  • For the purpose of investigating the factor of foot and calf growth of primary-school children who are fast-growing during this period a group of the 1st graders of primary-school had been the subject of this measurement in 1995 and there after they became the subject again in 1997, 1999 when they were the 3th, 5th graders measurement was carried out in 30 items including status and weight and marthin-type measure and foot-print were used for this measurement as the result, stature is correlated with height items and length items of foot and calf weight is correlated with width and circumference items of foot and calf angle of the first toe showed the highest growth like 3rd graders, heel circumference had rapidly grown rather than in the part of foot circumference in the factor analysis df foot measurement of 10-year, the first, second factors, appeared the size of shoes, in case of 12-year the first factor with status appeared the size of shoes.

  • To evaluate direct and maternal effects on calf market weight (CMW) and carcass weight (CW) in Japanese Black cattle under an animal model, genetic parameters were estimated using 51,320 records of CMW and 11,944 records of CW, respectively. Direct and maternal heritabilities, and direct-maternal genetic correlation were estimated to be 0.22, 0.06 and 0.27 for CMW, and 0.23, 0.12 and -0.40 for CW, respectively. Correlation coefficient between maternal breeding values for CMW and CW was 0.521 for 157 sires appeared in both CMW and CW data sets. These results suggest that the maternal genetic effect on pre-weaning growth carries over to carcass weight. Maternal breeding values for both calf market weight and carcass weight could be used as the indicator traits of maternal ability in Japanese Black cattle.

  • Spermine has opposite effect on the susceptibility of native and denatured calf thymus DNA toward deoxyribonuclease Ⅰ (DNase I; deoxyribonucleate 5'-oligonucleotidohydrolase; EC 3.1.4.5; from bovine pancreas). It enhances the susceptibility of the native DNA, whereas depresses that of the denatured DNA. In the absence of spermine, the reactivity of the deoxyribonuclease is apparently insensitive to the conformational difference of the native and denatured DNA.

  • To know and apply the factors affecting calf's gender may increase our competitiveness of Hanwoo industry. Thus, this study was carried out to analyse the effect of expected factors on calf's gender and to make an alternative idea for desired calf's gender. Gender of calves born by AI was not affected by AI year and cow parity, but significantly affected by sire and farm. Therefore, to obtain calves' gender that we want, both selecting optimum sire for AI and providing optimum feeding environment for cow should be required.

  • A female Holstein calf with five legs and two tails was examined macroscopically and radiographically. The external feature included two normal forelimbs, two normal hindlimbs, a normal tail and each of underdeveloped extra hindlimb and tail, which was attached to the pelvic region. The extra hindlimb consisted of an underdeveloped femur, crural meromelia, duplicated calcaneous, partially duplicated metatarsal bone, three rows of digits with hoofs. This extra hindlimb was connected to an extra os coxa. The cervical and thoracic vertebrae were fused partially. The lumbar, sacral and coccygeal vertebrae were duplicated. This calf is a dipygus associated with pygopagus parasiticus.

  • Purpose: The purpose of this study was to investigate the immediate effects of calf muscle Kinesio taping on ankle joint reposition sense (JRS) and force sense (FS) in healthy elderly. Methods: Thirteen healthy elderly subjects were participated in this study. The error of ankle JRS and FS was evaluated by 3D motion capture device and digital dynamometer depending on three different taping conditions (Kinesio taping, sham taping, and no taping) respectively. All of subjects were asked to perform a proprioceptive task of ankle JRS and FS. One-way repeated ANOVA test was used to compare the error of JRS and FS depending on three different taping conditions. Results: With Kinesio taping over calf muscle, ankle joint reposition sense error and force sense error significantly decreased, if compared with a sham taping or no taping condition. Conclusion: To apply Kinesio taping over calf muscle could enhance ankle proprioceptive sense in the elderly people.

  • This paper describes the development of neurological signs of two prematurely born calves four days after birth. The pathological examination results indicated fibrinopurulent polyserositis, including meningoencephalitis with suppurative bronchopneumonia. Bovine viral diarrhea virus subtype 2a was detected in most of the internal organs, and the bacterial colonies cultured from the samples were identified as Klebsiella (K.) pneumoniae. Molecular analysis via multilocus sequence typing identified a different K. pneumoniae isolate in each calf-type 14 in calf A and type 65 in calf B. This is the first report identifying K. pneumoniae sequence types 14 and 65 in cattle.

  • Cyclopia is a congenital ocular abnormality in which two orbits are fused together due to an arrest in the normal process of embryonic tissue development. Reported here is a case of cyclopia in a calf observed from the uterus of cow slaughtered in an abattoir in Korea on March 24, 2004. The calf possessed a spherical-shaped head and only one centrally placed eye. The one eyeball showed complete eyelashes on the defective eyelids. The nasal region and the anterior nares were absent along with a dorsally curved mandible extended beyond the defective maxillae.

  • To correlate the conformational changes of DNA (Calf Thymus) with entrapment of DNA into liposomes, the effect of ions ($Na^+$, $Mg^{++}$on the entrapment of calf thymus DNA into liposomes was investigated. The effect of divalent ion ($Mg^{++}$ on the structural changes of DNA indicated by decrease of observed ellipticity at 274 nm and nonspecific binding of DNA to lipid bilayers was greater than monovalent ion ($\Na^+$). But the efficiency of DNA encapsulated was not altered. These results show that entrapment of DNA into liposomes is not due to nonspecific binding and structural changes because of electrostatic forces but to mechanical capture of DNA by the internal aqueous space of liposomes although divalent ion contributes large structural changes and more nonspecific association of DNA with liposomes due to strong charges.

  • A 2-month-old, 50 kg male Korean native calf was referred with bilateral mandibular fractures. The bilateral mandible was hanging loose, with inability to use the jaw, indicated by excessive salivation. Radiography revealed a long oblique fracture in the right mandible, and a short oblique fracture in the left mandible. Computerized Tomography, a different form of radiography, revealed the fracture in the left mandible to be a comminuted fracture. In order to stabilize the bilateral mandible fractures, a combination of bone plate and wiring was applied; in addition, resin was applied to enhance stabilization of the mandible. Six weeks after surgery, the calf was able to masticate and ruminate well. In this case, application of the plate and wiring with resin to bilateral mandibular fractures presented a successful functional recovery. Accordingly, the combination of bone plate and wiring with resin can be an effective technique for treating mandibular fractures.
