However, information on the foliage-development pattern of browse species and appropriate time to begin harvesting/browsing with small ruminants is lacking. Study objectives were to 1) determine the growth pattern of browse species available in grazing lands, and 2) evaluate small ruminants’ preference for these species. Browse species present in woodland (2.8 ha) and browse-research (5.2 ha) sites were identified and tagged in early-winter, 2019. The date when the first leaf-sprout occurred was recorded, and the canopy-development data taken fortnightly after the first sprout until the full canopy was attained. Eight Kiko wethers and five Katahdin rams were co-stocked rotationally in three woodland plots (0.4 ha each) from mid-May to mid-October 2019. The extent of defoliation (0-5: 0 - no defoliation, 5 - 80-100% defoliation) of browse species by animals was assessed. Canopy-development data were analyzed using the GLM procedure and plant-preference data with Mixed procedure in SAS 9.4. Nine species began sprouting in early February, seven by mid-March, and three by late April. Species varied in attaining the full canopy ranging from April 21 to May 21. Animals showed high preference for eight species, moderate preference for nine, and least preference for 11. Results show that browse foliage can be ready for harvest beginning late April to mid-May depending on the browse species. Moderate to highly preferred species can be used to develop browse program or manage these species with small ruminants if present in woodlands.","PeriodicalId":241598,"journal":{"name":"Global Journal of Agricultural and Allied Sciences","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121356596","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}

Farmers and agri-entrepreneurs are demanding trustworthy and efficient extension and advisory services that they can rely on to improve their farming systems and associated enterprises. In this context, extension professionals are expected to be versatile and be competent in their services. Competency refers to having required knowledge, skills and abilities in both process skills and technical subject matters to effectively deliver assigned services. Competency needs are context specific and dynamic. Thus, it is imperative to periodically examine what competencies extension professionals possess and how they value them. This cross-sectional study sought to examine the perceived importance of key competencies among agricultural extension professionals in Nepal. Extension professionals in Nepal’s public agricultural and livestock development offices and agriculture-based non-governmental organizations comprised the study population. Survey data were collected from August to September 2015 through self-, group-administered, and web-based questionnaire. The respondents rated eight core competencies as important or very important. Their perceptions of the importance of these core competencies significantly differed across their current positions, level of education, age, and experience in extension services but not across their educational institutions, employers, and gender. There is a need to develop extension education curricula integrating these core competencies and providing education and training on these core competencies to extension professionals.","PeriodicalId":241598,"journal":{"name":"Global Journal of Agricultural and Allied Sciences","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130275865","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}

Nepal is self-reliant in poultry meat and egg production. This sector provides employment to thousands of people and has become a major source of income to rural people. Low investment cost, less manpower requirement, and quick returns attract many investors towards poultry farming and hence the population and productivity of poultry is increasing year after year. Different viral, bacterial, protozoal and fungal diseases, including influenza, fowl typhoid, coccidiosis and mycotoxicosis, cause tremendous economic loss to the poultry sector of Nepal each year. Vaccines can be an effective preventive measure against poultry diseases and Nepal government together with the private sectors produce vaccines against different poultry diseases. Still, poultry vaccine production within the country is not enough and depends on imports from other countries. Considering the continuous growth in the poultry production and constant threat of disease outbreaks, government of Nepal as well as private sectors should invest more on vaccine production within the country. This article explains the current status of poultry production and vaccine development in Nepal.","PeriodicalId":241598,"journal":{"name":"Global Journal of Agricultural and Allied Sciences","volume":"119 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129981367","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}

However, not much attention has been given to utilize these resources well. The objectives of the current study were to evaluate the potential of increasing the a) light influx to the woodland floor and b) understory vegetation biomass by altering the height of non-timber (non-pine) plants. The study was conducted in six woodland plots (0.4-ha each) consisting of southern pines, hardwoods, and numerous understory plant species. The non-pine plants were either left uncut (control) or cut to one of the heights from the ground: 0 m, 0.9 m, and 1.5 m (treatments) in summer 2016. Kiko wethers (8) and Katahdin rams (5-6) were rotationally stocked in the study plots (3 plots per animal species) during 2017 and 2018. Photosynthetically active radiation (PAR) data were collected before and after stocking animals and the understory vegetation biomass samples were collected before stocking animals in the study plots. The PAR influx in areas that received cutting treatments increased by 413-1723% when measured before grazing, and by 543-2223% when measured after grazing compared to the control. Similarly, the productivity of understory vegetation biomass was 36-107% greater in the cutting treatment areas compared to the control. The findings suggest that the maintenance of non-pine plants at low heights can significantly increase the PAR influx to the woodland floor, thereby enhancing the productivity of understory vegetation and grazing opportunity for small ruminants.","PeriodicalId":241598,"journal":{"name":"Global Journal of Agricultural and Allied Sciences","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127126634","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}
