Ruhul Amin Open Journal Systems <p>Official journal of the Bangladesh Animal Husbandry Association, Bangladesh Agricultural University, Mymensingh</p> Effects of moisture content on the quality of vermicompost produced from cattle manure 2022-06-24T14:09:27+00:00 MS Hossen MRI Khan MAK Azad MA Hashem MKJ Bhuiyan MM Rahman <p>This research aimed to evaluate the quality of vermicompost produced from cattle manure at different levels of moisture content. For this purpose, cattle manure containing different moisture content such as 60% moisture (T<sub>1</sub>), 70% moisture (T<sub>2</sub>) and 80% moisture (T<sub>3</sub>) treatments were adopted with 3 replications. A total of 9 vermicomposting pits were filled with 25 kg of cattle manure, each having the same amount of red worms. Parameters studied were dry matter (DM), crude fibre (CF), crude protein (CP), ether extract (EE), ash and pH. Results showed that 63% DM was increased in T2 and this value was significantly higher than T<sub>1</sub> and T<sub>3</sub> (p&gt; 0.05). The rate of CF degradation was 46, 78 and 72% in T<sub>1</sub>, T2 and T<sub>3</sub>, respectively. The CF degradation was also significantly higher in T<sub>2</sub> compared to the other two treatments (p&gt; 0.05). In the case of CP, a slightly higher CP was found in T<sub>2</sub> followed by T<sub>1</sub> and a little bit lower in T<sub>3 </sub>after 60 days of vermicomposting period. The EE content was slightly higher in all 3 treatments after 60 days of vermicomposting, but this difference was not significantly different among the treatments. The ash content was slightly higher in all 3 treatments after 60 days of vermicomposting, but this difference was also not significantly varied. The pH was significantly differed with the 3 treatments after 60 days of vermicomposting. From the above results, it was revealed that T<sub>2</sub> would be the suitable level of moisture for CF degradation and increased CP content in the final vermicompost. Therefore, it might be concluded that cattle manure containing 70% initial moisture would be a good option for vermicomposting.</p> <p><strong>Bangladesh Journal of Animal Science. 2022. 51 (2): 40-46</strong></p> 2022-06-30T00:00:00+00:00 Copyright (c) 2022 Herbage mass of Teosinte (Euchlaena mexicana) grown as mono and mixed with legumes 2022-06-24T14:28:51+00:00 B Khanal NR Devkota MR Tiwari NA Gorkhali <p>The popular summer cereal fodder is Teosinte (<em>Euchlaena mexicana</em>) which has low productivity and chemical constituents. The quality and quantity of teosinte fodder can be enhanced by adjusting cultivation practices including use of appropriate sowing dates and by following an appropriate mixed cropping cultivation with legumes. This study was conducted to identify the fodder quantity and quality under a commonly practiced mixed cultivation of legumes with teosinte with varied sowing dates. Three combination of fodder; teosinte, teosinte+cowpea and tesosinte+rice bean was arranged in four sowing dates in Split Plot Design, replicated five times. Sowing dates were arranged as main plot while combination of fodder species was arranged as sub plot. Growth parameters of teosinte (tiller numbers/m2, plant height), green herbage mass, dry herbage mass, crude protein (CP), acid detergent fiber (ADF) and neutral detergent fiber (NDF) were determined. The results showed significantly highest (p&lt;0.05) cumulative green and dry herbage mass was obtained from teosinte+cowpea, if sown in 18<sup>th</sup> April followed by 28th April for the same combination of treatments. Significantly the highest (p&lt;0.001) average value of CP was obtained from teosinte+cowpea whereas the highest (p&lt;0.001) average value of NDF and ADF were obtained from teosinte mono crop. The effect of date of sowing and treatments interaction/combination on average value of CP, NDF and ADF were statistically similar (p&gt;0.05). The result of this experiment indicated that teosinte sown with cowpea in 18<sup>th</sup> April might be the best combination to produce high herbage mass as well as better quality of fodder.</p> <p><strong>Bangladesh Journal of Animal Science. 2022. 51 (2): 47-54</strong></p> 2022-06-30T00:00:00+00:00 Copyright (c) 2022 Influence of dietary organic acid, probiotic and antioxidant on the growth performance and nutrient digestibility in growing rabbit 2022-06-24T14:37:34+00:00 R Chowdhury MA Rahman M Al Mamun <p>This study was conducted to compare the effects of different feed additives namely, organic acid (citric acid), probiotic (navio plus), and antioxidant (Bio-Sel-E) on the growth performance and nutrient digestibility in growing rabbit to convey a clear message on the use of one specific additive in rabbit diet. Thirty-two crossbred New Zealand White growing rabbit (four to five weeks of age) were randomly assigned to four different groups and reared for a period of fifty six days. Rabbit were fed on green grass (<em>Hymenachne pseudointerrupta</em>) and concentrate mixture (2703 Kcal ME/kg, 16.91 % CP). Additives were added at the top of the concentrate mixture, except for the control group. Compared with the control group, rabbit fed different additives showed 9–13% higher growth rate and 7–11% greater growth velocity; and probiotic supplemented group showed the best result (<em>P</em>&lt;0.05) in terms of FCR value. Carcass weight (%) increased significantly in probiotic supplemented group, but numerically in organic acid and antioxidant supplemented groups compared with control group. Abdominal fat (%) was significantly decreased in organic acid, probiotic and antioxidant supplemented groups compared with control, however, lowest value (%) was recorded in probiotic supplemented group. Probiotic showed significant effect on pH decreasing trend in ingesta sample up to small intestine. Crude protein digestibility co-efficient (%) value was significantly higher in probiotic supplemented group, but numerically in organic acid and antioxidant supplemented groups compared with control group. Overall results indicated that, among the three different additives: organic acid, probiotic and antioxidant, probiotic may be considered as the best one for the better performance and nutrient digestibility in growing rabbit.