The present study was carried out to investigate the haemato-biochemical profile during different stages of lactation in local Sahiwal crossbreed dairy cows at Savar area of Dhaka district of Bangladesh. Twenty four local Sahiwal crossbreed cows were selected randomly from different small farms and divided into three groups: early stage lactation (1-3 months), mid stage lactation (4-6 months) and late stage lactation (7-9 months). Blood samples were collected during three stages of lactation. There were no statistical significant (p<0.05) variations observed in hematological parameters amongst the three stage of lactation. Although the packed cell volume (PCV), hemoglobin (Hb) concentration and RBC count were found lowest in early stage of lactation than the other groups. Total leucocyte count (TLC), platelet count (PLT), mean corpuscular volume (MCV) and mean corpuscular haemoglobin (MCH) were recorded within normal limits. Similarly, biochemical parameters were observed statistically non-significant amongst the groups studied. The glucose level was recorded lowest in early stage of lactation; whereas, the protein and creatinine concentrations were slightly higher in this stage. Aspartate aminotransferase (AST), Alanine aminotransferase (ALT) and Alkaline phosphatase (ALP) were not varied amongst the three groups of cows. Data generated during the current study may be useful as reference values for the scientific community. Asian J. Med. Biol. Res. March 2021, 7(1): 1-5
The present study was carried out to investigate the physiological comparison of some serum biochemistry between lactating and non-lactating dairy cows in selected dairy farms of Dhaka district of Bangladesh. The aim of the current study was to evaluate the serum parameters like glucose, total protein, total cholesterol, calcium and phosphorus concentration and these parameters were measured by the serum analyzer for lactating (n=50) and non-lactating (n=50) dairy cattle which were selected from various selected dairy farms of Dhaka district. The results (mean ± standard deviation) of the study showed that among the serum biochemical parameters total protein (84.2±1.18 gm/l) and total cholesterol (156.36± 3.41 mg/dl) level in non-lactating cows were higher than the value of lactating cows as (80.14±2.31 gm/l) and (138.21± 1.21 mg/dl). On the other hand, serum glucose, calcium and phosphorus level in lactating cows (68.12± 2.34 mg/dl), (12.06±3.21 mg/dl) and (8.30±0.20 mg/dl) respectively were found higher than the non-lactating cows (60.32 ±1.42 mg/dl), (10.48±5.60 mg/dl) and (6.31 ±0.12 mg/dl). In case of parity-wise biochemical parameters were insignificant variation was found. It may be concluded that biochemical parameters variation present between lactating cow and non-lactating cow is important for interpretation of laboratory data and also for physiological diagnosis.
Hemato-biochemical parameters aid in the formulation of effective treatment and supportive therapy for infectious diseases of animals such as peste des petits ruminants (PPR). The present study investigated the prevalence of PPR in Black Bengal goats reared in Jaintapur, Sylhet and concurrent hematology, liver and kidney function tests of PPR infected goats. Information of PPR infected goats was recorded according to age and sex by asking questions to the owner or farmers. Blood samples from 10 PPR-infected Black Bengal goats and 10 normal healthy goats were collected and analyzed using routine blood and biochemical tests. PPR positive cases were found in 60 of 125 goats examined based on clinical signs. The highest prevalence (50%) was recorded in young goats (below 12 months) followed by goats of 12-24 months of age and older goats (above 25 months). Older goats were less susceptible to PPR infection. Male goats were less susceptible to PPR infection (31.66%) compared to female goats (68.33%). PPR is more likely in goats with lower body condition score (BCS). PPR-infected goats had macrocytic hypochromic anemia, as evidenced by significantly lower TEC, Hb, and PCV levels and higher MCV and MCH levels. The total leucocyte count (TLC) was significantly (P<0.05) decreased, neutrophils numbers were significantly increased but lymphocyte numbers were decreased in PPR infected goats. ALT, AST and creatinine reflect the liver and kidney functions. PPR-infected goats had significantly higher (P<0.05) AST, ALT and creatinine values than normal healthy goats. A high level of AST and ALT in PPR-infected goats might be due to liver damage. The high creatinine level indicates functional damage to the kidney. In conclusion, Prevalence of PPR in higher in Black Bengal goats reared in Jaintapur, Sylhet and PPR virus altered the hematological parameters and liver and kidney function test of the PPR infected goats.

Objective: The study was carried out to determine the reproductive performance of Black Bengal (BB) goats in the selected industrial and nonindustrial areas of Bangladesh. Materials and Methods: The data were collected from 200 farmers using a pretested questionnaire. The questionnaire contained primary information about the reproductive performances, such as age at puberty, conception rate, postpartum heat period, kidding interval, litter size, estrous behavior and interval, abnormalities during pregnancy and parturition, kid mortality, developmental abnormalities, total number of goats, and goat rearing system. Results: The data showed that the average age at puberty and conception rate of BB goats in the industrial areas were 188.20 ± 2.372 days and 88%, respectively, whereas the values were 164.70 ± 2.077 days and 96%, respectively, in the nonindustrial areas. The data significantly differed (p < 0.05). The average estrous cycle and kidding interval of BB goats also differed significantly (p < 0.05) between the industrial (21.50 ± 0.824 and 205.80 ± 1.445 days, respectively) and nonindustrial areas (17.50 ± 0.479 and 189.40 ± 0.922 days, respectively). However, the average litter size of goats in the two areas did not differ significantly (p > 0.05). The average kid mortality rate was higher in industrial areas (14.0% ± 0.155%) than in nonindustrial areas (8.5% ± 0.118%). Conclusion: BB goats reared in industrial areas have lower reproductive performance than those raised in nonindustrial areas. Factory pollution may be one of the main reasons for reducing kids in BB goats.
