The Pabna is one of the potential local cattle breeds in Bangladesh regarding milk production and its nutritive quality. The aim of the study was to know the effect of lactation length, parity and management on production performance and nutritional/physiochemical composition of the milk of local Pabna cows. Besides the regular milking, 15 days’ interval test day milking was recorded from 12 local Pabna cows with different lactation period (up to fifth month of calving) from BLRI Regional Station, Baghabari during January-September, 2018. In addition, 12 and 16 milk samples (200 ml/sample) were collected from the cows raised at BLRI Regional Station and the community of Dairy Development Research Project at Bera, Pabna district during June, 2018, respectively. Data were analyzed in an ANOVA of Completely Randomized Design and independent sample t-test, respectively, using SAS version 9.1.3 (SAS Institute Inc., Cary, NC, USA) including Tukey’s HSD post hoc test to separate means. The average daily milk yield was significantly (p<0.05) higher during the first month (4.62 L) of lactation and the lowest value recorded at 5th month (3.50 L). Among the test days milking better yield observed at 15 days (4.79 L) of experimental lactation period (p<0.05). The effect of lactation stages and parity number had no significant variations (p>0.05) on nutrient compositions of local Pabna cows’ milk in both on-station and community. However, the overall characteristics of milk between on-station and community had significant differences on the composition of total solids (p<0.001), SNF (p<0.001), fat (p<0.01), and protein (p<0.05) where the highest values found as 14.81, 8.65, 6.17 and 3.53% at on-station, respectively. The first month of lactation observed as best milk producing period among the five months and the management system had positive association with milk composition of local Pabna cows. Asian J. Med.

Selection is one of the vital tools for improving the indigenous chicken genetic resources. A total of 1585-day-old chicks comprising of 3 types of chicken namely Naked Neck (NN), Hilly (H) and Non-descript Deshi (ND) were hatched for this study to form foundation stock. Improvement target of egg weight was to increase by 1g and improvement target of egg production rate was to increase by 2 % per generation. In foundation stock, selection was practiced at 40-week of age, on the basis of an index comprising the parameters of age at first egg (ASM), body weight(BW), egg production(EP) and egg weight(EW). Data were analyzed in CRD by General Linear Model (GLM) Univariate Procedure. Significantly highest fertility (82.71%) and hatchability (82.20%) were found in ND genotype. Significantly (P<0.001) highest body weight of day-old chicks and daily weight gain was found in H genotype than other two genotypes. There was a non-significant (P>0.05) variation in FCR among the native chicken genotypes. NN genotype (3.46%) had non-significantly (χ 2 = 3.62; P > 0.05) higher chick mortality than ND (1.63%) and H (2.11%) at brooding period (0-4 weeks). Significantly (P<0.01) higher dressing percentage was found in NN (64.58) genotype than ND (60.26) and H (61.70) genotypes. Non-significantly higher egg production in selected group was found in H (70) genotype than ND (68) and NN (67) genotypes. Significantly (P<0.001) highest shape index and Haugh unit were found in H and ND genotypes, respectively. As a result of selection, egg production is expected to improve by 0.562, 0.932 and 0.755%, respectively for ND, H and NN genotypes. In terms of reproductive traits ND was superior, in terms of productive traits H genotype was superior and in terms of dressing percentage and breaking strength NN genotype was superior. These findings of the study also give an impetus for continuing the research for more generations to fulfill the objectives of the long-term programme.

The present study was conducted at milk pocket areas Sahjadpur Upazila under Sirajgonj district and Shathia and Bera Upazila under the Pabna district, respectively. A total number of one hundred ninety (190) dairy farmers were surveyed randomly selecting twenty farmers from each village. All data collected were statistically analyzed using Univariate General Linear Model (GLM) procedure of SPSS computer program. Lack of balanced feed was the highest cause of repeat breeding claimed by about sixty (60%) percent farmers in this study. The highest incidence of RB was obtained in LocalHolstein Friesian crosses (69%) and lowest in LocalSahiwal crosses (8%). From the study of present findings; it can be concluded that genotype, nutrient of feed, quality of semen, frequency of insemination and reproductive problems are the main possible causes for RB in the studied areas.

