  The aim of this study was to determine the changes of somel hematological parameters in experimental coccidia-infected Luong Phuong chicken caused by Eimeria tenella. Fourty coccidia-free chickens were selected, raised in clean cages and were periodically screened for Eimeria infection status by microscopical fecal examination. Two weeks later, the chickens were distributed into 2 groups, experimental and control groups, 20 chickens in each. The experimental group was inoculated orally with sporulated oocyst of E. tenella at the dose rate of 1 105/chicken, while control group was given orally PBS solution. After one week, all chickens were bled by cardiac puncture to determine hematological parameters. The results indicated that number of erythrocytes, hemoglobin volume, and hematocrit decreased. In contrary, the mean corpuscular volume increased, while mean corpuscular hemoglobin, mean corpuscular hemoglobin concentrations and red cell distribution width remained unchanged. The number of leukocytes increased and its formula was changed, number of neutrophils and eosinophils increased, in the case of lymphocytes decreased. The total protein of serum, its formula and A/G ratio decreased and the formula of corpuscular globulins were also changed as compared with control group chickens.

  The study was conducted to evaluate hematological parameters, persistence of antibodies against African swine fever virus (ASFV), and growth performance of D × DLY crossbred pigs, from Duroc boars and Duroc × (Landrace × Yorkshire) survivor sows infected by ASFV. Ear tattoos and ear tags were applied to the piglets at birth and weaning, respectively. At 2, 3, 4, 5, 6, and 7 months of age, body weight of each animal was recorded, and blood samples were collected for hematological and immunological analyses. The results showed that antibody levels remained positively throughout the study period (from 2 to 7 months of age). Red blood cell counts ranged from 6.07 to 7.82 T/L, hemoglobin levels from 9.77 to 11.26 g/dL, platelet counts from 284.71 to 344.70 G/L, and white blood cell counts from 17.43 to 23.78 G/L. Most hematological parameters in pigs born from ASFV survivor sows were within the normal range, though they tended on the lower range of the reference intervals. Body weights at 2, 3, 4, 5, 6, and 7 months of age were 13.5, 30.88, 43.86, 65.33, 81.94, and 99.33 kg, respectively. The growth performance of D × DLY crossbred pigs was lower than normal animals.

  This study aimed to evaluate the effect of dietary nanocurcumin on growth performance, carcass yield, meat quality and blood physiological parameters of Ross 308 chicken. A total of 120 one-day-old Ross 308 chickens were randomly allocated into two treatments: (1) control group fed basal diet and nanocurcumin group feda basal diet supplemented with 200 mg nanocurcumin per kg. Each group was replicated three times. The results showed that supplemntation with nanocurcumin in the diet did not affect the survival rate, daily gain, body weight, daily intake, carcass yield and meat quality (P >0.05). The feed conversion ratio in nanocurcumin group (1.32) was lower than in the control group (1.36) (P <0.05). Proportions of abdominal fat, the weight of the liver, heart and spleen were not different between control and nanocurcumin groups (P >0.05). Dripp loss, pH and meat tenderness did not significantly different, except b* values of breast (P <0.05). Hematological parameters in nanocurcumin group were higher than those in control group (P <0.05), except lymphocytes proportion.

  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.

  The present study was conducted to evaluate the effects of dietary co-supplementation of peptidoglycan and probiotics on growth performance, survival, feed utilization, and hematological parameters in Nile tilapia. Commercial feed specialized for tilapia were supplemented with peptidoglycan and probiotics at various concentration (g/kg of diet): 0; 3+3; 5+3; 5+5; 3+5 corresponding to experimental treatments: NT1, NT2, NT3, NT4, NT5. Nile tilapia juveniles were fed on the experimental feed for 4 weeks at a ration of 5% body weight; the feed amount was daily recorded. During the feeding period, fish were weekly weighed to monitor the fish growth. After a 4-week trial, blood samples were collected for hematological analysis; the fish number and weight were used to determine the survival rate and fish growth. Results show that the co-supplementation of probiotics and peptidoglycan induced positive effects on the fish survival, growth, and feed conversion ratio, in which fish fed 3g peptidoglycan + 3g probiotics displayed the best results.

  The purpose of this study was to assess the prevalence of Theleiriaspp. on dairy cows in Ha Nam province, as well as to examine various hematological markers in cows infected with Theleiriaspp. Theileriaspp. were found on dairy cows grown in Ha Nam province using the giemsa staining procedure. A total of 190 blood samples were collected from HF bovines in three districts,Duy Tien, Kim Bang and Ly Nhan, of which26 samples were found to be infected with Theleiriaspp. by Giemsa staining method, accounting for 13.68%. Evaluation of hematological indices of cows infected with Theileriaspp. demonstrateda slight decrease in bothnumber of red blood cells (RBC) and hemoglobin (Hb) levels in blood samples of dairy cows over 2 years of agewhilethe total white blood cell count (WBC) index increased significantly, the neutrophils, lymphocytes, and monocytes only showed slight increases while the platelet count (PLT) decreased sharply. The results showed that there was a change in the hematological index of cows infected with Theileriaspp.The findings of this study provide a foundation for the use of blood tests in diagnosing, prognosing, and treating cattle with Theileriaspp. infection.
