  The aims of present study were to evaluate the prevalence of mastitis, identify factors influencing disease incidence and test treatment methods in Phu Dong dairy farm in Gia Lam-Ha Noi. The results by California Mastitis Test showed that the prevalence of clinical mastitis was lower than that of sub-clinical cases (10.43% and 25.36%). Based on methylene blue decolorization test, 90% of testing milk samples could be used within 24 -48 hours. The percentage of milk samples discolorized by the dye within 30 minutes was 3.33%. The risk of infection was influenced by the stage of milking. The highest incidence was found in the first month of lactation then reached lowest point at fourth month. The infection rate continued to increase from sixth month toward the end of the lactation period. Age was positively correlated the disease incidence. Cows with higher levels of cross-bred rate had higher rates of mastitis. Treatment with neomycin/amoxicillin combined with pumping inside the infected udders and proper care was effective.

  Wild pigs are increasingly raised in Vietnam. However, documents related to the common reproductive diseases are rare. The present study aimed to investigate common diseases, determine the efficiency of preliminary treatment of metritis, and analyse the effects of postpartum metritis on the length of the interval from parturition to post-weaning estrus and post-weaning conception rate in wild sows. Overall, 102 wild sows from 5 farms were monitored. Results showed that common diseases in wild sows are metritis, mastitis, agalactiae and dystocia. Preliminary treatment of metritis with Lutalyse injection, Lugol and Neomycin infusion conferred very high cure rate. Wild sows with postpartum metritis have a significantly longer interval from parturition to post-weaning estrus, while their post-weaning conception rate is significantly lower compared with healthy sows. The present study showed that postpartum metritis is a common disease in wild sows, and it may hamper their reproductive performance.

  Besides observing the signs of clinical manifestations of 200 sows infected with metritis-mastitis-agalactia (M.M.A) syndrome in four provinces representative of the Red River delta in Vietnam, this study also investigated the hematological and biochemical parameters for comparison with clinically healthy sows. The research results showed that the clinical signs of sow group with M.M.A syndrome were similar to the manifestations of Pyrexia, restlessness, and anorexia The sows metritis-mastitis-agalactia (M.M.A) syndrome were not willing for the piglets to suckle or exhibited a marked disinterest in the piglets. The blood physiological and biochemical parameters indicated that the hematological indicators, such as number of red blood cells, hemoglobin concentration, corpuscular volume, corpuscular hemoglobin and corpuscular hemoglobin concentration of blood of sows with M.M.A syndrome group were higher than those from healthy sow group (P <0.05). In comparison with healthy sows, the number of white blood cell and neutrophils rate in blood of sows with M.M.A syndrome were higher. On the contrary, the rate of other types of white blood cells were lower (P <0.05). Albumin, total protein and β-globulin in the serum of sows with M.M.A syndrome group were lower than those in the blood of control sow group, whereas serum α - globulin và γ-globulin concentrations were higher. In addition, glicemia of M.M.A syndrome sows was decreasing, while enzymatic parameters (GOT and GPT activity) were increasing in comparison with the control group.
