The study was conducted on apparently healthy 24 Murrah buffaloes running on different parities selected from 3 different farms in the Chitwan district of Nepal to find the relation between phenotypic characteristics of udder and milk yield. The shapes of the teat and udder were evaluated by a visual appraisal that revealed 42.7% funnel, 26% bottle, 16.7% cylindrical, 14.6% conical-shaped teats, and 37.5% round, 33.3% bowl, and 16.7% goaty, and 12.5% stepped shaped udders. The average length, width, and depth of the udder were determined as 54.50±0.92 cm, 19.33±0.46 cm, and 27.50±1.10 cm, respectively, while the respective length and diameter of the teat were 8.46±0.17 cm and 3.59±0.07 cm. Within udder quarters, teat length was significantly different (p < 0.05) though the diameter was non-significant. However, the teat length and teat diameter differed along the teat and udder shapes showing the highest measures at bottle-shaped teats and goaty-shaped udder. The average milk yield/day recorded was 5.90±0.36 kg per buffalo. Higher milk yield was observed in the round-shaped udder and conical-shaped teat. The correlation of udder width (r= 0.237, p<0.05) and teat length (r= 0.222, p<0.05) was observed significantly positive but that of teat to floor distance (r= -0.232, p<0.05) was negative with milk yield. Hence, the selection of Murrah buffaloes for milk production traits should consider the dimensions of the teat and udder.","PeriodicalId":15865,"journal":{"name":"Journal of Fujian Agriculture and Forestry University","volume":"8 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84630205","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}

Full blossomed A. houstonianum was fed ad libitum to six goats until the death of the animals. The time to develop the clinical signs and symptoms in goats ranged from 22 to 49 days. All the goats exhibited similar symptoms and signs such as stiffness of the neck, low temperature, respiratory distress, low pulse, anorexia, ruminal atony, general weakness, and finally, recumbency till death. After the onset of clinical symptoms, the entire clinical course persisted for 10-15 hours, followed by death. Two goats died on the 22nd day, and the rest goats died on 27th, 46th, 48th, and 49th days respectively. Hematologic examination revealed a significant decrease in hemoglobin and an increase in total WBC count. The serum biochemical values showed substantial alterations in ALT, AST, ALP, GGT, albumin, direct bilirubin, total bilirubin, glucose, urea nitrogen, and creatinine concentrations. These biochemical changes suggested hepatic and renal dysfunction. Therefore, clinical signs, hematology, and serum biochemistry can be of optimal diagnostic value for the A. houstonianum intoxication in goats.","PeriodicalId":15865,"journal":{"name":"Journal of Fujian Agriculture and Forestry University","volume":"31 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86705582","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}

Sucking pests like aphids, whiteflies, thrips, mites, etc. are the major insect pest in sweet pepper fields. Farmers deliberately have been using chemical pesticides in their crop to manage various insect pest and such practices of using hazardous chemicals are harmful to human health and the biodiversity. Similarly, farmers don't have an idea of planting trap and/or companion plants and its role in natural control of pest. Hence, a study was conducted to know the population dynamics, especially to assess the aphid (Myzus persicae, Sulzer) population and its potential natural enemies by planting rapeseed as companion crop. This field experiment was conducted in six different locations of Bharatpur-23, Chitwan from Nov 2019 to Jan 2020 where three plots of sweet pepper were planted with rapeseed as companion crop and other three plots solely having no floral source around. Aphid population was recorded at weekly interval and its major natural enemies; ladybird beetle and syrphid fly. Abnormal data were squared root transformed and analyzed by using paired sample t-test. The result showed that the aphid population in sweet pepper field with companion crop was significantly lower than in sweet pepper grown without floral source (control). Highly significant number of ladybird beetles and syrphid flies were recorded in sweet pepper with companion crop compared to control. The finding is helpful to develop an integrated management protocol of sweet pepper pests with the practice of following conservation biological control strategy.","PeriodicalId":15865,"journal":{"name":"Journal of Fujian Agriculture and Forestry University","volume":"22 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77676143","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}

Likewise, Emamectin benzoate and Chlorantraniliprole also caused > 90% mortality within twenty-four hours. Azadirachtin and Imidacloprid were not as effective as other pesticides that caused only 17% larval mortality in the first twelve hours and 68% mortality in sixty hours. Similarly, Imidacloprid caused 8% larval mortality in twelve hours and 59% mortality in sixty hours. There was no mortality in water spray (control).

