Bangladesh Journal of Animal Science 2020-09-20T13:43:03+00:00 Professor Dr. Md. Ruhul Amin Open Journal Systems <p>Official journal of the Bangladesh Animal Husbandry Association, Bangladesh Agricultural University, Mymensingh</p> Evaluation of sperm motility and velocity of different genetic groups of bucks using Computer-Assisted Sperm Analyzer 2020-09-20T13:43:03+00:00 MR Islam MKU Talukder MS Rahman SS Husain <p>Semen quality assessment is a prime prerequisite for any breeding programme. Computer-Assisted Sperm Analyzer (CASA) can measure the semen quality very accurately and sharply. The research was conducted at American Dairy Limited (ADL) at Vangnahati, Sreepur, Gazipur. A total of 120 ejaculates were collected from three genetic groups of bucks namely Black Bengal (BB), Boer and Jamunapari (JP) with a view to characterize and compare the semen motility and velocity parameters using Computer- Assisted Sperm Analyser. Significantly (p&lt;0.05) higher ejaculate volume was found in Boer buck (1.73±0.16 ml) with the lower in BB buck (0.98±0.14), respectively. But significantly (p&lt;0.05) higher total, forward progressive and fast motility was found in BB (55.47±3.17, 47.23±2.74 and 37.62±2.40%) and lower in JP (40.67±3.37, 30.97±2.91 and 21.81±2.55%), respectively. Significantly (p&lt;0.01) fastest straight line and average path distance was observed in Boer bucks (12.29±1.63 and 15.89±1.95 μm) than Black Bengal and Jamunapari bucks (4.38±1.19 and 7.26±1.57; and 3.14±1.27 and 8.42±1.95 μm), respectively. The distance curved line (DCL) and distance straight line (DSL) was significantly (p&lt;0.05) higher in Boer (29.13±4.87, 12.29±1.63 and 15.89±1.95 _m/sec) and lower in BB (22.07±4.36 and 7.26±1.57 _m/sec), respectively. In case of curvilinear velocity, straight line velocity and average path velocity value was significantly (p&lt;0.01) higher in Boer (127.08±13.88, 50.01±7.68 and 68.13±7.25 _m/sec) with lower in JP (62.01±12.77, 15.75±7.35 and 22.39±9.42) where as linearity and straightness was higher in Boer and lower in BB (p&gt;0.05), respectively. The scrotal circumference had positive correlations with semen volume and curvilinear velocity for all the genotypes. It was concluded that semen of Boer bucks found consistently better than other two genetic groups of bucks. Further, competitive studies with large sample may be performed to evaluate the breed specific differences in available goat breeds. I think this study also disclosed the some rare parameters of semen quality by using Computer-Assisted Sperm Analyzer which was impossible in manually. These results of the present study could be an authentic guideline in future performance tests of different genetic groups of bucks.</p> <p><em><strong>Bang. J. Anim.

Chopped maize stovers were preserved in plastic containers under airtight condition at room temperature based on the treatments as T<sub>0</sub> (0% CLE), T<sub>1</sub> (20% CLE), T<sub>2</sub> (40% CLE) and T<sub>3</sub> (60% CLE) to investigate physical quality, chemical composition, in vitro organic matter digestibility (IVOMD) and metabolizable energy (ME) content at 0, 30, 60 and 90 days. The CP and Ash were increased (P&lt;0.01) and DM, OM and CF were decreased (P&lt;0.01) in all the treatments (T<sub>1</sub>, T<sub>2</sub> and T<sub>3</sub>) compared to controlled T<sub>0</sub>. The OM content was decreased numerically with the ensiling time. The EE content was not significant (P&gt;0.01) with the treatments and ensiling time. The OMD and ME content were increased (P&lt;0.01) with the ensiling time from 0 to 90 days. The physical quality (color, smell, and hardness) of maize stover were improved by CLE added treatments (T<sub>1</sub>, T<sub>2</sub> and T<sub>3</sub>) after ensiling but 60% CLE treatment had some pungent smell in 90 days and less OMD and ME value was observed than that of T<sub>2</sub>. Considering all the physical and chemical properties, among all the treatments, 40% and 60% CLE are acceptable for preparing wastelage. By comparing physical quality, nutritive value and chemical composition between 40% and 60% CLE treatments, the 60% CLE was better. Thus wastelage prepared from 40% CLE, 55% maize stover along with 5% molasses will be a potential source of ruminant feed as well as reduce the environment pollution by utilizing CLE.</p> <p><strong><em>Bang.

