Abstract:Contagious ovine pleuropneumonia, also known as mycoplasmal pneumonia, is a highly contagious infectious disease caused by mycoplasma. Its clinical features are high fever, cough, and serous and fibrinous inflammation of the chest and pleura. The disease mainly affects lambs aged 1 to 3 months. It often takes acute and chronic forms and has a high mortality rate. It is a common respiratory disease in sheep breeding. Antibiotics are mostly used for clinical treatment, but drug resistance often occurs, resulting in poor efficacy. In recent years, we have used early application of Chinese herbal medicine supplemented with more sensitive antibiotics for treatment, and achieved good therapeutic effects. This article observes the efficacy of four commonly used groups of traditional Chinese medicine prescriptions and selects a group of Chinese medicine prescriptions with the best efficacy, in order to provide solutions for clinical treatment.

Abstract:Hu sheep breeding has formed an industrial chain in China, which is of great significance to effectively link poverty alleviation to rural revitalization. However, in the production practice, it was found that the Hu sheep produce more lambs, have low survival rate, and grow slowly, and have a high incidence rate because of ewe mastitis. In recent years, forced supplementary feeding technology has been adopted to exercise the digestive system of lambs in advance, and good results have been achieved. This study carried out a comparison of two forced supplementary feeding methods of concentrate and concentrate + forage in a largescale Hu sheep breeding farm, and made a comparison from the growth rate, growth and development of digestive tract, slaughter performance and histomorphology of gastrointestinal tract of lambs. Results showed that the effect of early forced supplementary feeding of concentrate + forage was significantly better than that of concentrate alone. The research results are of great significance for the largescale Hu sheep breeding farm to improve the survival rate of lambs, reduce the incidence rate of ewe mastitis, and promote the quality and efficiency of Hu sheep breeding.

Abstract:This study used Cryptosporidium spp. 18S rRNA as the target gene, and found that 18 of the 101 fresh fecal samples collected were positive through nested PCR detection. The Cryptosporidium infection rates in sheep farms in different areas were 36% (18/50) in Liji Town, 0% (0/30) in Xin'an Town, and 0% (0/21) in Duigogang Town. No Cryptosporidium was detected. However, through the analysis of 4 sheep farms, it was found that 2 sheep farms (50%) were positive for Cryptosporidium infection, and the infection rates of different sheep farms were significantly different. Therefore, the infection rate of Cryptosporidium was simply evaluated by region, is debatable. The infection rate of Cryptosporidium parvum in goats was 33.3%, and the infection rate of Cryptosporidium parvum in Hu sheep was 2%. The infection rate of Cryptosporidium parvum in fattening sheep aged 2 to 6 months was 36%, and that of growing sheep aged 6 to 10 months (0%). The Cryptosporidium 18S rRNA gene fragment sequence analysis was performed on the samples that tested positive. We found that all 18 samples were Cryptosporidium xiaoi and there was no Cryptosporidium ubiquitum. In 1 goat farm and 1 Yanghu sheep farm that tested positive for Cryptosporidium infection, there was Cryptosporidium parvum infection, but there was no Cryptosporidium ubiquiti, and no Cryptosporidium parvum and Cryptosporidium ubiquita were found. of mixed infections. Current data suggest that Cryptosporidium shooni has a higher infection rate in goats aged 2 to 6 months (33.3%) and Hu sheep (2%). These 18 samples came from two largescale sheep farms, belonging to two sheep farms in Liji Town.

Abstract:This study aims to understand the prevalence of porcine reproductive and respiratory syndrome (PRRS) in Jiuquan City. This experiment collected 638 samples from five agricultural counties and cities in Jiuquan City, and used reverse transcriptionpolymerase chain reaction (fluorescence RTPCR) method for nucleic acid detection. We analyze the prevalence in different regions, different growth periods, and different feeding modes. The results showed that a total of 29 PRRS nucleic acid positive samples were detected among 638 samples, and the PRRS positive infection rate was 4.55%. The PRRS positive infection rate in different regions ranges from 0-7.95%. The PRRS positive infection rates in slaughterhouses, largescale farms, and freerange households were 0, 2.96, and 6.82% respectively. The PRRS positive infection rates of breeding boars, fattening pigs, piglets, and sows were 0, 3.1, 5.38, and 6.36% respectively. The results showed that PRRS was sporadic in Jiuquan City. Largescale farms are highly standardized and have advanced feeding and management models with low PRRS positive infection rates. Piglets and sows are more susceptible to this disease. This test will provide technical support for the comprehensive prevention and control of PRRS in our city.

Abstract:Cow abortion is a common issue in dairy cattle farming. If not actively prevented and treated promptly, it can lead to extended breeding cycles and reduced calving rates, thus causing significant economic losses to the livestock industry. This study analyses cases of cow abortion that occurred on a specific cattle farm between October 2022 and September 2023. The statistical results revealed that out of 29 reproductively capable cows, 29 calves were born, but unfortunately, 9 of the newborns died, resulting in an alarming abortion rate of nearly onethird. To identify the underlying causes of these abortions, this research conducted comprehensive investigations and tests on various factors, including environmental conditions, feed quality, and medication practices. The study revealed severe contamination of silage feed with mold and a significant excess of Aflatoxin B1. Considering these findings and the overall examination, the preliminary conclusion points to prolonged consumption of Aflatoxincontaminated feed as the fundamental cause of cow abortions. To mitigate the abortion rate, this study proposes a series of targeted preventive and control measures. These measures include monitoring animal health, regulating feed management, and conducting regular tests for mold toxins. The objective is to minimize the incidence of cow abortions and provide valuable assistance to fellow professionals and cattle breeders.

Abstract:Experimental teaching is the core link in the teaching system of veterinary medicine, and experimental reports are an important carrier for students to master experimental principles, analyze experimental phenomena, and write experimental results. This is an integral part of experimental teaching. Currently, in the experimental teaching process of veterinary subjects, paperbased experimental reports are used as the main assessment mode for experimental courses. There are problems such as the inability to reproduce the dynamic experimental process and the inability to objectively and truly describe experimental phenomena in text. Traditional paperbased experimental reports can no longer meet the current teaching needs of college students. In the process of experimental teaching in veterinary subjects, most animal experimental phenomena cannot be properly described in words. Digital methods such as pictures, videos, and animations can more intuitively display the pathological changes in organs before and after the onset of animal diseases. This helps students deepen their experimental skills and professional knowledge by writing experimental reports. On this basis, a teaching model of digital experimental reports was proposed and promoted and applied in actual teaching practice. Through the implementation of digital experimental reports, students' experimental teaching classroom response has been good, and the teaching quality has been significantly improved. This article is summarized here. This is expected to provide a reference for improving experimental teaching methods and improving teaching quality.
