Development of an experimental approach to measure vitamin B12 production and absorption in sheep
(Lincoln University, 2009)
Clinical diagnosis of vitamin B12/cobalt (Co) deficiency is difficult due to the unspecific nature of the clinical symptoms. The apparent increase in vitamin B12 deficiency in New Zealand in the late 1990’s made it clear ...
An evaluation of the use of the nitrification inhibitor dicyandiamide (DCD) to reduce nitrogen losses from intensive sheep winter grazing systems : a dissertation submitted in partial fulfilment of the requirements for the degree of Bachelor of Agricultural Science with Honours at Lincoln University
(Lincoln University, 2009)
The intensification of modern pastoral agriculture has led to an increase in nitrate (NO₃⁻) leaching and nitrous oxide (N₂O) gas emissions from animal grazing systems, leading to environmental degradation. The use of ...
Is increasing ewe prolificacy the key to increasing Canterbury dry land farm profitability? Research using linear programming as a modelling tool : a dissertation submitted in partial fulfilment of the requirements for the degree of Master of Applied Science at Lincoln University, Canterbury, New Zealand
(Lincoln University, 2009)
The sheep industry contributed $3.47 billion in export earnings for New Zealand in 2007. Canterbury produced 22.6% of the lambs born in the 2007/08 season, making it a significant region for lamb production. Increasing ewe ...
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 ...
