The experiments were carried out at the Agronomy Experimental Field of Patuakhali Science and Technology University, Dumki, Patuakhali in order to evaluate the effect of sowing date and planting density on the yield and yield contributing characters of sunflower varieties. The experiment comprised of two varieties viz. BARI Sunflower2 and Hysun33 and six planting densities viz. 40cm×25cm, 40cm×35cm, 40cm×45cm, 50cm×25cm, 50cm×35cm, 50cm×45cm. The experiment was laid out in a split-plot design with three replications, where the variety was assigned in the main plot and planting density was assigned as sub-plot treatment. Planting density had a significant influence on all the characteristics of morphological growth, yield, and yield contributing character except plant height at 75 DAS and 90 DAS. In case of Hysun33 variety, the highest number of leaves (21.89), leaf area (3214.22 cm2), head diameter (19.27 cm), head weight (539.07 gm), number of seed head-1 (973.33), seed weight head-1 (65.89 gm), thousand seed weight (67.73 gm), total seed yield (3.27 tha-1) and harvest index (34.30 %) was obtained from 50 cm × 45 cm planting density. On the other hand, in case of BARI Sunflower2 variety the highest number of leaves (18.44), leaf area (3342.90 cm2), head diameter (18.73 cm), head weight (457.80 gm), number of seed head-1 (832.17), seed weight head-1 (53.39 gm), thousand seed weight (64.07 gm) was obtained from 50 cm × 45 cm planting density and the highest stover yield (8.04 tha-1) and biological yield (10.73 tha-1) were obtained from 40 cm × 25 cm planting density. The highest total seed yield (2.94 tha-1) was obtained from 50 cm × 25 cm (8 plants m-2) planting density. Vol. 10, No. 3, December 2023: 229-235

The association between body and udder measurements can be used towards the improvement of milk yield. Hence, this study aimed to identify the udder measurement traits and body measurement traits that may be used by farmers to increase milk yield of Holstein cows. The study was conducted at Limpopo Dairy Farm in Makhado Local Municipality at Louis Trichardt, Limpopo Province, South Africa where a total of 50 lactating Holstein cows were used. Pearson’s correlation technique was used for data analysis. Findings between body measurement traits and milk yield showed that milk yield had a highly positive significant (p ˂ 0.01) correlation with rump height (r = 0.55), and positive significant (p < 0.05) with withers height (r = 0.44) and body length (r = 0.42). Results between udder measurement traits and milk yield showed that milk yield had a highly positive significant (p < 0.01) correlation with udder length before milking (r = 0.57), udder circumference before milking (r = 0.55) and udder circumference after milking (r = 0.51) The results also showed that milk yield had a positive significant (p < 0.05) correlation with teat diameter before milking (r = 0.30), teat length before milking (r = 0.31), teat circumference before milking (r = 0.36) and udder length after milking (0.47). The findings imply that all traits correlated with milk yield can be used to enhance milk yield of Holstein cows through selection during breeding. Vol. 10, No. 3, December 2023: 335-340

Arsenic (As) is found in contaminated groundwater as the source of pollution. In this study, 60 Long-Evans rats were used to assess the levels of As in the blood and organs and to compare the effectiveness of vitamin A and spirulina (Spirulina platensis) in preventing a chronic As accumulation. Twelve rats were assigned to each group of animals. The experimental groups were the control (T0), As (T1), As + spirulina (T2), As + vitamin A (T3), and As + spirulina + vitamin A (T4). The T1, T2, T3, and T4 groups were orally administered with sodium arsenite (NaAsO2) @ 4 mg/kg body weight (BW) for 63 days. In addition to NaAsO2, the T2 and T4 received 1 g/kg BW spirulina. The T3 and T4 received 2500 IU/kg BW vitamin A for 63 days, respectively. Four rats were euthanized in each group to evaluate the As concentration in the liver, lung, kidney, and blood at an interval of 21 days. Total As concentration was quantified from the organs using Hydride Generation Atomic Absorption Spectrophotometer (HG-AAS). The results revealed that the T0 had no visible clinical symptoms. However, after 63 days of treatment, the T1 (As only administration) accumulated more As compared to other groups. The concentration of As was highest in the blood, then in the kidney, liver, and lung. In this case, spirulina and vitamin A substantially (p<0.01) decreased the concentration of As in the rats' organs and tissues Spirulina is more effective than vitamin A in reducing As accumulation in rats. In summary, the combination of both spirulina and vitamin A has a positive impact on reducing the accumulation of chronic arsenicosis in rats compared to the individual administration of either spirulina or vitamin A alone.