Two hundred fifty-six one-day old Indian River straight run broiler chicks were randomly allotted to four dietary treatments each of four replicates of 16 chicks each providing floor space of 1115 cm<sup>2</sup> per bird. The basal diet was corn-soya and it was supplemented with different probiotics to make test diets. The dietary treatments were: basal diet (T<sub>1</sub>); basal diet supplemented with probiotic-1 (PB-1) at 1.0 g/kg feed (T<sub>2</sub>); basal diet supplemented with probiotic-2 (PB-2) at 1.0 g/kg feed (T<sub>3</sub>); basal diet supplemented with probiotic-3 (PB-3) at 0.5 g/kg feed (T<sub>4</sub>). Birds were fed starter diet from 0-21 days of age and grower diet from 22-42 days of age. Records were kept of performance traits and carcass yields by maintaining birds under identical management. Profitability was determined on termination of the trial. Performance and carcass yield data were statistically analyzed employing SAS Computer Package Program (SAS, 2009). Results showed no variation (P&gt;0.05) in growth performance and meat yield characteristics of commercial broilers irrespective of types of probiotic supplementation. However, feed intake increased (P&lt;0.05) due to supplementation of probiotics. Although higher cost (p&lt;0.05) incurred due to addition of probiotics in the diet, such an addition increased profit. Profit over control was BDT 12.20/bird (BDT 5.10/kg) in PB-1, BDT 18.70/bird (BDT 7.40/kg) in PB-2 and BDT 17.10/bird (BDT 6.40/kg) in PB-3 group. The profit was higher in all the treated groups over control indicating that the use of probiotics irrespective of type was profitable and cost effective.</p> <p><strong><em>Bang. J. Anim.

A total of 1,020 day-old Cobb 500 male broiler chicks were randomly allocated to 5 dietary treatments with 6 replications per treatment having 34 chicks in each pen. The five dietary treatments were: (i) basal diet without AZOMITE<sup>®</sup>, (ii) basal diet with 0.25% AZOMITE<sup>®</sup>, (iii) basal diet with 0.50% AZOMITE<sup>®</sup> which was recommended by manufacturer, (iv) basal diet with 0.75% AZOMITE<sup>®</sup> and (v) basal diet with 1.0% AZOMITE<sup>®</sup>. Broilers were reared in open-sided gable type house for a period of 32 days. Results showed that the supplementation of AZOMITE<sup>®</sup> had significant effect on growth performance (p&lt;0.01) of broilers. Live body weight (LBW), body weight gain (BWG), average daily gain (ADG), feed intake (FI), feed conversion ratio (FCR), European efficiency factor (EEF) and gain cost of the birds fed various levels of AZOMITE<sup>®</sup> were significantly improved as compared to the control. Meat characteristics results indicated that the treatments had no significant effect on dressing percent, thigh, drumsticks and breast percentage among the dietary groups. Taken together, it may be concluded that the supplementation of AZOMITE<sup>®</sup> in commercial broiler at 0.50 to 1.0% improved live weight, feed intake and feed conversion ratio of commercial broilers.</p> <p><strong><em>Bang.

Sausages were prepared into three different groups: control; broiler breast meat sausage without any flour (T<sub>1</sub>), sausage with addition of 10% rice flour (T<sub>2</sub>) &amp;10% wheat flour (T<sub>3</sub>). All parameters were analyzed at 0, 15<sup>th</sup> and 30<sup>th</sup> days of storage period. The proximate compositions of different sausages were analyzed and highly significant (p&lt;0.01) differences were found in DM (%) and CP (%). Significantly (p&lt;0.01) lower DM (%) and higher CP (%) was found in T<sub>1</sub>. Both DM (%) and CP (%) content were increased with increase of storage time. The storage period have significant (p&lt;0.01) effect on different biochemical (FFA, POV and TBARS value) and microbial (TVC, TCC and TYMC) test. In both cases the values were increased with increase of storage period. Different types of sausage and storage period have an effect on redness (<em>a*</em>) value. In sensory analysis, significantly lower flavor, juiciness and tenderness were found in T<sub>1</sub>. Although flavzAQAor, juiciness and tenderness were varied during sensory evaluation, overall acceptability did not differ among the three treatments. Results of this study revealed that low fat chicken sausages can be made with 10% rice and wheat flour without lowering the overall acceptability.</p> <p><strong><em>Bang. J. Anim.

