    Abstract: This study was aimed to evaluate milk urea nitrogen (MUN) of cows considering variations in dietary nutrition, genetic quality and lactation yield which will be helpful to develop practical feeding guidelines for dairy cows based on MUN. A total of forty dairy cows consisting 20 native and 20 crossbred milking cows were selected in Sonaimuri, Noakhali in winter season to know the daily feed availability to cows. Feed, milk and blood samples were collected and analyzed. The dry matter intake of the local and crossbred cows were 2.58 and 2.74 (g/100 kg live weight respectively) and they did not show statistical variation (p 〈 0.05). Metabolizable energy (ME) and protein intake showed significantly higher values in crossbred (85 MJ/day and 815 g/day) compared to local (40 MJ/day and 395 g/day) cows in winter season (p 〉 0.05). Live weight, body condition score and milk yield and MUN varied significantly between genotypes although blood urea nitrogen (BUN) value did not differ significantly. Strong correlation between lactose and protein percentage was observed in both the lactations in local cows. Milk minerals are negatively correlated with protein, SnF and minerals in first lactation whereas moderate to strong relation was observed in second lactation with those parameters. Milk constituents didnt show any difference between local & crossbred cows. Strong correlation between milk protein and lactose with SnF were observed in both local and crossbred cows in first lactation stage. BUN value showed a moderate correlation between milk yields of local cows. The results revealed that genotype and lactation have no effect on BUN although MUN value showed significant difference between local and crossbred cows.Bangladesh J. of Livestock Res. 19(1-2): 74-84, Jan-Dec 2012

    Abstract: The present study was conducted at Bangladesh Livestock Research Institute, Savar, Dhaka to assess the performances of three Indigenous Chicken genotypes under intensive management. A total of 1128-day-old chicks comprising of 3 types of chicken namely Naked Neck (NN), Hilly (H) and Non-descript Deshi (ND) were hatched in one batch for this study. Significant (p 〈 0.001) body weight differences among the genotypes were observed at 12th and 16th weeks of age, with the highest body weight observed for H genotype (1250.71±27.71, and 1502.54±36.81g) among the other two genotypes. NN genotype (2.85%) had significantly higher chick mortality than ND (0.68 %) and H (2.08 %) genotypes at 0-8 weeks of age. The age at first egg laid was significantly (p 〈 0.001) affected by genotype. The age at which Indigenous Chickens start laying eggs ranged from 152.79 to 161.95 days. The Hen-day egg production (HDEP%) observed in the present study were affected significantly (p 〈 0.001) by genotype. In this study, the average HDEP% of ND, H and NN were found to be 38.44±2.18, 30.43±2.10 and 41.95±2.11. Eight week body weight of males ND, H and NN birds were expected to increase by 64.7, 46.1 and 43.9g, respectively. While in females ND, H and NN birds, the expected responses were 21.5, 27.9 and 10.7g, respectively Bangladesh J. of Livestock Res. 21-25: 153-158, 2018

    Abstract: This research was aimed to improve the egg production performances and to estimate the selection response of fifth generation (G5) of deshi white (Rupali) and white breasted black (Nageswari) duck genotypes through an individual selection program. All the ducks were reared in an open sided duck house. Diet containing 17.5% CP and 2750 Kcal ME/kg and fresh water provided twice daily in the morning and evening. Individual egg production was recorded from each duck. After 40 weeks of age, female ducks were selected on the basis of selection index and selection differences, selection intensity and responses were also measured. Egg weight, egg production and feed intake were recorded and FCR, egg mass was calculated. All recorded data were analyzed by SAS and differences were determined by DMRT. The selection criteria of fifth generation (G5) of both duck genotypes were studied. As a result of selection, age at sexual maturity (day), egg weight (g) and egg production % were expected to improve by -1.63d, 0.60g, 1.01% and -0.85day, 0.39g, 0.47% for Rupali and Nageswari ducks, respectively. Egg mass was significantly (p 〈 0.05) higher in Rupali (40.24g) than Nageswari (37.55g) duck whereas, egg weight was not significantly differ in both genotypes. Egg production in Rupali and Nageswari duck was 65.41% and 62.74%, respectively. Rupali ducks were significantly (p 〈 0.05) consumed more feed (134.54 g) than Nagesswari ducks (126.23 g). The FCR was significantly (p 〈 0.05) better in Rupali (3.34) than Nageswari (3.61) ducks. The egg quality results showed that egg shell thickness of Rupali duck was significantly (p 〈 0.05) higher than Nageswari. Higher values for albumen width (p 〈 0.05) was also found in Rupali (65.03mm) than Nageswari (59.11mm) duck egg. On the other hand shape index, albumen index, yolk index and haugh unit were not found significantly different in both genotypes but the yolk color score of Nageswari found highest score than Rupali duck egg. Proximate composition of eggs was not significantly different of both duck genotypes. Based on the results it is revealed that Rupali duck was better in terms of egg weight, egg mass and egg production, but starting lay egg is earlier in Nageswari than Rupali duck. Bang. J. Livs. Res.

