Objectives : The purposes of present study were to identify weight increment in female psychiatric patients during hospitalization and to evaluate the relationship between weight gain and daily calorie intake, daily activity and other variables of disease itself. Methods : 20 patients were studied. Body weight were measured once a week, and daily activity(total amounts of walking/day) and total amount of daily calorie intake were measured twice a week. We examined psychiatric and medical illness history, eating disorders' history and family history of eating disorders and obesity. Results: Mean body weight and Body Mass Index(BMI) at admission are 49.40kg and 19.59kg/$m^2$. Mean weight increment during hospital stays of mean 65 days is 4.90kg. Mean amounts of daily calorie intake and daily activity(daily walks) were increased during hospital stays, but not statistically significant. The degree of weight increment is higher in longer hospital stay group, but not statistically significant. Mean body weight at admission of mood disorder group is higher than that of schizophrenia group, but not statistically significant. Conclusion : This results suggested that weight increment in female psychiatric hospitalized patients is present. However, it is not resulted by amount of calorie intake and daily activity level.

This study was conducted to evaluation the effects of dietary soybean meal (SBM) and fermented soybean meal (FSBM) on the growth performance of Korean native cattle as Hanwoo calves (Bos taurus coreanae) and Holstein cows. In total, 16 calves three to four months old (Control group, SBM: 5 males and 3 females, average weight 105.7 kg; Experimental group, FSBM: 5 males and 3 females, average weight 103.7 kg) were fed 5% of the feed amount for 53 days. In terms of growth performance outcomes, the average gain body weight was significantly higher in the FSBM group than in the SBM group in the final fattening period. The average daily gain in body weight (ADGBW) for the FSBM group was higher than that of the SBM group in the final fattening period. The average gain body weight in four months for FSBM was higher than that at three months in the final fattening period. Diarrhea incidence for FSBM was significantly decreased compared to that in the SBM group in the six-week period after weaning. These results indicate that dietary FSBM can improve the growth rate and health condition during the calving period. Holstein cows fed fermented soybean meal had higher milk urea nitrogen levels and decreased somatic cell counts compared to those fed SBM. These results may be closely related with the increased average daily gain body weight associated with dietary FSBM.

Two experiments were conducted to subdivide isoleucine (exp. 1) and valine (exp. 2) requirements for maintenance from the requirements for growth of broilers aged 1 to 3 weeks. Purified diets were used, containing five graded levels of isoleucine and valine. Based on weight gain response, the isoleucine requirement for growth was 7.50 mg/g weight gain and the daily isoleucine need for maintenance (mg) was 0.044 per unit metabolic body size ($(Wg^{0.75})$). Based on the N gain response, the isoleucine requirement for growth was 0.317 mg/mg N gain and the daily isoleucine need for maintenance (mg) was 0.040 per unit metabolic body size $(Wg^{0.75})$. Based on weight gain and N gain response, the total isoleucine requirement was calculated 244 mg/day or 0.59% of the diet, 274 mg/day or 0.66% of the diet, respectively. From the relationship of weight gain and N gain, 5.07% of the retained protein was comprised of isoleucine; the reported isoleucine content of chick muscle was 4.42%. The valine requirement for growth was 9.84 mg/g weight gain and 0.36 mg/mg N gain whereas the maintenance requirement was 0.046 or 0.052 mg per unit of metabolic body size (Wgo.11. According to the model developed to estimate valine requirement, the total requirement was 319 mg/day or 0.77% of the diet, 315 mg/day or 0.76% of the diet, respectively. Previous reported valine requirements for growing chicks of 7~24 days old were in close agreement with these estimates. As a percentage of retained protein, valine was calculated to be 5.81% ; the reported valine concentration of crude protein of chicks' body including feathers was 6.72%.

