Genetic variation at 25 microsatellite loci, population structure, and genetic bottleneck hypothesis were examined for Ankleshwar poultry population found in Gujrat, India. The estimates of genetic variability such as effective number of alleles and gene diversities revealed substantial genetic variation frequently displayed by microsatellite markers. The average polymorphism across the studied loci and the expected gene diversity in the population were 6.44 and 0.670${\pm}$0.144, respectively. The population was observed to be significantly differentiated into different groups, and showed fairly high level of inbreeding (f = 0.240${\pm}$0.052) and global heterozygote deficit. The bottleneck analysis indicated the absence of genetic bottleneck in the past. The study revealed that the Ankleshwar poultry breed needs appropriate genetic management for its conservation and improvement. The information generated in this study may further be utilized for studying differentiation and relationships among different Indian poultry breeds.

Somatic cell counts (SCCs) of goat milk can vary widely depending on the counting methods used and non-pathogenic factors; the goat milk industry can be threatened by establishment of a legal standard based on the findings in cow milk. In Korea, SCCs have been excluded from the items that are analyzed under the "Livestock Products Processing and Composition Standards" in accordance with a recent NVRQS Notice amendment. From April to October, SCCs of 150 goat milk samples from 2 farms were analyzed using a Somascope calibrated with standard goat milk samples. Average SCCs of the samples was 598,000/mL, and significant differences were not found between farms and between breeds. SCCs increased from 3 to 8 months after delivery.

The implications of temperature (25,30 and 35$^{\circ}C$) and relative humidity (60, 70 and 80%) on the pupation patterns were studied in the silkworm, Bombyx mori L. Larvae of two pure silkworm breeds, Pure Mysore (PM) and NB4D2 and their hybrid, PM ${\times}4 NB4D2 were reared under experimental conditions under natural day photoperiodic (LD 12: 12) condition. The three developmental marker events viz., larval ripening, pharate pupal formation and pupal formation occurred at or around the beginning of the photo-phase. The computed of mean vector (equation omitted), based on the circular statistics, also confirmed the above. However, the length of mean vector, r and the mean vector angular variance, s varied according to temperature and humidity conditions imposed; the variations being non-significant. Extreme temperature and humidity conditions, however, resulted in reduction in pupation rate (%) for PM and PM ${\times}4 NB4D2. On the other hand, in NB4D2 pupation percentage reduced below the economic level. The temperature and humidity together seems to exert synergic impact on the pupation rate at least in the silkworm Bombyx mori, L.

Parthenogenetic development, hybrid vigour and cocoon shape variability were studied in bivoltine F1 hybrids of the silkworm, Bombyx mori L. Considerable breed differences were observed in parthenogenetic ability. Among the parental breeds, CSR18 exhibited maximum parthenogenetic development (79.65%) followed by CSR4 (67.90%). Among bivoltine F1 hybrids, CSR18 ${\times}$ CSR4 showed highest parthenogenetic development (73.32%) followed by CSR2 ${\times}$ CSR4 (55.43%). Study on hybrid vigour demonstrated that CSR18 ${\times}$ CSR19 expressed maximum significant hybrid vigour for all the seven economic characters over Mid Parent Value (MPV) followed by CSR2 ${\times}$ CSR4 and CSR18 ${\times}$ CSR4 exhibiting significant heterosis for six characters. Cocoon shape measurement study revealed that among ten bivoltine F1 hybrids, cocoons of three hybrids were found comparatively uniform. Importance of this study to know the level of paythenogenetic development, hybrid vigour and cocoon shape variability in different bivoltine F1 hybrids have been discussed.

The miniature pig is considered to be a better organ donor breed for xenotransplantation than other pig breeds because the size of the organs of the miniature pig is similar to that of humans. In this study, we aimed at identifying differentially expressed genes in the miniature pig ovary during pregnancy. For this, we used the miniature pig ovary model, annealing control primer-based reverse transcription polymerase chain reaction (PCR), quantitative real-time PCR (qRT-PCR), and northern blotting analysis. We identified 13 genes showing differential expression on the based of pregnancy status and validated 8 genes using qRT-PCR. We also sequenced the full-length cDNA of ephrin receptor A4 (EphA4), which had a significant difference in expression level, and validated it by northern blotting. These genes may provide a better understanding of the cellular and molecular mechanisms during pregnancy in miniature pig ovary.

