  • This experiment was conducted to determine RDP values of locally available feedstuffs that are commonly used in ruminant rations in Bangladesh. Four cattle were fistulated in the rumen for the in situ nylon bag studies. Seventeen different feedstuff sample (9 roughages and 8 concentrates) were evaluated in $4{\times}14cm$ nylon bags and incubated in the rumen for different periods of time (2, 6, 12, 24, 48 and 72 h). The variation in crude protein (CP) contents reflected on the average CP disappearance value throughout the rumen incubation. Soluble fraction (a), insoluble but degradable fraction (b) along with the rate of degradation also varied widely among the various feedstuffs. Under 2% of rumen outflow rate, the percentages of the calculated protein degradabilities of roughages were rice straw, 16.7; maize grass, 70.6; oat grass, 70.8; dhal grass, 71.1; sunhemp, 78.4; napier grass, 62.4; matikalai grass, 72.1; khesarikalai grass, 76.9 and daincha browse, 78.4, respectively. The results in the protein degradabilities (%) in 8% ruminal outflow rate of concentrates were wheat bran, 61.6; rice polish (red), 61.3; rice polish (auto), 30.9; mustard oil cake, 71.8; sesame oil cake, 74.2; coconut oil cake, 57.9; soybean meal, 49.2 and fish meal, 37.9, respectively.

  • The experiment was conducted to study the effect of supplementary urea molasses block lick with rice straw based diet on the performance of sheep. Six indigenous sheep of about two years of age with an average body weight of 12.88 kg, were selected for this experiment They grouped into two by stratified randomization, and the experiment was conducted for a period of 90 days. Sheep of group A was fed rice straw and group B was feed rice straw with urea molasses block lick, beside this both the groups received 66 g wheat bran and 167 g of Ipil-Ipil leaf meat. The study revealed that the average daily gain of live weight per sheep per day was 41 gm and 70 gm in group-A and group-B respectively. From the analysis of variance it was evident that live weight gain in sheep of group B, supplemented with urea molasses block lick was highly significant (p < 0.01). It was also estimated that group A required 8.12 kg DM to gain 1 kg live weight, whereas group B receiving urea molasses block lick required 5.30 kg DM to gain 1 kg live weight. Therefore, feeding rice straw with urea molasses block lick able to utilize more crop-residues efficiently.

  • Cultivation conditions for overproduction of lovastatins were investigated from the lovastatin producing strain N-03 which was obtained with NTG (N-methyl-N'-nitro-nitrosoguanidine) treatment from Aspergiliu ferrous ATCC 20542. Produced lactone and acid form of lovastatin were detected, and analyzed by HPLC method. In liquid culture, medium No. 2 containing soy protein produced higher amounts of the lovastatins than medium No. 1 (contained rapeseed oil). In solid culture, maximum production was obtained at 28$^{\circ}C$ for 15 days cultivation using cooked wheat bran. For the overproduction of lovastatin from this strain, solid culture method using plastic bag is more superior than liquid culture.

  • Sclerotinia sclerotiorum fungus has three endoxylanases induced by wheat bran. In the first part, a partial xylanase sequence gene (90 bp) was isolated by PCR corresponding to catalytic domains (${\beta}5$ and ${\beta}6$ strands of this protein). The high homology of this sequence with xylanase of Botryotinia fuckeliana has permitted in the second part to amplify the XYN1 gene. Sequence analysis of DNA and cDNA revealed an ORF of 746 bp interrupted by a 65 bp intron, thus encoding a predicted protein of 226 amino acids. The mature enzyme (20.06 kDa), is coded by 188 amino acid (pI 9.26). XYN1 belongs to G/11 glycosyl hydrolases family with a conserved catalytic domain containing $E_{86}$ and $E_{178}$ residues. Bioinformatics analysis revealed that there was no Asn-X-Ser/Thr motif required for N-linked glycosylation in the deduced sequence however, five O-glycosylation sites could intervene in the different folding of xylanses isoforms and in their secretary pathway.