A total of 200 straight run day-old chicks (Cobb-500) were divided into five treatment groups; T<sub>0</sub>=Basal diet, T<sub>1</sub>= Basal diet+10 ppm neem leaves extract, T<sub>2</sub>= Basal diet+10 ppm garlic leaves extract, T<sub>3</sub>= Basal diet+10 ppm plantain leaves extract, T<sub>4</sub>= Basal diet+10 ppm antibiotic growth promoter (AGP) each with four replications having 10 birds per replicate. All the herbal extracts and AGP were supplemented in drinking water. Ration in the form of crumble was offered to the birds ad libitum having ME=3060 kcal/kg and CP=22.5%. Body weight and feed intake were recorded weekly to calculate body weight gain (BWG) and feed conversion ratio (FCR). A total of 15 birds three from each treatment were sacrificed at the end of feeding trial and dressing parameters were evaluated. Sensory properties of broiler meat were assessed by a panel of experts. Feed intake, BWG and FCR varied (p&lt;0.05) in all treated groups, and the higher BWG and improved FCR were found in AGP group. Triglyceride and very low-density lipoprotein content were lower (p&lt;0.05) in all herbal treated groups than the control and elevated at AGP group. However, increased (p&lt;0.001) dressing percentage and abdominal fat deposition were found in AGP group compared to herbal treated groups and the least value was found in plantain group which also exhibited lower (p&lt;0.001) meat ether extract. Flavor (p=0.001), juiciness (p=0.002), tenderness (p=0.005) and overall acceptability (p&lt;0.001) of broiler meat were significantly higher in herbal group over control and AGP group. The aqueous herbal extract supplementation could be an alternative to antibiotic growth promoter to enhance growth performance, plasma lipid profiles as well as to reduce abdominal fat and meat of either extract.</p> <p><strong><em>Bang.

The experiment was done for a period of 32 days with 384 one-day-old straight run broiler chicks. The broiler chicks were divided into six groups each of 64 birds and replicated to four subgroups each of 16 birds. The dietary groups were; control (basal diet; no additives), antibiotic (basal diet + antibiotic), garlic in feed (basal diet + 0.25% garlic powder), garlic in water (basal diet + garlic extracts), neem in feed (basal diet + 0.25% neem powder) and neem in water (basal diet + neem extracts). Results showed that the body weight and body weight gain increased significantly (<em>P</em>&lt;0.05) in both the garlic and neem groups compared to the control group. Feed intake was not different (<em>P</em>&gt;0.05) among the treatment groups. Garlic in feed and water and neem in feed groups showed better FCR (<em>P</em>&lt;0.05) compared to the other treatment groups. There were no significant (<em>P</em>&gt;0.05) difference in meat yield, bone development and dressing parameters except head and gizzard in different dietary groups. Supplementation of garlic with feed and water significantly (<em>P&lt;</em>0.05) decrease cholesterol, triglyceride and LDL compared to the other groups. However, both the garlic and neem groups showed numerically higher HDL compare to the control group. There were no 0significant (<em>P</em>&gt;0.05) differences in serum glucose and GPT among different treatment groups. GOT was significantly (<em>P</em>&lt;0.05) lower in neem groups than that of garlic and antibiotic groups. Additive groups showed higher profitability than control group. Based on the results of the study, it may be suggested that the garlic and neem could be used both in feed and water as potential feed additives for safe broiler production.</p> <p><strong><em>Bang.

