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.

Objective: In this study, we aimed to position the Hungarian Merino among other Merinoderived sheep breeds, explore the characteristics of our sampled animals' genetic similarity network within the breed, and highlight single nucleotide polymorphisms (SNPs) associated with daily weight-gain. Methods: Hungarian Merino (n = 138) was genotyped on Ovine SNP50 Bead Chip (Illumina, San Diego, CA, USA) and positioned among 30 Merino and Merino-derived breeds (n = 555). Population characteristics were obtained via PLINK, SVS, Admixture, and Treemix software, within-breed network was analysed with python networkx 2.3 library. Daily weight gain of Hungarian Merino was standardised to 60 days and was collected from the database of the Association of Hungarian Sheep and Goat Breeders. For the identification of loci associated with daily weight gain, a multi-locus mixed-model was used. Results: Supporting the breed's written history, the closest breeds to Hungarian Merino were Estremadura and Rambouillet (pairwise F_ST values are 0.035 and 0.036, respectively). Among Hungarian Merino, a highly centralised connectedness has been revealed by network analysis of pairwise values of identity-by-state, where the animal in the central node had a betweenness centrality value equal to 0.936. Probing of daily weight gain against the SNP data of Hungarian Merinos revealed five associated loci. Two of them, OAR8_17854216.1 and s42441.1 on chromosome 8 and 9 (-log₁₀P>22, false discovery rate<5.5e-20) and one locus on chromosome 20, s28948.1 (-log₁₀P = 13.46, false discovery rate = 4.1e-11), were close to the markers reported in other breeds concerning daily weight gain, six-month weight, and post-weaning gain. Conclusion: The position of Hungarian Merino among other Merino breeds has been determined. We have described the similarity network of the individuals to be applied in breeding practices and highlighted several markers useful for elevating the daily weight gain of Hungarian Merino.

The effect of different feeding rate on the growth and survival rate of 3-year-old abalone, Haliotis dicsus hannai were investigated in marine net cage culture. Feeding rate is determined that was fed 5, 10, 15 and 20 percentage to abalone at body weight once daily : 5 daily feeding rate (DFR), 10 DFR, 15 DFR and 20 DFR. After that, it was conducted to reared during thirteen month with two replicates in net cage culture. In the growth performance of reared abalone (initial mean shell length $73.77{\pm}11.27mm$) in net cage culture, that the absolute growth rate (ARG), daily growth rate (DGR) and specific growth rate (SGR) to the shell length and shell breadth, as well as weight gain (WG), daily weight gain (DWG) and specific weight gain (SWG) to body weight of 5 DFR were higher than those of different groups (P < 0.05). Also, survival rate of all feeding rate groups was not significant, but it was showed bellow 30 percents. Therefore, these results is showed that the daily feeding rate for natural feed of 3-year-old abalones reared in net cage culture should be to supply among five to ten percents.

Birth weight and subsequent weight gain is of critical importance in the survival and performance of piglets on a commercial swine farm setting. Oropharyngeal microbiome could influence immunity, and feeding behavior thus impacting health and weight gain. We used 16S rRNA gene sequencing to profile the composition and predicted metabolic functionality of the oropharyngeal microbiota in 8 piglets (4 with a birthweight ≤ 1.0 kg and 4 with a birthweight ≥ 1.7 kg) at 11, 26, and 63 days of age. We found 9 genera that were significantly associated with average daily gain (ADG) at 11 days (false discovery rate, FDR < 0.05) and 26 days of age (FDR < 0.1), respectively. The microbial functional profile revealed several pathways associated with ADG (FDR < 0.05). Among these, pathways related to degradation of catechols showed a positive association with ADG at 11, 26, and 63 days of age, implying a potential to breakdown the host-derived catecholamines. We also noted that pathways related to the biodegradation of nucleosides and nucleotides increased with ADG during the pre-weaning phase, while those involved in their biosynthesis decreased. Our findings provide insights into the oropharyngeal microbial memberships and metabolic pathways that are involved in a piglet's weight gain. Thus, providing a basis for the development of strategies aimed at improving weight gain in pigs.

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.

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%.

Sixteen local sheep (8 male + 8 female) of about six months old with average live weight 10.78 $({\pm}1.11)$ kg were allocated into four treatments. The treatments (T) are : $T_0$ = Restricted grazing without concentrate; $T_1$, $T_2$ and $T_3$ = Grazing + 100, 200 and 300 g concentrate per sheep daily. Live weight of grazing (7.30 hrs daily) sheep was recorded in each week. The uncastrated male sheep were slaughtered for carcass and non-carcass parameters. Statistically significant (p < 0.05) differences were observed in live weight gain (g/day) among the treatments ($T_0=15.71$; $T_1=22.66$; $T_2 =32.66$ and $T_3=40.47$). The dressing % were : ($T_0=32.75$, $T_1=38.50$, $T_2=36.90 $ and $T_3=37.75$). The warm carcass weight represented 37.21% of live weight. Significant (p < 0.01) correlation were observed for live weight with carcass weight (r = 0.99) and dressing % (r = 0.88). Concentrate supplement increase live weight gain in sheep on grazing. Live weight is a good indicator to assess carcass characteristics.

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%.

Twenty crossbred calves of $88{\pm}5.5kg$ initial live weight and 3-4 month of age were divided into two groups and fed wheat straw and concentrate to support a 500 g daily gain in body weight. Calves in the experimental group (YC) were given a daily dose of 10 ml yeast cell suspension (YC) containing live cells $(5{\times}10^9 cells/ml)$ of Saccharomyces cerevisiae ITCCF 2094. After a growth study of 122 days metabolism trials were conducted. The calves in the YC group recorded a daily weigt gain of $492{\pm}27.8g$ as compared to $476{\pm}20.1g$ in control group. There were no significant differences in feed intake, nutrient digestibility, feed/gain ratio and nitrogen retention between the YC supplemented and control groups.

Data from 178 Jersey calves born at Livestock Experiment Station were analyzed to obtain estimates of heritability, genetic and phenotypic correlations of some growth traits. Sex-specific variance and covariance components were estimated for birth weight (BWT), 180-d weight (WWT), 365-d weight (YWT), birth to weaning daily gain (BWG), weaning to yearling daily gain (WYG) and brith to yearling gain (BYG). Heritabilities, genetic and phenotypic correlations were generally higher in males than females. Heritabilities estimated for males and females respectively were 0.98 and 0.49 for BWT; 0.70 and 0.76 for WWT; 0.71 and 0.26 for YWT. Genetic correlations were higher than phenotypic correlations in all the treats studied.