Purpose: This study was to investigate the stress of parents while they were rearing their children. Method: This study reviewed the preceding research related to parents' stress and breeding stress with consideration of modem society, family system and parents' role. Results: In the parent-child relationship, parents feel stressed when they found it difficult to come up with an expectation to the parents' role of rearing child. Therefore, considering the health of parents and children, it is important to mediate parents who are under stress. Moreover, since parents cannot handle this problem all alone, it should be discussed and solved not only by individual but also by family, and further by social context. The parent-child relationship in early infancy is a core element to the development of an individual. Parents have influence on a child's development the most and play a big role. In particular, many parents these days believe that parent-child relationship is changing in a democratic way and a couple breeds their child together. However, in reality, the relationship has not been changed and is even regarded as more difficult situation than it was in the traditional society. Parents are oppressed with not being adapted to social changes and advance, and child also feels the same. Conclusion: Parents need education and support for child rearing without having any stresses. Health care provider consider this issues and to build a healthy parent-child relationship by helping parents.

This review addresses the characteristics and health benefit of highly marbled Wagyu and Hanwoo beef. Marbling of Wagyu and Hanwoo beef has been increased in Japan and Korea to meet domestic consumer preferences. Wagyu and Hanwoo cattle have high potential of accumulating intramuscular fat (IMF) and producing highly marbled beef. The IMF content varies depending on the feeding of time, finishing diet, and breed type. IMF increases when feeding time is increased. The rate of IMF increase in grain-fed cattle is faster than that in pasture-fed cattle. Fatty acid composition are also different depending on breeds. Highly marbled Wagyu and Hanwoo beef have higher proportions of monounsaturated fatty acid (MUFA) due to higher concentrations of oleic acid. MUFAs have little effect on total cholesterol. They are heart-healthy dietary fat because they can lower low-density lipoprotein (LDL)-cholesterol while increasing high-density lipoprotein (HDL)-cholesterol. Clinical trials have indicated that highly marbled beef does not increase LDL-cholesterol. This review also emphasizes that high oleic acid beef such as Wagyu and Hanwoo beef might be able to reduce risk factors for cardiovascular disease.

We report a novel HPLC method for analyzing the capsaicinoids and nonivamide. The following conditions were used: a total column and column temperature of $3^{\circ}C$, a detection wavelength of 280 nm, an eluent containing acetonitrile : 0.5% formic acid(31:69, v/v). The experimental data was compared with standard nonivamide and capsaicin. The results showed that nonivamide was eluted in 96.7 minutes with a recovery ratio of 96.5% after adding known nonivamide. In addition, the detection limit for nonivamide was 18.6 ng. The capsaicinoids from Korean pepper were extracted (after blooming 60th) from 3 breeds cultivated in Korea, Buchon, Chungyang and Hanbando. and crisis it analyzed sympathizes the nonivamide in the result nonivamide from the Buchon and the Chungyang which are not detected from the Hanbando $0.16{\sim}0.24{\mu}g/g$ it detects with very small amount it contains it confirmed the each capsaicinoid with the HPLC and the LC-MS. These results are expected contribute to the quality control of various product processes, which includes product delivery inspection as well as examining the capsaicinoids present in the product for possible medicine manufacture and various foodstuff, and the nonivamide content, which may be a feed for various manufacturing processes involving chemical synthesis.

To prevent the denaturation of ficin(EC 3.4.22.3) that is a proteolytic enzyme in fig(Ficus carica L.), fig conserve was heated to 55oC. The fig conserve was added as a tenderizer to native Korean cattle beef(KCB), dairy cattle beef(DCB), castrated dairy cattle beef(CDCB), and imported beef(IB). The composition of free amino acids, hydroxyproline content, shear force, cooking loss, morphological changes and sensory evaluation were then investigated to observe the effect of tenderizing beef with fig conserve. Free amino acids and cooking loss of treated beef were higher than those of control, whereas hydroxyproline and shear force were lower. Glutamine in treated beef decreased relatively but asparagine increased. Hydroxyproline was found, in increasing order of abundance, in DCB, CDCB, IB and KCB. By portion, loin was higher than tenderloin in free amino acids, hydroxyproline and shear force but was lower in cooking loss. Observation with a light microgram revealed a surprising loss of muscle fiber in treated beef. In sensory evaluation of uncooked beef, the control was redder than the treated beef(p<0.01~p<0.05). Treatment with fig conserve increased the juiciness of both cooked CDCB and IB(p<0.001) and decreased their hardness(p<0.01~p<0.001).
