treatment and the fermented methods for cattle and pig. The results obtained were summarized as follows: 1. TDN value of the fermented products of rice straw for cattle was ranging from 50.5 to 58.4%. The value was 10% higher than the one for pig. TDN value of raw straw for cattle was attained as 41.0%. 2. The nutritive value of rice straw with aerobic fermentation after 0.25% Ca(OH)₂-steamed treatment did not improve significantly over the 3% NaOH-steamed treatment. 3. The fermented product of rice straw by Asp-9 resulted in higher TDN value than other strains. 4. It was tested TDN value of rice straws which were produced differently by the fermented methods. The process F-II using Asp-9 resulted in higher TDN value but little significant difference were observed among fermentation methods.

Nutritional aspects deeding the sweet potato, being processed by physical means of pressing and drying, were examined for the place of yellow-corn with chicks. Prior to the feeding trials, chemical compositions including vitamin and mineral contents, and amino-acid profiles of respective potatoes samples were analysed. Metabolizability of experimental samples were also included in this study. 1. For the first feeding trial of broiler starter, potatoes (pressed or not pressed) anal whole potato (root to leaf and stem ratio in 2 : 1 or 4 : 1) were substituted with corn meal at 0, 5, 10, 20 and 30% levels on an air dried weight to weight basis. The weight gain, feed intake and feed efficiency of control group were superior over the sweet potatoes groups and it was observed that the effect of weight gain was decreasing with increasing the substitutional levels of the potatoes in all treatments, but upto 10% substitution levels, little significant difference was observed between control and experiment groups. The metabolizable energy value of potatoes (pressed) and whole potato (root to leap and stem ratio in 3 : 1) were estimated as 2,538 ㎉ and 2,406 ㎉ per kilogram respectively. However, the feed cost required per ㎏. weight gain was less for the 20% (potatoes pressed) and the 10% (whole potatoes) groups compared to that of control. 2. In subsequent feeding trial on the broiler starter. The samples of potato (with or without steamed) were substituted with corn meal at the same levels as was in the first feeding trial. For the weight gain as well as feed efficiency, the potato groups of both with or without steamed was inferior to that of control group but differences were not significant among the groups. The metabolizable energy value of steamed potato was estimated as 3,100㎉/㎏., higher than the pressed one, but the estimated production cost was higher than the control group. 3. As for the starting chicks, the whole sweet potato, being hot sir dried, was substituted with corn meal upto 20% on an air dried weight to weight basis. It was observed that overall growing performance was also decreased with increasing the levels of potato but upto 10% level, little statistical difference was also observed among the roups. 4. In the hen-day egg production, egg weight and feed efficiency, the performence of experimental groups in the first trial were favorable over the control group, and this results indicate that the whole potatoes can be in corporated in laying rations up to 14% in replacing corn, and the substitution of corn with potatoes was also proved to be economically feasible. Such favorable results of feeding the potato for the place of corn was also confirmed by subsequent trial on laying hen.

This experiment was carried out to study the effect of rice straw-manure silage containing ryegrass forage, corn meal, or raw rice bran on the fattening performance of Korean cattle at farm condition. Nine Korean bulls with mean weight of 230㎏ were used for the trial from August, through November 1979 in Ansong villege, Kyong Ki province. The results obtained are as follows 1. Proximate composition, acid detergent fiber (ADF), and hemicellulose content showed little differences between straw-manure silage containing ryegrass forage and corn meal. However, crude protein, crude fat and volatile fatty acid content of straw-manure silage containing raw rice bran was higher than others. Analysis of silage with raw rice bran showed 4.15% of crude protein, 2.74% of crude fat, 1.15% acetic acid and 2.04% of lactic acid. All alkali treated straw-manure silages are high in butyric acid and propionic acid. pH values in the silages with raw rice bran, ryegrass forage and corn meal are 5.42, 5.83, and 5.58, respectively. 2. In the feeding trial, the animals receiving. straw-manure silage with ryegrass forage showed best performance with daily gain of 1.38㎏ arid feed efficiency of 5.51. However, the groups receiving. the straw-manure silage with corn meal or rice bran revealed daily gain of 1.16 or 1.29㎏ while the feed efficiency was 6.54 and 6.04, respectively.

A deoxidized low-phosphorous copper processed by eight cycles of accumulative roll-bonding (ARB) was annealed at various temperatures ranging from 100 to $400^{\circ}C$. The annealed copper was characterized by transmission electron microscopy (TEM) and tensile & hardness test. TEM observation revealed that the ultrafine grains developed by the ARB still remained up to $350^{\circ}C$, however above $400^{\circ}C$ they were replaced by equiaxed and coarse grains due to an occurrence of the static recrystallization. The hardness of the copper decreased slightly with the annealing temperature up to $350^{\circ}C$, however they dropped largely above $400^{\circ}C$. Annealing characteristics of the copper were compared with those of an oxygen free copper processed by ARB and subsequently annealed.

Two experiments were carried out to study the feeding value of barley straw silage for Korean cattle. For the first feeding trial, it was conducted for 100 days to evaluate the growing performance in twenty bulls with 150㎏ body weights and barley straw silage with alkaline treatment was substituted with wheat bran at the level of 10%, 20%, 30% on the dry basis. Far the second feeding trial, it was conducted for 90 days to evaluate the growing performance in 24 bulls with 200㎏ body weights, and barley straw silage was substituted with wheat bran at the level of 20% and 30% on the dry basis. In this trial the alkaline treated straw was once neutralized before the silage. Each experiment also included the treatment which raw barley straw with grinding was replaced for wheat bran at 20% level. The results obtained was summarized as fellows: 1. In the first feeding trial, the barley straw silage group responded favorably over the ground raw straw fed group but shored less body weight gain and the TDN intake was less compared with control group, decreasing as to increase the level of silage incorporation. But it was not significantly differences between control and silage groups. 2. In the second feeding trial, it was resulted in more weight gain and better feed efficiency of the straw silage group over the control (P$lt;0.01). Therefore, the alkaline treated barley straw which was once acid-neutralized before the ensilage was improved over the previous non-neutralized silage.