砷（As）作为污染源存在于受污染的地下水中。在这项研究中，60 只 Long-Evans 大鼠被用来评估血液和器官中的砷含量，并比较维生素 A 和螺旋藻（Spirulina platensis）在预防砷慢性积累方面的效果。每组 12 只大鼠。实验组分别为对照组（T0）、砷组（T1）、砷+螺旋藻组（T2）、砷+维生素 A 组（T3）和砷+螺旋藻+维生素 A 组（T4）。T1、T2、T3 和 T4 组口服亚砷酸钠（NaAsO2）（4 毫克/千克体重）63 天。除 NaAsO2 外，T2 和 T4 组还接受了每千克体重 1 克的螺旋藻。T3 和 T4 分别接受每千克体重 2500 IU 的维生素 A，持续 63 天。每组四只大鼠被安乐死，每隔 21 天评估肝脏、肺脏、肾脏和血液中的砷浓度。使用氢化物发生原子吸收分光光度计（HG-AAS）对各器官中的总砷浓度进行量化。结果显示，T0 没有明显的临床症状。然而，经过 63 天的治疗后，T1 组（只施用砷）与其他组相比积累了更多的砷。血液中的砷浓度最高，然后是肾、肝和肺。在这种情况下，螺旋藻和维生素 A 显著（p<0.01）降低了大鼠器官和组织中的砷浓度。 螺旋藻比维生素 A 更能有效减少大鼠体内的砷积累。总之，与单独服用螺旋藻或维生素 A 相比，螺旋藻和维生素 A 的组合对减少大鼠慢性砷中毒的积累有积极影响。

An experiment was conducted to study the drought tolerance in selected boro rice varieties in pots at the Farm Research Laboratory of Dept. Genetics and Plant Breeding, Bangladesh Agricultural University, Mymensingh in Rabi season of 2014-2015. In this experiment, drought was induced by manipulating the field capacity (30-35% FC as drought, 95-100% FC as control) and moisture content of the soil in the pot. Drought treatment was started 36 days after transplanting and continued till harvest. The work was comprised based on several morphological and biochemical approaches viz. days to 50% flowering, plant height, panicle length, no of total tillers hill-1, no of effective tiller hill-1, days to maturity, no of filled grains panicle-1, no of unfilled grains panicle-1, grain panicle-1, 100 seed weight, grain yield panicle-1, yield hill-1, spikelet fertility, proline and L-ascorbic acid were found to be changed significantly in drought stress as compared to the control. In drought conditions, the highest yield performance was showed in BRRI dhan29 by changing 33.11% compared to its control. Due to drought induction proline accumulation was significantly upregulated by 2.53 and 2.10 folds in BRRI dhan36 and BINA dhan5, respectively and L-ascorbic acid was decreased lowest in BINA dhan10, BRRI dhan50, and BRRI dhan29 by 27.29%, 41.31%, and 43.91%, respectively. This study produced substantial information about the drought tolerance status of the selected boro rice varieties, and therefore, can be an aid for any future attempt to improve the drought tolerance of the studied varieties.

Foot and mouth disease (FMD) is a viral disease that is epitheliotropic and transboundary, affecting cattle, buffalo, sheep, goats, and wild animals all over the world. Due to lower productivity and higher mortality in calves, this highly contagious disease causes significant economic loss. The study was conducted to identify clinical signs, management, complications, and prevalence of Foot and Mouth disease (FMD) in cattle for five months at Bagherpara Upazila, Jashore. A total of 66 cattle of both sexes were investigated clinically. The impact of season, breed, age, sex, and purpose of keeping cattle on disease incidence was investigated. In December, the prevalence of FMD was higher (27.27%). Crossbreds (71.21%) were discovered to be more vulnerable than local breeds (28.79%). Male and adult cattle were found to have a significantly higher prevalence of the disease than females and young cattle. Clinical observations of cattle affected by foot-and-mouth disease showed fever, salivation, erosive lesions in the oral mucosa and the interdigital region of the foot, and lameness. In complicated FMD cases, the antibacterial drug might be advised for clinical use to control secondary bacterial infection. Sulphadimidine, Ampicillin, and Oxytetracycline, as well as other supportive drugs, were used to treat the patient whereas the recovery rate was 90.91%, 77.27%, and 68.18%, respectively.

