This experiment was conducted to study the effects of various levels of dietary calcium (1.75%, 2.25%, 2.75%, 3.25% and 3.75%) on laying performances. Experiment was carried out with 1500 White Leghorn layers for a period of 22 weeks. The results obtained are summarized as follows. 1 . Egg production rate and feed. efficiency were significantly (p$lt;0.05) improved as the calcium level of diet increased, however, there were no significant differences between 3.25% and 3.75% of calcium level in egg production rate and feed efficiency. 2. Average egg weight was not influenced by the levels of calcium in the diets. 3. Ratios of egg shell thickness and shell weight to egg weight were significantly (p$lt;0.05) increased as the calcium level of diet increased, however, there were no significant differences in egg shell qualities between 3.25% and 3.75% of calcium level. 4. No difference was found either in calcium and phosphorus contents of tibia or in nutrient utilizability of experimental diets. However, calcium utilizability was highest at 2.75% of dietary calcium level. Based on the above results it may be concluded that the laying performance and feed efficiency could be improved by increasing the calcium level in diet up to 3.25%.

Adult single comb white Leghorn roosters were used to measure the effect of the level of feed input feeding methods as force feeding and intake restricted free feeding and on true metabolizable energy (TME) value of corn. The level of feed input as corn was ranged from 10g to 50g by 10g increments. Unfed birds were used to measure the FEm + UEe loss for each experiment. The results obtained were summarized as follows: 1. Gross energy voided as excreta from fed birds tended to increase in a linear manner as the intake of corn increased. 2. Mean metabolic fecal and endogenous urinary energy (FEm + UEe) and nitrogen excreted from unfed birds were 7.021±0.328 ㎉ (3.628 ㎉/㎏ BW/24hr.) and 0.4488 (0.232g/㎏ BW/24hr.), respectively. 3. The mean THE value of corn was 3.551 ㎉ (per g. of air dry basis) 4. Total gross energy intakes of force-feeding birds and free-feeding birds were 117.300 ㎉ and 112.217 ㎉ per bird. 5. Gloss energy excreted from force-feeding and free-feeding birds were 18.936 ㎉ per bird. 6. The THE value of corn was similar in force-feeding and free-feeding as 3.557 ㎉/g. and 3.549 ㎉/g., respectively. It was concluded that the THE value of corn was not affected by the level of feed input as corn and the optimum level of feed input as corn was 30-40g when the assay bird was an adult S.C.W.L. rooster. And the free-feeding method was more convenient than force-feeding method by eliminating difficult problem such as force-feeding.

This experiment was conducted to study the effect of breed and sex of assay bird on true metabolizable energy value (TME) of corn with adult S.C.W.L. and broiler chicks of male and female, respectively. And unfed birds were used to measure metabolic fecal and endogenous urinary energy (FEm+UEe) excreted. There were 5 replication per treatment including unfed group of birds. The results obtained were summarized as follows. 1. Gross energy excreted was the highest in broiler male chicks as 27.988㎉ and was the lowest in broiler female chicks as 21.164㎉ (p$lt;0.01). However, there were no significant differences among breeds and sexes of assay birds, respectively. 2. No significant differences were shown (p$lt;0.01) among breeds and sexes although FEm+UEe loss of unfed birds were the highest in broiler male clucks. 3. Gross energy excreted per ㎏ body weight of unfed birds tended to decease as body weight of assay birds increased. The value was the highest in S.C.W.L. male as 5.029 ㎉ and the lowest in broiler male chicks as 4.058 ㎉. But there were no significant differences among breeds and sexes, respectively. It was concluded that the breed and sex of assay birds did not affect the THE value of corn and mean THE value of corn was 3.412㎉ (per g. of air dry matter).