</p> <p><em>Bangladesh Journal of Animal Science</em>,&nbsp;51 (2): 55-61.</p> 2022-06-30T00:00:00+00:00 Copyright (c) 2022 Effect of Napier silage on milk production of Holstein Friesian Crossbred Cow 2022-06-24T14:47:38+00:00 MAA Habib MA Akbar ZH Khandaker <p>This work aspired to evaluate the quality of different types of silage on milk production made from whole napier grass, napier stem, and napier leaf. Napier grass <em>(Pennisetum Purpureum) </em>was harvested at 70 days of age and made into three types of silage in three different silo pits under proper anaerobic conditions for 45 days. A feeding program of 60 days duration was designed on nine (9) lactating (110-140 days after calving) Holstein Friesian crossbred dairy cows of 2<sup>nd </sup>parity (age 6-7 years, live weight 500±5 kg). The cows were divided into 3 groups and assigned to 3 dietary treatments, basal ingredients with whole napier grass silage (T<sub>1</sub>), basal ingredients with chopped napier leaf silage (T<sub>2</sub>), and basal ingredients with napier stem silage (T<sub>3</sub>). After ensiling, it was found that napier stem silage possesses the highest pH value indicating low-quality silage whereas napier leaf silage possesses the lowest pH value. The pH value of whole napier grass silage was slightly higher than that of napier leaf silage. Concentrations of CP and NH<sub>3</sub>-N were highest in napier leaf silage and lowest in napier stem silage. The CP value was almost similar in whole napier grass silage and napier leaf silage but the NH<sub>3</sub>-N value of whole napier grass silage was lower than that of napier leaf silage. Among the three groups, the cows of napier leaf silage group gave significantly (P&lt;0.05) higher milk yield than the cows of whole napier grass and napier stem silage group. On the other hand, the cows of napier stem silage group gave significantly (P&lt;0.05) lower milk yield than the cows of whole napier grass and napier leaf silage group. It can be concluded that napier leaf and whole napier grass silage are comparatively better than napier stem silage in respect to milk production of dairy cows.</p> <p><em>Bangladesh Journal of Animal Science</em>,&nbsp;51 (2): 62-67.</p> 2022-06-30T00:00:00+00:00 Copyright (c) 2022 Changes in morphology, nutrient content and production costs of hydroponic wheat as fodder 2022-06-24T15:01:04+00:00 MS Bari MN Islam MM Islam MR Habib MAH Sarker MM Sharmin MH Rashid MA Islam <p>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 8<sup>th</sup> 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.&nbsp; 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 8<sup>th</sup> 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 (0-5<sup>th</sup> day) and found lowest (BDT. 5.00) value in day 6<sup>th</sup> -8<sup>th</sup> (p &lt; 0.001). A strong positive (r=0.891-0.989) correlation exists between biomass yield and morphological features (p &lt; 0.001). Whereas, cost of production negatively (r=-0.857--0.946) correlated with biomass yield and morphological parameters (p &lt; 0.001). The dry matter content of HWF reduced (p &lt;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 &lt; 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.</p> <p><em>Bangladesh Journal of Animal Science</em>,&nbsp;51 (2): 68-80.</p> 2022-06-30T00:00:00+00:00 Copyright (c) 2022 Sensorial, chemical and microbial quality of spongy rosogolla 2022-06-24T15:10:07+00:00 MS Hossain MMH Khandakar MN Islam MA Islam <p>The goal of this investigation was to compare the physical, chemical and microbial qualities of laboratory made and market spongy <em>rosogolla</em>. Two types of spongy <em>rosogolla</em> were made in laboratory from the cow and buffalo milk chhana to reveal the quality in regards of the species and three types of market spongy <em>rosogolla</em> were collected from three different shops. With regard to the physical attributes, laboratory made spongy <em>rosogolla</em> were found better than the market spongy <em>rosogolla</em> and cow milk spongy <em>rosogolla</em> was the best. In chemical aspects, laboratory made spongy <em>rosogolla</em> had greater pH, fat, protein, and ash content, whereas, market spongy <em>rosogolla</em> showed higher acidity and carbohydrate content. The moisture content of cow milk spongy <em>rosogolla</em> was highest. The mineral contents (Ca, P, and Mg) were also differed significantly (p&lt;0.01) among the samples except for Na content. Highest Ca, P and Mg contents were found in market spongy <em>rosogolla</em>. The total viable count (TVC) was significantly (p&lt;0.01) lower in laboratory made spongy <em>rosogolla</em>. However, the <em>Escherichia coli</em> count was found similar (p&gt;0.05) in both cow and buffalo milk spongy <em>rosogolla</em> but lower (p&gt;0.05) than other market spongy <em>rosogolla</em> samples. Considering all the findings, it may be concluded that the quality of market spongy <em>rosogolla</em> needs improvement and responsible authorities might take necessary initiatives for monitoring.</p> <p><em>Bangladesh Journal of Animal Science</em>,&nbsp;51 (2): 81-84.</p> 2022-06-30T00:00:00+00:00 Copyright (c) 2022 Erratum for Volume 51 Issue1 March 2022 2022-06-24T15:26:05+00:00 J Begum <p>In “<strong>Chhana binders effects on the quality of Rosogolla</strong>” by Begum <em>et al</em>.