    Abstract: The poultry feed, meat and egg samples were collected from the major poultry raising areas of the country to know the presence of heavy metals especially arsenic (As), lead (Pb) and chromium (Cr). A total of 360 elemental samples for As, Pb and Cr were analyzed in the laboratory. The heavy metal contents (As, Pb & Cr) of all the tested samples were found positive. But, the levels were below the Maximum Permitted Concentration (MPC) in most cases. The layer and broiler ready feed samples found safe from those elements; On the other hand, the “Cr” and “Pb” content in 14% and 11% loose feed samples were 7-70 and 3 times respectively higher than that of MPC. Notes worthy, the egg samples were also found safe from those elements. Of the tested samples 14% broiler meat and 50% spent hen samples found slightly higher level of “As” and 4-6 times “Cr” respectively than the MPC. In conclusion, the poultry farmers are suggested to buy poultry feeds from the reputed feed company and discourage to use loose feeds. Moreover, feed marketing channel particularly loose feed marketing should be monitored properly by the regulatory authority. Asian Australas. J. Food Saf. Secur. 2018, 2(1), 1-5

    Abstract: Four quail genotypes namely Japanese (J), White (W), Black (Bl) and Brown (Br) quail are being maintaining at Bangladesh Livestock Research Institute to develop meat type quail genotype. Studied fifth generation (G5) quails were hatched from 4th generation (G4) parents based on estimated breeding value for 5th week body weight. Standard management practices were followed during study period. Hatching eggs were collected from every single pen of the selected parent quails. A total of 1750 day-old chick comprising of J, W, Br and Bl were hatched in one batch. Collected data were analyzed in a CRD by General Linear Model (GLM) Univariate Procedure in SPSS Computer Program. Body weight of quails at 3rd, 4th, and 6th week of age were (p 〈 0.001) influenced by genotype. The 6th week body weight was 126.51, 133.19, 130.80 and 115.40g, respectively for J, W, Br and Bl genotypes. Body weight was higher (p 〈 0.001) in W and Br followed by Bl and J quail genotypes at different age. The hatchability rate was (p 〈 0.001) higher in J (58.38%) compared to other three genotypes of W (50.30%), Br (47.79%) and Bl (46.45%), respectively. Chick mortality during 0 to 5 week age did not varied (χ2 = 2.19; p 〉 0.05) among Bl (8.78%), J (6.66%), Br (6.31%) and W (5.36%) genotypes. Comparing the performances, W quail was superior for body weight and Bl quail for egg production. Bangladesh J. of Livestock Res. 21-25: 65-68, 2018

