(Lincoln College, University of Canterbury, 1988)The difference between sheep and deer in the effects of molybdenum (Mo) and sulphur (S) on copper (Cu) metabolism was investigated in two dietary experiments (Chapter 4) using 8 animals of each species. In Exp 1 the animals were offered hay diet containin ...

(Lincoln University, 2015)Wool has unique attributes, but to compete with synthetics, the wool industry is looking for ways to improve their product. The use of gene-markers is one of improving the selection of genetically superior stock. The Keratin-associated proteins (KAPs) are ...

(Lincoln University, 2014)Animal growth and carcass composition are of commercial importance for sheep meat production. Growth and fat deposition are affected by both environmental factors and genetic factors. Genetic selection to produce leaner, fast growing lambs has a long-term ...

(Lincoln College, University of Canterbury, 1988)The interrelationship between copper oxide wire particles (COWP) treatment and parasitic infection was investigated. Particular emphasis was given to the effect of elevated abomasal pH due to parasitic infection on the solubility of COWP. In addition, the ...

(Lincoln College, University of Canterbury, 1983)Two experiments were conducted to examine the interrelationships between body composition at parturition, herbage allowance during lactation and milk production. Detailed measurements of feed intake and changes in body composition allowed estimates of mai ...

(Lincoln University, 1998)Four trials were conducted to investigate the role of nutrition in the periparturient breakdown of resistance to gastrointestinal parasitism in mature sheep. In the first trial pregnant ewes were housed seven weeks prior to parturition and fed either to g ...

(Lincoln University, 1997)Two consecutive experiments were conducted to test a hypothesis that mixed grazing outcome is influenced by the type of stocking system applied. The objective of both experiments was to investigate the influence of co-grazing with sheep on cattle liveweig ...

(Lincoln University, 1994)Wool strength is a heritable trait and varies widely between individuals even when they are maintained under equivalent conditions nutritionally. Consequently, it is valid to search for genetic markers of wool strength with the aim of using them in improv ...

(Lincoln College, University of Canterbury, 1988)Two studies were undertaken examining change in bone and muscle under different growth regimes. In the first study, ontogenetic growth of bone and muscle was examined over the range of liveweight (LW) 5 kg to 67 kg. A second group of animals were subjecte ...

(Lincoln College, University of Canterbury, 1980)Glucose metabolism was studied in fed, starved and toxaemic ewes in the last month of gestation to ascertain causes of hypoglycaemia, and to determine whether the glucose metabolism of sheep susceptible to ovine pregnancy toxaemia (OPT) differs from those ...
