This experiment was conducted to evaluate the quality of Indrani vough prepared in the laboratory and collected from Dinajpur district. Four types of Indrani vough samples were used in this experiment. Laboratory made Indrani vough was assigned as A sample. B, C and D samples were collected from Shananda sweet meat , Pabna sweet meat and Jalozogh sweet meat shop respectively. All the samples were tested for organoleptic, chemical and microbiological parameters. Among organoleptic parameters such as body and texture, color and appearance, and taste score of four types of samples differed insignificantly, but quality of samples differed significantly for flavour score (p<0.01). Chemical and microbiological analyses indicated that significant differences among four types of samples were found for protein, fat, carbohydrate, ash, acidity and Total Viable Count (p<0.01), except dry matter and moisture contents. From the present study it was concluded that Sananda sweet meat shops Indrani vough was superior to others. But laboratory made Indrani vough was the best in relation to microbiological status.

The study was performed for investigating the dietary effect of different levels of mushroom (Agaricus bisporus) powder on the performance of broiler. Four experimental rations designated as T0, T1, T2 and T3 having 0g, 5g, 8g and 10g dried mushroom powder/kg of feed was fed to 120 broiler chicks (Cobb 500), randomly distributed into 8 replicates, so as to have 2 replicates per treatment containing 15 chicks in each. The experiment was carried out for 30 days. Average weight gain, feed consumption, feed efficiency, dressing yield and survivability were used as criteria of response to feeding mushroom powder. Organs weight including heart, liver and gizzard were also recorded. The mean body weight per broiler was 1292.24, 1501.66, 1445.19 and 1434.97g in 30 days for the treatment of groups T0, T1, T2, and T3 respectively (P<0.01). The average feed consumption per broiler was 2374.77, 2273.55, 2283.86 and 2276.3g (P<0.01) in 30 days for the groups of T0, T1, T2, and T3 respectively. The average feed efficiency (feed/kg body weight gain) was 1.84, 1.52, 1.58 and 1.59 (P<0.01) in 30 days for group T0, T1, T2, and T3 respectively. The mean dressing yield was 57.16%, 60.63%, 58.89% and 61.42% (P<0.01) for the groups of T0, T1, T2, and T3 respectively. The average weight of abdominal fat 2.69%, 1.55%, 1.74% and 1.65% (P<0.01) and heart was 8.5, 10.25, 8.5 and 7.6g (P<0.05). The average weight of liver was 43.1, 43.5, 46 and 43.5g (P>0.05) for the groups of T0, T1, T2, and T3 respectively. The mean gizzard weight was 35.25, 35, 34.5 and 35.75g (P>0.05) for the groups of T0, T1, T2, and T3 respectively. Survivability was 100%, for all the groups of T0, T1, T2, and T3 respectively. It may be concluded that the use of mushroom as feed additive at a level of 5g enhances the overall performance of broiler chicks.

This study was conducted to investigate the changes in morphology, biomass yield, chemical composition and production cost of Hydroponic Wheat Fodder (HWF) with the advancement of growing days. The HWF was cultivated at low cost sprouting house at the Bangladesh Agricultural University (BAU) Dairy Farm, Mymensingh, Bangladesh. Firstly, wheat grains were collected, washed and then soaked in tap water for 12 h. Thereafter, grains were wrapped with a gunny bag for 24 h for germination. Then, grains were spread out in trays and irrigated using tap water up to 8th day morning. Biomass yield, morphological, nutritional parameters and cost of production were determined daily from each of the eight batches (day, 0 to 8) in the sprouting house. An increasing trend was seen in biomass yield, plant height, root length and root number of HWF with the days of advancement and found highest on 8th day (p=0.000). Biomass yield was increased 6 times during this 8 days cycle. On the contrary, a decreasing trend was observed in cost of production (0-5th day) and found lowest (BDT. 5.00) value in day 6th -8th (p < 0.001). A strong positive (r=0.891-0.989) correlation exists between biomass yield and morphological features (p < 0.001). Whereas, cost of production negatively (r=-0.857--0.946) correlated with biomass yield and morphological parameters (p < 0.001). The dry matter content of HWF reduced (p <0.001) gradually from day 0 to 8. The crude protein, ether extracts and minerals (calcium, phosphorus and magnesium) content of HWF increased positively from day 0 to 8 but nitrogen-free-extracts and organic matter declined (p < 0.001) gradually. However, morphology, biomass yield, chemical composition and production cost of fodder were similar between the days of 7 to 8. Finally, farmers might grow HWF up to 7-8 days as a new source of livestock feed.

An experiment was conducted to study the effect of micronutrients supplementation on body weight of cows, birth weight of calf, colostrums composition, milk yield and milk composition. Six animals were divided in to two groups viz. control and supplemented group. Control group was provided conventional diet and supplemented group was supplied conventional diet plus vitamin-mineral mixture (1g vitamix powder/1kg concentrate feed) respectively for two months before calving. In supplemented group the average daily gain of the cows was (49.17 g/d) higher (P<0.01) and the calves were 2 kg heavier in supplemented group compared to control group. Fat content and protein content of colostrum in supplemented group were also significantly higher (P<0.01 and 0.05). The milk yield, fat and protein values of milk were increased non-significantly by 1.03 kg/d/h, 2.8 g/kg and 0.3 g/kg respectively. Ca content of milk was more or less similar in both cases.

An experiment was conducted to investigate the effect of supplementing of exogenous phytase enzyme on productivity of commercial broilers. Four strains of commercial broiler such as Fast feather, Arbor acres, Cobb-500 and Hubbard classic each having 78 numbers were reared for a period of 5 weeks. A total number of 312 day old broiler chicks were distributed into two dietary treatments i.e. basal diet (Control-T0) and basal diet supplemented with phytase enzyme 1g/kg feed (supplemented-T1). The results indicated that broilers fed on diets supplemented with phytase have gained more body weight when compared with control group (P<0.05). The first and second highest body weights were recorded for the strains Cobb-500 and First feather broilers, respectively, which feed on diet containing phytase. Feed consumption varied significantly between the broilers on different dietary regimes. Significant differences (P<0.01) were found in feed conversion ratios among the birds fed on diet with phytase enzyme. The lowest feed conversion ratio was in Cobb-500 fed on phytase diet where as the highest was in Fast Feather provided with only basal diet during the 5th week of age. Average feed conversion ratios were 1.73 and 1.86 for the supplemented and control group respectively. Use of phytase as feed additive in the diet resulted in high profitability/ broiler. Net profit per live broiler was the also higher in treatment group compared with control groups of birds. The highest net profit per live broiler was observed in Arbor Across strains fed on phytase diet. The result of the present study suggests that the addition of dietary phytase enzyme in the diet of broiler may increase the production performance and reduce the cost of production.Bang. J. Anim.
