An experiment was conducted to know the possibility of using <em>Saccharomyces cerevisiae </em>derived SCP in broiler diet. A total of 96 male Ross-308 day old chicks were assigned to four diet comprising control (0% replacement), 25% replacement, 50% replacement and 100% replacement of protein concentrate with autolyzed <em>S. cerevisiae</em>. Each group had 6 replicates of 4 chicks in each. Body weight, body weight gain, daily weight gain, feed intake and feed conversion ratio were not affected (<em>P</em>&gt;0.05) in case of 25% and 50% replacements. However, 100% replacement had resulted numerically negative effect as compared to control group. Dressing percentage and other carcass characteristics were not affected (<em>P</em>&gt;0.05) in the replacement groups. The results of this study indicated that autolyzed <em>S. cerevisiae</em> might be used to replace protein concentrate at 25% to 50% level in broiler diet without affecting growth and carcass quality.</p> <p><strong><em>Bang.

For this study, sixteen indigenous bulls <em>(Bos indicus</em>), around two years age (132.5±20.5 kg of LW), were divided into four groups having four animals in each treatment group. The animals were supplied with four different sources of water viz. Deep Tube Well Water (DTW =T<sub>1</sub>), Supply Water from reserve tank (SW = T<sub>2</sub>), Pond water (PW = T<sub>3</sub>) and River water (RW = T<sub>4</sub>). All the animals were fed German Grass (<em>Echinochloa polystachya </em>L.) and concentrate mixture. All the animals were free access to water. Live weight was recorded initially and week interval till end of the feeding trial (12 weeks). The results revealed that animal belonging T<sub>1 </sub>treatment group showed best growth performance was better in comparison to other treatment groups. Dry matter intake (DMI) was highest for T<sub>1</sub> group (3.08 ± 0.08 kg/d) and lowest for T<sub>4</sub> group (2.81 ± 0.18 kg/d). The digestible nitrogen free extract (DNFE) and total digestible nutrient (TDN) were higher (<em>P</em>&lt;0.05)in T<sub>1</sub> group compared to other groups. The highest daily body weight gain (336.49±59.40 g/d) was observed in T<sub>1</sub> group. Based on the results, it is concluded that deep tube well water (T<sub>1</sub>) is suitable for cattle for its quality which showed positive impact on intake and growth of animals. Further study might be needed to compare the cost involvement for different sources of water and economy of growth of animals.</p> <p><strong><em>Bang. J. Anim.

A total of 96 blood samples were collected from adult sheep of Barind (24), Jamuna River Basin (24), Coastal (24), Garole(10) and available Chotanagpuri (10) sheep. Chotanagpuri sheep was used as an outgroup population. DNA was extracted from blood samples using QIAGEN DNA Mini extraction kit and was quantified using a nanodrop. FAO recommended 13 labeled microsatellite markers were used for polymerase chain reaction (PCR). PCR product was confirmed by 2% agarose gel electrophoresis and visualized by staining with ethidium bromide.The exact allele sizes in each primer were determined by GeneMaker V1.85 demo. Microsatellite tool kit and Dispan software package were used for calculation of allele frequency, number of alleles per locus, observed and expected heterozygosity and genetic distances (D<sub>A</sub>). The Dispan software was used to calculate inter-individual genetic distances. These distance values were used to construct an UPGMA tree. Results showed that average number of polymorphic alleles per locus varied from4 in HUJ616 to 12 in MAF70. Observed heterozygosity was also varied from 0.54±0.04 in Coastal to 0.63±0.03 in Barind sheep population. Genetic distance between Jamuna river basin and Barind was lowest (0.01) and between Garole and Costal was highest (0.17). Garoleand Chotonagpuri sheep has higher genetic distance from other three sheep populations. Phylogenetic dendogram showed that sheep of Jamuna river basin and barind were belonged to same genetic group. Whereas, coastal, garole and Nagpur sheeps were shown higher genetic distances from Jamuna river basin and coastal sheep. Considering findings of this study it may be concluded that the Barind and Jamuna river basin sheep belongs to a similar genetic group while, Garole and Coastal sheep are belonging to two distinct genetic groups.</p> <p><strong><em>Bang.

The experiment was conducted to find out appropriate level and duration of supplementation to the pregnant doe. The data of the experiment were analyzed applying Completely Randomized Design (CRD) with factorial arrangements with three replications. First factor used in the experiment was the duration of concentrate feeding (15 days, 30 days, 45 days and 60 days) and second was amount of concentrate supplemented (2.00%, 1.75%, 1.50% and 1.25% of their body weight). Birth weight, weaning weight, milk yield and kid mortality in different groups were recorded. Birth weight and weaning weight were found higher in 60 days supplemented group i.e. 2.3±0.23 kg and 10.94±0.41 kg, respectively. Both birth weight and weaning weight were also found higher with 2 percent concentrate feeding group than others i.e. 2.1±0.23 kg and 9.64±0.42 kg, respectively. Milk yield recorded for fourth week shows that higher milk yields were found in 2 percent concentrate supplemented group with 60 days time period. The result showed that by increasing the level of concentrate during late gestation period of does increased the birth weight, weaning weight of kids and increased milk yield of does. So the higher level of concentrate supplementation is required during 45 to 60 days of late gestation in does.</p> <p><strong><em>Bang. J. Anim.

For determining the competitive land use efficiency of Mornga feed (M<sub>f</sub>) production, the Moringa fodder was cultivated in Gaibandha district at ABJF-AEZ with four replications. The annual dry matter (DM) yield of Moringa at on-farm condition was the height (26.67 ton/ha) and it was varied significantly (<em>P</em>&lt;0.05) with on-station condition. Comparing the Moringa fodder with available cash crop, the cost of production of Moringa was higher than that of other two cropping system like Boro-fellow-Jute (BFJ) and Boro-Fellow-Matikalai (BFM) but the gross return of Moringa cultivation was Tk.186.3 thousand, it was about five times higher income than existing cash crop. For determining the impacts of M<sub>f </sub>&nbsp;on milk production and their quality, twelve local cows of third or fourth parity after 1 to 2 weeks of calving in Gaibandha Sadar Upazila were selected and divided into three dietary groups having four animals in each considering their live weight and ante-diet daily milk yield. During 50 days feeding period all experimental cows were fed freshly threshed rice straw and keeping randomly a group under on farm practice that received supplementation of conventionally mixed concentrates (CMC), the other two groups of cows were either received a commercial cattle feed available at the market or M<sub>f</sub> replacing conventional concentrate supplements. M<sub>f</sub> produced significant amount of milk (1.64 kg/day) and meat (441.3 g/day) followed by commercial cattle feed (1.1 kg/day and 128.2 g/day) and CMC (0.73 kg/day and 48.4 g/day), respectively. It was also indicated that M<sub>f</sub> is better than market feed for the increase of milk yield and live weight gain.

The cows were randomly allocated to three dietary treatment groups, i.e., T<sub>0</sub>, T<sub>1</sub> and T<sub>2</sub>. The cows of T<sub>0</sub> group received farmers’ diet (63% of dry matter intake of cows according to ARC, 1995) without the supplementation and &nbsp;served as control.

The total live weight gain before calving of RC cows were observed significantly (<em>P</em> &lt;0.05) higher in T<sub>2</sub> and T<sub>1</sub> groups than T<sub>0</sub> group.
