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 ...
Influence of the endophyte fungus in ryegrass on grazing preference by sheep
(Lincoln University, 1990)
Animal productivity may be enhanced through greater intake associated with the use of preferred pasture species provided they are of high nutritional value. Grazing preference by ewe hoggets was investigated in three grazing ...
Grazing preference for pasture species by sheep is affected by endophyte and nitrogen fertility
(New Zealand Grassland Association, 1993)
The grazing response of ewe hoggets offered tall
fescue, endophyte-infected (+E) or endophyte-free
(-E) perennial ryegrass all sown with white clover
into a fertile silt loam was examined in April
1990. In a second experiment ...
Persistence of ryegrass, tall fescue and cocksfoot following sequential annual sowings: Pasture yield, composition and density in 3 establishment years under sheep grazing in Canterbury
(New Zealand Grassland Association, 2018-11-13)
A long-term pasture persistence trial, consisting of repeated annual sowings, commenced in Canterbury in 2015 and is planned to continue until 2024. Preliminary results of the first 3 years sowings are reported. ...
High sugar ryegrasses for livestock systems in New Zealand
(New Zealand Grassland Association., 2007)
There has been mounting interest over the proposed
production and environmental benefits from using
perennial ryegrass cultivars bred to have higher water
soluble carbohydrate content (high sugar grasses). Here,
we objectively ...
Pasture production and botanical composition of high sugar and control ryegrasses with or without endophyte under irrigation in Canterbury
(New Zealand Grassland Association., 2009)
High sugar grasses and novel endophytes are two new
technologies promoted for pastoral farmers. While
assessing their value for pastoral farming it is important
to consider the interactive effects of these technologies
on ...
Effect of post grazing residual and concentrate feeding on milk production in early lactation
(New Zealand Society of Animal Production, 2013)
Two strategies to increase nutrient supply to early lactation dairy cows were compared and the cumulative effects on pasture quality and milk production were investigated. In a farmlet experiment the effect of feeding ...
Response of simple grass-white clover and multi-species pastures to gibberellic acid or nitrogen fertiliser in autumn
(NZ Grassland Association, 2013)
Herbage dry matter (DM) production, botanical composition and nutritive value of pastures were measured in response to the application of 24 g/ha gibberellic acid (GA; 60 g ProGibb®/ha) and 50 kg N/ha nitrogen fertiliser ...
Does mowing before grazing increase dry matter intake and milk yield?
(New Zealand Society of Animal Production, 2016)
Mowing pasture before allocation of herbage to dairy cows is one management strategy suggested to improve feed quality, increase herbage dry matter (DM) intake and increase milk solids yield. To test these hypotheses, ...
Milk production and urinary nitrogen excretion of dairy cows grazing perennial ryegrass-white clover and pure plantain pastures
(New Zealand Society of Animal Production (Inc), 2016)
Milk production and urinary nitrogen (N) concentration were measured in late lactation dairy cows grazing a perennial ryegrass-white clover pasture, pure plantain and an area that is comprised of 50% perennial ryegrass-white ...