Growing and finishing Korean native bulls were used to investigate the effects of different dietary energy levels on performance and energy intake. Experimental observations were made over three weight categories (200 to 250 kg, 250 to 350 kg and 350 to 450 kg). Three diets (2.4, 2.6 and 2.8 Mcal ME/kg DM) were used for each weight category. Crude protein levels of the diets were 12, 11 and 10% for the respective weight groups. Dietary energy level did not significantly affect daily body gain within a weight range but daily body gain during the entire experiment was higher (P<.05) in bulls receiving 2.6 Mcal energy diet than in those fed 2.4 and 2.8 Mcal energy diets. The following equation was developed to predict daily body gain(Y) from energy levels(X) of ration. $Y\;=\;1.3.475X\;-\;2.5949X^{2}\;-\;16.355$ Increasing energy levels significantly (P<.05) decreased daily feed intake. The following equation was developed to predict daily feed intake(Y) from energy levels(X) of ration. $Y\;=\;-30.013X\;+\;5.4401X^{2}\;+\;49.119$ Feed intake per metabolic body size during the entire feeding period ranged from 100.9 to 110.8 g and was lower in bulls fed 2.6 and 2.8 Mcal energy diets than in those fed 2.4 Mcal energy diet. Increasing energy levels significantly (P<.05) improved feed efficiency. The following equation was developed to predict feed efficiency(Y) from energy levels(X) of ration. $Y\;=\;-118.34X\;+\;22.448X^{2}\;+\;162.85$ Daily energy intake during the entire experiment ranged from 18.90 to 19.99 Mcal and there was no significant difference among energy levels. Daily energy intake per metabolic body size during the feeding period ranged from 248.6 to 260.8 kcal and was slightly higher in bulls receiving 2.8 Mcal than in those fed 2.4 and 2.6 Mcal energy diets. Energy required per kg body gain ranged from 17.25 to 19.11 Mcal and was slightly lower in bulls receiving 2.6 Mcal energy diet than in those fed 2.4 and 2.8 Mcal energy diets.

The effects of daily feeding frequency (Exp I), water temperature (Exp II), and stocking density (Exp III) on the growth of river puffer, Takifugu obscurus, juvenile fish of 10 and 40 g in body weight were examined to develop effective techniques to produce river puffer in a non-exchange water system. In Exp I, fish were fed commercial floating feed with 45 % protein one to five times per day to apparent satiation each by hand daily for 8 weeks at $25^{\circ}C$. In both the 10- and 40-g size groups, the final body weight, daily feed consumption, and weight gain of fish fed one meal per day were significantly lower than those of fish fed five meals per day (P < 0.05). However, there were no significant differences in the final body weight, daily feed consumption, and weight gain among fish fed two, three, and five meals per day. Feed efficiency showed decreasing tendency with increasing size of fish. In Exp II, fish of 10 and 40 g in initial body weight were reared with the commercial feed at $15-30^{\circ}C$ for 8 weeks. The weight gain of fish increased with raising water temperature up to $25^{\circ}C$ and decreased drastically at $30^{\circ}C$ for both sizes. The Q10 of specific growth rate was decreased with raising water temperature from 5.04 (temperature interval, $15-20^{\circ}C$) to 0.66 ($25-30^{\circ}C$) for the 10-g fish and from 4.98 to 0.31 for the 40-g fish. In Exp III, the effect of stocking density on growth was examined with fish of 10 and 40 g in initial body weight. The final body weight for initial stocking densities of 4, 8, and $12kg/m^3$ was significantly higher than that of $20kg/m^3$ for the 10-g fish, and the final stocking density reached 10.1, 19.2, 28.7, and $39.9kg/m^3$, respectively. For the 40-g fish, the final body weight for initial stocking densities of 3 and $6kg/m^3$ was significantly higher than that of 9 and $15kg/m^3$ and the final stocking density reached 7.38, 13.5, 17.1, and $27.5kg/m^3$, respectively (P < 0.05). In both groups, weight gain tended to decrease with increasing stocking density; however, survival showed no significant difference.