Bhola (AEZ-18, Coastal area), Mymensingh (AEZ-22, River basin area) and Dinajpur (AEZ-27, Drought area). Data on availability, amount and types of feeds and fodders fed to the lactating buffaloes, body weight, milk yield and quality and lactation length were collected from 30 farmers of the each selected locations. In this investigation, the mostly used feed ingredients found were rice straw, locally available green grasses, wheat bran, broken maize, mustard oil cake and broken rice.&nbsp;Total feed supply (DM kg/h/d) to lactating buffaloes were 17.4, 14.5 and 13.0 in coastal, river basin and&nbsp;&nbsp;drought areas, respectively, (p&gt;0.05). But significantly (p = 0.000) different amount (DM kg/h/d) of concentrate were supplied in coastal (1.5), river basin (1.8) and&nbsp;drought (2.7) areas. The highest amount (kg/h/d) of green grass&nbsp;was supplied in coastal area (5.0) followed by river basin area (4.3) and drought area (1.3). Accordingly, amount (kg/d) of DCP and TDN were supplied was higher in coastal area (0.365 and 6.417, respectively) than that of the river basin and drought areas (0.247-0.248 and 5.501-5.891, respectively), which were below their requirements. Significantly (p=0.000) larger lactating buffaloes were found in the river basin and drought areas (weighed 372–380 kg/h) than that of coastal area (242 kg/h). The average daily milk yield was found significantly highest (p=0.000) in the drought area (5.3 L/d) which was&nbsp; 1.4 L and 3.1L more than that of the river basin and coastal area, respectively. The 4% FCM yield was found two times more (p=0.000) in drought area (7.7 kg/d) than that of the coastal (3.1 kg/d) and river basin (3.6 kg/d) area. On the other hand, the significantly (p=0.000)&nbsp; highest lactation length and lactation yield were 294 d and 1085 L, in the river basin area, which were 189 d and 1007 L in drought area and 197d and 429 L&nbsp; in coastal area, respectively. Among the milk constituents, protein, ash and lactose content was found higher in drought area than that of the other two areas (p=0.001). In conclusion, the prevailing variations are evidently considerable.

Thirty-two (32) healthy crossbred lactating cows of Holstein-Frisian (HF), Jersey (J), Sindhi Sahiwal (SS) and Red Chittagong (RCC) were selected for the study and divided into four (04) groups. The cows were allowed to feed and manage according to dairy farm own scheduled-ration. The collected blood samples were analyzed for hematological and biochemical parameters viz. Hemoglobin (Hb), Packed cell volume (PCV), Total leukocyte count (TLC), and Total erythrocyte count (TEC) and Serum urea, Glucose, Albumin, Calcium, and Phosphorus, respectively by using an automated chemistry analyzer. The results revealed that the hematological and biochemical parameters non-significantly (p&gt;0.05) differed between the crossbred groups. From the experiment, the higher amount of Hb (11 g/dL) and PCV (40%) was found in HF and RCC cows, respectively. The TLC was higher in SS and RCC but the TEC was recorded stable along with a slight increment in RCC. As far as the biochemical parameters are concerned, the blood urea concentration was found higher (28 mg/dL) in HF and RCC lactating cows. The same pattern was observed in the case of albumin concentration. On the contrary, the lowest value of Calcium was found in RCC but the Phosphorus concentration showed a little higher in RCC.

The present study describes the dairy characteristics and estimates the financial profitability of dairy farming in selected milk pocket districts of Bangladesh. Following study areas- Sirajganj, Bogura, Rangpur, Satkhira and Munshiganj districts were selected based on the fastest growing dairying, abundant number of dairy farms and contribution in national milk production. Two hundred and sixty-five (265) dairy farms were selected across the study areas and data were collected through direct interview method. The study revealed that dairy herd sizes from the surveyed farms varied from 5 to 19 per farm. Average milk productivity was found 7 to 10 L per cow per day, in which Satkhira district cow’s milk productivity per day (10 L/cow/d) and lactation (3,116 L/cow/lactation) was found the highest and Rangpur district was the lowest. On the contrary, significantly (p=0.000) highest milk production per farm per lactation was in the Rangpur district (33,697 L) and the lowest in the Bogura district (9,818 L). Results revealed that statistically (p=0.000) higher income generated in Munshiganj district in terms of per cow per year and/or per day compared to the other milk pocket districts. The study also indicated that repeat breeding cost and unavailable income per farm per year were higher in the Sirajganj district and lowers in the Bogura district. Repeat breeding problems increases the production cost of the animals significantly (p=0.000) and negatively affect the farm profitability of the milk pocket areas in Bangladesh. Annually gross margin and net return per cow were statistically (p=0.000) higher in Munshiganj district. Benefit-cost ratios were found more than one and indicated that benefit is much higher than the cost of production at Satkhira (annual BCR/farm=1.52) and Munshiganj districts (annual BCR/farm=1.50) compared to the other areas (0.27–0.35 units more). Dairy farming provides higher economic benefits to the farmers of Munshiganj and Satkhira districts compared to the other milk pocket districts. The research concludes that there is an ample scope and possibility for sustaining and developing dairy farming in the milk pocket districts of Bangladesh. Overall, it may be suggested that the causes of repeat breeding should be identified and corrected accordingly within the shortest possible time for the betterment of dairying. Also, milk prices should be similar across the milk pocket districts and essential inputs prices should be kept within the affordable purchase range of farmers for sustainable dairying.</p> <p><strong><em>Bang.
