To test the role of sows in spreading transmissible gastroenteritis (TGE), 11 sows were intravenously, intranasally, or intramammarily inoculated with virulent virus within 5 days of farrowing. Six of the sows were separated from their offspring, and 5 were allowed to nurse their litters. All sows became clinically ill with sign of anorexia, depression, and fever that persisted until postinoculation day 4 or 5. They shed virus through milk, nasal secretions, and feces, with individual variations occurring in degree and duration of shedding in the 1st week after inoculation. Of 40 pigs separately fed milk samples from the 6 inoculated sows, 19 pigs (47.5%) became sick in 24 to 40 hours, and virus was isolated from them at necropsy. Of 43 pigs in the 5 litters that nursed exposed dams, all became sick with typical signs of TGE, and 29 (67.4%) died in 2 to 9 days. Sows given the single intramammary inoculation of virus developed statistically significant higher levels of TGE virus-neutralizing antibodies than did sows inoculated intravenously or intranasally. 相似文献

Shedding of porcine reproductive and respiratory syndrome virus in mammary gland secretions of sows.
E A Wagstrom C C Chang K J Yoon J J Zimmerman 《American journal of veterinary research》2001,62(12):1876-1880
OBJECTIVE: To document shedding of porcine reproductive and respiratory syndrome (PRRS) virus in mammary gland secretions of experimentally inoculated sows, to evaluate effects of vaccination during gestation on virus shedding during the subsequent lactation, and to evaluate shedding of PRRS virus in milk of sows in commercial herds. ANIMALS: 6 sows seronegative for PRRS virus were used for experiment 1, and 2 sows were retained for experiment 2. For experiment 3, 202 sows in commercial herds were used. PROCEDURE: In experiment 1, 2 sows were inoculated with PRRS virus, 2 sows were vaccinated with modified-live PRRS virus vaccine, and 2 sows served as control pigs. Mammary gland secretions were assayed for PRRS virus. In experiment 2, pregnant vaccinated sows from experiment 1 were vaccinated with another modified-live PRRS virus vaccine. Mammary gland secretions were assayed in the same manner as for experiment 1. For experiment 3, milk collected from 202 sows in commercial herds was assayed for PRRS virus. RESULTS: In experiment 1, PRRS virus was detected in mammary gland secretions of both vaccinated and 1 of 2 virus-inoculated sows. In experiment 2, virus was not detected in samples from either vaccinated sow. In experiment 3, all samples yielded negative results. CONCLUSIONS AND CLINICAL RELEVANCE: Na?ve sows inoculated late in gestation shed PRRS virus in mammary secretions. Previous vaccination appeared to prevent shedding during the subsequent lactation. Results for samples obtained from sows in commercial herds suggested that virus shedding in mammary gland secretions of such sows is uncommon. 相似文献

The influence of weaning to oestrus interval, its interaction with parity and equine chorionic gonadotropin (eCG) on changes of vaginal impedance in sows after weaning was examined. The impedance measurements were carried out by a four‐terminal method. Sows were monitored for oestrus via exposure to a sexually mature boar. The interval from weaning to oestrus was longer in primiparous than multiparous sows (p < 0.01). A significant negative correlation was found between the interval from weaning to oestrus and parity. Repeated measures analysis showed that the interval from weaning to oestrus and parity and their interactions had a significant effect on the vaginal impedance in peri‐oestrus. The vaginal impedance during pro‐oestrus gradually decreased in all groups of sows with the weaning to oestrus interval from 4 to 8 days (p < 0.05). In the subsequent period, the vaginal impedance increased and was significantly lower from 1 to 3 days after oestrus onset in sows with the weaning to oestrus interval 7–8 days than 4–6 days. Similarly, the vaginal impedance during pro‐oestrus gradually decreased in all groups of sows with parity 1–5 (p < 0.01). In the next period, the vaginal impedance increased and was significantly lower from 2–3 days after oestrus onset in sows of parity 1 than parity 2–5. Repeated measures analysis showed that eCG treatment had a significant effect on the vaginal impedance in peri‐oestrus. Sows treated with eCG displayed the decrease and increase of vaginal impedance due to oestrus onset earlier than untreated sows. The results indicate that the weaning to oestrus interval, its interaction with parity and eCG markedly affect the vaginal impedance in sows during peri‐oestrus. 相似文献

