The study aimed to explore the business dynamics of Chepa production and marketing, focusing on identifying challenges and issues in the process. In the study, focus group discussion (FGD) and face-to-face interviewing were conducted using semi-structured questionnaires. Additionally, PESTLE framework was employed to assess the operational aspects of the Chepa business. The study identified seven key stakeholders in the different nods of the Chepa value chain, highlighting their role alongside supporting entities. The production process involved careful categorization of dried fish based on size and quality. Notable, women constituted predominant workforce in the midstream segment, especially contributing to fish processing. Unlike other food items, Chepa fermenting processes carried out in treated earthen pots without using any chemicals and pesticide, resulting in a distinctive flavor and color. The study underscores the profitability of Chepa industry, although fishermen earned the lowest profit among the shareholders. Furthermore, the declining populations of small fish in water body like haor, posing a threat to their livelihoods. The PESTLE analysis highlighted the importance of an integrated, and multidisciplinary approach to food safety and quality, stressing the importance of training and institutional development. The outcomes of our study offer valuable insights for policymakers and stakeholders, guiding efforts toward establishing a sustainable and resilient Chepa industry. \u0000Vol. 10, No. 3, December 2023: 353-366","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":"139523544","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}

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).

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.\u0000Vol. 10, No. 3, December 2023: 341-351","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":"139523872","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}

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.\u0000Vol. 10, No. 3, December 2023: 327-334","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":"139610113","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}

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}

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.
