Suppression of vulpia and goose grass in dryland pastures through the choice of sown pasture species
(New Zealand Grassland Association., 2010)
Vulpia (Vulpia myuros) and goose grass (Bromus
hordeaceus) are common annual grass weeds throughout
New Zealand in dryland pastures. They compete with
sown species, suppressing pasture production and
livestock performance. ...
Development of a forage evaluation system for perennial ryegrass cultivar and endophyte combinations in New Zealand dairy systems
(New South Wales Department of Primary Industry, 2013-09)
An economic index for perennial ryegrass (Lolium perenne L.) cultivars is a relatively new concept, although recently introduced in Ireland (McEvoy et al. 2011). By contrast, in dairy cattle breeding, the concept of an ...
How far have we come: 75 years ‘in clover’?
(New Zealand Grassland Association., 2006)
We reflect on what has been a recurring theme in the
history of agricultural research in NZ – the understanding
that while we grow white clover for its capacity to fix
nitrogen, this increase in fertility ultimately passes ...
Methods of reducing ripgut brome seed production and carcass damage
(New Zealand Grassland Association., 2008)
Ripgut brome (Bromus diandrus) is an annual grass weed
prevalent in dry, hill and high country regions throughout
the South Island. Its large seeds contaminate wool and
carcasses. Two studies were undertaken in 2006/2007 ...
Getting the most from your dairy support land - tips for allocating winter forages
(South Island Dairy Event (SIDE)., 2008-06)
As dairy farming businesses expand and the push for productivity improvement continues
there is increasing pressure to maximise milksolids production from the milking platform. A
consequence of this production drive is the ...
Survey of management practices of dairy cows grazing kale in Canterbury
(New Zealand Grassland Association., 2008)
Many dairy cows, particularly in southern New Zealand
have kale (Brassica olercaea) as a major component of
their winter diet. Anecdotal evidence suggests variable
results in cow body condition are achieved when kale is
used ...
Positive relationships between body weight of dairy heifers and their first-lactation and accumulated three-parity lactation production
(Elsevier on behalf of the American Dairy Science Association and the Federation of Animal Science Societies, 2019-03-01)
This study investigated the relationships between body weight (BW) and milk production of 140,113 New Zealand dairy heifers. Heifers were classified into 5 breed groups: Holstein-Friesian, Holstein-Friesian crossbred, ...
Metabolisable energy concentration in perennial ryegrass pastures: Multi-site analysis of effects of cultivar, nitrogen fertiliser and white clover content
(New Zealand Grassland Association, 2018-11-13)
To include metabolisable energy (ME) as a nutritive value factor for ryegrasses in the Forage Value Index (FVI) requires data for New Zealand cultivars on the effects of environmental and management ...
Specific genotypes of plantain (Plantago lanceolata) vary in their impact on sheep urine volume and nitrification in the urine patch
(New Zealand Grassland Association, 2018-11-13)
Plantain has the potential to reduce nitrate leaching through a number of mechanisms. In an indoor study, sheep were offered either perennial ryegrass or different plantain genotypes while aiming to achieve similar dry ...
Brief Communication: Effect of maternal diet in late gestation on development of dairy calves
(New Zealand Society of Animal Production (Inc), 2018)
To investigate whether feeding strategies to reduce urinary N excretion would have negative effects on calf development, two feeding systems were compared. A total of 190 pregnant, Friesian × Jersey dairy cows were randomly ...
