Spatiotemporal pattern of peste des petits ruminants and its relationship with meteorological factors in China

Peste des petits ruminants (PPR) is a severe infectious viral disease of domestic and wild small ruminants, and it threatens food security and livelihood of farmers across the world. In China, 292 PPR cases have been reported since it was first reported in 2007. Aiming to display the spatiotemporal patterns of PPR outbreaks and to understand its relationship with meteorological factors, we conducted a direction test, directional distribution analysis, and logistic regression analysis. The results showed that the spread of disease had a significant directional spread (P<0.05). Daily average temperature (DAT) [OR 0.063 (95% CI 0.047-0.076)], daily average relative humidity (DARH) [OR 0.871 (95% CI 0.804-0.944)], and daily hours of sunshine (DHS) [OR 0.411 (95% CI 0.389-0.582)] were inversely associated with the risk of PPR outbreak, while a positive association was observed for daily average air pressure (DAAP) [OR 1.211 (95% CI 1.036-1.417). Our findings indicate that meteorological factors may be important variables for affecting PPR transmission, and should be taken into account in the future monitoring programs for PPR.

Design and Implementation of Stud-farm Daily Management System Based on C/S Structure

In order to achieve the computerization and digitization of the daily system of stud-farm, the immunization system technology, racecourse health monitoring technologies and the stud-farm prevention technologies were combined to built the stud-farm daily management system. By using Visual Studio 2008 and Microsoft Office Access 2003, an immunization information system was developed based on Client/Server structure and combined with the key immunization link of horses. The system included stud-farm immune management and racecourse health monitoring system. The immune management contained immunization information input, the inquiry of immunization information, immunization statistics, immunization-reminding and system management. The racecourse health monitoring system included stud-farm monitoring, horses monitoring and inquiry and statistics of health monitoring. The software realized the analysis and tips of the daily information in stud-farm. The software could record the appropriate data and carry on the statistics. The stud-farm daily management system greatly improved the efficiency of the expanded program about immunization and horses’ healthy rearing technique.

Laparoscopic Embryo Transfer in Pigs: Knowledge for Surgical Procedures

Abstract The objective of the study was to describe and improve a technique for laparoscopic embryo transfer into the oviduct and uterine horns of pigs and to evaluate the feasibility and safety of this method. Fourteen female pigs were randomly allocated into groups A and B: three portals were used for group A, and the simulation of embryo (0.9% NaCl, 0.2 mL) was injected into the tip of uterine horn; three or four portals were used for group B, and the injection set of the oviduct was inserted through the abdominal orifice of uterine tube into the oviduct to inject the simulation of embryo. The repeat laparoscopy was performed on the 21st day. Three pigs randomly selected from each groups were repeated the same procedure three times, and then were euthanized on the 21st day after the last surgery and a complete necropsy performed. Laparoscopic embryo transfer was performed successfully in all pigs without major intra-and post-operative complications. The average surgical time which accomplished procedures for groups A and B was 18.6 min (range, 28−14 min) and 37.4 min (range, 53−29 min). Postoperatively, none of pigs appeared to abnormal signs. This study demonstrated that laparoscopic embryo transfer could be easily accomplished by using the special-purpose equipment and increasing reuse time of a female recipient.

Effect of Atipamzole on Fos Protein Expression Induced by Telazol/Xylazine in Rat Cerebral Cortex and Thalamencephal

Abstract The aim of the study was to assess effect of the atipamezole on talezol/xylazine induced expression of c-fos in rat brain. Rats were injected with the mixture of 13.81 mg · kg −1 telazol and 5.21 mg · kg −1 xylazine, following 10 min later 0.522 mg · kg −1 atipamezole injected, and then the cerebral cortex and thalamencephal were removed at 1 h after injected. Level of Fos protein was measured in the brain tissue by western-blot. The results revealed that telazol/xylazine induction Fos protein expression in the thalamencephal and cerebral cortex during the period of anesthesia, atipamezole attenuated telazol/xylazine induction Fos protein expression in the thalamencephal and cerebral cortex. The results indicated that atipamezole could inhibite telazol/xylazine-induced c-fos expression in the rat brain, and played a protective role of neuronal injury.

Atipamezole Attenuated Telazol/Xylazine-Induced Expression of C-Fos in Rat Thalamencephal and Cerebral Cortex

Abstract The aim of this study was to assess whether atipamezole can restrain telazol/xylazine induced expression of c-fos in the rat brain. Rats were injected with a mixture of 13.81 mg/kg telazol and 5.21 mg/kg xylazine, following 10 min later 0.522 mg/kg atipamezole. Thereon, the thalamencephal and cerebral cortex were removed one hour after the last injection. The level of Fos protein was measured in the brain tissue by Westernblot. The results revealed that atipamezole attenuates telazol/xylazine induction of c-fos expression in the thalamencephal and cerebral cortex. The results indicated that atipamezole is able to inhibit telazol/xylazine-induced c-fos expression in the rat brain, thus protecting it from nerve damage.

The Fuzzy Model for Diagnosis of Animal Disease

The knowledge of animal disease diagnosis was fuzzy; the fuzzy model can imitate the character of clinical diagnosis for veterinary. The fuzzy model of disease, the methods for class the disease group of differential diagnosis and the fuzzy diagnosis model were discussed in this paper.The knowledge of animal disease diagnosis was fuzzy; the fuzzy model can imitate the character of clinical diagnosis for veterinary.
