The present study demonstrates a new approach that enables effective horse parentage testing using 22 ISAG microsatellite markers involving 6 heads of Thoroughbred horse(TB) and non-TB. In the comparison allele distribution between these horses, the alleles found in the TB were numerously detected in the non-TB. As results, we confirmed that these ISAG microsatellite markers might apply the pedigree registration of Korean native horse(Jeju horse).

Sixteen primary free amino acids were determined for each 10 longissimus muscles of Yorkshir, Landrace and Korean native black pig. Eight amino acids at 7 d classified three breeds at ca. 80% confidence. The difference in free amino acids for aged meats could be one of factors responsible for more desirable palatability of Korean native black pig.

The purpose of this study is the stability evaluation of soil slope according to inclination of upper natural slope. Upper natural slope breeds loss of slope by inflow in slope of surface water by rainfall and fluctuation of amount of materials in slope through method of cutting slope according to degree of inclination. Basis of standard inclination does not consider of inclination of upper natural slope and is presented uniformly. Therefore, in this study, analyzed stability of inclination of upper natural slope through limit equilibrium analysis.

The analyses of relationship between specific genes and economic traits were performed on the basis of the genetic characterization of Korean native chicken in this study. Three generation reference pedigree was established from the several lines of Korean native chicken and cornish breed for the linkage analysis and many economic traits were collected for QTL(quantitative trait loci) detection. The experimental design were planed to detect QTLs of meat quality and laying performance from those two distinctive breeds.

The aim of this study was to compare the plasma progesterone concentrations during gestation in 4 breeds of companion bitches. When Day 0 was timed the first male acceptance, plasma progesterone were 1.8 ± 0.4 ng/ml (Mean ± SD) at Day 0 and increased constantly with 58.5 ± 8.9 ng/ml a peak at Day 20. Thereafter plasma progesterone concentrations was decreased below 1.0 ng/ml with 0.7 ± 0.2 g/ml at Day 65. There were no statistically significant differences of plasma progesterone concentrations in the each day of gestation and in litter size among the companion bitches (p < 0.01). These results indicated that the plasma progesterone concentrations was useful method for estimating optimal breeding time, ovulation time, the time of onset of parturition, properly planned elective cesarean section and abortion time in companion bitches.

Background: Echocardiography is a primary tool used by veterinarians to evaluate heart diseases. In recent years, various studies have targeted standard echocardiographic values for different breeds. Reference data are currently lacking in Maltese dogs and it is important to fill this gap as this breed is predisposed to myxomatous mitral valve disease, which is a volume overload disease. Objectives: To establish the normal echocardiographic parameters for Maltese dogs. Methods: In total, 23 healthy Maltese dogs were involved in this study. Blood pressure measurements, thoracic radiography, and complete transthoracic echocardiography were performed. The effects of body weight, age and sex were evaluated, and the correlations between weight and linear and volumetric dimensions were calculated by regression analysis. Results: The mean vertebral heart size was 9.1 ± 0.4. Aside from the ejection fraction, fractional shortening, and the left atrial to aorta root ratio, all the other echocardiographic parameters were significantly correlated with weight. Conclusion: This study describes normal echocardiographic parameters that may be useful in the echocardiographic evaluation of Maltese dogs.

In recent years welfare of animals is the biggest challenge because animals, especially dogs are widely recognized as pet as well as they are using as service animals. So, for the wellbeing of the dog it is necessary to perform objective assessment to track their behavior in everyday life. In this paper, we have proposed an automatic behavior assessment system for dogs based on a neck worn and tail worn accelerometer and gyroscope platform, and data analysis techniques that recognize typical dog activities. We evaluate the system based on the analysis of 8 behavior traits in 3 dogs, incorporating 2 breeds of various sizes. Our proposed framework able to reproduce the manual assessment that is based on the video recording which is treated as gold standard that exhibits the real-life use case of automated dog behavior analysis.

In the present study, twelve bivoltine silkworm races were evaluated for its performance based on quantitative and qualitative traits. Seven oval and five peanut cocoon shaped races were reared in different seasons of the year. By using evaluation index method, the results showed that six races were identified as potential parental races. Among oval races, 75xin, KoC, KoZ and among peanut races An 902, 7532 and QD7 were selected as base material. The identified high yielding races will be used in various breeding programs as initial parents for the production of superior bivoltine breeds/hybrids in Vietnam

Machine-learning techniques are discovering effective performance on data analytics. Classification and regression are supported for prediction on different kinds of data. There are various breeds of classification techniques are using based on nature of data. Threshold determination is essential to making better model for unlabelled data. In this paper, threshold value applied as range, based on min-max normalization technique for creating labels and multiclass classification performed on rainfall data. Binary classification is applied on autism data and classification techniques applied on child abuse data. Performance of each technique analysed with the evaluation metrics.

This study was carried out to investigate the effects of semen characteristics, frozen-thawed sperm viability and serum FSH, LH, estradiol-17β and testosterone concentrations between breeds and among seasons in boars. In all seasons, Yorkshire boars produced higher semen volume compared with Duroc boars, whereas sperm concentration did not differ significantly between Duroc and Yorkshire boars. Semen volume in spring was higher compared with summer, autumn and winter in both Duroc and Yorkshire boars, but sperm concentration did not differ significantly among seasons. Sperm motility and normal acrosome rate of frozen-thawed sperm produced in spring were higher than those in summer, autumn and winter in both Duroc and Yorkshire boars. Sperm motility of frozen-thawed sperm in Yorkshire boars was higher than that in Duroc boars regardless of seasons. However, normal acrosome rate did not differ significantly between Duroc and Yorkshire boars. Serum FSH concentration in Yorkshire boars was lower than that in Duroc boars in all seasons. However, there were no significant differences on serum FSH concentration of Duroc and Yorkshire boars among seasons. Serum LH and estradiol-17β concentrations did not differ significantly between Duroc and Yorkshire boars. Also, there were no significant differences in serum LH and estradiol-17β concentrations of Duroc and Yorkshire boars among seasons. Serum testosterone concentration in Yorkshire boars was higher than that in Duroc boars in all seasons. In both breeds, serum testosterone concentrations were higher in spring than in summer, autumn and winter. In conclusion, when serum FSH concentrations were low, semen volumes were high, and when serum testosterone concentrations were high, sperm motility and normal acrosome rate of frozen-thawed sperm were high.