Abstract:The study was conducted on Bergobindapur baor at Chaugachha upazila under Jessore district. The study period was February to June, 2015. Data were collected by using participatory rural appraisal (PRA) tools and personal observation. Net return was loss in 2013-2014 and the loss amount was BDT 254200. Cost benefitratio in 2013-2014 was 0.99. Major income (83.30%) of the fishermen community was drawn from the fishery activities of Bergobindapur baor. In 2014-2015, average income of fishermen was BDT 25250 during the fishing period. Within the household of fishermen community, the expenditure for food was 19%, clothing, 3%, children's education, 19%, medical, 3%, dowry and religion, 33%, agriculture, 13% and others, such as business, accommodation, sanitation etc. 10%, which came from baor activities. The findings of this study indicated that Bergobindapur baor plays a vital role for the support of livelihood of fishermen and net profit from baor was not satisfactory. A long-term strategy should be developed to make the baor profitable. The developed strategic plans should be initiated immediately for the profitability of the baor as well as improving the livelihood conditions of the fishermen engaged with the boar fishery activities.Keywords: economic analysis; baor fishery activities, impact on fishermen IntroductionJessore district has a large number of ponds, rivers, marches, baor, beel and total fish production from Jessore was 70426 MT during 2010 -11 (BBS, 2013. A baor is ox-bow lake, which is the still part of the flood plain of river connected by inlets and outlets. By screening the inlets and outlets a baor can be converted into a culture based fishery (DoF, 1996). Fisheries sector employed about 1.3 million full time fishermen and 12.5 million part times (DoF, 2013). Livelihood support could have various meanings, ranging from livelihood provision, to protection, recovery and promotion (Maxwell, 1999). The average rate of production from baor was 633kg/ha which can be increased manifold (DoF, 2011). Abdullah-Bin-Farid et al. (2013 found that socio-economic conditions of fishermen of the Baluhar baor was 58% lived in joint families, 78% used kancha (un-hygenic) sanitary latrine, 58% having 0.041 hectare lands and 74% lived in kancha (earthen) house. Das (2014) reported that total benefit from Bergobindapur baor was BDT 7135363.5 in the year 2012-13. From the above reviews, it was understood that the study on baor was limited and there were no research works about how baor had impacts on rural fishermen in the aspect of Bangladesh. Thus the present study was very important and it will

Abstract:The improvement of productivity of indigenous chicken is a long desire in the country. Present research is a part of the long-term selection program being undertaken to evaluate the carcass characteristics and expected response to selection of second generation (G 2 ) of indigenous chicken under intensive management in Bangladesh. A total of 1643-day-old chicks comprising of 3 types of chicken namely Naked Neck (NN), Hilly (H) and Non-descript Desi (ND) were hatched in a two batches for this study. In second generation (G 2 ), selection was practiced at 3 (three) stages of birds life, firstly and secondly at 8 and at 16 weeks of age, selection was performed on the basis of breeding value for 8 and 16 week body weight. Thirdly, at 40-week of age, on the basis of an index comprising the parameters of age at sexual maturity (ASM), body weight (BW), egg production (EP) and egg weight (EW). Improvement target of egg weight was to increase by 1g and improvement target of egg production rate was to increase by 2 % per generation. The main target was the mean body weight in H, ND and NN chicken has to be gone up from the initial eight-week body weight of 375, 342 and 331g to 500 g at eight weeks of age. At 8, 10 and 12 weeks of age, six birds from each genotype were slaughtered to analyze the meat yield traits. Slaughter data were analyzed in a 3 (genotype) × 3 (slaughter age) factorial arrangement in CRD by General Linear Model (GLM) Univariate Procedure in SPSS Computer Program. Genotype and slaughter age had significant effect (p<0.001) on dressing percentage. Body weight at 8 weeks of age was expected to improve by 51.21 vs. 24.03; 37.74 vs. 15.47 and 26.26 vs. 9.65g; respectively for ND, H and NN males and females. In terms of body weight H genotype was superior and NN genotype was for dressing percentage. As a result of selection; EP, BW increased and ASM reduced in second generation than that of the foundation stock.