The study was conducted to compare midline and flank approaches for spaying in cats. Cats were divided into two groups based on surgical approaches for spaying, Group A (Flank approach) and Group- B (Ventral midline approach). To evaluate the best approach for spaying, various parameters such as length of the surgical incision, the extent of haemorrhage, ease of location and exteriorization of ovaries and uterus, duration of surgery, postoperative complications, and time required for complete wound healing were recorded. In addition, the heart rate, respiration rate, and temperature were recorded before the operation and on different days after the operation. The physical parameters significantly (P<0.05) differed between the two groups. In both groups, the average length of skin incision was 2.8 cm. The average time of exteriorization of ovaries and uterus was higher in the ventral midline approach as compared with the flank approach. The average duration of surgery was (23.25±4.20) min in group A and 29·25±4.88 min in group B. The average wound healing time (days) was also higher in the ventral midline approach (16.50±1.26) compared to the flank approach (13.75±7.85). During Spaying in cats, the extent of haemorrhage was mild to moderate in the flank approach, whereas there was no haemorrage or sometimes less in the ventral midline approach. The post-operative complications were less in flank methods than in ventral midline approaches. It is concluded that spaying through the flank approach is superior to the ventral midline approach due to convenience, faster healing, rapid recovery, and fewer postoperative complications.

Cats were divided into two groups based on surgical approaches for spaying, Group A (Flank approach) and Group- B (Ventral midline approach). To evaluate the best approach for spaying, various parameters such as length of the surgical incision, the extent of haemorrhage, ease of location and exteriorization of ovaries and uterus, duration of surgery, postoperative complications, and time required for complete wound healing were recorded. In addition, the heart rate, respiration rate, and temperature were recorded before the operation and on different days after the operation. The physical parameters significantly (P<0.05) differed between the two groups. In both groups, the average length of skin incision was 2.8 cm. The average time of exteriorization of ovaries and uterus was higher in the ventral midline approach as compared with the flank approach. The average duration of surgery was (23.25±4.20) min in group A and 29·25±4.88 min in group B. The average wound healing time (days) was also higher in the ventral midline approach (16.50±1.26) compared to the flank approach (13.75±7.85). During Spaying in cats, the extent of haemorrhage was mild to moderate in the flank approach, whereas there was no haemorrage or sometimes less in the ventral midline approach. The post-operative complications were less in flank methods than in ventral midline approaches. It is concluded that spaying through the flank approach is superior to the ventral midline approach due to convenience, faster healing, rapid recovery, and fewer postoperative complications.\u0000Vol. 10, No. 3, December 2023: 319-326","PeriodicalId":20947,"journal":{"name":"Research in Agriculture Livestock and Fisheries","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139523346","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The demand for jute fiber is increasing instead of synthetic fiber nowadays. Developing an early and high fiber-yielding tossa jute line is the main breeding objective of jute growing areas including Bangladesh. To fulfill that objective, the existing cultivar JRO-524 was irradiated with five (700, 800, 900, and 1000 gy) doses of gamma-ray. A total of 25 M3 plants were first selected from bulked M2 plants. Two years of replicated yield trial experiments were conducted in different locations in Bangladesh. Among them, two mutants BJM-10-1-3 and BJM-10-1-5 were selected for higher fiber and stick yield. The selected mutants BJM-10-1-3 and BJM-10-1-5 showed 4% to 6% higher yield than their parent JRO-524. The mutant line BJM-10-1-5 showed higher fiber percentage (34.04%), fiber fitness (2.65%), and fiber brightness (44.15%). These two mutants have been under participatory varietal trial (PVT) for evaluation to release a tossa jute variety. These lines will play a vital role in reducing the seed import of variety JRO-524 from India. Vol. 10, No. 3, December 2023: 259-268