Purified diets containing five graded levels of tryptophan were fed to growing chicks to evaluate tryptophan requirements for growth and maintenance. A model was developed to separate tryptophan requirement for maintenance from requirement for growth. From this model, the daily tryptophan requirement for growth was 2.16 mg/g gain, and the daily requirement for maintenance 0.029 times metabolic body size ($Wg^{0.75}$). Based on nitrogen gain response, the tryptophan requirement for growth was 0.078 mg/mg N gain, and the daily maintenance requirement was 0.029 times metabolic body size. The total tryptophan requirements were 71.56 mg/day or 0.173% of the diet, 69.48 mg/day or 0.168% of the diet based on the weight gain response and nitrogen gain response, respectively. Previous tryptophan requirements for growing chicks aging 1-28 days are in close agreement with these estimates. Based on the relationship of weight gain and N gain, about 1.25% of the retained CP was consisted of tryptophan; the previously reported value of tryptophan content of chick muscle CP was 1.03%.

The Hinai-dori is a breed of chicken native to Akita Prefecture, Japan. An $F_2$ resource population produced by crossing low- and high-growth lines of the Hinai-dori breed was analyzed to detect quantitative trait loci (QTL) for growth traits. Highly significant QTLs for body weight at 10 and 14 weeks of age and average daily gain between 4 and 10 weeks and between 10 and 14 weeks of age were accordingly mapped in a common region between ADL0198 and ABR0287 on chromosome 1 and between MCW0240 and ABR0622 on chromosome 4, respectively. A significant QTL for body weight at 4 weeks of age and a significant QTL for average daily gain between 0 and 4 weeks of age were mapped for the first time to the same region flanking ABR0204 and ABR0284 on chromosome 1. These QTLs are good candidates for application in the development of marker-assisted selection strategies for increasing growth efficiencies in the Hinai-dori breed and native breeds of chickens in Asia.

본 연구는 3년산 북방전복의 해상가두리의 먹이공급비율에 따른 성장 및 생존율을 조사하여, 미역과 다시마등의 천연먹이의 적정 공급율을 제안하여 북방전복 성패의 생산성 향상을 유도하고자 실시하였다. 먹이공급율은 실험전복 어체중량을 기준으로 일간공급율 (daily feeding rate, DFR) 5, 10, 15, 20% (5 DFR, 10 DFR, 15 DFR, 20 DFR) 를 설정하여, 해상가두리에서 2반복으로 13개월간 실시하였다. 해상가두리에서 사육한 전복 (최초 수용 시 평균각장 $73.77{\pm}11.27mm$) 성장에서 각장과 각폭의 성장율 (growth rate, GR), 일간성장율 (daily growth rate, DGR) 및 특수생장율 (specific growth rate, SGR) 과 체중의 증중률 (weight gain, WG), 일간증중률 (daily weight gain, DWG) 및 특수증중률 (specific weight gain, SWG), 그리고 생존율에서 5 DFR이 유의적으로 높았다 (P < 0.05). 생존율은 모든 실험구가 유의적 차이가 없었으며, 30%이하로 나타났다. 따라서 3년산 북방전복을 해상가두리에서 사육 시 미역, 다시마 등의 생먹이의 일간 공급율은 어체중량의 5-10%에서 공급되는 것이 성장에 유리하지만, 생존율을 향상 시킬 수 있는 다각적 검토가 필요하다.

Data spread over 11 years (1986-1996) pertaining to a synthetic population developed by inter se mating of half-breds of Corriedale and Russian Merino with Nali maintained at CCS Haryana Agricultural University, Hisar were utilized for the estimation of genetic parameters for growth traits. The means for birth weight (BWT), weaning weight (WWT), six month body weight (SWT), yearling weight (YWT), preweaning daily gain (PRW) and post weaning daily gain (POW) were 3.35 kg, 10.79 kg, 13.28 kg, 18.96 kg, 82.6 gm and 27.6 gm, respectively. The effects of year and season of birth and sex of lamb were significant for all the traits under study except the effect of season of birth for WWT, SWT and PRW. No definite trend was observed over the years for the averages of body weight and gain. Lambs born during the spring season performed better for BWT, WWT and PRW while the performance of lambs born during autumn was better for the other traits included in the study. The male lambs were heavier than the females for body weight at all stages and gain in weight. The heritability estimates for WWT and PRW were low; for BWT and SWT were moderate and for YWT and POW were high. Birth weight had high heritability and high genetic correlations with subsequent body weights and gains but due to the presence of a maternal effect on BWT and WWT, a sequential selection procedure is recommended for the improvement of growth rate in sheep.
