There was significant (P<0.05) difference in biomass yield and chemical composition among different treatment groups. The maximum biomass yield (mt/ha) was observed in layer litter (16.67 a ± 0.89) followed by Broiler litter (10.05 bc ± 0.10), Biogas slurry (08.97 bc ± 0.99) and control group (06.65 c ± 0.90; respectively. It also showed that number of tiller/hill was significantly (P≤0.05) differed among the treatments and maximum observed in layer litter (19.50 a ± 1.05) than others. The DM% in all groups was mostly similar but DM yield was the highest (19.11± 0.44%)) in layer litter compared to others group. It may be suggested that layer litter may be used as organic sources of fertilizer as well as the soil health and fodder cultivation ...

The selection was done based on the concentration of dairy farming with fodder production as well as crop production. Descriptive statistics and one-way ANOVA were performed to analyze the gathered data, and the means were separated using DMRT mean separation test. It was found that 100% farmers cultivated fodder in their land. Results also showed that higher annual cost involved in Irri rice production than Jumboo and Napier production. However, non-significant differences existed among the market price of Irri, Jumboo and Napier production. Lower fertilizer used in fodder production than rice hence, lower fertilizer price (Tk) required for fodder than rice production. Annually fodder yield was 83.53 MT whereas rice yields only 6.94 MT per household....

One hundred twenty-eight birds were split into four dietary groups, with 32 birds in each group, comprising four replications with eight birds per replication. The experiment lasted 16 weeks and was conducted at the open houses shed in the Bangladesh Livestock Research Institute. The four dietary treatments were formulated using basal feed as follows: control (T 1), MOL 0.5% (T 2), MOL 1.0% (T 3) and MOL 1.5% (T 4). The quality, weight, length and width of eggs were not altered by the addition of MOL to the diet. Yolk colour and eggshell breaking strength were significantly higher in the additive groups. The results showed that dietary addition of MOL meal significantly reduced serum, total cholesterol and triglyceride content compared to the control. Feeding MOL at 1 and 1.5% increased W-3 fatty-acid levels by 1.35 and 1.46%, respectively. Overall, the results indicate that the addition of 1.5% MOL to layer feed could be an effective way to improve egg quality and fatty-acid profile and reduce cholesterol in egg yolk. HIGHLIGHTS Addition of Moringa oleifera leaves (MOL) in native laying hens basal diet improves egg quality. W-3 fatty-acid composition in yolk was enriched. Serum and yolk cholesterol levels in hens were significantly reduced (p < .05) in all additive groups.

Three (03) districts of Bangladesh viz. Bhola, Mymensingh, and Dinajpur were chosen from the coastal, river basin and semi-arid region, respectively. A triangulation method of survey was used to collect the data and the components of the triangle were buffalo farms, buffalo farmers and buffalo herdsmen. The investigation duration was twelve (12) months. The study revealed that the highest milk yield (5 L/h/d; p=0.010) was found in the river basin and semi-arid region. Lactation yield was also recorded double in the river basin and semi-arid districts compared to coastal districts (p=0.000). In the case of lactation length, the river basin buffaloes possessed 33 and 36% longer than coastal and semi-arid districts, respectively. All the chemical components were found significantly different (p≤0.050) but fat. Among different agro-climatic districts, about 92% of milk was traded in the coastal region after meeting the household's need but it was noted that the farmers from the semi-arid region kept more than 21% of milk for family consumption (p=0.000). The highest unit price (BDT 72/L) of milk was observed in the river basin district (p=0.011). In conclusion, the current situations of buffalo farming and milk marketing approaches in Bangladesh, varies considerably.

There were 44 chicks per treatment. Each treatment was replicated 4 times having 11 chicks in each block (replication). The dietary treatments were W0T100, W20 T80, W40 T60, W60 T40, W80 T20, and W100T0. All other ingredients used in the diet were similar and all diets were isocaloric and isonitrogenous that contained around 2930 Kcal ME/kg DM and 21.5% crude protein. Management condition was similar for all treatments. At 5 weeks of age, 2 broilers from each block were randomly selected and slaughtered to analyze the meat yield traits. There were no significant differences (p>0.05) in feed intake, water intake, initial weight, final weight, total gain, gain per day, feed conversion efficiency and mortality of broilers among dietary the treatments. The rela tionship between feed intake (x) and gain (y) was v...