The experiment was conducted at the agriculture field laboratory of Noakhali Science and Technology University during the period from October 2021 to January 2022 to observe the effect of various doses of cowdung and nitrogen on the performance of mustard. The experiment comprised of two factors viz: cowdung and nitrogen. One organic fertilizer like different level of cowdung-control 0 t ha-1 (C0), 15 t ha-1 (C1), 30 t ha-1 (C2), 45 t ha-1 (C3) and another inorganic fertilizer nitrogen - control 0 kg ha-1 (N0), 100 kg ha-1 (N1), 200 kg ha-1 (N2), 300 Kg ha-1 (N3). The experiment was laid out in Randomized Complete Block Design (RBCD) with three replications. Application of different doses of cowdung and nitrogen significantly influenced the Plant height (cm), branches plant-1 (no.), effective siliqua plant-1 (no.), seeds siliqua-1 (no.), 1000-seed weight (g), seed yield (t ha-1), stover yield (t ha-1), biological yield (t ha-1) and harvest index (%) of mustard. The maximum plant height, number of branches plant-1, number of effective siliqua plant-1, siliqua length, number of seeds siliqua-1, 1000-seed weight, seed yield, stover yield, biological yield and harvest index was obtained with the application of 45 t ha-1 cowdung (C3). On the other hand, with the application of 300 kg ha-1 N the maximum plant height, number of branches plant-1, number of effective siliqua plant-1, siliqua length, number of seeds siliqua, 1000-seed weight, seed yield, stover yield, biological yield was found except the harvest index. In case of the interaction effect of treatment, the highest seed yield (1.77 t ha-1) was obtained from the treatment combination of C3N3 (45 t ha-1 cowdung + 300 kg ha-1 N) and the lowest seed yield (0.93 t ha-1) was found from the control (C0N0) treatment.

Pesticides used in agriculture that wash off have a detrimental effect on freshwater fish in Bangladesh. The purpose of this research is to assess the effects of the organophosphate insecticide Malathion 57 EC on the silver barb (Barbonymus gonionotus). The effects of Malathion 57 EC at dosages of 0.001 and 0.005 ppm, respectively, were assessed using a histological bio-assay of the gill, liver, kidney, and RBC count of B. gonionotus. For B. gonionotus, the LC50 value of Malathion 57 EC was estimated to be 0.08 ppm. The notable alterations included gill clubbing, missing gill lamellae, hyperplasia, nuclear hypertrophy, vacuolation, glomerular enlargement, increasing the width of renal tubules, bleeding, necrosis, and pyknosis were found in the histological analysis. Large lymphocytes, dead cells, tear-shaped cells, a fusion of cells, binucleated cells, ghost cells, senile cells, and irregular cell shapes were among the abnormalities detected in peripheral nuclear erythrocytes. In B. gonionotus, the RBC count was considerably lower (P<0.01) at lower pesticide doses compared to higher ones. The outcome of the study shows that the organophosphorus pesticide has a negative impact on the histology and haematology of various organs in B. gonionotus. Res. Agric. Livest. Fish.

An experiment was conducted at the agriculture research field of Noakhali Science and Technology University, Noakhali-3814, Bangladesh during the period 1st November 2021 to 30 January 2022 to observe the effect of different levels of nitrogen (N) fertilizer on growth and yield of mustard. The experiment comprised four levels of nitrogenous (N) fertilizer viz; control (N0) 0 kg ton ha-1, (N1) 90 kg ton ha-1, (N2) 140 kg t ha-¹, (N3) 190 kg t ha-1. The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. Application of different levels of nitrogen significantly influenced the Plant height (cm), branches plant-1 (no.), effective siliqua plant-1 (no.), seeds siliqua (no.), 1000-seed weight (g), grain yield (t ha-1), stover yield (t ha-¹), biological yield (t ha-1), harvest index (%) content of mustard. Application of 190 kg ha-1 nitrogen gave the maximum plant height (77.83 cm), Branches plant-1 (5.80), Effective siliqua plant-1 (23.60), Siliqua length (6,17 cm), Seeds siliqua (33.87), 1000-seed weight (3.57 g), grain yield (1.53 t ha-1), Stover yield (3.90 t ha-1), Biological yield (5.43 t ha-1) and the lowest yield was found from control (N0) 0 kg ton ha-1. Consequently, ‘BARI SARISHA-14’ may be suggested to grow for higher yield with N3 treatment. Res. Agric. Livest. Fish. Vol. 10, No. 2, August 2023: 99-107