  • In order to at day evaluate effect of dietary 2.0 % brown seaweed(Undaria pinnatifida) with bean extract on performance and nutrients utilization during acute phase response, one day-old broiler chicks were fed basal diet and diets substituted with 2.0 % brown seaweed and 2.0 % brown seaweed with bean extract instead of wheat bran in basal diet for 4weeks. Dietary 2.0 % brown seaweed with bean extract enhanced dietary ME value and protein accumulation due to the increased NB and decreased UAN excretion. increased feed intake during acute phase response and had the highest body weight among birds fed experimental diets. The resulted indicated that dietary 2.0 % brown seaweed with bean extract improved performance of broiler chicks due to the increased protein accumulation during acute phase response.

  • Artificial diet (AD) has shown with different advantages over mulberry leaves (ML). Various types of such feed for silkworm have been developed and proposed. The aims of this study were possibility rearing whole instar of silkworm on AD and to find some economic formulation for rearing silkworm, compare to that ML. Eleven ADs (D$_1$ to D$_{11}$) were prepared with different percentage of mulberry leaf powder, and other ingredients such as soybean meal, cellulose, potato starch, agar, wheat flour, rice bran, etc. Five formulated diets (D$_1$ D$_2$, D$_{5}$, D$_{10}$ and D$_{11}$) appeared to have similar response to that ML (D$_{m}$). There were no significant differences for duration period between ADs, all of which recorded with higher duration than mulberry leaves. Compared to other died used in the present study D$_1$ and D$_{10}$ showed better growth development and survival rate. Larvae fed D$_1$, D$_2$, D$_{5}$, D$_{10}$ and D$_{11}$ grew faster and produced heavier and more useful cocoons.coons.coons.coons.

  • A fungus, Penicillium sp. PS-113, isolated from soil showed the high phosphate-solubilizing activity in patato dextrose broth-rock phosphate to produce free phosphates to the culture broth with the concentrations of 585 ppm against rock phosphate. In this medium, the optimum temperature and initial pH to solubilize rock phosphate were 30$^{\circ}C$ and pH 7.5, respectively. In order to make the mass production of the conidia from this fungus, we cultured in on various solid-based media like barley, corn, wheat, rice, rice bran, and compost. As a result, the fungus highly produced conidia ranging from 2.1 to $5.1{\times}10_9$ conidia/g${\cdot}$media on these solid media except compost-based medium, which was 0 times less than others. Effects of inoculation of the phosphate solubilizing fungus as a biofertilizer were studied in perlite-based pot cropped with Zea mays Suwon 19. Inoculation of Penicillium sp. PS-113 increased in plant height (1.4 times), plant weight (5.2~8.1 times) and root length (1.1~1.2 times) at 60-day cultivation, compared to Hogland solution either without $NH_4H_2PO_4$ or displace $NH_4H_2PO_4$ to powdered rock phosphate, a phosphorus source for plant growth.

  • A selected fungal strain, for production of the raw-starchdigesting enzyme by solid-state fermentation, was improved by two repeated sequential exposures to ${\gamma}$-irradiation of $Co^{60}$, ultraviolet, and four repeated treatments with Nmethyl-N'-nitrosoguanidine. The mutant strain Aspergillus sp. XN15 was chosen after a rigorous screening process, with its production of the raw-starch-digesting enzyme being twice that of usual wild varieties cultured under preoptimized conditions and in an unsupplemented medium. After 17 successive subculturings, the enzyme production of the mutant was stable. Optimal conditions for the production of the enzyme by solid-state fermentation, using wheat bran as the substrate, were accomplished for the mutant Aspergillus sp. XN15. With the optimal fermentation conditions, and a solid medium supplemented with nitrogen sources of 1% urea and 1% $NH_4NO_3$, 2.5 mM $CoSO_4$, 0.05% (v/w) Tween 80, and 1% glucose, the mutant Aspergillus sp. XN15 produced the raw-starch-digesting enzyme in quantities 19.4 times greater than a typical wild variety. Finally, XN15, through simultaneous saccharification and fermentation of a raw rice corn starch slurry, produced a high level of ethanol with $Y_{p/s}$ of 0.47 g/g.

  • The Screening of fungi producing naringinase was done. A strain of Aspergillus midulans showed the highest naringinase activity among 447 strains those were isolated from soil, spoiled citrus friuts and stock cultures. The cultural Conditions of Asp. nidulans for production of naringinase were studied. A strain of Asp. nidulans showed higher activity when it was cultivated at 30$^{\circ}C$ for 3 days on wheat bran media supplemented with 2.0% naringin, 0.2% (NH$_4$)$_2$ SO$_4$ and 0.2% CaCO$_3$.