    Abstract: The study was conducted to identify the moringa species and to determine biomass production of Moringa sp. as a fodder crop. An experimental plot (2100 cm x 300 cm) was divided into three equal subplots (900 cm x 300 cm). Chemical fertilizer was applied (100-90-30, NPK), one-fifth of the total fertilizer after each harvest and the recommended amount of cow dung. Weeds were controlled in the experimental plot as they appeared. In a harvesting day, one unit of land containing 54 plants was cut into 3 different sections considering different cutting heights 1.5, 2 and 2.5 feet and cutting intervals after planting were 40, 50 and 60 days, respectively. The experimental design was 3 x 3 factorial design in this study. All plants were randomly selected from each harvested plot and separated manually into their different botanical fractions such as stem, twigs and leaves. The different fractions weight were recorded using an electric balance and freshly harvested biomass were sun dried. To identify the moringa plant taxonomically, the herbarium sheets were prepared with the samples from 6 different locations of Bangladesh. The herbarium sheets were matched with the control moringa herarium sheet at the library of Bangladesh National Herbarium Center, Mirpur Dhaka. As per result, the biomass yield of moringa at 40 days from sowing was significantly highest (p 〈 0.01) in 1.5 feet (278 kg/hec) to 2 feet (264 kg/hec) cutting from the ground compared to 2.5 feet (207 kg/hec). Similar trends were observed in 60 days. Interaction effect between cutting height and cutting interval was found significant. Moringa leaves contained crude protein (CP) 28.21% whereas stem and twigs contained 11.13% and 13.49% CP respectively in this study. Considering all the results it can be concluded that M. olifera may be cultivated as fodder crop and harvested with optimum cutting height of 1.5 feet at the age of 60 days. Bang. J. Livs. Res.

    Abstract: The study was conducted to know the existing turkey production system, supply chain mapping, and identifying the prospects and problems of turkey rearing in some selected areas of Bangladesh during October 2019 to December 2019. A total of 100 turkey raisers were surveyed following convenience method of sampling technique. The primary data were collected, analyzed accordingly and tabular presentation method was applied with the help of simple descriptive statistical measures e.g. frequency distributions, percentage, sum and means to illustrating the results. Profitability analysis was done on the basis of variable cost, fixed cost, return by using arithmetic means and percentages. The study revealed that 87 male and 13 female respondents were surveyed, of them cent percent found educated. About 56% turkey keeper’s main occupation was business, 27% service and 12% in farming while 88.57% involved with farming as secondary sources of income. Average landholding for homestead, cultivable and non-cultivable was 24.40, 129.71 and 29.47 decimal, respectively. About 59% farms started for commercial purpose, 32% for non-commercial purpose and 9% for both. About 60% respondents kept less than 50 turkeys and only 2% kept 501-1000 turkeys. Among the surveyed farms55% stopped their operation and 45% farms found running their business. Among the running farms cent percent were small-scale group. The average feed intake was 192.13 grams per day per bird at 20 weeks of age. Turkey laid on an average 139 eggs a year irrespective of variety and for hatching poults, the fertility and hatchability rate found between 65 to 100% and 50 to 90%, respectively. About 28% farmers experienced the deaths of turkey because of Cold, Pox, Ranikhet, Bird flu and unknown cases and 69.47% farmers took veterinary advice from Upazila Livestock Hospital and rest from other sources. Farmers to consumers were the most common and widely used marketing channel for egg, chick and adult turkey. The market intermediaries of turkey farm carried out different marketing functions e.g. buying and selling, pricing, transportation, sorting, distribution and market information. The average net return and benefit-cost ratio was BDT 127838.04 and 1.38, respectively for 50 turkeys per year. In the study, turkey rearing found some comparative benefit over chicken and ducks e.g. higher weight gain, forage eater, lower diseases rate and suitability for the country. The main problem of turkey rearing identified as market instability, lack of quality turkey feed, higher feed price, lack of proper marketing facility and training on turkey farming. In conclusion, the small-scale turkey farming could be a viable source of income for the rural people of Bangladesh after taking some remedial steps by the Government of Bangladesh for the aforesaid hindrances faced by the turkey farmers.

