Variation in the stearoyl-CoA desaturase gene (SCD) and its influence on milk fatty acid composition in late-lactation dairy cattle grazed on pasture
(Copernicus Publications on behalf of the Leibniz Institute for Farm Animal Biology (FBN), 2020-11-03)
Gene markers have become useful tools for improving animal genetics and breeding since they improve the accuracy of selection for superior breeding stock. In this study, the stearoyl-CoA desaturase (Δ-9-desaturase) gene ...
Identification of novel nucleotide sequence variations in an extended region of the bovine leptin gene (LEP) across a variety of cattle breeds from New Zealand and Nigeria
(Copernicus Publications on behalf of Leibniz Institute for Farm Animal Biology (FBN), 2020-07-22)
Leptin is mainly secreted by white adipose tissue in animals. Leptin acts by stimulating or inhibiting the release of a neurotransmitter, which eventually results in a decrease in food/feed intake and an increase in energy ...
Implications of water quality policy on land use: A case study of the approach in New Zealand
(CSIRO publishing, 2020-10-22)
Achieving good water quality through output controls is difficult. The New Zealand Government recently proposed enforceable bottom lines to protect ecosystem health of 1 mg L⁻¹ dissolved inorganic nitrogen (DIN) and 0.018 ...
Liveweight gain and urinary nitrogen excretion of lambs grazing diverse (plantain, Italian ryegrass and red clover) or ryegrass-white clover pasture in autumn
(New Zealand Society of Animal Production (Inc), 2020-09)
The objective of this study was to investigate the effect of grazing a diverse pasture of plantain, Italian ryegrass, and red clover versus a ryegrass-white clover pasture on the liveweight gain (LWG) and urinary nitrogen ...
The potential of gender-sorted semen for improving dairy farm profitability, efficiency and genetic gain in New Zealand : A dissertation submitted in partial fulfillment of the requirement for the Degree of BAgrSc (Honours)
(Lincoln University, 2012)
Gender sorted semen, or "sexed-semen" is a new biotechnology available in New Zealand. There are potential benefits associated with its use on dairy farms, including a greater number of heifer calves born allowing for ...
The potential of culinary vegetable oils as herbicides in organic farming: The effect of oil type and repeated applications on plant growth
(Springer Verlag, 2018-03-10)
This study tested the herbicidal effects of raw and processed culinary oils (rapeseed oil, sunflower oil, olive oil, flax/linseed oils) on nine plant species (poppy, white clover, alyssum, lupin, buckwheat, mustard, oats, ...
Maximising the subterranean clover content on a summer-dry Wairarapa hill-country farm through grazing management
(New Zealand Grassland Association, 2019-11-04)
Tokaroa Farm is a 608-ha sheep and beef farm, in the Wairarapa. Paddock slopes range from flat to steep (>25°) with a predominance of gentler north facing slopes and steeper south facing slopes. Annual rainfall is 810 mm ...
