A comparative study was performed to investigate the efficacy of KiFAY as a feed additive on performance parameters, thyroid, and pancreatic hormone levels in broilers. Ninety birds (Vencobb 400) were randomly divided into three groups viz., Control (no DL-methionine supplementation), Treatment1 (containing added DL-methionine) and Treatment 2 (containing KiFAY and without DL-methionine supplementation). The performance parameters (weekly body weight, body weight gain, feed intake, and feed consumption ratio) were recorded and calculated during the whole study of 4 weeks. Analyses of insulin and insulin-like growth factor (IGF 1), triiodothyronine (T3), thyroxine (T4) and thyroid stimulating hormone (TSH) were performed at the end of the study. The results show that birds on supplementation of KiFAY performed significantly (p<0.001) better than other treatments. The weekly body weight, body weight gain, feed in-take and feed consumption ratio improved in KiFAY treated birds. The study found an increase in insulin and IGF1 levels (p<0.001) in KiFAY compared with the other treatments. Serum T3, T4, and TSH levels in the Treatment 2 were higher than other treatments (p<0.001). The KiFAY supplementation was able to improve performance with associated responses at a hormonal level in broilers.

The effect of nose radius on aerodynamic heating is investigated by using the Navier-Stokes code extended to thermochemical nonequilibrium airflow, Spherical blunt bodies, whose nose radius varies from 0.O03048 m to 0.6096 m, flying at Mach 25 at an altitude of 53.34 km are considered. Comparison of heat flux at stagnation point with the solution of Viscous Shock Layer and Fay-Riddell are made. Results show that the flow for very small radius is in a nearly frozen state, and therefore the heat flux due to diffusion is smaller than that due to translational energy. As the radius becomes larger, the portion of heat flux by diffusion becomes greater than that of heat flux by translational temperature and approaches to a constant value.

The effect of nose radius on aerodynamic heating are investigated by using the Wavier-Stokes code extended to thermochemical nonequilibrium airflow. A spherical blunt body, whose radius varies from 0.003048 m to 0.6096 m, flying at Mach 25 at an altitude of 53.34 km is considered. Comparison of heat flux at stagnation point with the solution of Viscous Shock Layer and Fay-Riddell are made. Obtained result reveals that the flow chemistry for very small radius is nearly frozen, and therefore the contribution of heat flux due to chemical diffusion is smaller than that of translational energy. As the radius becomes larger, the portion of diffusion heat flux becomes greater than translational heat flux and approaches to a constant value.

The purpose of this study is to investigate the differences in body fat distribution between obese boys and girls in high school and the relationship between the precent of body fat and the Broca Index. The survey of data was conducted from November 3rd to the 11th in 1997. The data were analyzed by the use of a mean, standard deviation and a Pearson's correlation coefficient. Measurements of the percentage of body fat and lean body mass were made by a Bioelectrical Impedence while height, weigh and the Broca index were measured by a fatness measuring system. First, measurements of height, weight and the Broca index were made by a fatness measuring system on 1,125 1st year students and 1,076 2nd year students. The result of measurements, 216 obese boys and 100 obese girls appeared to have above 10% of the Broca index. The result of this study can be summarized as follows: 1) Obese boys and girls were grouped by the level of the Broca index as follows: boys, 110-less than 120 60.0%, 120-less than 130 20.8%, 130-less than 140 11.1%, above 140 7.4%. ; girls, 110-less than 120 44.4%, 120-less than 130 32.0%, 130-less than 140 13.0%, above 140 11.0%. 2) Obese boys and girls were grouped by level of the percentage of body fat by Bioelectrical Impedence as follows: boys, less than 20% 5%, 20%-less than 25% 34.7%, above 25% 33.8% ; girls. less than 25% 15.0%, 25%-less than 30% 43.0%, above 30% 42.0%. 3) In obese boys the Broca index score appeared to be positively related to body weight(r = .741, p<.001), the percent of body fat(r=.604, p<.001), lean body mass(r=.375, p<.001), body fluid(r=.445, p<.001l). On the other hand the percent of body fat was not a significant correlation of lean body mass (r= -.074), body fluid(r= -.073). 4) In obese girls, the Broca index score appeared to be positively related to body weight(r= .693, p<.001), the percent of body fat(r=.645, p<.001), lean body mass(r=.531, p<.001), body fluid(r=.532, p<.01), and the percent of body weight score appeared to be positively related to lean body mass(r=.206, p<.01), body fluid(r=.207, p<.01).

Objective: The aim of the present study was to determine the effect of supplementing pasture-finished steers with corn silage on the expression level of the calpain system proteins and beef tenderization. Methods: Thirty Braford steers grazing on summer pasture were used for the study. For 120 days fifteen animals were supplemented with corn silage at 1% of body weight per head per day (Suppl) whereas the remaining 15 steers only received pasture (Contr). Carcass and meat traits were evaluated and compared between groups. Gene expression and activities of proteases (calpain 1 and calpain 2) and inhibitor (calpastatin) were measured using real-time polymerase chain reaction and casein zymography. Results: Carcass and meat traits were significantly different between feeding systems. Supplemented steers showed higher hot carcass weight (p<0.01), fat content (p = 0.02), and Warner-Bratzler shear force (p = 0.03). Furthermore, the control group showed higher protease:inhibitor ratios, at mRNA (p = 0.01) and protein levels (p<0.10). Warner-Bratzler shear force and mRNA calpains:calpastatin ratio were associated in both feeding systems (p<0.01). Conclusion: Based on the results obtained in the study, beef tenderness differences among finishing strategies could be modulated through differential expression of the calpain system proteins.
