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 ...
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 ...
Urinary nitrogen concentration from dairy heifers grazing kale supplemented with either plantain or perennial ryegrass baleage in winter
(NZ Grassland Association, 2016)
The effect of feeding two different supplements (perennial ryegrass or plantain baleage) on urinary nitrogen (N) excretion from dairy heifers (8 months old, 180 kg liveweight (LW)) grazing kale was examined in two successive ...
Relationship between social dominance and milk production of dairy cows grazing pasture
(New Zealand Society of Animal Production, 2016-06)
The objectives of this experiment were to study factors determining social dominance of grazing dairy cows and the relationship between social dominance and milk production under grazing systems. A total of 252 spring ...
Supplementation of spring pasture with harvested fodder beet bulb alters rumen fermentation and increases risk of subacute ruminal acidosis during early lactation
(MDPI, 2020-08)
In a cross-over design, eight rumen cannulated dairy cows were used to explore the industry-recommended method for dietary transition to fodder beet (FB: Beta vulgaris L.) on changes to rumen fermentation and pH, milk ...
Ryegrass staggers and liveweight gain of ewe lambs and hoggets grazing four combinations of perennial ryegrass and strains of endophyte
(New Zealand Society of Animal Production, 2015-06-28)
Ryegrass staggers and live weight gain of Coopworth ewe lambs or hoggets were assessed over four eight week trials (two summer, two autumn) for four combinations of perennial ryegrass and strains of endophyte: Arrow with ...
