    Assessing the welfare of pasture-based dairy cows of New Zealand and transhumance chauris of Nepal : a thesis presented in partial fulfillment of the requirements for the degree of Doctor of Philosophy in Veterinary Science at Massey University, Runenga Porehuroa, University of New Zealand, School of Veterinary Science, Manawatu
    (Massey University, 2024-06-14) Sapkota, Sujan
    There is no industry-recognized welfare assessment protocol for pasture-based dairy cows of New Zealand. Also, the welfare assessment in yak/chauri raised under the transhumance system is at the preliminary stage. So, there is a strong necessity of a pastured-based welfare assessment protocol for pasture-based dairy cows in New Zealand and transhumance yak/chauri in Nepal. The aim of the research studies presented in this thesis were to develop a practical and time-limited welfare assessment protocol suitable to pasture-based dairy farms, and transhumance yak chauri focused on a single visit around milking. During the process, 84 different welfare measures were collected from six protocols and 4 welfare studies which were screened and trialed in two pasture-based farms to finalise 32 welfare measures including 5 additional measures specific to New Zealand. These measures were tested on 23 different dairy farms from the Waikato and Manawatu. All the measures were feasible except for the measure related to water availability and behavior. Testing of the repeatability and reliability should be performed for all the selected measures on more number of farms before taking this protocol for commercial use. Also, we further did subsampling-based locomotion scoring on five different pasture-based dairy farms to know if they could predict herd level prevalence. The findings were that there was a significant association between the order in which cows were milked and their susceptibility to lameness. However, the percentage of lame cows within the sub-sampled group was not uniform and was significantly influenced by the farm and the timing of the visit. For our yak/chauri protocol, 31 potential welfare measures were submitted to 120 Nepalese experts for evaluation identifying 13 measures, plus a new one (hematology) was deemed useful. The resulting protocol was tested in five chauri herds in northern Nepal, encompassing animal-based evaluations, mastitis and parasite sampling, and hematology. The protocol was found to be feasible and offers a valuable starting point for yak/chauri welfare assessment.

    “Na mata ni Civa au a vakawaletaka” : an ethnobotanical study on kumala (Ipomoea batatas (L.) Lam) and its contribution to climate-smart agriculture in Ra, Fiji : a thesis presented in fulfilment of the requirements for the degree of Doctor of Philosophy in Horticulture, Massey University, School of Agriculture and Environment, Palmerston North, Aotearoa
    (Massey University, 2022) Leweniqila, Ilisoni Lasaqa Vuetinabouono
    Globally, sweetpotato (Ipomoea batatas (L.) Lam) or kumala is regarded as an essential, versatile, and under-utilised food security crop. In Fiji, kumala has a strong traditional base, and our ancestors valued this crop as a lifesaver to people during and after natural disasters to act as food security since both the tubers and leaves are consumed. This research weaves together two methodologies; the Fijian Vanua Research Framework (FVRF) which involves ethnobotany studies, and a western sciences (field trials) research element to support and reinstruct smallholder farmers on the value of kumala as a significant crop for subsistence and a source of livelihood for rural economic development in Fiji. The three research sites were Nabukadra (<20m asl ) located in the coastal land area, Bucalevu (>150m asl) in the high altitude inland, and Burenitu (80-100m asl) in the district of Nalawa which is situated at a lower altitude. The implementation of FVRF in this research paid specific attention to indigenous Fijian society aligning to future food security issues in an agricultural context. This research sought a solidarity approach for the rural areas in Fiji adopting their systems of knowledge and perception as the basis for inquiry extending the knowledge base of indigenous people and transforming their understanding of the social-cultural world like solesolevaki, which is our current cultural currency. The Dre’e metaphor was generated to discuss the findings from this research. The findings of this research discussed the cultural role of kumala production in the I-Taukei context under four components: values and beliefs, practices, skills, and knowledge. Indigenous Knowledge (IK) exists across all facets of the I-Taukei way of life, which includes health, belief system, and environmental survival. Given that each genotype or variety of kumala may respond differently to production factors, there was a need to evaluate available sweetpotato genotypes across geographic zones where it can be grown in Fiji. The application of agronomic field trials at different altitudes for this research provided a valuable recommendation that will assist farmers in decision-making for growing kumala at different altitudes in Ra. This will enhance food security and create economic opportunities. Furthermore, this extension of traditional and agronomic knowledge will support climate-smart agriculture (CSA) and help achieve food security in the province of Ra, Fiji Islands.

    Studies of variation in the rectal temperature, pulse rate, respiration rate and skin temperature of some New Zealand Jersey cows with particular reference to summer climatic conditions : a thesis presented in partial fulfilment of the requirements for the degree Master of Agricultural Science in the University of New Zealand
    (Massey University, 1959)
    The field of research known as Environmental Physiology covers Studies on the physiological responses of animals to variations in their immediate environment and on the adaptation of animals to environment. Generally, studies with cattle in this field have been pursued either in tropical environment or, lately, in very cold climate (see series of papers by MacDonald and Bell, 1958). The use of climatic chambers, such as those described by Brody (1948) and by Findlay (1950), has enabled research workers to study the effects on animals of a wide range of climatic variables but the results have a restricted application in the field.

    Extending the knowledge system and food value of kumala (lpomoea batatas or sweetpotato) in Vanuatu as a response to climate change : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Horticultural Science at Massey University, Manawatū, New Zealand
    (Massey University, 2018) Setak, Patricia
    Loss of traditional knowledge in food production is a major problem occurring in many countries due to modernization and globalization. Additionally, further compelled by the impacts of climate change, this can have a devastating effect on the livelihood of people. As a result, farmers are therefore compelled to revive the use of traditional knowledge in food production especially its blended use with contemporary knowledge in adapting to and mitigating climate change impacts. The aim of this study is to identify the contribution of traditional knowledge of kumala (Ipomoea batatas) production in sustaining the livelihoods of people in Vanuatu. The target population of this study was kumala farmers in two villages: Lorevulko and Sara 1 in East Santo, Vanuatu where qualitative data using semi-structured interviews was obtained. A literature review was also undertaken on kumala production in other countries where kumala is commonly grown. The younger generations should be educated on traditional knowledge and skills, and efforts should be made to document traditional knowledge. Traditional knowledge is being used in the pre-production activities of kumala such as planting calendar, site selection, land clearing and soil preparation. Both knowledge systems are used in the production of kumala for example in kumala cultivar selection, division of labour, planting, crop maintenance, preparation and management of kumala during droughts and cyclones. In addition, both traditional and contemporary knowledge are used in post-production of kumala in different storage methods such as field, bag, basket, and food bed. Overall, the findings in this study confirm compelling evidence that traditional knowledge contributes towards the sustainable livelihood of the people in Lorevulko and Sara 1. It shows that there is an assimilation of knowledge systems and they create a cultural output that is unique to location and time, and provides a good example of cultural dynamics which never stand still and which respond to environmental and other pressures. Findings from this research will contribute immensely in improving food security at the household and national level in Vanuatu, and generate sustainable income for farmers and livelihoods for farmers. Researchers can also use the findings of this study as a basis to undertake further studies on traditional knowledge of kumala in Vanuatu. Moreover, the results will be useful for informing and influencing government policy and farming practices.
