THE PRODUCTIVE AND REPRODUCTIVE PERFORMANCES OF DAIRY COWS IN SUNAMGONJ DISTRICT MIAH, MD. SAYAD Bangladesh is a densely populated and agro-based developing country where most of the rural people are dependent for their livelihood mainly on cropping and livestock farming. Livestock sub-sector is playing a crucial role in the traditional subsistence farming, contributing about 6.5% of the GDP, 13% of the total foreign exchange earnings and providing employment to 20% of the population (BBS, 2004). The total cattle population of Bangladesh is 22.87 million of which 3.79 million is dairy cows yielding 1.64 million metric ton milk per year which is only 14% of the total requirement indicates the importance of the requirement for increasing the milk production in Bangladesh. Dairy cattle population in Bangladesh ranks 12 in the world and 3 th rd in Asian countries. About 92 percent of the dairy cattle is nondescriptive indigenous and only 8 percent is reported to be crossbred (BBS, 2006). The average milk yield per cow per day is 1.5 liters for indigenous and 2.5 liters for crossbreds. Dairying is nearly always part of a mixed farming system in Bangladesh (Saadullah, 2001). The majority of the rural households in Bangladesh have 2-3 dairy cows. Sometimes these cattle are used as dual purpose for milk and draft power.

ASSESSMENT OF HEMATOBIOCHEMICAL PROFILE OF POSTPARTUM CROSSBRED ANESTROUS COWS MONDAL, APURBO KUMAR Hemato-biochemical parameters are the key features of good physiological condition, where good physiological condition is the precursor of good production. For this reason the present study was aimed to observe the hemato-biochemical parameters of postpartum crossbred anestrous cows. The study was carried out during the period from January /2016 to June/2016. The objectives of the study aimed to assess the mean values of different hematological and biochemical profile of postpartum crossbred anestrous cows and determining differences among the mean values of different hematological and biochemical profile between cyclic and postpartum crossbred anestrous cows in the study areas. A total number of 30 crossbred cows weighing 220-250 kg were divided into two groups. Cows in group- A (target group) (n=15) were suffering from post-partum anestrous of more than 90 days. Cows in Group-B (control group) (n=15) were cycling cows of cross breed. Blood samples from cows with anestrous and cyclic were collected for hematological, biochemical and hormonal status analysis. T-test was performed to check the mean and standard error where confidence interval (CI) was 95%. All the analysis was performed at the 0.05 significance level. The Erythrocyte Sedimentation Rate (ESR) was not significantly lower and Hemoglobin (Hb %) percentage was significantly higher in anestrous cows than normal cycling control cows. Packed Cell Volume percentage (PCV %) in anestrous group of cows was significantly lower than that of control group of cows. The Total Erythrocyte Count (TEC) was significantly higher in anestrous cows than normal cycling control cows. The Total Leukocyte Count (TLC) in anestrous group of cows was significantly higher than that in the control group of cows. In Differential Leukocyte Count (DLC), neutrophil in anestrous group of cows was significantly higher showing the presence of an inflammatory process and eosinophil was significantly lower than that in the control group of cows. The mean total serum protein was not significantly lower in anestrous group of cows than that of control group of cows. The mean bilirubin concentration in anestrous group of cows was significantly higher than in control group of cows .The mean Serum Glutamic Pyruvic Transaminase (SGPT) and the mean Serum Glutamic Oxaloacetic Transaminase (SGOT) was significantly higher in anestrous group of cows than that of control group of cows. The mean values of progesterone, Follicle stimulating hormone (FSH) and Luteinizing hormone (LH) of anestrous cows were significantly lower than in control group of cows. It is suggested that there is no specific hematological and biochemical marker for anestrous in crossbred cows rather it may be hormonal cause for anestrous.

OBSERVATION OF HEMATOBIOCHEMICAL PROFILE OF BLACK BENGAL GOAT IN SYLHET REGION AKTER, AMENA Hemato-biochemical parameters are the key features of good physiological condition. Where good physiological condition is the precursor of good production. For this reason the present study was aimed to observe the hemato-biochemical parameters of Black Bengal goats reared under rural condition in three upazila namely sylhet sadar, golapganj and zokiganj of Sylhet district. The objectives of the study aimed to assess the mean values of different hematological and biochemical profile on the basis of age and sex and determining differences among the mean values of different hematological and biochemical profile of black bengal goats in the study areas. A total number of 90 goats were selected from study areas and 30 from in each upazila. Among them 30 were male and rest 30 were female. All the goats selected randomly. Apparently, healthy animal of three age groups used for hematological parameters like total erythrocyte count (TEC), total leukocyte count (TLC), packed cell volume (PCV), erythrocyte sedimentation rate (ESR) and hemoglobin (Hb) and various biochemical profiles like AST and ALT. Descriptive analysis was performed to check the mean and SE whereas One way Analysis of variance was performed to compare among the means. All the analysis was performed at the 0.05 significance level. There is no difference present in hematological and biochemical profile of black bengal goats among different study areas, as the p value obtained less than 0.05. Among age groups, there were differences present the TEC, TLC, PCV as the p value obtained less than 0.05. While for ESR no difference present as the p value obtained greater than 0.05. In case of male and female goats there are no differences in ESR, TLC, TEC, PCV as the p value obtained greater than 0.05. But Hb, AST and ALT were significantly differs as the p value obtained less than 0.05. It can be concluded that hematological and biochemical parameters increase with the increasing of ages and higher in male than female.

EFFECTS OF WATER SOLUBLE BLOOD MEAL ON GROWTH PERFORMANCE AND HEMATOLOGICAL PARAMETERS IN BROILERS

EFFECTS OF WATER SOLUBLE BLOOD MEAL ON GROWTH PERFORMANCE AND HEMATOLOGICAL PARAMETERS IN BROILERS ALAM, MD. ROWSHAN The experiment was conducted to investigate the effects of blood meal supplement on growth performance and hematological parameters in broiler chicks. The experiment was carried out with 60 selected homogenous sex and weight broiler chicks having 15 for each group. The layout of the study was conducted with control group A, fed only with standard commercial broiler ration and other groups viz. B, C, and D were fed with standard commercial ration in addition to 2.5 %, 5.0 %, and 7.5% of blood meal. The activities of broiler chicks, growth performance, weight loss or gain and any kind of abnormalities were closely observed in every day and the body weight was recorded at 7 days interval. During feeding of blood meal all treated groups were found increased body weight at different level. The blood meal supplied to the broiler chicks increased the growth performance that was directly proportionate to the rate of blood meal supplement with water, because the ration was fixed for every group. In hematological observations, TEC, Hb concentration and PCV were decreased but rap id decreasing occurs in group (B) that was statistically significant (P<0.05). In this experiment during feeding of blood meal no clinical symptoms were found markedly. But slight symptoms occur when fed 7.5 % blood meal. The data were analyzed by least significance difference (LSD) with a computer program SPSS-11.50 (Statistical packages for social sciences).