It is a dual purpose crop, produced as both fodder and grain. The grain quality of triticale is very similar to wheat, even sometimes better than wheat due to its lysine and protein content. To determine biomass yield, nutritive quality, in sacco DM degradability and to identify the best lines suitable for fodder crops, an agronomic trial was conducted on the available germplasm of triticale at the Animal Research Station, Bangladesh Livestock Research Institute, Savar, Dhaka. Ten triticale lines including check/control were collected from Wheat Research Centre (WRC), Dinajpur and were cultivated in the fodder research plot of BLRI. The ten lines of triticale each replicating four times, were sown in 40 experimental plots, each of 5.0 x 2.4 m size. There were 12 rows in...

Therefore mass vaccination against HAV has not been recommended in endemic countries. Objective: To determine whether routine hepatitis A vaccination is indicated for all Bangladeshi children & also to know whether pre-vaccination screening is necessary. Materials & Methods: Serum samples from 254 children aged between 1-15 years were tested for antibody (IgM & IgG) against hepatitis A virus (HAV) to determine the seroprevalence of HAV antibody and do a cost-benefit analysis for decision making about vaccination against HAV among the children of Bangladesh. Results: Hepatitis A virus antibody was positive in 141 (55.5%) of 254 children. Age-specific sero-prevalence was 13 (23.2%) of 56 in 1-3 year, 64 (55.2%) of 116 in 3-5 year, 39 (70.9%) of 55 in 5-10 year & 25 (92.6%) of 27 in...

This study was conducted at the different Bathan areas of Shahjadpur Upazila under Sirajgonj district. The total of 30 repeat breeder cows was selected randomly to determine their reproductive hormonal profile before and after synchronization at the selected areas and repeat breeder cows were marked by ear tag and collected breeding history of each individual cow. All experimental RP were synchronized by the administration of GnRH (day-0), PGF2α (day-7) and Artificial Insemination (AI) with GnRH (day-9). Blood samples were collected before and after synchronization during standing heat period of estrous cycle of each cow. The total experiment was done and analyzed in the laboratory by using endocrine detection kits (Mono Lelac R USA). This present study revealed that the level of luteinizing hormone (LH), follicle stimulating hormone (FSH), progesterone (P4) were significantly differed between repeat breeder cows and synchronized repeat breeder cows. These findings clearly indicated that reproductive hormonal aberrations might be one of the major causes of repeat breeding in Baghabari milk shed areas.

Three Napier cultivars being conserved by Bangladesh Livestock Research Institute (BLRI), namely-BLRI-Napier 1, (BN-1), BLRI-Napier 3 (BN-3) and Merkeron (BN-5) were selected to cultivate in severe drought prone areas (called Barind) and non-drought area at Savar (Modhupur terrace). Stem cuttings were planted in rows apart from 70 cm and 35cm spacing between plants. Data of 6 consecutive harvests from a period of approximately one year were collected and analyzed statistically by "R" software. The results showed that cultivar and location had a significant (P < 0.001) effect on biomass yield, plant height and leaf-stem ratio (LSR), while number of tillers were significantly varied with locations. BN-3 yielded the highest biomass (33.32 t/ha/harvest) at nondrought location (42.98 t/ha/harvest). The highest plant height was obtained in BN-1 (171.2 cm) at non-drought location (174.6 cm). Number of tillers per hill ranged from 25.4 to 26.3 among cultivars (P > 0.05) and the highest tillers were found at non-drought location (28.1 no). The best LSR was estimated from BN-5 (0.86) at drought location (0.95). The proximate analysis showed that CP, ADF and NDF in whole plant were varied significantly (P < 0.001), being the highest contents in BN-1 (10.69%, 46.20% and 54.58%, respectively). On the other hand, DM and ash contents did not differ significantly (P > 0.05) among cultivars which ranged from 15.80% to 17.13% and 13.10% to 14.58%, respectively. The highest CP content in whole plant was obtained at non-drought location (11.89%), while the lowest ash (10.57%
