This experiment was conducted to increase the nutritive value of perilla meal and to investigate the presence of the growth inhibiting factor in the meal. The first feeding test was carried out with F₁ chicks between W. Rock and W. Cornish which were fed the diets containing 0, 15, 20 and 25% of perilla meal from one day to 4 weeks of age. And two types of perilla meal treated by dry autoclaving at 15 p.s.i. for 30 min. were also fed at 20% level of diet, respectively. The second feeding test was carried out with S.C.W. Leghorn which were fed the diets containing 0, 15 and 25% of perilla meal for 3 weeks. Each perilla meal treated as follows was added into the diets at level of 25%. 1. autoclaved at 15 p.s.i. for 30 min. and washed with water. 2. autoclaved 15 p.s.i. for 30 min. and unwashed. 3. boiled for 30 min. and washed. 4. Soaked with tap water for 8 hrs. and washed. Each experimental diet was prepared to be isonitrogenous and isocaloric. The experimental results obtained were as follows: No significant difference was found in body weight gain between chicks fed no treated high level of perilla meal and fed control diet in both experiments. Although, no significant difference was observed in feed efficiency between chicks of each levels of perilla meal, feed efficiency was decreased as the level of perilla meal was increased. In test Ⅰ, dry autoclaving of perilla meal gave no effect on weight gain or feed efficiency of chicks. In test Ⅱ, the treatments of wet autoclaving, boiling and water soaking of periila meal following washing, respectively, decreased weight gain of chicks compared with that of control group. But chicks fed perilla meal treated by autoclaving-unwashed was increased weight gain more than that of control group with no significant. Decrease in nitrogen retention percent was observed among the groups fed perilla meal at levels of 15 and 25% of no treatment and treated by autoclaving-washing or water-soaking-washed, and these were significant at 5% level. It can be concluded that there is no growth inhibiting factor in perilla meal because chicks fed high levels of perilla meal showed normal growth and fed various physical treatments of perilla meal gave no increase in weight gain.

The experimental objectives were to observe the feeding and economic value different grower feed, that is, commercial diet, high fiber diet, low lysine diet, low lysine-low protein diet during the growing period and also for the effect on the lad ing performance in semi-broiler breeder. The results obtained were as follows; 1. On the body weight gain and feed efficiency during the growing period, all experimental groups were responded favorably over the control group and especially low lysine B and low lysine-low protein B groups were improved 15% in weight gain and 12% in feed efficiency over the control group. 2. On the age at sexual maturity, all experimental groups were delayed for a period of 1-2 weeks. 3. As for the egg production and production efficiency during the laying periods, low lysine A and B groups were very favorably responded over the control, compared to that of other experimental groups. 4. The analysis on the economic return indicates that the return for all experimental groups was greater than that of the control the best economic return attained was for the low lysine B group with an increase of 15% over the control group.

These experiments were conducted to study on the interrelationship between Cu & Zn and the effect of dietary copper sulfate on the growth of broiler chicks. The experimental trials were composed of two parts. For the experiments, a broiler type chicks, cobb and starbro, were raised for a period of four weeks from the day of hatching, involving 9 to 8 different dietary treatments. The results obtained from these studies are summarized as follows; 1) Addition of 100 to 150 ppm dietary copper significantly(p$lt;0.01) improved the rate of growth and the feed efficiency of chicks. At the level of 150ppm copper added, the weekly weight gain of the experimental chicks was improved by 28% over that of the control group. 2) Inclusion of dietary copper excess of 600ppm was resulted in a deterioration of the growth, exerting a copper toxicity, but this was corrected by the addition of dietary zinc, indicating the presence of an antagonistic interrelationship of copper with zinc. 3) Such antagonistic relationship of copper with zinc was further evidenced by the analysis of copper and zinc retained in the chick liver as shown in figure 1.