    Abstract: Aflatoxin (AF), a secondary metabolite of Aspergillus species, is carcinogenic and mutagenic for chicken. Chickens are highly sensitive to the adverse effect of AF and it is causing economic loss in poultry industry. The aim of the current study was to evaluate the efficacy of turmeric powder (TP) and garlic powder (GP) on broiler receiving diet containing exogenous AF. Randomly selected 14 days old cobb-500 broiler chicks (N=84) were equally divided into four treatments. Four isonitrogenous and isocaloric experimental diets were prepared viz; diet-A: 1.5 mg of AF; Diet-B: 1.5 mg of AF and 1g of TP; Diet-C: 1.5 mg of AF and 1 g of GP contained per kg feed and control diet had no AF, TP and GP. Each dietary treatment had 3 replications (having 7 birds in each) and respective feed was offered to the broilers according to the entire duration (35 days) of experiment. All experimental broilers were reared following same management practices. At 36 days of age all experimental broiler were slaughtered for examining the necroscopic changes in internal organs such as liver, kidney and spleen to estimate AF residues. Growth of the broiler chicken was monitored and feed conversion ratio (FCR) was calculated. The study demonstrated significant (P 〈 0.01) effect of turmeric and garlic powder on final body weight of birds and so also the FCR. Liver and kidney weight use showed significantly (P 〈 0.01) the highest in diet-A, followed by diet-B, diet-C and the control diet, respectively but, spleen weight did not differ significantly (p 〉 0.05) with the treatments. The residue of AF in different internal organs was also significantly (P 〈 0.05) different between the treatments; being higher in diet-A as compared to the rest of the dietary treatment groups. Evidently, the present study substantiated the potentiality of TP in broiler chicken to overcome the adverse effect of AF, a common mycotoxin. Bangladesh J. Agri. 2019-2021, 44-46: 89-95

    Abstract: The study aims to know the scenario of duckling production using rice husk incubator and socio-economic status of the farmers of Vatiapara village under Baniachang upazila of Habiganj District. A total of 140 number of households were interviewed among them 64.7% family had homestead land followed by 35.3% family had both homestead and cultivated land. All living houses were of tin made with 70% nuclear and 30% joint family. There about 9.1% illiterate and 39.4% people could sign only. The primary, secondary and higher secondary or upper educational levels were 25.7%, 18.2% and 7.6%, respectively. More than 76.5% family are engaged directly in duckling production whereas 23.5% family are involved in catching and cultivating fish. About 23.5% families were fully occupied in fisheries and 41.25% family in integrated agriculture as secondary occupation. On an average, their income was 10,676 Tk. Among the selected families 59% got training on duck rearing with hatchery management. Based on 70% hatchability, per family produced monthly more than 7000 number of ducklings from 10000 number of hatching eggs. The yearly turnover is calculated as to nine months hatching operation since the enterprise remained almost stop from the late November to mid-February. Hatching egg price was different due to seasonal variation and, on an average, it was 10.50 Tk. Overall 7088 number of ducklings were produced per household monthly, which valued about 177200 Tk. (25 Tk./duckling) and net profit was 66535 Tk./month. Thus, the community-based duckling production can be encouraged more among the families through providing an adequate technical knowledge, training and an improvement of marketing channel to increase socio-economic status of the farmers.

    Abstract: A total of 887 ducklings of BLRI-1 duck genotype and 352 ducklings of BLRI-2 duck genotype were studied to measure productive and reproductive performances under intensive management. Data were recorded on body weight, egg production, egg weight, fertility, embryonic mortality, hatchability, feed intake, age at sexual maturity, body weight at maturity and egg weight at maturity. The fertility rate in BLRI-1duck was significantly (p 〈 0.01) higher than that of BLRI-2 duck, while hatchability of BLRI-2 duck on fertile eggs were significantly (p 〈 0.05) better compared to BLRI-1 duck. The embryonic mortality was significantly (p 〈 0.01) higher in BLRI-2 duck than BLRI-1 duck. Duckling weight was influenced by egg weight (p 〈 0.05) but difference in duckling: egg ratio was not significant (p 〉 0.05). Hatching weight, 4th week and 12th week of age were significant (p 〈 0.05) influent while the body weight of ducks at 8th week did not differ significantly (p 〉 0.05) for BLRI-1 and BLRI-2 ducks, respectively. The least squares mean for age at sexual maturity were 158 days and 151.75 days, respectively for BLRI-1 and BLRI-2 ducks (p 〈 0.05). BLRI-1 duck started to lay eggs almost one week late compared to BLRI-2 duck. Duck weight at sexual maturity, egg weight at first lay and egg production did not have significant (p 〉 0.05) difference between genotypes. It may be concluded that BLRI-2 duck genotype is superior in terms of hatchability and age at sexual maturity to BLRI-1 duck genotype.
