    IMPACT OF CLIMATE CHANGE ON PEOPLES’ LIVELIHOOD AND LIVESTOCK PRODUCTION IN UGANDA
    (2023-12-30) Wafana, Ivan
    Livestock sector in Uganda contributes significantly towards individual household income and food security and even though peoples’ dependance on livestock production for survival in Uganda is a reality, it’s also undeniable that livestock, which provides food and revenue on a worldwide scale, would be vulnerable to the direct or indirect consequences of climate change. Agriculture contributed 24.1% of the Uganda’s GDP in the financial year (FY) 2021–2022 and according to the Uganda bureau of standards (UBOS), agriculture employs over 70% of Uganda's working population. The purpose of this present study was to to evaluate the impact of climate change on peoples’ livelihood and livestock production in Uganda. Bibliometric analysis was the quantitative technique used for reviewing and describing published publications that assisted in evaluating academic works from secondary data obtained on digital databases in the context of this study. The VOS viewer software was used as a tool to perform the co-occurrence analysis, and then to realize the visualization of the impact of climate change on peoples’ livelihood and livestock production in Uganda using articles analysed on platform research with associated references from the Web of Science database. The visualisation highlighted topical areas that reflect the impacts of climate on peoples’ livelihood and livestock such as diseases, drought, coping strategies, greenhouse gases, drought, vulnerability, dry lands, mobility among pastoral communities, low productivity, reduced forage resources, elevated temperature extra all of which negatively affects the economic levels of individuals and the national income from livestock either directly or directly. Conclusively, interventions that are aimed at improving climate smartness in Uganda’s livestock farming communities may have significant food security and income benefits for different livelihoods.   Keywords: climate, l ivestock animals, livelihood, income

    In this thesis, the effect of organic selenium and vitamin E, yeast strain Saccharomyces cerevisiae - Levucell SB Titan, and Arginine on the sows’ body productivity, body condition and growth rate of piglets, were evaluated. Data from the sows and piglets was collected in four categorical phases starting from the period of gestation, farrowing, lactation, and weaning. The average performance of the sows and piglet attributes to determine the piglets’ immune competence and survivability was analysed using a generalised linear model of SAS Ondemand for Academics (SAS Institute inc, Cary, NY, USA) and the mean differences were tested by Tukey test. Average data was collected on the performance of the sow and piglet parameters like the sow feed intake, sow live weight at the start, sow live weight at weaning, sow backfat at the start of the experiment, sow backfat at the weaning period and the piglet parameters such as the number of total piglets born, number of piglets born alive, number of still born piglets, number of mummies born, number of piglets at egalization, number of piglets at weaning, piglet weight at birth, piglet average daily gain, piglet weight at egalization, piglet weight at weaning. The findings in this study revealed that dietary manipulation of the sows’ diet with organic selenium and vitamin E, yeast strain Saccharomyces cerevisiae - Levucell SB Titan, Arginine Amino acid did not have a significant effect on the sows’ productivity, body condition and the growth rate of piglets.