To determine the effects of dietary levels of hydrocarbon grown yeasts on the growth, feed efficiency, blood uric acid content of broiler chicks and also on the metabolizability of the yeast. tile feeding experiments were ran for a period of 14 weeks. The results obtained are summarized as follows: 1. In the body weight gain, feed intake and feed efficiency n-paraffin-grown yeast (wash) group was superior to that oP either gas oil or n-paraffin grown yeast (solvent) group in the preliminary trial. 2. It was observed that neither the weight gain nor the feed efficiency was significantly different among the experimental groups including the control. 3. The metabolizable energy of both gas oil and n-paraffin grown yeast were determined as 2374 ㎉/㎏ and 2742 ㎉/㎏ respectively. 4. The differences in nutrient availability and the results of carcass analysis were not statisticaly significant among the experimental groups. 5. Serum uric acid was shown to be higher as to increase the level of yeast but differences were not significant up to 12% level compared to that of control, but the group receiving 15% level resulted in twice of that control value. Red blood cell was lower as to increase the level of yeast added in the ration.

An experiment was conducted employing 36 Landrace × Yorkshire crossbred weighing an average of 23 ㎏ to evaluate the nutritive value of Canadian rapeseed meal for growing-Finishing swine. Shown below are the results obtained. (1) Crude protein content of the rapeseed meal studied was 34.4% and the amino acid composition of the meal was similar to the previously reported data. (2) Pigs fed either 5 or 10% of rapeseed meal consumed less feed and gained less weight than those fed the control diet. Improvement of feed efficiency was demonstrated by rapeseed meal fed pigs. Differences in feed intake and feed efficiency were significant (p$lt;0.05). (3) The results of digestion and balance trials indicated that protein digestibility and nitrogen retention of diets including rapeseed meal were slightly lower than the control diet without any statistical significance. (4) The protein of rapeseed meal was 67.8% digestible and the values of total digestible nutrients(TDN), and digestible energy(DE) were 60.8% and 2,703 ㎉ per ㎏ as fed, respectively. (5) It appeared that the growth depressing effect of rapeseed meal accounted for the low palatability of the meal rather than the previously reported toxic effect. (6) Pigs fed rapeseed meal yielded less percentage of live weight as carcass, but produced carcasses with thinner backfat than those fed control diet.

Studies were conducted to improve the nutritive value of wasted human-hair collected at barber shops as a feed ingredient for poultry. The results were summarized as follows: 1) Pepsin digestibility of human-hair waste in vitro is greatly enhanced by the treatment with dilute alkali. The digestibility of hair protein after the treatment was 90%, and this was far better effective than autoclaving methods to improve the digestibility of hair protein. 2) After the alkali treatment, there are changes in amino-acid compositions compared to that of prior treatment. Aliphatic amino acids of serine and threonine were greatly reduced after the treatment while little changes were observed for the essential amino acids of methionine and lysine. 3) The feeding trial indicates that up to 4%, the treated hair meal could be added in to replace soybean meal or fish meal or both in an isonitrogenous basis without exerting any adverse effects on the growth.

The main objectives of this experiment were to determine the nutritive value of the ensilaged corn-starch pulp and also to demonstrate the economy of using the ensilage as a feed ingredient to replace wheat at 5 percent level for the broiler production. For the experiment, a broiler-type chicks, welpline 220, was raised for a period of four weeks from the day of hatching involving a total of 192 chicks and six different treatments, Results obtained from present study are summarized as follow; 1) For the experimental group, the starch pulp was replaced with wheat at 5 percent level on a weigh to weight basis. 2) The weekly weight gain for the group of ensilaged starch pulp fed was improved by 10-20% over the control group with a statistitical significance at 5 percent level. However for the feed efficiency, the differences between the values of the control and experimental groups are shown to be not significant. 3) On the contrary, the addition of raw starch pulp for the place of wheat is poorly responded to the ckicks and this is resulted in better growth for the control, indicating that raw starch pulp itself is deteriorating the feed value. Through the processes of ensilage, the nutritive value of starch pulp can be improved and the activity of micro-flora of ensilaged products is apparently responsible for the cause. 4) The unit price of the feed required per kilogram of weigh gain is less for the ensilaged group of 104.8 won compared to the control group of 108.0 won, suggesting that the ensilaged starch pulp can be added to replace wheat at a five percent level for the economy of broiler production.