产道作为母猪生殖系统的重要器官组织,与繁殖性能密切相关。本试验无菌采集江西省某养殖场窝产14头母猪产道中段阴道分泌物进行传统细菌分离培养,初步筛选出4株细菌,挑选其中一株通过生化反应和16S rDNA序列分析方法进行鉴定,同时进行抗生素抵抗能力试验和牛津杯法体外抑制试验。生化鉴定结果表明该菌可降解果糖、乳糖、半乳糖等,该菌代谢产物与葡萄糖酸盐无反应,葡萄糖产气试验说明该菌产酸不产气。分离菌株通过NCBI同源性比对为粪肠球菌（登录号EU794735.1）。分离菌对青霉素、头孢哌酮等高度敏感,对红霉素、庆大霉素等耐药。体外抑制试验中分离菌对大肠杆菌k88和变形杆菌具有良好的抑制效果,可以作为候选益生菌株进行深入研究。这为今后益生菌代替抗生素及产道菌群移植防治母猪产道炎症提供理论基础。 相似文献

The aim of present study was to study the effect of post-ovulatory insemination on the subsequent embryonic loss, oestrous cycle length and vaginal discharge in sows. Ten Large White multiparous sows were divided into two groups. Group A sows were inseminated once at 15 h after ovulation. Thereafter, they were ovariohysterectomized on day 11 (n = 5, first day of standing oestrus = day 1) and flushed for recovery of embryos. Group B sows were also inseminated once at 15 h after ovulation. They were further observed for return to oestrus and vaginal discharge (n = 5) after insemination. The endometrium tissues were biopsied from sows with vaginal discharge, embedded with paraffin, stained with haematoxylin and eosin and examined under light microscope. Only two embryos were observed in one of four sows from group A. All embryos had a spherical shape but differed in size (range 1-2 mm). In group B, only one sow had a regular return to oestrus (i.e. on day 23) and another sow had an irregular return to oestrus (i.e. on day 27). The other two sows in this group had shown vaginal discharge on days 20 and 38 after standing oestrus. For the number of leucocytes in the endometrium of sows with vaginal discharge, a large number of lymphocytes and plasma cells were observed in the connective tissue of the subepithelial layer. In conclusion, post-ovulatory insemination resulted in early embryonic loss, a subsequent prolonged oestrus interval and also vaginal discharge (i.e. endometritis) in sows. 相似文献

Two pregnancy diagnosis techniques, vaginal biopsy and ultrasonic detection, were applied to 190 sows following service. Of 172 sows diagnosed pregnant by vaginal biopsy, five did not farrow. Of 18 sows judged not pregnant, one produced a litter. With the ultrasound technique, 175 sows were diagnosed pregnant, but 11 did not farrow. Of the remaining 15 sows considered not pregnant by the 39th day after service, four farrowed. The biopsy result was usually available up to 48 hours earlier than the ultrasound result. It was concluded that where laboratory facilities are available, the biopsy technique is the method of choice. 相似文献

Anti-adhesive activities of colostrum and milk from genetically susceptible sows, which protected their susceptible offspring in an outbreak of neonatal diarrhoea caused by K88-positive Escherichia coli, were compared with the activities in mammary secretions of resistant dams that did not protect their susceptible progeny. There was significantly more anti-adhesive antibody in the secretions of susceptible sows than in resistant sows, both during the disease period, and 1 year later. Fractionation of colostrum by gel filtration and ion-exchange chromatography led to identification of the anti-adhesive antibodies as including both IgA and IgM. 相似文献

In the first-litter sows lower serum levels were found for all three Ig classes as compared to multiparous sows. The same was true for IgA in lacteal secretions and in piglet serum during the first days of life, while no differences were found for IgG levels. In contrast to these findings, IgM levels were found to be higher in lacteal secretions of first-litter sows and in piglet serum during the first days of life as compared to their counterparts. From three weeks after birth Igs found in piglet serum mainly originate from de novo synthesis. In this period piglets of first litter sows showed a higher IgA level up to the 6th week of life and higher IgG and IgM levels up to the end of the investigation period. Results are discussed in terms of maternal-neonatal immune regulation, focussing on the apparent suppressive role of maternally-derived IgG on total de novo Ig synthesis by suckling piglets. 相似文献