Single Comb Brown Leghom male chicks were used to measure the effect of age of assay bird on true metabolizable energy (TME) value of corn, by 6 weeks interval from 8 to 26 weeks old, and were used to measure metabolic fecal and endogenous urinary energy (FEm+UEe) excreted from unfed birds at each age of birds. There were 7 replications. The results obtained are summarized as follows. 1. Gross energy values excreted from fed birds were significantly decreased (p$lt;0.05) as age of bird increased from 8 week to 14 week, although feed energy intakes as corn were almost similar in all ages of birds. 2. Metabolic fecal and endogenous urinary energy (FEm+UEe) values and nitrogen excreted per ㎏ body weight from unfed birds decreased as age of bird increased, but were similar between 20 and 26 weeks old birds. 3. The T M E value of corn in ㎉/g. of air dry matter was the lowest at 8 week old birds as 3.379±0.030 in compare with other ages of buds (p$lt;0.01), however, T M E values were similar among ages more than 14 weeks old. 4. The relationship between body weight(X) and gross energy(Y) excreted per ㎏ body weight of unfed birds was Y=10.607-2.798X (p$lt;0.01). 5. The mean THE value of corn was 3.468㎉(per g. air dry matter).

In order to compare the utilizability of calcium and phosphorus from locally produced tricalcium phosphate (TCP) with that of the imported TCP, dicalcium phosphate (DCP) or bone meal when fed with small amount of fish meal 360 broiler-type chicks of one day old were used for 6 treatments consisted of Control Ⅰ, Control Ⅱ, Imported TCP. Local TCP, Improted DCP and Bone meal group. The results obtained during 5 weeks of experimental period are summarized as follows. 1. It was found that; the body weight gain for birds received various sources of inelegancies phosphates was significantly (P$lt;0.05) higher than for birds received no phosphate or 4% fish meal (Control Ⅱ group). Control Ⅱ group also gained more body weight than Control Ⅰ group. Feeding local tricalcium phosphate, imported dicalcium phosphate and bone meal could significantly (P$lt;0.05) Improved the feed efficiency. 2. It was evidenced that feed intake for Control Ⅰ group was significantly (P$lt;0.05) depressed than for other groups. Although no statistical significances were found among other treatments, the amount of feed intake were tended to increase by the use of calcium phosphate supplements. 3. No difference was observed in nutrient utilizabilities either among treatments or between control and treated groups. 4. The tibia ash. content of broilers fed control Ⅰ diet was significantly (P$lt;0.05) lower than that of others. It was also found that tibia ash content of broilers fed control Ⅱ diet was higher than that of control Ⅰ group. Calcium and phosphorus content of tibia was also higher for the broilers fed various phosphate supplements than control groups as was shown in the case of tibia ash content. 5. Present data indicated that the mortality of broilers during experimental period increased as the level of phosphorous in diets decreased and Ca : P ratio was widened. The results obtained from the present experiments showed that the feeding value of locally produced tricalcium phosphate was comparable to that of imported tricalcium phosphate in body weight gain, feed efficiency, mortality and tibia content of ash, calcium and phosphorus.

This experiment was conducted to compare the nutritive values of limestone, calcitic limestone, and oystershell with a total of 1200 White Leghorn layers. The results obtained during 22 weeks of experimental period are summarized as follows. 1. The calcium contents of oystershell, limestone and calcitic limistone used in this experiment were analyzed to be 29.46%, 34.87% and 38.46%, respectively. 2. Different source of calcium in laying hen diets had no apparent effects on the egg production rate, average egg weight and feed efficiency. 3. The eggshell thickness w-as significantly (p$lt;0.05) different among groups fed different calcium supplements. The eggshell thickness of oystershell, limestone and calcitic limestone fed group was 0.359㎜, 0.346㎜ and 0.339㎜, respectively. The ratios of eggshell weight to egg weight were also significantly (p$lt;0.05) different among treatments in the same trend as the eggshell thickness. 4. There were no significant differences among treatments in contents of calcium and phosphorus of tibia and in the nutrient utilizability of experimental diets. The results obtained from the present experiment showed that the nutritive values of limestone and calcitic limestone were not much different from that of oystershell except in egg shell qualities. It is suggested that all three calcium supplements could he used as good calcium sources in laying hen diet.

