Assessing the ability of a stationary pasture height sensing device to estimate pasture growth and biomass
(New Zealand Grassland Association, 2019-11-04)
Good pasture management requires an accurate knowledge of whole-farm feedbase, yet most systems for measuring pasture growth are manually operated and time consuming. A newly developed pasture-measuring device enables ...
Dry matter intake and body condition score change of dairy cows grazing fodder beet, kale and kale-oat forage systems in winter
(NZGA, 2014)
Crop dry matter (DM) yield, DM utilisation and body condition score (BCS) of dairy cows were measured over two winters on an irrigated stony, free-draining Balmoral soil for three crop grazing systems: fodder beet (FB); ...
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 ...
Growth strategy of rhizomatous and non-rhizomatous tall fescue populations in response to defoliation
(MDPI, 2015-09)
The aim of this study was to determine the morphology of rhizome production, in two contrasting rhizomatous (R) and non-rhizomatous (NR) tall fescue (Schedonorus arundinaceus (Schreb.) Dumort) populations, and to assess ...
Plantain silage quality under variable management practices
(New Zealand Grassland Association, 2018-11-17)
Two studies investigated the effect of regrowth and additives on preservation and quality of plantain ensiled in spring using a micro-silage technique. Study 1 compared the effect of regrowth at four (4L), five (5L) or six ...
Dietary preference of dairy cows for perennial ryegrass cultivars growing with and without white clover
(New Zealand Society of Animal Production, 2016)
Dietary preference of dairy cows for eight perennial ryegrass cultivars (AberMagic, Alto, Base, Bealey, Commando, Kamo, One50 and Prospect) growing with and without white clover was examined at two vegetative stages (May ...
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 yield and urinary-nitrogen excretion of dairy cows grazing forb pasture mixtures designed to reduce nitrogen leaching
(Elsevier, 2018-03)
The effect of including a mixture of forbs in a standard perennial ryegrass-white clover pasture, with or without Italian ryegrass was investigated in a two-period grazing study comparing urinary nitrogen (N) excretion and ...
Effectiveness of strategies used to establish plantain in existing pastures
(New Zealand Grassland Association (NZGA), 2019-11-04)
In recent years plantain (Plantago lanceolata) has emerged as a potential forage for reducing nitrogen losses from dairy farm systems. However, achieving sufficient proportions of plantain in pastures to help meet target ...
Simulating the intake and nitrogen excretion from cows grazing forages fertilised with increasing rates of nitrogen
(New Zealand Society of Animal Production (Inc), 2018)
The dry matter intake (DMI), production, and urinary nitrogen (N) excretion of dairy cows grazing forage grown under increasing N fertiliser rates were explored using a mechanistic model of a grazing ruminant. The MINDY ...
