For the evaluation of breeding values of animals, A trial to get solutions from the Iterative(SUR: Successive underrelaxation method) and the G-inverse was carried out using a sire model with 76 levels of 7 independent factors in this study. The results showed no differences between the solutions from directive(G-inverse) method and that from iterative method. For the four(0.1, 0.2, 0.3, 0.35) different relaxation factors(W) to speed up the convergence to the final solution, even though the number of rounds of interaction was affected, there were no differences in the final solutions. The numbers of rounds of iteration t get final solutions from a restriction({ b₁^n+1 - b₁} $lt;0.0001) under for the 0.1, 0.2, 0.3 and 035 relaxation factors were 1729. 928, 649 and 563 rounds respectively. It is the good iteration parameter(w) whether the convergence is speeded up or not. Since Iterative method is very simple to be programized and needs relatively small computer memory, it could be useful for solving large and complex equations in animal evaluation.

This study was carried out to estimate the heritabilities of body weight, shank length and shank width and to investigate the genetic correlation between the body weight at 20 wks and the other body measurements in growing period for pheasant(phasianus colchicus). The heritability estimates were in the range of 0.44∼0.73 for body weight, 0.27∼0.79 for shank length and 0.45∼0.71 for shank width in the growing period. The heritability estimates of body weight, shank length and shank width for male were slightly heigher than those for female at 4 wks old while the estimates at 12 wks and 20 wks were heigher for female than those for male. The heritability of daily body weight gains during 1-d to 4 wks, 5 to 12 wks, and 13 to 20 wks of age were 0.51, 0.46 and 0.30 for male and 0.39, 0.59 and 0.36 for female, respectively. The phenotypic and genetic correlation coefficients between the 20 wks body weight and other body measurements in the growing period were 0.24∼0.70 and 0.36∼0.85, respectively. Phenotypic and genetic correlation coefficients of 20 wks body weight with daily body weight gain during 5 to 12 wks were heigher than any other estimates with the daily weight gains.

In the analysis of genetic characteristics based on results of DNA fingerprints of Korean native cattle (Hanwoo) and other cattles(Holstein, Charolais, Aberdeen Angus, and Simmental), the Korean native cattle was found to be the lowest in homozygosity and genetic similarity within breed, allelic frequency, band frequency, and band sharing. It can be suggested that Korean native cattle have more capacity of genetic improvement than others, in the other hand strategies for genetic improvement of Korean native cattle used until now need to be reappraised.

Purpose: To compare the outcomes of autogenous dermis fat grafting with different donor sites in the treatment of exposed porous orbital implants. Methods: The present study retrospectively evaluated the medical records of 17 patients (17 anophthalmic eyes) who had undergone autogenous dermis fat grafting based on the diagnosis of exposed porous orbital implants and were regularly followed up for at least 12 months since the surgery from January 2001 to December 2010. The patients were divided into 2 groups (thigh and abdomen) according to the site of the donor grafting. The treatment outcome and complications were compared between the 2 groups. Results: The success rate of thigh dermis fat grafting was 88.9% (8/9) and 100.0% (8/8) in the abdominal dermis fat grafting, and there was no statistically significant difference between the 2 groups (p = 1.000). Regarding ocular complications, graft tissue infection (thigh 11.1%, abdomen 0%) and superior sulcus deformity (thigh 22.2%, abdomen 25.0%) were present. Regarding donor site complications, tenderness (thigh 55.6%, abdomen 25.0%), dehiscence (thigh 22.2%, abdomen 25.0%) and scar formation (thigh 33.3%, abdomen 25.0%) were observed. In the gait associated complications, pain (thigh 55.6%, abdomen 25.0%) and limping (thigh 22.2%, abdomen 12.5%) were observed. The rate of all complications showed no statistically significant difference between the thigh dermis fat grafting and the abdominal dermis fat grafting (all p > 0.05). Conclusions: Thigh and abdomen can both be considered as an effective donor site for the autogenous dermis fat grafting in the treatment of exposed porous orbital implants.

The purpose of this paper is to investigate the performances of the body weights and the 11 body measurements of Hanwoo raised between 1987 and 1989 in farms and Hanwoo progeny test center. The body weights at birth, 6, 12, 18 and 24 months of age were 22.49kg, 148.18kg, 223.48kg, 267.76kg, and 291.77kg respectively. The body measurements were increased rapidly up to about 6 months of along with the body weight. Feeding managements and the nursing capacity of dam were considered important. factors to develop the body size of a calf early growing stage. As compared with the previous reports, for the body weights at 6 and 12 months of age and the measurements for body length, chest girth, and shank circumference at 6, 12 and 18 months of age were somewhat increased. This might be come from the improved feeding managements and the change of growth type by selection. The hipbones width(pinbones width), which had not been reported, at birth, 6, 12, 18 and 24 months of age were 8.96cm, 19.09cm, 19.26cm, 21.04cm, and 22.19cm respectively. The body measurements of 11 traits of male calves at 7 months of age shown to be similar to those of female calves at 12 months of age.

To investigate genetic features and the allele distribution of transferrin gene in three Cheju horse groups(group Ⅰ, 137 horses of Jeju institute; group Ⅱ, 107 horses of farms; group Ⅲ, 89 racing horses) and three foreign breeds(103 Thoroughbred, 10 Mongolian and 5 American Quarter horses), transferrin gene exons 13, 15, and 16 were analyzed by SSCP. The allele frequencies of transferrin gene of these groups and breeds were used to calculate genetic distances and to test population differentiations. The Fst values were 0.067 between Cheju horse groups Ⅰ and Ⅱ, 0.070 between Cheju horse groups Ⅰ and group Ⅲ, 0.091 between Cheju horse group Ⅰ and Mongolian breed, and 0.189 between Cheju horse group Ⅰ and Thoroughbred breed, Cheju horse group Ⅰ showed significant population differentiation from other two Cheju horse groups and three foreign breeds while Cheju horse group Ⅲ showed significant population differentiation only from Cheju horse group Ⅰ and Thoroughbred breed)p,0.05). Results indicate that three Cheju horse groups showed population differentiation between each other, suggesting genetic heterogeneity of Cheju horses.

To determine the effect of the hatching egg weight on the newly hatched chick weight and the body weight at 20 wks, body weights were analysed with a linear model which had the fixed effects of the hate-time and the sex, and a covariable of hatching egg weight. The correlation coefficient between hatching egg weight and 1-d old chick weight was 0.83(p$lt;0.01), and between hatching egg weight and the body weight at the age of 20 wks was 0.17(p$lt;0.01). Hatch-time effects on the body weight at 1-d and the body weight at 20 wks were significant(p$lt;0.01) but the sex effect on the day old chick weight was not significant(p$gt;0.05). Estimates of the regression coefficients of the body weight at 1-d and the body weight at 20 wks were 0.69±0.02 (p$lt;0.01) and 11.24±1.70 (p$lt;0.01), respectively. These results showed that the hatching egg weight affected the body weight of newly hatched chick and the body weight at 20 wks.