This experiment was conducted to investigate the effect of restricted feeding of pullets during the growing period on subsequent laying performance and costs and returns, and was carried out with Hi-sex strain Single Comb White Leghorn chicks with 20 weeks of age in the laying period. The results obtained are summarized as follows. 1. The rate of hen day egg production after the initial delay in sexual maturity was slightly higher for the restricted groups than for the control groups, the total number of eggs laid per bird housed for 294 days test period however, was slightly lower than for the control birds. But there ware no significant differences between control (A) and restricted birds. 2. It was found that the restricted feeding has no difinite beneficial effect on egg size although the restricted birds laid more heavier eggs (0.4-1.1 g) than control group (A). 3. The restricted feeding during the growing did not cause a subsequent increase in total feed consumption in the laying period. Feed efficiency during the laying trial period tended to be related with egg production and egg weight since there were not differences in feed consumption among treatments, but were not significant differences. 4. In the laying period, there was higher mortality in severely restricted birds in the feeding trial than in control birds (A). Larger groups in mortality were D and G group to be 10% and the difference between control and two groups was 4%. But there were no differences between other restricted birds and control birds. 5. No significant differences were found in nutrients utilizabilities of laying hen among treatments. Therefore, it appeared that restricted feeding during the growing period has no effect on nutrients utilizabilities of subsequent laying period. 6. Total feed cost in restricted groups for the both growing and laying periods combined was less than that of control (6996.1 Won) and was the lowest in G group (6612.8 Won). Egg income (7431.6 Won) from the control birds was higher due to total eggs laid when the egg income was estimated by the same size but in case of being estimated by graded size, the egg income from restricted groups except for two groups (B and C) were apparently increased. In this experiment, the most advantageous restricted group was E (80% of intake consumed by control bird). It was concluded that intake restricted feeding during the growing period of pullets would be a desirable and economically more advantageous method for rearing egg production stocks than balanced diet and ful-fed feeding or protein restricted feeding.

This experiment was carried out to investigate the effect of restricted feeding of pullets during the growing period on growth rate, development of oviduct and tibia. The experiment was conducted with 480 Hi-Sex strain of Single Comb White Leghorn pullets with 8 weeks of age during the feeding trial. The results obtained are summarized as follows. 1. Body weight gain was significantly (p$lt;0.05) reduced as the level of protein and feed intake decreased. Feed consumption in protein restricted groups was also significantly (p$lt;0.05) reduced in comparison with that of control groups (A). Feed efficiency however, was not coincided with body weight gain or feed consumption, birds of 80% of intake consumed by control birds during phase 1 (8-14 weeks) and 60% during phase 2 (14-20 weeks) were the highest to be 6.25, and were the lowest in birds (D) fed 10% of dietary protein in both phase to be 8.59. Therefore, there were highly significant (p$lt;0.01) differences in feed efficiency among treatments. 2. Development of oviduct was retarded by restriction of protein and/or feed intake. The length (55.9cm) and the weight (27.8g) of oviduct for the control birds (A) were the highest and the lowest in G (60% of feed intake consumed by control birds in both phase) measured to be 14.9cm and 3.4g, respectively. Therefore, there were significant (p$lt;0.01) differences in the length and the weight of oviduct among treatments of 20 weeks of age. Tibial development was in agreement with that of oviduct but, there were no significant differences. 3. There was higher mortality in severely restricted birds (D and G) than in control birds. Mortality was the largest in the birds of D group to be 8.3%, and the difference between control and D group was 5%. 4. Nutrient utilizabilities of growing chicks were slightly higher in restricted group than in the control group, but there were no significant differences among treatments. It was concluded that body weight gain and development of oviduct and tibia were affected by the degree of restriction, but feed efficiencies in restricted groups were relatively larger than that of control group (A).
