본 연구는 젖소에서 분만 후 비유초기 체세포 증가가 번식효율에 미치는 영향에 대하여 조사하였다. 774두의 젖소 자료를 분만 후 3개월 평균 체세포지수에 따라 T1(3.0 미만, n = 521), T2(3.0 이상 4.0 미만, n = 113) 및 T3(4.0 이상, n = 140) 군으로 구분하였다. 자궁내막염의 발생위험율(odds ratio)은 T1군에 비해 T2군 및 T3군이 각각 1.6배(p < 0.05) 및 3.2배(p < 0.0001) 증가하였다. 분만 후 150일까지 첫 수정율은 T1군에 비해 T3군이 낮았으나(hazard ratio [HR] = 0.76, p < 0.01), 분만 후 첫수정 수태율은 각... -

The objective of this study was to compare ovulation rate, number of large ovarian follicles, and concentrations of plasma progesterone (P4) and non-esterified fatty acids (NEFA) between lame (n = 10) and non-lame (n = 10) lactating Holstein cows. The study was conducted in an organic dairy farm, and cows were evaluated by undertaking ultrasonography and blood sampling every 3 days from 30 days postpartum for a period of 34 days. Cows which became lame during the first 30 days postpartum... -

대한수의학회 Journal of Veterinary Science 2015, 제 16권 제 3호 2 253-263 (11 pages)
Cows infected with Escherichia (E.) coli usually experience severe clinical symptoms, including damage to mammary tissues, reduced milk yield, and altered milk composition. In order to investigate the host response to E. coli infection and discover novel markers for mastitis treatment, mammary tissue samples were collected from healthy cows and bovines with naturally occurring severe E. coli mastitis. Changes of mammary tissue proteins were examined using two-dimensional gel... -

Somatic cell nuclear transfer (SCNT) is a cost-effective technique for producing transgenic pigs. However, abnormalities in the cloned pigs might prevent use these animals for clinical applications or disease modeling. In the present study, we generated several cloned pigs. One of the pigs was found to have intrapancreatic ectopic splenic tissue during histopathology analysis although this animal was grossly normal and genetically identical to the other cloned pigs. Ectopic splenic tissue in the... -
A simplified one-step nuclear transfer procedure alters the gene expression patterns and developmental potential of cloned porcine embryos
Sang Kyu Park, Sangho Roh*, Jong-Im Park* 대한수의학회 Journal of Veterinary Science 8 Pages
대한수의학회 Journal of Veterinary Science 2014, 제 15권 제 1호 8 73-80 (8 pages)
Various somatic cell nuclear transfer (SCNT) techniques for mammalian species have been developed to adjust species-specific procedures to oocyte-associated differences among species. Species-specific SCNT protocols may result in different expression levels of developmentally important genes that may affect embryonic development and pregnancy. In the present study, porcine oocytes were treated with demecolcine that facilitated enucleation with protruding genetic material. Enucleation and donor... -

Recently, we reported the three wolves cloning with normal karyotype from somatic cells of endangered male gray wolves (Canis lupus), but one wolf had female external genitalia. In this study, we conducted further clinical, histological, and genetic analyses. This cloned wolf had a normal uterus but developed ovotestis. Through molecular analysis of the SRY gene, a mutation in the coding sequence of SRY gene could be excluded as a cause of intersexuality. This is the first report of a cloned... -

Factors affecting bacteriological cure rates (BCR) and new intramammary infections (IMI) during the dry period as well as clinical mastitis (CM) during early lactation were investigated in 414 German Holstein dairy cows receiving dry cow therapy. Cows were treated with either benethamine benzylpenicillin (300,000 IU), penethamate hydriodide (100,000 IU), and framycetin sulphate (100 mg, n = 136), or cefquinome (150 mg, n = 135), or benzathine cloxacillin (1,280 mg, n = 143). Overall BCR, IMI,... -

Salmonella (S.) Typhimurium and S. Enteritidis are the major causative agents of food-borne illnesses worldwide. Currently, a rapid detection system using multiplex real-time polymerase chain reaction (PCR) has been applied for other food-borne pathogens such as Escherichia coli, Staphylococcus aureus and Streptococcus spp. A multiplex real-time PCR was developed for the simultaneous detection of Salmonella spp., especially S. Typhimurium and S. Enteritidis, in beef and pork. For the specific... -

a milk quality somatic cell count (SCC) standard that could be used as an integral component of a control program. In all, 396 quarter milk samples from lactating cross-bred cows (Holstein & Zebu) were analyzed; 56% of these quarters were experiencing intramammary infection, with an overall mean SCC of 5.46 × 105 ± 2.30 × 104cells/ ml. Infected quarters had significantly (p < 0.05) higher mean SCC levels (6.19 × 105± 4.40 × 104cells/ml) compared to healthy quarters (2.65 × 105 ± 2.40 ×... -

clinical signs, microbiology and California mastitis test (CMT), while milk quality was evaluated using total viable count (TVC)and total coliform count (TCC). Animals were tested for tuberculosis using a single comparative intradermal tuberculin test. The prevalence of subclinical mastitis based on CMT was low (8.3%). The major isolates were Staphylococcus aureus (35.3%), other staphylococci (20.8%), coliforms (27.7%), microcci (5.8%) and streptococci (9.8%). The average TVC of milk in Dodoma... -

Five monoclonal antibodies (MAbs) and chicken immunoglobulin (IgY) were developed by immunizing with flagella purified from Listeria monocytogenes 4b and the five MAbs have been confirmed to be specific against three different epitopes of flagellin. The antibodies showed specific reaction to Listeria genus and no cross-reactivity with other bacteria tested in this experiment including E.coli O157:H7 and Salmonella enteritidis. Sandwich enzyme-linked immunosorbent assays (ELISA) using the MAbs... -

Bovine mastitis is an infectious disease with a major economic influence on the dairy industry worldwide. Many factors such as environment, pathogen, and host affect susceptibility or resistance of an individual cow to bovine mastitis. Recently, there has been considerable interest in defining genetic and immunological markers that could be used to select for improved disease resistance. In this study we have analyzed the lymphocyte subpopulations of mastitis-resistant and susceptible cows using... -

(n = 239) were aseptically collected from lactating cows in the Rift Valley of Kenya and tested using the CMT, somatic cell counts (SCC) and bacterial culture. The samples were also screened for violative drug residues using the commercial delvo test and compared to the milks mastitic status for possible association. There was a numerical but non-significant (p > 0.05) difference evident in the frequencies observed using the three different mastitis indicators. The prevalent bacterial species... -

In the present study 130 S. uberis strains and one S. parauberis strain isolated from bovine milk samples of 58 different farms of various locations in Hesse, Germany, as well as two reference strains of each species were comparatively investigated for cultural, biochemical, serological and molecular properties. All S. uberis strains produced the enzyme β-D-glucuronidase, while the S. parauberis strains were negative. The S. uberis and S. parauberis 16S rRNA genes were amplified by polymerase... -

This experiment was conducted to assess the efficacy of typhoid vaccine newly produced by purifying Vi antigen of Salmonella typhi. With Karber method, LD50 of challenging organism (S. typhi ty2) was determined as 6.31 CFU/mouse, and then the organism was used for the study. With Probits method, ED50 of the vaccine was determined as 0.016 microg / 0.5 ml / mouse. The ELISA titer (0.50970.0606) was 4 times in the group treated with high dose (0.25 microg/0.5ml) as in control (0.11130.0110). Six... -