Data were collected using a pre-tested interview schedule and focus group discussion (FGD) in 2017. The result of t-test showed annual household income, income from milk sell, and average cattle holding significantly higher in cattle insurer farmers than that of non-insurers. A probit model was used to assess the factors affecting the decision for the adoption of cattle insurance. The probit model revealed that cattle breed, access to loan, income from livestock, and number of cattle had a positive and significant relationship with the adoption of cattle insurance whereas, household size and district dummy had a negative and significant relationship with the adoption of cattle insurance. Income regression function revealed that the adoption of insurance, the number of cattle, and the district of the respondents had a positive and significant relation with income from livestock. The instrumental variable model adopted to combat endogeneity bias showed that adoption of insurance and district of the respondents had a positive and significant relation with income from livestock.

Nowadays, maize production is threatened by one invasive pest, the fall armyworm (Spodoptera frugiperda) particularly in Africa and Asia, and threatens millions of poor people. Fall armyworm feeds a wide range of crops and non-crops including weeds, with over 353 plant species. But most frequently consumed crops are field corn, sweet corn, wheat, sorghum, sugarcane, Bermuda grass etc. Fall armyworm has six larval stages, the first three stages are less voracious compared to the latter stages. Larvae are very numerous and disperse in large numbers and behave like ‘armyworm’. Insecticides are considered an important tool of FAW management as well as other lepidopteran maize pests. However, these practices are not sustainable and are linked to the environment, biodiversity and farmers' health. Alternative management strategies should be developed by understanding pest biology and ecology. Hence, a series of laboratory choice and paired-choice tests were conducted at Agriculture and Forestry University in May 2021 to evaluate the host plant preference by the fall armyworm. Potential host plants were Zea mays (maize cultivars - Rampur composite, Arun-2 and Rampur hybrid-10), Pennisetum purpureus (Napier), Oryza sativa (rice), Sorghum bicolor (Sorghum), Fagopyrum esculentum (Buckwheat), Vigna unguiculata (Cowpea) and Glycine max (Soybean). In choice tests, FAW preference was ranked as Rampur Composite > Sorghum > Rampur hybrid-10 > Arun-2 > Napier > Rice > Buckwheat > Cowpea > Soybean. Rampur composite and sorghum were the most preferred host plants, Rampur hybrid, Arun-2 and Napier were the medium preferred, rice was categorized as the low preferred and other host plants such as buckwheat, cowpea and soybean were the least preferred host plant of fall armyworm. In paired-choice tests, Rampur composite was more preferred than sorghum, but not significantly so. These research findings are useful to utilize in habitat manipulation strategies for fall armyworm management. Most preferred plant species can be deployed as trap crops and least preferred host plants can be used as repellent or push crops in a push-pull strategy. Such host plants in-and-around the main field can reduce the fall armyworm damage and reduce pesticide amount in main crops.","PeriodicalId":15865,"journal":{"name":"Journal of Fujian Agriculture and Forestry University","volume":"105 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80696019","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}

Pretested semi-structured interview schedule was employed to collect data from 390 sample respondents selected randomly. Descriptive statistics and the appropriately developed scales were used in the data analysis. Moreover, respondents considered lack of awareness along with its requirement of skilled human resources and its cost were the primary reasons for the rejection of the use of ICT tools, where the overall rejection level was at a medium level. The constraints level of the use and adoption of farm machinery was found high; the significant constraints considered by the respondents were the high price of the machinery along with poor skills, knowledge, facilities, and poor maintenance service. The overall index value for the rejection of the use and adoption of farm machinery in paddy farming was at a moderate level. The respondents’ primary reasons for the rejection of the use of farm machinery were the high price of the farm machinery long with poor training, poor skilled human resources, and complex ideas to learn.
