Comparison of measured and EF5-r derived N₂O fluxes from a spring-fed river
(Blackwell Publishing, 2006)
There is considerable uncertainty in the estimates of indirect N₂O emissions as defined by the Intergovernmental Panel on Climate Change's (IPCC) methodology. Direct measurements of N₂O yields and fluxes in aquatic river ...
Lime and soil moisture effects on nitrous oxide emissions from a urine patch
(Soil Science Society of America, 2004)
Liming has been mooted as a mitigation option for lowering soil N₂O emissions. This study investigated the effect of soil pH and soil water content on N₂O and N₂ emissions following the addition of synthetic urine (500 kg ...
Estimates of the nutritional cost of the development of immunity to gastrointestinal parasites in sheep
(Lincoln University, 2005)
This thesis describes a series of three experiments designed to estimate the nutritional cost of the immune response to the gastrointestinal nematodes Trichostrongylus colubriformis and Teladorsagia circumcincta in sheep. ...
The human face of once-a-day milking
(Lincoln University. Agriculture and Life Sciences Division, 2007-10)
This report concerns exactly what the title The Human Face of Once-a-Day Milking
suggests: the impact of Once-a-day milking on farmers, their families and staff. It is a
document about people: their needs, values, and the ...
The effect of vaccinating infection during pregnancy and dietary protein supply on the peri-parturient immune response of sheep to infection with Teladorsagia circumcincta and Trichostrongylus colubriformis larvae
(Cambridge University Press, 2007-03)
It is well established that dietary protein supply can influence the peri-parturient breakdown of immunity to nematode parasites
but there is no information on the importance of exposure to nematode larvae during pregnancy ...
Leptin concentrations and the immune-mediated reduction of feed intake in sheep infected with the nematode Trichostrongylus colubriformis
(Cambridge University Press, 2009)
The hypothesis that increases in the concentration of the anorectic peptide leptin may be responsible for the immune-mediated reduction in feed intake (FI) during gastrointestinal parasitism in sheep was investigated. In ...
A history of grape production and winemaking in Canterbury, New Zealand 1840-2002
(Lincoln University. Farm and Horticultural Management Group, 2002)
Grapes were first planted in Canterbury in 1840, but commercial production only began
in 1978. This research paper examines the history of grape and wine production in
Canterbury. It considers the different factors ...
Dairy farmers as employers in Canterbury
(Lincoln University. Farm and Horticultural Management Group, 2004-03)
This study establishes base data and determines the actual staff management practices followed by a sample of dairy farmers in Canterbury. A person-centred approach was followed in which respondents were simply asked what ...
The effect of concurrent corticosteroid induced immuno-suppression and infection with the intestinal parasite Trichostrongylus colubriformis on food intake and utilization in both immunologically naïve and competent sheep
(Cambridge University Press, 2005-02)
The nutritional cost of both the acquisition and maintenance of immunity to gastro-intestinal nematodes was investigated using immunologically naïve 5-month-old lambs and immunologically competent 17-month-old ewes. Within ...
The demise of the farm labourer and the rise of the food technologist : a century of radical change in farm employment, 1900-1999
(Lincoln University. Farm and Horticultural Management Group, 1999-07)
This paper reviews changes in farm employment over the 20th Century by viewing farm work as it was around 1900 and how it is appearing to be by 1999 through the eyes of contemporary observers. Then changes in work and ...
